How South Carolina’s threshold works

If you sell into South Carolinawithout a physical presence there, you may still be required to register for, collect, and remit sales tax once your activity crosses the state’s economic-nexus threshold. South Carolina measures this over the current or previous calendar year.

South Carolina has no transaction-count threshold: only your gross revenue into the state matters.

What counts toward the threshold

South Carolina generally counts your gross sales into the state, typically including taxable and many exempt or wholesale sales, not just your profit. Sales made through a marketplace that already collects tax for you may be counted differently; this checker measures your direct sales.

What to do if you’ve crossed it

  1. Register for a sales-tax permit with the South Carolina DOR.
  2. Start collecting South Carolina sales tax at the correct rate.
  3. File returns and remit on the state’s schedule.
  4. Consider a sales-tax professional or automation if you’re near the line in several states.

Deadlines and rates vary by state, so confirm the specifics before you act.
