Washington is one of four monopolistic states in the United States.
In these states, workers comp insurance coverage can only be bought through the state, usually known as a state fund.
In a monopolistic state there is no open competition and you cannot buy workers comp through a private insurance company.
In Washington, a work comp policy can only be bought thru the Washington State Fund.
If you are a Washington business owner or conducting work in Washington you must connect with the Washington Department of Labor and Industries (DL & I) to buy a workers compensation policy:
