Gas tax by state: the 7.1 times gap at the pump

Gasoline tax is the most visible tax most people never see itemized. It is built into the pump price, charged per gallon rather than per dollar, and set independently by each state. The spread is wide: 8.95c a gallon in Alaska against 63.40c in California. Here is every state, plus what the gap is worth on a tank of fuel.

What the full table shows

  1. The gap is worth about $8.17 a tank. Filling 15 gallons in California carries roughly $8.17 more state tax than the same fill in Alaska. Over 500 gallons a year that is about $272.25. Both volumes are illustrative, so scale them to your own driving.
  2. The federal rate is the same everywhere and has not moved since 1993. 18.4 cents a gallon applies on top of every figure below. Because it is fixed in cents rather than indexed, inflation has quietly cut its real value for three decades, which is why states have raised their own rates to fill the gap.
  3. A per-gallon tax shrinks as cars improve. Excise is charged on volume, not value, so revenue falls as vehicles get more efficient and does not rise when prices do. That structural problem, not appetite for taxation, is behind most recent rate changes and the electric-vehicle fees several states have added.
  4. Tax explains part of the pump-price gap, not all of it. Crude cost, refining, blend rules, distribution and local competition move the retail price too, and some states add general sales tax or local option taxes on top of the excise shown here.

Method, and what these figures exclude

  • State excise only. Figures are the state gasoline excise rate for 2026. The federal 18.4 cents a gallon is excluded from the bars and applies everywhere.
  • Other fuel charges are excluded. Some states levy general sales tax on fuel, environmental or inspection fees, or allow local option taxes. Those can add several cents and are not in the excise figure.
  • Gasoline, not diesel. Diesel is usually taxed at a different rate.
  • Rates move. Several states index their rate to inflation or to fuel prices, so a figure verified on 2026-07-16 can change at the next statutory adjustment.
  • The tank and annual volumes are assumptions. 15 gallons and 500 gallons a year are illustrative figures chosen to make the gap concrete, not sourced national averages.

Sources and reuse

  • Each state's rate is taken from that state's own revenue or transport authority; the authority for every row is listed in the table above. Verified 2026-07-16.
  • Federal excise rate: IRS Publication 510, Excise Taxes.
  • Per-state calculators and detail: our US calculators.

Frequently asked questions

Which state has the highest gas tax?

California at 63.40c a gallon, followed by Pennsylvania at 57.60c. The lowest is Alaska at 8.95c, which is about 7.1 times less. The median state charges 30.00c.

How much does the gas tax gap actually cost me?

On a 15 gallon fill-up, the difference between the highest and lowest state is about $8.17. For a driver buying 500 gallons a year, roughly $272.25 a year. Those two volumes are illustrative assumptions, not sourced averages: multiply the cent difference by your own gallons to get your figure.

Is the federal gas tax included in these figures?

No. These are state excise rates only. The federal gasoline excise tax of 18.4 cents a gallon applies on top in every state and has not changed since 1993. Add it to any state figure here for the combined excise burden, before any sales tax or local levy.

Why is the pump price not simply the tax difference?

Pump price reflects crude oil cost, refining, distribution, retail margin, blend requirements and local competition as well as tax. State tax explains part of the gap between states, not all of it. Some states also apply general sales tax or local option taxes on fuel, which are not in the excise figures here.

Where does gas tax money go?

In most states the gasoline excise is dedicated to roads, bridges and transport infrastructure, often by constitutional or statutory earmark. Because it is charged per gallon rather than per dollar, revenue does not automatically rise with fuel prices, and it falls as vehicles become more efficient. That is why several states index the rate or have replaced part of it with other charges.
