A bill to amend the Internal Revenue Code of 1954 to reduce the tax effect known as the "marriage penalty".

Amends the Internal Revenue Code to allow a credit against the income tax for married individuals equal to the amount of tax imposed on their taxable earned income in excess of the sum of the amounts of tax that would have been imposed on each such individual if he or she were an unmarried individual (other than a surviving spouse or a head of household). Allows only half the full credit amount to each spouse if each files a separate return.
