AHLSTARZ Tax and Accounting Service -- Numbers, Simplified.

More than 15 million taxpayers may see their refunds reduced or owe more in taxes when they file their 2009 and 2010 returns because of the Making Work Pay credit (MWPC), the Treasury Inspector General for Tax Administration (TIGTA) warned on November 16 ("Millions of Taxpayers May Be Negatively Affected by the Reduced Withholding Associated With The Making Work Pay Credit" (Reference No. 2010-41-002)). The MWPC is being advanced to taxpayers by employers through reduced withholding in 2009 and 2010.
