Trump proposes suspending US federal gas tax amid Iran war

On May 11, 2026, US President Donald Trump announced support for temporarily suspending the 18-cent-per-gallon federal gas tax to ease high fuel prices driven by the ongoing war with Iran.

Republicans in Congress introduced legislation to enact the measure, while Trump rejected Iran's latest peace proposal as unacceptable. The move aims to provide consumer relief but requires congressional approval and may have limited impact on overall prices.

  • The 18-cent federal gas tax has remained unchanged since 1993, making it one of the longest-frozen federal tax rates despite inflation.
  • Suspending the gas tax would reduce Highway Trust Fund revenue by approximately $2 billion monthly, potentially delaying infrastructure projects nationwide.

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
