S.C. Code Ann. § 12-6-3695 — Alternative fuel property income tax credit

(A)(1) A taxpayer who purchases or constructs, installs, and places in service in this State eligible property that is used for distribution, dispensing, or storing alternative fuel specified in this subsection, at a new or existing fuel distribution or dispensing facility, is allowed an income tax credit equal to twenty-five percent of the cost to the taxpayer of purchasing, constructing, and installing the eligible property.
(2) The entire credit may not be taken in the taxable year in which the property is placed in service, but must be taken in three equal annual installments beginning with the taxable year in which the property is placed in service. If, in one of the years in which the installment of a credit accrues, property directly and exclusively used for distributing, dispensing, or storing alternative fuel is disposed of or taken out of service and is not replaced, the credit expires and the taxpayer may not claim any remaining installment of the credit.
(3) The unused portion of an unexpired credit may be carried forward for not more than ten succeeding taxable years.
(4) The taxpayer may transfer any applicable credit associated with this section. To the extent that the taxpayer transfers the credit, the taxpayer must notify the department of the transfer in the manner the department prescribes. Notwithstanding subsection (D), as used in this item, the term "taxpayer" only applies to the State or any agency or instrumentality, authority, or political subdivision, including municipalities.
(5) A taxpayer who claims any other credit allowed pursuant to this article with respect to the costs of constructing and installing a facility may not take the credit allowed in this section with respect to the same costs.
(B) The Department of Revenue may require documentation that it considers necessary to administer the credit.
(C) To claim the credits allowed in this section, the taxpayer must place the property or facility in service before January 1, 2026.
(D) For purposes of this section:
(1) "Eligible property" includes pumps, compressors, storage tanks, and related equipment that is directly and exclusively used for distribution, dispensing, or storing alternative fuel. The equipment used to store, distribute, or dispense alternative fuel must be labeled for this purpose and clearly identified as associated with alternative fuel.
