Wash. Admin. Code § 296-17-31004
(2) I hire contractors to perform work for me. Do I need to be concerned about premiums on their work? Yes. There are two ways you may be liable for premiums on the work they do.
First, they may be "workers" for whom you are required to report and pay premiums. The law defines worker to include both your employees and independent contractors you hire, when the essence of the contract is personal labor. See RCW 51.08.070, 51.08.180, 51.08.181, and 51.08.195 for more guidance about when independent contractors will be considered workers.
Second, the Industrial Insurance Act imposes premium liability on anyone who contracts with another to have work performed. Even if the contractor you hire is not your worker (for example, if the contractor uses one or more workers on the job), you could be liable for their premiums if they fail to pay.
(3) Is there any way for me to protect myself from being held liable for premiums owed by construction contractors I hire? Yes, if you are a registered construction contractor or licensed electrical or plumbing contractor, and you hire a registered construction contractor or a licensed electrical or plumbing contractor to do construction work that requires licensing or registration, you can protect yourself from being found liable for the premiums on the work that contractor does for you if:
(4) What does "in good standing" mean? For someone's account to be in good standing, they must:
(6) I use the same subcontractors over and over. Do I have to verify that they have an industrial insurance account in good standing every time I use them? No. In RCW 51.12.070 protection for construction contractors only requires that you have confirmed a subcontractor's account within a year prior to letting a contract. When you check out your subcontractors on the department's website or by calling your account manager, a confirmation number will be provided as proof you checked them out. This confirmation number is valid for one year from the time it is issued.
If you are notified by the department of labor and industries that a subcontractor's account is no longer in good standing, you may be liable for their industrial insurance premiums from the date of notification forward.
