SUPPLEMENTARY INFORMATION:
Background
Pursuant to 19 U.S.C. 1505 and Treasury Decision 85-93, published
in the Federal Register on May 29, 1985 (50 FR 21832), the interest
rate paid on applicable overpayments or underpayments of customs duties
must be in accordance with the Internal Revenue Code rate established
under 26 U.S.C. 6621 and 6622. Section 6621 provides different interest
rates applicable to overpayments: one for corporations and one for non-
corporations.
The interest rates are based on the Federal short-term rate and
determined by the Internal Revenue Service (IRS) on behalf of the
Secretary of the Treasury on a quarterly basis. The rates effective for
a quarter are determined during the first-month period of the previous
quarter.
In Revenue Ruling 2025-18, the IRS determined the rates of interest
for the calendar quarter beginning October 1, 2025, and ending on
December 31, 2025. The interest rate paid to the Treasury for
underpayments will be the Federal short-term rate (4%) plus three
percentage points (3%) for a total of seven percent (7%) for both
corporations and non-corporations. For overpayments made by non-
corporations, the rate is the Federal short-term rate (4%) plus three
percentage points (3%) for a total of seven percent (7%). For corporate
overpayments, the rate is the Federal short-term rate (4%) plus two
percentage points (2%) for a total of six percent (6%). These interest
rates used to calculate interest on overdue accounts (underpayments)
and refunds (overpayments) of customs duties remain the same as the
previous quarter. These interest rates are subject to change for the
calendar quarter beginning January 1, 2026, and ending on March 31,
2026.
For the convenience of the importing public and U.S. Customs and
Border Protection personnel, the following list of IRS interest rates
used, covering the period from July of 1974 to date, to calculate
interest on overdue accounts and refunds of customs duties, is
published in summary format.
