What is Minnesota's gas tax rate?

Minnesota's gasoline excise tax is roughly 28.5 cents per gallon plus a small inspection and cleanup surcharge, putting the effective state rate near 31.8 cents per gallon. Diesel is taxed at the same base excise. Minnesota indexes the rate to inflation starting in 2024, so it rises gradually.

Does Minnesota charge sales tax on gasoline?

No. Minnesota does not apply its general sales tax to motor fuel. Instead it charges a per-gallon excise tax plus a small petroleum tank cleanup fee, all of which are built into the pump price you see.

How much federal gas tax do I pay?

The federal gasoline excise tax is 18.4 cents per gallon and the federal diesel excise is 24.4 cents per gallon. These rates have been unchanged since 1993 and are added on top of Minnesota's state excise at the pump.

Is gas tax included in the pump price?

Yes. Both the Minnesota state excise and the federal excise are baked into the per-gallon price you see at the pump, so you never pay them separately. This calculator breaks out how much of your annual spending is tax.

How is tax per mile calculated?

Tax per mile is the combined per-gallon excise divided by your fuel economy in miles per gallon. A more efficient vehicle spreads the same per-gallon tax over more miles, so it pays less fuel tax for each mile driven.

Every gallon you pump in Minnesota includes a state excise tax and a federal excise tax built into the price. This calculator shows how much fuel tax you pay over a year and breaks it down to the cost per mile driven.

How it works

You can estimate your gallons two ways, then the tool applies both excise rates:

gallons = annual miles ÷ mpg   (or)   tank size × fill-ups per year
state tax = gallons × Minnesota excise
federal tax = gallons × federal excise
tax per mile = (Minnesota excise + federal excise) ÷ mpg

Minnesota’s effective state excise is about 31.8 cents per gallon (a 28.5-cent base plus a small petroleum tank cleanup surcharge) and applies to both gasoline and diesel. Federal excise adds 18.4 cents for gasoline and 24.4 cents for diesel.

Example

Driving 12,000 miles a year at 25 mpg burns about 480 gallons. At 31.8 cents Minnesota excise that is roughly $153 in state tax, plus about $88 federal at 18.4 cents, for about $241 of fuel tax a year, or roughly 2 cents per mile.

Notes

These excise rates are included in the pump price, not added separately. Starting in 2024 Minnesota indexes its fuel tax to highway construction cost inflation, so the rate rises gradually each year — confirm the current figure at revenue.state.mn.us. The tool covers excise only; Minnesota does not apply general sales tax to motor fuel.
