If a dependent or qualifying person listed on your return has ever received an IP PIN (Identity Protection Pin), a CP01A notice, or opted into the IRS's IP PIN program, that person's special 6-digit IP PIN needs to be on the return to validate their identity for e-filing. The IRS provides participants a new IP PIN for each tax year.
An IP PIN and a Self-Select PIN are two different things.
An IP PIN is a 6-digit number that the IRS gives taxpayers who were victims of tax-related identity theft. Someone can also self-register to receive an IP PIN.
A Self-Select PIN is a random 5-digit number that you enter as your electronic signature when e-filing your return.
Find your dependent or qualifying person's 6-digit IP PIN
Look at the CP01A letter they received in December or January for their 2025 taxes. IP PINs from prior tax years won't work.
If they lost or never got a CP01A letter, retrieve their IP PIN online on the IRS Retrieve your Identity Protection PIN (IP PIN) page.
If unable to retrieve their IP PIN online, you can have it reissued (allow up to 21 days).
Once you have the PIN
On the Was anyone on this return assigned an Identity Protection PIN? screen, select Yes.
On the Add any Identity Protection PINs screen, select Add next to the person's name.
On the Add IP PIN screen, enter or correct the IP PIN and select Save.
Select Continue .
Select File in the menu.
On the Welcome back screen, select Continue.
Don't select Fix my return.
Select Start next to Step 3 to refile your return.
