Alternative Fuel Vehicle (AFV) Tax Credit

A state income tax credit equal to 20% of the federal fuel cell, advanced lean burn, HEV, and AFV credits is available to South Carolina resident taxpayers who are eligible for and claim the federal credits. If the amount of the credit exceeds the taxpayer's liability for the applicable tax year, any unused credit may be carried forward and claimed in the five succeeding taxable years. The state tax credit is calculated without regard to the phase out period limits of Internal Revenue Code Section 30(B)(f). (Reference South Carolina Code of Laws 12-6-3377)
