Did rising tariff revenue keep the federal deficit from growing?
Core argument: The Congressional Budget Office estimates the federal deficit was $1.8 trillion in fiscal year 2025, $8 billion less than in fiscal year 2024, with revenues up an estimated $308 billion (6%) and outlays up an estimated $301 billion (4%).
The federal budget deficit was $1.8 trillion in fiscal year 2025, the CBO estimates, $8 billion less than the shortfall recorded during fiscal year 2024. Revenues increased by an estimated $308 billion (or 6%); increases in collections of individual income taxes and customs duties were partially offset by a decline in corporate tax receipts. Receipts from customs duties (including tariffs) increased by $118 billion (or 153 percent) relative to fiscal year 2024. Outlays rose by an estimated $301 billion (or 4%). Outlays were higher in several areas, including the largest benefit programs and net interest on the public debt (which, for the first time, surpassed $1 trillion). Decreases in outlays recorded for federal student loan programs, deposit insurance, and by the Small Business Administration partly offset those increases. The change in the deficit was influenced by the timing of outlays in fiscal year 2024, which were reduced because payments that were due on October 1, 2023, a Sunday, were shifted into fiscal year 2023 (they were made in September 2023). If not for those shifts, the 2025 deficit would have been $80 billion (or 4%h) less than the shortfall in 2024.
