Motor Fuel Taxes

State Gasoline Tax Reports

Summary Report: Updated January 2008 to reflect changes since July 2007
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 from the previous update and calculating a nationwide average – usually on a quarterly basis. 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.

For the first quarter of 2008, the average state gasoline tax is 28.6 cents per gallon, plus 18.4 cents per gallon federal tax making the total 47 cents per gallon.  For diesel, the average state tax is 29.2 cents per gallon plus an additional 24.4 cents per gallon federal tax making the total 53.6 cents per gallon.
