Washington levies no personal income tax, and the tax that matters most to a business here works in a way that surprises people arriving from elsewhere.
The main business tax is charged on what you take in rather than on what you make, so a business with a loss can still owe it, and deduction planning does very little for it. There is also a capital gains charge and an estate tax to consider.
This covers what applies to individuals, how the business tax works and who it reaches, the sales and property position, and how planning here differs from a state that taxes income.
Washington State: No Individual Income Tax
Washington State does not impose a personal income tax on wages, salaries, or most other income. This is protected by the Washington State Constitution, which requires uniform taxation and has historically been interpreted to prohibit a graduated income tax.
The main business tax here is charged on what you take in rather than on what you make, so a business with a loss can still owe it. That is the opposite of how a profits tax behaves, and it makes deduction planning largely beside the point for it.

Washington residents pay federal income taxes at standard federal rates. No state income tax exemption affects federal obligations.

Washington's Capital Gains Tax: 7% (Post-2023)
Washington enacted a 7% capital gains tax on long-term capital gains exceeding $250,000 per individual per year, effective for gains realized on or after January 1, 2022.
- Upheld by the Washington State Supreme Court in March 2023
- Applies to: gains on stocks, bonds, business interests, and other capital assets
- Exempt: real estate, retirement accounts, farms, timberland
- First $250,000 of gains per year: exempt
- Revenue goes to the Education Legacy Trust Fund
Washington Business & Occupation (B&O) Tax
Washington does not have a corporate income tax. Instead, businesses pay the Business & Occupation (B&O) Tax on gross receipts:
| Business Category | B&O Rate |
|---|---|
| Retailing | 0.471% |
| Wholesaling | 0.484% |
| Manufacturing | 0.484% |
| Services (most) | 1.5% |
| Software development (royalties) | 1.5% |
| Travel agents | 0.275% |
B&O tax applies to gross income, no deduction for cost of goods sold or business expenses. This can be significant for low-margin businesses.
Washington Sales Tax
State sales tax: 6.5%. Local jurisdictions add their own rates, resulting in totals up to 10.4% in some areas (such as parts of King County / Seattle area).
Washington Estate Tax
Washington imposes a state estate tax on estates above a threshold:
| Taxable Estate | Rate |
|---|---|
| Over $2.193 million threshold | Graduated rates from 10% to 20% |
| Exemption | Approximately $2.193 million (2025, inflation-adjusted annually) |
| Marital deduction | Unlimited; deferred until surviving spouse's death |
Pro Tip: Washington's estate tax exemption ($2.193M) is much lower than the federal exemption ($13.61M). Many Washington residents owe Washington estate tax but not federal estate tax. Plan accordingly.
Property Tax in Washington
Washington property taxes are levied by counties, cities, school districts, and other taxing districts. The state imposes a levy limit. Effective property tax rates vary but average around 0.87-1.0% of assessed value.
How the Absence of an Income Tax Changes Planning
Most personal tax planning is built around reducing or deferring taxable income. Where the state does not tax income at all, a good deal of that reasoning simply does not apply, and planning shifts to a different set of questions.
Three things follow. Deductions and deferrals are worth their federal value only, so a strategy that looked compelling in a high-tax state is worth less here and should be re-evaluated rather than imported. Timing decisions that were about moving income between years matter less. And the taxes that do apply, on transactions, on business receipts and on estates, are the ones worth planning around, which is a different exercise entirely.
For a business owner the consequence is more pointed. Because the main business tax is charged on receipts rather than on profit, decisions that reduce taxable profit do nothing for it. Structuring, entity choice and the classification of activities matter more here than the deduction planning that dominates in other states.
- Re-test any planning imported from another state, rather than assuming it carries over
- Focus business planning on classification and structure, since the main business tax does not respond to deductions
- Remember the estate position, which is a genuine liability here and is often overlooked because the income position is not
- Take current thresholds and rates from the state department, because this area has been legislated on recently

Frequently Asked Questions
Does Washington State have a state income tax?
No state income tax on wages or most income. However, the 7% capital gains tax on gains over $250,000 functions as a de facto income tax on high earners with investment income (subject to the verify note above about its current status).
What taxes do Washington businesses pay?
The B&O tax on gross receipts (not net income), sales tax collection obligations, property tax, and payroll taxes. No corporate income tax.
Is Washington a good state for wealthy individuals?
Mixed. No income tax on wages is excellent. But the capital gains tax hits high earners with investment income, and the estate tax has a relatively low exemption. High property values in the Puget Sound region also push some estates over the threshold.
Why does the main business tax here surprise people?
Because it is charged on what you take in rather than on what you make. A business with a loss can still owe it, which is the opposite of how a profits tax behaves and is the single most common shock for a business arriving from another state. It also means that low-margin, high-volume businesses carry a proportionately heavier burden than the rate alone suggests.
Does a business outside the state have obligations here?
It can, depending on the extent of its activity and its sales into the state, and the answer does not require an office or staff here. The rules for out-of-state sellers have moved in recent years and differ between the business tax and the sales tax, so the position should be confirmed against the state's current guidance rather than a previous understanding.
