What is Marriage Tax?

Marriage tax refers to the difference in federal income tax liability between filing as a married couple versus filing as two single individuals. This can result in either a "marriage penalty" (paying more tax) or a "marriage bonus" (paying less tax) depending on the income levels and filing status of both spouses.

The marriage penalty typically occurs when both spouses have similar incomes, while the marriage bonus often occurs when there's a significant income disparity between spouses. This calculator helps you understand the potential tax implications of marriage based on 2025 federal tax brackets.
