IRS Finalizes Regulations on Truncated Taxpayer Identification Numbers

The Internal Revenue Service has issued final regulations on truncated taxpayer identification numbers, or TTINs, to safeguard against identity theft.

Where not prohibited by the Tax Code or other regulations or guidance, the final regulations allow use of a TTIN in lieu of a taxpayer’s Social Security Number (SSN), individual taxpayer identification number (ITIN), IRS adoption taxpayer identification number (ATIN), or employer identification number (EIN) on payee statements and certain other documents.
