Alternative fuels subject to the New Mexico excise tax include propane, compressed natural gas (CNG), and liquefied natural gas (LNG). The excise tax imposed on propane is $0.12 per gallon, and the excise tax imposed on CNG and LNG is $0.133 and $0.206 per gallon, respectively. A gallon is measured as 3.785 liters of propane, 5.66 pounds (lbs.) or 126.67 standard cubic feet of CNG, and 6.06 lbs. of LNG. Alternative fuel purchased for distribution is not subject to the excise tax at the time of purchase or acquisition, but the tax is due on any alternative fuel at the time it is dispensed or delivered into the tank of a motor vehicle. Alternative fuel distributors must be licensed by the state. For tax forms and instructions, refer to the New Mexico Taxation and Revenue Department website.
