How much is the 2014 federal and state tax on gasoline in the U.S.?

In 2014, the U.S. gasoline tax was 18.4 cents per gallon. State gasoline taxes varied from 12.4 cents in Alaska to 52.89 cents per gallon in California, leading to a wide variation in combined gasoline taxes across the country.

Many states in the southern and central portion of the United States featured comparatively low fuel taxes in 2014.

Many states on the West and East Coasts featured relatively high combined rates, such as the combined rate of over 68 cents per gallon in New York.
