This marriage tax calculator compares your 2026 federal income tax as two single filers with your tax as a married couple filing jointly. It uses the 2026 brackets and standard deductions to show whether marriage gives you a tax bonus (usually when incomes are very different) or a penalty (more likely when both earn high, similar incomes).
What is a Marriage Tax Calculator?
When you marry, the IRS treats you as married for the whole year if you are married on 31 December, and most couples file jointly. Their incomes are combined and taxed using the married brackets and standard deduction, which are double the single figures for most brackets.
Because of this, couples with very different incomes often pay less (a marriage bonus), while couples with two high, similar incomes can pay more in the top brackets (a marriage penalty). This marriage tax calculator compares the two situations using 2026 figures.
How does the Marriage Tax Calculator work?
The calculator applies the 2026 standard deduction and brackets to each partner as an unmarried filer (single or head of household) and adds the two tax bills. It then applies the married filing jointly deduction and brackets to the combined income. The difference is the penalty or bonus.
How to use the Marriage Tax Calculator step by step
- Enter partner 1’s income and filing status if unmarried.
- Enter partner 2’s income and filing status.
- Read the tax as two unmarried filers.
- Read the married filing jointly tax.
- See the penalty or bonus.
- Use the result to plan withholding after the wedding.
Marriage Tax Calculator example with real numbers
Sam earns $90,000 and Jordan earns $50,000. Both file single today and plan to marry before 31 December 2026.
| Example input | Value |
|---|---|
| Partner 1 income (wages and other taxable income) | $90,000 |
| Partner 1 status if unmarried | Single |
| Partner 2 income | $50,000 |
| Partner 2 status if unmarried | Single |
| Example output | Value |
|---|---|
| Marriage bonus | $1,650 |
| Partner 1 tax (unmarried) | $10,970 |
| Partner 2 tax (unmarried) | $3,820 |
| Total as two unmarried filers | $14,790 |
| Married filing jointly | $13,140 |
| Marginal rate: married | 22% |
| Marginal rates unmarried | 22% and 12% |
As two single filers they would pay $14,790. Filing jointly they would pay $13,140, so the marriage tax calculator shows a $1,650 marriage bonus.
