Understanding the Marriage Tax
What is the Marriage Tax?
The marriage tax refers to the change in a couple's total tax liability when they marry and file taxes jointly, compared to filing as single individuals. This change can result in either a penalty (paying more tax) or a bonus (paying less tax).
When Does a Marriage Penalty Occur?
- Both spouses have similar high incomes
- Combined income pushes the couple into a higher tax bracket
- Deductions are limited for married couples
- Both spouses have significant itemized deductions
When Does a Marriage Bonus Occur?
- One spouse earns significantly more than the other
- One spouse has no income or very low income
- Combined standard deduction benefits the couple
- Ability to combine tax credits and deductions
