Commercial insurance rate filings by U.S. state (2026)
Every commercial-insurance line is regulated state by state. Workers' comp loss costs are filed bureau-wide (NCCI in most states, independent bureaus in CA / NY / PA / NJ / MA / MI / MN). Commercial auto + general liability + property + BOP are filed by ISO and adopted by carriers.
