Pennsylvania Gas Tax Overview

Pennsylvania’s state tax on gasoline is 58.7¢ a gallon and 74.1¢ on diesel, the rate in force since January 1, 2024. That is the 3rd-highest state gasoline tax of the 50 states and DC. Reset each January 1 from average wholesale prices; the current rates are the statutory minimum.

With the federal 18.4¢, a gallon of gasoline carries 77.1¢ of per-gallon tax, so a 15-gallon fill-up includes about $11.56 of fuel tax whatever the pump price.

The rate is due to be reset on January 1, 2027; the new figure is not published yet.
