Income mismatch & return changes
An audit-by-mail asking for documents: the IRS is examining a specific item on your return — most often the Earned Income Tax Credit, dependents, or education credits — and wants proof before it decides.
Don't sit on it
An audit-by-mail asking for documents: the IRS is examining a specific item on your return — most often the Earned Income Tax Credit, dependents, or education credits — and wants proof before it decides.
Why you got it: Credits with documentation rules (relationship and residency for children, school records, income records) get verified by mail at scale.
Not a bill and not a finding. Nothing has been decided; that's the point of the letter. But silence decides it against you: no documents, and the credit is removed by default.
Your first move: Read exactly which item and which documents are listed. Gather copies — never originals — that match the list item for item, and send them by the date on the letter.
Every clock runs from this date — not from the day the letter reached you.
Copies only, organized to match their list, with a cover sheet naming the notice and tax year.
Send what you have plus a note on what's coming — a partial file beats an empty one.
EITC documentation cases are the LITCs' home turf, and they're free if you qualify.
Mail or fax to the address/number on the letter; keep copies and proof of sending.
The IRS asks for documents by mail — never by a link in a text. A 'CP75 upload portal' text message is a phishing page.
The credit or deduction is disallowed, a balance is assessed (often with interest), and the case moves to deficiency notices — where you argue uphill instead of handing over proof.
