What a CP22A is
A CP22A is a balance-due notice reporting an adjustment the IRS made to your return. Three IRS sources describe it, and the two that add the useful detail are not the one most people find:
IRS: “We sent you this notice because we made the changes to your tax return. You owe because of the changes.” Taxpayer Advocate Service: “We made the changes you requested to your tax return for the tax year on the notice. You owe the IRS as a result of the changes.” and “You requested changes to your tax return for the tax year on your notice.” The IRS's published specimen, page 1: “Based on the information you provided, we changed your [year] Form 1040 to correct your: filing status ... total exemption amount.” — All read 6 September 2026
“Requested.” “Based on the information you provided.” In the ordinary case the sequence is: you filed an amended return, or answered a notice, or supplied a document; the IRS made the change; the change produced tax; this is the bill.
“Usually” is doing real work in that sentence and we are leaving it in. The CP22 series has other suffixes and adjustments can arise other ways. What the sources support is that a CP22A commonly follows information the taxpayer supplied — not that it always does.
What follows from it is the whole page. If you started this, the first thing to check is not whether the IRS is entitled to the money. It is whether the adjustment they made is the adjustment you asked for.
Your clock
Pay or respond by the date printed on the notice — and look in more than one place for it.
The IRS: “If you agree with the changes we made, pay the amount you owe by the date printed on your notice.”
A practical caution, drawn from the specimen the IRS itself publishes. That specimen prints a payment date in four places: in the Billing Summary, in the “what you need to do immediately” steps, on the payment stub, and again under “if we don't hear from you”. On the published sample, those dates are not all the same. The sample also carries a notice date in a different year from its due dates, which suggests it was assembled rather than issued — so this is a fact about the IRS's specimen, not a claim about your letter.
The safe practice it points to is simple and costs nothing: find every date printed on your notice, and work to the earliest.
Two other things about that specimen are worth knowing before you assume the worst about your own. The adjustment in it actually reduced the tax by $963 — the $24.60 left owing is the residue of an earlier balance, not new tax. And page 3 of it directs the reader to a web address for a different notice entirely. A CP22A is a document produced by a system, and systems produce artifacts. Read yours rather than the idea of it.
There is no 90-day window here and no Tax Court route, and that is not an oversight. A CP22A reports tax that has already been assessed. The stage that carries a Tax Court right — the notice of deficiency — comes before assessment, not after it. What that notice is, and why it matters that it comes first →

What triggered it
Something you sent produced a change, and the change produced tax. Common routes:
- An amended return, Form 1040-X, that reduced a credit, changed a filing status or added income.
- An answer to an earlier notice in which you supplied figures.
- A correction you asked for, where the correction had a consequence you had not priced.
- Information supplied by a preparer on your behalf.
The specimen's example is instructive because it is so ordinary: a filing status corrected to head of household, and an exemption amount adjusted with it. Nothing adversarial, and a balance at the end of it.
The check worth running. Compare what the notice says was changed against what you asked to be changed. Those are usually the same thing. Where they are not, that is the finding — and it is a finding about the IRS's processing rather than about your return.
What happens if you do nothing
Interest and a late-payment penalty accrue, and the account moves into the ordinary collection sequence.
The IRS's own FAQ on this notice: “Yes, interest will accrue if you don't pay the full amount you owe by the date on the payment coupon.” And on penalties: “Yes, you'll receive a late payment penalty.”
The notice itself is direct about what silence means. Its specimen reads: “We'll assume you agree with the information in this notice if we don't hear from you.”
From there it is the collection path, which starts with reminders and escalates. What the first collection notice looks like and what it means →
If the change described on the notice is not the change you asked for, the order of what you do next matters and paying first closes one of the doors. (800) 236-3741 · Book thirty minutes →
If you disagree — and what the notice does not tell you
The notice itself, the IRS's page for it and the Taxpayer Advocate Service's page all give a disagreeing reader the same instruction: call the number.
The specimen: “If you don't agree with the changes — Call 1-800-xxx-xxxx to review your account with a representative.” The IRS's page: “If you disagree with the changes we made, contact us at the number provided on your notice.” The Taxpayer Advocate Service: “If you disagree with the balance due in the notice, call the IRS at the toll-free number on the top right corner of your notice.”
That is not a criticism of the notice. The tax has been assessed, so there is no Tax Court right to publish and no Appeals conference attached to this letter. But it does mean that the routes which do exist are not on the document in your hand, and one of them is worth knowing about.
The route the IRS names on its own CP22A page, in a FAQ answer rather than in the instructions: “What if I need to make another correction to my account? You'll need to file Form 1040-X, Amended U.S. Individual Income Tax Return.” That is the published answer for a CP22A that adjusted something incorrectly, and it is not on the notice.
Audit reconsideration, where an examination is actually behind the notice. The IRS describes it as a process “to request a reevaluation of an audit assessment when your credits were disallowed, you disagree with the findings and the tax liability remains unpaid, or the IRS made a processing or computational error.” Read the scope carefully: it is about an audit assessment, and its own instructions begin with “Review your audit report, Form 4549.” A CP22A that followed an examination is within it. A CP22A that is simply the bill for your own amended return is probably not, and Form 1040-X is the route the IRS publishes for that one.
And the condition, which runs against every instinct:
“You can only request audit reconsideration if the assessed tax liability remains unpaid. If you've already paid the tax, you'll need to file an amended return (Form 1040X) to claim a refund.” — IRS, audit reconsideration guidance, read 6 September 2026
Paying the bill to make it stop is what closes that door. The refund route that remains has its own deadline, and it turns on dates specific to your account rather than on the notice in front of you — which makes it worth checking before you pay rather than after.
What reconsideration needs is new information. “The IRS focuses on information they haven't previously considered.” A request that repeats what was already sent goes nowhere. The written route is a letter setting out each disputed issue, or Form 12661, Disputed Issue Verification, with copies and the report if there is one. The IRS estimates 30 days to respond and says it “may take longer, potentially several months.”
There is also one thing the IRS does publish on its own CP22A page and almost nobody quotes:
“You can call us at the number listed on your notice if you're unable to pay the full amount shown because of circumstances beyond your control. If you contact us by the due date of your payment, we may be able to remove the penalty, depending on your situation.”
Note “may” and “depending” — this is not a guarantee. Note also “if you contact us by the due date of your payment.” The invitation has a date on it.
How much of this is penalty, and can any of it come off
The penalty that attaches to a number like this does not work the way most pages describe it, and the difference is in your favor.
You filed a return. The tax being proposed here was not shown on that return — so the late-payment penalty that applies is the one at 26 U.S.C. 6651(a)(3), and it does not run from the original due date. The statute starts it:
“within 21 calendar days from the date of notice and demand therefor (10 business days if the amount for which such notice and demand is made equals or exceeds $100,000)”
That is a genuinely useful fact and almost nobody publishes it. The failure-to-file penalty at 5% a month is the one every article leads with, and it does not apply to you at all — it attaches to a return that was not filed. Yours was.
| What runs | Rate | The condition that matters |
|---|---|---|
| Late payment on the assessed amount — 6651(a)(3) | 0.5% of the unpaid tax per month or part of a month, capped at 25% | Starts 21 days after notice and demand, not from the original due date |
| After a levy notice — 6651(d) | Doubles to 1% per month | For each month beginning after the day 10 days after the IRS issues its notice of intent to levy |
| During a payment plan — 6651(h) | Halves to 0.25% per month | For any month a plan is in effect, for an individual who filed that year's return by its due date or extension |
| Interest — 6601 | Runs separately | Not capped. The penalty stops at 25%; the interest does not stop |
Sources: 26 U.S.C. 6651(a)(1), 6651(a)(3), 6651(d)(1) and (d)(2), 6651(h), read 6 September 2026.
One of those is an action rather than a fact. Where the 0.25% rate applies, putting a payment plan in place halves the late-payment rate for every month it runs — and you can apply for one yourself, today, on the IRS's own site, without waiting for any of this to resolve.
And there is a change in penalty relief being widely misread. The IRS announced the Automatic Exemption from Penalty in IR-2026-83, 8 July 2026. It genuinely is automatic — no request. But it is phased in, and there are two dates rather than one: income tax returns from tax year 2025, quarterly returns such as Form 941 from 2026. It also carries a condition the announcements rarely mention: timely filing and payment for the three prior years.
So check two things on your notice — the year and the form. If the year is earlier, the automatic process does not reach it, and First Time Abate is still the route. It has its own clean-record conditions, it is not granted to everyone, and it has to be requested. Nobody applies it to your account because you were entitled to it.
That is the shape of penalty relief generally: real, conditional, and asked for rather than given. It is also the part of a balance with a defined route to removal — the tax underneath it has no equivalent, which is why the penalty column is worth reading before the total.
