State taxes and fees on motor gasoline as of 1 January 2026, ranged from a high of US¢70.9/gal. in California to a low of US¢9.0/gal. in Alaska. State gasoline taxes averaged US¢33.5/gal. across states, a slight increase from their average in 2025.
The EIA compiles this information twice a year by collecting tax and fee information as of 1 January and 1 July, as those dates align with the timing of many states’ changes in taxes. Twenty-six states have changed their gasoline taxes between the first day of 2025 and the first day of 2026, with 19 states raising taxes and 7 states lowering taxes. Two notable changes included Michigan’s tax increase of US¢20.8/gal. and Washington state’s increase of US¢6.2/gal. All other states’ gasoline tax changes were within US¢5/gal. of their 1 January 2025 value.
The EIA also publishes state-level diesel taxes and fees, which ranged from a high of US¢87.3/gal. in California to a low of US¢9/gal. in Alaska and averaged US¢35.9/gal. across all states. These state taxes do not include the federal gasoline tax of US¢18.4/gal. and federal diesel tax of US¢24.4/gal., which have remained unchanged since October 1993.
Consumers in California often pay among the highest prices for gasoline in the US. In addition to excise taxes and other fees, California requires a special blend of gasoline that requires more processing steps and more expensive blending components but is intended to alleviate air quality issues associated with gasoline consumption.
