The IRS CP178 Notice is a formal notification that you may need to file a final excise tax return, often Form 720, after four consecutive quarters of not owing any excise taxes. This notice suggests that you may no longer have excise tax obligations. The IRS provides specific instructions on filing a final Form 720 and how to notify them if excise taxes are no longer applicable to your business. This article will walk you through what the CP178 notice entails, what actions you should take, and how to handle this situation effectively.
Receiving any notice from the IRS can be stressful, especially when it concerns your business taxes. One such notice is the IRS CP178, which informs business owners that they may no longer owe excise taxes and may need to file a final Form 720. If you’ve filed zero excise tax liability for the last four quarters, the IRS issues this notice to confirm your tax status and guide you in finalizing your excise tax filings. Understanding the steps you need to take after receiving the CP178 notice is crucial in ensuring compliance and avoiding any unnecessary complications with the IRS.

What is a CP178 IRS notice?

The CP178 notice is issued by the IRS to inform a business or taxpayer that they may no longer owe excise taxes and might need to file a final excise tax return using Form 720. This notice is typically sent to businesses that have indicated for the last four quarters on their Form 720 that no excise taxes are due. Essentially, the IRS is checking if you still have any excise tax obligations or if it’s time to finalize your tax filings in this area.

What is Form 720?

Form 720 is a Quarterly Federal Excise Tax Return, which businesses use to report and pay excise taxes to the IRS. These taxes apply to specific goods and services, such as fuel, air transportation, and some health-related services. If a business no longer engages in activities that incur excise taxes, it will no longer need to file this form regularly. However, the IRS requires a final submission to close out the account formally, which is where the CP178 notice comes in.

Pro Tip

Set up IRS account alerts online to get real-time notifications on any changes to your tax return or account. This helps you stay updated on adjustments and due dates.

Why did you receive the CP178 notice?

The IRS sends a CP178 notice when your quarterly Form 720 reports indicate no excise tax due for four consecutive quarters. The notice prompts you to file a final Form 720, officially closing out your excise tax obligations. This process is a way for the IRS to confirm that your business has either ceased the activities that incur excise taxes or that you no longer need to file Form 720 moving forward.

Trigger for the CP178 notice:

  • No excise tax owed: Your business has reported zero excise tax liabilities on Form 720 for four quarters.
  • IRS follow-up: The IRS is checking whether your business still owes excise taxes or if it’s time to close your account.

How does the CP178 notice affect you?

Receiving the CP178 notice signals a significant moment for your business, as it indicates that your excise tax obligations may be coming to an end. You will need to decide whether to file a final Form 720 or continue filing quarterly excise tax returns if your business resumes activities subject to excise taxes.

Potential scenarios:

  • You no longer owe excise taxes: If your business no longer deals with goods or services that incur excise taxes, you can file a final Form 720 and close your excise tax account with the IRS.
  • You still owe excise taxes: If your business resumes activities that incur excise taxes, you will continue to file Form 720 as needed.

Pro Tip

If you no longer owe excise taxes, file your final Form 720 promptly to avoid unnecessary IRS notices or follow-ups in the future.

What you need to do

If you determine that you no longer owe excise taxes, the next step is to file a final Quarterly Excise Tax Return (Form 720). Here’s what you need to do:
  • Write “Not liable” at the top of your next Form 720.
  • Check the box labeled “Final return” on Page 1 of Form 720 in the upper left corner.
This will inform the IRS that you no longer owe excise taxes and that this is your final submission of the form. If, in the future, your business owes excise taxes again, the IRS will automatically send you Form 720 once you report excise tax due.

What are your options?

Once you receive the CP178 notice, you have a few options to consider based on your business’s current activities and excise tax obligations. These include filing a final return, continuing to monitor your excise tax liabilities, or consulting a tax professional for guidance.

Option 1: Filing a final return

If your business no longer owes excise taxes, filing a final Form 720 will close out your excise tax account. This is a straightforward process and ensures that the IRS no longer expects quarterly excise tax filings from your business.

Option 2: Continue filing if necessary

If your business anticipates owing excise taxes in the future, you will continue filing Form 720 each quarter. There’s no need to file a final return in this case, and you can continue your regular tax obligations without interruption.

Option 3: Consult a tax professional

If you’re uncertain about your excise tax obligations, it’s wise to consult a Certified Tax Resolution Specialist or a tax attorney. These professionals can help you navigate the complexities of excise tax law and ensure that you comply with all IRS requirements. They can also assist you if the notice was issued in error.

What happens if you don’t respond to CP178?

Ignoring the CP178 notice can result in complications with the IRS. While this notice doesn’t typically carry immediate penalties, failing to file a final Form 720 could lead to confusion or further inquiries from the IRS.

Potential consequences:

  • Continued IRS notices regarding your excise tax obligations.
  • Potential penalties if the IRS determines that you owe taxes but haven’t filed.
  • Delays in resolving your excise tax account status.
It’s always best to respond promptly and take the necessary steps to close your excise tax account if applicable.

Pro Tip

Always keep copies of your past Form 720 filings and any correspondence with the IRS for your records, in case of future inquiries or audits.

What should you do if the notice is sent in error?

In some cases, the IRS may issue a CP178 notice in error, especially if there’s a misunderstanding about your business’s excise tax activities. If you believe this notice was sent to you incorrectly, here’s what to do:
  • Contact the IRS directly using the phone number provided on the notice.
  • Review your past Form 720 filings to ensure they were completed accurately.
  • Provide any necessary documentation to clarify your tax status with the IRS.

Frequently asked questions

What is IRS Form 720, and why is it important?

Form 720 is the Quarterly Federal Excise Tax Return, which businesses file to report excise taxes on specific goods and services, such as fuel, air transportation, or certain health-related services. Filing this form ensures that businesses meet their federal excise tax obligations. If a business no longer incurs excise tax, filing a final Form 720 is necessary to close the excise tax account.

Do I need to file a final Form 720 if I don’t owe excise tax anymore?

Yes, if you have received the CP178 notice indicating that you no longer owe excise taxes, you should file a final Form 720. On this form, write “Not liable” at the top and check the “Final return” box. This action formally notifies the IRS that your business no longer incurs excise tax liabilities, preventing future filings.

What happens if I don’t respond to the CP178 notice?

If you ignore the CP178 notice, the IRS may continue to send notices requesting your Form 720 filings. Although this notice doesn’t initially carry penalties, failing to respond could lead to further inquiries or confusion about your business’s excise tax status. It’s best to resolve the issue by filing a final return if excise taxes are no longer applicable.

Can I file Form 720 electronically, and how do I indicate it’s my final return?

Yes, you can file Form 720 electronically through the IRS’s e-file system. When filing electronically, make sure to check the “Final return” box on the form and indicate that you are not liable for excise tax by writing “Not liable” in the appropriate section. This ensures that the IRS processes your final filing correctly.

What should I do if the CP178 notice was sent in error?

If you believe the CP178 notice was sent to you in error, contact the IRS using the phone number provided in the notice. Review your previous Form 720 filings to ensure that they were accurate.
