S.C. Code Ann. § 4-10-460
The tax authorized in this article may be renewed and imposed within a county in the same manner as proceedings for the initial imposition of the tax. A referendum on the question of reimposition of a tax must not be held more than two years before the date upon the tax then in effect is scheduled to terminate, but any reimposition is effective immediately upon the termination of the tax previously imposed.
