A couple suffers a “marriage penalty” if its partners pay more income tax as a married couple than they would have as two single individuals. Conversely, the couple receives a “marriage bonus” if its partners pay less income tax as a married couple than they would have as two single individuals. This calculator lets you see whether couples in particular situations receive tax penalties or bonuses from marriage. For more information on marriage penalties and bonuses, see this TPC Tax Topic.
NOTE: This calculator compares the taxes a married couple would pay filing a joint return with what they would pay if they were not married and each filed as single or head of household. It does not compare the taxes a married couple would pay filing jointly versus filing separately.
