IRS CP23 notice: What it means and why you received it
The IRS sends a CP23 notice when it finds a discrepancy between the estimated tax payments you reported and the amount credited to your account. These payments can include quarterly estimates or amounts carried over from prior years. The notice details the changes made to your return and informs you of any balance due.
The IRS issues this notice due to errors in reporting estimated payments, misapplied payments, or clerical mistakes. If the IRS adjusts your return because of these discrepancies, you may owe additional taxes, penalties, or interest. In some cases, you might even receive a refund if the IRS finds an error in your favor.
Why did the IRS send you a CP23 notice?
You received a CP23 notice because the estimated tax payments listed on your return don’t match the IRS records. This could happen for several reasons:
– You entered the wrong estimated payment amount on your return.
– The IRS didn’t credit a payment to your account.
– IRS processing caused changes to your tax return, such as adjustments from prior years or additional penalties.
– Estimated payments were transferred incorrectly from a previous year.
– You entered the wrong estimated payment amount on your return.
– The IRS didn’t credit a payment to your account.
– IRS processing caused changes to your tax return, such as adjustments from prior years or additional penalties.
– Estimated payments were transferred incorrectly from a previous year.
Always review the notice carefully and compare it with your records to understand the exact nature of the discrepancy.
Pro Tip
Always keep detailed records of your estimated tax payments, including dates, amounts, and methods of payment. This makes it easier to verify discrepancies with the IRS and resolve any issues quickly.
What to do if you received the CP23 notice
After getting a CP23 notice, follow these steps to address the issue and avoid penalties or interest:
Review the CP23 notice carefully
Start by reading your CP23 notice thoroughly to understand the changes made by the IRS. The notice will break down the adjustments, show the amount you owe, and list any penalties or interest.
Compare the payments
Next, compare the estimated tax payments on the notice with your records. Ensure that all the quarterly payments for the year are accounted for. Also, check whether payments carried over from the prior year were correctly applied.
Verify payment application
If the IRS didn’t credit one of your payments, contact them immediately. This could happen if a payment was misapplied or entered incorrectly. Have your documentation ready, such as cancelled checks or bank statements, when you contact the IRS.
Take action if you agree with the CP23 notice
If you agree with the changes, pay the balance by the date listed to avoid further penalties and interest. You can pay online, mail a check, or set up a payment plan if you can’t pay in full. Update your tax return copy for your records, but don’t send an updated return to the IRS unless instructed to do so.
Take action if you disagree with the CP23 notice
If you disagree with the changes, contact the IRS within 60 days. Call the toll-free number or send a letter explaining the discrepancy, along with any documentation that supports your claim. Include a copy of the notice and any proof of payment.
Sometimes a quick phone call resolves the issue, especially if a payment was misapplied. More complex issues may take 30-60 days or longer to resolve.

Pro Tip
If you can’t pay the full amount owed after receiving a CP23 notice, set up a payment plan as soon as possible. This will help you avoid additional penalties and interest while giving you more time to settle your balance.
Best ways to make a payment to the IRS
If you agree with the amount owed on your CP23 notice, taking prompt action to settle your balance is crucial to avoid additional penalties or interest. The IRS offers several payment options, allowing you to choose the one that best suits your financial situation:
Pay online
The IRS Direct Pay system allows you to make payments directly from your bank account with no fees. It’s one of the most convenient and secure ways to pay your taxes. To use Direct Pay, simply visit the IRS website, enter your payment information, and schedule your payment. You can even set up notifications to receive payment confirmation emails. Paying online is often the fastest method, ensuring that your payment is credited to your account immediately, helping you avoid late fees and interest.
Mail a check or money order
If you prefer a more traditional method, you can mail a check or money order to the IRS. Make the payment payable to the “United States Treasury,” and be sure to include the payment coupon from your CP23 notice. Write your taxpayer identification number (such as your Social Security number), the tax year, and the form number (Form 1040) on your check to ensure proper processing. Use the mailing address provided on the notice, and send the payment early to account for any potential delays with mail processing. This method may take longer, but it remains a reliable option.
Set up a payment plan
If you’re unable to pay the full balance at once, you can set up a payment plan with the IRS. There are two main types of payment plans: short-term (120 days or less) and long-term (monthly installments). To request an installment agreement, you can apply online using the IRS Online Payment Agreement tool, or you can call the number listed on your CP23 notice. Setting up a payment plan allows you to spread your payments over time, reducing the financial strain. Keep in mind, interest and late penalties will still accrue until the balance is fully paid off, but setting up a payment plan helps avoid more severe collection actions, such as tax liens or levies.
Pay by credit or debit card
The IRS also accepts credit or debit card payments through authorized third-party payment processors. While this option incurs processing fees, it offers flexibility for those who prefer to use their card to manage their tax payment. You can make card payments online or over the phone using IRS-approved processors. If you choose this method, it’s important to understand that interest rates from your credit card company will apply, so factor in any additional costs.
Consider IRS payment relief options
In cases of severe financial hardship, the IRS offers payment relief options such as “Currently Not Collectible” status or an Offer in Compromise (OIC). These options are for taxpayers who genuinely cannot pay their tax debt in full or through installments. You will need to provide detailed financial information to the IRS to qualify for these relief programs. If approved, the IRS may temporarily delay collection efforts or settle your tax debt for less than the full amount owed. It’s recommended to consult a tax professional if you’re considering this route, as it involves a complex approval process.
Pro Tip
Contact the IRS within 60 days of receiving the CP23 notice if you disagree with the changes. A quick response increases your chances of having the issue resolved without a formal review or additional complications.
How to respond if you disagree with the IRS CP23 notice
If you disagree with the CP23 notice, act quickly. Call the toll-free number or send a letter to the address on the notice. Include a copy of the notice and supporting documents, such as payment records or bank statements. Responding within 60 days gives you the best chance to reverse the changes without needing additional documentation. Providing more information strengthens your case.
If the IRS doesn’t reverse the changes, your case may go to the Examination Department for further review. This process lets you present more evidence and gives you the right to appeal. If you miss the 60-day window, the changes become final. You’ll need to file a claim for a refund, typically within three years of filing your return or two years from your last payment.
Possible outcomes after responding to a CP23 notice
Once you respond to the notice, a few outcomes are possible. If the IRS accepts your evidence, they’ll reverse the adjustments, reducing or eliminating taxes, penalties, or interest. You might also receive a refund if you overpaid. If the IRS doesn’t agree with your claim, the case will move to the Examination Department for formal review, where you can appeal.
If the IRS upholds their findings, you can still set up a payment plan. Ignoring the notice or missing the deadline leads to more penalties and interest, increasing the amount owed until resolved.

Frequently asked questions
I don’t pay estimated taxes. Why did I get this notice?
If you received a CP23 notice but did not make estimated tax payments, the most likely cause is an incorrect entry on the estimated tax line of your return. Double-check the amount you entered on your return and contact the IRS for clarification.
What should I do if a payment is missing?
If the IRS has not credited a payment you made, call the number listed on your CP23 notice. Be prepared to provide documentation, such as cancelled checks or confirmation of online payments, to resolve the issue.
What is an estimated tax penalty?
The IRS may assess an estimated tax penalty if you did not pay enough tax throughout the year through withholding or estimated tax payments. You can read more about this in IRS Publication 505, Tax Withholding and Estimated Tax.
Can I receive a penalty if I cannot pay the full amount?
Yes, if you cannot pay the full amount by the due date, you may be subject to a late payment penalty and interest. However, if you enter into a payment plan with the IRS, some penalties may be reduced as long as you keep up with your payment schedule.
Do I have to pay interest on the amount owed?
Yes, the IRS is required by law to charge interest on any unpaid tax balance until it is paid in full. The interest rate is adjusted quarterly and will continue to accrue until your account is settled.
