An in-depth look at the Marriage Penalty, a tax law provision requiring some married people to pay more in taxes than if they were single.

On this page

The Marriage Penalty refers to various provisions within tax law that result in married couples paying more in taxes under certain conditions than if they were single. The penalty is particularly significant for high-income couples who earn similar amounts. This phenomenon occurs despite married filers having the option to file separately, as the total tax liability generally does not match, and may exceed, the combined taxes had both individuals remained single and filed as such.

Key Features of the Marriage Penalty

Tax Bracket Disparities

When two individuals with comparable incomes marry, their combined income may push them into a higher tax bracket compared to when they were filing as single filers. In the U.S., the tax brackets for married joint filers are not always perfectly double those of single filers, especially at higher income levels.

Deductions and Credits

Several tax deductions and credits are structured in a way that they phase out or become limited at lower income thresholds for married couples compared to single filers. Examples include the Earned Income Tax Credit (EITC) and the Child Tax Credit.

Alternative Minimum Tax (AMT)

Married couples are more likely to be subject to the Alternative Minimum Tax (AMT). This is a separate tax system designed to ensure that high-income individuals pay at least a minimum amount of tax, but its structure can disproportionately affect married filers.

Historical Context

The concept of the marriage penalty dates back to the introduction of progressive income tax systems, where the tax burden increases with income. Originally, the U.S. tax system was more neutral towards marital status, but as the progressive structure evolved, discrepancies inevitably emerged.

Comparisons with Other Tax Systems

Community Property States

In community property states, where assets and income acquired during marriage are considered jointly owned, the impact of the marriage penalty can differ significantly compared to separate property states.

International Examples

Many countries have their unique approaches to taxing married couples, some offering splitting options where income can be divided equally between spouses for tax purposes, thereby mitigating the penalty.

Marriage Bonus: In some cases, married couples may pay less tax than their single counterparts, particularly when one spouse earns significantly more than the other.
Head of Household: A filing status that may apply to single filers with dependents, often providing greater tax benefits than the single filer status.
