Washington taxes businesses in a way most owners have not met before. There is no state income tax, but there is a business and occupation tax charged on gross receipts rather than profit. Finkeepers provides bookkeeping services Seattle businesses can build on, designed around that difference rather than adapted to it afterwards.
We support startups, small businesses and established firms across Seattle, Bellevue, Redmond, Kirkland and the wider Puget Sound region. Accounting services Seattle businesses need are handled by a dedicated team, not a rotating pool. Bookkeeping services Seattle owners rely on should reflect Washington rules from the first month.
A small business accountant Seattle owners can rely on needs to understand B and O classifications, because the rate you pay depends on which activity your revenue falls under. Getting the classification wrong is one of the most common and most expensive errors we correct. A small business accountant Seattle firms trust has to get this right every quarter.
Why it matters: gross receipts taxation means you owe B and O tax whether or not the business made a profit that period. A loss-making quarter still carries a liability, which catches out owners arriving from income-tax states. What is the washington b and o tax is the first question almost every relocating owner asks us.
How it works: revenue is coded by B and O classification at entry, so the quarterly return is produced from the ledger rather than reconstructed. Seattle payroll expense tax is tracked monthly where the threshold applies, and WA Cares deductions run alongside standard payroll.
The bottom line: Washington rules applied correctly, every month. Explore our bookkeeping services, review payroll services, or book a free consultation.
Washington does not tax income, but it does tax revenue. Finkeepers delivers bookkeeping services Seattle owners can trust, covering B and O classification, Seattle payroll expense tax bookkeeping, and reporting that arrives before you have to ask for it.
Washington’s tax structure creates specific problems that do not exist elsewhere. Below are the four situations where Seattle and Puget Sound businesses most often need help.
From B and O classification to Seattle payroll expense tax, every deliverable Washington businesses need, handled by a dedicated Finkeepers team. Whether you run a single office or several Puget Sound locations, the scope adjusts. Bookkeeping services Seattle businesses need begin with correct classification.
Every revenue line coded to the correct business and occupation classification as it is recorded, so the quarterly return is generated from the ledger rather than reconstructed. Small business credit applied where the threshold allows.
Seattle payroll expense tax tracked monthly against the threshold, plus Washington Paid Family and Medical Leave premiums, WA Cares Fund contributions, and workers compensation rates applied by risk classification.
Bank and card reconciliations, transaction coding, accruals and month-end close completed on schedule. GAAP-compliant statements prepared for lenders, investors and your own decision making.
Quarterly B and O returns, annual business licence renewal, and city-level filings where they apply. Records maintained to the standard a Washington Department of Revenue review expects.
Whether you run on QuickBooks, Xero, NetSuite, Sage or Gusto, Finkeepers works fluently across every leading US accounting platform. Certified experts, seamless integration, and no disruption to how your business already runs.




























Most providers keep pricing behind a discovery call. We would rather you knew before you called. Seattle pricing tracks transaction volume and how many B and O classifications apply, because that is what drives the work. How much do bookkeeping services cost in seattle depends on those two factors more than on revenue.
Business profile | B and O classifications | Typical monthly range |
Sole trader or early stage | 1 | $350 – $650 |
Growing small business | 1 – 2 | $650 – $1,100 |
Established business | 2 – 3 | $1,100 – $1,900 |
Multi-entity or payroll tax threshold | 3+ | Scoped individually |
Quarterly B and O filing is included rather than charged separately, because the data is already captured monthly. There are no setup fees, no long-term contracts, and no charge for the initial assessment.
| Local CPA firm | Finkeepers |
Monthly cost | Often billed hourly, so the figure moves | Fixed monthly fee agreed in writing |
B and O classification | Usually correct, but reviewed quarterly | Coded at entry, checked every month |
Books closed by | Varies, frequently after the 15th | 10th business day, every month |
Coverage when absent | Work stops during leave or illness | A pod, so continuity is built in |
Review layer | Often one person checks their own work | Preparer, reviewer, and manager sign-off |
Data security | Depends on internal controls | ISO 27001:2022 certified, independently audited |
A local firm is the right answer when you need someone physically present for a state audit or a complex one-off matter. For monthly bookkeeping and quarterly B and O filing, the review layer and fixed pricing usually matter more than proximity.
Built on ISO 27001:2022 certified security, US-trained accountants, and a leadership team of industry veterans, Finkeepers carries the trust markers Washington business owners look for before handing over financial records.
Independently audited information security meeting the highest international standards. Not a badge we designed ourselves.

US businesses stay with Finkeepers long-term because of consistent, reliable, expert financial partnership.
Every Washington business earns across a different mix of B and O classifications, and so does our approach. Share your details and get a personalized plan built around your revenue structure and stage of growth. A small business accountant Seattle owners can reach directly, every month.
*No obligations. Just fast, expert bookkeeping insights tailored for your Seattle business.
Bookkeeping services Seattle businesses use typically cost between $350 and $1,900 per month, driven by transaction volume and how many business and occupation classifications your revenue falls under. Quarterly B and O filing is included rather than charged separately. Finkeepers offers transparent pricing with no setup fees and no long-term contract.
The business and occupation tax is charged on gross receipts rather than net profit, which means a Washington business owes it whether or not the period was profitable. Rates differ by classification, so retailing, wholesaling and service activity are each taxed differently. A small business credit reduces or eliminates the liability below a defined threshold.
The main classifications are retailing, wholesaling, manufacturing and service and other activities, each carrying its own rate. A business earning across more than one must allocate revenue between them. Misallocation is the most common Washington bookkeeping error we correct, and getting b and o tax classifications wrong changes the liability in both directions.
Yes. Seattle payroll expense tax bookkeeping is included where the business approaches or exceeds the payroll threshold. We track the position monthly rather than annually, so the obligation is visible before it is triggered rather than discovered afterwards, alongside WA Cares and Paid Family and Medical Leave contributions.
Most businesses operating in Seattle need both a Washington state business licence and a Seattle business licence tax certificate. Renewal dates differ, and city-level filing sits separately from the state B and O return. Both are tracked as part of the engagement.

What we offer instead is a dedicated team, ISO 27001:2022 certified security, and books closed by the 10th business day, every month.
