Got an IRS CP22ANotice? Here's What It Means
Deadline & urgency
Disagreement windows on CP22A are limited. If you miss the response period, you may need costlier paths to reverse the change later.
What this notice means
CP22A means the IRS made changes to your return and you owe additional tax. The “A” series typically relates to adjustments with a balance due outcome.
The notice should show the revised figures and total amount due.
Why did I get this?
The IRS corrected items on your return—errors, mismatched documents, or disallowed claims—and the result increased your tax.
What should I do next?
Review each adjustment against your records.
If you agree, pay or arrange payment per the notice.
If you disagree, respond in writing by the deadline with evidence.
Frequently asked questions
CP22A vs CP11—what’s the difference?
Both communicate return changes and amounts due; the series and wording differ by IRS processing path. Treat both seriously and read your specific notice.
Do I need to amend?
Not always. Sometimes responding to the notice is enough; other times an amended return coordinates with the IRS adjustment—ask a pro if unsure.
Can penalties be removed?
You may request reasonable cause or first-time penalty relief if you qualify. Your notice lists what was charged.
