Marriage can raise or lower a couple's federal income tax. Enter both spouses' incomes and the calculator compares the tax filing jointly against the total if each filed as a single, revealing a marriage penalty (you pay more) or bonus (you pay less). It uses the 2025 federal brackets and standard deduction for a clear estimate.

Frequently asked questions
What is the marriage penalty?
When a couple pays more filing jointly than they would as two singles — most common when both earn similar high incomes. This tool shows your exact figure.
Is there a marriage bonus?
Yes — couples with very different incomes often pay less jointly, because the higher earner's income is taxed at lower brackets when combined.
