Washington State is the 8th LEAST taxed state, as a percent of GDP.
The Department of Revenue has a webpage Comparative state and local taxes has tax charts comparing Washington with other states.
In the drop-down on that page if you choose “State and Local Taxes as % GDP” you can see that by that measure, Washington is the 8th least taxed state.
It makes sense: wealthier, productive states will pay more in taxes in absolute terms. But in relative terms, we pay little.
And if you choose “State and Local Taxes per $1,000 Personal Income” you’ll see that by that measure Washington is the 23rd least taxed state.
But, yes, you can lie with statistics, and the practical meaning of all this is difficult to gauge. Who pays the taxes? Who earns the income? Who benefits from the state spending that taxes enable? How well is the tax money spent?
For a different perspective, consider the Tax Foundation’s 2026 State Tax Competitiveness Index. In 2026 Washington State ranked as the
2nd highest sales tax (49 out of 50), after Louisiana
4th highest corporate tax
26th highest property tax
31st highest individual income tax. There’s no state income tax, so they must have considered the capital gains tax. Possibly the estate tax.
The fact that there’s no state income tax but the overall rank and sales tax rank are high shows how regressive Washington State’s tax system is.
In addition to considering the amount of tax, you have to consider income: if your income is higher, of course you can afford more taxes. Indeed, high-taxed states tend to have high incomes per capita.
