Supporters of President-elect Barack Obama's treasury secretary nominee say the sheen is still on the shining knight, even as critics wonder why the man who is supposed to oversee the nation's coffers failed to pay self-employment taxes for a housekeeper for four years

Senate Democrats had hoped to hold a Senate confirmation hearing for Timothy Geithner, who is president of the New York Federal Reserve Board, on Friday in anticipation of his needing to get seated quickly to deal with the stumbling economy. That would have been in violation of committee rules requiring a full week's notice before scheduling such a session.

That may now be rescheduled as Geithner faces increasing criticism that he should have known better about his tax obligations. An aide close to the confirmation process says that Sen. Jon S. Kyl of Arizona, the No. 2 Republican on the committee, has objected to a fast track for Geithner.

Geithner worked at the International Monetary Fund from 2001-2004, the years that his taxes were in arrears. He had been expected to pay employment taxes -- Social Security and Medicare -- for his housekeeper, who during his employment had let her immigration papers expire. The housekeeper later got a Green Card and the federal authorities decided not to prosecute her for the lapse in legal residency. 

But as a result of a 2006 audit, Geithner paid $16,732 in back taxes and penalties for the 2003-2004 period. Just before he was nominated, the Obama team found that he had failed to pay Social Security and Medicare taxes for the 2001-2002 period as well. Geithner ended up paying to the IRS $25,970 in back taxes and penalties for a total of $42,702 in late payments.

"There are a lot of people who are saying well if the top guy did it, I ought to be granted some leniency too," Sen. Arlen Specter, R-Pa., told FOX News on Wednesday. Specter said he doesn't want to prejudge the matter but he does want to look further into it. 

"This is not a trivial matter. The housekeeper is, but not the back taxes," Specter said.

Failing to pay taxes is apparently not so easy to do for employees of the IMF, which provides four documents to make sure the bank's employees stay current. The international lender based in Washington, D.C., provides an IMF Employee Tax Manual, a quarterly wage statement, a year-end wage statement and an annual tax allowance request, which employees submit in order to show how much they made, how much must be paid in taxes.

Tom Ochsenschlager, vice president of tax for the American Institute of Certified Public Accountants, said it would be difficult for someone preparing a tax return for a self-employed person to skip the Social Security and Medicare tax lines.

"It's such a basic mistake that I kind of wonder if we know all the facts," Ochsenschlager said.

John Berlau, director of the Center for Investors and Entrepreneurs, said the failure to pay the self-employment taxes is "astonishing." He called Geithner "unfit" to be in charge of the Treasury.

Unlike previous treasury secretary nominees, Geithner had not distinguished himself as a corporate leader or as an academic economist. His only significant policy accomplishment has been his role in the (President) Bush- (Treasury Secretary Henry) Paulson bailouts. And disturbing details are emerging about his misjudgments in this policy area as well," Berlau said, referring to the lack of oversight in the government's recent $700 billion bailout of the financial markets. 

Still, Geithner backers are hoping this blows over and the confirmation will proceed quickly. 

"Timothy Geithner is a person that is extremely well-qualified to be one of the finest secretaries of treasury this country has ever had, and there was a few little hiccups, and that's basically what they are. I am not concerned at all," said Senate Majority Leader Harry Reid.
