How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

A marriage tax penalty occurs when a couple pays more tax filing jointly than they would as two separate single filers. A marriage bonus occurs when filing jointly results in lower combined tax. This calculator compares both scenarios using 2024 US federal tax brackets.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

What causes a marriage tax penalty?

A marriage penalty often occurs when two high earners marry because the married brackets are not exactly double the single brackets at higher income levels.

What causes a marriage tax bonus?

A marriage bonus typically occurs when one spouse earns significantly more than the other. The lower-earning spouse's income is taxed at a lower combined rate when filing jointly.
