Maryland commercial insurance rate filings (2026)
Every commercial-insurance carrier writing business in Maryland files its loss costs and rating values with the state's insurance regulator — the primary-source records that drive every commercial quote in Maryland. This page summarizes the 1 active filings we track for Maryland across 1 line(s) of business and 1 classification(s).
How Workers' Comp rates are set in Maryland
Maryland runs a private + state fund Workers' Comp market. Rate filings are reviewed by the Maryland Insurance Administration. We track 1 distinct classification(s) for Maryland 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 Maryland 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 Maryland filing we track is effective January 2026. Every row below links to the filing it was taken from so the Maryland regulator record can be verified.
Workers' Compensation covers medical bills and lost wages for Maryland employees injured on the job — mandatory in Maryland once you have staff.
