Washington Tax Overview โ What Workers Need to Know
Washington State levies zero personal income tax on wages, salaries, and self-employment earnings, making it one of the most attractive states for high-income tech workers โ particularly those employed by Amazon, Microsoft, Boeing, and the growing Puget Sound startup ecosystem. However, Washington is not entirely tax-free: voters approved a 7% capital gains tax in 2021 on the sale of stocks, bonds, and other capital assets exceeding $250,000 per year (upheld by the Washington Supreme Court in 2023), and the state has one of the highest sales tax rates in the nation at 6.5% state + up to 4% local additions (10.25% in Seattle). Washington funds its government through sales taxes (the largest revenue source), a Business and Occupation (B&O) tax on gross receipts, property taxes, and the new capital gains tax. For W-2 employees, the absence of state income tax is a significant advantage: a software engineer earning $180,000 at Amazon in Seattle keeps approximately $9,000โ$12,600 more per year compared to a similar role in California (where the effective state tax rate at that income is roughly 7%). Washington's median household income of $90,325 is the 4th highest nationally, driven largely by the tech industry. The state's cost of living index is 110.7, or about 10.7% above the national average, with housing in the Seattle metro area being the primary cost driver.
