President Donald Trump is exploring a suspension of the federal gas tax in response to soaring fuel prices, which have reached their highest levels since 2022. The proposal, which would eliminate the 18.4 cents per gallon tax on gasoline and 24.4 cents on diesel, aims to provide relief to American drivers at the pump. However, experts warn the move could exacerbate the national debt and undermine infrastructure funding.
Impacts on the Highway Trust Fund
The federal gas tax is a primary revenue source for the Highway Trust Fund (HTF), which finances critical infrastructure projects, including road repairs and bridge maintenance. Suspending the tax would deprive the HTF of billions in annual revenue, forcing the government to borrow or divert funds from other programs to compensate. Carl Davis, research director at the Institute on Taxation and Economic Policy, cautioned, 'In practice, what happens is it gets tacked on the debt.'
There's definitely an attitude in Washington that taxes can just be repeatedly cut without consequence.
Limited Relief for Consumers
While the suspension may offer temporary relief at the pump, analysts predict the reduction in prices would be marginal. Gas prices currently average $4.52 nationwide, with California experiencing the highest rates at $6.16 per gallon. The ongoing blockade of the Strait of Hormuz and stalled negotiations with Iran further complicate the outlook for fuel costs.
The proposal requires congressional approval, and Sen. Josh Hawley (R-MO) has already introduced legislation to enact the suspension. However, the HTF already operates at a deficit, projected to spend $61.4 billion in 2026 while bringing in only $44.2 billion in revenue. Critics argue that cutting the gas tax without addressing the fund's shortfall could lead to deteriorating infrastructure, including unsafe roads and bridges.
The federal gas tax has remained unchanged since 1993, failing to keep pace with inflation and rising infrastructure costs. Davis noted, 'The trust fund is repeatedly subsidized with money out of other areas of the budget.' If enacted, the suspension could leave American drivers facing both higher debt and bumpier roads.
