Washington taxes through the Washington Department of Revenue at a 6.5% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in sales. Filing runs monthly, quarterly, or annually by liability. Because Washington runs an annual bracket, low-volume insurance agencies can go twelve months between returns — which is exactly how long a liability account can drift before anyone looks at it.
Employer registration runs through the Washington Employment Security Department, and the entity is registered with the Washington Secretary of State. No income tax, but the Business and Occupation tax applies to gross receipts by activity classification and is reported alongside sales tax.

Premium trust funds in Washington
Where an agency collects premium from an insured before remitting it to a carrier, that money is generally held in a fiduciary capacity under Washington law, and the requirement to keep it separate from operating funds is a licensing condition rather than an accounting preference. The practical failure is gradual: premium sits in the operating account, is available, gets used, and is replaced from the next month's collections — which works until a month is short. Keeping a distinct premium account reconciled against what is owed to each carrier is what makes that impossible rather than merely unlikely. The agency entity is registered with the Washington Secretary of State and employer accounts run through the Washington Employment Security Department, while the Washington Department of Revenue handles anything taxable the agency sells alongside coverage — no income tax, but the Business and Occupation tax applies to gross receipts by activity classification and is reported alongside sales tax.
How Washington treats commission income
Agency commission is taxable business activity in Washington, which is unusual and consistently missed. The Business and Occupation (B&O) Tax applies to gross receipts, with no deduction for cost of goods, labour, or any other expense — and commission income is squarely within that, where a state with an ordinary sales tax on goods would reach none of it. the rate depends on the activity classification — retailing, wholesaling, service, manufacturing — and a business doing more than one reports under more than one. It is filed alongside sales tax on the same return. For an agency that means because there is no deduction for costs, a business with thin margins pays B&O in years it loses money. Revenue has to be split by activity classification in the books, or the return is guesswork, and it means the commission statements have to be recorded gross rather than as whatever the carrier deposited.
Are your services taxable in Washington?
Whether insurance agencies services are taxable in Washington is the question that catches people out — states differ enormously, and several have been broadening what counts. No income tax, but the Business and Occupation tax applies to gross receipts by activity classification and is reported alongside sales tax. We code service revenue separately from any product revenue so the treatment is explicit rather than assumed.
Registering to do business in Washington
Registering to do business in Washington runs through the Washington Secretary of State, with tax accounts through the Washington Department of Revenue and employer accounts through the Washington Employment Security Department. Washington treats these as wholly independent, so being in good standing with one says nothing about the others — and the sales tax account is the one that accrues a real balance while you are not looking.
