Your IRS e-file keeps getting rejected because you can’t find your IP PIN (and the retrieval tool went offline into January 2026)

The problem (and who it hits)

When the IP PIN is missing or incorrect:

• The IRS can reject your electronic return.


• A paper return may be accepted but can be delayed while the IRS verifies identity.

This problem hits:

• People who received an IP PIN in prior years and forgot they must use it again.


• Anyone who opted in online and now must retrieve the new IP PIN each year.


• Families where a dependent has an IP PIN (the dependent’s PIN may be required on your return).

Why it’s happening

1) IP PINs are required once you’re enrolled or assigned. The IRS uses the IP PIN to verify the taxpayer’s identity when a return is filed. If you’re assigned an IP PIN, you generally must include it when you file covered federal returns. [2]

2) The IP PIN changes each year. An IP PIN is valid for one calendar year, and a new one is generated annually. Some people get it by mail, while others must log in to retrieve it. [3]

3) The online IP PIN retrieval tool can be temporarily unavailable. The IRS states the IP PIN service in the Individual Online Account is unavailable during an annual maintenance period—specifically Nov. 16, 2025 through January 2026—which is exactly when many people start gathering tax documents and doing early filing prep. [1]

Solutions (step-by-step)

Solution 1: Retrieve your current IP PIN from your IRS Online Account (best option when available)

Notes:

• If you opted in online, you may not receive a mailed CP01A notice; you may need to retrieve the IP PIN online each year. [4]

Solution 2: Check for the CP01A notice (mailed or in your online notices)

1. Search your tax records for the CP01A notice (often arrives mid-December through early January).
2. If you use IRS Online Account notices, sign in and look for CP01A in your notices area.
3. If you find it, copy the 6-digit number exactly into your tax software.

Important: CP01A recipients generally don’t need to file identity-theft paperwork (Form 14039) unless a new identity theft incident occurs after receiving the notice. [2]

Solution 3: If you can’t retrieve it online, request a reissue by phone

1. Call the IRS IP PIN line: 800-908-4490 (Mon–Fri, 7 a.m. to 7 p.m. local time; Alaska/Hawaii follow Pacific Time). [1]
2. Be prepared to verify your identity.
3. If verified, the IRS says the IP PIN will be mailed within 21 days to the address on file. [1]

If you’re outside the U.S., the IRS lists an international number: 267-941-1000 (not toll-free). [1]

Solution 4: If you can’t get your IP PIN in time, decide between “wait to e-file” vs “paper-file”

• Option A (usually best): wait until you retrieve the IP PIN and then e-file correctly. This reduces the chance of refund delays.
• Option B: paper-file without the IP PIN only if you can’t access/reissue it. The IRS warns paper filing without the IP PIN can lead to identity verification review and refund delays. [1]

Solution 5: Don’t forget dependents and spouses who have their own IP PIN

1. Confirm who in the household has an IP PIN (you, spouse, any dependents).
2. Make sure each person’s IP PIN is entered with the correct taxpayer details.
3. If a dependent’s IP PIN is missing, treat it like the main issue: retrieve or reissue it.

The IRS provides specific guidance that dependents’ IP PINs may need to be included when you claim them. [4]
