From Fox 5:
Undocumented workers in the US collected $4.2 billion in a certain tax credit last year, up from less than $1 billion five years ago, according to a new audit by the Treasury Department's Inspector General for Tax Administration revealed Friday.
The report looked only at a tax benefit known as the Additional Child Tax Credit, a refundable credit meant for working families. The audit found that as a result of vague US law -- as well as an expansion of the tax credit in stimulus legislation and other measures -- the number of illegal workers collecting the money has skyrocketed.
The inspector general's office expressed concern about the trend and urged the IRS and Treasury Department to determine once and for all whether that money should be paid out.
"The payment of federal funds through this tax benefit appears to provide an additional incentive for aliens to enter, reside and work in the United States without authorization, which contradicts federal law and policy to remove such incentives," the report said.
