Summary:
The IRS CP06 Notice tells you that your tax return is being audited to verify the Premium Tax Credit (PTC) you claimed. During this audit, the IRS might hold part or all of your refund until they confirm the accuracy of your claim. You need to respond within 30 days of receiving the notice by providing all required documentation. If you don’t respond, the IRS could adjust your return and issue additional taxes, penalties, and interest.
Finding out that your tax refund is on hold because of an IRS CP06 Notice can be concerning. This notice means the IRS is auditing your tax return to verify the Premium Tax Credit (PTC) you claimed. They might have identified discrepancies between your reported details and the data they received from the Health Insurance Marketplace. As a result, they require you to submit additional documents to confirm your eligibility. Until the audit is completed, your refund will remain on hold. Knowing how to respond and what steps to take can help minimize delays and ensure your refund is processed smoothly.

What is the IRS CP06 Notice and why did you receive it?

The IRS CP06 Notice is issued when your tax return is selected for an audit focused on verifying your Premium Tax Credit (PTC). This credit helps individuals and families afford health insurance bought through the Health Insurance Marketplace. The IRS audits these claims to ensure the PTC was accurately calculated and correctly claimed.
You might have received this notice for a few reasons:
  • A discrepancy between the information on your tax return and data reported to the IRS by other sources, like the Health Insurance Marketplace.
  • Your return may have been selected randomly as part of the IRS audit process.
  • There could be issues related to advance payments of the Premium Tax Credit (APTC).
Receiving a CP06 Notice doesn’t mean you made an error, but the IRS needs to verify the accuracy of your claim. However, if you fail to respond on time, the IRS may make adjustments to your return, which could lead to additional taxes and penalties.

Pro Tip

Submit your documents electronically through the IRS’s Campus Correspondence Exam Document Upload Tool. This method is the fastest and most secure way to provide the necessary information for your CP06 Notice audit.

How the IRS CP06 Notice affects your tax return and refund

When you get an IRS CP06 Notice, the IRS is holding part or all of your refund while they review your Premium Tax Credit (PTC) claim. This review ensures you claimed the correct amount and reconciled it with any advance payments of the credit.
Your refund will not be released until the IRS receives the required documentation and finishes the audit. This could delay your refund, depending on how quickly you submit the requested information and how long it takes the IRS to process it. If you don’t provide the necessary documents, the IRS may disallow your claim, which could lead to additional tax liability and a smaller refund.

Pro Tip

If you need more time to gather your documents, don’t hesitate to call the IRS at the number provided on the notice. Requesting an extension can help prevent automatic adjustments to your return.

Steps to take when you receive an IRS CP06 Notice

After receiving the IRS CP06 Notice, it’s essential to act quickly and provide the IRS with the documentation they requested. Here’s how to respond:

1. Review the notice carefully

First, read the IRS CP06 Notice thoroughly to understand why your Premium Tax Credit claim is being audited. The notice will list the documents you need to provide and the deadline for submission (usually 30 days).

2. Gather the required documentation

You’ll need to provide specific documents to support your PTC claim. The notice may include a list of required forms, such as:
  • Form 1095-A: This comes from the Health Insurance Marketplace and details your health coverage and any advance payments of the Premium Tax Credit (APTC).
  • Form 8962: Use this to reconcile the advance payments with the PTC you’re eligible for based on your income.
Make sure to review and complete Form 8962 to ensure the accuracy of your calculations.

3. Submit the documentation

You can submit your documents to the IRS in one of the following ways:
  • Upload them using the IRS’s Campus Correspondence Exam Document Upload Tool (Exam DUT).
  • Fax your completed forms to the number listed in the notice.
  • Mail copies of your documents to the address provided in the notice.
Make sure your documents are clear and complete to avoid delays. Don’t send original documents—only send copies.

4. Respond within the 30-day timeframe

You must respond within 30 days of the date on the IRS CP06 Notice. Failing to do so can result in the IRS making adjustments to your return, which could lead to additional taxes, penalties, and interest.

Consequences of not responding to the IRS CP06 Notice

If you don’t respond to the IRS CP06 Notice within the 30-day window, the IRS may issue a new audit report proposing changes to your tax return. These changes could include:
  • Disallowing your Premium Tax Credit (PTC) claim.
  • Imposing additional tax liability for the repayment of any advance payments of the PTC (APTC).
  • Applying penalties and interest to any additional tax owed.
The IRS will send you a report outlining these changes, but you’ll miss the opportunity to provide supporting documentation. To avoid this, it’s essential to respond promptly.

Pro Tip

Ensure that your Form 1095-A from the Health Insurance Marketplace is accurate before filing. Errors in this form often trigger CP06 Notices, so reviewing it ahead of time can help avoid unnecessary audits.

How to avoid future IRS audits related to Premium Tax Credits

To reduce the chances of receiving another IRS CP06 Notice, you need to ensure that your tax return is accurate, especially when claiming the Premium Tax Credit (PTC). Start by carefully reviewing your Form 1095-A, which is provided by the Health Insurance Marketplace, for any errors. Pay special attention to the amounts and personal details. Make sure the information on Form 1095-A matches what you report on Form 8962, which is used to reconcile any advance payments of the PTC. Discrepancies between these forms and your tax return can often trigger an audit.
Also, check that your reported income aligns with other documents, like W-2s or 1099s. Inconsistent information can raise red flags with the IRS. Filing your tax return electronically can also help reduce errors because the system is designed to catch common mistakes before submission. In addition, keep detailed records of your income and health insurance coverage. This way, if your return is questioned, you can quickly provide the necessary documentation to the IRS and resolve the issue.

Frequently asked questions

Why did the IRS audit your Premium Tax Credit claim?

The IRS may audit your Premium Tax Credit (PTC) claim for several reasons. These include discrepancies between the information on your tax return and what the Health Insurance Marketplace reported. Additionally, your return could be selected randomly, through computerized screening, or due to inconsistencies in your reported income. Receiving a CP06 Notice doesn’t mean you did anything wrong, but it does mean the IRS needs more information to verify your PTC claim.

What happens if you ignore the IRS CP06 notice?

Ignoring the IRS CP06 Notice can lead to serious consequences. The IRS may disallow your Premium Tax Credit (PTC) claim and adjust your tax return. This could result in you owing additional taxes, facing penalties, and being charged interest. To avoid these outcomes, it’s essential to respond within the 30-day timeframe and provide the requested documentation promptly.

Can you still get your refund while under audit?

No, the IRS will hold part or all of your refund until the audit is completed and they have verified your Premium Tax Credit (PTC) claim. Once you submit the necessary documentation and the IRS approves it, they will release your refund. The faster you respond to the CP06 Notice, the sooner your refund can be processed.

How long will the IRS take to process your documents?

The time the IRS takes to process your documents depends on how quickly you respond and the volume of audits they are managing. Typically, it takes several weeks for the IRS to review your submission. If they require additional information, the process may take longer. Submitting your documents electronically can help speed up the process.

What if the IRS disagrees with your PTC claim after the audit?

If the IRS disagrees with your Premium Tax Credit (PTC) claim after reviewing your documents, they will send you a letter explaining the proposed changes to your tax return. You have the right to appeal the decision or provide more documents if you believe their findings are incorrect. If you don’t appeal or submit additional information, the IRS will adjust your return, which could result in additional taxes owed, penalties, or a smaller refund.
