Alternative Fuel Excise Tax Credit
NOTE: This incentive was retroactively extended multiple times, most recently through December 31, 2016, by Public Law 114-113, 2015.
A tax incentive is available for alternative fuel that is sold for use or used as a fuel to operate a motor vehicle. A tax credit in the amount of $0.50 per gallon is available for the following alternative fuels: compressed natural gas (CNG), liquefied natural gas (LNG), liquefied hydrogen, liquefied petroleum gas (propane), P-Series fuel, liquid fuel derived from coal through the Fischer-Tropsch process, and compressed or liquefied gas derived from biomass. For propane, CNG, and LNG sold after December 31, 2015, the tax credit is based on the gasoline gallon equivalent (GGE) or diesel gallon equivalent (DGE). For taxation purposes, one GGE is equal to 5.75 pounds (lbs.) of propane and 5.66 lbs. of CNG. One DGE is equal to 6.06 lbs. of LNG.
For an entity to be eligible to claim the credit they must be liable for reporting and paying the federal excise tax on the sale or use of the fuel in a motor vehicle. Tax exempt entities such as state and local governments that dispense qualified fuel from an on-site fueling station for use in vehicles qualify for the incentive. Eligible entities must be registered with the Internal Revenue Service (IRS). The incentive must first be taken as a credit against the entity's alternative fuel tax liability; any excess over this fuel tax liability may be claimed as a direct payment from the IRS. The tax credit is not allowed if an incentive for the same alternative fuel is also determined under the rules for the ethanol or biodiesel tax credits. Under current law, this tax credit is applicable to fuel sold or used between January 1, 2015, and December 31, 2016. For more information about claiming the credit, see IRS Publication 510, IRS Forms 637, 720, 4136, and 8849, and IRS Notice 2015-56 (August 2015), which are available on the IRS Forms and Publications website.
