The "Gas Prices Relief Act of 2026" proposes a gasoline tax holiday by amending the Internal Revenue Code of 1986, setting the federal gasoline tax rate to zero and suspending the Leaking Underground Storage Tank Trust Fund financing rate until October 1, 2026. This measure aims to directly reduce the price of gasoline for consumers during this period. To prevent funding shortfalls for critical infrastructure, the bill mandates that the Secretary of the Treasury transfer equivalent amounts from the general fund to both the Highway Trust Fund and the Leaking Underground Storage Tank Trust Fund , ensuring their financial stability despite the temporary tax suspension. A central policy of Congress is that consumers must immediately receive the benefit of this tax reduction, requiring producers and dealers to lower prices accordingly. The bill includes provisions for monetary penalties against those who fail to pass on the savings and empowers the Secretary of the Treasury to enforce this consumer benefit provision.
