Motor Fuel Taxes
State Gasoline Tax Reports
Here is a summary report on gasoline and diesel taxes. This report is updated quarterly. API collects motor fuel tax information for all 50 states and compiles a report and chart detailing changes and calculating a nationwide average. API's chart reflects a weighted average for each state, meaning that any taxes which can vary across a state's jurisdiction are averaged according to the population of the local areas subject to each particular tax rate. Where appropriate, the weighted average also takes into consideration the typical percentages of premium, midgrade, and regular fuel purchased in each state. In states where taxes vary depending upon the price of the motor fuel (for example, where the tax rate is set as a percentage of the sales price rather than a cents per gallon method), the state average listed on the chart is a snapshot based upon the price of fuel (as reported by AAA) on the date the chart is updated. Be sure to also look at the "Notes" attachment for a detailed explanation of the various taxes included in our chart.
