Tax-related identity theft can hijack a refund and tangle a person in months of paperwork, all because a thief filed a fraudulent return using a stolen Social Security number. The IRS offers a free tool that shuts that door: a personal identification number that must accompany any return filed in a person’s name. Once it is in place, a return without the correct number is rejected.
How the IP PIN protects a taxpayer
The Identity Protection PIN is a six-digit number known only to the taxpayer and the IRS. The agency’s guidance on how to get an Identity Protection PIN explains that once a taxpayer has one, the IRS will not accept an electronically filed return, and will flag a paper return, unless it includes the correct PIN. That requirement blocks a thief who has a person’s name and Social Security number but not the secret number.
The protection is significant because tax-related identity theft typically works by filing early with stolen information to claim a refund before the real taxpayer files. The IRS’s identity theft resources describe how these schemes operate and how the PIN interrupts them. With a valid PIN required, a fraudulent return is stopped at the door rather than discovered after a refund has been paid to a criminal.
A new PIN is generated each year, and the taxpayer retrieves the current one before filing. This annual refresh means a number stolen in one year does not help a thief in the next, keeping the safeguard current.

Who can get one and how
The program is open to any taxpayer who can verify their identity, not only to those who have already been victims of identity theft. It began as a tool for confirmed victims and has since been expanded so that anyone wanting the extra protection can opt in voluntarily. That shift makes it a proactive defense rather than only a remedy after a theft.
Enrolling is done primarily through an online tool on the IRS website, which requires verifying identity through a secure process. Taxpayers who cannot verify online may have alternative ways to obtain a PIN, depending on their situation. Once enrolled, the taxpayer simply includes the assigned number when filing, whether doing so personally or through a tax preparer, who will need the number to submit the return.
Keeping the PIN safe
Because the number is the key to the protection, guarding it is essential. The IRS never asks for the Identity Protection PIN by phone, email, or text, and any such request is a scam. The number should be shared only when actually filing a return, and only with a trusted tax preparer if one is used. Treating it like a password, kept private and entered only on the legitimate return, preserves its value.
The IRS’s reminders on how to protect personal and tax information reinforce that the agency does not initiate contact demanding sensitive numbers, and that unsolicited requests for the PIN are fraudulent. Recognizing that any caller or message asking for it is an impostor is part of using the tool safely.
A worthwhile step for retirees
For older adults, who are frequent targets of identity theft, the Identity Protection PIN is a low-effort, no-cost way to lock down the tax account against one of the more disruptive forms of fraud. Enrolling once, retrieving the new number each year before filing, and keeping it confidential adds a strong barrier that a thief cannot easily overcome even with a stolen Social Security number.
The broader takeaway is that tax identity theft, while damaging, is largely preventable with this safeguard in place. A retiree who obtains an Identity Protection PIN, guards it carefully, and includes it on each year’s return makes it far harder for anyone to file a fraudulent return in their name, protecting both the refund they are owed and the peace of mind that comes with a secure tax account.
How it fits with other tax protections
The Identity Protection PIN is the strongest single safeguard against a fraudulent return, but it works best as part of a broader habit of protecting tax information. Filing early, before a thief has the chance to file a fraudulent return in someone’s name, reduces the window of opportunity. Guarding the Social Security number, being wary of unsolicited requests for personal information, and using secure methods to file and store tax documents all reduce the raw material a thief could exploit.
Recognizing tax-season scams is part of the same effort. Impersonators posing as the tax agency may call, email, or text demanding immediate payment or personal details, but the agency generally initiates contact by mail and does not demand payment through gift cards or wire transfers, or threaten immediate arrest. Treating any such urgent demand as a scam, and never sharing the Identity Protection PIN in response to one, keeps both the tax account and the PIN secure.
A worthwhile safeguard
For older adults, who are frequent targets of identity theft, the Identity Protection PIN is a low-effort, no-cost way to lock down the tax account against one of the more disruptive forms of fraud. Enrolling once through the Internal Revenue Service’s Identity Protection PIN program, retrieving the new number each year before filing, and keeping it confidential adds a strong barrier that a thief cannot overcome even with a stolen Social Security number. Tax identity theft, while damaging and time-consuming to resolve, is largely preventable with this safeguard in place, protecting both the refund a person is owed and the peace of mind of a secure tax account. Obtaining the number once, retrieving the new one each year before filing, and keeping it strictly confidential add a durable barrier that a thief cannot overcome even with a stolen Social Security number, all at no cost.
