Summary:
IRS Notice CP72 is issued when the IRS believes that a taxpayer has filed a frivolous tax return. This notice comes with a hefty $5,000 penalty, and taxpayers may not initially know why they are being penalized. To dispute the penalty, taxpayers can file an appeal or, in some cases, pay the penalty and request a refund. Navigating this process can be complex, and failing to respond could result in significant financial consequences. In this article, we’ll explain what a CP72 notice is, how to respond, and what your options are for resolving the issue.
Receiving IRS Notice CP72 can be unsettling. This notice is issued when the IRS determines that your tax return contains frivolous information, meaning it does not meet the agency’s standards or follows established rules. What makes CP72 particularly concerning is that it comes with a substantial $5,000 penalty, and the IRS doesn’t have to provide the exact reasons for this determination upfront. You’re left to figure out what went wrong, often without immediate access to the necessary information. In this article, we’ll dive into what IRS Notice CP72 is, why it’s issued, and how you can appeal or resolve it.

What is IRS notice CP72?

IRS Notice CP72 informs taxpayers that the IRS has flagged their tax return as frivolous. According to the IRS, a frivolous return is one that either omits critical information or contains positions that do not have a basis in law, such as arguments against paying taxes entirely.
The notice is not to be taken lightly because, in addition to marking your return as invalid, it includes an automatic penalty of $5,000. You do not get a hearing or a trial before the penalty is assessed, making this a unilateral decision by the IRS. Unfortunately, the exact reason for the penalty is not always provided, leaving the taxpayer to investigate why their return was marked frivolous.

Why did I receive a CP72 notice?

There are several reasons why you might receive a CP72 notice. The IRS typically issues this notice if they believe your tax return contains frivolous information or claims that do not comply with tax law. Some examples include:
  • Arguments that taxes are unconstitutional.
  • Claims that income is not taxable under federal law.
  • Incomplete or misleading tax forms that omit required information.
The IRS does not tolerate positions or arguments that challenge the authority of the tax system. Filing such a return can trigger the CP72 notice and the associated $5,000 penalty. It is important to understand that the penalty applies automatically, and the IRS is not required to give you detailed reasoning behind their assessment upfront.

What should you do if you receive IRS notice CP72?

If you’ve received a CP72 notice, your first step should be to read the notice carefully. The IRS may not always specify which part of your return they find frivolous, so you will need to review your tax return and any supporting documentation to identify possible issues.
Here are the steps you should take:
  • Review your tax return: Check for any positions or claims that could be considered frivolous. If you are unsure, seek advice from a tax professional.
  • Consider amending your return: If you spot an error or believe the IRS has flagged your return incorrectly, you may want to file an amended return to correct any mistakes.
  • File an appeal: If you believe the CP72 notice was issued in error, you have the right to appeal the penalty through a Collection Due Process Appeal (CDP). This allows you to dispute the penalty and provide evidence to support your case.
  • Pay the penalty and request a refund: Another option is to pay the penalty and then file Form 843, Claim for Refund, to request a refund. If the IRS denies your claim, you may be able to take your case to U.S. District Court.

Pro Tip

Always respond to IRS notices by the deadline indicated on the notice to avoid additional penalties or enforcement actions. Request more time if needed, but never let the deadline pass without a response.

How to appeal a CP72 notice

Filing an appeal can be a complex process, but it is often the best route if you want to dispute the frivolous return penalty. Here’s how you can proceed:
  • Collection Due Process (CDP) Appeal: This type of appeal allows you to challenge the IRS’s determination before they take collection action. You’ll need to file Form 12153, Request for a Collection Due Process or Equivalent Hearing. In this appeal, you’ll present your case, arguing why your return was not frivolous.
  • Request a hearing: If the IRS grants your request, you will have a chance to present evidence that your tax return was valid and that the penalty was issued in error.
  • Provide compelling evidence: The IRS will not reverse its determination without strong evidence. You will need to gather documents or records that support the accuracy and legality of your return.
The IRS rarely reverses frivolous penalty determinations, so it is important to provide as much documentation as possible and potentially consult with a tax professional.

Paying the penalty and requesting a refund

If you want a faster resolution, you can pay the $5,000 penalty and then request a refund by filing Form 843, Claim for Refund. Here’s how you can do this:
  • Pay the penalty: You’ll need to pay the $5,000 frivolous return penalty in full (or a portion of it).
  • File Form 843: Once you’ve paid the penalty, submit Form 843 to the IRS, explaining why you believe the penalty was unwarranted and requesting a refund.
  • Sue the IRS if necessary: If the IRS does not act on your claim or denies the refund, you have the right to sue the IRS in U.S. District Court.

Pro Tip

Keep detailed records of all communications with the IRS, including copies of notices, letters, and any documentation you send. This will be crucial if you need to dispute the penalty or file an appeal.

How to avoid frivolous return penalties in the future

To avoid receiving another CP72 notice or facing frivolous return penalties in the future, follow these guidelines:
  • File accurate returns: Ensure that all the information on your tax return is accurate and complete.
  • Avoid unsubstantiated claims: Do not include positions that challenge the legality of taxes or make unsupported arguments that your income is not taxable.
  • Work with a professional: If you have complex tax issues, it is a good idea to work with a certified tax professional who can help you avoid errors.

Frequently asked questions

What should I do if I disagree with the CP72 penalty?

If you disagree with the CP72 penalty, the first step is to carefully review your tax return and the reasons why the IRS deemed it frivolous. You can file a Collection Due Process (CDP) Appeal by submitting Form 12153, where you can argue why the penalty is unwarranted. You will need to provide compelling evidence to support your case. If you are unsure how to proceed, consider consulting with a tax professional for guidance.

Can I request more time to respond to a CP72 notice?

Yes, you can request more time to respond to the CP72 notice by contacting the IRS using the phone number provided in the notice. It is important to act before the deadline indicated in the notice to avoid additional penalties or interest. If you are in the process of filing an appeal or gathering evidence, informing the IRS about your situation could prevent any further collection actions.

Is the $5,000 penalty for frivolous returns negotiable?

The $5,000 penalty for filing a frivolous return is generally non-negotiable unless you successfully dispute it through an appeal or court ruling. The IRS imposes this penalty automatically, but you may be able to reduce or remove it if you provide valid evidence that the return was not frivolous. In some cases, paying the penalty and then requesting a refund through Form 843 is an option.

What happens if I ignore the CP72 notice?

Ignoring the CP72 notice can lead to serious consequences. The IRS will assume that you agree with their assessment, and the $5,000 penalty will become final. The IRS may take further actions to collect the penalty, such as garnishing your wages or placing a lien on your property. Additionally, ignoring the notice could increase scrutiny on your future tax filings, making it more difficult to resolve any future issues.

Can I seek professional help to handle a CP72 notice?

Yes, seeking professional help is highly recommended if you are dealing with a CP72 notice. A certified tax resolution specialist, CPA, or tax attorney can help you understand why the notice was issued and advise you on the best course of action. They can assist in preparing an appeal, filing any necessary forms, and representing you in case of further disputes with the IRS.
