How Workers' Comp rates are set in Iowa
Iowa runs a private Workers' Comp market. Rate filings are reviewed by the Iowa Insurance Division. We track 1 distinct classification(s) for Iowa 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 Iowa 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 we track are Workers Compensation. The most-recent Iowa filing we track is effective January 2026. Every row below links to the filing it was taken from so the Iowa regulator record can be verified.
Workers' Compensation covers medical bills and lost wages for Iowa employees injured on the job — mandatory in Iowa once you have staff.
