Insureon publishes no Washington figure, so the ranges on this page use its national medians. Labour and medical costs are high here, the Seattle area holds a large professional services base, and wildfire and smoke exposure east of the Cascades sits on the property side of the book. The thing that makes Washington unusual is workers’ compensation, which you cannot buy from a private insurer here at all. Below are the 2026 numbers by coverage, trade and headcount, what shapes them, and the levers that move a Washington premium. For the 50-state picture, see average business insurance cost by state.
Average business insurance cost in Washington by coverage
The table shows what a Washington business of two to five people in a middling risk class pays for the three policies most small businesses carry. Professional liability, also sold as errors and omissions, responds when a client says your work cost them money. A business owner’s policy adds property cover on your own equipment.
| Coverage | Typical monthly | Typical annual | What it covers |
|---|---|---|---|
| General liability ($1M per occurrence) | $30–$60/mo | $360–$720/yr | Third-party injury and property damage; the policy a client or landlord asks for by name. |
| Professional liability (E&O) | $75–$150/mo | $900–$1,800/yr | Claims that your advice or work cost a client money, legal defence included. |
| Business owner’s policy (BOP) | $50–$100/mo | $600–$1,200/yr | General liability plus commercial property, usually with business-interruption cover. |
| Hiscox advertised starting price | from $22.50/mo | from $270/yr | E&O from $22.50, general liability from about $29, a BOP from about $42. |
Estimates from Insureon’s national published medians, since Insureon publishes no Washington figure, for a business of two to five people at standard $1M/$2M limits. Not quotes; your insurer prices your specific business. Hiscox writes coverage in 49 states plus Washington DC (not Alaska).

Most Washington businesses begin with general liability because somebody else demands it: a South Lake Union landlord in Seattle who wants a certificate before handing over keys, or a Tacoma property manager who will not let a cleaning crew into a building without one. A business owner’s policy earns its higher price once you own equipment, stock or a lease, because it bundles property cover for less than two separate policies. Our guide to general liability vs professional liability vs BOP explains which to buy first.
Washington business insurance cost by trade
Your trade moves the premium more than your address: a consultant who never leaves the laptop is a cheaper risk than a contractor, and insurers price that gap with a risk class. Twelve common trades in Washington, two to five people, $1M/$2M limits.
| Trade | General liability | Business owner’s policy |
|---|---|---|
| Consultant | $21–$43/mo | $37–$73/mo |
| IT or software developer | $25–$49/mo | $28–$55/mo |
| Accountant or bookkeeper | $20–$40/mo | $36–$72/mo |
| Photographer or videographer | $19–$39/mo | $28–$57/mo |
| Real estate agent | $22–$44/mo | $35–$70/mo |
| Online store (e-commerce) | $28–$56/mo | $57–$114/mo |
| Personal trainer or fitness | $19–$39/mo | $36–$71/mo |
| Cleaning or janitorial | $32–$64/mo | $46–$92/mo |
| Landscaping or lawn care | $34–$68/mo | $57–$113/mo |
| Auto repair shop | $36–$72/mo | $90–$180/mo |
| Restaurant or café | $94–$188/mo | $151–$302/mo |
| General contractor | $108–$216/mo | $50–$100/mo |
Estimates from Insureon’s published medians for each business type for Washington, for two to five people at the standard $1M/$2M limits. Not quotes.
Insureon publishes no separate figure for roofing and other high-risk construction, so they are left out of the table. The trade in the second row has its own Washington guide: software developer insurance in Washington.
Cost by business size
Headcount matters too: every hire is another pair of hands that can drop a client’s server or leave a wet floor unsigned, and Insureon says more staff and more revenue generally mean higher premiums. It publishes no prices by headcount, so the table below only shows where in the Washington range a business of each size is likely to sit.
| Business size | General liability |
|---|---|
| Just me | $30–$45/mo |
| 2 to 5 people | $30–$60/mo |
| 6 or more people | $45–$60/mo |
Estimates from Insureon’s published medians for Washington, not quotes. No source publishes prices by headcount, so we show the lower half of the range for a one-person business under $100k in revenue, the whole range for two to five people, and the upper half for six or more. Larger businesses often pay more than this, especially for workers’ comp.
Why Washington costs what it does
Insureon publishes no Washington figure, so we cannot say how far Washington sits from the national average, and the ranges on this page use national figures. Three forces can push a Washington quote above them.
- High labour and medical costs. Liability claims are settled in local money. Repair labour, replacement services and medical treatment all cost more in Washington than the national average, so the same accident closes at a higher number and carriers price for it up front.
- A dense Seattle-area professional services base. Software, consulting and design firms cluster around Seattle and the Eastside, which raises both commercial density and the value of the contracts a professional liability claim can put in dispute.
- Wildfire and smoke exposure east of the Cascades. The property half of a Washington BOP prices for wildfire and smoke damage in the drier country east of the mountains.
What Washington requires
The Office of the Insurance Commissioner (OIC) regulates insurers in Washington. Workers’ compensation cannot be bought from a private insurer here at all: it comes from the state fund run by the Department of Labor and Industries, or through certified self-insurance for employers who qualify. That puts it outside the rest of your business insurance, so the ranges on this page do not include it and a quote from Hiscox or any other private carrier will not either.
Contractors have a second set of obligations. To work in Washington a contractor must register with Labor and Industries, and registration requires both a surety bond and liability insurance, so for that trade the general liability policy on this page is a condition of trading rather than a nicety. Budget for the business and occupation tax as well: Washington levies no state income tax but does tax gross receipts. Rules change, so confirm current specifics with the body named before you rely on this page.
How to lower your premium in Washington
These are the levers that most often bring a Washington premium down.
- Get the classification right. A bookkeeper rated as a general consultant pays for a risk they do not carry, so describe the work precisely.
- Quote real revenue. Premiums scale with revenue, and quoting projections means overpaying until renewal.
- Buy the limits the contract asks for, not more. $1M/$2M satisfies nearly every Washington lease and vendor agreement; see $1 million liability insurance cost for what higher limits add.
- Take a higher property deductible. Wildfire, smoke and storm losses sit on the property side of a BOP, and lifting that deductible is the most direct way to bring the property half down.
- Bundle into a BOP. If you need property cover at all, a BOP is almost always cheaper than two separate policies.
- Stay claims-free and pay annually. Carriers price a clean loss history lower at renewal, and most charge less for one annual payment than for twelve.
Where these numbers come from
The figures at the top of this page and in the main cost table come from the same data as our cost estimator, so the two always agree. The starting point is the median premium that Insureon, an online insurance agency, publishes for its small business customers (see its Washington page). We adjust it for the state using Insureon’s state medians, and show the band that Insureon’s own price distribution says most businesses fall in. Every figure is an estimate, not a quote. The full method and source list is on the estimator page.
Frequently asked questions
How much is business insurance in Washington per month?
A Washington business of two to five people typically pays about $30–$60 a month for general liability, $75–$150 for professional liability and $50–$100 for a business owner’s policy, on national figures, since Insureon publishes none for Washington.
Is business insurance more expensive in Washington than the national average?
We cannot say for sure. Insureon publishes no Washington figure, so the ranges on this page use national figures: about $30–$60 a month for general liability for a business of two to five people. High labour and medical costs, a dense Seattle-area professional services base and wildfire exposure east of the Cascades can push a Washington quote above that.
Do I need workers’ compensation in Washington?
Yes, and you cannot buy it from a private insurer. Washington workers’ compensation comes from the state fund run by the Department of Labor and Industries, or through certified self-insurance if you qualify, so it sits outside the policies priced on this page. Labor and Industries publishes the current rules.
How much does $1 million liability insurance cost in Washington?
A $1 million per occurrence, $2 million aggregate general liability policy costs a typical Washington business of two to five people about $30–$60 a month, or $360–$720 a year. That is the limit most landlords and contracts ask for; a one-person business under $100k in revenue pays closer to $30–$45 a month, on national figures.
What is the cheapest business insurance in Washington?
General liability on its own is the cheapest policy for most Washington businesses, and desk-based businesses such as a one-person consultancy are among the cheapest to insure. On Insureon’s national figures (it publishes none for Washington), a one-person consultancy pays about $21–$32 a month for general liability.
Do I have to buy through you?
No. This site publishes cost guides and earns a commission if you get a quote through a partner link. We are not an insurer or a broker, we do not sell your details, and a quote costs you nothing and commits you to nothing.
