S.C. Code Ann. § 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.
