Marriage Bonus vs. Penalty
A marriage bonus occurs when one spouse earns significantly more—combined income is taxed at lower rates than if single. A penalty occurs when both spouses earn similar high incomes—you may hit higher brackets faster.
Filing Options
Married Filing Jointly usually offers lower rates and more deductions. Married Filing Separately rarely saves money but may be useful in specific situations (income-based loan repayment, liability protection).
Questions people ask
When does a marriage penalty occur?
When both spouses have similar high incomes. Two people earning $200K each pay about $1,350 more married, from the 0.9% Medicare surtax; bracket penalties start at the top 37% bracket.
Should we ever file separately?
Rarely for tax savings, but consider it for: income-driven student loan payments, keeping liability separate, or when one spouse owes back taxes.
