Washington Capital Gains Tax 2026: 7% on Gains, 9.9% Over $1 Million

Washington State imposes a 7% tax on long-term capital gains (from assets held over one year) above an annual standard deduction ($278,000 for 2025; the 2026 amount had not been published at last check), with a 9.9% rate on taxable gains above $1 million from tax year 2025. Example: If you realize $400,000 in long-term capital gains, Washington taxes only the $122,000 above the standard deduction: $122,000 × 7% = $8,540 tax. The Department of Revenue received 4,461 capital gains tax returns for tax year 2024. Washington has no income tax on wages, salaries, pensions, or Social Security, making it one of nine no-income-tax states despite the capital gains tax.

Washington exempts several types of capital gains: (1) All real estate including primary homes, second homes, vacation properties, rental real estate, and commercial property; (2) Retirement accounts: gains within 401(k), IRA, pension plans, and other qualified accounts are exempt; (3) Qualified family-owned small business: gains from selling all or substantially all of a small family-owned business (worldwide gross revenue of $10 million or less, adjusted annually, plus other tests) can be deducted; (4) Depreciable business assets, timber, certain livestock, commercial fishing privileges, and goodwill from franchised auto dealership sales. These exemptions mean most Washington residents never pay the tax. Real estate investors, retirement savers, and small business owners are largely protected.

Strategies to minimize Washington capital gains tax: (1) Spread gains over multiple years: Use installment sales or structured sales to keep annual gains under $278,000 threshold; (2) Harvest capital losses: Offset gains with losses to stay under threshold; (3) Time sales strategically: If moving out of Washington or retiring, time large gains for after establishing residency elsewhere; (4) Invest in real estate: All real estate gains are exempt from Washington capital gains tax; (5) Maximize retirement accounts: Gains in 401(k)/IRA are exempt—contribute maximum and hold growth stocks in retirement accounts; (6) Qualified family-owned small business deduction: Structure ownership and revenue to meet the requirements; (7) Defer recognition: Use 1031 exchanges (real estate), qualified opportunity zones, or other deferral strategies. Consult a Washington CPA before large transactions.

No, Washington has no state income tax on wages, salaries, self-employment income, pensions, Social Security benefits, interest, or dividends. Washington is one of nine states with zero state income tax (along with Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, and Wyoming). However, Washington has had a 7% capital gains tax since 2022 on long-term capital gains above an annual standard deduction ($278,000 for 2025), with a 9.9% rate above $1 million of taxable gains from tax year 2025. It affects only a small share of residents. For the vast majority of Washington residents, there is no state tax on their income, making Washington highly tax-competitive especially for high earners who don't regularly realize large capital gains.

Washington and Oregon have fundamentally different tax structures: Washington: No income tax, 7% capital gains tax on gains above the standard deduction (9.9% above $1 million), 0.75% property tax, 6.5% state sales tax plus local rates. Oregon: 9.9% top income tax rate (progressive 4.75-9.9%), no separate capital gains tax (taxed as income at 9.9%), 0.81% property tax, 0% sales tax. For a high earner making $300,000/year with $100,000 capital gains: Washington pays $0 state tax (gains under the standard deduction); Oregon pays about $37,555 on $400,000 of combined income (single filer, 2026). Washington advantage: about $37,555/year. For a middle-income earner ($80,000/year, moderate spending): Washington pays an illustrative ~$2,500 in sales tax; Oregon income tax is about $5,398 for a single filer. Washington advantage: about $2,900/year. Washington is more tax-friendly for high earners and moderate earners, while Oregon's lack of sales tax helps low-income residents who spend most of their income.

The Washington Department of Revenue received 4,461 capital gains tax returns for tax year 2024 (and granted 3,403 extensions). Taxpayers can include: (1) Tech workers exercising large stock option grants ($500K+); (2) Investors selling concentrated stock positions; (3) Business owners selling businesses (if not qualifying for small business exemption); (4) High-net-worth individuals liquidating investment portfolios; (5) Trust fund beneficiaries receiving large capital gains distributions. Net payments for tax year 2024 were $560.6 million, roughly $125,000 per return filed. The vast majority of Washington residents never trigger this tax because they don't realize more than the standard deduction in annual capital gains, their gains are from exempt sources (real estate, retirement accounts), or they structure transactions to stay under the threshold.

Yes, as of March 2023, the Washington Supreme Court upheld the capital gains tax as constitutional. The court ruled 7-2 that the tax is an excise tax on the sale of certain assets, not an income tax. This distinction matters because Washington's constitution prohibits income taxes without voter approval and requires tax uniformity. The court found: (1) The tax is on the transaction/privilege of selling assets, not on income itself; (2) Graduated rates (0% under threshold, 7% above) are permissible for excise taxes; (3) The tax does not violate state constitutional provisions. While opponents continue to seek ballot initiatives to repeal the tax, it is currently legal, in effect, and being enforced. Future voter initiatives could potentially repeal it, but the constitutional challenge has been resolved in the state's favor.

Washington property taxes are moderate, averaging 0.75% of home value (22nd lowest nationally). This is: Lower than most high-income-tax states (Illinois 1.88%, New Jersey 1.88%, Connecticut 1.54%); Lower than Texas (1.40%, which has no income tax like WA); Slightly lower than Oregon (0.81%); Much higher than Hawaii (0.31%) or Alabama (0.42%). For a $500,000 home in Washington, average property tax is $3,750/year. In King County (Seattle), effective rates are 0.90-1.10%, so property tax on a $500,000 home is $4,500-$5,500/year. Seniors 61+ and disabled persons may qualify for property tax exemptions based on county income limits. Overall, Washington property taxes are reasonable compared to peer states and lower than many high-tax states.

Washington's state sales tax rate is 6.5%, and local jurisdictions add their own rates, so combined rates vary by location (see the Department of Revenue's local rate table). However, groceries (unprepared food) and prescription drugs are exempt. For a household spending $3,000/month on taxable purchases at an illustrative 9% combined rate, annual sales tax burden is approximately $3,240. Washington's high sales tax helps fund state services in the absence of income tax. Combined with no income tax and moderate property tax, Washington's overall tax burden is still lower than high-income-tax states for most residents.
