Washington State: No Personal Income Tax
Washington state levies no personal income tax on wages, salaries, or bonuses, making it one of the most tax-advantaged states for salaried tech workers in the country. Home to Amazon, Microsoft, Boeing, and a dense cluster of tech companies in the Seattle/Bellevue metro, Washington is one of the most important states for US tech compensation.
Washington has no personal income tax. $0 in state income taxes on wages and RSU income. Federal income tax still applies to all income — "no state income tax" refers to state-level taxation only.
On a $150,000 salary, a Washington state resident pays $0 in state income tax. The same gross salary in California would generate roughly $11,000 to $13,000 in state income taxes annually. For senior engineers and managers at Seattle-area companies with large RSU grants, the tax advantage compounds significantly. A $500,000 RSU vesting event that would trigger $66,500 in California state tax (at the 13.3% top marginal rate) generates $0 in Washington state income tax.
Washington does impose a capital gains tax of 7% on long-term capital gains above $250,000 per year (effective 2023), after years of litigation. This affects a small minority of employees, primarily those selling large blocks of company stock, but is worth noting for senior tech employees with substantial equity. Wages, RSU income at vesting, and bonuses are not subject to this capital gains tax.
Washington also collects a 6.5% state sales tax and a Business & Occupation (B&O) tax on businesses, and property taxes apply. For W-2 salaried employees without large capital gains, the effective state tax burden in Washington is among the lowest in the country for high earners.
Using Washington's tax advantage in negotiations
Seattle-area compensation packages are often structured with large equity grants. The no-income-tax environment means RSU vesting events that trigger large tax bills in California generate no state tax in Washington. When comparing a Seattle offer versus a San Francisco offer, the difference in state tax on RSU income alone can be decisive. The Compare Job Offers tool below models COL-adjusted salary comparisons. Combine that with the tax difference when evaluating equity-heavy packages.

Total Comp CalculatorFrequently asked questions: Washington income tax
Does Washington state have an income tax?
Washington state has no personal income tax on wages, salaries, bonuses, or RSU income. A 7% capital gains tax on gains above $250,000/year was upheld by the state Supreme Court in 2023, but this applies only to investment gains, not employment income.
How does Washington's tax environment compare to California for tech workers?
For salaried tech workers, Washington is significantly more tax-advantaged. California's top marginal rate is 13.3%. A Seattle-based engineer earning $200,000 in base salary saves roughly $16,000 to $22,000 per year in state income taxes versus a comparable California role. The advantage is even larger on RSU vesting events.
Does the Washington capital gains tax apply to RSU income?
No. RSU income at vesting is treated as ordinary wage income, not capital gains, under federal tax rules. Washington's capital gains tax applies only to long-term capital gains (e.g. profits from selling stock or real estate held over a year) above $250,000 per year. Most employees are not affected.
