Tax identity theft continues to affect thousands of Americans each year. A fraudulent tax return filed under your Social Security number can delay legitimate refunds for months while the Internal Revenue Service investigates the matter. Fortunately, the IRS offers a simple but powerful security tool known as the Identity Protection Personal Identification Number (IP PIN).

An IP PIN is a six-digit number assigned by the IRS that helps verify the identity of a taxpayer when a federal income tax return is filed. Understanding how an IP PIN works can substantially reduce the risk of tax-related identity theft.

What Is an Identity Protection PIN?

An Identity Protection PIN is a six-digit number issued by the IRS that must be included on a taxpayer’s federal income tax return before the IRS will accept the return for processing.

Without the correct IP PIN, an electronically filed tax return generally will not be accepted, and a paper return will require additional verification before processing.

The IRS originally limited IP PINs to confirmed victims of identity theft. Today, however, most taxpayers with a Social Security Number or Individual Taxpayer Identification Number may voluntarily request one.

Congress Has Authorized Identity Verification Measures

Congress has directed the Treasury Department to implement procedures that protect taxpayers and improve tax administration.

For example, 26 U.S.C. § 6103 generally protects the confidentiality of tax returns and return information, reflecting Congress’s strong policy that taxpayer information should remain secure.

Likewise, Treasury Regulation § 301.6109-1 authorizes the IRS to prescribe identifying numbers and procedures necessary for tax administration. These identity verification procedures include assigning identifying numbers and requiring taxpayers to furnish them when filing returns.

Together, these authorities provide the legal framework for IRS identity verification programs such as the Identity Protection PIN.

How Does an IP PIN Work?

Each calendar year, the IRS generates a new six-digit PIN.

When preparing a federal tax return, the taxpayer enters that number before filing.

If a criminal attempts to file a fraudulent return using the taxpayer’s Social Security number but does not know the correct IP PIN, the IRS generally rejects the electronically filed return.

This prevents many forms of refund fraud before they begin.

Who Should Consider Getting One?

While virtually anyone may benefit from an IP PIN, it can be especially valuable for:

• Individuals who have previously experienced identity theft.
• Taxpayers whose personal information has been exposed in a data breach.
• Retirees who expect significant refunds.
• Self-employed individuals.
• Business owners.
• Professionals whose publicly available information makes them more attractive targets for identity thieves.
• Anyone simply wishing to add another layer of security to their tax filings.

Advantages of an IP PIN

An IP PIN offers several important benefits:

• Reduces the likelihood of fraudulent tax returns.
• Helps prevent refund theft.
• Gives taxpayers greater confidence that only authorized returns will be processed.
• Adds an additional authentication factor beyond a Social Security number.
• Is free through the IRS.

Because Social Security numbers are frequently compromised through unrelated data breaches, relying on the SSN alone no longer provides meaningful protection.

Are There Any Downsides?

The primary drawback is that taxpayers must use the correct IP PIN every year.

Because a new PIN is issued annually, taxpayers should carefully retain the current year’s number. Filing without the correct PIN may delay processing while the IRS verifies the taxpayer’s identity.

Fortunately, replacement procedures exist if the PIN is misplaced.

Does an IP PIN Affect State Tax Returns?

An IP PIN is an IRS security measure for federal income tax returns.

Some states have their own identity verification procedures, while others simply rely upon their existing fraud detection systems.

Taxpayers should review the filing requirements of their individual state.

How to Obtain an IP PIN

Most taxpayers can obtain an IP PIN directly from the IRS after completing the agency’s identity verification process.

The process generally requires verification of the taxpayer’s identity before the annual PIN is issued.

Once enrolled, taxpayers should continue using the newly issued IP PIN for each subsequent filing season.

Final Thoughts

Tax identity theft can create months of frustration, delayed refunds, and unnecessary correspondence with the IRS. Fortunately, obtaining an Identity Protection PIN is one of the simplest preventive measures available.

Although no security system is perfect, adding an IP PIN creates a substantial obstacle for criminals attempting to file fraudulent returns using your Social Security number. For many taxpayers, it is one of the easiest—and most effective—steps they can take to protect themselves during tax season.
