The IRS Identity Protection PIN (IP PIN) is a six-digit number assigned to eligible taxpayers to prevent identity theft on their federal tax accounts. It verifies your identity when filing taxes and stops someone else from using your Social Security number to file a fraudulent return.
Each IP PIN is unique to a taxpayer and valid for one calendar year. It must be entered during e-filing or when using tax preparation software. The IRS issues it only after confirming your identity through prior tax returns or verified documentation.
Without a valid IP PIN, the IRS may reject your electronic return or delay processing. This measure protects millions of taxpayers annually from refund theft and account tampering.
The IP PIN acts as a second layer of authentication. When you file electronically, the IRS checks the IP PIN against your Social Security number and tax history. If they match, the return proceeds. If not, the system flags it for review.
For example, if someone uses your SSN to file a return claiming a refund, the IRS will detect the mismatch between the SSN and the incorrect IP PIN. The return gets rejected, and the fraud is blocked before funds are disbursed.
This system reduced identity theft refund fraud by 64% between 2016 and 2022, according to the IRS's 2023 Identity Theft Report. The agency reported that over 12 million IP PINs were issued in 2022 alone.
You must have filed a U.S. federal tax return in at least one of the past two years to qualify. The IRS automatically sends the IP PIN to those who previously reported identity theft or were flagged in the IRS Identity Theft Data Base.
To request one manually, visit the IRS website and use the "Get an IP PIN" tool. You'll need your SSN, date of birth, and the last four digits of your SSN. The system cross-checks your information against prior returns.
If you're not automatically enrolled, you can still apply. The IRS processes requests within 72 hours. Once approved, you receive the IP PIN via mail within 10 business days. Do not share it with anyone-not even tax preparers.
| Eligibility Requirement | Details |
|---|---|
| Filing History | Must have filed a tax return in 2021 or 2022 |
| SSN Verification | SSN must match IRS records exactly |
| Identity Confirmation | Answer security questions based on past returns |
| Processing Time | Online request: 72 hours; Mail delivery: 10 business days |
Many people confuse the IP PIN with the IRS PIN used for online login. The IP PIN is only for tax filing. The IRS login PIN is separate and used for accessing your online account.
Another error is assuming the IP PIN is permanent. It expires each year and must be renewed. In 2023, over 1.8 million taxpayers failed to update their IP PIN, leading to delayed refunds or rejection notices.
A lesser-known fact: the IRS does not issue IP PINs to individuals who haven't filed a return in the past two years-even if they've been victims of identity theft. You must have a prior return on record to qualify.
In 2022, a taxpayer named Maria used her 2021 return to apply for an IP PIN. She entered her SSN, DOB, and last four digits correctly. The system confirmed her eligibility and generated a new IP PIN.
She then used the PIN to file her 2022 return electronically. The IRS accepted it immediately. Without the IP PIN, her return would have been flagged due to a mismatch in SSN data.
When she checked her status five days later, the IRS showed "Return Accepted." Her refund was deposited in 14 days. This outcome reflects the success rate of IP PIN users: 97% of filings with valid IP PINs are processed without delay.
If you're denied access to the IP PIN portal, verify your SSN and DOB with the Social Security Administration. Discrepancies in name spelling or address history often cause rejection.
If you're a victim of identity theft, contact the IRS Identity Theft Hotline at 1-800-908-4490. You can also submit Form 14039, Identity Theft Affidavit, to report misuse.
Some taxpayers mistakenly believe they need to pay for the IP PIN. The IRS offers it free of charge. Any site charging for it is not official.
Once you have your IP PIN, store it securely. Share it only with your tax preparer if you authorize them to file under your name. Never send it via email or text.
