. . . for two-thirds of the provisions:
The Treasury Inspector General for Tax Administration today publicly released its review of the IRS’s ability to verify taxpayer eligibility for tax benefits and credits provided by the American Recovery and Reinvestment Act of 2009. The Recovery Act contains 56 tax provisions with a potential cost of more than $325 billion that are intended to provide tax relief for individuals and businesses. . .
TIGTA found that the IRS is unable to verify taxpayer eligibility for the majority of Recovery Act tax benefits and credits at the time a tax return is processed. This includes 13 of the 20 benefits and credits for individual taxpayers and 26 of the  tax provisions benefiting businesses.
So two-thirds of the stimulus bill’s tax provisions are invitations for fraud. But why should Congress worry about this? It’s not as though it’s their money being wasted. . .
