Who it's for
Built for Seattle.
Seattle CPA firms tend to specialize. Here's who we're built for:
- Tech workers with RSUs and startup equity navigating vesting, timing, and Washington's capital gains tax on the eventual sale
- Seattle small businesses and retail or service operators now weighing whether Seattle city B&O tax applies to them alongside the state B&O tax
- Startups and freelancers who need a tax preparer fluent in equity compensation, not just W-2 income
- Anyone comparing accountants in Seattle Washington who wants a licensed CPA's name behind the return, not a seasonal preparer

Book ConsultationWhy remote works here
Why Seattle clients work with us remotely.
Seattle's commercial rents are part of why a lot of local CPA firms charge what they charge. We don't carry a downtown lease, a parking budget, or a reception desk — so a return that runs $250 at a Pioneer Square firm can start at $80 here, from the same Washington State Licensed CPA doing the work. If you searched cpa seattle looking for that comparison, that overhead difference is the whole story. You never need to come into an office; everything moves through an encrypted client portal and scheduled video or phone calls.
That matters more in Seattle than almost anywhere else in the state, because so much of the client base here is remote-first by nature already. If you're a startup founder who never leases office space, or a tech employee who works from three cities a year, a CPA who insists on an in-person meeting is solving a problem you don't have.
The tax landscape
Seattle's tax stack: state B&O, city B&O, and capital gains
Every Seattle business already owes Washington's state Business & Occupation (B&O) tax — a tax on gross receipts, not net profit, with no deduction for expenses. Rates depend on classification: 0.471% for retailing, 0.484% for wholesaling and manufacturing, and a tiered rate for Service & Other Activities that took effect October 1, 2025 — 1.5% below $1 million in prior-year gross income, 1.75% from $1 million to just under $5 million, and 2.1% at $5 million and above. A Small Business B&O Tax Credit can reduce or zero out the state tax for the smallest filers, which is worth checking before assuming you owe anything.
Seattle then adds its own city B&O tax on top, and it changed materially on January 1, 2026 under the voter-approved "Seattle Shield" measure. The filing and exemption threshold jumped from $100,000 to $2,000,000 in annual taxable gross revenue, with a matching $2 million standard deduction for businesses above it. Rates rose too: retail, wholesaling, and manufacturing activities now pay 0.342% (up from 0.222%), while service-based businesses pay 0.658% (up from 0.427%). If your gross revenue is comfortably under $2 million, the practical effect of Seattle Shield is that you likely owe Seattle no city B&O at all — but confirm your specific filing obligation rather than assume it.
For individuals — especially the RSU and startup-equity holders concentrated in this city — Washington's capital gains tax is the number that actually moves. It applies at 7% on the first $1,000,000 of taxable gain above a standard deduction ($278,000 for 2025, the most recently published figure; the Department of Revenue had not posted a 2026 inflation-adjusted number as of this writing) and 9.9% on taxable gain above $1,000,000. It's a state-level tax with no Seattle-specific add-on, but it disproportionately touches the exact profile of client concentrated in this city: someone whose net worth is mostly unvested or recently-vested equity.
Washington and city tax rates, classifications, and thresholds on this page reflect our research of official Washington Department of Revenue and city finance department sources as of August 2026. Several of these figures changed in 2025 and 2026 legislative and rate-setting cycles and can change again — confirm your exact rate and threshold with the Washington Department of Revenue, the relevant city finance office, or on a consultation before filing.
