Washington versus the states next-most-affordable for taxes
Other US states ranked just above Washington on the $100K single-filer state-tax burden, the next tier of "low-tax" jurisdictions.
Because Washington has no state income tax, the meaningful comparison isn't "neighbors above and below" (everyone with tax is "above" us at any income level) - it's the nearest tier of low-tax states a Washington resident might compare against if they relocated. Each card below shows that state's top marginal rate, structure, and the dollar burden a $100K single filer would face. Compared to Washington's $0, the gap is the cost-of-tax of moving away from one of the nine no-income-tax jurisdictions.

How this calculator works
This calculator applies Washington's progressive tax brackets to the income you enter, moving each dollar through the correct marginal rate until the full amount is accounted for. The effective rate shown at the bottom is the total tax divided by gross income, a useful number for budgeting because it represents what you actually pay on every dollar earned, not just the headline marginal rate. We never apply a flat percentage to total income. Standard deductions and common adjustments are applied in the same order the tax authority applies them, so the result matches the official calculation within rounding error. If you file jointly, select the joint filing status, brackets widen substantially and the difference is meaningful for middle-income households.
Required inputs: gross income, filing status.
