Rude surprise coming for some taxpayers. You will have to pay back some of your Obama tax credit.

Are you happy Obama is giving you a small boost in your paycheck via his tax credit? How will you feel if you have to give part of it back when you file your taxes after the first of the year. That is exactly what will happen to some people due to changes in IRS tax withholding tables. Those at highest risk are married couples with two wage earners; workers with more than one job; retirees who have federal income taxes withheld from their pension payments and Social Security recipients with jobs that provide taxable income. Yahoo Finance reported:

WASHINGTON (AP) -- Millions of Americans enjoying their small windfall from President Barack Obama's "Making Work Pay" tax credit are in for an unpleasant surprise next spring.

The government is going to want some of that money back.

The tax credit is supposed to provide up to $400 to individuals and $800 to married couples as part of the massive economic recovery package enacted in February. Most workers started receiving the credit through small increases in their paychecks in the past month.

But new tax withholding tables issued by the IRS could cause millions of taxpayers to get hundreds of dollars more than they are entitled to under the credit, money that will have to be repaid at tax time.

At-risk taxpayers include a broad swath of the public: married couples in which both spouses work; workers with more than one job; retirees who have federal income taxes withheld from their pension payments and Social Security recipients with jobs that provide taxable income.

The Internal Revenue Service acknowledges problems with the withholding tables but has done little to warn average taxpayers.

"They need to get the Goodyear blimp out there on this," said Tom Ochsenschlager, vice president of taxation for the American Institute of Certified Public Accountants.
