Gas tax — frequently asked questions
What is the federal gas tax in 2026?
The federal motor fuel excise tax is 18.4¢ per gallon on gasoline and 24.4¢ per gallon on diesel. The federal rate has been unchanged since 1993; only state and local taxes have moved. Federal revenue funds the Highway Trust Fund, which finances most interstate and bridge maintenance.
How much is gas tax by state?
State gas tax rates range from 8.95¢/gal in Alaska to over 60¢/gal in California, Pennsylvania, and Illinois. Most states layer 20–40¢/gal of state tax on top of the 18.4¢ federal rate. Some states index gas tax to inflation; others raise it via legislation as needed.
Why does gas cost more at the pump than the rate suggests?
The pump price reflects crude oil cost, refining margin, distribution and retail markup, plus combined federal + state + local taxes. In high-tax states like California, taxes alone account for ~70¢/gallon. EV-charging stations are taxed differently (often by kWh, sometimes via a separate registration surcharge).
Are gas taxes deductible?
Gas taxes are not deductible on personal federal returns. Self-employed drivers using actual vehicle expenses can include fuel costs in business deductions, but the cleaner method is the IRS standard mileage rate ($0.70/mile in 2026), which already bundles fuel, depreciation, and maintenance.
Will gas tax change in 2026?
Several states have scheduled gas-tax adjustments for 2026 (typically inflation-indexed). Federal rates remain at 18.4¢/24.4¢. Many states are also adding EV registration fees ($100–$200/year) to recoup lost gas-tax revenue as electric vehicles displace combustion engines.
