About the Washington Paycheck Calculator
Washington has no state income tax on wages. Workers in Washington owe only federal income tax, Social Security, and Medicare on their wages. This calculator gives you an accurate federal take-home pay estimate for Washington State workers. (Note: Washington imposes a 7% capital gains tax above $270,000 on certain investment income - that's separate from wages.)
Washington's state income tax is computed after deducting Washington's standard deduction ($2,500 single / $7,500 married) and personal exemption ($1,500 single / $3,000 married). The top 5% rate kicks in on income above $3,000 for single filers and $6,000 for married filers - meaning most Washington workers pay an effective rate close to 5% on the majority of their income.
Note: Several Washington cities including Birmingham and Gadsden impose local occupational taxes (1–2%) not included in this calculator. Jefferson County also has a 1% occupational tax. Check with your employer for local withholding amounts. These results are bracket-based estimates only.
