Trump Wants to Suspend the Federal Gas Tax to Lower Fuel Prices. Can He Do That?

Why It Matters

A federal gas‑tax suspension could directly reduce pump prices for consumers, but it also raises constitutional, fiscal, and partisan challenges that could shape the 2026 midterm narrative and federal budget outlook.

Key Takeaways

• Trump proposes suspending 18.4¢/gal federal gas tax
• Constitution gives tax power to Congress, not the president
• Gas tax suspension faces Democratic opposition and deficit concerns
• Georgia’s 60‑day tax holiday shows mixed state-level support
• Gas prices rose 52% since Feb., hitting $4.52 per gallon

Pulse Analysis

The federal gasoline excise tax, set at 18.4 cents per gallon, has funded the Highway Trust Fund since 1932 and accounts for roughly $2.58 of the average $63.28 cost to fill a 14‑gallon tank today. While the tax provides a stable revenue stream for road maintenance, its flat rate has become a political flashpoint as fuel prices climb sharply due to geopolitical tensions, notably the ongoing conflict in the Strait of Hormuz. Analysts note that a temporary suspension would shave a modest amount off the pump, but the broader fiscal impact could widen the $1.8 trillion deficit, prompting intense scrutiny from budget hawks.

Trump’s call to suspend the tax taps into voter frustration with high gasoline costs, especially in a midterm election year where transportation expenses are a key issue for swing voters. However, the Constitution reserves the power to levy and repeal taxes to Congress, meaning any suspension must pass both chambers. The current Gas Prices Relief Act of 2026, backed by a handful of Democratic senators, has stalled, and Republican opposition worries about deficit expansion could further impede progress. Meanwhile, Senator Josh Hawley’s separate bill signals intra‑party debate over the timing and scope of any tax holiday.

State experiments provide a glimpse of potential outcomes. Georgia’s 60‑day suspension, effective March 20, temporarily lowered the combined state and federal tax burden, but its expiration looms, leaving drivers uncertain about future costs. Other states have not followed suit, reflecting divergent fiscal philosophies. Even if a federal holiday were enacted, the modest $2.58 per‑gallon relief may be insufficient to offset the broader market forces driving prices upward, such as oil supply constraints and geopolitical risk. Policymakers thus face a trade‑off between short‑term consumer relief and long‑term fiscal responsibility, a balance that will likely influence the political calculus heading into the 2026 elections.
