Plug-In Hybrid Electric Vehicle (PHEV) Tax Credit
For taxable years before 2017, an income tax credit is available for the in-state purchase or lease of a new PHEV. For the purpose of this incentive, a PHEV is a vehicle equipped with an internal combustion and an electric engine with an all-electric range of at least nine miles, uses an external source of energy to charge the battery, and has at least four kilowatt hours (kWh) of battery capacity. The credit is equal to $667, plus $111 if the vehicle has at least five kWh of battery capacity, plus an additional $111 for each additional kWh, with a maximum allowed credit of $2,000. Low- or medium-speed vehicles do not qualify for this credit. Total claims for all taxpayers in one year may not exceed $200,000 and are available on a first-come, first-served basis.
