Taxpayers have been receiving letters with incorrect Identity Protection PIN numbers from the IRS. Notices are listing an incorrect filing year, the agency reported, which has created confusion for many taxpayers and tax professionals. According to a statement updated on January 15, 2016, the PIN numbers issued are, in fact, valid for filing year 2015 (despite the filing year being listed as 2014).

The misleading notices were mailed in December, though they are dated January 4, 2016. Follow-up notices have already been issued to correct the misinformation.
