S.C. Code Ann. § 12-60-500: Tax refund; preference to other claims against state treasury.

If it is determined that a refund is due of a tax paid to, or collected by the State, the department shall issue its order to the State Treasurer to refund the taxes. Refunds must be paid in preference to other claims against the state treasury. If the State Treasurer does not have in his custody or possession enough funds to pay a refund of taxes, he shall request that the General Assembly appropriate the refund.
