The CP01B means the IRS is processing your identity theft claim but needs additional information or documentation to continue. Your case is open and active, but it's stalled until you provide what they're requesting.
What the IRS Typically Needs
Common requests include a copy of your government-issued photo ID, a completed IRS Identity Theft Affidavit (Form 14039) if you haven't already submitted one, proof of your identity such as a Social Security card or birth certificate, copies of tax returns you actually filed to distinguish them from fraudulent filings, and documentation of any financial accounts opened fraudulently in your name.
The letter lists exactly what they need. Send everything requested, not just part of it. Partial responses create additional delays and generate follow-up requests.
The 30-Day Window
You typically have 30 days to respond. If you need more time, call the number on the notice and request an extension before the deadline passes. The IRS understands that gathering identity theft documentation can be difficult, especially if your records were compromised.
What Happens If You Don't Respond
If you don't respond, the IRS may close your identity theft case without resolution. That means the fraudulent return may remain on your account, your legitimate return may remain unprocessed, and your refund may stay frozen. Reopening a closed case is possible but adds months to the resolution timeline.
Keep Records
Identity theft cases can take 6 to 12 months to resolve. Keep copies of everything you send to the IRS, along with delivery confirmation. Note the dates of every phone call and the name or ID number of every IRS employee you speak with. This paper trail protects you if your case falls through the cracks.
