Millions will have to repay part of tax credit

More than 15 million taxpayers may owe the government $250 or more because of how the IRS last spring set up President Barack Obama's tax break that was designed to help consumers spend the U.S. economy out of recession.

Individuals with more than one job and married couples in which both spouses work may have to repay the government $400, either through a smaller tax refund or a larger tax bill, according to a report released Monday by the Treasury Department's inspector general for tax administration. Social Security recipients who also earn taxable wages may have to repay $250.
