Compares two single filers vs one married-filing-jointly return. Based on 2026 tax rates. Does not account for credits, deductions, or married-filing-separately.
How it works
This calculator compares two tax scenarios: (1) both spouses filing as single individuals on their own income, and (2) filing jointly on their combined income using married-filing-jointly brackets.
Marriage penalty: Occurs when joint filing results in more tax than two separate single returns. This happens because the married brackets at higher income levels are not exactly double the single brackets, so two similar high incomes get pushed into higher brackets faster.
Marriage bonus: Occurs when joint filing results in less tax. This typically happens with income disparity — the lower earner's income fills the bottom of the joint brackets at lower rates, while as a single filer the higher earner's income was already in a high bracket.
The calculation includes federal income tax, state income tax, Social Security, and Medicare. FICA taxes are calculated individually for each spouse in both scenarios.
FAQ
What is the marriage tax penalty?
When a married couple pays more in taxes filing jointly than they would as two single filers. Common when both spouses earn similar high incomes.
When do we get a marriage bonus?
When there is a large income disparity between spouses. The lower earner's income fills the bottom brackets at lower rates, reducing overall tax.
Is married filing separately better?
Rarely. MFS uses narrower brackets and disqualifies many credits and deductions. It is occasionally beneficial in specific situations (e.g., high medical expenses). This calculator compares single vs joint, not MFS.
How can I reduce the marriage penalty?
Maximize pre-tax deductions (401(k), HSA), consider timing income across years, and ensure you are using all available credits. The penalty is built into the bracket structure, so options are limited.
Should I file married filing jointly or separately?
For most couples, filing jointly results in lower taxes due to wider tax brackets and a higher standard deduction ($$32,200 vs $$16,100 each). Filing separately may save money when one spouse has large medical expenses, student loan payments under IBR, or when one spouse owes back taxes. Use this calculator to compare both scenarios with your actual incomes.
What is the difference between filing jointly and separately?
Filing jointly combines both spouses' incomes on one return with wider brackets and a $$32,200 standard deduction. Filing separately means each spouse files their own return with narrower brackets and a $$16,100 deduction. Joint filing usually results in less total tax, but there are exceptions — this calculator shows you exactly how much you'd save or lose.
