Seattle CPA planning that deserves a city page
This page is for Seattle clients whose records are too specific for a generic CPA location page: Washington B&O classification, retail sales tax, capital gains tax, stock compensation, 83(b) elections, customer sourcing, remote teams, K-1 income, and rental real estate.
We scope the engagement from the source records first. That means identifying whether the work is a return, B&O or sales-tax review, notice response, investor-ready close, audit/review/compilation, 83(b) project, or CFO reporting cleanup before we recommend a deliverable.
What we verify before scoping Seattle work
State tax posture
Washington does not impose a broad wage-based individual or corporate income tax, but the Department of Revenue still administers B&O, sales tax, capital gains, and other excise-tax rules that can affect Seattle businesses and owners.
Records we request early
B&O filings, sales-tax reports, customer sourcing, exemption certificates, marketplace reports, stock-comp documents, 83(b) support, brokerage detail, property schedules, K-1s, and prior Washington notices.
Seattle planning trigger
The page is most useful when federal planning, Washington receipts, equity compensation, and multistate income all appear in the same fact pattern.
Virtual service note
KAS CPA is virtual-first and does not claim a walk-in Seattle office. Seattle clients work through secure portal, video meetings, e-signature, and structured onboarding.

Seattle CPA FAQs
Do Seattle clients need Washington planning if there is no broad wage income tax?
Often, yes. Seattle clients may still have Washington B&O tax, sales tax, capital gains tax, payroll, property, or multistate sourcing issues that need to be coordinated with the federal return.
What Seattle records do you review before giving tax advice?
We usually start with B&O and sales-tax filings, customer-location detail, exemption certificates, payroll reports, equity-compensation documents, brokerage files, K-1s, rental schedules, and any Washington Department of Revenue notices.
Do you have a physical office in Seattle?
No. KAS CPA is a virtual-first CPA practice. Seattle clients use secure document exchange, video meetings, phone, e-signature, and structured onboarding.
Who is this Seattle CPA page best for?
