Taxation and Finance South Carolina 4 Minutes Read ยท published February 21, 2026 Flag of South Carolina

Charleston, South Carolina businesses must follow state and local sales and use tax rules when selling goods and certain services. This guide explains who collects tax, how rates are applied, registration and remittance basics, and where retailers can find official forms and guidance. It focuses on municipal and state enforcement pathways, typical compliance steps for brick-and-mortar and online sellers, and actions to take when you receive a notice.

Check state and local pages regularly because combined rates and local options can change.

Overview

South Carolina administers the state sales and use tax; local option taxes and county or municipal levies can alter the combined rate that applies in Charleston. Retailers must register with the South Carolina Department of Revenue for a sales tax account and may need a City of Charleston business license or other local permits depending on activities and location.

Official sources for rate lookup and registration include the South Carolina Department of Revenue, the City of Charleston Finance/Business License office, and Charleston County treasury or tax collector pages.
