Marriage Penalty vs. Bonus
A marriage penalty occurs when a couple pays more in taxes filing jointly than they would as two single filers. A marriage bonus occurs when they pay less. Couples with similar high incomes are more likely to face a penalty, while couples with one high earner and one low/no earner often receive a bonus.
