What Marriage Tax Calculator does

The Marriage Tax Calculator on Calculator.net estimates how getting married changes a couple's U.S. federal income tax bill. Users enter each spouse's income sources—such as salary, interest, dividends, and capital gains—along with deductions like mortgage interest and student loan interest, and the number of dependents. The tool then compares filing jointly as a married couple versus filing separately as single individuals, showing whether the marriage creates a tax bonus or penalty based on 2026 federal tax brackets.
