What is a CP117 Notice?

The IRS issues a CP117 Notice when it detects suspicious activity, inconsistencies, or errors associated with a taxpayer’s account or tax return. The primary purpose of this notice is to inform the taxpayer that their account has been temporarily locked to prevent unauthorized use or further issues. The IRS may lock an account for various reasons, including suspected identity theft, discrepancies in reported income, or potential errors in filing.
The CP117 Notice details the reason for the account lock, such as mismatched information, suspicious returns, or other inconsistencies flagged by the IRS. It also includes instructions on how the taxpayer can resolve the problem. Addressing the notice promptly is essential, as failure to act can result in delays in processing returns, withholding of refunds, or further action by the IRS.

Why does the IRS issue a CP117 Notice?

The IRS aims to protect taxpayers from identity theft and ensure the accuracy of tax filings. Therefore, it may lock an account if it suspects any irregularities. Here are some common reasons why a CP117 Notice might be issued:

1. Identity theft concerns

If the IRS suspects that someone is attempting to file a fraudulent return using your Social Security number (SSN), it may issue a CP117 Notice. Locking the account helps prevent unauthorized individuals from claiming a tax refund or altering tax records.

2. Inaccurate or inconsistent tax information

If the IRS detects discrepancies between the tax return filed and the information it has on file (e.g., income reported by employers), it may flag the return and issue a CP117 Notice. This lock helps ensure that only legitimate and accurate returns are processed.

3. Unusual or suspicious filing activity

The IRS may detect unusual patterns in filing activity, such as multiple returns submitted for the same SSN, unusually high refund claims, or other red flags that trigger a review. In these cases, the IRS locks the account and sends a CP117 Notice to address the issue.

Pro Tip

Keep a copy of all correspondence and documents you send to the IRS. This documentation can help resolve disputes quickly and provide proof if needed.

How the CP117 Notice affects you

Receiving a CP117 Notice means the IRS has flagged your account, which may delay the processing of your tax return or the issuance of any refunds. The notice indicates that action is required to unlock the account. Here’s how it can impact you:
  • Delayed tax refunds: Your tax refund may be withheld until the issue is resolved.
  • Additional verification: You may need to verify your identity or provide additional documentation to the IRS.
  • Complications with future filings: If the issue is not resolved, future tax filings may be affected, potentially leading to further delays or penalties.

Steps to take when you receive a CP117 Notice

If you receive a CP117 Notice, it is crucial to act quickly. Here’s what you should do:

1. Carefully review the notice

Read the CP117 Notice thoroughly to understand why your account was locked. The notice should include details about the suspected issue and instructions on what steps to take next.

2. Verify your information

Double-check the information you submitted on your tax return to ensure accuracy. Make sure that your Social Security number, income figures, and other personal information match the records you have.

3. Contact the IRS

Reach out to the IRS using the contact information provided in the notice. The IRS representative can guide you on the next steps, such as verifying your identity or correcting any discrepancies.

4. Provide the requested documentation

The CP117 Notice may require you to submit specific documents to verify your identity or correct errors on your tax return. This may include a copy of a government-issued identification (e.g., driver’s license), your tax return, and any supporting documents.

5. Follow up as needed

After submitting the required information, follow up with the IRS to confirm that your account has been unlocked and that your tax return is being processed.

Pro Tip

Consider enrolling in the Identity Protection PIN program if you’ve been a victim of identity theft. This extra layer of security can help safeguard your tax account.

Alternative ways to handle a CP117 Notice

If you suspect identity theft, consider taking the following additional precautions:

1. Enroll in the IRS Identity Protection PIN program

The Identity Protection PIN (IP PIN) program provides an extra layer of security by assigning a unique, six-digit PIN to your tax account each year. This prevents others from filing a tax return using your Social Security number without the PIN.

2. Monitor your credit reports

Check your credit reports regularly for any suspicious activity that may indicate identity theft. This can help you catch any issues early and take action to protect your personal information.

3. File a police report if necessary

If you believe that your identity has been stolen, consider filing a report with your local police department. While this may not be necessary for all cases, it can provide additional documentation if you need to dispute fraudulent charges or activity.

What to do if the issue persists

If you have followed all instructions but the IRS has not resolved the issue, consider these steps:
  • Contact the IRS Taxpayer Advocate Service for assistance with your case.
  • Consult a certified tax professional for guidance on further action.
  • Visit a local IRS office to discuss the matter in person.

Pro Tip

Always respond to IRS notices within the deadline stated. Timely action can prevent further issues and ensure your tax return is processed without delay.

Potential penalties if you do not respond

Ignoring a CP117 Notice can lead to several consequences:
  • Your tax return may remain unprocessed, delaying any refund.
  • Additional penalties and interest may accrue on unpaid taxes.
  • Future tax filings could be impacted, leading to further complications.

Possible outcomes after responding to a CP117 Notice

Once you have addressed the CP117 Notice, here’s what may happen:
  • If your documentation is sufficient: The IRS will unlock your account, and your tax return will be processed as usual.
  • If discrepancies remain: The IRS may require further verification or adjustments to your tax return.
  • If identity theft is confirmed: Additional measures, such as an Identity Protection PIN, may be implemented to secure your account.
