2017 Gas Tax Increase

The base 18 cents per gallon state excise tax on gasoline rose 12 cents on Nov. 1, 2017 to 30 cents per gallon. This marks the first increase in the state's base gas tax since 1994. The 18.4 cents per gallon federal excise tax on gasoline has not been raised since 1993.

The increase in the state gas tax was authorized through state Senate Bill 1 (Beall, 2017), which was approved by the state Legislature and signed into law by Gov. Brown in April 2017. The 12-cents-per-gallon increase restores the purchasing power of the state gas tax to mid-1990s levels. Learn more about Senate Bill 1.
