The "Gas Tax Suspension Act" proposes a temporary suspension of federal excise taxes on gasoline and diesel fuel. Specifically, it sets the tax rate under section 4081(a)(2)(A) and the Leaking Underground Storage Tank Trust Fund financing rate to zero for fuel removed, entered, or sold after the bill's enactment. This tax holiday would initially last for 90 days , with a provision allowing the President to extend it to 180 days based on economic conditions. To prevent financial shortfalls, the bill mandates that the Secretary of the Treasury transfer funds from the general fund to both the Highway Trust Fund and the Leaking Underground Storage Tank Trust Fund , compensating for the revenue lost during the suspension period.
