Alternative Fuel Excise Tax
Distributors who sell or use motor fuel, including special fuels, are subject to an excise tax of $0.26 per gallon. Motor fuels that are not commonly sold or measured by the gallon and are used in motor vehicles on public highways are taxed according to their gasoline gallon equivalent (GGE). A GGE of compressed natural gas (CNG) must be at least 110,000 British thermal units and a GGE of liquefied natural gas (LNG) must be at least 6.06 pounds. CNG is defined as a mixture of hydrocarbon gases and vapors, consisting principally of methane in gaseous form that has been compressed for use as a motor fuel. LNG is defined as methane or natural gas in the form of a cryogenic or refrigerated liquid for use as a motor fuel. Propane and special fuels sold in bulk to a licensed consumer distributor are exempt from this tax. The Georgia Department of Revenue may assess, levy, and collect tax for any other motor fuels used on public highways using a GGE rate.
