North Carolina Gas Tax Overview

North Carolina’s state tax on gasoline is 41.25¢ a gallon and 41.25¢ on diesel, the rate in force since January 1, 2026. That is the 9th-highest state gasoline tax of the 50 states and DC. Adjusted each January 1 by a formula weighting state population growth (75%) and energy prices (25%).

With the federal 18.4¢, a gallon of gasoline carries 59.65¢ of per-gallon tax, so a 15-gallon fill-up includes about $8.95 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.
