Electric Vehicle Tax Credit

June 04, 2025

Summary

H.B 2234, enacted in April 2021, created a 3¢/kWh tax on electric vehicle charging at public, for-profit charging stations. The tax will go into action on January 1, 2024. For taxable years beginning after December 31, 2023, electric vehicle owners can apply for a tax credit against these charges. The maximum amount of credit is equal to the registration fees for the electric vehicle(s) paid during the same tax year:

Vehicles under 6,000 pounds: $110 for all-electric, $82 for plug-in hybrids
Vehicles 6,000 - 10,000 pounds: $158 for all-electric, $118 for plug-in hybrids
Vehicles 10,000 - 26,000 pounds: $363 for all-electric, $272 for plug-in hybrids
Vehicles over 26,000 pounds: $2,250 for all-electric, $1,687 for plug-in hybrid

If a taxpayer's tax liability is less than the amount of credit due, the excess credit may be carried forward for up to 5 years.
