IRS Notice CP22A: Data-Match Adjustment
What it means
Your return was changed based on third-party data; balance may now be due.
What to do
Review the changes; pay or dispute.
Verify it's real. The IRS contacts you by mail first — never by phone, email, or text demanding payment. The notice includes a number in the top-right corner and instructions on irs.gov. When in doubt, log into your IRS online account rather than calling a number on the letter.
