California's gasoline excise tax rose to 63.4 cents a gallon on July 1, 2026, and is adjusted each July for inflation; diesel is 48.2 cents.[5] Add the federal 18.4 cents and sales tax, and taxes alone are about $0.95 a gallon. The Cap-and-Trade and Low Carbon Fuel Standard programs add another $0.49.[4]

Why gas is so expensive in California

Higher taxes explain only part of the gap. The EIA points to California's special cleaner-burning gasoline blend, which few refineries outside the state make, and to the state's distance from other refining centers, so local refinery outages push prices up quickly.[6] The refining margin in the CEC breakdown, $1.05 a gallon, is where those supply effects show up.[4]
