**Federal gas tax suspension remains unlikely without congressional action amid elevated pump prices driven by the Iran conflict and related supply disruptions.** Multiple bipartisan bills have circulated in 2026 to pause the 18.4-cent gasoline and 24.4-cent diesel excise taxes, with support from President Trump and some lawmakers seeking relief ahead of November midterms. However, House efforts in mid-September stalled over lack of consensus on duration and revenue offsets for the Highway Trust Fund, leaving proposals in committee without a floor vote. The president lacks unilateral authority to suspend the tax, as it is set by statute. Numerous states have enacted their own temporary holidays or reductions, but no federal suspension has occurred historically despite repeated proposals. Key upcoming factors include midterm outcomes and any renewed legislative pushes before year-end.
