Abstract

This document sets forth final regulations regarding the increased credit amounts or the increased deduction amount available for taxpayers satisfying prevailing wage and registered apprenticeship (collectively, PWA) requirements established by the Inflation Reduction Act of 2022. These final regulations affect taxpayers intending to satisfy the PWA requirements to be eligible for increased amounts of Federal income tax credits or an increased deduction, including those intending to make elective payment elections for available credit amounts, and those intending to transfer increased credit amounts. These final regulations also affect taxpayers intending to satisfy the prevailing wage requirements to be eligible for increased amounts of those Federal income tax credits that do not have associated apprenticeship requirements. Additionally, these final regulations affect taxpayers who initially fail to satisfy the PWA requirements (or prevailing wage requirements, as applicable) and subsequently comply with the correction and penalty procedures in order to be deemed to satisfy the PWA requirements (or prevailing wage requirements, as applicable). Finally, these final regulations address specific PWA and prevailing wage recordkeeping and reporting requirements.

for taxpayers satisfying prevailing wage and registered apprenticeship 
(collectively, PWA) requirements established by the Inflation Reduction 
Act of 2022. These final regulations affect taxpayers intending to 
satisfy the PWA requirements to be eligible for increased amounts of 
Federal income tax credits or an increased deduction, including those 
intending to make elective payment elections for available credit 
amounts, and those intending to transfer increased credit amounts. 
These final regulations also affect taxpayers intending to satisfy the 
prevailing wage requirements to be eligible for increased amounts of 
those Federal income tax credits that do not have associated 
apprenticeship requirements. Additionally, these final regulations 
affect taxpayers who initially fail to satisfy the PWA requirements (or 
prevailing wage requirements, as applicable) and subsequently comply 
with the correction and penalty procedures in order to be deemed to 
satisfy the PWA requirements (or prevailing wage requirements, as 
applicable). Finally, these final regulations address specific PWA and 
prevailing wage recordkeeping and reporting requirements.

SUPPLEMENTARY INFORMATION:

Background

I. Overview

    This document contains final regulations that amend the Income Tax 
Regulations (26 CFR part 1) under sections 30C, 45, 45L, 45Q, 45U, 45V, 
45Y, 45Z, 48C, and 179D of the Internal Revenue Code (Code), as enacted 
or amended by the Inflation Reduction Act of 2022 (IRA), Public Law 
117-169, 136 Stat. 1818 (August 16, 2022).
    The IRA amended sections 30C, 45, 45L, 45Q, 48, 48C, and 179D to 
provide increased amounts of credits or an increased deduction, as 
applicable, for taxpayers who satisfy certain requirements and added 
sections 45U, 45V, 45Y, 45Z, and 48E to the Code to provide new 
credits, which also contain provisions for increased credit amounts for 
taxpayers who satisfy certain requirements. Increased credit amounts 
are available under sections 30C, 45, 45Q, 45V, 45Y, 45Z, 48, 48C, and 
48E, and an increased deduction is available under section 179D for 
taxpayers satisfying certain PWA requirements. Increased credit amounts 
are available under sections 45L and 45U for taxpayers satisfying 
certain prevailing wage requirements.\1\ The IRA includes correction 
and penalty provisions available in certain situations for taxpayers 
that have initially failed to satisfy the PWA requirements and are not 
otherwise eligible for the increased amount of credit or deduction 
because they do not qualify for an exception.
---------------------------------------------------------------------------

    \1\ The provisions in sections 45L and 45U relating to increased 
credit amounts do not contain apprenticeship requirements. For 
simplicity, where possible, the preamble to these final regulations 
uses the acronym PWA to refer to the prevailing wage and 
apprenticeship requirements generally, including the prevailing wage 
requirements in sections 45L and 45U.
---------------------------------------------------------------------------

    Increased amounts of credits or an increased deduction are 
generally available under sections 30C, 45, 45Q, 45V, 45Y, 48, 48E and 
179D with respect to certain facilities, properties, projects, 
technologies, or equipment if beginning of construction (or beginning 
of installation for section 179D) of the facility, property, project, 
technology, or equipment, as applicable, occurs before January 29, 2023 
(BOC Exception). Additionally, the increased credit amounts generally 
are available under sections 45, 45Y, 48, and 48E with respect to 
certain facilities, projects, and technologies, as applicable, with a 
maximum net output (or capacity for energy storage technology under 
section 48E) of less than one megawatt (One Megawatt Exception). 
Generally, if a taxpayer satisfies the PWA requirements, meets the BOC 
Exception, or meets the One Megawatt Exception, the amount of credit or 
deduction determined is equal to the otherwise determined amount of the 
underlying credit or deduction multiplied by five.

II. PWA Provisions

A. In General
    The principal PWA requirements are set forth in section 45(b)(6), 
(7), and (8). In general, section 45(b)(6) provides the increased 
credit amount for taxpayers satisfying the PWA requirements or meeting 
one of the exceptions, section 45(b)(7) provides the prevailing wage 
requirements (Prevailing Wage Requirements),\2\ and section 45(b)(8) 
provides the apprenticeship requirements (Apprenticeship 
Requirements).\3\
---------------------------------------------------------------------------

    \2\ The Prevailing Wage Requirements in sections 30C(g), 45L(g), 
45Q(h), 45U(d), 45V(e), 48(a)(10), 48C(e), and 179D(b) are similar 
to the requirements provided under section 45(b)(7). Sections 30C, 
45L, 48C, and 179D, however, do not require the payment of wages at 
rates not less than the prevailing rates after construction, re-
equipping, expansion, establishment, or installation, as applicable, 
ends. Sections 45Y(g)(9) and 45Z(f)(6)(A) adopt by cross-reference 
the Prevailing Wage Requirements under section 45(b)(7). Section 
48E(d)(3) adopts by cross-reference the Prevailing Wage Requirements 
under section 48(a)(10). Section 48(a)(10)(C) provides for a special 
5-year recapture rule that applies for purposes of the Prevailing 
Wage Requirements with respect to sections 48 and 48E.
    \3\ Sections 30C(g)(3), 45Q(h)(4), 45V(e)(4), 45Y(g)(10), 
45Z(f)(7), 48(a)(11), 48C(e)(6), 48E(d)(4), and 179D(b)(5) cross-
reference the Apprenticeship Requirements in section 45(b)(8). 
Sections 45L and 45U do not have Apprenticeship Requirements.
---------------------------------------------------------------------------

    In general, section 45 provides a credit for taxpayers producing 
electricity from qualified energy resources at a qualified facility 
during the 10-year period beginning on the date the facility was 
originally placed in service, and selling that electricity to unrelated 
persons during the taxable year. Under section 45(a), the credit is 
equal to 0.3 cents multiplied by the kilowatt hours of electricity: (i) 
produced by the taxpayer from qualified energy resources and at a 
qualified facility during the 10-year period beginning on the date the 
facility was originally placed in service, and (ii) sold by the 
taxpayer to an unrelated person during the taxable year. Under section 
45(b)(6), with respect to a qualified facility, if a taxpayer satisfies 
the PWA requirements, meets the BOC Exception, or meets the One 
Megawatt Exception, then the amount of the credit determined under 
section 45(a) is multiplied by five.
B. Prevailing Wage Requirements
    Section 45(b)(7)(A) provides that with respect to any qualified 
facility, ``the taxpayer shall ensure that any laborers

[[Page 53185]]

and mechanics employed by the taxpayer or any contractor or 
subcontractor in--(i) the construction of such facility, and (ii) with 
respect to any taxable year, for any portion of such taxable year which 
is within the [10-year period beginning on the date the qualified 
facility was originally placed in service], the alteration or repair of 
such facility, shall be paid wages at rates not less than the 
prevailing rates for construction, alteration, or repair of a similar 
character in the locality in which such facility is located as most 
recently determined by the Secretary of Labor, in accordance with 
subchapter IV of chapter 31 of title 40, United States Code [Davis-
Bacon Act or DBA].''
    The Davis-Bacon Act, enacted in 1931, requires the payment of 
minimum prevailing wages determined by the Department of Labor (DOL) 
for laborers and mechanics working on contracts entered into by Federal 
agencies and the District of Columbia, if such contracts are in excess 
of $2,000 and are for the construction, alteration, or repair of public 
buildings and public works. Section 3142 of the DBA requires that 
Federal agencies entering into contracts covered by the DBA include the 
requirements of the DBA in the contract, including the requirement to 
incorporate the applicable wage determinations that set forth the 
prevailing wages to be paid to laborers and mechanics. The Copeland 
Act, 40 U.S.C. 3145, sets forth a requirement that the contractor 
submit certified weekly payroll records to the contracting Federal 
agency. Congress has included DBA requirements in other laws, often 
referred to as the Davis-Bacon Related Acts, under which Federal 
agencies provide assistance for construction projects through grants, 
loans, insurance, and other methods. The DOL Wage and Hour Division 
(WHD) administers the DBA prevailing wage provisions.
C. Correction and Penalty Related to Failure To Satisfy Prevailing Wage 
Requirements
    Under section 45(b)(7)(B) of the Code, a taxpayer who is not 
eligible for the BOC Exception or the One Megawatt Exception and fails 
to satisfy the Prevailing Wage Requirements under section 45(b)(7)(A), 
is deemed to have satisfied those requirements if the taxpayer makes a 
correction payment to any laborer or mechanic who was paid wages at a 
rate below the required prevailing rate for any period during any year 
of the construction, alteration, or repair of the qualified facility 
and pays a penalty to the Internal Revenue Service (IRS).
    Under section 45(b)(7)(B)(i)(I), the amount of the correction 
payment is the sum of: (i) the difference between the amount of wages 
paid to the laborer or mechanic during the period and the amount of 
wages required to be paid to the laborer or mechanic during that period 
in order to meet the Prevailing Wage Requirements; and (ii) interest on 
the amount under (i) at the underpayment rate established under section 
6621 (determined by substituting six percentage points for three 
percentage points in section 6621(a)(2)) for the applicable period.
    Under section 45(b)(7)(B)(i)(II), the amount of the penalty is 
$5,000 multiplied by the total number of laborers and mechanics who 
were paid wages at a rate below the prevailing wage rate described in 
section 45(b)(7)(A) for any period during the year. Deficiency 
procedures do not apply with respect to the assessment or collection of 
this penalty pursuant to section 45(b)(7)(B)(ii).
    Under section 45(b)(7)(B)(iii), if the IRS determines that the 
failure to satisfy the Prevailing Wage Requirements is due to 
``intentional disregard'' of those requirements, then the correction 
payment to the laborer or mechanic is three times the amount that would 
otherwise be determined under section 45(b)(7)(B)(i)(I), and $10,000 is 
substituted for $5,000 in calculating the penalty under section 
45(b)(7)(B)(i)(II).
    Section 45(b)(7)(B)(iv) provides that once the IRS makes a final 
determination that a taxpayer has failed to satisfy the Prevailing Wage 
Requirements, the taxpayer must make the correction and penalty 
payments within 180 days after the final determination to be eligible 
for the increased credit amount. If the taxpayer does not make the 
required correction and penalty payments, and therefore is not allowed 
the increased credit amount, no penalty is assessed under section 
45(b)(7)(B).
D. Apprenticeship Requirements
    Under section 45(b)(8), with respect to the construction of any 
qualified facility, taxpayers must satisfy the Apprenticeship 
Requirements. The Apprenticeship Requirements impose rules regarding 
labor hours, apprentice-to-journeyworker ratios, and participation by 
qualified apprentices.
1. Labor Hours Requirement
    Section 45(b)(8)(A)(i) provides that ``[t]axpayers shall ensure 
that, with respect to construction of any qualified facility, not less 
than the applicable percentage of the total labor hours of the 
construction, alteration, or repair work (including such work performed 
by any contractor or subcontractor) with respect to such facility 
shall, subject to [section 45(b)(8)(B)], be performed by qualified 
apprentices'' (Labor Hours Requirement). For purposes of the Labor 
Hours Requirement, section 45(b)(8)(A)(ii) provides that the applicable 
percentage is: (i) in the case of a qualified facility the construction 
of which begins before January 1, 2023, 10 percent, (ii) in the case of 
a qualified facility the construction of which begins after December 
31, 2022, and before January 1, 2024, 12.5 percent, and (iii) in the 
case of a qualified facility the construction of which begins after 
December 31, 2023, 15 percent.
    Section 45(b)(8)(E)(i) defines ``labor hours'' as the total number 
of hours devoted to the performance of construction, alteration, or 
repair work by any individual employed by the taxpayer or by any 
contractor or subcontractor, and excluding any hours worked by foremen, 
superintendents, owners, or persons employed in a bona fide executive, 
administrative, or professional capacity (within the meaning of those 
terms in part 541 of title 29, Code of Federal Regulations). Section 
45(b)(8)(E)(ii) defines ``qualified apprentice'' as ``an individual who 
is employed by the taxpayer or by any contractor or subcontractor and 
who is participating in a registered apprenticeship program, as defined 
in section 3131(e)(3)(B).'' Section 3131(e)(3)(B) defines a 
``registered apprenticeship program'' as an apprenticeship program 
registered under the Act of August 16, 1937 (commonly known as the 
National Apprenticeship Act, 50 Stat. 664, chapter 663, 29 U.S.C. 50 et 
seq.) that meets the standards of subpart A of part 29 and part 30 of 
title 29 of the Code of Federal Regulations.\4\ The DOL Office of 
Apprenticeship (OA) administers provisions under the National 
Apprenticeship Act related to registered apprenticeship programs.
---------------------------------------------------------------------------

    \4\ Effective November 25, 2022, 29 CFR part 29 is no longer 
divided into subparts A and B because subpart B (Industry Recognized 
Apprenticeship Programs) was rescinded in a final rule published on 
September 26, 2022 (87 FR 58269). On January 17, 2024, the DOL 
released a notice of proposed rulemaking that would once again place 
apprenticeship standards in subpart A of part 29. See 89 FR 3118.
---------------------------------------------------------------------------

2. Ratio Requirement
    Under section 45(b)(8)(B), the Labor Hours Requirement is subject 
to any applicable requirements for apprentice-to-journeyworker ratios 
of the DOL or the applicable State apprenticeship agency (Ratio 
Requirement).

[[Page 53186]]

3. Participation Requirement
    Under section 45(b)(8)(C), each taxpayer, contractor, or 
subcontractor who employs four or more individuals to perform 
construction, alteration, or repair work with respect to the 
construction of a qualified facility must employ one or more qualified 
apprentices to perform such work (Participation Requirement).
E. Exceptions to Apprenticeship Requirements
1. In General
    Under section 45(b)(8)(D)(i), a taxpayer is not treated as failing 
to satisfy the Apprenticeship Requirements if: (i) the taxpayer 
satisfies the requirements described in section 45(b)(8)(D)(ii) (Good 
Faith Effort Exception), or (ii) in the case of any failure by the 
taxpayer to satisfy the Labor Hours Requirement under section 
45(b)(8)(A) and the Participation Requirement under section 
45(b)(8)(C), the taxpayer makes a penalty payment to the IRS 
(Apprenticeship Cure Provision).
2. Good Faith Effort Exception
    Under the Good Faith Effort Exception provided by section 
45(b)(8)(D)(ii), a taxpayer is deemed to have satisfied the 
Apprenticeship Requirements with respect to a qualified facility if the 
taxpayer has requested qualified apprentices from a registered 
apprenticeship program, and (i) such request has been denied, provided 
that such denial is not the result of a refusal by the taxpayer or any 
contractors or subcontractors engaged in the performance of 
construction, alteration, or repair work with respect to such qualified 
facility to comply with the established standards and requirements of 
the registered apprenticeship program, or (ii) the registered 
apprenticeship program fails to respond to such request within five 
business days after the date on which such registered apprenticeship 
program received such request.
3. Apprenticeship Cure Provision
    Under section 45(b)(8)(D)(i)(II), if the Good Faith Effort 
Exception does not apply, then the taxpayer will not be treated as 
failing to satisfy the Labor Hours Requirement or the Participation 
Requirement if the taxpayer makes a penalty payment to the IRS in an 
amount equal to the product of $50 multiplied by the total labor hours 
for which the Labor Hours Requirement or the Participation Requirement 
was not satisfied with respect to the construction, alteration, or 
repair work on the qualified facility. Under section 45(b)(8)(D)(iii), 
if the IRS determines that the failure was due to intentional disregard 
of the Labor Hours Requirement or Participation Requirement, then the 
penalty amount increases to $500 multiplied by the total labor hours 
for which the Labor Hours Requirement or Participation Requirement was 
not satisfied.

III. Other Increased Credit Amount Provisions

A. Beginning of Construction Exception
    Under the BOC Exception in section 45(b)(6)(B)(ii), a qualified 
facility the construction of which began prior to the date that is 60 
days after the IRS publishes guidance with respect to the requirements 
of section 45(b)(7)(A) and (8) is a facility eligible for the increased 
credit amount in section 45(b)(6). On November 30, 2022, the Department 
of the Treasury (Treasury Department) and the IRS published Notice 
2022-61 in the Federal Register (87 FR 73580, corrected in 87 FR 75141 
(Dec. 7, 2022)), providing guidance with respect to the PWA 
requirements in section 45(b)(7) and (8), including initial guidance 
for determining the beginning of construction under section 45 and 
other credits and the beginning of installation under section 179D. 
Therefore, if a taxpayer began construction or installation of a 
facility \5\ before January 29, 2023, then the taxpayer is eligible for 
the increased amount of credit or deduction without satisfying the PWA 
requirements, provided the taxpayer is otherwise eligible for the 
credit or deduction. Similar exceptions apply under sections 30C, 45Q, 
45V, 45Y, 48, 48E, and 179D.
---------------------------------------------------------------------------

    \5\ Notice 2022-61 defines facility as qualified facility, 
property, project, or equipment.
---------------------------------------------------------------------------

    For purposes of determining when construction or installation 
begins, Notice 2022-61 incorporates by reference the notices issued 
under sections 45,\6\ 45Q,\7\ and 48 \8\ (collectively, IRS Notices). 
The IRS Notices describe two methods of establishing that construction 
of a facility has begun: (i) starting physical work of a significant 
nature (Physical Work Test), and (ii) paying or incurring five percent 
or more of the total cost of the facility (Five Percent Safe Harbor).

---------------------------------------------------------------------------

    The IRS Notices provide that for purposes of the Physical Work Test 
and Five Percent Safe Harbor, taxpayers must demonstrate either 
continuous construction or continuous efforts (Continuity Requirement) 
regardless of whether the Physical Work Test or the Five Percent Safe 
Harbor was used to establish the beginning of construction. Whether a 
taxpayer meets the Continuity Requirement under either test is 
determined by the relevant facts and circumstances.
    The IRS Notices also provide for a Continuity Safe Harbor under 
which a taxpayer will be deemed to satisfy the Continuity Requirement 
provided a qualified facility is placed in service no more than four 
calendar years after the calendar year during which construction of the 
qualified facility began for purposes of sections 45 and 48, and no 
more than six calendar years after the calendar year during which 
construction of the qualified facility or carbon capture equipment 
began for purposes of section 45Q. For purposes of the Continuity Safe 
Harbor, certain offshore projects and projects built on Federal land 
under sections 45 and 48 satisfy the Continuity Requirement if such a 
project is placed into service no more than ten calendar years after 
the calendar year during which construction of the project began.
    Until the Treasury Department and the IRS issue further guidance on 
determining when construction or installation begins, taxpayers may 
continue to rely on the guidance provided in Notice 2022-61 and the IRS 
Notices. Specifically, to determine when construction begins for 
purposes of sections 30C, 45V, 45Y, and 48E, principles similar to 
those under Notice 2013-29 regarding the Physical Work Test and Five 
Percent Safe Harbor apply, and taxpayers satisfying either test will be 
considered to have begun construction. In addition, principles similar 
to those provided in the IRS Notices regarding the Continuity 
Requirement for purposes of sections 30C, 45V, 45Y, and 48E apply. 
Whether a taxpayer meets the Continuity Requirement under either test 
is determined by the relevant facts and circumstances. Similar 
principles to those under section 3 of Notice 2016-31 regarding the 
Continuity Safe Harbor also apply for purposes of sections 30C, 45V, 
45Y, and 48E. Taxpayers may rely on the Continuity Safe Harbor with

[[Page 53187]]

respect to those sections, provided the facility is placed in service 
no more than four calendar years after the calendar year during which 
construction began.
    For purposes of section 179D, installation of energy efficient 
commercial building property, energy efficient building retrofit 
property, or property installed pursuant to a qualified retrofit plan 
has begun if a taxpayer generally satisfies principles similar to the 
Physical Work Test and the Five Percent Safe Harbor described in 
section 2.02 of Notice 2022-61 regarding the beginning of construction 
under Notice 2013-29. The relevant facts and circumstances will 
ultimately determine whether a taxpayer has begun installation.
    For purposes of sections 45, 45Q, and 48, the IRS Notices will 
continue to apply under each respective Code section, including 
application of the Physical Work Test and Five Percent Safe Harbor, and 
the rules regarding the Continuity Requirement and Continuity Safe 
Harbors.
B. One Megawatt Exception
    Under the One Megawatt Exception in section 45(b)(6)(B)(i), a 
qualified facility that has a maximum net output of less than one 
megawatt (as measured in alternating current) is a facility eligible 
for the increased credit amount. Similar exceptions apply for a 
qualified facility with a maximum net output of less than one megawatt 
(as measured in alternating current) under sections 45Y(a)(2)(B)(i) and 
48E(a)(2)(A)(ii)(I); an energy project with a maximum net output of 
less than one megawatt of electrical (as measured in alternating 
current) or thermal energy under section 48(a)(9)(B)(i); and energy 
storage technology with a capacity of less than one megawatt under 
section 48E(a)(2)(B)(ii)(I).

IV. Prior Guidance

    On October 24, 2022, the Treasury Department and the IRS published 
Notice 2022-51, 2022-43 I.R.B. 331, requesting comments on aspects of 
the increased amounts of credits and deduction enacted or amended by 
the IRA, including the PWA provisions. On November 30, 2022, the 
Treasury Department and the IRS published Notice 2022-61. Notice 2022-
61 provided guidance on the PWA requirements that generally apply under 
sections 30C, 45, 45L, 45Q, 45U, 45V, 45Y, 45Z, 48, 48C, 48E, and 179D. 
Additionally, as discussed in Section III.A. of this Background, Notice 
2022-61 established the 60-day period described in sections 
30C(g)(1)(C)(i), 45(b)(6)(B)(ii), 45Q(h)(2), 45V(e)(2)(A)(i), 
45Y(a)(2)(B)(ii), 48(a)(9)(B)(ii), 48E(a)(2)(A)(ii)(II) and 
(a)(2)(B)(ii)(II), and 179D(b)(3)(B)(i) for purposes of the BOC 
Exception. Finally, Notice 2022-61 provided guidance for determining 
the beginning of construction under sections 30C, 45, 45Q, 45V, 45Y, 
48, and 48E, and the beginning of installation under section 179D.
    On August 30, 2023, the Treasury Department and the IRS published a 
notice of proposed rulemaking and a notice of public hearing (REG-
100908-23) in the Federal Register (88 FR 60018), corrected in 88 FR 
73807 (Oct. 27, 2023), and 89 FR 25550 (April 11, 2024), providing 
guidance on the PWA requirements under sections 30C, 45, 45L, 45Q, 45U, 
45V, 45Y, 45Z, 48, 48C, 48E, and 179D (Proposed Regulations). The 
provisions of the Proposed Regulations are explained in greater detail 
in the preamble to the Proposed Regulations.
    On November 22, 2023, the Treasury Department and the IRS published 
a notice of proposed rulemaking and a notice of public hearing (REG- 
132569-17) in the Federal Register (88 FR 82188), providing guidance 
under section 48. Among other matters, the proposed regulations under 
section 48 (Section 48 Proposed Regulations) withdrew and reproposed 
the regulations in Sec.  1.48-13 regarding the PWA requirements under 
section 48, the One Megawatt Exception under section 48(a)(9)(B)(i), 
and the recapture rules under section 48(a)(10)(C) related to the 
Prevailing Wage Requirements. These final regulations do not include 
final regulations under section 48. Additionally, because proposed 
Sec.  1.48E-3 would have incorporated the rules of proposed Sec.  1.48-
13 by cross-reference, these final regulations do not include final 
regulations under section 48E. The Treasury Department and the IRS 
intend to issue final regulations with respect to the PWA Requirements 
in proposed Sec.  1.48-13 and proposed Sec.  1.48E-3 in future Treasury 
decisions.
    The Proposed Regulations provided that taxpayers may rely on 
proposed Sec.  1.48E-3 with respect to construction of a qualified 
facility on or after January 29, 2023, and on or before the date 
proposed Sec.  1.48E-3 publishes as a final regulation in the Federal 
Register, provided, that beginning after the date that is 60 days after 
August 29, 2023, taxpayers follow the proposed regulations in their 
entirety and in a consistent manner. The Section 48 Proposed 
Regulations similarly provided that taxpayers may rely on proposed 
Sec.  1.48-13 with respect to construction of a property or project 
beginning on or after January 29, 2023, and on or before the date 
proposed Sec.  1.48-13 publishes as a final regulation in the Federal 
Register, provided, that beginning after the date that is 60 days after 
August 29, 2023, taxpayers follow proposed Sec.  1.48-13 in its 
entirety and in a consistent manner. These final regulations do not 
change the reliance provided with respect to proposed Sec.  1.48-13 and 
proposed Sec.  1.48E-3.
    Comments received regarding the specific PWA requirements under 
sections 48 and 48E, the One Megawatt Exception under sections 48 and 
48E, and the recapture rules contained in section 48(a)(10)(C), all 
whether in response to the Proposed Regulations or the Section 48 
Proposed Regulations, will be addressed in the future Treasury decision 
adopting those rules as final regulations. Other comments on the PWA 
requirements (including comments that referenced section 48 or section 
48E, but addressed the PWA requirements more generally) were considered 
in the drafting of these final regulations and are discussed herein.
    On June 3, 2024, the Treasury Department and the IRS published a 
notice of proposed rulemaking and a notice of public hearing (REG-
119283-23) in the Federal Register (89 FR 47792), proposing guidance 
under sections 45Y and 48E (Section 45Y/48E Proposed Regulations). In 
the Section 45Y/48E Proposed Regulations, the Treasury Department and 
the IRS requested comments on the proposed definition of a qualified 
facility with a maximum net output of less than one megawatt (as 
measured in alternating current) for purposes of the One Megawatt 
Exception under section 45Y(a)(2)(B)(i). All comments received 
pertaining to the One Megawatt Exception under section 45Y(a)(2)(B)(i), 
whether in response to the Proposed Regulations or the Section 45Y/48E 
Proposed Regulations, will be addressed in future guidance under 
section 45Y finalizing those rules. General PWA comments that were 
received in response to the Proposed Regulations and that referenced 
section 45Y are discussed throughout this Summary of Comments and 
Explanation of Revisions because they were considered in the drafting 
of these final regulations.

Summary of Comments and Explanation of Revisions

    This Summary of Comments and Explanation of Revisions summarizes 
the Proposed Regulations, all the substantive comments submitted in 
response to the Proposed Regulations, and revisions adopted by these 
final regulations. The Treasury Department

[[Page 53188]]

and the IRS received 342 written comments in response to the Proposed 
Regulations. The comments are available for public inspection at 
<a href="https://www.regulations.gov">https://www.regulations.gov</a> or upon request. After full consideration 
of the comments received, these final regulations adopt the Proposed 
Regulations with modifications in response to such comments as 
described in this Summary of Comments and Explanation of Revisions.
    Most comments addressed the PWA requirements in general, without 
identifying a specific Code section. These comments are primarily 
addressed in Sections I. through VIII. of this Summary of Comments and 
Explanation of Revisions, and revisions that have been made in response 
to these comments are also typically described in general terms, or by 
reference to section 45, which sets forth the principal PWA 
requirements. Thus, the terms qualified facility and facility as used 
in Sections I. through VIII. of this Summary of Comments and 
Explanation of Revisions generally includes qualified equipment, 
qualified residence, qualified project, and qualified property for 
purposes of sections 30C, 45, 45L, 45Q, 45U, 45V, 45Y, 45Z, 48C, and 
179D, as applicable. References to an increased credit amount in 
Sections I. through VIII. of this Summary of Comments and Explanation 
of Revisions include the increased deduction amount available under 
section 179D, as applicable. Comments specifically addressing the PWA 
requirements in sections 30C, 45L, 45Q, 45U, 45V, 45Y, 45Z, 48C, and 
179D are described in Section IX. of this Summary of Comments and 
Explanation of Revisions.
    Comments summarizing the statute or the Proposed Regulations, 
recommending statutory revisions, and addressing issues that are 
outside the scope of this rulemaking (such as revising other Federal 
regulations and recommending changes to IRS forms) are generally not 
addressed in this Summary of Comments and Explanation of Revisions or 
adopted in these final regulations. Some commenters requested 
additional time to submit comments. The Proposed Regulations required 
all comments to be received by October 30, 2023; however, comments 
received by April 25, 2024, were considered in drafting these final 
regulations. In addition to addressing the comments received in 
response to the Proposed Regulations, the final regulations also 
include non-substantive grammatical or stylistic changes to the 
Proposed Regulations.

I. Pre-Filing Activities

A. Applicability of the Davis-Bacon Act in General <SUP>9</SUP>
---------------------------------------------------------------------------

    \9\ All references to the DBA regulations throughout this 
Summary of Comments and Explanation of Revisions include updates to 
the DBA regulations published in a final rule on August 23, 2023 (88 
FR 57526).
---------------------------------------------------------------------------

    Under section 45(b)(7)(A), the increased credit amount provided by 
section 45(b)(6) is available with respect to a qualified facility if, 
among other requirements, a taxpayer ensures that laborers and 
mechanics are, ``paid wages at rates not less than the prevailing rates 
for construction, alteration, or repair of a similar character in the 
locality in which such facility is located as most recently determined 
by the Secretary of Labor, in accordance with'' the DBA. As explained 
in the preamble to the Proposed Regulations, the phrase ``in accordance 
with'' means ``in agreement or harmony with; in conformity to; 
according to.'' \10\ In interpreting the ``in accordance with'' 
language, the preamble to the Proposed Regulations explained that the 
Treasury Department and the IRS proposed to incorporate those 
requirements of the DBA that are relevant for the purposes of section 
45(b)(7)(A) and the intent of the IRA, and that are necessary for, and 
consistent with, sound tax administration.
---------------------------------------------------------------------------

    \10\ In accordance with, Oxford English Dictionary, <a href="https://www.oed.com/search/dictionary/?scope=Entries&q=in+accordance+with">https://www.oed.com/search/dictionary/?scope=Entries&q=in+accordance+with</a> 
(last visited Aug. 8, 2023); see Accordance, Merriam-Webster's 
Collegiate Dictionary (11th ed. 2006) (meaning agreement, 
conformity).
---------------------------------------------------------------------------

    Under the DBA, the DOL determines the wage rates that are 
``prevailing'' for each classification of covered laborers and 
mechanics in the geographic area in which work is to be performed and 
publishes general wage determinations providing that information to the 
public. Under the DBA, Federal contracting agencies follow specified 
procedures for incorporating DBA requirements and wage determinations 
into covered contracts. Pursuant to the Copeland Act, contractors are 
required to submit certified weekly payroll records to the contracting 
agency. Under the DBA regulations, the contracting agency and the DOL 
WHD have responsibility to ensure compliance with prevailing wage 
requirements by engaging in periodic audits or investigations of 
contracts, including examination of payroll data.
    The Proposed Regulations would have largely adopted DBA guidance 
relating to applicable wage rates and wage determinations and the 
meaning of pertinent terms such as ``laborer'' and ``mechanic''; 
``construction, alteration, or repair''; ``wages''; and ``employed.'' 
The Proposed Regulations would not have incorporated the DBA (or 
Copeland Act) guidance regarding provisions required to be included in 
contracts, those provisions related to the reporting of certified 
weekly payroll records by contractors to contracting agencies, and the 
various enforcement processes that are available to the DOL and the 
contracting agencies to address DBA noncompliance.
    As explained in the preamble to the Proposed Regulations, this 
approach was intended to reflect the substantive differences between 
the DBA and the Code. Under the DBA, a contractor is required to pay 
prevailing wages as a condition of a Federal contract award. Under 
section 45, although the requirement to ensure the payment of wages at 
rates not less than the prevailing rates is generally triggered when 
construction of a facility begins, that requirement becomes legally 
binding only if a tax return claiming the increased credit amount is 
filed. The Code does not require taxpayers who do not seek an increased 
credit amount under section 45(b)(6) to ensure the payment of 
prevailing wages at the beginning of construction, alteration, or 
repair of a facility. Furthermore, under the correction and penalty 
provisions in section 45(b)(7)(B)(i)(I) and 45(b)(7)(B)(i)(II), 
taxpayers may remedy prior failures to pay wages at rates not less than 
the prevailing rates, even after a return is filed, and still be 
eligible for the increased credit amount. In addition, a taxpayer that 
satisfies the BOC Exception or the One Megawatt Exception, if 
applicable, may generally claim the increased credit amount regardless 
of whether laborers and mechanics were paid prevailing wages.
    Several commenters suggested that the final regulations should 
incorporate additional requirements from the DBA, instead of limiting 
the incorporation to those that the Treasury Department and the IRS 
determine are relevant for purposes of claiming the increased credit 
amount and that are necessary for, and consistent with, sound tax 
administration. Some commenters asserted that not incorporating all 
elements of the DBA framework was arbitrary and capricious and contrary 
to the statute. Some commenters alleged that the Proposed Regulations 
failed to adequately address the increased chance of improperly claimed 
credits by relying too heavily on post-filing enforcement. One 
commenter stated that post-filing enforcement by the IRS does not 
guarantee workers' rights, including notice of entitlement to the 
prevailing wage, a complaint procedure to report

[[Page 53189]]

noncompliance, protections against retaliation, or a requirement that 
workers be guaranteed any wage by an enforceable contract. The 
commenters also stated that the reliance on post-filing compliance was 
inconsistent with the DBA and would lead to fraud, noncompliance, and 
evasion of the tax rules. At least one commenter suggested that 
incorporating all of the DBA requirements is necessary to more 
generally address issues of fraud in the construction industry. One 
commenter opined that although the IRA differed from traditional Davis-
Bacon Related Acts that expressly adopt the DOL's existing 
implementation framework and confer primary enforcement authority upon 
the DOL, this was because the IRA was enacted through reconciliation. 
The commenter stated that this should not impact the implementation of 
the prevailing wage provisions.
    Although several commenters supported a more expansive 
incorporation of the DBA, many other commenters stated that the 
Proposed Regulations took the correct approach regarding incorporation 
of the DBA. One commenter suggested that given the unique challenges of 
applying a system arising in Federal contracting to the IRA's tax 
credit regime, Congress did not limit the Treasury Department and the 
IRS to adopting the DBA requirements and enforcement scheme word-for-
word and without modification. Many commenters acknowledged the need 
for the Treasury Department and the IRS to take a reasonable approach 
to interpret a Code provision that references a Federal law applicable 
to Federal contracts.
    These final regulations do not alter the general approach taken in 
the Proposed Regulations of incorporating DBA guidance for purposes of 
the PWA requirements only if it is relevant for the purposes of section 
45(b)(7)(A) and the intent of the IRA, and necessary for, and 
consistent with, sound tax administration. The Treasury Department and 
the IRS recognize the importance of ensuring compliance with the 
statute such that workers benefit from the payment of prevailing wages 
on projects for which the increased amount of credit is claimed and 
find that the general approach in the Proposed Regulations promotes 
that goal within the constraints of the statute and in furtherance of 
sound tax administration. Consistent with this framework, the final 
regulations encourage taxpayers to adopt certain practices for ensuring 
compliance in the interest of fulfilling statutory intent and 
furthering sound tax administration.
    The Treasury Department and the IRS disagree with the assertion 
that the Proposed Regulations were arbitrary and capricious. This 
Summary of Comments and Explanation of Revisions reiterates and expands 
upon the rationale for applying the DBA provisions that are relevant 
for purposes of claiming the increased tax credit and consistent with 
sound tax administration. If Congress intended for the same DBA 
requirements to apply under the IRA, it would have so provided. The 
Treasury Department and the IRS are required to implement statutory 
language as enacted, regardless of the procedure under which the 
legislation was passed (for example, reconciliation). As enacted, the 
statute does not indicate that the regulations setting forth the PWA 
requirements must mirror the DBA in every instance. As noted in the 
preamble to the Proposed Regulations, ``in accordance with'' means ``in 
agreement or harmony with; in conformity to; according to.'' This does 
not require exact duplication or incorporation. The differences in 
statutory language and context reflect the very significant differences 
between the administration of the wage provisions of Federal contracts 
and the administration of the tax system, and the statute provides 
flexibility for the IRS to incorporate the requirements from the DBA 
that are appropriate for tax administration purposes.
    The IRS's authority to determine a taxpayer's compliance with the 
PWA requirements generally arises after the taxpayer files a claim for 
the increased tax credit. Because taxpayers may choose not to claim the 
increased credit amount, the IRS cannot determine a taxpayer's 
compliance or engage in enforcement activities before the taxpayer 
files a tax return claiming the increased credit amount. Imposing pre-
filing requirements through regulations would not be a reasonable 
interpretation of the statutory language and would not permit the IRS 
to enforce the PWA requirements in advance of filing. Many of the DBA 
requirements (for example, certified weekly payroll, public notice of 
wage classifications and wage rates, required contract provisions) are 
either statutorily required under the DBA (or a related act) or 
designed to apply to all Federal construction contracts with certainty 
at the time of contract award (that is, in advance of work being 
performed). Those same pre-filing requirements are not prescribed in 
the Code.
    As acknowledged by many commenters, the Treasury Department and the 
IRS need to take a reasonable approach to interpret a Code provision 
that references a Federal law applicable to Federal contracts (a system 
that applies with certainty in the case of a Federal contracting agency 
that solicits bids for a contract) in the context of Federal taxes (a 
system designed to function with a compliance and enforcement framework 
that follows only after the filing of tax returns).
    Many commenters recognized that the PWA requirements are not 
binding until the tax return claiming the credit is filed, yet they 
still requested that the IRS impose several additional reporting, 
notice, and other requirements in advance of filing for the credit. As 
the requirement to pay prevailing wages does not become binding until a 
taxpayer files a claim for the increased amount of credit, and the IRS 
has a well-established record of effective post-filing enforcement, the 
final regulations do not adopt these requests. The Treasury Department 
and the IRS have also determined that imposing additional pre-filing 
requirements on taxpayers could discourage taxpayers from seeking the 
increased amount of credit available under the IRA, resulting in fewer 
workers receiving prevailing wages. The Treasury Department and the IRS 
will not impose pre-filing requirements that unnecessarily raise 
compliance costs, especially for small businesses, and provide no 
meaningful benefit to the IRS in administering the tax system.
    In reviewing the public comments, the Treasury Department and the 
IRS have decided to adopt key aspects of the Proposed Regulations and 
have also determined that certain changes to the Proposed Regulations 
would be appropriate to support compliance with the PWA requirements, 
and to encourage taxpayers to adopt certain practices. The Treasury 
Department and the IRS have made these determinations after 
consultation with the DOL WHD and OA. Those changes are discussed 
throughout this Summary of Comments and Explanation of Revisions. 
Accordingly, as discussed in Section VII.D.3. of this Summary of 
Comments and Explanation of Revisions, in cases in which it is 
necessary for and consistent with sound tax administration, these final 
regulations expand on the factors demonstrating intentional disregard 
to reflect the value of these practices. These additional factors 
incorporate the spirit and rationale of commenters' suggestions by 
addressing whether a taxpayer has (among other actions): (i) conducted 
regular reviews of the applicable prevailing wage rate that must be 
paid to laborers and mechanics and the appropriate classification of 
such

[[Page 53190]]

laborers and mechanics based on actual job duties; (ii) investigated 
complaints of retaliation or adverse action resulting from reports of 
suspected failures to pay prevailing wages and/or classify workers in 
accordance with applicable wage determinations, and taken appropriate 
actions to remedy any retaliation or adverse action and prevent it from 
reoccurring; and (iii) provided laborers and mechanics with paystubs 
(or access to individual payroll records) reflecting the amount being 
paid per pay period (including the specific hourly rate and all 
deductions from wages).
B. Specific Pre-Filing Activities Required Under the DBA
    Some commenters requested that the final regulations incorporate 
certain pre-filing requirements in line with DBA requirements, to 
prevent fraud and ensure that workers are paid wages at rates not less 
than the prevailing rates to which they are entitled. Specifically, 
commenters recommended that the final regulations require: (i) the 
submission of certified weekly or monthly payroll records or other 
compliance reports and the government's regular review and verification 
of those submitted records through job site visits and interviews with 
workers, and (ii) that taxpayers, contractors, and subcontractors 
include DBA provisions in contracts and post applicable wage rates on 
job sites in prominent and accessible locations.
1. Certified Payroll Records, Other Compliance Reporting, and 
Government Review of This Reporting
    Some commenters suggested that requiring the submission of weekly 
or monthly certified payroll records to the IRS or the DOL would allow 
the IRS to monitor compliance with the PWA requirements. Other 
commenters similarly suggested that the final regulations require the 
submission of sworn monthly compliance reports to the IRS to allow for 
effective monitoring of compliance with the statute prior to filing. 
One commenter suggested that the IRS should regularly review the 
certified payroll records submitted by contractors and subcontractors, 
conduct job site visits, and interview workers to ensure that the 
information reported in the certified payroll records is accurate, and 
provides taxpayers with an opportunity to correct any failures in 
advance of filing. This commenter acknowledged that the IRS would not 
be able to withhold funds or assess penalties in connection with any 
pre-filing review, because the requirement to pay prevailing wages is 
not binding until the taxpayer files a tax return claiming the 
increased credit amount. One commenter stated that a requirement to 
regularly certify payroll will deter bad actors and preclude falsified 
payroll records.
    Several commenters supported the approach in the Proposed 
Regulations to not require the regular submission of payroll records. 
One commenter stated that the submission of weekly certified payroll 
records would not assist the IRS with efficient administration of the 
increased credit amount provisions. Additionally, several other 
commenters stated that the requirement to submit certified weekly 
payroll records would be burdensome on taxpayers. Finally, one 
commenter agreed that submission of certified weekly payroll to the IRS 
would not be in furtherance of sound tax administration, but the 
commenter requested that contractors and subcontractors be required to 
submit certified weekly payroll to taxpayers. The commenter asserted 
that this could be a good way for taxpayers to monitor the activities 
of contractors and subcontractors.
    Applying the principle outlined in Section I.A. of this Summary of 
Comments and Explanation of Revisions to incorporate only the DBA 
requirements that are relevant for claiming the increased credit amount 
and consistent with sound tax administration, the comments requesting 
that the final regulations require the submission of pre-filing 
certified payroll records or other sworn reports, the pre-filing review 
of submitted payroll records, job site visits by the IRS, and 
interviews of workers regarding the accuracy of submitted information 
are not adopted. While these comments are not adopted, in the context 
of an examination, the IRS routinely engages in activities such as 
review of payroll records, site visits, and taxpayer interviews.
    The comments requesting that the final regulations require the 
submission of pre-filing payroll information or sworn compliance 
reports appear to assert that the IRS would be able to easily discern 
noncompliance on the face of payroll records or other sworn reports 
submitted in advance of a taxpayer filing any claim for a related tax 
credit. To the contrary, the requirement to pay prevailing wages 
becomes binding only if a tax return claiming the increased credit 
amount is filed. Payroll records or other sworn reports relating to the 
payment of wages before a return claiming the actual increased credit 
amount is filed would provide minimal benefit to the IRS's enforcement 
actions, and would impose considerable administrative work on 
taxpayers, including those who may not eventually claim the increased 
credit amount. Many commenters acknowledge that this information would 
not be used until the increased credit amount is claimed. The Treasury 
Department and the IRS decline to impose these additional 
administrative tasks on taxpayers because the information would provide 
minimal benefit to the IRS in advance of a taxpayer filing a return 
claiming the credit.
    However, the Treasury Department and the IRS agree that there may 
be advantages in taxpayers obtaining regular payroll records from 
contractors and subcontractors. Accordingly, these final regulations 
add as a factor for intentional disregard whether a taxpayer (or a 
third party acting on behalf of the taxpayer) has regularly reviewed 
payroll information of its contractors and subcontractors or has 
required its contractors or subcontractors to regularly provide payroll 
information to the taxpayer (or a third party acting on behalf of the 
taxpayer). Furthermore, as discussed in Section X.A. of this Summary of 
Comments and Explanation of Revisions, these final regulations adopt 
and expand upon the recordkeeping requirements in the Proposed 
Regulations and clarify that the DOL Form WH-347 may be used to satisfy 
some of the recordkeeping requirements.
2. Mandatory Incorporation of DBA Contract Requirements and Posting of 
Applicable Prevailing Wage Determinations
    The Proposed Regulations would have encouraged certain behaviors 
that are very similar to those required of contractors under the DBA as 
factors considered for intentional disregard. These behaviors, which 
the Treasury Department and the IRS view as indicative of an intent to 
comply with the Prevailing Wage Requirements, would have included 
incorporating provisions in any contracts entered with contractors that 
require payment by the contractors and any subcontractors of wages at 
rates not less than the prevailing rates and posting the applicable 
prevailing wage rates in a prominent place for the duration of the 
construction, alteration, or repair of the facility or otherwise 
notifying employees of the applicable prevailing wage rates.
    Some commenters suggested that taxpayers should be required to 
include certain contract provisions required by section 3142(c) of the 
DBA in their contracts with contractors and subcontractors. Some 
commenters recommended the final regulations

[[Page 53191]]

mandate specific contract terms, including the taxpayer's intent to 
claim the credit, the expected wage classifications of laborers and 
mechanics who will work on the project, estimates of apprenticeship 
hours, and flow-down responsibility clauses requiring compliance with 
the PWA requirements by all contractors and subcontractors. 
Additionally, commenters suggested that all solicitations, contracts, 
and subcontracts include clauses committing to the proper hiring and 
involvement of qualified apprentices under the Apprenticeship 
Requirements.
    Commenters also recommended that the final regulations adopt the 
requirement in section 3142(c)(2) of the DBA that prevailing wage rates 
must be posted by employers on the job site in a prominent and 
accessible location where they can be easily seen by workers. The 
Proposed Regulations would have included as a factor to be considered 
in the determination of whether a failure to satisfy the Prevailing 
Wage Requirements was due to intentional disregard, whether the 
taxpayer posted in a prominent place at the facility or otherwise 
provided written notice to laborers and mechanics during the 
construction, alteration, or repair of the facility, of the applicable 
wage rate(s) as determined by the DOL for all classifications of work 
to be performed for the construction, alteration, or repair of the 
facility, and that in order to be eligible to claim certain tax 
benefits, employers must ensure that laborers and mechanics are paid 
wages at rates not less than such wage rates. Although commenters were 
supportive of this factor, some commenters were critical of the fact 
that the information proposed for the notice leaves open the question 
of whether the worker is actually entitled to prevailing wages because 
the worker may not know whether an increased credit amount is being 
claimed with respect to the work they are performing. One commenter 
further requested that the poster include language regarding the right 
to be properly classified as an employee, the right to be free from 
retaliation related to immigration status, and information regarding 
how to contact the IRS. One commenter suggested requiring each 
contractor and subcontractor employing workers on projects for which an 
increased credit amount could be claimed to provide each worker with an 
individualized written notice identifying their respective 
classification and the prevailing wage rate to which they are entitled. 
The commenter suggested requiring notice to be made no later than when 
construction, alteration, or repair begins, and delivering the 
suggested notice along with workers' paychecks.
    Although both contract language and the posting of the applicable 
prevailing wage rates is required by the DBA, no similar provision 
exists in section 45(b)(7) of the Code that would require taxpayers to 
include specific terms in a contract or post prevailing wage rates 
during construction. Applying the principle outlined in Section I.A. of 
this Summary of Comments and Explanation of Revisions to incorporate 
only the DBA requirements that are relevant for claiming the increased 
credit amount and consistent with sound tax administration, the 
Treasury Department and the IRS have decided not to require specific 
DBA or other PWA-related provisions in private commercial contracts. 
These agreements are executed well before a tax return claiming the 
credit is filed. Similarly, the final regulations do not require the 
posting of applicable wage rates, because a taxpayer may decide to 
claim the increased credit amount after construction has started. 
Requests regarding the posting of information related to general rights 
of workers under State labor laws or other Federal laws are outside the 
scope of these final regulations. For these reasons, the comments 
requesting that the final regulations require the incorporation of DBA-
contract provisions and the posting of applicable prevailing wage rates 
are not adopted.
    However, there is likely a benefit to taxpayers seeking to comply 
with the PWA requirements if the requirement to pay prevailing wages 
and hire qualified apprentices is incorporated in the terms of any 
contract with respect to the construction, alteration, or repair of a 
facility, including lower-tier agreements between contractors and 
subcontractors, and if the laborers and mechanics who are employed in 
the construction of a facility are informed of the applicable 
prevailing wage rates that would be required if the taxpayer claims the 
increased credit amount. The Proposed Regulations would have encouraged 
this behavior from taxpayers who know they are going to claim the 
increased credit amount, and the final regulations incorporate and 
expand upon the list of factors that may be considered by the IRS for 
purposes of determining if a failure to satisfy the PWA requirements 
was due to intentional disregard.
C. Including Other Conditions as a Prerequisite for Claiming the 
Increased Amount of Credit
    Some commenters suggested that the final regulations should require 
taxpayers to provide advance notice to the IRS, the DOL, potential 
employees, and the general public of their intent to claim the 
increased credit amount by satisfying the PWA requirements to provide 
clarity to workers. Specifically, one commenter suggested requiring 
taxpayers to file a statement of intent to claim the increased credit 
amount with the DOL WHD, which would then be available for public 
review to enable interested parties to monitor projects that may be 
subject to the PWA requirements. Another commenter recommended 
requiring taxpayers to provide notice to workers, before the start of 
any project for which an increased credit amount could be claimed, of 
their intention to claim the increased credit amount by satisfying the 
PWA requirements.
    Consistent with the principles outlined in Section I.A. of this 
Summary of Comments and Explanation of Revisions, the final regulations 
do not adopt these suggestions. Requiring taxpayers to declare an 
intent to claim an increased credit amount would provide no meaningful 
benefit for the IRS's administration of the PWA requirements, and would 
impose additional pre-filing requirements on taxpayers. Section 
45(b)(6) does not require taxpayers to declare an intent to claim the 
increased credit amount. However, as noted previously, posting or 
otherwise providing general information about applicable wage rates is 
a good practice for taxpayers to incorporate if the taxpayer is 
planning to claim the increased credit amount. The final regulations 
retain these practices as a factor that may be considered by the IRS 
for purposes of determining if a failure to satisfy the Prevailing Wage 
Requirements was due to intentional disregard.
    Commenters also asked that the final regulations require a pre-
filing registration or reporting system, similar to that provided for 
under sections 6417 and 6418, applicable to taxpayers intending to 
claim the increased credit amount for satisfying the PWA requirements. 
Commenters alleged that since many of the credits covered by sections 
6417 and 6418 also contain PWA requirements, the language in sections 
6417 and 6418 requiring information or registration can be applied to 
require pre-filing registration of the intent to claim the increased 
credit amount.

[[Page 53192]]

    Section 6418(g)(1) provides that as a ``condition of, and prior to, 
any transfer of any portion of an eligible credit'' under section 6418, 
the Secretary of the Treasury or her delegate (Secretary) ``may require 
such information (including, in such form or manner as is determined 
appropriate by the Secretary, such information returns) or registration 
as the Secretary deems necessary for purposes of preventing 
duplication, fraud, improper payments, or excessive payments.'' Section 
6417(d)(5) provides the Secretary with similar discretion to implement 
a registration requirement. The authority to implement a pre-filing 
registration requirement provided in sections 6417 and 6418 is 
statutorily created and intended to address different underlying 
circumstances. Sections 6417(d)(5) and 6418(g) address the use of a 
registration system as a condition of and prior to certain events, 
specifically, prior to the amounts being treated as payments made by 
applicable entities or prior to transferring a credit.
    There is no analogous statutory language in section 45 or elsewhere 
in the Code related to the PWA requirements. Moreover, the registration 
requirements for sections 6417 and 6418 serve the specific purposes of 
preventing duplication, fraud, improper payments, or excessive 
payments. Those concerns are largely unique to the elective pay and 
credit transfer opportunities created by sections 6417 and 6418. In the 
context of sections 6417 and 6418, the IRS implemented the registration 
portal to prevent fraud and duplicate or improper payments, by 
providing the IRS with basic information that will facilitate 
processing and improve the administration of the credits. A pre-filing 
registration or reporting mechanism in the PWA context would not 
provide the IRS with actionable information for purposes of enforcing 
the PWA requirements. For these reasons, the comments requesting that 
the IRS establish a PWA registration system similar to that used for 
sections 6417 and 6418 are not adopted.
D. Other Comments Regarding Pre-Filing Activities and IRS Enforcement 
Procedures
1. Organizational Changes to the IRS and General Tax Administration
    Several commenters suggested that the final regulations implement 
organizational changes to the IRS. For example, one commenter 
recommended that the regulations create a dedicated office of labor 
standards enforcement to enforce the PWA provisions. An additional 
commenter requested that the Treasury Department establish a dedicated 
compliance and enforcement office. The commenter also encouraged the 
Treasury Department to review State requirements for disclosures, proof 
of payment, and affirmation, and adopt models that best effectuate 
compliance. One commenter suggested that the Treasury Department and 
the IRS create an inter-agency office with the DOL to facilitate the 
receipt of contemporaneous reporting from taxpayers.
    Another commenter suggested the creation of a digital platform to 
be used by taxpayers to submit PWA documentation that would be 
accessible by businesses, the DOL, and local apprenticeship programs. 
Several commenters recommended that the Treasury Department and the IRS 
partner with the DOL and applicable State agencies in the enforcement 
of PWA requirements. Additional commenters requested that the Treasury 
Department and the IRS establish formal partnerships with fair 
contracting organizations, labor unions, and other workers' rights 
organizations in order to expand the capacity to monitor jobsites. A 
commenter stated that such third-party partnerships--known as Joint 
Labor Compliance Monitoring Programs--have been successfully 
implemented across the country as a method of improving working 
conditions for workers and ensuring that projects are completed 
responsibly and on time.
    A few commenters suggested the final regulations prescribe specific 
actions regarding IRS enforcement, compliance, and general tax 
administration. For example, one commenter recommended that any IRS 
audit of increased credit amounts verify and cross-reference State 
labor materials to ensure prevailing wage and apprenticeship standards 
are met. A commenter stated that States such as California, Washington, 
and Wyoming have implemented State level apprenticeship utilization 
provisions and that the States have developed user friendly systems for 
contractors to report apprentice and journeyworker hours. At least one 
commenter also requested that the Treasury Department ensure that audit 
processes and other enforcement mechanisms are done in a transparent, 
accessible manner and with close engagement with other agencies. 
Several commenters provided recommendations regarding information that 
should be reported on IRS forms claiming the increased credit amount. A 
commenter suggested that the IRS implement a cross-withholding 
mechanism, modeled after that used by the DOL under the DBA, whereby a 
taxpayer engaged in two or more separate projects who is found to 
violate the PWA requirements on one project is then denied the 
increased credit amount with respect to any additional projects.
    Comments regarding the IRS's organizational structure, coordination 
with other agencies and States, how the IRS conducts audits, and 
changes to IRS forms are outside the scope of these final regulations. 
Therefore, the changes suggested by the comments are not adopted. In 
developing the Proposed Regulations and these final regulations, the 
Treasury Department and the IRS consulted extensively with the DOL and 
will continue to consult with the DOL as appropriate to assist in the 
administration of the PWA requirements.
2. Requests for Private Letter Rulings
    One commenter recommended that the IRS permit taxpayers to submit 
requests for Private Letter Rulings (PLRs) regarding compliance with 
the PWA requirements. Whenever appropriate in the interest of sound tax 
administration, it is the policy of the IRS to answer inquiries of 
individuals and organizations regarding their status for tax purposes 
and the tax effects of their acts or transactions, prior to the filing 
of returns or reports that are required by the revenue laws. Revenue 
Procedure 2024-1, 2024-01 I.R.B. 1, is updated each year and contains 
the general procedures for requests for PLRs. There are, however, 
certain areas in which the IRS will not issue rulings or determination 
letters, including areas in which the IRS is temporarily not issuing 
rulings or determination letters because those matters are under study. 
These no-rule issues are set forth in Revenue Procedure 2024-3, 2024-01 
I.R.B. 143, which is also updated annually. Issues pertaining to the 
application of the IRA currently are identified in Revenue Procedure 
2024-3 as matters under study by the IRS and thus are not currently 
subject to PLRs, but this position is subject to change. Updates to the 
no-rule issues are outside the scope of these final regulations.
3. Complaint Procedures for Underpayment of Applicable Prevailing Wage 
Rates and the Failure To Hire Qualified Apprentices
    The Proposed Regulations would have included whether the taxpayer 
had in place procedures whereby laborers and mechanics could report 
suspected failures to pay prevailing wages and/or suspected failures to 
classify workers correctly in accordance with the applicable wage 
determination to

[[Page 53193]]

appropriate personnel departments or managers without retaliation or 
other adverse action as a factor to be considered in the determination 
of intentional disregard.
    Many commenters requested that the final regulations prescribe the 
process through which a worker can complain about being underpaid. 
Commenters suggested that the process for complaints should be 
available to all interested parties, and that any person should be able 
to submit complaints to the government, preferably through the IRS 
website, without fear of retaliation by their employers or others. A 
commenter urged the IRS to develop and inform stakeholders and the 
public on complaint and enforcement procedures and provide contact 
information for the IRS office that will accept and investigate 
complaints. Another commenter recommended that the Treasury Department 
and the IRS create a complaint mechanism with both a telephone hotline 
and an online portal, and available in English and Spanish, to file 
complaints.
    Commenters acknowledged that unlike under the DBA, if the Treasury 
Department and the IRS are informed of violations or irregularities 
before the increased credit is claimed, the agencies would not be able 
to immediately assess fines or mandate that taxpayers issue corrective 
payments. A commenter acknowledged that there are limitations on the 
IRS's remedial authority, but suggested that the Treasury Department 
and the IRS have a compelling interest in instituting a complaint 
mechanism to obtain vital information that they can use in determining 
which taxpayers to audit. One commenter suggested permitting registered 
apprenticeship programs to petition the Treasury Department if they 
believe that a taxpayer is falsely claiming that the program is unable 
to meet the taxpayer's request for qualified apprentices.
    While the IRS takes information it receives regarding alleged tax 
violations very seriously, the comments requesting that the final 
regulations require a specific process regarding complaints are not 
adopted. Similar to the comments addressed in Section I.D.1. of this 
Summary of Comments and Explanation of Revisions regarding overall IRS 
administration, the comments concerning how the IRS should address 
reports of alleged tax violations are outside the scope of these final 
regulations. Additionally, the commenters overstate the usefulness of 
such information in the pre-filing context with respect to the PWA 
requirements. A laborer or mechanic might be paid wages at rates less 
than the applicable prevailing wage rates would require for such work, 
but that does not mean the laborer or mechanic was underpaid for 
purposes of section 45(b)(7)(A), unless and until a tax return claiming 
the increased credit amount is filed. The PWA requirements apply to the 
taxpayer, and the taxpayer must ensure that laborers and mechanics are 
paid wages at rates not less than the appliable prevailing wage rates 
for construction, alteration, or repair of a qualified facility. If a 
taxpayer, contractor, or subcontractor underpays a laborer or mechanic 
and does not subsequently correct the underpayment with the appropriate 
backpay and interest and pay the penalty amount, then the increased 
credit amount will be disallowed by the IRS.
    However, the Treasury Department and the IRS acknowledge the value 
in encouraging internal complaint and anti-retaliation procedures on 
facilities for which taxpayers acknowledge they anticipate claiming an 
increased credit amount by satisfying the PWA requirements. As 
discussed in Section VII.D.3. of this Summary of Comments and 
Explanation of Revisions, the final regulations include the existence 
of these procedures as a factor in determining whether a failure to 
satisfy the PWA requirements was due to intentional disregard. Further, 
these final regulations add as factors in determining intentional 
disregard whether the taxpayer posted information on how to contact the 
appropriate office to report suspected failures and whether in response 
to any complaint, the taxpayer investigated the complaint and took 
appropriate action to remedy the situation.
    Additional commenters proposed that the Treasury Department and the 
IRS clarify that workers who report PWA violations are protected by the 
anti-retaliation framework enacted under the Taxpayer First Act (26 
U.S.C. 7623 et seq.) (TFA). Commenters raised that section 7623(d)(1) 
states that no employer, contractor, or subcontractor may ``discharge, 
demote, suspend, threaten, harass, or in any other manner 
discriminate'' against an employee who has provided information or 
assisted in ``an investigation regarding underpayment of tax or any 
conduct which the employee reasonably believes constitutes a violation 
of the Internal Revenue laws or any provision of Federal law relating 
to tax fraud.'' Commenters stated that the TFA's anti-retaliation 
provisions under section 7623(d)(1) cover reporting to the Treasury 
Department, IRS, and related agencies, as well as internal reporting by 
a worker to their supervisors. Commenters emphasized that section 
7623(d)(2)(A) also provides the right to file a complaint with the 
Secretary of Labor with respect to any reprisals and provides for a 
private right of action in district court in the event that the 
Secretary of Labor has not issued a final decision within 180 days of 
the filing of the complaint.
    The application of section 7623, including the anti-retaliation 
provision enacted under the TFA, is outside the scope of these final 
regulations. However, whether laborers and mechanics were provided with 
a written notice of the rights conferred by the TFA is included as a 
factor the IRS will consider in determining if a failure to comply with 
the PWA requirements was due to intentional disregard. Additionally, 
IRS Form 3949-A, Information Referral, may be submitted by anyone with 
information about an alleged tax violation. The ability of any 
individual or organization to notify the IRS of specific and credible 
suspected tax violations serves as a powerful deterrent that supports 
voluntary compliance and has the potential to provide the IRS with 
information to identify and address noncompliance.
    Commenters acknowledge that at any point before the tax return is 
filed, it is within the taxpayer's discretion to refrain from claiming 
the increased credit amount and avoid the responsibility to make any 
related payments. Even so, commenters stated that the IRS is not 
limited in imposing conditions that the taxpayer must meet at the time 
of the construction, alteration, or repair to later claim the increased 
credit amount. The Treasury Department and the IRS agree that for those 
taxpayers that claim the increased credit amount on a return, the 
obligation to pay prevailing wages attaches as of the time that the 
work was performed. The final regulations prescribe correction 
procedures that apply on a retroactive basis, including interest 
accruing on any correction amounts from the date of the failure, to 
account for past failures that occurred at the time the construction, 
alteration, or repair work was performed.

II. PWA Transition Rule

    Under the BOC Exception in sections 30C, 45, 45Q, 45V, 45Y, and 
179D, taxpayers may claim the amount of the increased credit or 
deduction without satisfying the PWA requirements if construction (or 
installation with respect to section 179D) ``begins prior to the date 
that is 60 days after the Secretary publishes guidance with respect to 
the [PWA requirements].'' The Treasury Department and the IRS

[[Page 53194]]

published Notice 2022-61 on November 30, 2022, providing initial 
guidance with respect to the PWA requirements and starting the 60-day 
period described in those sections. Unless the One Megawatt Exception 
applies, taxpayers who do not meet the BOC Exception under these Code 
sections would need to satisfy the applicable PWA requirements to claim 
the increased amount of credit or deduction. Under sections 45L, 45U, 
45Z, and 48C, there is no BOC Exception or One Megawatt Exception, so 
taxpayers need to satisfy the applicable PWA requirements to claim the 
increased credit amount regardless of when construction began or how 
small the facility (or respective underlying creditable activity) may 
be.
    As enacted or amended by the IRA, the sections containing PWA 
provisions have various statutory effective dates. The PWA provisions 
in section 30C apply to property placed in service after December 31, 
2022.\11\ The PWA provisions in section 45 apply to facilities placed 
in service after December 31, 2021.\12\ The PWA provisions in section 
45L apply to dwelling units acquired after December 31, 2022.\13\ The 
PWA provisions in section 45Q apply to facilities or equipment placed 
in service after December 31, 2022.\14\ Section 45Y applies to 
facilities placed in service after December 31, 2024.\15\ In contrast, 
the effective dates of the PWA provisions in sections 45U, 45V, and 45Z 
are stated in relation to when the respective electricity, hydrogen, or 
transportation fuel is produced. Section 45U applies to electricity 
produced and sold after December 31, 2023, in taxable years beginning 
after such date.\16\ Section 45V applies to hydrogen produced after 
December 31, 2022.\17\ And Section 45Z applies to transportation fuel 
produced after December 31, 2024,\18\ but includes a special rule 
(described in Section IX.G. of this Summary of Comments and Explanation 
of Revisions) with respect to the Prevailing Wage Requirements if a 
facility is placed in service before January 1, 2025. The new 
allocation amounts available under section 48C(e) are effective on 
January 1, 2023.\19\ The amendments to section 179D apply to taxable 
years beginning after December 31, 2022.\20\

---------------------------------------------------------------------------

    Several commenters requested that the final regulations clarify 
whether the PWA requirements apply to work performed before January 29, 
2023, both with respect to Code sections with a BOC Exception and those 
without a BOC Exception. Commenters stated that it would be unfair to 
require taxpayers to comply with the PWA requirements with respect to 
these activities. Several commenters stated that the BOC Exception was 
intended to ensure that the PWA requirements are not applied 
retroactively and asked for a uniform rule applicable to all increased 
credit amount provisions that the PWA requirements do not apply before 
the BOC Exception trigger date. Other commenters asked that activities 
that occurred before the IRS issued Notice 2022-61 (November 30, 2022) 
be excluded from the PWA requirements. Some commenters stated that 
significant preliminary activities may have occurred prior to the 
enactment of the IRA, and they asked that the final regulations clarify 
that the PWA requirements do not apply to these activities, regardless 
of whether a BOC Exception may apply. One commenter suggested that the 
PWA requirements apply only after these final regulations are issued.
    The Treasury Department and the IRS have determined that given the 
complexity of the PWA requirements, the uncertainty regarding the 
potential retroactive effects of the PWA requirements, and the benefits 
to tax administration gained with consistency across the various Code 
sections containing PWA requirements, that a transition rule is 
appropriate.
    The final regulations provide that any work performed before 
January 29, 2023 (the date that is 60 days after the publication of 
Notice 2022-61) is not subject to the PWA requirements, regardless of 
whether there is an applicable BOC Exception. Thus, with respect to 
sections 45L, 45Z, and 48C, although there is no applicable BOC 
Exception and regardless of when construction began, taxpayers must 
only comply with the PWA requirements for the construction, alteration, 
or repair work (as applicable) occurring on or after January 29, 2023. 
Section 45U is not subject to the transition rule because, as described 
in Section IX.D. of this Summary of Comments and Explanation of 
Revisions, the Prevailing Wage Requirements of section 45U only apply 
to alterations or repairs of a qualified nuclear power facility that 
occur after December 31, 2023.
    The transition rule also applies for taxpayers that may initially 
satisfy the BOC Exception, but later fail to meet the BOC Exception 
(for example, failing to meet the Continuity Requirement). These 
taxpayers must satisfy the PWA requirements for construction, 
alteration, or repair (as applicable) that occurs on or after January 
29, 2023, but do not need to meet the PWA requirements for work that 
occurred prior to that date.

III. Beginning of Construction

A. Beginning of Construction Under the IRS Notices
    The IRS Notices describe two methods of establishing that 
construction of a facility has begun: (i) starting physical work of a 
significant nature (Physical Work Test), and (ii) paying or incurring 
five percent or more of the total cost of the facility (Five Percent 
Safe Harbor).
    Physical work of a significant nature can include both on-site and 
offsite work. Notice 2013-29 describes that in the case of a wind 
turbine, on-site physical work of a significant nature begins with the 
beginning of the excavation for the foundation, the setting of anchor 
bolts into the ground, or the pouring of the concrete pads of the 
foundation. Physical work of a significant nature does not include 
preliminary activities such as planning or designing, securing 
financing, exploring, researching, obtaining permits, licensing, 
conducting surveys, environmental and engineering studies, clearing a 
site, test drilling of a geothermal deposit, test drilling to determine 
soil condition, or excavation to change the contour of the land. Notice 
2013-29 explains that removal of existing turbines and towers is 
considered preliminary work and not physical work of a significant 
nature.
    Under the Five Percent Safe Harbor, if a taxpayer has paid or 
incurred five percent or more of the total cost of the facility and 
thereafter the taxpayer makes continuous effort to advance towards 
completion of the facility, then the construction of the facility will 
be considered to have begun. All costs properly included in the 
depreciable basis of the facility are taken into account but the cost 
of land or any property not integral to the facility is not included. 
Taxpayers can generally choose to structure their business affairs to 
meet either the Physical Work Test or the Five Percent Safe Harbor. 
However,

[[Page 53195]]

once a taxpayer meets either method, beginning of construction is 
established and a taxpayer may not alternate between methods.
B. Beginning of Construction and the BOC Exception Under Notice 2022-61 
and the Proposed Regulations
    Absent an exception, the PWA requirements apply with respect to the 
construction, alteration, or repair of a qualified facility. For 
purposes of the Prevailing Wage Requirements, section 45(b)(7)(A) 
provides that the taxpayer must ensure the payment of prevailing wages 
to laborers and mechanics employed in: (i) the ``construction'' of the 
qualified facility, and (ii) for ``the alteration or repair'' of the 
qualified facility during the 10-year period after the facility is 
placed in service. For purposes of the Apprenticeship Requirements, 
section 45(b)(8) provides that the taxpayer must satisfy the Labor 
Hours Requirement ``with respect to the construction of any qualified 
facility.''
    For purposes of determining when construction or installation 
begins under the BOC Exception, Notice 2022-61 incorporates by 
reference the IRS Notices. While Notice 2022-61 served to define the 
beginning of construction under the BOC Exception, Notice 2022-61 also 
states generally that it provides ``guidance for determining the 
beginning of construction'' under sections 30C, 45, 45Q, 45V, 45Y, 48, 
and 48E, and the beginning of installation under section 179D solely 
for purposes of section 179D(b)(3)(B)(i). The preamble to the Proposed 
Regulations explained that until further guidance is issued on 
determining when construction begins under the applicable Code 
sections, taxpayers may continue to rely on the guidance provided in 
Notice 2022-61 and principles similar to those under the IRS Notices 
for purposes of determining when construction begins.
    Section 3 of Notice 2022-61 contains guidance with respect to the 
Prevailing Wage Requirements. Section 3.03(4) of Notice 2022-61 
provides that ```construction, alteration, or repair' means 
`construction, prosecution, completion, or repair' as defined under 29 
CFR 5.2(j).'' In proposing rules under section 45(b)(7)(A), the 
Treasury Department and the IRS sought to incorporate those rules of 
the DBA regime relevant to the intent of the PWA requirements and 
useful for tax administration. Thus, consistent with Notice 2022-61, 
proposed Sec.  1.45-7(d)(2)(i) would have provided that the ``term 
construction, alteration, or repair generally means construction, 
prosecution, completion, or repair as defined in 29 CFR 5.2'' of the 
DBA regulations.
    In general, the DBA applies to contracts for construction, 
alteration or repair of public buildings and public works and requires 
payment of prevailing wages with respect to all mechanics and laborers 
employed directly on the site of the work.\21\ Under 29 CFR 5.2, 
construction, alteration, or repair is defined expansively to include 
all types of work done on a particular building or work at the site of 
the work, as defined in 29 CFR 5.2, by laborers and mechanics employed 
by a contractor or subcontractor. This work includes, but is not 
limited to, altering, remodeling, installing of items fabricated 
offsite, painting and decorating, manufacturing, or furnishing of 
materials, articles, and supplies or equipment on the site of the 
building or work, and certain demolition or removal activities.
---------------------------------------------------------------------------

    \21\ 40 U.S.C. 3142(a) and (c).
---------------------------------------------------------------------------

    Notice 2022-61 and proposed Sec.  1.45-7(d)(2)(i) would have 
defined construction, alteration, or repair by reference to the DBA. 
This means that the activity triggering the PWA requirements for a 
facility subject to the PWA requirements is determined by reference to 
activities that constitute construction under the DBA. A taxpayer must 
begin to satisfy the PWA requirements once construction, alteration, or 
repair activities occur if those activities are described in 29 CFR 
5.2. Under this definition, construction, alteration, or repair would 
mean all types of work performed at the location of the qualified 
facility.
C. Comments on Determining the Beginning of Construction for PWA 
Purposes
    Several commenters requested clarification concerning when the 
obligation to comply with the PWA requirements arises in the lifespan 
of a construction project apart from satisfying the BOC Exception, 
including what methods may be relied upon (the Physical Work Test or 
Five Percent Safe Harbor) and the Continuity Requirement. Another 
commenter suggested that the final regulations incorporate the tests 
from the IRS Notices into the final regulations. Commenters indicated 
that there is confusion regarding the precise scope of the PWA 
requirements because the word ``construction'' has different meanings 
under the DBA and the IRS Notices. One commenter stated that the 
preamble's use of both ``beginning of construction'' and ``start of 
construction'' was confusing.
    Several commenters requested clarification on when construction 
begins for purposes of the PWA requirements, noting that initial 
activities that constitute construction under 29 CFR 5.2 and would be 
subject to prevailing wage requirements under the DBA may not be the 
same activities that constitute the beginning of construction under the 
IRS Notices. A commenter also requested that the final regulations 
provide an exception from the PWA requirements for work subject to an 
agreement entered into prior to January 29, 2023, or give taxpayers who 
are a party to such agreements one year from the date the final 
regulations are published to comply with the PWA requirements. Further, 
commenters requested that the final regulations clarify that the 
beginning of construction is determined under existing tax principles 
and that preliminary activities, such as demolition or land clearing 
included under the DBA as work, do not count as the beginning of 
construction for PWA purposes. A commenter requested that the final 
regulations confirm that the end of construction corresponds to when an 
asset is placed in service and that activities afterward are not 
subject to the PWA requirements unless they are a covered alteration or 
repair.
    A commenter contended that the BOC Exception is anti-competitive 
and places an undue burden on new projects, as compared to projects 
that meet the BOC Exception, because projects meeting the BOC Exception 
will receive all the benefits of meeting Prevailing Wage Requirements 
without having to incur any of the associated costs. The commenter 
emphasized the importance of promoting a level playing field for all 
taxpayers interested in qualifying for increased credit amounts across 
clean energy industries.
D. Beginning of Construction for Purposes of the BOC Exception and the 
PWA Requirements in General
    The Treasury Department and the IRS understand commenters' concerns 
and the potential for confusion in determining the beginning of 
construction for purposes of the BOC Exception and the PWA 
requirements. While the Physical Work Test is very similar to the 
definition of construction under the DBA, certain preliminary 
activities are treated differently. Some activities constituting 
construction under the DBA definition would not constitute construction 
activities under the Physical Work Test. For instance, under the 
Physical Work Test, the demolition and removal of an existing structure 
would be considered a

[[Page 53196]]

preliminary activity, not the ``beginning of construction.'' However, 
under the DBA definition, the same activity would constitute 
construction. The Five Percent Safe Harbor, which has no equivalent 
under DBA, looks solely at incurred costs in determining whether 
construction has begun. Under all three tests, once construction begins 
a taxpayer must satisfy the PWA requirements with respect to all 
construction, alteration, or repair as defined in proposed Sec.  1.45-
7(d)(2) by reference to 29 CFR 5.2.
    The Treasury Department and the IRS have determined that using the 
DBA definition of construction to define the activities that mark the 
start of the obligation to comply with the PWA requirements for a 
qualified facility subject to the requirements provides a uniform rule 
across all the relevant Code sections. This is also consistent with the 
general approach in the Proposed Regulations and Section I.A. of this 
Summary of Comments and Explanation of Revisions of adopting DBA 
concepts when they are relevant to sound tax administration. Using the 
DBA definition of construction as the triggering activity provides a 
clear and uniform rule for taxpayers to determine when the obligation 
to comply with the PWA requirements begins. Thus, comments proposing 
use of the IRS Notices to determine the beginning of construction for 
purposes of the PWA requirements are not adopted. Providing a uniform 
rule that is generally applicable across all of the PWA provisions 
provides the necessary clarity sought by commenters. The final 
regulations provide that the activities that mark the start of the 
obligation to comply with the PWA requirements is any activity that 
constitutes construction (as defined in Sec.  1.45-7(d)(3)) of a 
qualified facility.
    Unless an exception applies, taxpayers are required to comply with 
the PWA requirements once a laborer or mechanic performs any work that 
is considered construction, alteration, or repair of the qualified 
facility (including work on the qualified facility that occurs at a 
secondary site). Thereafter, all work with respect to the construction 
(or alteration or repair), as defined in Sec.  1.45-7(d)(3) (by cross-
reference to 29 CFR 5.2), of the qualified facility is subject to the 
applicable PWA requirements. The beginning of construction, for 
purposes of satisfying the BOC Exception, will continue to be 
determined under the IRS Notices.
    In light of the differences between the tests, and because Notice 
2022-61 as well as the Proposed Regulations indicated that taxpayers 
could rely on the IRS Notices for determining when construction begins, 
the final regulations provide transition relief for taxpayers who 
applied the definitions in the IRS Notices for purposes of determining 
those activities that were considered construction, alteration, or 
repair of the facility subject to the PWA requirements in the initial 
stages of construction. The final regulations waive penalties for 
taxpayers who applied the IRS Notices for determining when the 
obligation to pay prevailing wages began, provided the taxpayer makes 
the appropriate correction payments to the impacted workers within 180 
days of the publication of the final regulations. As part of the 
transition relief, the final regulations also allow taxpayers to use 
the IRS Notices for determining when construction begins under section 
45(b)(8)(A) to determine the applicable percentage of labor hours 
performed by qualified apprentices required in satisfying the Labor 
Hours Requirement.

IV. One Megawatt Exception

    Under the One Megawatt Exception in section 45(b)(6)(B)(i), a 
qualified facility that has a maximum net output of less than one 
megawatt (as measured in alternating current) is eligible for the 
increased credit amount. The preamble to the Proposed Regulations would 
have provided that a qualified facility's nameplate capacity determines 
whether the facility meets the One Megawatt Exception. Similar 
exceptions apply for a qualified facility with a maximum net output of 
less than one megawatt (as measured in alternating current) under 
sections 45Y(a)(2)(B)(i) and 48E(a)(2)(A)(ii)(I); an energy project 
with a maximum net output of less than one megawatt of electrical (as 
measured in alternating current) or thermal energy under section 
48(a)(9)(B)(i); and energy storage technology with a capacity of less 
than one megawatt under section 48E(a)(2)(B)(ii)(I).
    Proposed Sec.  1.45-6(c) would have provided that nameplate 
capacity for an electrical generating unit means the maximum electrical 
generating output in megawatts that the unit is capable of producing on 
a steady state basis and during continuous operation under standard 
conditions, as measured by the manufacturer and consistent with the 
definition provided in 40 CFR 96.202. If applicable, the International 
Standard Organization (ISO) conditions are used to measure the maximum 
electrical generating output or usable energy capacity.
    Commenters stated that the term ``maximum net output'' is ambiguous 
and that no method is provided for determining such output. A few 
commenters also supported the Proposed Regulation's definition of 
maximum net output and suggested carrying the nameplate capacity 
definition of maximum net output forward into its final rule. One 
commenter raised that for inverter-based resources, like solar and 
storage facilities, maximum net output could be determined at different 
stages. For such facilities, the commenter recommended clarifying that 
only post-inverter maximum electrical generating output qualifies as 
maximum net output. The final regulations do not adopt these changes 
because the definition in proposed Sec.  1.45-6(c) contained testing 
methodologies and conditions and the statute already requires the 
measurement be in alternating current. The final regulations adopt the 
definition without change.
    Another commenter suggested clarifying when multiple energy 
projects constitute a single facility for purposes of the One Megawatt 
Exception under section 45. One commenter suggested adopting the eight 
factors of a single project determination listed in Notice 2013-29 and 
Notice 2018-59, to determine when multiple energy projects constitute a 
single facility for purposes of the One Megawatt Exception. The 
commenter stated that it could be difficult, such as for solar arrays 
constructed on multiple buildings, to determine when multiple projects 
may constitute a single facility. Another commenter stated that 
taxpayers should not be permitted to subdivide projects and 
construction contracts in an effort to evade the Prevailing Wage 
Requirements using the One Megawatt Exception. The commenter stated 
that to prevent taxpayers from manipulating the One Megawatt Exception, 
the Treasury Department should evaluate whether facilities will be 
using the same transmission lines or connecting to the same powerhouse. 
One commenter recommended using certain factors, including ownership, 
proximity, and connection to transmission lines or powerhouse, to 
determine whether multiple energy projects may be deemed to constitute 
one facility.
    The definition of a qualified facility, energy project, or energy 
storage technology under the respective Code section controls for 
purposes of the One Megawatt Exception. Therefore, the definition of 
qualified facility under section 45 governs for purposes of the One 
Megawatt Exception under section 45(b)(6)(B)(i). Accordingly, the 
application of the aggregation principles issued under Notice 2013-29 
and Notice

[[Page 53197]]

2018-59 is outside the scope of these final regulations. Further, the 
Section 48 Proposed Regulations would provide guidance for taxpayers 
regarding the definition of an energy project. The Section 48 Proposed 
Regulations would provide rules for purposes of the One Megawatt 
Exception as well as other IRA bonus provisions for domestic content 
and energy communities. As noted previously, comments pertaining to the 
48 Proposed Regulations will be addressed in a future Treasury 
decision. The applicable scope of the PWA requirements is further 
discussed in Section VI. of this Summary of Comments and Explanation of 
Revisions.

V. Application to the Taxpayer

A. Definition of Taxpayer, Contractor, and Subcontractor
    Generally, the Proposed Regulations would have defined the term 
taxpayer to mean any taxpayer as defined in section 7701(a)(14), 
including applicable entities described in section 6417(d)(1)(A). This 
generally will be the entity that claims the credit (as increased under 
section 45(b)(6)) or makes an election under section 6417 with respect 
to such credit amount on a Federal income tax return.
    The Proposed Regulations would have provided that in order to earn 
the increased credit amount under section 45(b)(6) by satisfying the 
PWA requirements, the taxpayer would be solely responsible for: (i) 
ensuring that the relevant laborers and mechanics are paid wages not 
less than the prevailing rate whether employed directly by the 
taxpayer, or by a contractor, or a subcontractor, and (ii) ensuring 
that the Apprenticeship Requirements are satisfied. The Proposed 
Regulations also would have provided that the taxpayer would be solely 
responsible for the PWA recordkeeping requirements, the correction and 
penalty provisions under the Prevailing Wage Requirements, and the Good 
Faith Effort Exception and Apprenticeship Cure Provision under the 
Apprenticeship Requirements. However, nothing in the Proposed 
Regulations was intended to supersede requirements that might otherwise 
apply to a taxpayer, contractor, or subcontractor under State or 
Federal law.
    Commenters requested guidance concerning whether the taxpayer is 
responsible for ensuring the compliance with the PWA requirements by 
contractors and subcontractors if the taxpayer may not be in privity of 
contract with all contractors and subcontractors. Commenters noted that 
proposed Sec.  1.45-7(d)(3) would have defined a contractor as any 
person that enters into a contract with the taxpayer for the 
construction, alteration, or repair of a qualified facility. However, 
commenters stated that the taxpayer is not always in privity of 
contract with each contractor and subcontractor. Similarly, another 
commenter suggested that the definition of contractor be revised to 
address situations in which the taxpayer is not in privity of contract 
with the contractors, because the sponsor or developer of the facility 
assumes responsibility for construction of the facility. The final 
regulations clarify that the definition of contractor applies to those 
situations. Additionally, a commenter stated that DOL guidance under 29 
CFR 5.5(a)(6) provides that prime contractors have the responsibility 
for the compliance of all the subcontractors on a covered prime 
contract, whereas the Proposed Regulations state that the taxpayer is 
solely responsible for PWA compliance. The final regulations retain the 
requirements in the Proposed Regulations that the taxpayer is solely 
responsible for the PWA requirements, including ensuring that the 
relevant laborers and mechanics are paid wages at rates not less than 
the prevailing rates whether employed directly by the taxpayer, a 
contractor, or a subcontractor and ensuring that the Apprenticeship 
Requirements are satisfied.
    A commenter suggested that the final regulations adopt a safe 
harbor allowing taxpayers to avoid corrections and penalty payments if 
the taxpayer contracted with a third party to ensure compliance with 
relevant PWA requirements. Section 45(b)(7)(A) requires that the 
taxpayer ensures that laborers and mechanics are paid wages at rates 
not less than the applicable prevailing wage rates with respect to the 
construction, alteration, or repair of a qualified facility and under 
section 45(b)(8)(A), that the required number of labor hours with 
respect to the construction of a qualified facility are performed by 
qualified apprentices. The burden to ensure that these requirements are 
met falls with the taxpayer. The final regulations do not adopt the 
suggestion to incorporate a safe harbor, but the penalty waiver in 
Sec.  1.45-7(c)(6) and described in Section VII.D.4. of this Summary of 
Comments and Explanation of Revisions provides an appropriately limited 
exception to corrections and penalty payments in the case of 
inadvertent errors.
    Similarly, one commenter requested that the final regulations 
permit contractors or subcontractors to make corrective payments on 
behalf of the taxpayer directly to laborers or mechanics. The 
correction and penalty provision in section 45(b)(7)(B)(i) requires 
that the taxpayer makes payment to the laborer or mechanic of the 
correction amount. The Treasury Department and the IRS appreciate 
commenters' suggestions to encourage methods that result in prompt 
correction payments to laborers and mechanics. Although the statute 
requires that the correction payment be made by the taxpayer to the 
laborers and mechanics, it does not prescribe the method by which the 
taxpayer must make payment. The final regulations similarly do not 
prescribe a specific method of payment and adopt the proposed rule 
without change. Regardless of how payments are made, taxpayers must 
maintain records demonstrating when and how correction payments were 
made.
    A few commenters suggested that the final regulations clarify the 
requirement that the taxpayer ensure that all laborers and mechanics 
employed by the taxpayer, or any contractor or subcontractor, are paid 
wages at rates not less than the prevailing rates applies to all 
subcontractors. Specifically, taxpayers stated that the DBA definition 
of subcontractor indicates that a subcontractor includes subcontractors 
of any tier, and suggested that the final regulations use the same term 
in the definition of subcontractor. The definition of subcontractor in 
the final regulations clarifies that the requirement applies to all 
subcontractors, including those who contract with other subcontractors.
    Another commenter suggested that the use of subcontractor labor 
providers, such as labor brokers, should be explicitly discouraged 
because of the risk of fraud. This suggestion is overbroad and 
inconsistent with the plain language of section 45, which anticipates 
the use of contractors and subcontractors. This suggestion is not 
adopted.
B. Transferability Pursuant to Section 6418
    The Treasury Department and the IRS requested comments on the 
application of the PWA correction and penalty provisions in the context 
of transferred credits. The credit available under section 45, 
including the increased credit amount available under section 45(b)(6), 
is an eligible credit subject to section 6418. Proposed Sec.  1.45-
7(c)(1)(iv) and proposed Sec.  1.45-8(e)(2)(iv) would have provided 
that to the extent an eligible taxpayer, as defined in section 
6418(f)(2), has determined an increased

[[Page 53198]]

credit amount under section 45(b)(6) and transferred such increased 
credit amount as part of a specified credit portion pursuant to section 
6418(a), the obligation to make correction and penalty payments under 
proposed Sec.  1.45-7(c)(1)(i) and (ii) and the penalty payment under 
proposed Sec.  1.45-8(e)(2)(i) remains with the eligible taxpayer. No 
commenters disagreed with having the eligible taxpayer remain 
responsible for the PWA correction and penalty provisions under 
proposed Sec.  1.45-7(c)(1)(iv) or proposed Sec.  1.45-8(e)(2)(iv). 
Consequently, these final regulations adopt proposed Sec.  1.45-
7(c)(1)(iv) and proposed Sec.  1.45-8(e)(2)(iv) without change. 
However, commenters raised other issues related to the PWA provisions 
in the context of a transfer pursuant to section 6418, which are 
addressed in the following paragraphs.
    Under proposed Sec.  1.45-7(c)(1)(iv) and proposed Sec.  1.45-
8(e)(2)(iv), to the extent an eligible taxpayer transfers a credit 
increased pursuant to the PWA requirements, the obligation to satisfy 
the PWA requirements becomes binding upon the earlier of the filing of 
the eligible taxpayer's return for the taxable year for which the 
specified credit portion is determined with respect to the eligible 
taxpayer or the filing of the return of the transferee taxpayer for the 
year in which the specified credit portion is taken into account. One 
commenter stated that if the eligible taxpayer is a calendar year 
taxpayer and the transferee taxpayer is a fiscal year taxpayer, then 
the ability of the eligible taxpayer to make any correction or penalty 
payments may be shortened.
    Section 6418 and the final regulations thereunder (TD 9993) 
published in the Federal Register (89 FR 34770) on April 30, 2024 (6418 
Final Regulations), provide that the transferee taxpayer takes into 
account the transferred credit in the first taxable year ending on or 
after the taxable year of the eligible taxpayer with respect to which 
the credit was determined. Consequently, if an eligible taxpayer has a 
calendar year taxable year and the transferee taxpayer has a fiscal 
year taxable year, the transferee taxpayer's return due date generally 
will be after the eligible taxpayer's return due date. In the event a 
transferee taxpayer files a return that claims an increased credit 
amount transferred from an eligible taxpayer prior to the eligible 
taxpayer filing its return, the obligation to have satisfied the PWA 
requirements becomes legally binding upon the filing of the return of 
the transferee taxpayer. However, in any scenario, eligible taxpayers 
will have the ability to make any required correction and penalty 
payments as provided under section 45(b)(7)(B)(iv), which allows such 
payments to be made within 180 days of a determination by the IRS with 
respect to a failure regarding prevailing wages, or under section 
45(b)(8)(D)(i) with respect to apprenticeship failures. The transferee 
taxpayer filing its tax return before the eligible taxpayer does not 
shorten this period. Further, the eligible taxpayer and the transferee 
taxpayer are required to attach a transfer election statement 
describing specific details relating to the transaction, including any 
increased credit amounts, and prior to filing any tax returns, the 
parties should have verified eligibility under the PWA provisions. 
Therefore, the Treasury Department and the IRS did not revise the 
proposed rule in these final regulations.
    Commenters recommended specifying that if a credit amount increased 
pursuant to the PWA requirements is transferred to multiple transferee 
taxpayers, the responsibility to make correction and penalty payments 
remains indivisible with the eligible taxpayer. This comment is 
consistent with the Proposed Regulations, which did not distinguish 
between situations with one or multiple transferee taxpayers. These 
final regulations adopt the proposed rule without change.
    One commenter recommended that transferee taxpayers being 
transferred an eligible credit increased pursuant to the PWA 
requirements should be secondarily liable for any correction and 
penalty payments. The commenter stated that if the transferee taxpayer 
is not secondarily liable, then the amounts may not be paid because the 
eligible taxpayer will have already received the consideration from the 
transfer of the tax credit. Further, the commenter suggested that the 
transferee taxpayer should be required to keep the same records as the 
eligible taxpayer in order to demonstrate reasonable cause with respect 
to excessive credit transfers and should also be required to 
contractually bind the eligible taxpayer to meet the PWA requirements, 
indemnifying the transferee taxpayer for any such payments it is 
secondarily required to make.
    The Treasury Department and the IRS do not adopt these changes. As 
explained in the preamble to the Proposed Regulations, credit amounts 
increased pursuant to the PWA requirements are part of determining the 
eligible credit by the eligible taxpayer. The 6418 Final Regulations 
confirm that any specified credit portion is a proportionate share of 
the entire eligible credit, including any increases pursuant to the PWA 
requirements. Therefore, it is part of the eligible taxpayer's 
responsibility to satisfy the PWA requirements and requiring the 
eligible taxpayer to make any correction or penalty payments remains 
appropriate. Requiring the transferee taxpayer to be secondarily liable 
may inappropriately shift the responsibility to satisfy the PWA 
requirements. It is the responsibility of the transferee taxpayer under 
section 6418 and the 6418 Final Regulations to perform due diligence to 
show reasonable cause in the event of an excessive credit transfer, but 
changes to those rules are outside the scope of these final 
regulations. Additionally, specific recordkeeping requirements for the 
eligible taxpayer and transferee taxpayer(s) under section 6418 are 
addressed in the 6418 Final Regulations and are outside the scope of 
these final regulations.
    A commenter recommended that a transferee taxpayer should be able 
to rely on assurances from the eligible taxpayer that all covered work 
was performed under the terms of a qualifying project labor agreement 
(discussed in Section V.D. of this Summary of Comments and Explanation 
of Revisions) to demonstrate ``reasonable cause'' in the context of an 
excessive credit transfer relating to the PWA requirements. These final 
regulations do not adopt this suggestion as excessive credit transfers 
are outside the scope of these final regulations and are addressed in 
the 6418 Final Regulations.
C. Application to Indian Tribal Governments and the Tennessee Valley 
Authority
    The preamble to the Proposed Regulations explained that the 
statutory language of the IRA does not reflect any intent to include 
exceptions from the PWA requirements other than the BOC Exception and 
the One Megawatt Exception. Consequently, the Proposed Regulations 
would not have included a rule that would exempt Indian Tribal 
governments or the Tennessee Valley Authority (TVA) from the PWA 
requirements. The Treasury Department and the IRS requested comments on 
the need for any exceptions, including for Indian Tribal governments or 
the TVA, from the PWA requirements in addition to those expressly 
described in the statute.
1. Indian Tribal Governments
    In accordance with Executive Order 13175 (Consultation and 
Coordination with Indian Tribal governments) and Executive Order 14112 
(Reforming Federal Funding and Support for Tribal

[[Page 53199]]

Nations To Better Embrace Our Trust Responsibilities and Promote the 
Next Era of Tribal Self-Determination), the Treasury Department and the 
IRS support the right of Indian Tribes to self-govern and recognize 
that Indian Tribes exercise inherent sovereign powers over their 
members and territory. The Treasury Department and the IRS are guided 
by the fundamental principles in Executive Orders 13175 and 14112. 
Under those principles, the Treasury Department and the IRS have an 
obligation to consider the concerns raised by Tribes and, to the extent 
permitted by law, address those concerns in the final regulations.
    On September 25, 2023, the Treasury Department and the IRS held a 
Tribal consultation with Tribal leaders requesting assistance in 
addressing questions related to the PWA requirements in the Proposed 
Regulations. Through consultation and in response to the Proposed 
Regulations, the Treasury Department and the IRS received numerous 
comments regarding an exception to the PWA requirements for projects 
constructed by Indian Tribal governments. A number of commenters 
recommended that Indian Tribal governments should not be exempted from 
the PWA requirements and cited to the lack of statutory basis to grant 
an exception. In contrast, other commenters supported an exception to 
the PWA requirements for Indian Tribal governments.
A. Prevailing Wage Requirements and Indian Tribal Governments
    With respect to the Prevailing Wage Requirements, commenters 
suggested that requiring projects located on Tribal lands to comply 
with wage standards set by the DOL undermines Tribal sovereignty. Some 
commenters stated that the DOL provides an exception from the DOL 
prevailing wage rates for work done by Indian Tribal governments using 
their own employees, and advocated that the final regulations, at a 
minimum, contain a similar rule under the IRA.
    Commenters also stated that the DOL prevailing wage rates often are 
defined at the county level, which may include higher cost urban areas 
and could negatively impact projects on Tribal lands that often occur 
in the rural portions of such counties. These commenters stated that 
complying with wage standards set by the DOL for IRA projects could 
place additional administrative burdens on Tribes by requiring Tribes 
to administer two sets of prevailing wages (DOL prevailing wage 
standards for IRA projects and Tribal prevailing wage standards for 
other projects). As an alternative to permitting Indian Tribal 
governments to set their own prevailing wage rates for IRA projects, 
commenters suggested defining the term locality to include Tribal lands 
as a separate category to allow Tribes to submit a request to the DOL 
for a supplemental wage determination for that specific Tribal 
locality.
    With respect to the Prevailing Wage Requirements, the Treasury 
Department and the IRS continue to understand the statutory language of 
the Code as not reflecting an intent to entirely exempt Indian Tribal 
governments from the PWA requirements. The statutory language also does 
not reflect an intent to allow Indian Tribal governments to substitute 
their own prevailing wage rates for those generally required under the 
DBA.
    However, in accordance with Executive Order 14112, the final 
regulations provide two special rules that apply to Indian Tribal 
governments (including a subdivision, agency, or instrumentality of an 
Indian Tribal government). First, the final regulations provide that an 
Indian Tribal government, as defined in section 30D(g)(9) of the Code, 
is excepted from the Prevailing Wage Requirements under the IRA with 
respect to laborers and mechanics that are employees, within the 
meaning of section 3121(d)(2), of the Indian Tribal government. This 
rule also applies to joint ownership arrangements that involve an 
Indian Tribal government (including a subdivision, agency, or 
instrumentality of an Indian Tribal government), but only with respect 
to the employees, within the meaning of section 3121(d)(2), of the 
Indian Tribal government. As stated in some comments from Tribes, the 
DOL provides an exception from the DOL prevailing wage rates for work 
done by Tribal governments using their own employees. Specifically, 
under the DBA, a government agency may perform construction work in-
house with its own employees rather than contract out the work. Work 
performed by these employees generally is not subject to the DBA 
requirements because governmental agencies are not considered 
contractors or subcontractors under the DBA. This is known as the force 
account exception. The DOL has explained that in cases in which an 
Indian Tribal government performs work with its own employees, the 
force account exception to the DBA generally applies and the Tribal 
government is not required to pay DOL-determined prevailing wages for 
work done by its own employees. Tribes historically have relied on this 
exception. Under these final regulations, Tribes may continue that 
practice for purposes of the Prevailing Wage Requirements under the 
IRA.
    Second, the Treasury Department and the IRS recognize that Tribal 
lands generally are not coextensive with a single geographic area for 
which the DOL may have made an applicable wage determination. Comments 
from Tribes requested that the final regulations define the term 
``locality'' to include Tribal lands as a separate category to allow 
Tribes to submit a request to the DOL for a supplemental wage 
determination for specified Tribal lands. However, defining locality in 
this way would require that the DOL establish a new administrative 
process to implement a unique wage determination for Tribal lands; that 
process is outside of the authority of the Treasury Department and the 
IRS. Thus, these final regulations do not change the definition of 
locality to include Tribal lands as a separate category.
    However, recognizing that Tribal lands are sovereign territories 
that may encompass or overlap with numerous geographic areas, the final 
regulations provide a special rule for Indian Tribal governments that 
perform construction, alteration, or repair of a facility on Indian 
land, as that term is defined in 25 U.S.C. 3501(2). Specifically, if 
the Indian land encompasses or overlaps more than one geographic area 
with respect to which the DOL has made an applicable wage 
determination, then the Indian Tribal government may choose the 
applicable wage determination for any one of those geographical areas 
and apply that applicable wage determination for work performed on any 
qualified facility that is located on the Indian land. If the Indian 
Tribal government chooses to use this alternative applicable wage 
determination, it must maintain and preserve records sufficient to 
document the applicable prevailing wage for each laborer, contractor, 
or subcontractor with respect to each qualified facility on Indian 
land. This rule applies to a qualified facility that is subject to 
joint ownership arrangements that involve an Indian Tribal government 
(including a subdivision, agency, or instrumentality of an Indian 
Tribal government). This rule is intended to ease the administrative 
burden on Indian Tribal governments because they can use a single 
applicable wage determination for all projects on Indian land.

[[Page 53200]]

b. Apprenticeship Requirements and Indian Tribal Governments
    Regarding the Apprenticeship Requirements, some commenters 
supported an exception for Indian Tribal governments and stated that 
Tribes may have limited access to registered apprenticeship programs. 
These commenters stated that Tribal members may face burdens associated 
with participating in existing State registered apprenticeship programs 
that are located many miles away. A commenter requested clarification 
regarding whether Tribes, like States, have the sovereign and 
jurisdictional authority to develop and certify their own 
apprenticeship programs rather than being required to use the DOL 
approval process. The same commenter requested that the Treasury 
Department and the IRS review and report on any barriers that may 
disproportionately prevent Tribes from fulfilling the Apprenticeship 
Requirements. Commenters suggested that if Indian Tribal governments do 
not have authority to certify their own programs, then the 
Apprenticeship Requirements could force Tribal governments to rely on 
State or Federal apprenticeship programs, which may frustrate Indian 
Tribal governments' efforts to develop their Tribal workforce.
    Commenters supporting an Indian Tribal government exception to the 
Apprenticeship Requirements also stated that the Good Faith Effort 
Exception places too much onus on Indian Tribal governments to obtain 
qualified apprentices. These commenters suggested that Indian Tribal 
governments could need to submit multiple requests to multiple 
apprenticeship programs and that Indian Tribal governments could need 
to search across non-Tribal areas to meet the Good Faith Effort 
Exception. These commenters suggested that the statute did not require 
this level of apprenticeship coverage. Commenters also stated that the 
Good Faith Effort Exception may not be met if a registered 
apprenticeship program can meet some, but not all of requests for 
qualified apprentices, and suggested that the Good Faith Effort 
Exception should be satisfied if a registered apprenticeship program 
could not fulfill more than 50 percent of a taxpayer, contractor, or 
subcontractor's request. These commenters also suggested that the Good 
Faith Effort Exception should be satisfied if a local registered 
apprenticeship program cannot provide more than 50 percent of the 
requested qualified apprentices. Commenters also stated that the Good 
Faith Effort Exception is unreasonable for Indian Tribal governments in 
rural areas because of the limited access to registered apprenticeship 
programs. Finally, another commenter suggested creating a database for 
taxpayers to find Tribal apprenticeship programs within their State.
    With respect to the Apprenticeship Requirements, the Treasury 
Department and the IRS recognize that there may be a limited number of 
registered apprenticeship programs with an area of operation that 
includes the geographic location of a facility located on Tribal lands. 
As explained in Section VIII.B.1.f. of this Summary of Comments and 
Explanation of Revisions, the final regulations clarify the scope of 
the Good Faith Effort Exception with respect to situations in which 
only part of the request is denied. The final regulations confirm that 
if there is no registered apprenticeship program with a geographic area 
of operation that includes the location of the facility, taxpayers will 
be deemed to satisfy the Good Faith Effort Exception for the qualified 
apprentices they (or the contractor or subcontractor) would have 
requested for that occupation and location.
    Indian Tribal governments may also consider sponsoring their own 
registered apprenticeship programs to satisfy the Apprenticeship 
Requirements. The National Apprenticeship Act (NAA) of 1937 (29 U.S.C. 
50) authorizes the Secretary of Labor to formulate and promote the 
furtherance of labor standards necessary to safeguard the welfare of 
apprentices. The Treasury Department and the IRS have consulted with 
the DOL OA and understand based on that discussion that although 
neither the text of the NAA, nor the content of the NAA's implementing 
regulations at 29 CFR parts 29 and 30, explicitly addresses Indian 
Tribes, Indian Tribal governments may sponsor registered apprenticeship 
programs and obtain registration of such a Tribal apprenticeship 
program by a State or Federal governmental agency that has been 
designated for that purpose.
    Federal apprenticeship regulations (see 29 CFR part 29) authorize 
the DOL to grant recognition, for Federal purposes, to State 
apprenticeship agencies for the purpose of registering and overseeing 
apprenticeship programs that operate within their respective 
jurisdictions, provided that such State apprenticeship agencies operate 
in accordance with the minimum standards for State apprenticeship 
agencies that are established by Federal apprenticeship regulations. 
Nevertheless, the DOL retains the authority under Federal 
apprenticeship regulations to register any apprenticeship program that 
operates within the territory of the United States, provided that, as a 
general matter, the sponsor's proposed program and standards of 
apprenticeship satisfy the minimum requirements stipulated in 29 CFR 
parts 29 and 30.
    Accordingly, Indian Tribal governments may register their own 
apprenticeship programs through the DOL OA or with a recognized State 
apprenticeship agency. In recognition of the unique trust and treaty 
responsibilities of the Federal Government to Tribal Nations, respect 
for Tribal sovereignty, and the nation-to-nation relationship between 
the Federal Government and Indian Tribes, Indian Tribal governments 
(including a subdivision, agency, or instrumentality of the Indian 
Tribal government) are encouraged but not required to register programs 
with the DOL OA. Taxpayers, contractors, and subcontractors can find 
more information on guidance issued by the DOL OA at <a href="https://www.apprenticeship.gov/about-us/legislation-regulations-guidance">https://www.apprenticeship.gov/about-us/legislation-regulations-guidance</a>. For 
an updated map depicting the most recent information regarding 
registration agencies between the DOL OA and State apprenticeship 
agencies, please visit: <a href="https://www.apprenticeship.gov/about-us/apprenticeship-system">https://www.apprenticeship.gov/about-us/apprenticeship-system</a>.
2. Tennessee Valley Authority
    Several commenters requested that the final regulations not provide 
an exception from the PWA requirements for the TVA, citing the lack of 
statutory authority for such an exception. The Treasury Department and 
the IRS agree. The final regulations do not create an exception to the 
PWA requirements for the TVA.
D. Project Labor Agreements
    The preamble to the Proposed Regulations explained that pre-hire 
project labor agreements (PLAs) may be used to incentivize stronger 
labor standards and worker protections in the types of construction 
projects for which taxpayers may seek the increased credit amount, and 
having a PLA in place may help ensure compliance with PWA requirements. 
For these reasons, the Proposed Regulations would have provided that 
the penalty payment requirements would not apply with respect to a 
laborer or mechanic employed under a ``qualifying project labor 
agreement'' if any correction payment owed to the laborer or mechanic 
is paid on or before a return is filed claiming an increased credit

[[Page 53201]]

amount. The Proposed Regulations would have defined qualifying project 
labor agreement as ``a pre-hire collective bargaining agreement with 
one or more labor organizations that establishes the terms and 
conditions of employment for a specific construction project.'' 
Proposed Sec.  1.45-7(c)(6)(ii) would have provided that in order to be 
considered a qualifying project labor agreement, such agreement must at 
a minimum: (i) bind all contractors and subcontractors on the 
construction project through the inclusion of appropriate 
specifications in all relevant solicitation provisions and contract 
documents; (ii) contain guarantees against strikes, lockouts, and 
similar job disruptions; (iii) set forth effective, prompt, and 
mutually binding procedures for resolving labor disputes arising during 
the term of the project labor agreement; (iv) contain provisions to pay 
prevailing wages; (v) contain provisions for referring and using 
qualified apprentices consistent with section 45(b)(8)(A) through (C) 
and guidance issued thereunder; and (vi) be a collective bargaining 
agreement with one or more labor organizations (as defined in 29 U.S.C. 
152(5)) of which building and construction employees are members, as 
described in 29 U.S.C. 158(f).
    The Treasury Department and the IRS requested comments on the 
proposed treatment of PLAs, other ways taxpayers might use PLAs to meet 
the PWA requirements, and the proposed definition of a qualifying 
project labor agreement. Several comments were received addressing the 
proposed treatment of PLAs under the Proposed Regulations.
    Several commenters asserted that the Treasury Department and the 
IRS should not exempt taxpayers using PLAs from the penalty payment 
requirements. Commenters stated that the proposed rule violates the 
plain text of the IRA, which includes no PLA provision and does not 
authorize the waiver of intentional violations and additional penalties 
based on a clean energy project developer's inclusion of a PLA 
requirement in its solicitation for construction services. Several 
commenters stated that the IRS should not incentivize or coerce the use 
of PLAs through a penalty waiver or other benefit. Commenters suggested 
that PLAs will discourage taxpayers from using their existing 
workforce. Commenters were also concerned with PLAs increasing the cost 
of construction. Another commenter suggested that PLA mandates would 
likely lead to a decrease in hiring of local, minority, women, veteran, 
and other potentially disadvantaged groups. Other commenters stated 
that encouraging labor unions was not the intent of the IRA. A 
commenter also asserted that PLAs force contractors to replace 
employees with workers from unions, undermine workforce development 
strategies, force contractors to follow inefficient union work rules, 
expose workers to wage theft, and expose employers to multiemployer 
pension plan liabilities. The commenter also asserted that PLA mandates 
force employees to join a union and pay dues and discourage competition 
from nonunionized contractors. The commenter claimed that strikes have 
occurred on PLA projects and that PLAs will not improve efficiency in 
terms of safety, quality, or project delivery.
    In contrast, other commenters asserted that PLAs help ensure 
compliance with the PWA requirements. Several commenters requested that 
taxpayers certifying that construction of a facility is subject to a 
PLA or a collective bargaining agreement should be entitled to a safe 
harbor or a rebuttable presumption of compliance with the PWA 
requirements. Commenters asserted that such a presumption would be 
warranted because PLAs provide assurances of compliance and contractors 
operating under PLAs typically pay wages at rates that are at or above 
the prevailing wage rates. At least one commenter suggested that the 
final regulations should clarify that a taxpayer is deemed to have 
satisfied the PWA requirements, including recordkeeping requirements, 
if the taxpayer can provide proof of a valid PLA.
    Other commenters suggested that the final regulations create a two-
tier compliance structure under which participants with PLAs are 
awarded a presumption of compliance on several requirements (or limited 
review by the IRS on examination) while other taxpayers not 
participating in PLAs should be subjected to heightened scrutiny by the 
IRS. A commenter stated that, in the absence of a PLA, violations of 
PWA requirements would be more prevalent. Therefore, the commenter 
suggested increasing the oversight and noncompliance penalties for non-
PLA projects, mandating robust recordkeeping requirements for non-PLA 
projects (including the filing of certain documents with the DOL), and 
creating flexible ratio requirements for PLA projects. Another 
commenter suggested that taxpayers who are parties to both a collective 
bargaining agreement and PLA should automatically qualify for the Good 
Faith Effort Exception.
    Some commenters stated that PLAs can help taxpayers ensure payment 
of prevailing wages, because PLAs will: (i) require employers to 
provide workers with notice of their pay rates; (ii) include 
integrated, enforceable grievance and dispute resolution procedures; 
and (iii) be administered and enforced by unions that are parties to 
PLAs. Another commenter stated that PLAs typically establish payments 
to third-party benefit trusts, and that IRS research shows that third-
party information can help promote tax compliance. Additionally, 
another commenter stated that entitling taxpayers to a presumption of 
compliance if their construction project is subject to a PLA would 
mitigate enforcement work and therefore preserve IRS resources.
    Further, several commenters stated that PLAs help promote the IRA's 
goals by improving efficiency, coordination, and consistency; reducing 
administrative costs; preventing increased costs and project delays; 
providing a steady supply of highly skilled labor; and preventing labor 
disputes. Some commenters recommended that taxpayers implementing PLAs 
be exempt from a determination that they intentionally disregarded the 
PWA requirements.
    The Treasury Department and the IRS disagree with commenters 
asserting that the Proposed Regulation's provisions regarding 
qualifying project labor agreements are unwarranted, coercive, and 
would increase costs. For example, studies show that PLAs in general do 
not lead to a statistically significant increase in construction 
costs.\22\ If a taxpayer believes that a particular PLA would 
significantly raise the cost of constructing a facility, a taxpayer may 
choose not to enter into a PLA. In response to concerns about hiring of 
local, minority, women, veteran, and other potentially disadvantaged 
groups, the Treasury Department and the IRS note that PLAs often 
include provisions that create or strengthen equitable paths to 
construction jobs for underserved workers, including local hire 
requirements, equitable recruitment

[[Page 53202]]

goals, and community engagement requirements. Contrary to some 
commenters' concerns, the final regulations do not require non-union 
employees to join a union or to pay union dues. The National Labor 
Relations Act permits employees to choose not to join a union in their 
workplace. 29 U.S.C. 157. Non-members may choose not to pay union dues 
and instead pay agency fees that cover only the share of dues used 
directly for representation, such as for collective bargaining or 
grievance procedures. Moreover, the final regulations do not require 
any taxpayer to sign a PLA.

---------------------------------------------------------------------------

    The Treasury Department and the IRS agree with commenters that 
qualifying project labor agreements can help ensure compliance with the 
PWA requirements. Under the final regulations, qualifying project labor 
agreements will be required to include provisions requiring the payment 
of wages at rates that are not less than the prevailing rates, include 
contract provisions complying with the Apprenticeship Requirements, and 
establish mechanisms for workers, labor organizations, and taxpayers to 
correct any underpayments. These requirements will help ensure that 
qualifying project labor agreements support compliance with the PWA 
requirements. The requirements in PLAs, including ongoing monitoring 
and administration by union officials, enforceable grievance and 
dispute resolution mechanisms, and notice of pay rates, will also help 
ensure compliance with the PWA requirements for claiming the increased 
credit amount. For example, the final regulations require that 
qualifying project labor agreements must include effective grievance 
and dispute resolution provisions that would provide workers and unions 
an independent mechanism for enforcing the PWA requirements included in 
a qualifying project labor agreement. Grievance and dispute resolution 
provisions allow workers to resolve disputes about the payment of 
prevailing wages and other violations of the qualifying project labor 
agreement before a taxpayer claims the increased credit amount, 
assisting taxpayers in complying with the final regulations.
    Regarding commenters' requests for deemed compliance or a 
rebuttable presumption of compliance, the final regulations do not 
adopt these comments. Tax jurisprudence requires taxpayers claiming a 
tax credit to demonstrate that they have met the statutory requirements 
and can substantiate their claim. The final regulations provide that 
the penalties do not apply if a taxpayer uses a qualifying project 
labor agreement and makes the required correction payments before 
filing a return claiming the credit. The Treasury Department and the 
IRS have determined that other safe harbors for PLAs or an exemption 
from a finding of intentional disregard with respect to correction 
payments would not strengthen compliance and understand this approach 
to strike the appropriate balance between recognizing PLA benefits for 
improving compliance with the PWA requirements and maintaining long-
standing tax principles.
    As the Treasury Department and the IRS noted in the preamble to the 
Proposed Regulations, pre-hire project labor agreements may be used by 
a taxpayer to incentivize stronger labor standards and worker 
protections on a construction project, and having a PLA in place may 
also help ensure compliance with PWA requirements for claiming the 
increased credit amount. Accordingly, the IRS would take into account 
on examination whether a taxpayer has a qualifying project labor 
agreement in place and would consider books and records substantiating 
that a qualifying project labor agreement is being complied with as an 
indication of compliance with the PWA requirements. For example, 
records that would support substantiating PWA compliance could include 
attestations by all counterparties that a taxpayer is in compliance 
with the terms of the qualifying project labor agreement, including the 
provisions requiring the payment of prevailing wages and the provisions 
for referring and using qualified apprentices consistent with section 
45(b)(8)(A) through (C) and guidance issued thereunder.
    Several commenters suggested additions or revisions to the proposed 
definition of a qualifying project labor agreement and requested 
clarifications. For instance, a commenter suggested clarifying that 
proposed Sec.  1.45-7(c)(6)(ii) applies to both base penalty amounts 
and any enhanced penalty due to intentional disregard. Similarly, 
commenters requested clarifying the impact of using a PLA on any 
required correction payments. Commenters also asked for the final PWA 
rules to clarify that the agreed-upon wages under a PLA are prevailing 
wages for the purposes of PWA requirements. At least one commenter 
asked whether agreed-upon wages under a PLA or a collective bargaining 
agreement could be treated as the prevailing wage for PWA purposes. 
Another commenter explained that generally, under a PLA, the taxpayer 
must pay the wage rates negotiated with the union, which are often 
higher than the prevailing wage rates set forth in DOL wage 
determinations, but under the Proposed Regulations, taxpayers must pay 
the prevailing wage rate, even if that is lower. Another commenter 
stated that asking contractors to comply with prevailing wage rates, 
which may be based on union work rates contained in collective 
bargaining agreements not publicly available, could add risk for 
contractors and reduce competition, especially from small businesses.
    Additional commenters requested permitting taxpayers to satisfy the 
Apprenticeship Requirements in the case of a PLA that includes a 
preference to use qualified apprentices, even if the PLA does not 
require compliance with all the Apprenticeship Requirements under 
section 45(b)(8). A commenter asserted that the criteria that the PLA 
must contain provisions for referring and using qualified apprentices 
consistent with section 45(b)(8)(A) through (C) and guidance issued 
thereunder was circular and did not align with PLAs generally. The 
commenter explained that the requirement that the PLA incorporate the 
IRA apprenticeship rules undercuts the PLA exception and makes it 
superfluous. An additional commenter suggested clarifying that a PLA 
for PWA purposes should allow taxpayers to use both union and non-union 
registered apprenticeship programs. A commenter also suggested revising 
the definition of a PLA to include a requirement for referring and 
using qualified journeyworkers. Similarly, a commenter asked whether a 
taxpayer may use the journeyworker-to-apprentice ratio under a PLA or a 
collective bargaining agreement for PWA purposes.
    Some commenters requested that the final regulations provide that 
PLA provisions regarding hiring union workers be optional and that 
exceptions be explicitly provided for circumstances in which union 
labor is not available. Commenters suggested that the final regulations 
should permit contractors who sign a PLA to use their own work rules 
independent of union collective bargaining agreements. One commenter 
stated that PLAs must not require payment into union benefit funds as 
long as contractors have bona fide benefits and are satisfying DBA 
standards. Similarly, a commenter recommended that the final 
regulations provide that PLAs can only require the payment of union 
dues and fringe benefits for the duration of the contract.
    A commenter requested that the final regulations adopt the 
definition for a qualifying project labor organization, largely based 
in Executive Order 14063

[[Page 53203]]

(Use of Project Labor Agreements for Federal Construction Projects), 
and permit contractors and subcontractors to compete for contracts and 
subcontracts regardless of whether they are a party to a collective 
bargaining agreement. The commenter also suggested revising the 
definition of labor organizations to require some affiliation with a 
registered apprenticeship program.
    A commenter recommended incentivizing taxpayers using a PLA to 
comply with all of the PLA's provisions, not just PWA-related 
provisions. The commenter stated that a subset of PLAs (known as 
community workforce agreements) include provisions beyond the elements 
defined in the Proposed Regulations. Additionally, a commenter 
recommended requiring service maintenance workers, like custodians, be 
included and covered under PLAs used for PWA purposes.
    Further, a commenter suggested that recordkeeping related to PLAs 
be limited to producing a valid PLA covering all laborers and mechanics 
at the site of work. The commenter also stated that it would be helpful 
to clarify the role of collective bargaining agreements and a master 
agreement, as well as the eligible status, if any, of PLAs entered and 
covering periods before the publication of the proposed rules in the 
Federal Register. The commenter also requested guidance concerning 
whether the PLA exception still applies if some, but not all, 
contractors are able to meet the PLA requirements.
    Additionally, a commenter suggested that the PWA rules align the 
criteria for PLAs with the provisions of commonly used PLA templates or 
that the final regulations adopt a new template. The commenter stated 
that the proposed rules presented six criteria for qualifying PLAs, but 
many widely used PLA templates do not meet all six criteria.
    The Treasury Department and the IRS agree with the comment to 
clarify that proposed Sec.  1.45-7(c)(6)(ii) applies to both the $5,000 
penalty and the $10,000 enhanced penalty (for the Prevailing Wage 
Requirements) and proposed Sec.  1.45-8(e)(2)(v) applies to both the 
$50 penalty and the $500 enhanced penalty (for the Apprenticeship 
Requirements) due to intentional disregard. Under the Proposed 
Regulations, the penalty payment requirement would not have applied 
with respect to a laborer or mechanic employed under a qualifying 
project labor agreement if any correction payment owed to the laborer 
or mechanic is paid on or before a return is filed claiming an 
increased credit amount. The proposed rule was intended to apply to 
both penalty amounts and requires the taxpayer to make any correction 
payment owed to any laborer or mechanic on or before the date on which 
the increased credit amount is claimed. The final regulations provide 
this clarification with respect to both the Prevailing Wage 
Requirements and the Apprenticeship Requirements.
    The proposed definition of qualifying project labor agreement 
contains six requirements, including that it must contain provisions to 
pay prevailing wages. The Treasury Department and the IRS agree with 
commenters that the definition of the term prevailing wages, for the 
purposes of a qualifying project labor agreement, requires 
clarification. The final regulations clarify the definition of 
qualifying project labor agreement to provide that it must contain 
provisions to pay wages at rates not less than the prevailing wage 
rates in accordance with subchapter IV of chapter 31 of title 40 of the 
United States Code. This clarification aligns with the statutory 
requirements regarding prevailing wage rates and maintains a clear 
standard for taxpayers and tax administration. Commenters raised that 
PLAs often require the payment of wages higher than prevailing wages 
under the DBA. A qualifying project labor agreement may require the 
payment of wages at rates that are higher than the wage rates that are 
required by section 45(b)(7)(A).
    The proposed definition of qualifying project labor agreement also 
would have provided that it must contain provisions for referring and 
using qualified apprentices consistent with section 45(b)(8)(A) through 
(C) and guidance issued thereunder. The statute defines qualified 
apprentice and provides the Apprenticeship Requirements. Accordingly, 
the final regulations do not adopt comments to modify the 
Apprenticeship Requirements for a qualifying project labor agreement.
    Regarding additions to the proposed definition of qualifying 
project labor agreement, the Treasury Department and the IRS considered 
these comments and have not adopted these comments in the final 
regulations. Specific requirements or contractual language in a PLA may 
arbitrarily exclude many PLAs from the proposed definition of a 
qualifying project labor agreement for reasons unrelated to ensuring 
compliance with the PWA requirements. A PLA is a negotiated contract 
and parties must have the appropriate flexibility to negotiate 
provisions. Nothing in the final regulations precludes parties from 
negotiating additional local hire, equity, or community engagement 
provisions in a PLA. Since each PLA is negotiated in response to unique 
project needs and labor market conditions, the Treasury Department and 
the IRS do not adopt the comment to require a PLA template.
    Specific to the nuclear industry, a few commenters proposed that 
PLA provisions in PWA rules be expanded to include collective 
bargaining agreements negotiated by nuclear operators and unions 
covering their direct employees. A commenter suggested also recognizing 
that such collective bargaining agreements establish the prevailing 
wages for their unique classification of nuclear employees that perform 
alterations or repairs. The commenter stated that there are significant 
differences in the collective bargaining and benefit practices between 
the construction and nuclear industries. A few commenters suggested 
amending the rules to permit wages paid pursuant to collective 
bargaining agreements to qualify as payment of prevailing wages under 
section 45U(d)(2). One commenter stated that at a minimum, wages paid 
pursuant to already-existing collective bargaining agreements should be 
accepted as payment of prevailing wages. Similarly, solely for purposes 
of section 45U, one commenter requested that wages and benefits paid to 
non-unionized direct employees be accepted as payment of prevailing 
wages, if the sum is equal to the collectively-bargained wages and 
benefits paid to geographically proximate direct employees of a 
qualified nuclear facility. The commenter also suggested that 
provisions regarding PLAs in the Proposed Regulations be revised to 
include taxpayers that have a collective bargaining agreement covering 
their own employees that perform alteration and repair on facilities 
eligible for the section 45U credit. The commenter also suggested that 
existing collective bargaining agreements be deemed to satisfy section 
45U(d)(2)(A). One commenter requested that wages and benefits paid 
pursuant to a collective bargaining agreement negotiated between a 
taxpayer and a union recognized as the workers' bargaining 
representative by the National Labor Relations Board, be deemed to 
comply with prevailing wage rules under section 45U.
    A commenter requested a prevailing wage safe harbor for section 45U 
to recognize the unique characteristics of nuclear power facilities. 
Another commenter requested permitting, solely for purposes of section 
45U, qualified nuclear power facilities that do not directly employ 
collectively-bargained laborers and mechanics to benchmark

[[Page 53204]]

themselves against other similar qualified nuclear power facilities 
that do directly employ collectively-bargained laborers and mechanics 
for purposes of determining whether the facility is deemed to pay 
prevailing wages to its directly employed employees. The commenter 
stated that even if not unionized, a nuclear operator's craft employees 
perform the same work under the same conditions as unionized employees 
and receive generally equivalent wages, participate in the same 
employer-sponsored benefit plans, and receive benefits equivalent to if 
not identical to unionized employees.
    The Treasury Department and the IRS recognize the nuclear power 
industry's unique circumstances and that nuclear operators cannot enter 
into qualifying project labor agreements as they would have been 
defined under the Proposed Regulations. The section 45U credit has 
Prevailing Wage Requirements for alteration or repair work of a 
qualified nuclear power facility, but not during construction. For 
taxpayers seeking the section 45U credit, a collective bargaining 
agreement provides workers conducting an alteration or repair the same 
assurances of up-front compliance that a PLA would, including union 
oversight and private enforcement. A taxpayer that has a collective 
bargaining agreement for a qualified nuclear facility that meets 
minimum requirements analogous to the minimum requirements for a 
qualifying project labor agreement should also benefit from the rule 
that penalties do not apply if any correction payment owed to a laborer 
or mechanic is paid before the increased credit amount is claimed. In 
response to the comments, the final regulations modify the definition 
of qualifying project labor agreement for section 45U. For purposes of 
section 45U, in order to be a qualifying project labor agreement, such 
agreement must, at a minimum: (i) be a collective bargaining agreement 
with a one or more labor organizations (as defined in 29 U.S.C. 152(5)) 
of which employees of the qualified nuclear power facility are members 
and such agreement establishes the terms and conditions of employment 
at the qualified nuclear power facility; (ii) contain guarantees 
against strikes, lockouts, and similar job disruptions; (iii) set forth 
effective, prompt, and mutually binding procedures for resolving labor 
disputes arising during the term of the collective bargaining 
agreement; and (iv) contain provisions to pay wages at rates not less 
than the prevailing wages in accordance with subchapter IV of chapter 
31 of title 40 of the United States Code.

VI. Applicable Scope of the PWA Requirements

    Section 45(b)(7)(A) provides that with respect to any qualified 
facility, the taxpayer must ensure that any laborers and mechanics 
employed by the taxpayer or any contractor or subcontractor in ``the 
construction of such facility'' and for the 10-year period after the 
facility is placed in service, ``the alteration or repair of such 
facility'' are paid wages at rates not less than the applicable 
prevailing wage rates. Under section 45(b)(7)(A)(ii), the prevailing 
wage rates that are required to be paid with respect to such 
construction, alteration, or repair are determined by reference to the 
prevailing rates for construction, alteration, or repair of a similar 
character in the locality in which such facility is located.
    Section 45(b)(8) sets forth the Apprenticeship Requirements that 
apply ``with respect to the construction of any qualified facility.'' 
Under the Labor Hours Requirement, section 45(b)(8)(A)(i) provides that 
taxpayers must ensure ``with respect to the construction of any 
qualified facility'' that the applicable percentage of the total labor 
hours is performed by qualified apprentices. Under the Participation 
Requirement, section 45(b)(8)(C) provides that each taxpayer, 
contractor, or subcontractor who employs four or more individuals ``to 
perform construction, alteration, or repair work with respect to the 
construction of a qualified facility'' must employ one or more 
qualified apprentices.
    The Proposed Regulations would have defined the scope of taxpayers' 
obligation to comply with the PWA requirements consistent with this 
statutory language. Under the Proposed Regulations, taxpayers would 
have been required to comply generally with respect to the construction 
of a qualified facility. The Proposed Regulations did not define the 
meaning of construction of a qualified facility for purposes of either 
the Prevailing Wage Requirements or the Apprenticeship Requirements.
    Proposed Sec.  1.45-7(d)(2)(i) would have defined ``construction, 
alteration, or repair'' to mean construction, prosecution, completion, 
or repair as defined in 29 CFR 5.2. Under 29 CFR 5.2, construction, 
prosecution, completion, or repair is defined expansively to include 
``all types of work'' done on a particular building or work at the site 
of the work, as defined in 29 CFR 5.2, by laborers and mechanics 
employed by a contractor or subcontractor. This work includes altering, 
remodeling, installing of items fabricated offsite; painting and 
decorating; manufacturing or furnishing of materials, articles, and 
supplies or equipment on the site of the work; and certain demolition 
or removal activities.
    Under the Proposed Regulations, the scope of the requirement to pay 
wages at rates not less than the prevailing rates would be clarified by 
the ``site of the work'' definition under the DBA. Under the DBA, the 
requirement to pay prevailing wages is limited by statute to work 
performed ``directly on the site of the work.'' \23\ Under the DBA, 
secondary construction sites are considered part of the site of the 
work if a significant portion of a building or work is constructed at 
the secondary site for specific use in the designated building or work 
and the site either was established specifically for the performance of 
the covered contract or project or dedicated exclusively, or nearly so, 
to the covered contract or project for a specific period of time. By 
comparison, section 45(b)(7)(A)(i) and (ii) requires the payment of 
prevailing wages generally in the construction of a qualified facility 
and the alteration or repair of such facility. As explained in the 
preamble to the Proposed Regulations, the language of section 
45(b)(7)(A) could be, but does not need to be, interpreted to support 
an expansive reading of construction such that all construction of a 
qualified facility, wherever located and however small, would be 
subject to the Prevailing Wage Requirements, resulting in a 
significantly broader scope under section 45(b)(7) than under the DBA. 
The Proposed Regulations would have taken a less expansive reading and 
applied the scope of the Prevailing Wage Requirements to the site of 
the work, consistent with the DBA rules.
---------------------------------------------------------------------------

    \23\ 40 U.S.C. 3142(c)(1).
---------------------------------------------------------------------------

    The Treasury Department and the IRS understood the DBA approach to 
the site of the work as providing useful guidance for balancing the 
requirements to pay wages at rates not less than prevailing rates with 
respect to the construction of a qualified facility and existing 
construction practices in cases in which some construction activities 
related to a facility may occur in multiple locations. This approach is 
also consistent with the principle outlined in Section I.A. of this 
Summary of Comments and Explanation of Revisions to incorporate the DBA 
requirements that are relevant for claiming the increased credit amount 
and consistent with sound tax administration. The Proposed Regulations 
would have largely adopted

[[Page 53205]]

the DBA approach (including rules relating to secondary sites) for 
purposes of defining the scope of the Prevailing Wage Requirements in 
proposed Sec.  1.45-7(d)(6). Under proposed Sec.  1.45-7(d)(6), 
taxpayers would have been subject to the requirement to ensure that 
laborers and mechanics are paid wages at rates not less than prevailing 
wage rates with respect to the construction, alteration, or repair at 
the locality in which the facility is located, which is defined to 
include any secondary sites where a significant portion of the 
construction, alteration, or repair of the facility occurs, provided 
that the secondary site either was established specifically for, or 
dedicated exclusively for a specific period of time to, the 
construction, alteration, or repair of the facility.
    Many commenters requested clarification of how the definition and 
the site of the work DBA-concept applies across the various Code 
sections for purposes of determining what work performed in the 
construction, alteration, or repair of a qualified facility is subject 
to the Prevailing Wage Requirements. Commenters also emphasized that 
the site of work definition must reflect the expanded realities of 
modern construction practices, under which a large and growing 
percentage of construction, alteration, and repair work is performed 
offsite through either prefabrication, modularization, or both. A 
commenter recommended that the site of work definition account for 
recent technological developments in which the COVID-19 pandemic 
magnified the need to build spaces that can be rapidly adjusted. A 
commenter stated that a number of legal challenges to newly added 
provisions to the regulations under the DBA are expected to be filed, 
creating ambiguity and a lack of reliability. Commenters also suggested 
providing specific examples relevant to clean energy projects.
    Commenters requested that the site of work for PWA purposes no 
longer incorporate the DOL definition, based on the DBA. Commenters 
opined that site of the work for PWA purposes should not be based on 
the scope of the DBA and should not extend to offsite or secondary 
construction sites, including manufacturing sites, access roads, 
substations, buildings, and similar property. Commenters argued that 
incorporating the DOL definition of site of the work leads to an overly 
broad application of the PWA requirements to such activities as offsite 
manufacturing facilities, dedicated production lines, or modular 
facilities that service multiple projects but that may service a single 
large project for an extended period of time--which is not uncommon in 
the clean energy industry. Commenters also sought guidance concerning 
the treatment of property such as access roads and substations that may 
not be eligible property associated with a qualified facility resulting 
in a scope of the PWA requirements reaching beyond the qualified 
facility that is eligible for the increased credit amount. One 
commenter stated that the incorporation of the site of work may subject 
some taxpayers to different enforcement schemes because the projects 
may be subject to State or local prevailing wage laws.
    Commenters also suggested that if the DBA approach is adopted in 
the final rule, that any discussion of secondary manufacturing 
facilities distinguish with examples between genuine offsite 
manufacturing activities and those that the newly expanded DBA 
definition would include. Commenters requested that the Prevailing Wage 
Requirements not apply to manufacturing facilities, dedicated 
production lines, prefabrication facilities, laydown yards, or ``mod-
yard'' locations that generally service multiple projects and 
customers. A commenter requested that the final regulations clarify 
that structures established prior to the start of construction of the 
qualified facility are not covered by the phrase ``site of the work'' 
irrespective of their adjacency or dedication to that site. The 
commenter also suggested that adjacent or virtually adjacent locations 
should not be covered by the PWA requirements if they exceed a 2-mile 
perimeter.
    In contrast, other commenters urged the Treasury Department and the 
IRS to use the DBA site of work definition for the PWA requirements, 
including secondary sites that are established specifically for the 
performance of the covered contract or project or dedicated 
exclusively, or nearly so, to the covered contract or project for a 
specific period of time. These commenters emphasized the lack of 
statutory language in the IRA limiting the application of prevailing 
wage rules based on where work in furtherance of the project is 
performed and also suggested defining site of work to cover all 
locations where construction of a covered project is performed. Another 
commenter claimed that Congress deliberately chose to draft section 
45(b)(7)(A) in broader terms than the DBA and recommended that the 
final regulations apply to all construction sites where integral 
components of the facility are constructed and dedicated support sites. 
Commenters recommended that the IRS follow DBA court decisions and 
mirror the considerations of DBA regulations.
    The Treasury Department and the IRS agree with commenters that 
additional clarity is warranted with respect to defining the scope of 
the PWA requirements. The Prevailing Wage Requirements apply with 
respect to the construction of a facility and with respect to the 
alteration or repair of a facility. The Apprenticeship Requirements 
apply with respect to construction of a facility. While the terms 
construction, alteration, and repair draw meaning from the DBA, 
Congress did not qualify the scope of such activities by the site of 
the work rule found explicitly in the DBA in defining the scope of the 
PWA requirements under the IRA. Instead, section 45(b)(7) and (8) limit 
the scope of construction, alteration, or repair to those activities 
occurring with respect to a qualified facility. The term qualified 
facility (as described in section 45 and guidance thereunder) has 
specific meaning for tax purposes.\24\
---------------------------------------------------------------------------

    \24\ See, e.g., Rev. Rul. 94-31, 1994-1 C.B. 16.
---------------------------------------------------------------------------

    The final regulations clarify that the PWA requirements apply with 
respect to a qualified facility within the meaning of section 45. The 
Treasury Department and the IRS recognize that only a portion of a 
construction project may be used to produce energy covered by the IRA 
tax credits. Under the general rule provided for in the final 
regulations, the PWA requirements apply to the portion of the activity 
that is creditable or deductible per the Code under the respective 
underlying section.\25\
---------------------------------------------------------------------------

    \25\ Accordingly, as applicable, the PWA requirements apply 
under section 30C with respect to a qualified alternative fuel 
vehicle refueling project described in section 30C(g)(1)(B) 
(consisting of one or more qualified properties within the meaning 
of section 30C(c) that are part of a single project); under section 
45L with respect to a qualifying residence described in section 
45L(a)(2)(B) (that meets the requirements of section 45L(c)(1)(A) or 
(B), as applicable); under section 45Q, with respect to a qualified 
facility and any carbon capture equipment placed in service at that 
facility within the meaning of section 45Q(d); under section 45U 
with respect to a qualified nuclear power facility within the 
meaning of section 45U(b); under section 45V with respect to a 
qualified clean hydrogen production facility within the meaning of 
section 45V(c)(3); under section 45Y with respect to a qualified 
facility within the meaning of section 45Y(b); under section 45Z, 
with respect to a qualified facility within the meaning of section 
45Z(d)(4) producing transportation fuel (as defined in section 
45Z(d)(5)) or sustainable aviation fuel (as defined in section 
45Z(a)(3)(B)); under section 48C, with respect to a qualified 
investment (as defined in section 48C(b)) in a qualifying advanced 
energy project within the meaning of section 48C(c)(1)(A); and under 
section 179D, with respect to energy efficient commercial building 
property within the meaning of section 179D(c)(1), and energy 
efficient building retrofit property pursuant to a qualified 
retrofit within the meaning of section 179(f); and in each case 
including any guidance issued thereunder the relevant Code section.

    As discussed elsewhere in this preamble, the Treasury Department 
and the IRS have incorporated DBA rules if relevant and helpful for tax 
administration. Despite the differing statutory language with respect 
to scope, the DOL approach to site of the work under the DBA 
regulations is instructive for application of the PWA requirements with 
respect to activities that may occur at locations other than the 
location of the facility. Accordingly, the final regulations continue 
to use the DBA concept of site of the work with respect to secondary 
sites to define the scope of the PWA requirements for work that occurs 
at secondary locations.
    The Treasury Department and the IRS also agree with the concerns 
raised by the commenters on how the secondary site rule could impact 
manufacturing activities that occur at offsite locations and are 
performed by unrelated parties. The final regulations clarify that 
adoption of the site of the work concept is designed to define the 
scope of the PWA requirements and prevent an application of the rules 
that would result in all work on a facility, wherever performed and 
however small, being subject to the requirements. Under the final 
regulation, unrelated third-party manufacturers who produce materials, 
supplies, equipment, and prefabricated components for multiple 
customers or the general public would not be subject to the PWA 
requirements.

VII. Prevailing Wage Requirements

A. In General
    Section 45(b)(7)(A)(i) requires that with respect to a qualified 
facility, taxpayers who are seeking an increased credit amount ensure 
that laborers and mechanics employed by the taxpayer, or any contractor 
or subcontractor in the construction of such facility are paid wages at 
rates not less than the prevailing rates determined by the DOL in 
accordance with the DBA. Section 45(b)(7)(A)(ii) further requires that 
prevailing wages are paid with respect to alteration or repair of a 
qualified facility for any portion of a taxable year that is within the 
10-year period beginning on the date the qualified facility was placed 
in service. Proposed Sec.  1.45-7(a) generally would have provided that 
a taxpayer claiming or transferring (under section 6418) the increased 
credit amount under section 45(b)(6)(B)(iii) with respect to any 
qualified facility must satisfy the requirements of section 45(b)(7) 
and proposed Sec.  1.45-7. Proposed Sec.  1.45-7(b)(1) would have 
provided that a taxpayer needs to ensure that the wages paid to 
laborers and mechanics employed by the taxpayer, contractor, or 
subcontractor in the construction, alteration, or repair of the 
facility must be not less than the prevailing rates in the geographic 
area in which such facility is located. Proposed Sec.  1.45-7(b)(6) 
would have provided that all laborers and mechanics working on a 
qualified facility must be paid in the time and manner consistent with 
the regular payroll practices of the taxpayer, contractor, or 
subcontractor.
    A few commenters requested that the final regulations require 
taxpayers, contractors, and subcontractors to adopt weekly payroll 
practices, as is required for DBA-covered contracts. The commenters 
stated that requiring weekly payroll would deter fraud and enable 
taxpayers to ensure that contractors and subcontractors comply with PWA 
requirements. Many other commenters supported the payment of prevailing 
wages consistent with the taxpayer's regular payroll practices. The 
commenters supported the flexibility of the proposed rule and stated 
that a weekly payroll requirement would not assist the IRS in 
administering the PWA requirements.
    Section 45(b)(7) requires that laborers and mechanics be paid wages 
at rates not less than the prevailing rates; there is no statutory 
requirement that laborers and mechanics must be paid on a weekly basis. 
As several commenters stated, taxpayers, contractors, and 
subcontractors should have the flexibility to pay their workers in 
accordance with their ordinary payroll schedules. For these reasons, 
these final regulations adopt the proposed rule requiring payment in 
the time and manner consistent with the regular payroll practices 
without change.
    A commenter requested that the final regulations provide an 
exception for effective compliance with the Prevailing Wage 
Requirements. The limited penalty waiver in Sec.  1.45-7(c)(6) and 
described in Section VII.D.4. of this Summary of Comments and 
Explanation of Revisions provides sufficient relief for inadvertent, 
minor errors. Another commenter suggested clarifying whether a taxpayer 
would be deemed to satisfy the Prevailing Wage Requirements for a given 
year after a facility is placed in service if neither alterations nor 
repairs were performed during that year. The final regulations clarify 
that after a facility is placed in service, taxpayers are only required 
to meet the Prevailing Wage Requirements with respect to alterations 
and repairs if alterations or repairs are actually performed during the 
relevant period.\26\ The final regulations also provide that if there 
is no alteration or repair that occurs during the relevant year, the 
taxpayer is deemed to satisfy the Prevailing Wage Requirements with 
respect to that year.
---------------------------------------------------------------------------

    \26\ This rule does not apply with respect to sections 30C, 45L, 
48C, and 179D as those Code sections do not include a continuing 
obligation for the payment of prevailing wages with respect to any 
alterations or repairs that occur after the placed in service date.
---------------------------------------------------------------------------

    Commenters asked that the final regulations clarify whether the 
applicable prevailing wage rate is based on where the project is being 
constructed or where the contractor is performing their work. Another 
commenter stated that in most cases the wages paid are based on the 
local market where the contractor or subcontractor obtains their labor. 
Section 45(b)(7)(A) provides that the prevailing wage rate is based on 
the locality of the facility that is being constructed. The Proposed 
Regulations similarly would have provided that the wage rates must be 
not less than the prevailing rates in the geographic area in which such 
facility is located. The final regulations continue to use the DBA 
concept of site of the work to address construction of a qualified 
facility that occurs at one or more secondary locations. The applicable 
prevailing wage rate that must be paid to laborers and mechanics is 
determined by the location of the work performed, which may be the 
location of the qualified facility or any secondary locations.
    The Proposed Regulations would have provided a special rule for 
qualified facilities located offshore so taxpayers would not need to 
request a supplemental wage determination for offshore facilities. 
Under the Proposed Regulations, in lieu of requesting a supplemental 
wage determination for a facility located in an offshore area within 
the outer continental shelf of the United States, a taxpayer, 
contractor, or subcontractor would be permitted to rely on the general 
wage determination for the relevant category of construction that is 
applicable in the geographic area closest to the area in which the 
qualified facility will be located. To the extent that the PWA 
requirements apply to onshore activities related to an offshore wind 
facility, one commenter suggested clarifying that the locality in which 
such onshore activities occur, and not where the offshore wind facility 
is located, would determine prevailing wage rates for those activities. 
A commenter expressed their support for permitting offshore facilities 
to use the general wage determination applicable

[[Page 53207]]

to the closest onshore area to the facility. The proposed rule is 
adopted without change. Onshore activities that are also considered 
construction of a facility within the scope of the PWA requirements 
must pay wages at rates not less than the applicable prevailing rates 
for the location of the work performed.
B. Determining the Applicable Prevailing Wage Rate
1. General Wage Determinations
    Section 45(b)(7)(A) requires that with respect to a qualified 
facility, taxpayers who are seeking an increased credit amount ensure 
that laborers and mechanics employed by the taxpayer, or any contractor 
or subcontractor, in the construction, alteration, or repair of such 
facility are paid wages at rates not less than the prevailing rates as 
most recently determined by the DOL in accordance with the DBA. As 
stated in the preamble to the Proposed Regulations, prevailing wage 
rates are those determined to be prevailing for laborers and mechanics 
for the various classifications of work performed with respect to a 
specified type of construction in a geographic area. Under the Proposed 
Regulations, prevailing wage rates would be determined by the DOL in 
accordance with the DBA if they are issued and published by the DOL as 
a general wage determination or if issued to a taxpayer as part of a 
supplemental wage determination or pursuant to a request for a wage 
rate for an additional classification.
    With respect to the proper timing of a wage determination, proposed 
Sec.  1.45-7(b)(5) would have provided that the applicable prevailing 
wage rates on a general wage determination are those in effect at the 
time construction, alteration, or repair of the facility begins, and 
generally remain valid for the duration of the work performed with 
respect to the construction, alteration, or repair of the facility by 
the taxpayer, contractor, or subcontractor. Taxpayers who perform any 
alteration or repair of a facility after the facility is placed in 
service would have been required to use the applicable wage 
determination in effect at the time the alteration or repair work 
begins.
    Commenters suggested aligning the timing of wage determinations 
with the DOL regulations under the DBA, including updates to the DBA 
regulations released in August of 2023, to minimize taxpayer confusion. 
Several commenters requested that the final regulations provide that 
prevailing wage rates be established for the entire project when 
construction contracts are executed, not when construction begins, 
consistent with the DBA. Commenters emphasized that prevailing wage 
determinations are an important factor in determining the cost of labor 
and that project costs need to be known ahead of time to accurately bid 
on contracts. Commenters asserted that waiting until construction 
begins to determine labor costs will lead to financial uncertainty and 
may discourage participation in construction projects by many 
contractors because contractors need to know what the prevailing wage 
obligations are prior to bidding for a project. The commenter stated 
that the need to apply new wage rates at the start of construction 
would be disruptive and create unnecessary financial risk for 
contractors after they have entered into a contract for construction of 
a facility.
    Commenters stated that portions of the Proposed Regulations refer 
to a contract when referencing the timing of a DBA wage determination, 
while others refer to a facility, and requested clarification. Another 
commenter stated that the approach in the Proposed Regulations 
conflicts with early guidance issued by the DOL regarding IRA 
prevailing wage compliance.\27\ A few commenters requested that the 
final regulations retain the rule that the wage determination be 
determined at the beginning of construction or revise the rule to 
provide for the determination of wage rates at the project level to 
avoid multiple wage rates for the same work. These commenters stated 
that because there is no analogous prime contract with a Federal agency 
as under the DBA, connecting the wage determination timing to the 
execution of a contract could be challenging. Commenters stated that 
determining prevailing wage rates at the project level would allow for 
greater consistency between contractors and subcontractors. Another 
commenter emphasized that each taxpayer, contractor, and subcontractor 
should be subject to the same applicable wage determination. At least 
one commenter suggested that the final regulations should permit 
taxpayers to use wage determinations at the time contracts are executed 
or when construction begins.
---------------------------------------------------------------------------

    \27\ U.S. Dept. of Labor, Davis-Bacon and Related Acts (DBRA) 
Frequently Asked Questions, Sec.  III.11, <a href="https://www.dol.gov/agencies/whd/government-contracts/construction/faq">https://www.dol.gov/agencies/whd/government-contracts/construction/faq</a>.
---------------------------------------------------------------------------

    The DBA framework is predicated on a Federal contract for the 
construction of public buildings and public works between the Federal 
Government and contractors. Under the DBA, every contract to perform 
construction, alteration, or repair to which the Federal Government is 
a party must contain a provision stating the prevailing wage rates to 
be paid to various classes of laborers and mechanics. The DBA 
regulations generally provide that the applicable wage rates for a 
contract are those in effect at the time the prime contract is awarded 
by the Federal contracting agency.\28\ By contrast, under the PWA 
requirements, there is no contracting party directly analogous to the 
Federal Government. Under the Prevailing Wage Requirements, taxpayers 
are required to ensure the payment of at least prevailing wages, but 
they may do so through the execution of multiple contracts and 
subcontracts or may perform the work with their own employees.
---------------------------------------------------------------------------

    \28\ Under 29 CFR 5.2, the term ``contract'' means any prime 
contract that is subject wholly or in part to the labor standards 
provisions of any of the laws referenced by 29 CFR 5.1 and any 
subcontract of any tier thereunder, let under the prime contract.
---------------------------------------------------------------------------

    Because of the perceived difficulty in assigning a fixed time to 
establish the applicable prevailing wage rates based on the execution 
of contracts, the proposed rules would have provided that the 
applicable prevailing rates are determined at the beginning of 
construction. However, the Treasury Department and the IRS understand 
the need for taxpayers to reduce uncertainty and determine expected 
labor costs prior to entering into contracts for the construction of a 
facility. Additionally, the Treasury Department and the IRS agree that 
the ``in accordance with'' language in section 45(b)(7) supports 
drawing from the DBA rules to determine the appropriate timing for 
establishing the applicable wage rates. Accordingly, the final 
regulations are revised to provide that the applicable prevailing rates 
are determined at the time the contract for the construction, 
alteration, or repair of the facility is executed by the taxpayer (or 
the taxpayer's designee, assignee, or agent) and a contractor. The 
prevailing wage rates at the time such contract is executed apply to 
all subcontractors of that contractor. In circumstances in which a 
taxpayer (or the taxpayer's designee, assignee, or agent) executes 
separate contracts with more than one contractor, then for each such 
contract, the applicable prevailing rates with respect to any work 
performed by the contractor (and all subcontractors of the contractor) 
are determined at the time the contract is executed by the taxpayer (or 
the taxpayer's designee, assignee, or agent) and the contractor. In the 
absence of a contract, or if a contractor or subcontractor is unable to 
determine the date of execution of the contract, the

[[Page 53208]]

final regulations provide that the applicable wage determinations are 
those in effect at the time construction starts.
    These revisions address commenters' practical business concerns 
regarding costs and financing and provide greater consistency with how 
the applicable wage rates are established under the DBA. The final 
regulations address the concern of commenters that various wage rates 
would apply, or that costs will not be able to be determined up front, 
because they apply the rate at the time the contract is executed 
between the taxpayer and a contractor to all subsequent contracts that 
flow from such contract. Thus, consistent with the DBA, the final 
regulations allow for more than one wage determination to apply with 
respect to the construction, alteration, or repair of a facility in 
cases in which a taxpayer executes separate contracts with more than 
one contractor, but nonetheless provide certainty for the taxpayer, 
contractor, and subcontractor with respect to any work performed 
pursuant to that contract.
    The final regulations also adopt a similar framework for 
alterations or repairs that occur after the facility is placed in 
service with applicable wage determinations applying when a contract is 
executed between a taxpayer and contractor for the alteration or repair 
of a facility, or absent a contract, when the repair or alteration 
starts. The final regulations also add all contracts for construction, 
alteration, or repair to the list of records that may be necessary to 
demonstrate compliance with the applicable Prevailing Wage 
Requirements.
    Under the Proposed Regulations, taxpayers generally would not have 
been required to update the applicable prevailing wage rates during 
construction of the facility in the event a new general wage 
determination was published by the DOL after construction of the 
facility begins. The preamble to the Proposed Regulations stated that a 
new wage determination would be required if the contract is changed to 
include additional, substantial construction, alteration, or repair 
work not within the scope of work of the original contract, or to 
require work to be performed for an additional time period not 
originally obligated, including in the case of an option to extend the 
term of a contract for the construction, alteration, or repair being 
exercised. Proposed Sec.  1.45-7(b)(5) mirrored the language in the 
preamble, but omitted the term substantial from the rule. The Proposed 
Regulations also would have provided that taxpayers would need to 
update the applicable wage rate(s), as necessary, with respect to any 
alteration or repair of a facility that begins after the facility has 
been placed in service. Taxpayers would do this by ensuring that wages 
are paid for such alteration or repair based on the general wage 
determination in effect when the alteration or repair begins.
    Several commenters were concerned about the requirement to update 
prevailing wage rates during the lifespan of a construction project. 
Commenters suggested clarifying how to determine when, under the 
Proposed Regulations, an additional time period not originally 
obligated has occurred that necessitates obtaining a new wage 
determination. The commenters stated that the language with respect to 
an additional time period is ambiguous and could apply to ordinary 
delays and extensions that are common in construction projects. 
Commenters requested that the terms substantial and additional be 
defined, or a de minimis value be set, to better clarify the threshold 
of new work or additional time above which taxpayers would be required 
to seek a new wage determination.
    The commenters recommended inclusion of language from the DBA 
regulations to clarify that a new wage determination is not required if 
additional time is given to complete the original commitment or if the 
additional construction, alteration, and/or repair work as part of the 
modification is merely incidental. Other commenters recommended the 
final regulations include a substantiality threshold consistent with 
DBA regulations. One commenter suggested the final regulations require 
new wage rates only if there is a cardinal change to a covered project. 
Another commenter suggested limiting the need for additional wage 
determinations to increases in the project's budget of at least 30 
percent or delays of at least 120 days to the project's expected 
completion date. One commenter suggested that the wage determination in 
effect at the beginning of a taxpayer's taxable year be used for all 
alterations and repairs occurring in the years after a facility is 
placed in service.
    The Treasury Department and the IRS agree that clarifications are 
needed and that the rules regarding when a new wage determination is 
required should be consistent with the rules under the DBA. Under the 
DBA guidance in 29 CFR 1.6, if there is additional, substantial 
construction, alteration, and/or repair work not within the scope of 
work of the original contract or order, or changes to require the 
contractor to perform work for an additional time period not originally 
obligated, including cases in which an option to extend the term of a 
contract is exercised, the contracting agency must include the most 
recent revision of any wage determination(s) at the time the contract 
is changed or the option is exercised. This does not apply if the 
contractor is simply given additional time to complete its original 
commitment or if the additional construction, alteration, and/or repair 
work in the modification is merely incidental. The DBA regulations also 
provide rules with respect to contracts for construction, alteration, 
or repair work over a period of time that is not tied to the completion 
of any specific work, such as indefinite operations and maintenance or 
repair contracts. The DBA regulations require contractors who are 
parties to these types of contracts to update the applicable wage rates 
for such contracts on an annual basis. The revised wage determination 
then applies to any alteration or repair work that begins under such a 
contract during the 12 months following the update until such 
construction work is completed, even if the completion of that work 
extends beyond the twelve-month period.
    Accordingly, the final regulations update the proposed rule to 
include the substantiality requirement discussed in the preamble to the 
Proposed Regulations, and further clarify that the requirement to 
update the wage determination does not apply if the contractor is given 
more time to complete its original commitment or if the additional work 
is merely incidental. The final regulations also update the proposed 
rule to provide that if a taxpayer enters into a contract for 
alteration or repair work over an indefinite period of time that is not 
tied to the completion of any specific work, the applicable wage rates 
must be updated on an annual basis.
2. Applicable Prevailing Wage Rate for General Wage Determinations
    The Proposed Regulations would have provided that a general wage 
determination would be one issued and published by the DOL that 
includes a list of wage and bona fide fringe benefit rates determined 
to be prevailing for laborers and mechanics for the various 
classifications of work performed with respect to a specified type of 
construction in a geographic area. As stated in the preamble to the 
Proposed Regulations, generally, the DOL conducts surveys to determine 
the prevailing rate based on wage rate data submitted by contractors, 
contractors' associations, labor organizations, public

[[Page 53209]]

officials, and other interested parties. In general, the Proposed 
Regulations would have provided that to determine the applicable 
prevailing wage rates, taxpayers would need to use the general wage 
determination(s) published by the DOL under the DBA on a DOL approved 
website. The current DOL approved website for publishing general wage 
determinations <a href="https://www.sam.gov">https://www.sam.gov</a>.
    Section 45(b)(7)(A) requires that taxpayers ensure the payment of 
prevailing wages at rates not less than the prevailing rates determined 
in accordance with the DBA. The Proposed Regulations would have largely 
incorporated the definition of wages from 29 CFR 5.2 for the Prevailing 
Wage Requirements. Under the Proposed Regulations, wages would be 
defined as the basic hourly rate of pay; any contribution irrevocably 
made by a contractor or subcontractor to a trustee or to a third person 
pursuant to a bona fide fringe benefit fund, plan, or program; and the 
rate of costs to the contractor or subcontractor that may be reasonably 
anticipated in providing bona fide fringe benefits to laborers and 
mechanics pursuant to an enforceable commitment to carry out a 
financially responsible plan or program, which was communicated in 
writing to the laborers and mechanics affected. The Proposed 
Regulations would have also incorporated by reference the rules set 
forth in 29 CFR 5.25 through 5.33 with respect to the costs for bona 
fide fringe benefits that may be credited for purposes of the payment 
of wages. The Proposed Regulations would have prescribed rules with 
respect to the payment of wages including that the payment of wages be 
made without deduction (except such payroll deductions as are required 
by the law or permitted by regulations issued by the Secretary of 
Labor) and must consist of the full amount of wages (including bona 
fide fringe benefits or cash equivalents thereof). Under the Proposed 
Regulations, whether amounts are wages for purposes of the Prevailing 
Wage Requirements would not be relevant in determining whether amounts 
are wages or compensation for other Federal tax purposes.
    One commenter suggested that prevailing wage rates established by 
the DOL fail to take into account actual compensation to workers, 
including fringe benefits, in all cases. The commenter suggested that 
to calculate prevailing wage amounts, an employer would not be able to 
take credit for the cost to set up and offer medical insurance if an 
employee opts out of medical coverage. The commenter also stated that 
taxpayers who enter into a collective bargaining agreement may be 
disadvantaged, because the agreement could set the wages and benefits 
below the prevailing wage amounts for covered employees. The commenter 
suggested establishing a safe harbor whereby a taxpayer would be deemed 
to satisfy Prevailing Wage Requirements if a substantial number--
defined as 90 percent--of their employees are paid prevailing wages.
    This comment appears to misstate the DBA requirements, and to the 
extent the comment addresses the determination of prevailing wage rates 
for purposes of the DBA, the comment is outside the scope of these 
regulations. The Proposed Regulations would have largely incorporated 
the definition of wages from 29 CFR 5.2 for the Prevailing Wage 
Requirements. Under 29 CFR 5.2 wages include any contribution 
irrevocably made by a contractor or subcontractor to a trustee or to a 
third person pursuant to a bona fide fringe benefit fund, plan, or 
program; and the rate of costs to the contractor or subcontractor that 
may be reasonably anticipated in providing bona fide fringe benefits to 
laborers and mechanics pursuant to an enforceable commitment to carry 
out a financially responsible plan or program, which was communicated 
in writing to the laborers and mechanics affected. The Proposed 
Regulations would have therefore included in the payment of prevailing 
wages, the rate of costs to an employer to provide bona fide fringe 
benefits. Additionally, the statute requires the payment of prevailing 
wages in accordance with the DBA and does not allow lower wage rates 
because there is a collective bargaining agreement or if 90 percent of 
workers have been paid the applicable wage rates. Accordingly, the 
changes suggested by the commenter are not incorporated.
    A commenter stated that the Proposed Regulations impose no 
obligation on taxpayers to confirm that fringe benefit contributions by 
contractors are made to bona fide entities. The commenter suggested 
requiring taxpayers to: (i) provide notice of an enforceable commitment 
to provide bona fide fringe benefits, and (ii) confirm that fringe 
benefit contributions made on behalf of laborers and mechanics by 
contractors and subcontractors are made to a bona fide fringe benefit 
fund, plan, or program. Another commenter request that the final 
regulations specifically allow for the payment of non-required forms of 
compensation, such as paying for a portion of health insurance, to make 
up for any wage payments that are below the prevailing wage rate.
    Consistent with the DBA, the final regulations clarify that a 
taxpayer may discharge its wage obligations for the payment of 
prevailing wages by paying the full amount in cash, by making payments 
to a bona fide fringe benefit provider or incurring costs for bona
