IRS IP PIN Rejection Help Center

How do you fix an IP PIN rejection?

Identify whose Identity Protection PIN is required, retrieve that person’s current six-digit IRS IP PIN, enter it in the correct software field and resubmit. Check the new filing acknowledgment to confirm acceptance. A guessed number or a PIN assigned to a different person will not resolve the issue.

The IRS’s IND-181-01 instructions identify an invalid primary-taxpayer IP PIN. Read the complete message before changing any information; a spouse or dependent can have a separate PIN requirement.

1. Make sure it is an Identity Protection PIN

An IP PIN is issued by the IRS to protect a taxpayer’s identity. It is different from the PIN used to sign an electronic return, and it is not your adjusted gross income (AGI).

Follow your software’s distinct prompts for identity protection and the electronic signature. The IRS electronic-return validation guidance explains how an assigned IP PIN can validate identity instead of prior-year AGI or a prior-year self-select PIN. Do not type an AGI amount into an IP PIN field.

If the rejection concerns AGI rather than an IP PIN, use our AGI rejection guide. Keep the full error message so your preparer can identify the correct issue.

2. Match the requirement to the right person

• Primary taxpayer: IND-181-01 concerns the primary taxpayer’s IP PIN. Check the number entered for that person.
• Spouse: IND-183-01 concerns the spouse’s IP PIN. Enter the spouse’s own number in their designated field.
• Dependent: identify the dependent named in the software’s message and review that dependent’s IP PIN entry. A parent’s number is not a substitute.

The IRS CP01A instructions say an electronic return must include the assigned IP PIN for each affected taxpayer, spouse or dependent. If only one spouse has an IP PIN, associate it with that spouse’s SSN. If both have one, each must use their own.

For a dependent with an assigned IP PIN, the IRS also requires the PIN on applicable e-filed Form 2441 and Schedule EIC entries. Follow your software’s instructions for carrying the dependent’s information to those forms.

3. Use the PIN for the year you actually file

When filing during 2026, use the 2026 IP PIN—even for a 2025 or older tax return. An IP PIN lasts for one calendar year; a new number is issued each year. The tax year printed on the return and the calendar year of transmission are different things. See the IRS IP PIN program guidance.

Check the year on your notice or retrieve the current number. Do not reuse an older saved PIN simply because you are filing an older return.

4. Retrieve a lost or missing IP PIN

If you can access your IRS account

Retrieve your current PIN under the profile section of your IRS Online Account through the official recovery page. New users must verify their identity.

If you cannot retrieve it online

U.S. callers can contact the IRS at 800-908-4490. After identity verification, eligible reissues go to the address on IRS records, with mailing described as within 21 days.

For a minor under 18: call the IRS to recover a lost or unreceived PIN; online retrieval is unavailable.

Form 15227 is for new enrollment, not replacement. First-time enrollment during the current year and annual maintenance can limit mail reissue. Check current recovery instructions.

If you have never been assigned an IP PIN

Start with the IRS enrollment instructions. Online enrollment requires identity verification. Form 15227 and an in-person Taxpayer Assistance Center appointment are alternatives, subject to the IRS’s eligibility and documentation rules. Alternative enrollment can take longer; it is not a way to bypass identity verification.

5. Review the entry and resubmit

1. Check the person identified in the rejection against the software field you are editing.
2. Compare all six digits with the current IRS-issued number, including any leading zero.
3. Review any separate spouse or dependent requirement before transmitting again.
4. Save the new acknowledgment and confirm whether the federal return was accepted. Submission alone is not acceptance.

If the same rejection returns after a verified entry, ask the software provider or preparer to review the transmitted fields and the exact code. Keep a record of the original rejection and each correction. RefundIQ can help you understand what to check, but only the IRS can issue or recover the IRS IP PIN.

Can you file a paper return without an IP PIN?

When online recovery and mail reissue are unavailable, the IRS recovery guidance describes filing a paper return without the missing IP PIN. The IRS will verify identity, which can delay processing and a refund. This is not a faster-recovery promise.

If you have the required primary-taxpayer or spouse IP PIN, enter it in the designated signature-area box according to the CP01A paper-return instructions. The IRS IP PIN FAQ says a dependent’s IP PIN is not required on a paper return. Follow all other signing, attachment and mailing requirements for the return you are filing.

What if the dependent was already claimed?

That is a different issue from a missing IP PIN. For tax year 2024 and later, the IRS allows an electronic filing route for duplicate-dependent rejections on Forms 1040, 1040-NR and 1040-SS using a valid IP PIN for the primary taxpayer. A new dependent IP PIN is not needed solely for this route, although an already-assigned dependent PIN must still be included.

This option does not decide who is entitled to the dependent. See IRS FAQ question 6 and our dependent-rejection guide for eligibility checks and filing options.

Keep your IP PIN private

Use a secure process to share it with your trusted preparer when needed for filing. The IRS warns about calls, emails or texts seeking your IP PIN. Keep PINs, SSNs and tax documents out of general website messages.

When contacting RefundIQ, start with the tax year, reject code and whether the error names you, your spouse or a dependent.

SSN already used or an IRS identity-theft notice?

Use the SSN already used hub for an unexplained earlier filing. If the IRS sent CP01 or CP01A, see what those notices mean before choosing an IP PIN or reporting step.

A letter asking you to verify a return requires a separate response from IP PIN enrollment or recovery. Use the IRS verification-letter guide to identify that route.
