Washington, WA CPA Services Built Around State-Specific Decisions
Washington CPA work for tech executives with substantial equity compensation, Boeing professionals, real estate investors with appreciated Seattle-area properties, and high-net-worth families navigating WA estate tax starts with the state tax posture, not just a city-name swap. Washington has no personal income tax on wages. For tax year 2025, the capital gains tax has a $278,000 standard deduction, then applies at 7% to the first $1 million of Washington taxable capital gains and 9.9% above $1 million. Washington's B&O tax is based on gross receipts, with rates that depend on classification and, for Service and Other Activities, prior-year taxable income.
For tech executives with substantial equity compensation, Boeing professionals, real estate investors with appreciated Seattle-area properties, and high-net-worth families navigating WA estate tax, the next layer is filing execution: No individual income tax return for wages. WA capital gains tax filed annually. Business and Occupation Tax is filed monthly or quarterly with the Washington Department of Revenue. We tie those mechanics to entity records, owner documents, payroll, sales tax, lender requests, and federal planning before a return, notice, or audit deadline narrows the options.
Local industry, ownership, funder, and residency facts shape the engagement scope. For attestation or other state-sensitive work involving Washington Nonprofit Audits, Washington 401(k) & Employee Benefit Plan Audits, Washington Single Audits (Uniform Guidance) for tech executives with substantial equity compensation, Boeing professionals, real estate investors with appreciated Seattle-area properties, and high-net-worth families navigating WA estate tax, we confirm CPA mobility, firm registration, and engagement-scope requirements before accepting the work.

Washington Nonprofit Audits
Washington charities with more than $3,000,000 in average annual gross revenue over the prior three years generally must obtain an independent audit. In the $1,000,000-to-$3,000,000 tier, the organization may publish either a professionally prepared federal return or an audit; a review is not mandated. Federal Single Audit requirements under 2 CFR Part 200 apply separately when federal award expenditures are $1,000,000 or more in a fiscal year.
Washington 401(k) & Employee Benefit Plan Audits
Washington plan sponsors filing Form 5500 generally require an ERISA-compliant audit when the plan has 100 or more participants with account balances at the start of the plan year. We perform full-scope and §103(a)(3)(C) limited-scope benefit plan audits for 401(k), 403(b), and defined-benefit plans across Washington, including plans sponsored by Microsoft (Redmond), Amazon (Seattle), Boeing (Renton; Everett), Costco (Issaquah), Starbucks (Seattle), Nordstrom, T-Mobile (Bellevue), and the WA tech and biotech sectors.

Washington (WA) Tax & Business Landscape
Key Washington Tax Numbers. Personal income tax on wages: none. For tax year 2025, the capital gains tax has a $278,000 standard deduction; 7% applies to the first $1 million of Washington taxable capital gains and 9.9% applies above $1 million. The B&O tax is based on gross receipts; current Service and Other Activities rates are 1.5%, 1.75%, or 2.1% based on prior-year taxable income in that classification. Sales and use tax: 6.5% state, with combined rates approximately 10% in Seattle. For deaths on or after July 1, 2026, the estate-tax filing threshold and exclusion amount are $3 million, with rates up to 20%. For 2026, the Seattle JumpStart payroll tax applies when a business had at least $9,074,409 of Seattle payroll in 2025 and pays at least one employee $194,452 or more in 2026; rates range from 0.746% to 2.557%. No PTE election applies because Washington has no individual income tax to credit against. For tech executives with substantial equity compensation, Boeing professionals, real estate investors with appreciated Seattle-area properties, and high-net-worth families navigating WA estate tax, these numbers matter most when entity structure, owner compensation, residency, property, or investment decisions change the federal and state result.
Filing Mechanics. No individual income tax return for wages. WA capital gains tax filed annually. Business and Occupation Tax is filed monthly or quarterly with the Washington Department of Revenue. WA estate tax is filed on Form REV 85 0050. We use those mechanics to build a filing calendar and document request list for tech executives with substantial equity compensation, Boeing professionals, real estate investors with appreciated Seattle-area properties, and high-net-worth families navigating WA estate tax before deadlines compress the planning options.
WA Estate Tax — A Major Planning Issue. For deaths on or after July 1, 2026, Washington's estate-tax filing threshold and exclusion amount are $3 million, with graduated rates up to 20%. Washington homeowners with appreciated Seattle-area real estate, retirement accounts, and tech equity may face state estate tax even when no federal estate tax is due, so the date of death, domicile, asset situs, deductions, and elections all matter.
Washington Economy & Who We Serve. Washington's economy is dominated by technology — Microsoft (Redmond), Amazon (Seattle), Costco (Issaquah), Starbucks (Seattle), T-Mobile (Bellevue), Expedia, Nordstrom — plus aerospace anchored by Boeing (Renton/Everett).

Washington CPA — Frequently Asked Questions
Do I need a Washington-licensed CPA, or can an out-of-state CPA handle my WA tax and audit work?
