Understanding the Marriage Tax Penalty

When Penalties Occur

Marriage penalties typically occur when both spouses have similar, high incomes. The joint filing brackets are not exactly double the single brackets at higher income levels, causing couples to pay more than two single filers with the same individual incomes.

When Bonuses Occur

Marriage bonuses typically occur when one spouse earns significantly more than the other, or when one spouse has no income. The higher earner benefits from the wider tax brackets available to married couples filing jointly.

Married Filing Separately

This status rarely provides a tax benefit and eliminates access to many credits and deductions. It may be useful when separating, when one spouse has significant medical expenses, or to isolate tax liability from a spouse.
