The scandal involves a program known as the Earned Income Tax Credit. It is an anti-poverty program in which the government gives low-income workers a tax refund larger than their tax liability. For example, a family with a $1,000 income tax liability might qualify for a credit four times that large, and receive an Earned Income Tax Credit payment of $4,000. Another family with no income tax liability at all might qualify for the same lump-sum payment. Call it a subsidy, a refund, a transfer payment — in any case, the family receives a check from the feds.
