CPA Services in Washington
Washington State has no individual income tax, making it one of the most attractive states for high-income earners. The state funds its government through a combination of business and occupation tax (B&O tax), sales tax, and property taxes. Seattle’s status as a global technology hub — home to Amazon, Microsoft, and Boeing — creates significant demand for specialized CPA services around equity compensation, startups, and technology company taxation.
The B&O tax applies to gross receipts with no deduction for expenses or cost of goods sold, which creates unique planning challenges and opportunities. Washington CPAs are expert in this system, along with the state’s sales tax rules, and the complex equity compensation issues faced by thousands of tech workers in the Puget Sound region.

Washington CPA & Tax FAQ
Q: Does Washington State have an income tax?
Washington State has no individual income tax and no corporate income tax, making it one of the most tax-friendly states for individuals and traditional businesses. The state funds its government primarily through the business and occupation tax (B&O tax), sales tax, and property taxes. High-income investors should note that Washington passed a capital gains tax of 7% on gains over $250,000 (excluding real estate).
Q: What is Washington’s Business and Occupation Tax?
Washington’s B&O tax is a gross receipts tax on virtually all business activity. Unlike an income tax, there are no deductions for business expenses or cost of goods sold — the tax applies to total gross receipts. Rates vary by business classification: retailing (0.471%), service businesses (1.5%), manufacturing (0.484%), wholesaling (0.484%), and others. Businesses must track gross receipts by classification.
Q: How does Washington State sales tax work?
Washington has a 6.5% state sales tax with county and city taxes that bring the combined rate to 7.5%–10.5% depending on location (Seattle is 10.25%). Washington taxes most goods and some services, with various exemptions for food, prescription drugs, and certain manufacturing and agricultural inputs.
Q: What should tech employees in Washington know about the capital gains tax?
Washington passed a 7% excise tax on capital gains over $250,000 per year, beginning with 2022 gains. This applies to gains from stocks, bonds, and other capital assets (real estate excluded). For tech employees with significant stock option income or selling appreciated company stock, this can represent a significant new tax burden. The tax was upheld by the Washington Supreme Court in 2023.
Q: How does Seattle’s payroll expense tax affect businesses?
Seattle’s Jumpstart Payroll Tax applies to businesses with at least $8.135 million in annual Seattle payroll. The tax rate ranges from 0.7% to 2.4% of Seattle wages for employees earning over $182,500. For large employers in Seattle — particularly technology companies — this tax can be significant and is an employer obligation.
