How fuel tax works
A fuel tax is an excise: a set number of cents on each gallon, collected whether the pump reads two dollars or five. The federal rate (18.4 cents on gasoline, 24.4 on diesel) is the same in every state and has not changed since 1993. The state rate is where the pump price diverges from one state line to the next.
