The proposal revives a debate already seen in 2022 during the sharp rise in fuel prices after Russia’s invasion of Ukraine. Even if implemented, the measure would only reduce prices by a limited amount, since the federal tax currently adds $0.183 per gallon of gasoline and $0.243 per gallon of diesel.
Current fuel prices remain below the peaks reached in 2022 but are still significantly higher than before the conflict involving Iran began. The administration has presented the suspension of the federal gas tax as one possible response to public frustration over rising costs. At the same time, the proposal faces political, legal and economic obstacles, with questions surrounding both presidential authority and the broader impact such a measure could have on infrastructure funding and fuel markets.
The President Does Not Directly Control The Gas Tax
The federal gas tax falls under congressional authority, meaning the president cannot suspend it unilaterally. While Trump can publicly support the measure and encourage lawmakers to act, Congress ultimately controls federal taxation.
Legal experts agree that the executive branch does not have direct authority over the tax. Any attempt to bypass Congress would likely trigger legal disputes unless the Supreme Court interpreted existing law differently.
Speaking to reporters at the White House on Monday, Trump defended the idea despite its limited financial impact for drivers. “It’s a small percentage, but it’s, you know, it’s still money,” he said, according to Jalopnik.
Even with the tax removed entirely, average gasoline prices would still remain above $4 per gallon based on current national averages.
Economists Previously Questioned The Effectiveness Of The Measure
The same proposal surfaced in 2022 under President Joe Biden when fuel prices surged after Russia invaded Ukraine. At the time, economists and lawmakers from both parties expressed skepticism over the idea of suspending the federal gas tax.
Their concerns centered on supply and demand. Lower prices at the pump could increase fuel demand without increasing gasoline supply, potentially pushing prices back upward over time.
Some economists also warned that oil companies could benefit more than consumers if price reductions proved temporary. The broader concern was that suspending the tax would not address the underlying supply pressures affecting energy markets.
Opposition to the measure crossed party lines during the 2022 debate. Former House Speaker Nancy Pelosi and Senator Marsha Blackburn both opposed suspending the tax, despite major disagreements on other energy-related issues.
Billions Of Dollars For Infrastructure Are At Stake
Revenue from the federal gas tax is directed into the Highway Trust Fund, which finances road maintenance, bridge repairs and other infrastructure projects across the United States.
Suspending the tax would remove billions of dollars from that funding stream at a time when many infrastructure systems already require major investment. Critics of the proposal argued in 2022 that weakening the fund would create additional long-term problems for transportation projects nationwide.
Those concerns remain part of the debate in 2026 as lawmakers weigh whether a temporary reduction in fuel costs would justify the loss of infrastructure funding tied to the federal gas tax.
