Washington prices small business insurance above the national average. Labour and medical costs are high, 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) | $37–$65/mo | $450–$780/yr | Third-party injury and property damage; the policy a client or landlord asks for by name. |
| Professional liability (E&O) | $49–$85/mo | $590–$1,023/yr | Claims that your advice or work cost a client money, legal defence included. |
| Business owner’s policy (BOP) | $69–$120/mo | $830–$1,439/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. |
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 |
|---|---|---|
| Consulting / professional services | $30–$52/mo | $55–$96/mo |
| IT / software development | $32–$55/mo | $59–$102/mo |
| Accounting / bookkeeping | $34–$58/mo | $62–$108/mo |
| Photography / video | $34–$58/mo | $62–$108/mo |
| Real estate / property | $36–$62/mo | $66–$114/mo |
| E-commerce / online retail | $39–$68/mo | $73–$126/mo |
| Fitness / personal training | $43–$75/mo | $80–$138/mo |
| Cleaning / janitorial | $45–$78/mo | $83–$144/mo |
| Landscaping / lawn care | $51–$88/mo | $93–$162/mo |
| Auto services / repair | $52–$91/mo | $97–$168/mo |
| Restaurant / food & beverage | $54–$94/mo | $100–$174/mo |
| Contractor / general trades | $66–$114/mo | $121–$210/mo |
Roofing and other high-risk construction runs $90–$156 a month for general liability alone, well past the bottom of the table. The trade in the second row has its own Washington guide: software developer insurance in Washington.
Cost by business size
Headcount is the second big lever: every hire is another pair of hands that can drop a client’s server or leave a wet floor unsigned, so general liability scales with payroll. Trade is held constant below.
| Business size | General liability |
|---|---|
| Just me | $30–$52/mo |
| 2 to 5 people | $37–$65/mo |
| 6 to 20 people | $58–$101/mo |
| 21 to 50 people | $90–$156/mo |
| 51+ people | $135–$234/mo |
Why Washington costs what it does
Washington prices about 11 percent above the national average in our state table, and three forces explain the gap.
- 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, an exposure that has grown expensive enough to show up in state rates.
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
Together these can move a Washington premium by a third or more.
- 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 ranges on this page take the national averages of $45 a month for general liability, $59 for professional liability and $83 for a BOP, and scale them by Washington’s state multiplier of 1.111, about 11 percent above the national average, and each trade’s risk class. It is the same arithmetic our small business insurance cost calculator runs, so the two agree. The low and high ends apply a 0.75 to 1.30 spread, roughly the gap between the cheapest and dearest carrier quoting the same business. The national ranges are in how much small business insurance costs.

Frequently asked questions
How much is business insurance in Washington per month?
A Washington business of two to five people typically pays about $37–$65 a month for general liability, $49–$85 for professional liability and $69–$120 for a business owner’s policy. Hiscox advertises coverage from $22.50 a month and quotes online in about five minutes.
Is business insurance more expensive in Washington than the national average?
Yes, by about 11 percent. General liability that runs $34–$58 a month nationally runs $37–$65 in Washington. High labour and medical costs, a dense Seattle-area professional services base and wildfire exposure east of the Cascades lift the state above the national line.
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 $37–$65 a month, or $450–$780 a year. That is the limit most landlords and contracts ask for; a sole proprietor in consulting or IT pays closer to $30–$52 a month.
What is the cheapest business insurance in Washington?
General liability on its own is the cheapest policy for most Washington businesses, and a one-person consultancy or software shop is the cheapest profile to insure. Hiscox advertises professional liability from $22.50 a month and general liability from about $29, and a Washington premium sits a little above that floor.
Do I have to buy through you?
