If you are a Washington sole proprietor with no workers, you owe no mandatory workers compensation premium, because you are not treated as a worker and are left off the state system by default. The day you hire anyone, that changes: you must open an account with the Department of Labor and Industries (L&I) and cover your workers from their first hour, though you still are not required to cover yourself. If you want the state fund to pay your own on-the-job injuries, you can opt in by filing an elective-coverage form.
Who this is for: Washington sole proprietors, from solo trades and freelancers to owners about to hire their first helper.
The short version
- A solo sole proprietor with no workers owes no mandatory premium and is left off by default.
- You can elect coverage for yourself by filing the state's elective-coverage form.
- Hire anyone and you must open an L&I account and cover the worker from the first hour.
- You buy only from the state fund; there is no private carrier to shop in Washington.
- A client asking for proof of your L&I account status is common; being registered lets you show it fast.
Do you need it, and do you want it?
Two different questions sit inside this. The requirement is about your workers: none, and there is no mandatory premium; one or more, and coverage is mandatory from their first hour. The choice is about you: as a sole proprietor you are not a worker, so the state fund would not pay your own injuries unless you elect coverage. Some owners in low-risk desk work skip electing and rely on their own health and disability cover; owners doing physical or hazardous work often elect in because a serious on-the-job injury is exactly what the state fund is designed to pay for.
What applies to you
| Your situation | Mandatory coverage? | What to do |
|---|---|---|
| Solo, no workers | No mandatory premium | Optional: file the elective-coverage form to cover your own injuries |
| You plus one or more workers | Yes, for the workers | Open an L&I account and report the workers' hours; you may also elect coverage for yourself |
| Using 1099 helpers | Often yes | A helper is treated as your worker unless a strict state test is met, so confirm status before you rely on it |
If you only need proof for a client
A common reason a solo owner looks into coverage is that a general contractor or customer wants proof of insurance. In a private-market state you might buy a small owner-only policy just to produce a certificate. Washington works differently: because you buy from the state fund, what a contractor usually wants to see is that you have an active L&I account in good standing, which they can even verify online. If you have no workers and have not elected coverage, you may not have an account, so ask the contractor exactly what they need, and if it makes sense, elect coverage so you can show an active account. It is also worth carrying stop-gap employers liability once you have staff, since the state fund does not pay to defend a lawsuit.
A Spokane example
Illustrative, not a quote. A Spokane landscaper runs solo as a sole proprietor and owes no mandatory premium. When he lands a commercial account that requires proof of coverage, he elects owner coverage with L&I so he has an active account to show, and because his work is physical, that also means the state fund would pay if he is hurt on a job. When he later hires a seasonal crew member, he reports those hours and covers the worker from day one. See our workers comp for landscapers page.
Real questions Washington owners ask
Do I need workers comp as a Washington sole proprietor?
Not for yourself if you have no workers, because a sole proprietor is not treated as a worker. The moment you hire anyone, you must open a state account and cover that worker from the first hour.
Can I cover myself as a sole proprietor?
Yes, by choice. You file the state's elective-coverage form to opt in, then report your hours, and the state fund will pay your own on-the-job injuries. Without electing, you are left off the system.
Where do I buy it if I hire someone?
Only from the state fund at Labor and Industries. Washington does not have private workers comp carriers, so you open an L and I account and report your worker's hours each quarter rather than shopping for a policy.
A general contractor wants proof of coverage. What do I show?
In Washington, contractors usually want to see that you have an active L and I account in good standing, which they can verify online. If you have no workers and no account, ask what they need and consider electing coverage.
Do 1099 helpers count as my workers?
Often yes. Washington treats a helper as your covered worker unless a strict state test is fully met, and the test is even tougher in the trades. Do not assume a 1099 label removes the duty to cover them.
I do risky physical work. Should I elect coverage?
Many owners in physical trades do, because the state fund pays medical care and lost wages for an on-the-job injury. If you skip it, you are relying on your own health and disability insurance for a work injury.
What does the state policy not cover for me?
It does not defend you in a lawsuit. Once you have workers, adding stop-gap employers liability to your general liability policy covers your legal defense if you are sued over a workplace injury.
Why Washington owners choose Morrow
- We shop the right market for you. In Washington, workers' compensation is sold only through the state fund at the Department of Labor and Industries (L&I), with no private carriers to shop, so we help you open and run your L&I account correctly and place the stop-gap employers liability and other business coverages the state fund does not include.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
