Marriage Tax Calculator for Washington

Marriage tax effects in Washington are limited to federal changes, since there is no state income tax to create additional bonuses or penalties. At the federal level, two-earner couples can face a marriage penalty when their combined income pushes them into higher brackets, while single-earner couples often enjoy a marriage bonus from the doubled standard deduction. In Washington, these effects are purely federal, making the calculation cleaner. Use this calculator to compare your married and single federal tax bills in Washington.

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.
