Washington State has no personal income tax due to a constitutional prohibition on graduated income taxes. However, it has a 7% capital gains excise tax on gains above $262,000, a state estate tax starting at $2.19M (much lower than federal), Seattle’s 10.25% sales tax, and a B&O gross receipts tax on businesses. High earners face a more complex picture than the ‘no income tax’ headline suggests.

Introduction
Washington State is often cited as a no-income-tax state, and for most wage earners that is accurate — there is no tax on wages, salaries, or investment income in Washington. However, Washington’s tax system is more complex for high earners and business owners than the headline suggests. The state introduced a 7% capital gains excise tax in 2022 (upheld by the Washington Supreme Court in 2023) that applies to long-term capital gains above $262,000. Washington also has one of the most aggressive state estate taxes in the nation, with a threshold of just $2.193M — dramatically lower than the $15M federal exemption — and progressive rates reaching 20%.
For businesses, Washington’s Business and Occupation (B&O) tax — a gross receipts tax with no deduction for costs — is a significant burden unique to Washington and a handful of other states. Seattle’s combined sales tax rate of 10.25% is among the highest in the country. This guide explains the full Washington State tax picture for 2026: what residents pay, what businesses pay, the capital gains tax mechanics, the estate tax threshold that catches many families by surprise, and how Washington compares to neighboring Oregon and Idaho.
Section 01
Washington’s Capital Gains Excise Tax: What High Earners Need to Know
Background: How Washington Created a Capital Gains Tax
Washington’s constitution has long been interpreted as prohibiting a graduated income tax — the state Supreme Court ruled in 1933 that income is property, and a graduated tax on property violates the constitutional requirement for uniform taxation. To work around this, the legislature passed a capital gains tax framed as an excise tax on the act of selling assets rather than a tax on income. After legal challenges, the Washington Supreme Court upheld the tax as an excise tax (not an income tax) in a landmark March 2023 ruling.
How the Capital Gains Excise Tax Works
The 7% tax applies to long-term capital gains above the annual threshold:
2024 threshold: $262,000 per individual (indexed for inflation)
Only long-term gains (assets held more than one year) are subject to the tax
The tax is 7% of the amount above the threshold — so $262,000 of gains are always tax-free
Exempt assets: real estate (residential and commercial), assets in retirement accounts (IRA, 401k, 403b, pension), interests in family-owned small businesses, agriculture assets

Who This Primarily Affects
The capital gains tax primarily affects tech workers exercising stock options, founders selling businesses (though small business interests may be exempt), investors selling large stock portfolios, and high earners realizing large investment gains in a single year. Real estate gains from selling property remain exempt, which protects most homeowners. Retirement account distributions are also exempt, protecting most retirees. The tax is highly concentrated — the vast majority of Washington residents will never trigger it.
Section 02
Washington’s Estate Tax: The $2.19M Threshold That Catches Families Off Guard
Washington State Estate Tax Overview
Washington State imposes its own estate tax on estates of Washington residents dying with assets above $2.193M (2024, indexed for inflation). This is dramatically lower than the federal estate tax threshold of $15M. Many families with a paid-off home plus retirement savings and life insurance can easily exceed $2.193M without being “wealthy” by national standards — particularly in Seattle and the Eastside where home values commonly exceed $1.5M–2M.

No Portability: A Critical Washington Distinction
Federal estate tax allows “portability” — a surviving spouse can inherit the deceased spouse’s unused federal exemption. Washington State does not allow portability of the WA estate tax exemption. Each individual has only their own $2.193M exemption. For a married couple, this means that if the first spouse to die leaves everything to the surviving spouse (which passes estate-tax-free due to the marital deduction), the surviving spouse will then have an estate totaling both spouses’ accumulated assets — subject to only one $2.193M exemption at death. Estate planning for Washington residents must address this with tools like a credit shelter trust (also called a bypass trust or AB trust) to use both spouses’ exemptions.

Section 03
Sales Tax, B&O Tax, and Washington’s Total Tax Picture
Washington Sales Tax
Washington’s 6.5% state sales tax is supplemented by significant local additions. The combined rates in major cities are among the highest in the country:
Seattle (King County): 10.25%
Bellevue: 10.2%
Tacoma (Pierce County): 10.2%
Spokane: 8.9%
Vancouver (Clark County): 8.5%
Groceries (unprepared food) are exempt from Washington sales tax. Prescription drugs are exempt. Restaurant meals and prepared food are fully taxable. Washington’s high sales tax falls more heavily on lower-income residents who spend a higher proportion of income on taxable goods — a regressive feature that critics argue is exacerbated by the absence of an income tax.
Business and Occupation (B&O) Tax
Washington’s B&O tax is a gross receipts tax on all business activity in the state — it applies to revenue, not profit. There is no deduction for wages, materials, rent, or other business costs. This makes it uniquely burdensome for low-margin businesses:
Retailing: 0.484% of gross sales
Services: 0.471% of gross revenue
Manufacturing: 0.484% of gross value of products
Wholesaling: 0.484% of gross proceeds
A service business with $2M in revenue and $1.8M in costs (90% margin consumed by expenses) owes B&O tax of $9,420 regardless of whether it made a profit. For profitable tech businesses common in the Seattle area, the B&O tax is relatively manageable. For businesses in thin-margin industries (staffing, distribution, retail), it can be a meaningful burden.
Washington’s Overall Tax Profile
Washington’s tax system is often described as regressive because lower- and middle-income residents pay no income tax but face high sales taxes and significant property taxes, while high earners benefit disproportionately from the income tax absence on wages. The capital gains tax and estate tax were both designed to add progressivity at the top. For high earners:

Washington State has no personal income tax on wages, salaries, retirement income, dividends, or interest. The state constitution has been interpreted to prohibit a graduated income tax. This benefits most residents — particularly wage earners — who pay no state income tax at all. However, Washington does have a capital gains excise tax (7% on long-term gains above $262,000), a B&O tax on businesses, a state estate tax starting at $2.193M, and high sales taxes (10.25% in Seattle). The ‘no income tax’ story is accurate but incomplete for high earners and business owners.
Q
What is Washington State’s capital gains tax and who pays it?
Washington’s capital gains excise tax is a 7% tax on long-term capital gains (assets held over one year) that exceed $262,000 per individual (2024 threshold, indexed for inflation). Gains below the threshold are not taxed. Key exemptions: real estate sales are fully exempt, retirement account assets are exempt, family-owned small business interests may be exempt, and agricultural assets are exempt. The tax primarily affects tech employees exercising stock options, investors with large stock portfolio sales, and founders selling businesses. The tax was upheld by the Washington Supreme Court in March 2023.
Q
Why does Washington State have such a low estate tax threshold?
Washington State’s estate tax has a $2.193M threshold because it was originally tied to the federal estate tax system as it existed in 2005, before the federal threshold was raised dramatically. When Congress decoupled state and federal estate taxes, Washington chose to keep its lower threshold. The state legislature has raised it modestly over the years but has not brought it in line with the federal $15M exemption. In the Seattle metro, where home values routinely exceed $1.5M, a family with a $1.8M home plus $600,000 in retirement savings and life insurance can easily exceed $2.193M — making estate planning critical for Washington residents.
Q
What is the B&O tax in Washington and do I have to pay it?
Washington’s Business and Occupation (B&O) tax is a gross receipts tax that applies to businesses operating in Washington. It is taxed on total revenue — not profit — at rates ranging from 0.484% (retail, manufacturing) to 0.471% (services). Most businesses with nexus in Washington owe B&O tax. There is a small business credit/exemption for businesses with very low gross income (under approximately $125,000 in some categories), but most active businesses will owe B&O. As a freelancer or sole proprietor operating in Washington, you also owe B&O on your gross revenue. This tax is unique to Washington (and a handful of other states) and is in addition to, not instead of, federal business taxes.
Q
How do property taxes work in Washington State?
Washington State property taxes are levied at the county level and typically run around 0.94% effective rate statewide. In King County (Seattle/Bellevue), effective rates are approximately 0.87%, though the high property values mean dollar amounts are substantial. A $1M home in Seattle carries an annual property tax bill of approximately $8,700–$10,000. Washington has a partial property tax exemption program for senior citizens and disabled persons meeting income requirements. There is no homestead exemption comparable to Florida’s. Property taxes are the primary revenue source for Washington schools and local services in the absence of an income tax.
Q
Is Washington State a good place for retirees from a tax perspective?
Washington State has a mixed retirement tax profile. On the positive side: no income tax means pension income, IRA distributions, 401(k) withdrawals, Social Security, and dividend income are all completely free from state income tax. On the negative side: the estate tax starting at $2.193M is a significant concern for property-rich retirees in the Seattle area; sales taxes at 10.25% in Seattle are very high; and property taxes on high-value homes are substantial. Retirees drawing income from retirement accounts and living modestly may find Washington attractive. Retirees with significant estates or high investment income realizing capital gains above $262,000 face meaningful state-level tax exposure.
Q
How does Washington compare to Oregon for taxes?
Washington and Oregon take very different approaches. Washington has no income tax but high sales tax (10.25% Seattle) and an estate tax from $2.193M. Oregon has a high income tax (up to 9.9%, and a new 1% Metro tax in Portland), no sales tax at all, and an estate tax from $1M. For high earners: Washington is generally better on income (no income tax) but Oregon’s estate tax threshold of $1M is even lower. For retirees with large estates, neither state is ideal — but Washington’s higher estate threshold and no income tax on retirement distributions makes it preferable to Oregon for most retirees. For expats and those with complex foreign income: Washington’s no-income-tax status means only federal and foreign reporting applies at the state level.
