Business insurance in Washington
If you run a business in Washington, your insurance setup works differently than in most states. You cannot shop workers' comp on the open market — coverage comes through the state's L&I fund the moment you hire your first employee. That leaves gaps a private carrier would normally cover, so you'll pair general liability, a BOP, commercial auto, and stop-gap employers liability to protect yourself. Add earthquake and wildfire exposure to the mix, and getting the right combination matters. Compare quotes before you commit.

Washington requirements at a glance
- Workers' comp
- Required as soon as a business has any employee — including part-time and most seasonal/casual labor, with no minimum-employee threshold (one worker triggers it). Coverage is purchased through the state's Department of Labor & Industries (L&I). Sole proprietors, partners, and certain corporate officers/LLC members may be exempt or elect optional coverage; large, financially qualified employers may apply to self-insure instead.
- WC market
- Monopolistic — buy through the state fund only
- Min. auto liability
- 25/50/10 ($25,000 bodily injury per person / $50,000 bodily injury per accident / $10,000 property damage per accident)
- State regulator
- Washington State Office of the Insurance Commissioner (OIC)
What businesses in Washington need
Most Washington businesses build coverage from a few core lines. Monopolistic WC through L&I means private carriers cannot sell workers' comp in Washington, and L&I coverage does NOT include employers liability — so businesses should add "stop-gap" employers liability coverage to their commercial general liability or BOP policy to fill that gap (a common oversight). Washington also carries meaningful catastrophe exposure: Cascadia-subduction earthquake risk statewide (quake damage is excluded from standard property policies and needs a separate endorsement) and rising wildfire risk in central and eastern parts of the state.
- • General liability — third-party injury and property-damage claims. See the cost guide.
- • Business owner's policy (BOP) — bundles liability and property. See the BOP cost guide.
- • Workers' compensation — Required as soon as a business has any employee — including part-time and most seasonal/casual labor, with no minimum-employee threshold (one worker triggers it). Coverage is purchased through the state's Department of Labor & Industries (L&I).

- • Commercial auto — required for business vehicles (Washington minimum: 25/50/10 ($25,000 bodily injury per person / $50,000 bodily injury per accident / $10,000 property damage per accident)).
- • Professional liability (E&O) and cyber — for advice-based and data-handling businesses.

Frequently asked questions
Can I buy workers' compensation insurance from a private company in Washington?
No. Washington is one of only four monopolistic workers'-comp states (with North Dakota, Ohio, and Wyoming), so employers must buy coverage from the state fund run by the Department of Labor & Industries (L&I) — private insurers are not allowed to sell WC here. The only alternative is qualifying as a certified self-insured employer, which is generally limited to large, financially strong companies. Because L&I coverage excludes employers liability, most businesses add a separate 'stop-gap' employers liability endorsement through a private carrier.
What are the minimum car insurance requirements for a business vehicle in Washington?
Washington requires minimum auto liability limits of 25/50/10 — $25,000 for bodily injury per person, $50,000 for bodily injury per accident, and $10,000 for property damage per accident. These are the same state minimums that apply to personal vehicles, but commercial vehicles and any vehicle used for business should typically carry a commercial auto policy with substantially higher limits, since a single serious accident can easily exceed the state floor. Confirm current requirements with the Washington State Department of Licensing.
