What this means for your driving
Tax is a fixed number of cents on every gallon, so the less fuel you burn, the less of it you pay. A car that gets 30 mpg pays $150 a year in fuel tax over 12,000 miles in Arizona; a pickup at 19 mpg pays $236.

Arizona gas tax questions
- What is the gas tax in Arizona?
- Arizona charges 19.00¢ per gallon of gasoline in state tax: 18.00¢ of excise tax plus 1.00¢ in other per-gallon taxes and fees, according to the EIA's table updated July 2026. Add the 18.4¢ federal tax and drivers pay 37.40¢ a gallon in fuel tax.

- It is the 48th highest of 51 (the 50 states and D.C.), and 14.8¢ a gallon below the average state tax of 33.8¢.
- How much gas tax does a Arizona driver pay in a year?
- About $180 in state and federal fuel tax for a typical year of 480 gallons (roughly 12,000 miles at 25 mpg), of which $91 goes to the state. A 15-gallon fill carries $5.61 of tax.
- Is gas tax included in the price at the pump?
- Yes. Federal and state per-gallon fuel taxes are built into the price posted on the sign; they are not added at the register. That is why tax differences between neighbouring states show up directly in pump prices.
