Gas Tax Debate Reignites as Prices Stay High — Fees Account for Up to 17% of What You Pay at the Pump

If you've been wincing every time you pull up to a gas pump lately, you're not alone — and now Washington is paying attention.

Gas prices have surged dramatically since the U.S. entered a war with Iran in late February 2026. The national average hit $4.52 per gallon as of mid-May, a jump of more than 50% since the conflict began. That's the backdrop for a reignited debate in Washington over gas taxes — specifically, whether the federal government should suspend them to give drivers a break.

Here's the basic math: on average, 51 cents in taxes and fees gets added to every gallon of gas you pump. About 18 cents of that goes to the federal government, and the rest goes to your state. How much of your total price tag goes to taxes varies a lot depending on where you live — it's as low as 5% in Alaska and as high as 17% in Illinois, according to an NBC News analysis. Across all states, about 11.5% of what you pay per gallon is taxes and fees.

So what's being proposed? President Trump has said he wants to suspend the federal gas tax, calling a pause 'a great idea.' Energy Secretary Chris Wright echoed that on NBC's 'Meet the Press,' saying the administration is open to 'all ideas' to lower pump prices. Several lawmakers from both parties have introduced legislation to do exactly that — temporarily scrapping the 18.4 cents-per-gallon federal levy. Some states aren't waiting: Georgia has already suspended its state gas tax, and Indiana has announced a gas tax holiday of its own.

But here's the catch — and it's a big one. The federal gas tax cannot just disappear with a presidential signature. It would take an act of Congress. And even if Congress did act, most experts say the relief would be modest at best. If you fill up a 15-gallon tank once a week, you'd save about $2.70 per fill-up — roughly $10.80 a month. That's real money, but it won't fundamentally change how much you're spending on gas right now.

There's also a larger tradeoff most people don't know about. That 18-cent tax is the main funding source for the federal Highway Trust Fund, which pays for road construction and public transit projects across the country. The fund generates an estimated $23 billion or more per year — and it's already struggling to cover costs. A five-month suspension alone could drain $17 billion from it. Some economists warn that suspending the tax could actually push prices higher in the short run, since cheaper gas encourages more driving, which increases demand during a supply crunch.

And here's a historical footnote worth knowing: the federal gas tax hasn't been raised since 1993. In inflation-adjusted terms, that 18 cents is worth only about 8 cents today — meaning the tax's real-world value has been quietly shrinking for decades, even as road costs have climbed.

The bottom line: you're paying more at the pump because of the Iran war, not because of taxes — those have been largely flat. A gas tax holiday might trim a few dollars off your monthly fuel bill, but it comes with real strings attached for the roads and bridges you drive on every day.
