South Carolina taxes through the South Carolina Department of Revenue at a 6% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in sales. Filing runs monthly, quarterly, or annually by liability. Because South Carolina runs an annual bracket, low-volume retail and brick-and-mortar can go twelve months between returns — which is exactly how long a liability account can drift before anyone looks at it.
Employer registration runs through the South Carolina Department of Employment and Workforce, and the entity is registered with the South Carolina Secretary of State. Local option taxes vary by county, and residents over 85 qualify for a rate reduction that point-of-sale systems often miss.

South Carolina rates and sourcing
The South Carolina statewide base rate is 6%. That sits mid-table nationally, with local rates layered on top and sourced to the delivery address rather than to your own location. Sourcing is where this is won or lost, and with economic nexus set at $100,000 in sales, it becomes your problem the moment that threshold is crossed.
Filing cadence in South Carolina
South Carolina assigns filing frequency by liability — monthly, quarterly, or annually by liability. Because South Carolina includes an annual bracket, a low-volume seller here can go a full year between filings, which is exactly when a liability account drifts unnoticed. We reconcile it monthly regardless of when the return is due.
Sales tax nexus in South Carolina
Economic nexus in South Carolina is $100,000 in sales. For retail and brick-and-mortar, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the South Carolina Department of Revenue and begin collecting. We track your South Carolina sales against it and tell you before you cross, not after.
