In the U.S. Energy Information Administration’s (EIA) latest update of its data on state gasoline and diesel fuel taxes, the simple average of taxes and fees on gasoline levied by the states and the District of Columbia at the beginning of 2021 was 30 cents per gallon (¢/gal). These taxes and fees range from a low of 8.95¢/gal in Alaska to a high of 58.7¢/gal in Pennsylvania. Gasoline buyers in the United States pay these taxes in addition to the federal tax of 18.4¢/gal, which has remained unchanged since 1993.
