Does Your State Have a Marriage Tax Penalty?
Under a progressive, graduated-rate income tax system, tax rates increase as a taxpayer’s marginal income increases. A marriage penalty exists when a state’s income brackets for married taxpayers filing jointly are less than double the bracket widths that apply to single filers. In other words, married couples who file jointly under this scenario face a higher effective tax rate than they would if they filed as two single individuals with the same amount of combined income.
This nonneutral tax treatment is particularly harmful to owners of pass-through businesses, who pay taxes on their business income under the individual income tax system. Under a marriage penalty, married business owners are subject to higher effective tax rates on their business income than they would be otherwise.
