In some states, drivers can pay close to 90 cents per gallon in combined taxes and fees before accounting for crude oil, refining, and distribution costs.
So, here’s a breakdown of the 10 states with the highest gas taxes in 2026, from #10 to #1, including state-only taxes, total taxes with the federal gas tax, and how each state uses this revenue.
But…let’s first look at gas prices.
Why gas prices are rising right now
Gas prices are ticking up again, and for many drivers, the increase feels sudden. But the reasons behind it have less to do with local taxes and more to do with outside forces.
Right now, the national average is hovering around $3.80 per gallon, according to AAA, with some areas paying more. The biggest reason? Tension in global oil markets.
- The war conflict involving Iran has created uncertainty around the global oil supply. Oil traders tend to react to that risk, and since gasoline is refined from crude oil, those increases tend to show up at the pump.
- Limited supply can also drive up gas prices. Refineries, which convert crude oil into fuel, sometimes don’t operate at full capacity due to seasonal maintenance, unexpected shutdowns, or stricter environmental regulations.
- Additionally, transportation, storage, and retail costs can contribute to the final price consumers pay.
Taxes are still part of the equation, but they tend to change slowly.
For drivers, it means the price on the sign is often tied less to local policy and more to events unfolding overseas.
How gas taxes add to the cost per gallon
The federal government currently charges 18.4 cents per gallon of gasoline and 24.4 cents per gallon of diesel, with revenue primarily funding the Federal Highway Trust Fund for road construction and maintenance.
States add their own taxes on top of this, which can include fixed cents-per-gallon fees, percentage-based taxes, or both. In high-tax states, taxes alone can account for roughly 15% to 30% of the total price per gallon, depending on market conditions.
Some states also include additional fees, like environmental levies or inspection charges, that effectively increase the total cost per gallon. These revenues sometimes help fund transportation infrastructure, public transit, and environmental programs.
10 states with the highest gas taxes in 2026
Note: These rankings are based on state excise gas taxes. As noted for each state, total costs per gallon can be higher when additional fees and local taxes are included.
10. Rhode Island Gas Tax 2026
41.1¢ Per Gallon | Total With Federal: 59.5¢
Rhode Island consistently ranks among the highest for gas taxes despite its small size.
The gasoline tax is indexed to inflation, with adjustments every two years. Revenue funds road and bridge maintenance statewide. Drivers also pay minor environmental fees tied to fuel sales.

Drivers in more urban areas of the Commonwealth may pay slightly more than rural commuters, so total costs vary by location.

4. Pennsylvania Gas Tax 2026
58.7¢ Per Gallon | Total With Federal: 77.1¢
Pennsylvania has a long-standing, high fuel tax structure.
The state uses a wholesale price-based formula that has historically contributed to higher gas tax rates. Revenue supports highways, bridges, and public transit throughout the state.
For commuters in Philadelphia or Pittsburgh, those extra cents per gallon can significantly add to monthly fuel costs.
3. Washington Gas Tax 2026
59.0¢ Per Gallon | Total With Federal: 77.4¢
Washington’s gas tax revenue is constitutionally dedicated to transportation projects.

Drivers in the Seattle area generally benefit from well-maintained infrastructure but pay a premium at the pump.
2. Illinois Gas Tax 2026
