Clean Fuel Vehicle Tax Credit

Taxpayers may claim a nonrefundable credit on their individual income tax, corporate franchise tax or fiduciary tax returns for the purchase or conversion of vehicles that use cleaner burning fuels. In order for a taxpayer to claim this credit they must completely fill out tax form TC-40V PDF file.

A separate form must be completed for each vehicle claimed. The credit may only be taken once per vehicle. The vehicle must be certified and claimed in the taxable year in which the item is purchased or converted. If the credit claimed exceeds the tax liability for a taxable year, the credit that exceeds the liability may be carried forward for up to five taxable years.
