The federal excise tax on gasoline is 18.4 cents per gallon and 24.4 cents per gallon on diesel. States add additional fuel taxes ranging from 8 cents (Alaska) to 77 cents (California) per gallon.

How is excise tax different from sales tax?

Excise tax is typically specific (per unit) or proportional to quantity, not price. It's assessed once at the producer/importer level. Sales tax is ad valorem (on price) and collected at retail.
