Who issues a Sales Tax Registration in South Carolina
In South Carolina, a sales tax registration is issued by the office below. That is the office to confirm every figure with.
- South Carolina — the state revenue or taxation department (handles state tax registration and permits)

The general US process
This sequence is the shape the process takes across the US. It is not a list of South Carolina requirements, and no step here should be read as one — the issuing office named above sets the actual requirements.
- Step 1: Work out whether you have nexus in the state — physical presence, staff, inventory, or sales above the threshold the state sets for remote sellers.
- Step 2: Register with the state revenue department. Registration is free in most states.
- Step 3: Collect the permit number the state issues, and keep it — the reseller permit is built on it.
- Step 4: Note the filing frequency the state assigns you. It is based on expected volume, not on your preference.
- Step 5: Charge the rate the state's sourcing rules point at. Many states tax at the buyer's address rather than the seller's.
- Step 6: File on schedule even in periods with no sales where the state requires a zero return.
What varies: whether the state has a sales tax at all (five do not), the economic nexus threshold, the sourcing rule, and the filing calendar.
