Renewed Push for Federal Gas Tax Suspension Puts Highway Trust Fund in Jeopardy

WASHINGTON — A familiar political debate over suspending the federal gas tax has been reignited in Washington in late May and early June 2026, as the Trump administration and a group of congressional Democrats separately floated proposals for a tax holiday in response to rising fuel prices. The renewed push immediately resurrected long-standing concerns among lawmakers and industry experts about the financial stability of the nation’s primary source for infrastructure funding, the Highway Trust Fund. The proposals come as the national average for a gallon of gasoline has climbed to $4.50, according to recent reports. The federal gas tax, which has not been increased since 1993, currently stands at 18.4 cents per gallon for gasoline and 24.4 cents per gallon for diesel. Revenue from this tax is the primary funding mechanism for the Highway Trust Fund (HTF), which finances most federal spending on roads, bridges, and mass transit projects across the United States. This is not the first time lawmakers have considered such a measure. The idea of a gas tax holiday has surfaced repeatedly during periods of high fuel prices, notably during the 2008 financial crisis and again in 2022 following Russia’s invasion of Ukraine. In 2022, President Biden called for a temporary suspension, but the proposal failed to advance in Congress due to bipartisan concerns over its impact on the already-strained HTF. Those same concerns are central to the current debate. The HTF has been under financial pressure for years. Because the tax rate is not indexed to inflation, its purchasing power has significantly eroded over the past three decades. To cover shortfalls, Congress has increasingly relied on transferring money from the Treasury's general fund. According to Scott Monroe, a senior director at Fitch Ratings, the gas tax revenue alone is insufficient to meet the spending demands from states for building and maintaining their transportation networks. The rise of more fuel-efficient vehicles and the accelerating adoption of electric vehicles (EVs) further threaten the long-term viability of a consumption-based tax. A recent analysis by the think tank Resources for the Future projects that U.S. gasoline consumption could fall by as much as half by 2035, drastically reducing the tax base for the HTF. A temporary suspension would exacerbate the immediate funding crisis. According to an analysis by The Fuse, a nonprofit energy policy publication, a gas tax holiday limited to the summer months alone would result in a revenue loss of nearly $10 billion for the HTF. This would force delays on critical infrastructure projects that support the national supply chain, from the Interstate Highway System to freight rail networks and ports. To address this, the bill introduced by some congressional Democrats includes a provision to backfill the lost revenue with money from the general fund. However, critics argue this is a temporary patch that fails to address the structural funding problem and simply shifts the financial burden without creating a sustainable solution. The political appeal of a gas tax holiday is its direct, visible nature as a form of consumer relief. However, its actual effectiveness is debated. Economists have noted that there is no guarantee that the full 18.4-cent savings would be passed on to consumers, as fuel retailers and distributors could absorb a portion of the reduction. The debate comes at a critical time, as Congress is beginning to discuss the next major surface transportation bill to replace the expiring Infrastructure Investment and Jobs Act. This has forced a broader conversation about how to fund America’s infrastructure in the 21st century. Several long-term alternatives to the gas tax are being examined, though each comes with its own set of challenges. One prominent alternative is a vehicle miles traveled (VMT) tax, which would charge drivers based on how many miles they drive. While a VMT tax would capture revenue from EVs, it faces significant hurdles related to implementation costs, data privacy concerns, and potential equity issues for rural and low-income drivers who often travel longer distances. Another option, analyzed by the Tax Foundation, involves simply raising the existing gas and diesel tax rates and indexing them to inflation. While this would be the simplest to administer, it would not solve the EV revenue gap and would likely become insufficient again as EV adoption grows. For small and mid-sized businesses, the debate presents a difficult trade-off. High fuel prices directly impact operating costs for companies reliant on transportation and logistics, making a tax holiday seem attractive. However, these same businesses depend on reliable infrastructure to move goods and services efficiently. Delays caused by poorly maintained roads and bridges can lead to increased vehicle wear, higher insurance costs, and significant supply chain disruptions. In our experience, a federal gas tax holiday is a politically expedient but ultimately damaging policy for the businesses we serve. While the immediate pain of high fuel prices is real, the modest and uncertain savings from a tax suspension are far outweighed by the long-term costs of underfunding our nation's infrastructure. Reliable roads and bridges are not an expense; they are a critical asset for supply chain stability and operational efficiency. Deferring maintenance and new projects creates bottlenecks and increases costs for every business that moves goods or people. A stable, predictable funding source for infrastructure is far more valuable to long-range business planning than a temporary dip in fuel prices.

As the debate continues in Washington, all eyes will be on whether the proposals can gain traction in the Senate, where bipartisan support would be necessary for passage. The outcome will not only affect prices at the pump this summer but will also serve as a crucial indicator of the future direction of U.S. infrastructure policy and its funding mechanisms for decades to come.
