No, you don’t have to register, but you can if you need proof of registration for bidding purposes. Non-employer operations, including independent operators and prospective bidders may register with the WSCC and receive an account number prior to establishing or commencing business.
In order to register and receive a WSCC account number, a non-employer operation must pay a $200 annual administrative fee. A non-employer operation registering for the first time must pay the full administrative fee regardless of how many days remain in the calendar year.
