2026 Washington Income Tax Calculator
Washington and Federal Calculation Assumptions
Income
- This calculator assumes you are a Washington resident for the full 2026 tax year. Partial-year resident and nonresident income allocation rules are not included.
- We treat household income as earned wage income. We do not separately calculate self-employment income, investment income, retirement income, capital gains, or other special income categories that require different tax treatment.
- The
Other Income Deductions
field under Advanced Options reduces federal adjusted gross income. See the input field tooltip for more details.
Deductions
- The calculator compares itemized deductions with the standard deduction separately, then uses the larger allowed amount for federal tax.
- Age 65+ and blindness selections increase the standard deduction amount when applicable.
- The federal enhanced senior deduction is calculated separately and may still apply when itemizing.
- Itemized deduction inputs mirror the categories reported on Form 1040 Schedule A. Use prior-year amounts as a starting point and adjust for expected changes.
- The federal calculation applies the 2026 SALT limit and its income-based phaseout before adding deductible interest and other itemized deductions.
- Qualified tips, overtime pay, car loan interest, and the enhanced senior deduction are treated as federal deductions after adjusted gross income.
Credits
- We estimate the federal Child Tax Credit (CTC) and Additional Child Tax Credit (ACTC) for dependent children under age 17.
- We estimate the federal Earned Income Tax Credit (EITC) only when at least one dependent child under age 17 is entered. The estimate does not include the childless EITC or qualifying children who are older students or permanently disabled.
- We do not calculate the Saver's Credit, education credits, premium tax credits, or other federal credits.
Taxes Not Included
- Washington individual income tax is estimated at $0 because the state does not impose a personal income tax on wages or ordinary individual income.
- The calculator does not calculate Washington's separate capital gains tax. If you have taxable long-term capital gains, review Washington Department of Revenue guidance separately.
- No local individual income tax calculation is included here.
- The estimate does not include self-employment tax, federal alternative minimum tax, federal capital gains tax, use tax, or every federal deduction and credit.
Actual results may vary based on your income type, additional deduction and credit limits, filing complexity, and continued changes in Washington or federal tax law. This calculator provides an estimate for general planning purposes and does not guarantee your final tax due or refund amount.
How the Washington Income Tax Calculator Works
The Washington income tax calculator shows each major step from household income to estimated tax. The results compare Washington and federal income taxes. The Washington column remains at $0, while the federal column applies federal standard or itemized deductions, tax credits, and deductions created by the One Big Beautiful Bill Act (OBBBA).
The final three rows summarize your Washington results:
- Estimated Income Tax: Your Washington income tax estimate for the year.
- Effective Tax Rate: Washington income tax as a percentage of household income.
- Marginal Tax Rate: The Washington tax rate applied to your next dollar of taxable income.
Change any calculator input to see how it affects the federal results. The Washington column remains at $0 because Washington does not impose a personal income tax on wages or ordinary individual income.
Washington Income Tax
Washington does not impose an individual state income tax on wages or ordinary individual income for the 2026 tax year. The Washington income tax rate shown in this calculator is 0%, and residents do not move through state income tax brackets as income increases. Filing status does not change the Washington result: Single, Married Filing Jointly, Married Filing Separately, and Head of Household filers all have an estimated Washington individual income tax of $0.
Because Washington has no broad individual income tax, the state does not use personal exemptions, standard deductions, itemized deductions, or state income tax credits for wage income tax purposes. Federal income tax rates still apply, so income that is not taxed by Washington may still be taxable on your federal return.
Washington Capital Gains Tax
Washington has a separate capital gains tax on certain long-term capital gains above the annual deduction amount. The Washington Department of Revenue describes this tax separately from a general personal income tax, and only individuals who owe the capital gains tax must file a Washington capital gains tax return. This calculator does not calculate Washington capital gains tax.

Washington has no wage income tax brackets: The state result is $0 at every income level and for every federal filing status.
Federal taxes still apply: Washington residency does not eliminate federal income tax, federal payroll tax, or other federal tax obligations.
Capital gains may need separate review: Washington's capital gains tax is not included in this calculator and may apply to certain long-term gains above the annual deduction amount.
