S.C. Code § 4-10-360
The revenues of the tax collected under this article must be remitted to the Department of Revenue and placed on deposit with the State Treasurer and credited to a fund separate and distinct from the general fund of the State. After deducting the amount of any refunds made and costs to the Department of Revenue of administering the tax, not to exceed one percent of the revenues, the State Treasurer shall distribute the revenues quarterly to the county treasurer in the county area in which the tax is imposed and the revenues must be used only for the purposes stated in the imposition ordinance. The State Treasurer may correct misallocations by adjusting subsequent distributions, but these adjustments must be made in the same fiscal year as the misallocations. However, allocations made as a result of city or county code errors must be corrected prospectively. Within thirty days of the receipt of any quarterly payment, the county treasurer or the county administrator shall certify to the Department of Revenue amounts of net proceeds applied to the costs of each project and the amount of project costs remaining to be paid and, if bonds have been issued that were approved in the referendum, a schedule of payments remaining due on the bonds that are payable from the net proceeds of the sales tax authorized in the referendum.
