CP24 Notice
The CP24 is an IRS notice informing you that the IRS found a discrepancy between the estimated tax payments on your return and those posted to your account — in your favor. The IRS has determined you have a credit and will either issue a refund or apply it to other taxes owed.
Why Did You Receive This Notice?
You received a CP24 because the IRS found that you made more estimated tax payments than you claimed on your return. This can happen if a payment was posted to your account after you filed, if a prior-year overpayment was carried forward, or if the IRS corrected a processing issue that added a credit to your account. The IRS is notifying you of the resulting credit.
What Does this Mean for You?
The CP24 means the IRS adjusted your return in your favor and you have a credit. The notice shows the discrepancy they found, the adjusted credit amount, and what the IRS plans to do with it — either issue a refund check, send a direct deposit, or apply the credit to another outstanding tax balance you may owe.
What Happens If You Ignore It?
Your Options
- Review and confirm: If the credit amount looks correct, no action is needed. Your refund will be issued automatically by check or direct deposit.
- Dispute the amount upward: If you made additional estimated payments not reflected in the CP24, respond with your payment documentation before the statute of limitations expires for that tax year.
- Apply to another year: If you owe taxes from a prior or current year, the IRS may automatically apply this credit to reduce that balance rather than issuing a refund.
Step-By-Step: What To Do Next
Step 1: Read the CP24 carefully and note the tax year and the credit amount the IRS calculated.
Step 2: Compare the notice to your own payment records for that tax year.
Step 3: Log into your IRS Online Account to confirm the credit appears correctly on your account.
Step 4: If you agree, no further action is needed — your refund will arrive by mail or direct deposit within a few weeks.
Step 5: If you believe additional payments were not counted, gather documentation and call the IRS or respond in writing.Step 6: File the notice with your tax records.
Can You Handle this Yourself?
A CP24 generally requires minimal action on your part. Review the notice to confirm the math is correct and all your estimated payments were included. If everything looks right, simply wait for your refund. If you believe a payment was missed, pull your bank records and call the IRS — misapplied payments can usually be corrected with one call if you have documentation.
Expert Insight From Rockwater Tax
At Rockwater Tax, we always recommend reviewing a CP24 rather than just celebrating the refund. In some cases, the IRS will apply your credit to an outstanding balance from a prior year without notifying you in advance. If your refund is smaller than expected, check whether an offset was applied. Also confirm that all your estimated payments are included — it's possible you are owed even more than the notice reflects.
