IRS Notice CP22A: Tax Return Changes — Amount Now Due

IRS Notice CP22A informs you that changes were made to your tax return — either by the IRS or because you filed an amended return — and you now owe an additional amount as a result.

What CP22A Means

CP22A is a billing notice that follows a change to your filed tax return. The IRS sends this notice when:

• You filed an amended return (Form 1040-X) that increased your tax liability
• The IRS made corrections to your return (for example, fixing a mathematical error or adjusting a credit)
• You responded to a CP2000 underreporter inquiry and agreed to the proposed changes

The notice shows the specific changes made, the original tax liability, the revised tax liability, and the resulting balance due. CP22A means the IRS has already processed the change — this is not a proposal. It is an official billing notice for the newly assessed amount.

While the notice is informational in tone, the balance it reflects is real and will begin accruing interest and penalties if not paid.

Why You Received This Notice

CP22A is issued because:

• You filed Form 1040-X (amended return) and the changes resulted in additional tax owed
• The IRS corrected an error on your original return that increased your tax liability
• You agreed to IRS-proposed changes (from a CP2000 or examination) and the IRS has now formally assessed the agreed-upon amount
• An audit or examination concluded with changes that you did not contest

Key Deadline and Consequences of Ignoring

You have 21 days from the date on CP22A to pay the new balance. After that:

• Interest begins accruing on the unpaid balance at the federal short-term rate plus 3%
• The failure-to-pay penalty (0.5% per month) applies to unpaid balances
• The IRS will send follow-up collection notices (CP501, CP503) if the balance remains unpaid
• The standard IRS collection process — liens and levies — will eventually follow if ignored long enough

What to Do — Step by Step

1. Understand what changed. Read the notice carefully. It will explain which specific lines on your return were changed and why. Compare it to your original return and any amended return or CP2000 response you submitted.
2. Verify the changes are correct. If you filed an amended return, confirm the CP22A reflects the numbers on your 1040-X. If the IRS made the change, confirm their math is right.
3. Pay within 21 days if you agree. Pay online at IRS.gov/payments, by phone, or by mail. Paying in full immediately stops all further interest and penalty accumulation on this new balance.
4. Set up an installment agreement if you can’t pay in full. Use Form 9465 or the IRS Online Payment Agreement tool. For balances under $50,000, approval is often automatic if you are current on filing.
5. Dispute the change if you disagree. If you believe the IRS change was incorrect, contact the IRS at the number on the notice. Provide documentation supporting your original return. If the change came from an examination, you have the right to appeal through the IRS Office of Appeals.
6. Keep a copy of CP22A with your tax records. The notice number, tax year, and assessment date may be needed if you have questions later.

Your Rights

You have the right to:

• Review and verify all changes the IRS made to your return
• Challenge any change you believe is incorrect through the IRS appeals process
• Set up a payment plan if you cannot pay the new balance in full
• Request penalty abatement if the underpayment was due to reasonable cause
• Seek representation from a tax professional or Low Income Taxpayer Clinic (LITC) if you believe the changes are wrong
