IRS CP22A Notice: Changes to Your Return — Balance Due
A CP22A notice means the IRS made changes to your tax return — usually changes you requested, like an amended return being processed — and the result is a balance due of $5 or more.

What a CP22A actually means
A CP22A is the IRS closing the loop on a change to your return: an amended return (1040-X) you filed, a correction you asked for, or information you sent that changed the numbers. The notice shows the new balance after the change — tax, penalties, and interest.
The most important thing to check is whether the change matches what you actually requested. Processing errors happen: an amended return applied to the wrong year, a payment not credited, or a change you never asked for. If the change is right, this is simply a bill with the normal payment options; if it's wrong, respond before the collection sequence starts — a CP22A balance that sits unpaid escalates exactly like a CP14 does.
How to recognize a real CP22A
IRS accounts processing sends it after it changes an individual Form 1040 based on information you provided, and the account still shows a balance afterward. The IRS's sample CP22A points readers to irs.gov/cp21a for more information, so it belongs to the same family as the CP21 adjustment notices.
- The headline reads "Changes to your [year] Form 1040" with "Amount due" in large type underneath.
- A short bulleted list says what the IRS changed. In the IRS sample, those were the filing status (to head of household) and the total exemption amount.
- A Billing Summary starts from "Account balance before this change," then shows the increase or decrease in tax and interest, and ends with the amount due and its date.
- The box in the upper right shows the tax year, the notice date, a phone number, and a "Your caller ID" number to give when you call.
- A payment stub is attached at the bottom of page 1. For joint returns, the IRS sends a copy to each spouse and asks you to pay the amount only once.
What to do, step by step
- 1Compare the notice against the change you requested — pull your copy of the amended return or correspondence.
- 2Check that all your payments are reflected (your IRS online account shows what was credited, and to which year).
- 3If the change is correct and you can pay, pay by the due date at IRS.gov/payments to stop further interest.
- 4If you can't pay in full, set up an installment agreement — the balance is now assessed and eligible for a plan immediately.
- 5If the change is wrong or you never requested one, call the number on the notice and send documentation — don't just ignore a bill you disagree with, because it collects like any other.
Illustrative example
Example: tax went down, but a CP22A still says you owe
Luis (an illustrative taxpayer, not a real client) owed $1,180 on his original return and paid only part of it. Later he filed a 1040-X changing his filing status to head of household, which cut his tax by $960.
He was confused when a CP22A arrived showing "Amount due: $61.40." The Billing Summary explained it. The starting line was his unpaid balance before the change, and the amendment reduced it by the tax decrease plus the interest tied to it. That left a small remainder, because the change he asked for was smaller than what he already owed. The IRS's own sample CP22A works the same way: tax goes down and a balance is still due.
Luis checked that the changes listed matched his 1040-X and that his partial payment appeared in his online account. Then he paid the $61.40 through IRS Direct Pay before the due date. Had the numbers looked wrong, he would have called the number on the notice and given the caller ID printed in the header, because the notice says the IRS will assume you agree if it doesn't hear from you.

Mistakes that make a CP22A worse
- Assuming a CP22A means your amendment was rejected. It usually means the change was made and an older balance, or the interest on it, is still open. Read the Billing Summary from the top line down.
- Staying silent when you disagree. The notice says the IRS will assume you agree if it doesn't hear from you, so a wrong change becomes final by default.
- Paying twice on a joint return. Each spouse gets a copy, and the notice warns you to pay the amount due only once.
- Paying again right after a recent payment. If you paid or set up a payment plan in the past 21 days, the notice says to disregard it. Check your online account before sending more money.
What happens if you ignore a CP22A
If you don't pay by the date on the notice, penalties and interest keep growing on the balance and the IRS says it may take collection action. Because the notice treats silence as agreement, the change also stands as made.
Common questions
Why did I get a CP22A if I filed the amended return myself?+
That's the normal case — the CP22A is the receipt for the change. When an amended return increases your tax, the IRS assesses the difference and bills it with interest from the original due date. Verify the numbers match your 1040-X before paying.
What if I don't agree with the changes on my CP22A?+
Call the number on the notice with your return and records in hand, and follow up in writing with documentation. If the change didn't come from you, say so explicitly — account adjustments do occasionally land on the wrong taxpayer or the wrong year.
What happens if I don't pay a CP22A?+
It becomes ordinary tax debt: failure-to-pay penalties and interest accrue monthly, and the account moves into the standard collection sequence — reminders, then CP504, then a final notice of intent to levy. A payment plan set up now prevents all of that.
