No, Seattle is not tax free. Washington charges no state income tax on your wages, salary, or retirement withdrawals, which is where the “tax free” reputation comes from, but the state and city make up for it with a sales tax above 10 percent, a capital gains excise tax, property taxes, a real estate excise tax when you sell a home, and one of the lowest estate tax exemptions in the country. Federal income tax applies to Seattle earners the same as anywhere else.
What Seattle and Washington Don’t Tax
Washington imposes no personal or corporate income tax at the state level, and no city or county in the state can add one.1Washington Department of Revenue. Income Tax That covers wages, salaries, self-employment earnings, pensions, Social Security, and distributions from retirement accounts. A Seattle worker making $100,000 keeps more of each paycheck than a counterpart in Portland or San Francisco.
Federal income tax still applies in full. And the absence of a state income tax does not mean the absence of state revenue collection; Washington simply raises its money through consumption and transaction taxes instead.
Sales Tax: The Tax You’ll Feel Every Day
The combined state and local sales tax in Seattle is 10.25 percent, built from a 6.5 percent state rate plus local components funding transit, criminal justice, and other services.2Washington Department of Revenue. Retail Sales Tax You pay it on most retail purchases: clothing, electronics, furniture, restaurant meals, and many repair or installation services on tangible goods.
Grocery staples are exempt. Food and food ingredients sold for home consumption are not taxed.3Washington State Legislature. Washington Code 82.08.0293 – Exemptions, Sales of Food and Food Ingredients Prepared food, soft drinks, bottled water, and dietary supplements are taxable. Prescription drugs and most prescribed medical devices, including prosthetics and kidney dialysis equipment, are also exempt.4Legal Information Institute. Washington Administrative Code 458-20-18801 – Medical Substances, Devices, and Supplies for Humans
Buying Across the Oregon Border Doesn’t Work
Oregon charges no sales tax, which tempts Seattle residents to drive south for big purchases. Washington closes the loophole with a use tax: if you buy something out of state without paying sales tax, you owe the difference when you bring it into Washington. This applies to vehicles, furniture, appliances, and virtually any tangible good.
Cars get the closest scrutiny. Buy a vehicle in Oregon and register it in Washington, and the state collects use tax at your local rate when you title it. New residents who owned a vehicle for more than 90 days before moving to Washington can qualify for an exemption, as long as they register within 30 days of the move.5Washington Department of Revenue. Vehicles Brought Into Washington From Out-of-State A car bought fewer than 90 days before the move does not qualify.
Property Tax if You Own a Home
Seattle homeowners pay annual property taxes based on the assessed value set each year by the King County Assessor. Rates vary by taxing district, but a typical combined rate runs roughly $9 to $13 per $1,000 of assessed value. On an $800,000 home, that is an annual bill of about $7,200 to $10,400, depending on location and approved levies.
Payment is split in two: the first half is due April 30, the second half October 31. If either date falls on a weekend or county holiday, the deadline moves to the next business day.6King County, Washington. Frequently Asked Questions (FAQ) Unpaid property taxes accrue interest at a rate set annually by the county, and continued nonpayment can lead to a tax lien.
Homeowners who are 61 or older, or disabled, may qualify for a property tax reduction. For a reduction on 2026 property taxes, household income after qualified expense deductions must be $84,000 or less, and household income includes earnings from you, your spouse or domestic partner, and any co-owner living with you.7King County. Property Tax Exemptions for Seniors and Persons With Disabilities Depending on income level, the exemption can reduce assessed value, freeze values, or eliminate certain excess levies.
Capital Gains Tax on Investment Profits
Washington imposes an excise tax on profits from selling long-term capital assets such as stocks, bonds, and business interests held longer than one year. The Washington Supreme Court upheld the tax as an excise on the transaction rather than a tax on income. Two tiers apply as of 2025:
- 7 percent on taxable Washington capital gains up to $1,000,000
- 9.9 percent (7 percent plus an additional 2.9 percent) on the portion above $1,000,0008Washington State Legislature. Washington Code 82.87.040 – Tax Imposed, Long-Term Capital Assets
A standard deduction protects most sellers. For 2025 it was $278,000, and it adjusts annually for inflation.9Washington Department of Revenue. Capital Gains Tax The deduction applies per individual, or per married couple filing jointly, and is not doubled for joint filers.
Several categories of gains are excluded entirely. Real estate sales are not covered; they fall under the separate real estate excise tax below. Gains inside retirement accounts such as 401(k)s and IRAs are excluded. Selling all or substantially all of a qualified family-owned small business may qualify for a full deduction if the business had worldwide gross revenue under roughly $11.1 million in the prior year.
Your Washington capital gains return is due the same date as your federal return, typically April 15. You can extend the filing deadline, but not the payment deadline. Late filing without an extension triggers a penalty of 5 percent of the tax due per month, capped at 25 percent, with additional interest and penalties on late payments.10Washington State Legislature. Washington Code Chapter 82.87 – Capital Gains Tax
Residency matters here. Non-residents generally owe the tax only on gains tied to Washington-based assets, but Washington presumes you are a resident if you are a registered voter in the state, receive state public assistance, or obtained a Washington driver’s license claiming residency.11Washington State Legislature. Washington Administrative Code 308-99-020 – Definitions Even without any single factor, a combination of two or more indicators can trigger a residency presumption. If you split time between states, review the factors before assuming you owe nothing.
Real Estate Excise Tax When You Sell
Selling a home in Seattle triggers a real estate excise tax (REET) from both the state and the city, calculated on the sale price. The state portion uses graduated tiers; through 2025 those were:
- 1.10 percent on the portion up to $525,000
- 1.28 percent on $525,001 to $1,525,000
- 2.75 percent on $1,525,001 to $3,025,000
- 3.00 percent on anything above $3,025,00012Washington Department of Revenue. Real Estate Excise Tax
Seattle adds a local REET of 0.50 percent on top of the state rate.13Washington Department of Revenue. Local Real Estate Excise Tax Rates On a $900,000 Seattle home sale, the combined REET easily exceeds $14,000, a cost worth building into closing calculations.
Washington Estate Tax
Washington is one of the few states with its own estate tax, separate from the federal estate tax. For deaths occurring in 2026, estates valued above $3,076,000 must file a Washington estate tax return, and only the portion above that exclusion is taxed.14Washington Department of Revenue. Estate Tax Graduated rates begin at 10 percent on the first $1,000,000 of taxable estate and climb to 35 percent on anything above $9,000,000.15Washington Department of Revenue. Estate Tax Tables
The federal exclusion for 2026 is far higher, around $7 million per person under the scheduled sunset of the 2017 tax law. Many estates that owe nothing federally will still owe Washington estate tax. For Seattle homeowners whose property values push their total estate above $3,076,000, this is a significant planning consideration.
If You Own a Business in Seattle
Business taxes in Washington do not work on net profit. The state’s Business and Occupation (B&O) tax applies to gross receipts with no deductions for labor, materials, or other costs, so you owe it even in a losing year.16Washington Department of Revenue. Business and Occupation Tax Rates vary by classification. For service businesses, the rate ranges from 1.5 percent to 2.1 percent depending on prior-year revenue; retailers and manufacturers generally pay lower rates.17Washington Department of Revenue. Business and Occupation Tax Classifications Low-margin businesses like grocery stores or construction firms feel this structure most.
Seattle layers its own B&O tax on top. Effective January 1, 2026, the city threshold rose from $100,000 to $2,000,000 in annual taxable gross revenue, meaning most smaller businesses will not owe city B&O.18City Finance. Business Taxes For those above the threshold, city rates are 0.342 percent on retail and manufacturing and 0.658 percent on service and other activities.19City Finance. Tax Rates and Classifications
Large employers also face the JumpStart Seattle payroll expense tax. For 2026 it applies to businesses with at least $9,074,409 in total Seattle payroll during 2025 that pay at least one employee $194,452 or more.20City Finance. Payroll Expense Tax Rates are progressive, rising with total payroll and individual compensation levels.
Missed B&O or use tax payments escalate fast. A 9 percent penalty hits immediately, rises to 19 percent at the end of the following month, and reaches 29 percent after two months, with interest tied to the federal short-term rate plus two percentage points layered on top.21Legal Information Institute. Washington Administrative Code 458-20-228 – Returns, Payments, Penalties, Extensions, Interest, Stays of Collection Intentional failure to report can trigger a 50 percent evasion penalty.
