How Workers' Comp rates are set in South Carolina
South Carolina runs a private Workers' Comp market. Rate filings are reviewed by the South Carolina Department of Insurance. We track 1 distinct classification(s) for South Carolina across 1 active filing(s). Workers' Comp loss costs are filed by NCCI in most states or by an independent state rating bureau; your actual premium is that filed loss cost multiplied by your carrier's loss-cost multiplier (LCM), your experience modifier, and your payroll divided by $100 — so two South Carolina businesses in the same classification can pay very different rates. Comparing quotes from multiple carriers is the only way to see how those multipliers differ for your specific operation.
The lines represented are Workers Compensation. The most-recent South Carolina filing we track is effective April 2026. Every row below links to its SERFF tracking number so the South Carolina regulator record can be verified.
