If you live or work in Seattle, you pay no state or local income tax on your wages, salary, Social Security, pension, or IRA withdrawals. Washington has never successfully imposed a personal income tax, and Seattle has not added one of its own. That does not make the city tax-free. The state tax picture in Seattle is built around a high sales tax, King County property tax, a couple of mandatory payroll deductions, and a handful of narrower taxes on capital gains, estates, business revenue, and vehicle registration. Here is what each one actually costs you.
No State Income Tax
You will not file a Washington state income tax return. Nothing is withheld from your paycheck for state income tax, and the state does not tax wages, self-employment earnings, Social Security benefits, pensions, or distributions from 401(k)s and IRAs. Federal income tax still applies the same way it does everywhere else.
The reason traces back to the state constitution, which treats income as property and requires taxes within a class of property to be uniform. In 1933, the Washington Supreme Court held in Culliton v. Chase that a graduated income tax violated that uniformity rule, and that ruling has blocked every serious income tax proposal since.1Washington State Legislature. Constitution of the State of Washington
Sales Tax You Pay Every Day
Washington leans hard on consumption taxes to replace the missing income tax. The state rate is 6.5%, and Seattle layers city, county, and transit district surcharges that push the combined rate to roughly 10.35%.2Washington State Legislature. RCW 82.08.020 – Tax Imposed, Retail Sales, Retail Car Rental The combined rate can shift slightly each quarter as local levies change, so check the Department of Revenue’s rate lookup tool before a large purchase.
You pay sales tax on clothing, electronics, furniture, restaurant meals, and many services such as construction and repair work. If you buy something online from a retailer that does not collect Washington tax, you technically owe an equivalent use tax on the purchase yourself.

Grocery food and food ingredients for home preparation are exempt, though prepared meals, soft drinks, bottled water, and dietary supplements are not.3Washington State Legislature. RCW 82.08.0293 Prescription drugs dispensed by a pharmacy are also exempt.4Washington State Legislature. RCW 82.08.0281
Property Tax if You Own a Home
Homeowners in Seattle pay annual property taxes to King County based on the assessed value of the property. The money funds state education, county services, city operations, and special districts. The rate per $1,000 of assessed value shifts each year with voter-approved levies and overall assessed values.
Payments split into two installments. The first half is due April 30, and the second half is due October 31.5King County. Property Tax Payment Information Missing a deadline triggers 1% monthly interest on the unpaid balance. A 3% penalty is added on June 1 for a late first-half payment, and an 8% penalty hits on December 1 for anything still outstanding.6King County. 2025 Property Taxes – King County, Washington These stack, so falling behind gets expensive quickly.
Senior, Disabled, and Veteran Exemption
King County reduces property tax for homeowners who are at least 61, disabled, or veterans with a service-connected disability, as long as total household income is $84,000 or less after qualified deductions.7King County. Senior Exemption Portal The home must be your primary residence, and you must have lived in it more than six months of the preceding year. Surviving spouses may qualify if the deceased partner had an exemption at death and the survivor was at least 57 that year. You can apply retroactively up to three years from the tax due date for a refund on amounts already paid.
Business Personal Property
If you run a business, you also owe personal property tax on equipment, furniture, computers, machinery, and signs used in operations. Business inventory and intangible property like trademarks are exempt.8Washington State Department of Revenue. Personal Property Tax You file a Personal Property Tax Listing Form with the King County Assessor by April 30 each year, reporting all taxable assets in the county as of January 1.
Capital Gains Tax on Large Investment Sales
Washington imposes a 7% tax on profits from selling long-term investments such as stocks, bonds, and business interests.9Washington State Legislature. RCW 82.87.040 – Tax Imposed, Long-Term Capital Assets It only applies after your net gains for the year exceed a $250,000 standard deduction, which the Department of Revenue adjusts upward each year for inflation.10Washington State Legislature. Washington Code 82.87 – Capital Gains Tax For most Seattle residents, it never comes up; the tax targets large, concentrated windfalls.
Real estate sales, retirement account distributions, and gains inside tax-deferred accounts are all excluded.10Washington State Legislature. Washington Code 82.87 – Capital Gains Tax Selling your Seattle home or cashing out a 401(k) does not trigger this tax.
Washington Estate Tax
Washington is one of roughly a dozen states with its own estate tax, and the threshold is much lower than the federal one. For 2026, estates valued above $3,076,000 must file a Washington estate tax return.11Washington Department of Revenue. Estate Tax The federal exemption sits around $13.99 million in 2025, so a Seattle homeowner with substantial real estate equity and retirement savings could owe state estate tax while owing no federal estate tax at all.
Rates are graduated from 10% on the first $1 million of taxable estate value up to 35% on amounts over $9 million.12Washington State Legislature. RCW 83.100.040 A qualified family-owned business deduction can reduce the taxable estate by up to $3,076,000 if the business meets specific ownership and activity requirements.11Washington Department of Revenue.

Payroll Deductions on Your Seattle Paycheck
Even without state income tax withholding, your paycheck will show two mandatory state deductions beyond federal taxes. Combined, they add about 1.4% on top of Social Security and Medicare, and they are easy to miss when budgeting take-home pay in a “no income tax” state.
- Paid Family and Medical Leave: Washington’s PFML program charges a total premium of 1.13% of gross wages up to the Social Security wage cap ($184,500 in 2026). Employees pay 71.43% of that premium and employers cover the rest. If your employer has fewer than 50 workers, the entire premium may come from your wages. In exchange, you can draw paid leave benefits for qualifying medical events, new children, or family caregiving.13Washington State’s Paid Family and Medical Leave. Estimate Your Paid Leave Payments
- WA Cares Fund: A long-term care program funded by a 0.58% payroll deduction on all wages with no cap. Benefits become available starting July 1, 2026, providing up to $36,500 in long-term care coverage that grows with inflation. Workers who secured a private long-term care policy and applied for an exemption before the original deadline are not subject to the deduction.14WA Cares Fund. How the Fund Works
Taxes if You Run a Business in Seattle
Washington’s main business tax is the Business and Occupation (B&O) tax, a gross receipts tax on total revenue regardless of profit.15Washington State Legislature. Washington Code 82.04 – Business and Occupation Tax Rates vary by activity, with retailing, manufacturing, and services each taxed differently and service businesses paying the highest rate. Freelancers and sole proprietors often get caught off guard: even if you barely break even, you owe B&O tax on every dollar of revenue.
Seattle imposes its own city B&O tax on top of the state version, which means businesses in city limits file with both the state Department of Revenue and the City of Seattle. Starting January 1, 2026, Seattle raised its city B&O threshold from $100,000 to $2 million in annual taxable revenue.16City of Seattle. Business Taxes If your business brings in less than $2 million, you likely owe no city B&O tax for that year. Businesses above that threshold also get a $2 million standard deduction, so the tax only applies to revenue above that amount. You still file an annual return and report gross revenue to the city even if you owe nothing.
JumpStart Payroll Expense Tax
Seattle’s JumpStart tax is a payroll expense tax paid by larger employers. For 2026, it targets businesses with more than roughly $9.07 million in total payroll expenses in the prior year and at least one employee earning $194,452 or more. The tax applies to each qualifying employee’s wages above that compensation threshold, at rates ranging from about 0.75% up to 2.56% depending on the company’s total payroll size and the employee’s pay level. The highest rate hits only companies with payroll exceeding $1.3 billion, and only on individual compensation above roughly $518,500. The employer pays this tax; it does not come out of your paycheck.
Vehicle Registration
Registering a car in Seattle costs more than in most of the state because Seattle sits inside the Sound Transit district. Vehicle owners pay a 1.1% Regional Transit Authority (RTA) motor vehicle excise tax on top of standard registration fees.17Washington State Department of Licensing. Regional Transit Authority (RTA) Tax The tax is calculated on a depreciated value tied to the vehicle’s original MSRP and a state depreciation schedule. On a newer car with a $40,000 MSRP, expect several hundred dollars annually just for this charge. The amount drops as the vehicle ages, but it is a noticeable line on your tab renewal that residents outside the transit district do not see.
