W-4 Withholding Calculator for Washington

Since Washington has no state income tax, your W-4 only needs to account for federal withholding. This simplifies the form considerably: you focus on your filing status, dependents, and any additional income or deductions. Workers in Washington are less likely to be under- or over-withheld because there is no state form to coordinate with. Use this W-4 calculator to determine the right number of allowances and any extra withholding needed to hit your target refund or tax-due amount.

Washington is one of nine states with no personal income tax. Residents keep every dollar of earnings from state-level taxation, though the state generates revenue through other means such as sales taxes, property taxes, and in some cases severance taxes on natural resources. Washington does impose a 7% tax on capital gains exceeding $270,000, so high-net-worth investors should factor that in.

The table below shows what you actually keep at five salary levels in Washington, accounting for federal tax, FICA, and zero state income tax.
