Depending on how a couple's incomes compare, filing jointly can result in either a "marriage penalty" (paying more combined tax than as two singles) or a "marriage bonus" (paying less).
This calculator compares your combined tax filing jointly against what you'd each pay filing single, using 2024 federal tax brackets.
How it works
Enter each spouse's annual income. The calculator computes tax three times: once on the combined income using Married Filing Jointly brackets, and once on each individual income using Single brackets — then compares the totals.
- Enter spouse 1's annual income ($).
- Enter spouse 2's annual income ($).
- Click Calculate to see your results.
Examples
Two equal incomes of $60,000 each
Two spouses each earning $60,000 pay exactly the same total tax ($10,432) whether filing jointly or as two singles — a neutral result, since equal incomes at this level fall within proportionally matching brackets.
Who should use it
- Understanding the tax impact of marriage before or after a wedding.
- Comparing filing statuses for tax planning purposes.
Industry applications
- Tax planning and preparation
- Personal finance and marriage financial planning
Advantages
- Directly compares all three tax scenarios (joint, and each spouse single) using accurate 2024 bracket figures.
- Clearly labels the result as a penalty, bonus, or neutral outcome.
Limitations
- Simplified estimate using only the standard deduction — doesn't include itemized deductions, credits, or other income types.
Common mistakes to avoid
- Assuming marriage always creates a tax penalty — for unequal incomes, it very often creates a bonus instead.
- Forgetting this is a simplified comparison using only the standard deduction, without itemized deductions or credits.
Best practices
- Try entering your specific incomes rather than assuming a penalty or bonus — the result depends heavily on how the two incomes compare.
Tips
- The marriage penalty or bonus tends to be largest at income levels where combined income crosses into a meaningfully higher tax bracket than either individual income would alone.
