The IRS estimates that more than 20 percent of Earned Income Tax Credit (EI
TC) payments are made in error By matching the Current Population Survey (C
PS) to tax return data, this paper finds that a large portion oft he overpa
yments went to families with children. Depending on the exact measure used,
only 11 to 13 percent of EITC recipients lacked children in their househol
d at the time they received the EITC. While some of these erroneous payment
s to households with children are received by households with incomes above
EITC eligibility levels, many of these ineligible families with children a
ve likely to be quite similar to eligible EITC families.
