The first US state to tax fuel was
Oregon, introduced on February 25, 1919. It was a 1¢/gal tax. In the following decade, all of the US states (48 at the time), along with the
District of Columbia, introduced a gasoline tax. By 1939, many states levied an average fuel tax of 3.8¢/gal (1¢/L). In the years since being created, state fuel taxes have undergone many revisions. While most fuel taxes were initially levied as a fixed number of cents per gallon, , nineteen states and
District of Columbia have fuel taxes with rates that vary alongside changes in the price of fuel, the inflation rate, vehicle fuel-economy, or other factors. The table below includes state and local taxes and fees. The
American Petroleum Institute uses a weighted average of local taxes by municipality population to create an average tax for the entire state. Similarly, the national average is weighted by the fuel volume sold in each state. Because many states with the highest taxes also have higher populations, more states (i.e., the less populated ones) have below-average taxes than above-average taxes. Most states exempt gasoline from general sales taxes. However, several states collect full or partial sales tax in addition to the excise tax.
Sales tax is not reflected in the rates below. ==Federal taxes==
