Gasoline carries two taxes at the pump: the federal excise of 18.40 cents per gallon (18.3 cents plus a 0.1-cent Leaking Underground Storage Tank fee), and a state tax that ranges from under 10 cents to over 70 depending on where you live. California tops the table with 73.6 cents a gallon of state levies once its extra fees stack in; Alaska sits at the bottom with 8.9. The numbers below come straight from the U.S. Energy Information Administration's official state motor-fuels table, updated monthly - not a scraped blog roundup.
Type your state and a fill-up size to see what the tax slice of your receipt looks like: twelve gallons in California sends about 11 dollars to government before a single dime reaches the oil company. Rates here are taxes only - sales taxes, cap-and-trade costs and gross-receipts levies in some states ride on top in ways the EIA table flags but does not fully price.
How to use
- Type a state name to see its state tax, the federal add-on, and the combined cents per gallon for gasoline.
- Enter a fill-up size (gallons) and the calculator shows the tax dollars on that tank - state, federal, and total.
- Compare diesel with the second column: several states tax diesel noticeably harder than gasoline, a big deal for pickup and RV owners.
Frequently asked questions
How much is the federal gas tax?
18.40 cents per gallon of gasoline - 18.3 cents of excise tax plus the 0.1-cent Leaking Underground Storage Tank (LUST) fee - and 24.40 cents for diesel, per the EIA's FAQ. The gasoline rate has been stuck at 18.3 since 1993, which is why it buys a shrinking share of highway maintenance: fixed cents per gallon lose value to both inflation and fuel efficiency, since efficient cars simply buy fewer taxed gallons.
Which state has the highest gas tax?
California, by a wide margin - 73.6 cents per gallon of state-level taxes and fees on gasoline in the EIA's July 2026 table, versus an all-state average of 32.6. Illinois (71.7), Indiana (64.5), Washington (60.2) and Pennsylvania (58.7) also sit above 50 cents. The money generally funds state transportation budgets, and several states let local add-ons ride on top, so two towns in the same state can differ slightly.
Which state has the lowest gas tax?
Alaska, at 8.9 cents a gallon of state tax - about a quarter of the national state average of 32.6. Hawaii is the next-lowest state at 18.5 cents, with several island territories in between. Alaska pairs the low rate with a permanent-fund dividend economy: the state chooses to fund services from oil revenue rather than the pump, which is a policy choice visible right in the table's extremes.
Why is my pump price different from tax math?
Because taxes are only one slice. The EIA table covers excise-style taxes; many states add sales tax on the (already taxed) price, cap-and-trade or low-carbon-fuel costs, and local option taxes that the table flags in notes but does not total. Crude oil, refining and distribution make up the rest of the price. Use this table to compare the tax component across states, not to predict the full receipt to the penny.
