SSN ER: Progress on IRS Systems, Forms, Notices and Letters

The IRS's Social Security Number Elimination and Reduction (SSN/ER) Program has made significant strides in eliminating or reducing the use of SSNs within our systems, forms, notices and letters where the collection or use of the SSN was not necessary. We met the OMB 07-16 mandate to complete a review of the use of SSNs in all IRS Federal Information Security Management Act (FISMA) and non-FISMA systems. We also identified instances where the collection or use of the SSN was not necessary.


Full SSN not used on 20.4 Million Outgoing Non-Payment Notices Annually
We have redacted the Social Security numbers from 58 outgoing non-payment notices mailed to taxpayers. As of January 2013, 20.4 million notices have been sent to taxpayers.


Full SSN not used on 7.3 Million Automated Collection System letters
We redacted Social Security numbers on numerous taxpayer sensitive, collection and enforcement related letters. For FY 2012, the SSNs were completely removed on 7.3 million collections notices.


IRS Truncated Taxpayer Identification Number (TTIN)  
A TTIN is an alternative to using a social security number (SSN), IRS individual taxpayer identification number (ITIN), or IRS adoption taxpayer identification number (ATIN).  The filer of certain information returns may use a TTIN on the corresponding payee statements to identify the individual being furnished a statement. The TTIN displays only the last four digits of an individual’s identifying number and is shown in the format XXX-XX-1234 or ***-**-1234.
