Understanding IRS Identity Protection PINs: What They Are and How They Work

An IRS Identity Protection PIN, often called an IP PIN, is a six-digit number that helps prevent criminals from using your Social Security number to file fraudulent tax returns. The Internal Revenue Service created this program to protect people whose personal information has been compromised. When you have an IP PIN, you must enter it on your tax return along with your signature. Without the correct PIN, a fraudulent return using your Social Security number cannot be processed by the IRS.

The concept behind IP PINs is straightforward but powerful. Tax identity theft happens when someone files a false return in your name to claim a refund. The criminal uses stolen personal information—like your Social Security number—to make the fake return look legitimate. By requiring an IP PIN that only you know, the IRS creates an extra security layer. Even if someone has your Social Security number and other personal details, they cannot file a return without your PIN.

The IRS began offering IP PINs to people affected by data breaches at government agencies and companies. Over time, the program expanded to include anyone who has been a victim of tax-related identity theft. The agency has continued developing this tool because tax identity theft remains a serious problem. In recent years, hundreds of thousands of people have requested IP PINs.

IP PINs are not the same as passwords or PINs you might use for banking. The IRS does not store your PIN in a way that you would use it to log into their website. Instead, you receive a PIN that you write on your paper tax return or enter into tax software when filing electronically. The PIN serves as proof that you authorized the return being filed in your name.

Practical takeaway: Understanding what an IP PIN does—and what it does not do—helps you decide whether this tool is right for your situation. An IP PIN prevents criminals from filing returns in your name, but it does not protect your Social Security number in other contexts or prevent other types of identity theft.

Who Should Consider Getting an IRS Identity Protection PIN

Certain people have a higher risk of tax identity theft and should seriously consider obtaining an IP PIN. The IRS recommends IP PINs for anyone who has been a victim of tax-related identity theft in the past. If someone has filed a return using your Social Security number without your permission, or if the IRS has told you that a fraudulent return was filed in your name, an IP PIN can prevent it from happening again.

People who experienced data breaches at major companies or government agencies may also benefit from an IP PIN. When personal information is exposed in a breach—including names, Social Security numbers, and addresses—criminals often use that data to commit tax fraud. If you were affected by a significant breach, the organization may have notified you. An IP PIN offers one layer of protection while you monitor your information for other misuse.

You might consider an IP PIN if you have received IRS notices about unfiled or fraudulent returns. These notices include Form CP01.H (Notice of Underreported Income) or Form 12B (Notice of Deficiency). The presence of these notices suggests that someone may have filed in your name. The IRS also sends notices to people who file returns that do not match fraudulent ones already received.

High-risk individuals—such as people in data-heavy professions or those living in areas with high rates of tax fraud—may find an IP PIN useful. Business owners, healthcare workers, and government employees sometimes face elevated risks. Additionally, if you work in a field where your personal information is frequently exposed or shared, an IP PIN can reduce one specific identity theft risk.

Parents of dependent children may want to consider an IP PIN. Criminals sometimes file fraudulent returns claiming children as dependents to steal refunds. If your child's Social Security number is compromised, an IP PIN (obtained through the process for minors) protects that number from tax fraud.

Practical takeaway: Review your personal situation to determine your risk level for tax identity theft. If you have experienced tax fraud before, been affected by a data breach, or work in a high-risk profession, an IP PIN may provide meaningful protection for your tax filing.

How to Request an IRS Identity Protection PIN

The IRS offers multiple methods to request an IP PIN, making the process accessible to different people. The easiest and fastest method is through the IRS website at irs.gov. The IRS offers an online tool called the "IP PIN Request Tool" that allows you to request a PIN immediately if you meet certain requirements. To use this tool, you must verify your identity through an online authentication process. You will need to provide your Social Security number, filing status, and date of birth. The system confirms your identity and, if verification is successful, issues your IP PIN right away.

If you cannot use the online tool, you can request an IP PIN by mail. You would send Form 14039, Identity Theft Affidavit, to the IRS address listed in the form instructions. This process takes longer than the online method—often several weeks. You should mail the form as early as possible if you plan to file before the tax deadline, since the IRS needs time to process your request and issue your PIN before you file.

For people who have already filed a return and then discovered tax identity theft, the process differs. If someone filed a fraudulent return in your name, you file your own legitimate return and attach Form 14039 along with supporting documentation. This tells the IRS that you are the rightful taxpayer. The IRS investigates and works to resolve the fraud.

If you were affected by a known IRS data breach, the agency may have notified you and may offer to mail you an IP PIN automatically. You do not need to do anything in these cases—the PIN arrives in the mail. You simply use it when you file your next return.

The IRS also allows you to request an IP PIN by phone, though this method is less commonly used. You would call the IRS Identity Protection Specialized Unit. The phone number is available on the IRS website. Because phone lines experience high call volumes, wait times can be long.

When you request an IP PIN, the IRS asks for basic information to verify your identity. Be prepared to provide your Social Security number, date of birth, filing status, and possibly information from past tax returns. Having this information ready before you request a PIN makes the process quicker.

Practical takeaway: The online tool is the fastest way to request an IP PIN if you can verify your identity through the IRS website. If the online method does not work for you, the mail method is reliable but requires planning ahead so your PIN arrives before you file your return.

Using Your IP PIN When Filing Your Tax Return

Once you receive your IP PIN, you must use it every time you file a federal tax return. The process differs depending on whether you file on paper or electronically. If you file a paper return, you write your six-digit IP PIN in the space marked "IP PIN" on the front of Form 1040 (or whichever form you use). The PIN goes in a specific box on the return. Make sure the numbers are clear and legible so the IRS can read them correctly.

If you file electronically through tax software or a tax professional, the software will have a field for your IP PIN. You enter the six-digit number when the software prompts you. Electronic filing systems check that the IP PIN matches the one on file with the IRS. If the PIN does not match, the return is rejected, and you receive an error message. This rejection indicates that either the PIN was entered incorrectly or there is a mismatch between what you provided and what the IRS has on record.

It is important to keep your IP PIN in a safe place, just like you would keep important financial documents secure. Write it down and store it with your tax records, or save it in a password-protected file on your computer. Do not share your IP PIN with anyone, including family members, unless they absolutely need it to file your return. Tax preparers and accountants may need to know your IP PIN if you hire them to file your return on your behalf.

The IRS generates a new IP PIN for you each year. This means you will receive a different PIN for the next tax year. The IRS typically mails new PINs in the fall before the upcoming tax season. If you requested your first IP PIN, keep watch for the new PIN in the mail as tax season approaches. Set a reminder to check the mail or your online account to retrieve it before you file.
