The Tariff Trust Fund (TRUST Act) would create a new Tariff Trust Fund in the U.S. Treasury and set a conditional rule for depositing tariff revenue into that fund. If the federal government runs budget deficits in two consecutive fiscal years starting in 2026, any tariff receipts in the following year that exceed the 2025 tariff receipts would be deposited into the Tariff Trust Fund. Those deposited amounts would then be transferred to the general fund and used exclusively for deficit reduction. The act takes effect upon enactment and would apply to tariff collections beginning October 1, 2025. In short, the bill creates a temporary mechanism to earmark excess tariff revenue during certain deficit conditions, with the funds ultimately directed toward reducing the deficit.
