Washington Income Tax 2026

Washington does not levy a state income tax on wages in 2026. Your paycheck is reduced only by federal income tax, Social Security and Medicare - so you keep more than in most states. Washington imposes NO individual income tax on wages or salaries for tax year 2026 - one of nine states without a broad personal income tax. No standard deduction or personal exemption exists because there is no wage income tax. No local or city income taxes on wages. Retirement income and Social Security are not taxed (no income tax exists). State revenue relies on sales/use tax and the B&O (business and occupation) gross-receipts tax. Separately, Washington levies a 7% excise tax on long-term capital gains above an inflation-indexed annual threshold (about $262,000 for 2025/2026), with a 9.9% rate tier on gains above $1M; this is a capital gains excise tax and does NOT apply to wage/salary income. Note: the 2026 legislature adopted a 9.9% 'millionaires' tax' on individual income over $1M, but it does NOT take effect until January 1, 2028 (first returns 2029) and is expected to face legal challenges - it has no effect on 2026 wage taxation.
