Why a state page cannot give a universal answer

Coverage can depend on the employer’s industry, number and classification of workers, entity structure, locations, contracts, out-of-state work, and whether an exception or self-insurance route applies. Treat this page as a document and verification checklist, not as a final compliance conclusion.

Official sources

Continue carefully

Use the preparation estimator to organize operating factors, then compare the actual requirements and policy wording with a licensed professional.
