Quick answer
An IRS Identity Protection PIN is a six digit number that must appear on your tax return for it to be accepted. Without it, a fraudulent return filed in your name is rejected. Any taxpayer can opt in through the Get an IP PIN tool in their IRS Online Account, and the number changes every year.
Tax-related identity theft works because filing a return requires very little that is actually secret. A name, a Social Security number, and a date of birth are enough, and all three are widely available after two decades of data breaches.
An Identity Protection PIN closes that gap. It adds a number the IRS knows and a thief does not, and without it an electronically filed return in your name is rejected outright. It costs nothing and takes about ten minutes.
What an IP PIN Actually Does
It moves you from detecting fraud afterward to preventing it up front.
Without an IP PIN
- A thief files early using your Social Security number
- They claim a refund and it gets paid
- Your real return is rejected as a duplicate
- You file Form 14039 and switch to paper
- Your legitimate refund is delayed, often for months
With an IP PIN
- A thief files without the number
- The return is rejected immediately
- No fraudulent refund is issued
- Your return processes normally
- You never find out it happened
Three Ways to Get One
Only the first is immediate.
Online, same day
Use the Get an IP PIN tool inside your IRS Individual Online Account. Identity verification requires a photo ID and, usually, a selfie match. The number appears immediately once you are through. This is the route to use.
Form 15227, by mail
Available if your income is below the published threshold and you cannot verify online. The IRS calls you to verify, then mails the number, and it applies to the following filing season rather than the current one.
In person at a Taxpayer Assistance Center
Requires an appointment and two forms of identification. The fallback when online verification fails and Form 15227 does not apply.

The Annual Renewal Nobody Expects
The number changes every January, and last year's will reject your return.
An IP PIN is valid for one calendar year. The IRS generates a new one each year and makes it available in your Online Account in early January. Enrolled taxpayers also receive Notice CP01A by mail with that year's number.
The most common IP PIN failure
Someone enrolls, saves the number somewhere sensible, and uses it again the following year. The return rejects with an IP PIN mismatch, which looks alarming and is entirely routine. Pull the current year number from your Online Account and refile.Do not rely on the CP01A letter arriving. It goes to your address of record, which is whatever address was on your last filed return, and it is one of the more commonly lost pieces of IRS mail. The Online Account is authoritative and always current.
If You Are Already a Victim
The sequence matters, and an IP PIN is not the first step.
If your electronically filed return was rejected because a return already exists under your Social Security number, you are past prevention and into remediation. Confirmed victims are enrolled in the IP PIN program automatically once the case is resolved, so applying is not the immediate task.
1. File Form 14039, the Identity Theft Affidavit
This opens the case with the IRS Identity Theft Victim Assistance unit.
2. File your real return on paper
Electronic filing stays blocked while the duplicate exists. Your return is still due, and filing it protects your refund claim.
3. Pull a tax account transcript
It shows what the fraudulent return claimed, which is how you know what has to be unwound.
4. Expect a long resolution timeline
These cases historically take many months. Keep filing on time each year while it is open.
Step three is where the tax account transcript earns its keep, since it shows exactly what was filed and what was paid out. If the transcript instead shows assessments for years you never filed, that is usually a substitute for return rather than identity theft. And if a letter prompted all of this, check it against the CP14 balance due notice or the CP3219A notice of deficiency before responding, because the deadlines differ sharply between them.
Return Rejected Because One Was Already Filed?

Frequently Asked Questions
How do I get an IRS Identity Protection PIN?
The fastest route is the Get an IP PIN tool in your IRS Individual Online Account, which issues the number immediately after identity verification. If you cannot verify online and your income is under the published threshold, you can file Form 15227 and receive it by mail. In-person verification at a Taxpayer Assistance Center is the fallback.
Can anyone get an IP PIN, or only identity theft victims?
Anyone with a Social Security number or ITIN can voluntarily opt in. The program was originally limited to confirmed identity theft victims, but the IRS opened it to all taxpayers who can verify their identity. Confirmed victims are enrolled automatically and cannot opt out.
How long is an IP PIN valid?
An IP PIN is valid for one calendar year only. A new six digit number is generated each year, typically available in your IRS Online Account in early January. Using the prior year number on the current year return will cause the return to reject.
What happens if I lose my IP PIN?
Retrieve it through your IRS Individual Online Account, which shows the current year number immediately. If you cannot access the account, you can request a reissue by phone after identity verification, though that route mails the number and takes considerably longer.
Do I need to give my IP PIN to my tax preparer?
Yes, if you want the return to be accepted electronically. The number must be entered on the return itself. The IRS will never call, email, or text you asking for it, so any unsolicited request for your IP PIN is a scam regardless of how official it looks.
What is Notice CP01A?
Notice CP01A is the letter the IRS mails to enrolled taxpayers each year containing the IP PIN for that year. If you are enrolled and did not receive it, retrieve the number from your IRS Online Account rather than waiting for a replacement letter, because the mailing does not always reach people who have moved.
