Why is gas so much more expensive in certain parts of the country? One of the reasons is variance in gas taxes charged by states.

Drivers in places like Illinois and California pay more than 80 cents per gallon in gas taxes and fees, while residents of other states pay less than 30 cents per gallon, according to data from the U.S. Energy Information Administration (EIA).

The large differences in state gas taxes help explain how drivers in Southern states might pay $3 for a gallon of gas, for example, at the same time as someone in California pays closer to $5. (Aside from taxes, there are other factors that affect gas prices around the country, like proximity to refineries, weather and operating costs.)

The map below shows how gas taxes in your state stack up to averages in other locations. The numbers below include the 2023 federal gas tax of 18.3 cents per gallon.
