SB4485, titled the Gas Tax Suspension Act, would temporarily set the federal excise tax rate on gasoline and diesel fuel to zero for taxable fuel removed, entered, or sold on or after enactment and before an applicable end date. The bill also suspends the Leaking Underground Storage Tank Trust Fund financing rate during that period. In effect, it creates a federal fuel tax holiday for a limited time, with the suspension lasting 90 days by default and up to 180 days if the President determines that economic conditions justify an extension.
To offset the loss of dedicated fuel-tax revenue, the bill directs the Secretary of the Treasury to transfer amounts from the general fund to the Highway Trust Fund and the Leaking Underground Storage Tank Trust Fund equal to the foregone receipts. Those transfers are treated as if they were fuel-tax revenues for purposes of the existing trust fund allocation rules. The measure would therefore preserve the statutory funding streams for transportation and environmental cleanup accounts while temporarily eliminating the tax at the pump.
The bill would amend the Internal Revenue Code provisions governing federal motor fuel excise taxes, specifically section 4081 and the related Highway Trust Fund and Leaking Underground Storage Tank Trust Fund rules. It would temporarily reduce the federal tax burden on gasoline and diesel consumers and fuel purchasers, while shifting the fiscal cost to the Treasury’s general fund through direct transfers to the affected trust funds. The measure would affect fuel distributors, retailers, motorists, trucking and freight interests, and federal transportation financing.
No committee transcript or vote record is available, so there is no documented floor or committee debate to gauge support or opposition. Based on the bill’s structure, the measure appears designed as a consumer-relief and inflation-mitigation proposal, which typically draws support from taxpayers and fuel users. At the same time, because it replaces dedicated fuel-tax receipts with general-fund transfers, it may raise concerns among fiscal conservatives, transportation funding advocates, and budget watchdogs about revenue loss and precedent.
The main points of contention are likely to be whether suspending the gas and diesel tax would meaningfully reduce consumer costs, whether the federal government should replace dedicated trust-fund revenue with general-fund transfers, and whether a temporary tax holiday is an effective or responsible policy response to high fuel prices. Supporters would likely emphasize immediate relief for drivers, farmers, truckers, and households facing energy-cost pressure. Opponents would likely focus on the impact on federal budgeting, the Highway Trust Fund, and the possibility that fuel sellers or market conditions could absorb some of the tax reduction rather than passing it fully to consumers.
