Alternative Fuel Commercial Vehicle Tax Credit

Businesses are eligible to receive tax credits for purchasing new alternative fuel commercial vehicles. Qualified commercial vehicles must be powered primarily by natural gas, propane, hydrogen, dimethyl ether, or electricity. Tax credit amounts vary based on gross vehicle weight rating (GVWR) and are up to 50% of the incremental cost, with maximum credit values as follows:

GVWRJanuary 1, 2016 to December 31, 2017January 1, 2018 to January 1, 2021
Up to 14,000 pounds (lbs.)$5,000$25,000
14,001 to 26,500 lbs.$10,000$50,000
Over 26,500 lbs.$20,000$100,000

This exemption also applies to qualified used vehicles modified with a U.S. Environmental Protection Agency-certified aftermarket conversion, as long as the vehicle is being sold for the first time after modification. Modified vehicles are eligible for credits equal to 30% of the commercial vehicle conversion cost, up to $25,000. The converted vehicle must be less than two years old and have an odometer reading of fewer than 30,000 miles. Beginning January 1, 2018, eligible converted vehicles must be less than ten years old and have an odometer reading of fewer than 450,000 miles.

Each entity may claim up to $250,000 or credits for 25 vehicles per year. Credits may be earned between January 1, 2016, and January 1, 2021. All credits earned must be used in that calendar year or the subsequent year. Tax credits are available on a first-in-time basis and are subject to annual limits of $2 million per weight class.
