(d) To the extent loans are forgiven and excluded from gross income for federal income tax purposes under the paycheck protection program in Section 1102 of the Coronavirus Aid, Relief, and Economic Security Act (Public Law 116-136), or from any extension of the paycheck protection program, those loans are excluded for South Carolina income tax purposes. Further, to the extent the federal government allows the deduction of expenses associated with the forgiven paycheck protection program loans, these expenses will be allowed as a deduction for South Carolina income tax purposes.

(c) For a taxpayer utilizing the provisions of Internal Revenue Code Section 1341 (Computation of Tax where Taxpayer Restores Substantial Amount Held under Claim of Right) for South Carolina tax purposes the phrase "taxes imposed by this chapter" means taxes imposed by Chapter 6 of this title.
(d) The terms defined in Internal Revenue Code Sections 7701, 7702, and 7703 have the same meaning for South Carolina income tax purposes, unless a different meaning is clearly required.
