FY2026 Customs Duties Year-to-Date Through May

• FY2026 Customs Duties through May 2026 reached 188,575 ($ millions) on the Monthly Treasury Statement basis.
• The prior FYTD figure for Customs Duties was 81,386 ($ millions), putting the year-over-year FYTD increase at +132%.

• Estate and Gift Taxes also rose sharply FYTD, climbing +41% to 27,951 ($ millions) from 19,855 ($ millions) the prior FYTD.
• Treasury’s Monthly Treasury Statement dataset spans 10/31/1980 through 05/31/2026 with a monthly release cadence and a next-release date of 07/13/2026, providing machine-readable CSV, JSON, and XML access to the receipts series.

Net vs Gross Tariff Revenue

• Net tariff revenue in recent years has been 80% to 85% of gross tariff and certain other excise tax revenue.
• The Joint Committee on Taxation (JCT) typically accounts for an income and payroll tax offset to excise taxes of around 25%, meaning $1 of excise tax revenue will lead to a $0.25 decline in income and payroll tax revenue per BPC.
• BPC’s data series tracks gross tariff and certain other excise tax revenue, with net tariff revenue available only on Monthly Treasury Statements after accounting for refunds.
• CRFB estimates the existing new tariffs enacted under the Trump Administration will raise about $3 trillion through FY 2035, net of offsetting effects on income and payroll taxes.
• Chaining the BPC net band midpoint and the ~25% offset onto the $195 billion gross figure, our estimate of effective new revenue lands near $121 billion, an analytical approximation rather than a Treasury-reported number.

The context: Net tariff revenue in recent years has been 80% to 85% of gross tariff and certain other excise tax revenue, with the Joint Committee on Taxation applying a roughly 25% income and payroll tax offset to excise revenue. The derived effective new revenue from FY2025 customs duties, gross times the midpoint times one minus the offset, lands close to $121 billion, materially below the $195 billion headline number.

IEEPA Tariffs and the Supreme Court Decision

• The exceptional tariff revenues collected in 2025 and early 2026 were largely authorized through the Internal Emergency Economic Powers Act (IEEPA).
• As of February 20, 2026, the Supreme Court struck down the use of IEEPA in a 6-3 decision per BPC.
• Roughly equivalent tariffs have been temporarily reinstated through Section 122 of the 1974 Trade Act following the Supreme Court ruling.
• CBP processes imported goods at 328 ports of entry and administers tariff programs authorized under Section 301 (Tariff Act of 1974), Section 232 (Trade Expansion Act of 1962), Section 122 (Trade Act of 1974), the International Emergency Economic Powers Act (IEEPA), and antidumping/countervailing duty orders.
• CBP processes drawback and refund claims for IEEPA tariffs invalidated by the February 20, 2026, Supreme Court decision via its IEEPA Duty Refunds program.
• The U.S. Trade Court ruled the majority of the new tariffs, those enacted under IEEPA, illegal per CRFB.

IEEPA Refund Exposure and FY2026 Outlook

• If upheld, roughly $90 billion of the $195 billion in tariffs collected might need to be refunded, according to data from U.S. Customs and Border Protection cited by CRFB.
• The first IEEPA refund payments began processing in early May 2026 under the CBP IEEPA Duty Refunds program.
• CRFB estimates the existing new tariffs enacted under the Trump Administration will raise about $3 trillion through FY 2035, net of offsetting effects on income and payroll taxes.
• CRFB estimates the existing new tariffs enacted under the Trump Administration will raise about $3 trillion through FY 2035, net of offsetting effects on income and payroll taxes.
• Even with refund processing underway, FY2026 Customs Duties FYTD through May 2026 remained at 188,575 ($ millions), up +132% from the prior FYTD figure of 81,386 ($ millions).
• The refund exposure of $90 billion divided by the $195 billion FY2025 customs duties total yields roughly 0.46, the upper bound on the share of FY2025 revenue at legal risk from the ruling against the IEEPA authority.

The takeaway: If upheld, roughly $90 billion of the $195 billion in tariffs collected might need to be refunded according to U.S. Customs and Border Protection data cited by CRFB. The refund exposure equals roughly half of the FY2025 customs collection and is the single largest variable on the FY2026 federal-receipts outlook.

Tariffs as a Share of Federal Revenue Historically

• Customs Duties came in at $195 Billion against Total Receipts of $5,235 Billion in FY2025.
• Tariffs’ share of total federal revenues increased sharply in early FY2026 compared to previous years.
• BPC notes that tariff revenue data comes from the U.S. Treasury Department’s Daily Treasury Statement under the Deposits category “DHS. Customs and Certain Excise Taxes”.
• FY2024 Year-to-Date federal receipts of 4,918,106 ($ millions) and outlays of 6,734,896 ($ millions) produced a FY2024 deficit of 1,816,790 ($ millions) per Table 1 of the FY2025 MTS.
• BPC’s data series uses Daily Treasury Statement deposits for tracking purposes, with net figures available after refunds.

What is the largest source of US tariff revenue?

• CBP collects all duties at the agency’s 328 ports of entry across the Section 301, Section 232, Section 122, IEEPA, and antidumping/countervailing duty orders.
• Imports from China have historically contributed the largest single-country share of US tariff revenue under the Section 301 schedules, with the IEEPA-era schedules layering additional cross-country rate increases on top.

How does fiscal-year tariff revenue differ from calendar-year figures

• The Monthly Treasury Statement covers the period 10/31/1980 through 05/31/2026 with a monthly release cadence and a next-update date of 07/13/2026.
• US Treasury figures use the federal fiscal year, October 1 through September 30. CBP-derived trackers and some Daily Treasury Statement aggregations use a calendar-year basis, so a calendar-year customs total differs from the Treasury fiscal-year total by roughly a quarter of revenue, depending on policy timing.

What happens to tariff revenue if the IEEPA refunds are processed in full

• If upheld, roughly $90 billion of the $195 billion in tariffs collected might need to be refunded, according to data from U.S. Customs and Border Protection cited by CRFB.
• The first IEEPA refund payments began processing in early May 2026 under the CBP IEEPA Duty Refunds program.
• Roughly equivalent tariffs have been temporarily reinstated through Section 122 of the 1974 Trade Act.

Conclusion

US customs duties hit roughly $195 billion in FY2025, a $118 billion or 150% increase over duties collected in 2024, per the final Monthly Treasury Statement. Through May 2026, FY2026 Customs Duties FYTD reached 188,575 ($ millions), up +132% from the prior FYTD figure of 81,386 ($ millions). CBP began processing the first IEEPA refund payments in early May 2026, following the February 20, 2026, Supreme Court decision.

The next Monthly Treasury Statement release on 07/13/2026 will show how the June 2026 reporting period closed. Researchers, fiscal-policy analysts, importers, and business journalists will find the share-of-receipts pivot, the monthly trajectory, and the refund-exposure framing the most decision-relevant cuts.
