IRS: IP PIN valid for 2015 returns

Due to an error, taxpayers are receiving Identity Protection PIN letters with an incorrect year listed. Taxpayers and tax professionals should be advised the IP PIN listed on the CP 01A Notice dated January 4, 2016 is valid for use on all individual tax returns filed in 2016.
The notice incorrectly indicates the IP PIN issued is to be used for filing the 2014 tax return when the number is actually to be used for the 2015 tax return.  The IRS emphasizes the IP PIN listed on the CP 01A notice is valid for the 2015 returns. Taxpayers and their tax professionals should use this PIN number for 2015 tax returns, which the IRS will begin accepting from taxpayers starting Jan. 19, 2016.
The IRS apologizes for the confusion and any inconvenience.
