Alternative Fuel Tax

The excise tax imposed on compressed natural gas (CNG), liquefied natural gas (LNG), and propane used to operate a vehicle can be paid through an annual flat rate sticker tax based on the following vehicle weights:

Alternatively, owners and operators may pay an excise tax on CNG of $0.0887 per gasoline gallon equivalent (GGE) measured at standard pressure and temperature, $0.1017 for each diesel gallon equivalent (DGE) of LNG, and $0.06 per gallon of propane. One GGE is equal to 126.67 cubic feet or 5.66 lbs. of CNG and one DGE is equal to 6.06 lbs. of LNG. The excise tax on ethanol and methanol fuel blends containing up to 15% gasoline or diesel fuel is one-half the tax on gasoline and diesel prescribed by California Revenue and Taxation Code section 8651.
