What is the difference between Minnesota's excise tax and combined tax on fuel?
Minnesota's gasoline excise tax is 29.1¢/gal — this is the pure statutory per-gallon tax set by the state legislature. The combined rate of 32.6¢/gal includes the excise plus additional state-level fees such as environmental surcharges, petroleum storage tank fees, or sales tax components. The combined rate is what drivers effectively pay per gallon.
What is the federal gas tax in 2026?
The federal gasoline excise tax is 18.4 cents per gallon and has been unchanged since October 1, 1993. The federal diesel excise tax is 24.4 cents per gallon. An additional 0.1 cent per gallon Leaking Underground Storage Tank (LUST) fee also applies to both fuels, bringing the combined federal rate to 18.5 c/gal (gasoline) and 24.5 c/gal (diesel). These taxes fund the Highway Trust Fund for interstate highway maintenance and mass transit.
What is the difference between excise rate and combined rate?
The excise rate is the pure statutory per-gallon excise tax set by the state legislature. The combined rate is the total state-level tax burden per gallon as compiled by the EIA, including the excise tax plus environmental fees, petroleum storage tank fees, inspection fees, and in some states an applicable sales tax on fuel. For most states the difference is small (under 2 c/gal), but states like California, Indiana, Illinois, Vermont, and Washington D.C. show significant gaps because they layer sales taxes or large surcharges on top of the excise.
Which state has the highest gas tax?
California has the highest combined state gas tax at 70.9 cents per gallon as of January 1, 2026, per the EIA. This includes the excise tax plus the 2.25% sales tax on gasoline. California also has the highest combined diesel tax at 87.3 c/gal. Illinois (66.4 c/gal gasoline) and Washington (59.04 c/gal) rank second and third.
