President Donald Trump is backing a temporary federal gas tax suspension as US drivers face sharply higher fuel prices linked to the Iran conflict.

The proposal could cut up to 18.4 cents per gallon from gasoline and 24.4 cents per gallon from diesel, but it cannot take effect without approval from Congress.

How Much Could Drivers Save?

Trump said on Monday, May 11, 2026, that he wants to remove the federal gas tax “for a period of time” and restore it once prices ease. The White House has not confirmed whether formal legislation has already been sent to lawmakers.

The relief would be limited compared with the wider rise in pump prices. US gasoline prices have climbed sharply since the Iran conflict intensified, leaving many households paying more for commuting, deliveries and daily transportation.

Congress Holds The Key

The federal gas tax helps fund highways, bridges and public transit through the Highway Trust Fund. Any suspension could give drivers short-term relief but may raise concerns over road funding.

Energy Secretary Chris Wright said the administration supports steps to lower fuel costs. Some lawmakers have also backed a temporary gas tax holiday, while critics argue the savings may not fully reach consumers.

For American families already dealing with inflation, even a small reduction at the pump could matter. But the plan’s real impact depends on Congress, fuel markets and whether gas stations pass the full tax cut to drivers.
