What this means for your driving

Wyoming gas tax questions
- What is the gas tax in Wyoming?
- Wyoming charges 24.00¢ per gallon of gasoline in state tax: 23.00¢ 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 42.40¢ a gallon in fuel tax.
- How does Wyoming's gas tax compare with other states?
- It is the 40th highest of 51 (the 50 states and D.C.), and 9.8¢ a gallon below the average state tax of 33.8¢.
- How much gas tax does a Wyoming driver pay in a year?
- About $204 in state and federal fuel tax for a typical year of 480 gallons (roughly 12,000 miles at 25 mpg), of which $115 goes to the state. A 15-gallon fill carries $6.36 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.
