Seems it’s not just White House appointees who struggle with tax delinquencies.

At a House panel hearing today, Rep. John Lewis (D-Ga.), who heads the Ways & Means Oversight Subcommittee, revealed the results of the panel’s investigation into the top recipients of federal help under the Wall Street bailout.

The results: 13 of the top 23 recipient companies owe back-taxes totaling more than $220 million. Two of the companies owe more than $100 million each. “How can this be?” Lewis asks in a statement. “If we looked at all 470 recipients, how much would they owe?”

Testifying before the panel was the bailout’s chief overseer, Neil Barofsky, who told lawmakers that the companies, as a condition of receiving TARP funds, must affirm that their tax payments are current, according to the release.

Lewis was quick to point out that federal law prevents the panel from revealing which companies are delinquent. He also made it clear that the Treasury Department, though asked to testify before the panel, declined its invitation.

And here we thought only the Bush administration did that.
