How Workers' Comp rates are set in South Dakota
South Dakota runs a private Workers' Comp market. Rate filings are reviewed by the South Dakota Division of Insurance. We track 1 distinct classification(s) for South Dakota across 2 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 Dakota 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 Dakota filing we track is effective July 2025. Every row below links to its SERFF tracking number so the South Dakota regulator record can be verified.
