Bookkeeping, Tax Preparation Support and Virtual CFO Services for Seattle Businesses

Washington charges no personal or corporate income tax, but that is not the same as low tax administration. The state B&O tax applies to gross receipts by classification: Service and Other Activities is taxed at 1.5% under $1 million in prior-year Washington revenue, 1.75% between $1 million and just under $5 million, and 2.1% at $5 million and above, while Retailing and Wholesaling sit near half a percent. Seattle then applies its own city B&O on top, with Service and Other Business Activities at 0.658% and Retail Sales, Retail Services and Wholesaling at 0.342% under the 2026-2032 city schedule, after the January 1, 2026 Seattle Shield changes moved the city filing threshold to $2 million in gross receipts with a matching standard deduction. Getting this right means classifying revenue lines correctly (a firm can owe more than one B&O classification on the same books) and keeping the multiple activities tax credit in mind if the same income is taxed twice. On top of B&O, the combined Seattle sales tax rate runs around 10.55%, so retail and some service invoices need sales tax tracked by location, not assumed at a flat state rate. Confirm your exact B&O classification and current city threshold with the Washington Department of Revenue and Seattle's Office of City Finance, since both bodies update rates and thresholds on their own schedules and your specific activity mix drives which numbers apply.

A Seattle business generally carries three separate registrations: a Washington State Business License (through the Department of Revenue's Business Licensing Service), a City of Seattle business license tax registration once gross Seattle receipts cross the current threshold, and, for anyone hiring, Washington Paid Family and Medical Leave and Paid Sick Leave payroll accounts alongside standard federal payroll filings. State B&O and sales tax are typically filed monthly, quarterly or annually depending on volume, with the Department of Revenue setting the frequency after registration. Seattle's own business license tax return follows a separate filing calendar set by the Office of City Finance, distinct from the state return, which is the detail that catches new Seattle businesses off guard when they assume one filing covers both. Washington's capital gains tax, which applies to individuals on long-term gains above an annually adjusted standard deduction, is filed with the Department of Revenue on a schedule tied to the individual return, not the business return, and only applies to the individual owner, not the entity itself. We build a filing calendar keyed to your actual registrations, so state B&O, city B&O, sales tax and payroll deadlines sit on one schedule instead of four separate ones you have to track by memory.

Seattle's business base skews toward software and cloud companies, from Eastside enterprise vendors to South Lake Union startups, where the bookkeeping work centers on deferred revenue, multi-state sales tax nexus as SaaS products sell beyond Washington, and R&D-heavy cost structures ahead of any first profitable year. Ecommerce sellers running Amazon FBA or Shopify storefronts out of Seattle and Kent-area warehouses need marketplace payout reconciliation and inventory accounting that a generic bank-feed setup does not capture. The region's aerospace supply chain, feeding into Boeing's Everett and Renton operations, brings job costing and long-cycle contract accounting questions that differ from a standard services business. Biotech and life sciences startups clustered around South Lake Union and the University of Washington corridor carry grant accounting and burn-rate reporting needs typical of pre-revenue, VC-backed companies. And the city's dense coffee, restaurant and hospitality scene deals with tip credit tracking, multiple point-of-sale integrations and Seattle's own minimum wage and paid leave rules layered on top of standard payroll. Each of these brings a different chart of accounts and a different set of numbers that actually matter month to month, which is why we build the books around the industry, not a template.

Documents move through a secure client portal rather than email attachments, so bank statements, payroll reports and receipts stay off inboxes and in one auditable trail your senior reviewer can follow. Bank and card feeds connect the same way they would with a local firm, through your accounting software's own bank-feed integrations, and reconciliation happens on the same monthly cadence a Seattle-based bookkeeper would run. We are not a Seattle office and we do not claim to be; we are a delivery team contracted to work your books, with senior review built into the process before anything reaches you. That structure works the same whether you are downtown, on the Eastside in Bellevue or Redmond, or south toward Kent and Tacoma, since none of it depends on being able to walk into an office.

Most Seattle small and mid-size businesses we see run QuickBooks Online or Xero as the general ledger, with Gusto, ADP or Rippling handling payroll for teams that range from a handful of people to fifty or more. Ecommerce sellers typically connect A2X or Link My Books to reconcile Amazon and Shopify payouts into the ledger, and SaaS companies increasingly layer on Stripe for billing and a forecasting tool like Runway or Mosaic once they raise a seed round. On the banking side, Seattle businesses commonly bank with national players like Chase and Bank of America downtown, alongside Pacific Northwest names such as WaFd Bank and HomeStreet Bank, and First Tech Federal Credit Union shows up often among the region's tech workforce and startups. Venture-backed companies that used to default to Silicon Valley Bank now largely bank with First-Citizens Bank (which acquired SVB's deposits and loans in 2023) or have split banking relationships across two institutions since the 2023 collapse. We connect to whichever stack you already run rather than asking you to switch, and we can also help migrate off a spreadsheet or an outgrown bookkeeping app if that is where you are starting from.

Pricing depends on transaction volume, the number of bank and card accounts, whether you need cash-basis or accrual bookkeeping, and whether payroll, sales tax filing or tax preparation support are bundled in. A Seattle service business with straightforward books costs less to maintain than an ecommerce seller reconciling three marketplaces or a startup tracking deferred revenue and a cap table. See our rate card for the current monthly ranges by business size and complexity, and expect a fixed monthly fee once we understand your volume rather than an hourly bill that punishes a busy month. Catch-up or cleanup work, common when a Seattle business has fallen behind on reconciliations or is untangling a prior bookkeeper's chart of accounts, is quoted separately once we can see the actual state of the books.

A full-time in-house bookkeeper or staff accountant in the Seattle metro area is one of the more expensive hires in the country for the role, reflecting the region's overall cost of labor; the Bureau of Labor Statistics publishes current metro-level wage data for bookkeeping, accounting and auditing clerks and for accountants and auditors, and it is worth checking the latest release directly since figures update each year. On top of base pay, a local hire adds payroll tax, benefits, Washington's Paid Family and Medical Leave employer contribution, and the ramp-up time of training someone on your specific books. A remote bookkeeping and accounting engagement replaces that with a fixed monthly cost, senior review built in, and no gap when someone takes vacation or leaves. It is not the right fit for every business, particularly one that wants a bookkeeper physically in the office each day, but for a Seattle company comfortable with a portal-and-call working relationship, the cost difference is usually significant enough to be the deciding factor on its own.

Send us your last few months of bank and card statements, your current accounting software login (or tell us if you are not on one yet), and a short description of how the business makes money. We will map your Washington and Seattle B&O classifications, confirm your current filing frequency with the state and city, and give you a fixed monthly quote before any work begins. Most Seattle engagements start with a books review to see what is clean, what needs a catch-up pass, and what your sales tax and B&O exposure actually looks like today, so nothing gets missed once monthly bookkeeping starts.
