Qualified taxpayers are eligible for a tax credit for the purchase of a qualified heavy-duty AFV. Qualifying fuels include natural gas, electricity, and hydrogen. Each qualified heavy-duty AFV is eligible for the following tax credit amounts:

Year Credit Amount
2019 $18,000
2020 $15,000

At least 50% of the qualified vehicle's miles must be driven in the state. A single taxpayer may claim credits for up to 10 AFVs or $500,000 annually. If more than 30% of the total available tax credits in a single year have not been claimed by May 1, a taxpayer may apply for credits for an additional eight AFVs. Up to 25% of the tax credits are reserved for taxpayers with small fleets of less than 40 vehicles. This credit expires December 31, 2020. Additional conditions and restrictions may apply. For more information, see the Alternative Fuel Heavy Duty Vehicle Tax Credit Program website.
