Seattle does not have an income tax, and Washington state does not have one either. Your wages, salary, tips, and other earned income are not subject to any state or city income tax withholding, and you will never file a state or local income tax return. That said, living in Seattle is not tax-free. Washington makes up the revenue through one of the highest sales tax rates in the country, property taxes, a capital gains tax on large investment sales, and mandatory payroll premiums that show up on your pay stub.
No Income Tax at the State or City Level
Washington has no individual or corporate income tax.1Washington Department of Revenue. Income Tax Whether you earn $30,000 or $3 million, no percentage of your paycheck is withheld for state or city income tax. No Washington employer withholds it because there is nothing to withhold.
State law also blocks Seattle from creating its own income tax. Under RCW 36.65.030, no county, city, or combined city-county in Washington may levy a tax on net income.2Washington State Legislature. Revised Code of Washington 36-65-030 – Tax on Net Income Prohibited Even if the Seattle City Council voted to impose one, the statute would preempt it.
Why the Rule Is So Hard to Change
The absence of an income tax is anchored in the state constitution. Article VII, Section 1 requires that all taxes be uniform upon the same class of property.3FindLaw. Washington Constitution Art 7 1 – Taxation In 1933, the Washington Supreme Court held in Culliton v. Chase that income is a form of property, which killed a voter-approved graduated income tax. Because income counts as property, any tax on it must be uniform, so the state cannot legally charge higher earners a higher rate.
A second provision makes even a flat income tax impractical. Article VII, Section 2 caps combined property tax levies at one percent of true and fair value.4Washington State Legislature. Amendment 95 (2002) – Art 7 Section 2 Limitation on Levies Applied to income, that cap would limit any tax to one percent, which is too low to be a meaningful revenue source. Changing this would require a constitutional amendment, and voters have rejected that path multiple times.
What Actually Comes Out of Your Paycheck
Two mandatory state programs show up as deductions on your pay stub. They are technically insurance premiums, not income taxes, but they reduce your take-home pay the same way.
Paid Family and Medical Leave
Washington’s Paid Family and Medical Leave program provides paid time off for qualifying medical events, bonding with a new child, or certain military-connected situations. For 2026, the total premium is 1.13% of your gross wages, up to the Social Security wage cap of $184,500.5Washington State’s Paid Family and Medical Leave. Updates If your employer has 50 or more employees, the cost splits between you and your employer: you pay 71.43% of the premium and your employer covers the rest. At smaller companies you may pay the full amount yourself, because employers with fewer than 50 workers are not required to contribute.6Washington State’s Paid Family and Medical Leave.

WA Cares Fund
The WA Cares Fund is a state-run long-term care insurance program. The 2026 premium rate is 0.58% of your gross wages with no earnings cap, paid entirely by the employee.7Employment Security Department / Paid Leave WA. Employer Wage Reporting and Premiums Toolkit Some workers are exempt. Holders of a non-immigrant work visa are automatically exempt starting January 1, 2026, and workers who obtained the private insurance opt-out before the December 31, 2022 deadline keep that exemption.8WA Cares Fund. Exemptions Veterans with a service-connected disability rating of 70% or higher, active-duty military spouses, and workers who live outside Washington may also qualify.
Together the two premiums come to roughly 1.4% to 1.71% of your gross wages depending on your employer’s size.
What You Pay Instead: Sales and Property Tax
Washington relies heavily on consumption taxes to replace the revenue an income tax would produce. The combined sales tax rate in Seattle is currently 10.55%, made up of the 6.5% state rate plus local levies for the city, King County, and the Regional Transit Authority. That puts Seattle among the highest-tax cities in the country at the register. Groceries for home consumption, prescription drugs, and insulin are exempt.
Property taxes are the other major source. Your bill is calculated as a dollar amount per $1,000 of assessed value, and the rate depends on which taxing districts your property sits in. The aggregate of regular property tax levies statewide is constitutionally capped at one percent of true and fair market value, though voter-approved special levies for schools and other purposes can push your effective rate higher.4Washington State Legislature. Amendment 95 (2002) – Art 7 Section 2 Limitation on Levies
Two targeted excise taxes hit Seattle residents in particular. Distributors pay $0.0175 per fluid ounce on sugary drinks sold in the city, a cost typically built into shelf prices.9City of Seattle. Sweetened Beverage Tax Vehicle owners inside the Sound Transit district pay an annual Regional Transit Authority excise tax of 1.1% of their vehicle’s depreciated value at tab renewal.10Washington State Department of Licensing. Regional Transit Authority (RTA) Tax
Add these together and your overall tax burden as a Seattle resident is not necessarily lower than in an income-tax state. The burden is structured differently, falling on spending and property rather than earnings.
Capital Gains Tax on Large Investment Sales
Washington imposes an excise tax on the sale or exchange of long-term capital assets, mainly stocks, bonds, and business interests held for more than one year. The base rate is 7% of your Washington capital gains above a standard deduction. Starting in 2025, an additional 2.9% applies to the portion of gains above $1 million, bringing the combined rate to 9.9% on gains over that threshold.11Washington State Legislature. RCW 82.87.040 – Tax Imposed – Long-Term Capital Assets
The standard deduction is inflation-adjusted each year. For 2025 it was $278,000, whether you file individually or jointly with a spouse.12Washington Department of Revenue. Capital Gains Tax You owe tax only on gains above the deduction, not on the full sale amount.
Several categories are entirely exempt:
- All real property transferred by deed, contract, or judgment.
- Distributions from 401(k) plans, 403(b) accounts, IRAs, and similar retirement accounts.
- The portion of a gain from selling an interest in a privately held entity that is directly attributable to real estate the entity owns.13Washington State Legislature. Chapter 82.87 RCW – Capital Gains Tax
The tax survived a constitutional challenge in 2023, when the Washington Supreme Court held in Quinn v. State that it is an excise tax on the transaction rather than a property tax on the asset.14Washington State Courts. Quinn v State, No 100769-8 Filing is due on the same date as your federal return, typically April 15. Late filings incur a penalty of 5% of the tax owed for each month or partial month the return is unfiled, up to 25%.13Washington State Legislature. Chapter 82.87 RCW – Capital Gains Tax
The State Estate Tax Catches Smaller Estates
No income tax does not mean no wealth tax at death. Washington is one of roughly a dozen states with its own estate tax. For 2026, estates valued at $3,076,000 or less are exempt, and amounts above that threshold owe Washington estate tax at graduated rates.15Washington Department of Revenue. Estate Tax Tables That figure is well below the current federal exemption, so a Seattle estate can owe state tax even when no federal estate tax is due.
If You Freelance or Run a Small Business
Self-employment income is not free of state tax. Washington imposes a Business and Occupation (B&O) tax on gross receipts, meaning you owe on total revenue, not profit. The filing threshold is $125,000 in annual gross income; below that you do not need to file. A small-business credit reduces the effective tax for businesses earning under $250,000.1Washington Department of Revenue. Income Tax
Seattle also requires most businesses operating in the city to hold a business license tax certificate. The annual fee for 2026 is tiered by prior-year taxable revenue:
- Less than $20,000: $73
- $20,000 to $499,999: $147
- $500,000 to $1,999,999: $667
- $2 million to $5 million: $1,604
- More than $5 million: $3,21016City Finance | seattle.gov. Business Licenses
Businesses with $4,000 or less in annual Seattle revenue and no physical location in the city are exempt from the license requirement. New applicants pay the lowest tier fee in their first year.
One boundary worth naming: Seattle also imposes a JumpStart payroll expense tax on large employers with high-earning staff. It is a tax on the employer, not on you, and state law prohibits your employer from passing the cost to you through payroll deductions.17City Finance | seattle.gov. Payroll Expense Tax
The Federal SALT Deduction Angle
Because Washington has no income tax, Seattle residents who itemize on their federal return can deduct state and local sales taxes instead. The IRS lets you choose between deducting state income taxes or state sales taxes on Schedule A, not both, so the sales tax election is the only meaningful option here.18Internal Revenue Service. Publication 17 (2025), Your Federal Income Tax Given Seattle’s high combined sales tax, this can add up.
The total state and local tax deduction, covering sales tax plus property taxes together, is capped at $40,000 for 2025 returns ($20,000 if married filing separately), with the cap rising 1% annually through 2029.18Internal Revenue Service. Publication 17 (2025), Your Federal Income Tax For filers with adjusted gross income above $500,000, the cap phases down to $10,000. You can calculate your sales tax deduction from actual receipts or use the IRS sales tax tables, which estimate the deduction based on your income and location.
