About This Calculator

The Marriage Tax Calculator helps couples understand whether they'll pay more or less in taxes by getting married. This calculator compares filing as two single individuals versus filing as a married couple.

Depending on your income levels, marriage can result in a tax penalty (paying more) or a tax bonus (paying less). This calculator helps you understand the financial impact of marriage on your taxes.

Formula & Calculation Method

Marriage Tax Calculation:

Single Filing Tax = Tax(Spouse1) + Tax(Spouse2)
Married Filing Tax = Tax(Combined Income)
Marriage Penalty = Married Tax - Single Tax (if positive)
Marriage Bonus = Single Tax - Married Tax (if positive)

The marriage penalty typically occurs when both spouses have similar high incomes. The marriage bonus usually occurs when one spouse earns significantly more than the other.

  3. Enter Deductions: Input total deductions (standard or itemized).

Frequently Asked Questions

What is the marriage tax penalty?

The marriage tax penalty occurs when a married couple pays more in taxes than they would if they filed as two single individuals. This typically happens when both spouses have similar high incomes.

What is the marriage tax bonus?

The marriage tax bonus occurs when a married couple pays less in taxes than they would if they filed as two single individuals. This often happens when one spouse earns significantly more than the other.

Can we file separately to avoid the penalty?

Married filing separately is an option, but it often results in higher taxes than filing jointly. The tax brackets for married filing separately are less favorable than single filing.

Does this include state taxes?

This calculator only estimates federal income tax. State tax implications of marriage vary by state and should be considered separately.
