As tax-related identity theft continues to be a significant concern, the Internal Revenue Service (IRS) is encouraging taxpayers to take advantage of the Identity Protection Personal Identification Number (IP PIN) program as an effective safeguard against fraudulent tax return filings.

An IP PIN is a unique six-digit number known only to the taxpayer and the IRS that must be included on federal income tax returns to verify the taxpayer's identity. Once issued, the IP PIN prevents identity thieves from filing a fraudulent tax return that uses the taxpayer's Social Security number or Individual Taxpayer Identification Number (ITIN), even if the taxpayer is not otherwise required to file a return.

The IP PIN program is available at no cost to any individual with a Social Security number or ITIN who can successfully verify their identity with the IRS, including taxpayers residing outside the United States. The fastest method of enrollment is through an IRS Individual Account. Taxpayers who cannot complete the online verification process may be qualified to apply using Form 15227 or may complete their identity verification in person at a Taxpayer Assistance Center.

The IRS also reminds taxpayers that a new IP PIN is generated each year and must be retrieved annually before filing a federal return. The IP PIN must be included on all federal tax returns filed, including any amended returns.

An omitted or incorrect IP PIN may result in the rejection of an electronically filed tax return or possible delays in processing a paper return while the taxpayer's identity is verified. It is important to note that the IRS will never contact taxpayers by phone, email, text message or social media to request an IP PIN.
