Alternative Fuels Tax

A state excise tax is imposed on the use of alternative fuels. Alternative fuels include liquefied petroleum gas (LPG or propane), compressed natural gas (CNG), and liquefied natural gas (LNG). The current tax rates are as follows: $0.226 per gallon of propane; $0.247 per gasoline gallon equivalent (GGE) of CNG; and $0.197 per GGE of LNG. No tax is imposed on alternative fuels used by the U.S. government or its agencies (when presented with a valid exemption certificate) or on vehicles used for urban mass transportation of passengers.
