SUPPLEMENTARY INFORMATION:

Authority

    This document proposes to remove Sec.  1.6011-18 (Basis Shifting 
TOI Regulations) from 26 CFR part 1 (Income Tax Regulations). The Basis 
Shifting TOI Regulations were issued under section 6011 of the Internal 
Revenue Code (Code) pursuant to the authority granted to the Secretary 
of the Treasury or the Secretary's delegate (Secretary) under sections 
6001, 6011(a), 6111, 6112(a), 6707A(c)(1), and 7805(a) of the Code.

Background

    On June 18, 2024, the Treasury Department and the IRS published a 
notice of proposed rulemaking (REG-124593-23) in the Federal Register 
(89 FR 51476) identifying certain partnership related-party basis 
adjustment transactions and substantially similar transactions as 
transactions of interest, a type of reportable transaction (Basis 
Shifting TOI Proposed Regulations). On January 14, 2025, the Treasury 
Department and the IRS finalized the Basis Shifting TOI Proposed 
Regulations with modifications in response to comments with the 
publication of final regulations (Basis Shifting TOI Regulations) (TD 
10028) in the Federal Register (90 FR 2958).
    Since their publication, taxpayers and their material advisors have 
criticized the Basis Shifting TOI Regulations at Sec.  1.6011-18 as 
imposing complex and burdensome compliance obligations on businesses. 
The Treasury Department and the IRS considered these public comments 
and determined that the Basis Shifting TOI Regulations may be 
appropriate for removal.
    On April 17, 2025, the Treasury Department and the IRS published 
Notice 2025-23 (2025-19 IRB 1428). Notice 2025-23 announced that the 
Treasury Department and the IRS intended to publish a notice of 
proposed rulemaking proposing the removal of the Basis Shifting TOI 
Regulations from the Income tax Regulations. Notice 2025-23 further 
stated that taxpayers and their material advisors can rely on the 
notice until the Treasury Department and the IRS removed the Basis 
Shifting TOI Regulations from the Income Tax Regulations. Notice 2025-
23 additionally stated that the IRS will (i) waive penalties under 
section 6707A(a) for participants in transactions identified in the 
Basis Shifting TOI Regulations, and (ii) waive penalties under sections 
6707(a) and 6708 of the Code for material advisors to transactions 
identified in the Basis Shifting TOI Regulations.

Explanation of Provisions

    Consistent with Notice 2025-23, this notice of proposed rulemaking 
(Removal NPRM) proposes to remove the Basis Shifting TOI Regulations 
from the Income Tax Regulations.

Proposed Effective Date and Applicability Date

    The proposed removal of the Basis Shifting TOI Regulations would be 
effective on the date that the Treasury Department and the IRS publish 
final regulations (Forthcoming Final Regulations). The Treasury 
Department and the IRS intend that the Treasury decision adopting the 
Forthcoming Final Regulations will provide that participants and 
material advisors may treat the removal of the Basis Shifting TOI 
Regulations as occurring on January 14, 2025, which is the 
applicability date of the Basis Shifting TOI Regulations. Thus, 
participants and material advisors will be able to treat the Basis 
Shifting TOI Regulations as never having taken effect. See section 
7805(b)(7). Consistent with Notice 2025-23, participants and material 
advisors may continue relying on that notice until the Treasury 
Department and IRS finalize the Removal NPRM with the publication of 
the Forthcoming Final Regulations.

Special Analyses

I. Executive Order 12866, 13563, and 14192

    Executive Orders 12866 and 13563 direct agencies to assess costs 
and benefits of available regulatory alternatives and, if regulation is 
necessary, to select regulatory approaches that maximize net benefits 
(including potential economic, environmental, public health and safety 
effects, distributive impacts, and equity). Executive Order 13563 
emphasizes the importance of quantifying both costs and benefits, 
reducing costs, harmonizing rules, and promoting flexibility. This rule 
is expected to be an Executive Order 14192 deregulatory action.
    These proposed regulations have been designated by the Office of 
Management and Budget's (OMB's) Office of Information and Regulatory 
Affairs (OIRA) as subject to review under Executive Order 12866 
pursuant to the Memorandum of Agreement of July 4, 2025 (MOA) between 
the Department of the Treasury (Treasury Department) and the OMB 
regarding review of tax regulations. OIRA has determined that this 
notice of proposed rulemaking (Removal NPRM) is significant and subject 
to review under Executive Order 12866 and section 1(c) of the MOA. 
Accordingly, the Removal NPRM has been reviewed by OMB.
A. Need for Regulation
    A transaction of interest (TOI) is a type of reportable 
transaction. On January 14, 2025, the Treasury Department and the IRS 
published Sec.  1.6011-18 (Basis Shifting TOI Regulations), which 
require taxpayers and material advisors to report information 
identifying certain partnership related-party basis adjustment 
transactions. Taxpayers and their material advisors have criticized the 
Basis Shifting TOI Regulations as imposing complex and burdensome 
compliance obligations on businesses. The Treasury Department and the 
IRS received many public comments requesting that the Basis Shifting 
TOI Regulations be removed. The Treasury Department and the IRS 
considered the public comments and determined that the Basis Shifting 
TOI Regulations may be appropriate for removal.
    On April 17, 2025, the Treasury Department and the IRS published 
Notice 2025-23 (2025-19 IRB 1428), which announced that the Treasury 
Department and the IRS intended to publish a notice of proposed 
rulemaking removing the Basis Shifting TOI Regulations.
    Consistent with that intention, this notice of proposed rulemaking 
(Removal NPRM) proposes to remove the Basis Shifting TOI Regulations 
from 26 CFR part 1 (Income Tax Regulations). The proposed removal of 
the Basis Shifting TOI Regulations would be effective on the date that 
the Treasury Department and the IRS publish final regulations 
(Forthcoming Final Regulations). The Treasury Department and the IRS 
intend that the Treasury decision adopting the Forthcoming Final 
Regulations will provide that participants and material advisors may 
treat the removal of the Basis Shifting TOI Regulations as occurring on 
January 14, 2025, which is the applicability date of the Basis Shifting 
TOI Regulations. Thus, participants and material advisors will be able 
to treat the Basis Shifting TOI Regulations as never having taken 
effect. See section 7805(b)(7) of the Internal Revenue Code (Code).
B. The Statute and the Removal NPRM
    Under subchapter K of chapter 1 of the Code, a distribution by a 
partnership of the partnership's property (partnership property) or a 
transfer of an interest in a partnership (partnership interest) may 
result in an adjustment to the basis of the distributed property, 
partnership property, or both.
    A distribution of partnership property may result in an adjustment 
to the basis of the distributed property under sections 732(b) or (d) 
of the Code. In the case of a distribution of partnership property to a 
partner by a partnership with an election under section 754 of the Code 
(section 754 election), or with respect to which there is a substantial 
basis reduction as described in section 734(d) of the Code, the 
distribution may also result in an adjustment to the basis of the 
partnership's remaining property under section 734(b).
    If a partnership interest is transferred by sale or exchange or on 
the death of a partner, and the partnership either has a section 754 
election in effect or has a substantial built-in loss with respect to 
the transfer of the partnership interest as described in section 743(d) 
of the Code, the transfer may result in an adjustment to the basis of 
partnership property under section 743(b) with respect to the 
transferee partner.
    As discussed above, the Basis Shifting TOI Regulations identify 
certain partnership related-party transactions and substantially 
similar transactions that result in basis adjustments under sections 
732(b), 732(d), 734(b), and 743(b) as transactions of interest, a type 
of reportable transaction with disclosure requirements.
    The purpose of the Basis Shifting TOI Regulations is to provide 
information to the IRS that could help identify abusive basis shifting 
transactions. However, taxpayers and their material advisors have 
criticized the Basis Shifting TOI Regulations as imposing complex, 
burdensome, and retroactive disclosure obligations on many ordinary-
course and tax-compliant business activities, creating costly 
compliance obligations and uncertainty for businesses. The Treasury 
Department and the IRS agree that the compliance burden of the Basis 
Shifting TOI Regulations, as estimated below, is substantial and likely 
exceeds the benefits of the Basis Shifting TOI Regulations.
    Once the Removal NPRM is finalized, partnership related-party 
transactions and substantially similar transactions that result in 
basis adjustments would no longer be treated as transactions of 
interest. Thus, participants and material advisors to these 
transactions would no longer have the associated disclosure 
requirements.
C. Baseline
    The Treasury Department and the IRS have assessed the benefits and 
costs of these proposed regulations once finalized (as the Forthcoming 
Final Regulations) relative to a no-action baseline that reflects the 
anticipated Federal income tax-related behavior of taxpayers under the 
Basis Shifting TOI Regulations.
D. Economic Effects
1. Participants--Forms 8886
    Participants in transactions of interest must report their 
participation in the transaction on a Form 8886, Reportable Transaction 
Disclosure Statement. The Treasury Department and the IRS estimate that 
the aggregate costs of filing Forms 8886 under the Basis Shifting TOI 
Regulations each year equal the product of (1) the number of affected 
basis adjustments, (2) the average number of participants per basis 
adjustment, and (3) the average cost of filing a Form 8886 per 
participant.
a. Total Number of Basis Adjustments Affected
    Based on analysis of partnership tax return data, the Treasury 
Department and the IRS have estimated that 10,000 basis adjustments 
would be reported in the absence of the Forthcoming Final Regulations. 
Tax return data indicate as many as 12,000 basis adjustments will be 
over the numeric thresholds in the Basis Shifting TOI Regulations each 
year under sections 732(b), 732(d), 734(b), and 743(b). The Treasury 
Department and the IRS expect 10,000 of the 12,000

[[Page 11005]]

basis adjustments to generate reporting by participants. The Treasury 
Department and the IRS have determined that most participants would 
choose to report any basis adjustment over the numeric thresholds in 
the Basis Shifting TOI Regulations rather than spending additional time 
and resources on determining whether the underlying transaction 
satisfied the other requirements of the regulations. For instance, if 
there was a question as to whether the underlying transaction satisfied 
the related party rules under sections 267 and 707 of the Code, the 
Treasury Department and the IRS have determined that a participant 
would likely choose to disclose the basis adjustment rather than 
spending additional time and resources on the nuanced related party 
analysis.
b. Average Number of Participants per Basis Adjustment
    Under the Basis Shifting TOI Regulations, the type of basis 
adjustment determines the number of participants. For example, a basis 
adjustment under section 732(b) would have two participants, the 
distributee partner and the distributing partnership. In contrast, a 
basis adjustment under section 743(b) would have three participants, 
the transferor partner, the transferee partner, and the partnership. 
The Treasury Department and the IRS have therefore estimated that each 
basis adjustment would have 2.5 participants on average.
c. Average Cost of Filing a Form 8886
    The IRS's Research, Applied Analytics, and Statistics division 
(RAAS) estimates that the burden of filing Form 8886 is approximately 
10 hours, 16 minutes for recordkeeping, 4 hours, 50 minutes for 
learning about the law or the form, and 6 hours, 25 minutes for 
preparing, copying, assembling, and sending the form to the IRS, for a 
total of 21 hours and 31 minutes. In the Special Analyses of the Basis 
Shifting TOI Regulations, RAAS estimated that the appropriate wage rate 
was $102.00 (2022 dollars, equivalent to $109.33 in 2024 dollars) per 
hour. However, one commenter indicated that a better estimate is 
approximately $177.29 (2022 dollars, equivalent to $190.03 in 2024 
dollars) per hour, as many affected individuals may seek specialists 
with higher hourly fees. The Treasury Department and the IRS have 
accepted the commenter's suggested wage. Therefore, the estimated 
burden of filing Form 8886 equals $4,088.81 (2024 dollars) (that is, 
$190.03 x 21 hours and 31 minutes).
d. Summary of Yearly Economic Effects Related to Filing Form 8886
    Based on the above, the Treasury Department and the IRS estimate 
that the aggregate costs of filing Form 8886 under the Basis Shifting 
TOI Regulations are approximately $102 million per year (2024 dollars) 
(that is, the product of (i) 10,000 basis adjustments, (ii) 2.5 
participants per basis adjustment, and (iii) $4,088.81 average filing 
burden).
2. Material Advisors--Forms 8918
    Material advisors to transactions of interests identified under the 
Basis Shifting TOI Regulations must file Form 8918, Material Advisor 
Disclosure Statement. The Treasury Department and the IRS have assumed 
that the aggregate costs of filing Forms 8918 under the Basis Shifting 
TOI Regulations each year equal the product of (1) the number of 
affected basis adjustments, (2) the average number of material advisors 
per basis adjustment, and (3) the average cost of filing a Form 8918 
per advisor.
a. Total Number of Basis Adjustments Affected
    For the same reasons discussed in Section IV.A.1., the Treasury 
Department and the IRS have estimated that 10,000 basis adjustments 
would be reported under the Basis Shifting TOI Regulations.
b. Average Number of Participants per Basis Adjustment
    The Treasury Department and the IRS estimate that each transaction 
that results in a reported basis adjustment will have at least one 
professional services firm that advises on the tax implications of the 
transaction (for example, a law firm or an accounting firm) and at 
least one accounting firm that prepares the relevant tax returns. The 
Treasury Department and the IRS therefore estimate that each 
transaction that results in a reported basis adjustment will have 2.2 
material advisors on average.
c. Average Cost of Filing a Form 8918
    RAAS estimates that the burden of filing Form 8918 is approximately 
8 hours, 7 minutes for recordkeeping, 3 hours, 4 minutes for learning 
about the law or the form, and 3 hours, 20 minutes for preparing, 
copying, assembling, and sending the form to the IRS, for a total of 14 
hours and 31 minutes. If the appropriate wage rate is the same as Form 
8886 ($190.03 (2024 dollars) per hour), the burden of filing Form 8918 
is $2,758.60 (2024 dollars).
d. Summary of Yearly Economic Effects Related to Filing Form 8918
    Based on the above, the Treasury Department and the IRS estimate 
that the aggregate costs of filing Form 8918 under the Basis Shifting 
TOI Regulations equals $61 million per year (2024 dollars) (that is, 
the product of (i) 10,000 basis adjustments, (ii) 2.2 material advisors 
per basis adjustment, and (iii) $2,758.60 average filing burden).
3. Economic Effects, in Summary
    In total, the annual burden estimate related to the Basis Shifting 
TOI Regulations is $163 million (that is, $102 million per year with 
respect to Form 8886, plus $61 million per year with respect to Form 
8918). The Treasury Department and the IRS do not anticipate any other 
material economic effects of the Forthcoming Final Regulations beyond 
the filing burden reduction. Therefore, the Treasury Department and the 
IRS estimate that the aggregate economic effects of the Forthcoming 
Final Regulations would be a reduction in filing burdens by $163 
million. The Treasury Department and the IRS request comments on the 
magnitude of this estimate.

II. Paperwork Reduction Act

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520) generally 
requires that a Federal agency obtain OMB approval before collecting 
information from the public, whether such collection of information is 
mandatory, voluntary, or required to obtain or retain a benefit. An 
agency may not conduct or sponsor, and a person is not required to 
respond to, a collection of information unless the collection of 
information displays a valid control number. These proposed regulations 
(Removal NPRM), which propose removing Sec.  1.6011-18 (Basis Shifting 
TOI Regulations) from 26 CFR part 1 (Income Tax Regulations), do not 
contain a collection of information and, in fact, remove what would 
otherwise have been a collection of information requirement in the 
Basis Shifting TOI Regulations.

III. Regulatory Flexibility Act

    The Secretary of the Treasury (Secretary) hereby certifies that 
these proposed regulations (Removal NPRM) will not have a significant 
economic impact on a substantial number of small entities under the 
Regulatory Flexibility Act (RFA) (5 U.S.C. chapter 6). This 
certification is based on IRS data that allowed an estimate of the 
percentage of partnerships required to file disclosure statements under 
the proposed

[[Page 11006]]

regulations that the Department of the Treasury (Treasury Department) 
and the IRS published on June 18, 2024 (Basis Shifting TOI Proposed 
Regulations) and the final regulations published on January 14, 2025 
(Basis Shifting TOI Regulations). The data indicated that the 
percentage of partnerships that would have a disclosure obligation 
under the Basis Shifting TOI Proposed Regulations or Basis Shifting TOI 
Regulations and considered to be small business for purposes of the RFA 
would be low. Accordingly, the removal of the disclosure requirements 
under the Removal NPRM is not anticipated to have a significant 
economic impact on a substantial number of small entities.
    The RFA discussion in the Basis Shifting TOI Proposed Regulations 
referenced data provided by IRS's Research, Applied Analytics, and 
Statistics (RAAS) division, which estimated the percentage of 
partnerships with gross receipts or sales of $25 million or less that 
might have been subject to the disclosure obligations as a result of a 
basis adjustment under section 743(b) of more than $5 million during 
the taxable year. That data suggested that of all partnerships with 
related parties and a basis adjustment under section 743(b) of more 
than $5 million during the taxable year, approximately two-thirds of 
the partnerships would have gross receipts or sales of $25 million or 
less and approximately one-third would have gross receipts or sales of 
$25 million or more. The Treasury Department and the IRS determined 
that the data did not indicate that the Basis Shifting TOI Proposed 
Regulations would have a significant economic impact on a substantial 
number of small entities because not all partnerships with gross 
receipts or sales of $25 million or less are considered small 
businesses (see 13 CFR 121.201), and the data did not provide 
information on whether the partnerships with gross receipts or sales of 
$25 million or less were part of larger enterprises.
    The RFA discussion in the Basis Shifting TOI Regulations referenced 
data from the IRS that indicated that, in the case of partnerships with 
gross assets of less than $25 million that reported basis adjustments 
under section 734(b) or section 743(b) for the taxable year, the 
average basis adjustment was less than the applicable threshold amount 
of $10 million or more. Thus, the Treasury Department and the IRS 
anticipated that many partnerships with gross assets of less than $25 
million would not be subject to the disclosure requirements. Further, 
the data indicated that partnerships with gross assets of more than $25 
million that reported basis adjustments under section 734(b) or section 
743(b) for the taxable year that met the applicable threshold amount of 
$10 million or more represented less than one percent of all 
partnerships that file tax returns for the taxable year.
    Pursuant to section 7805(f), this notice of proposed rulemaking has 
been submitted to the Chief Counsel for the Office of Advocacy of the 
Small Business Administration for comment on its impact on small 
business.

IV. Unfunded Mandates Reform Act

    Section 202 of the Unfunded Mandates Reform Act of 1995 requires 
that agencies assess anticipated costs and benefits and take certain 
other actions before issuing a final rule that includes any Federal 
mandate that may result in expenditures in any one year by a State, 
local, or Tribal government, in the aggregate, or by the private 
sector, of $100 million (updated annually for inflation). These 
proposed rules do not include any Federal mandate that may result in 
expenditures by State, local, or Tribal governments, or by the private 
sector in excess of that threshold.

V. Executive Order 13132: Federalism

    Executive Order 13132 (Federalism) prohibits an agency from 
publishing any rule that has federalism implications if the rule either 
imposes substantial, direct compliance costs on State and local 
governments, and is not required by statute, or preempts State law, 
unless the agency meets the consultation and funding requirements of 
section 6 of Executive Order 13132. These proposed regulations do not 
have federalism implications and do not impose substantial direct 
compliance costs on State and local governments or preempt State law 
within the meaning of Executive Order 13132.

Comments and Requests for a Public Hearing

    Before these proposed regulations are adopted as final regulations, 
consideration will be given to comments that are submitted timely to 
the IRS as prescribed in the preamble under the ADDRESSES section. All 
comments and a plain language summary of the proposed rule will be made 
available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> or upon request. A public 
hearing will be scheduled if requested in writing by any person that 
timely submits electronic or written comments. If a public hearing is 
scheduled, notice of the date, time, and place for the public hearing 
will be published in the Federal Register.
