California gasoline excise

California's motor vehicle fuel excise, adjusted every July 1 for inflation — 63.4¢ per gallon effective July 1, 2026 (up from 61.2¢). State/district sales tax on fuel and programs like Cap-and-Trade and the Low Carbon Fuel Standard add more at the pump but aren't modeled here.

A flat excise per gal on the amount you buy.
