The U.S. Internal Revenue Service says it will allow all taxpayers to apply for an identity protection personal identification number (IP PIN) The IP PIN is a single-use code designed to block identity thieves from falsely claiming a tax refund in your name. Currently, IP PINs are issued only to those who fill out an ID theft affidavit, or to taxpayers whove experienced tax refund fraud in previous years. The IRS will make its Get IP PIN tool available to all taxpayers in mid-January.”]
