CP01

A CP01 is a resolution letter: the IRS verified your identity theft claim, placed a protective indicator on your account, and will monitor it. It closes a chapter rather than opening one — no additional action is needed.

“We've confirmed what happened, marked your account, and we're watching it. Keep filing on time. You'll use an Identity Protection PIN on future returns — a six-digit number we'll send you fresh each year — and any return filed without it under your number won't be processed.”

This letter asks for nothing. The IP PIN it describes becomes part of every future filing — losing track of it is the only way this protection turns into friction.

• The notice, filed with your tax records
• Your annual IP PIN letters as they arrive each December or January
• Credit reports, worth monitoring after any identity event
• A request for a redacted copy of the fraudulent return, if you want to see what was filed

• Filing correctly with the IP PIN so returns aren't rejected
• Requesting the redacted fraudulent return on your behalf
• Untangling any residue the fraudulent filing left on the account
• Broader identity cleanup coordination — FTC, credit bureaus, state filings
