An Identity Protection PIN (IP PIN) is a six-digit number issued by the IRS to help protect you from tax-related identity theft.
If the IRS issued you an IP PIN, you need to enter it on your tax return. The IRS uses this number to confirm that the return was filed by you—and not someone else using your information.
What does an IP PIN do?
Your IP PIN adds an extra layer of security to your tax return. It helps prevent someone from:
Filing a return using your Social Security number (SSN) or Individual Taxpayer Identification Number (ITIN)
Claiming your refund or tax credits fraudulently
Only you and the IRS know your IP PIN.
Who gets an IP PIN?
You may have an IP PIN if:
You were a victim of tax-related identity theft or the IRS identified you as a possible victim
You opted in to the IRS IP PIN program to protect yourself from identity theft.
Anyone with an SSN or ITIN can request an IP PIN, including people who live abroad.
If the IRS didn’t issue you an IP PIN, you don’t need one to file.
If the IRS issued you an IP PIN but you're not sure where to find it, see Where can I find my IP PIN?
What should I know about my IP PIN?
Your IP PIN is six digits
It’s issued by the IRS, not created by you
It changes every year
You must use the current-year IP PIN to e-file successfully
If you enter the wrong IP PIN—or skip it when one is required—the IRS may reject or delay your return.
