How to use Marriage Tax Calculator

Add the income figures for both people, and the calculator will estimate how the federal tax picture changes when those incomes are combined in a marriage filing scenario.

What this calculator is for

This calculator is for planning conversations about filing status and household finances. It offers a simplified federal comparison, not a complete return analysis, because credits, deductions, and state rules can alter the final result materially.

Tips

Use comparable taxable-income assumptions for both scenarios so the comparison focuses on filing-status differences rather than unrelated adjustments.
A federal marriage bonus or penalty does not automatically predict the total household tax result once state rules and credits are added.
