Identity Protection PINs for Families: A Planning Guide
Find out who needs a PIN, which year’s number to use, and how to coordinate before filing.
Identity Protection PINs for families work one person at a time. An IRS Identity Protection PIN (IP PIN) is a six-digit number tied to one person’s Social Security number or Individual Taxpayer Identification Number. Before you file, list who will appear on the return and check whether each person has a PIN.
Use the PIN for the calendar year you file. If you file a 2026 return in 2027, use the applicable 2027 PIN. The same principle applies when filing an older return. An IP PIN helps the IRS verify identity; it does not decide who can claim a child.
One person, one PIN
Check each spouse and dependent separately. There is no household PIN.
Use the current PIN
Check the year you submit the return, even when filing for a prior tax year.
Share securely
Use a verified preparer portal or another agreed secure method when the return is ready.
1. Check who needs an IP PIN on the return
| Person on the return | What to do |
|---|---|
| Primary taxpayer | Enter their current IP PIN if one was issued and applies, whether filing electronically or on paper. |
| Spouse on a joint return | Enter the spouse’s own current PIN if issued and applicable. If both spouses have one, enter both in the proper fields. |
| Dependent with an IP PIN | Enter that dependent’s current PIN when e-filing. The IRS says a dependent’s PIN is not required on a paper return. |
| Dependent who files their own return | If they have an applicable IP PIN, they use it as the taxpayer on their own return. A person claiming them also needs it for an eligible e-filed claim. |
Check each name and field before submitting. A missing or incorrect required PIN can cause an e-file rejection. An incorrect or missing taxpayer PIN on paper can delay processing.
2. Choose the right enrollment route
Adults who can verify their identity can use their own IRS Online Account or the IRS app. For voluntary online enrollment, the IRS describes a continuous option and an option that ends at the close of the current calendar year. Check the choice before enrolling. A one-time PIN obtained late in the year will not carry into the next filing year.
For a dependent under 18 or one unable to set up an IRS sign-in account, review the IRS dependent FAQ and Form 15227 instructions. Check the form’s eligibility and phone verification requirements. If that route is unavailable, schedule an appointment at a Taxpayer Assistance Center. Check which identification to bring for yourself and the dependent, and whether proof of guardianship is needed.
Start early if you need an appointment or mail delivery. If a PIN was already assigned, use the retrieval process instead of submitting another application.
3. Coordinate before filing when parents live apart
First determine who qualifies to claim the child and which benefits each parent may claim. Review the IRS rules for the tax year, including Form 8332 where applicable. A PIN does not transfer eligibility, replace a required release, or prove where the child lived.
If the child already has an IP PIN, plan how the eligible filer or their verified preparer will receive it securely when needed. Keep the number out of shared calendars, group texts, and custody worksheets. Do not share IRS passwords or one-time sign-in codes.
If your return is rejected because someone already claimed the dependent, verify the dependent’s information and your eligibility. For covered federal returns, a valid current IP PIN for the primary taxpayer can allow the second return to be e-filed despite the duplicate claim. Include the dependent’s PIN too if one was issued and is required. Acceptance does not resolve the competing claims.
Confirm the claim before arranging the PIN handoff
Two parents alternate claiming their child when the tax rules allow it. Before filing, the eligible parent checks whether a release is needed and confirms that the child has a current IP PIN. They arrange a secure handoff for that filing and record only “PIN confirmed” in their planning log.
4. Retrieve a missing PIN before you resubmit
Use IRS Online Account or the IRS app if available to the person who needs the PIN. If you can’t retrieve it online, follow the IRS reissue instructions. Phone assistance and mail reissue depend on identity verification and other IRS conditions. For a dependent, review the IRS recovery instructions before choosing another route.
Check the calendar year and whose PIN you entered. Correct the required field and resubmit if the return was rejected. Don’t remove an eligible dependent simply to bypass a PIN error.
5. Use this family filing checklist
- List everyone on the return and note who has an IP PIN.
- Confirm the PIN is current for the calendar year you will file.
- Check dependency eligibility and any required release separately.
- Confirm a secure way to provide each needed PIN.
- Save the e-file acceptance or rejection result and keep PINs out of the planning log.
Frequently asked questions
Is an IP PIN the same as an e-file signature PIN?
No. The IRS IP PIN helps verify identity and is separate from the PIN used to sign an electronic return.
Does every child need an IP PIN?
No. A parent or legal guardian can review voluntary enrollment. If the IRS already issued the child a PIN, follow the rules for including it when e-filing.
Can an IP PIN stop someone from claiming a child forever?
No. A PIN is a filing safeguard. Eligibility depends on the tax rules and facts for the year.
Make the PIN check part of your filing routine
Confirm who qualifies, check each required PIN for the year you file, and share it only through a secure channel when needed.
