What is a CP406 notice?

The CP406 Notice is issued by the IRS to inform taxpayers that they require additional information regarding their foreign assets. This notice often relates to compliance concerns about foreign bank accounts, property, investments, or financial interests held abroad. The IRS mandates that U.S. taxpayers disclose foreign assets to comply with FBAR and FATCA, and a CP406 Notice suggests that the IRS needs clarification or further details to verify these disclosures.

Reasons for receiving a CP406 notice

There are several reasons why you might receive a CP406 Notice:
  • Inaccurate or incomplete foreign asset reporting: The IRS may suspect that your foreign asset information is incorrect or incomplete, especially if they have received reports from foreign banks through FATCA.
  • Unreported foreign income: The IRS may want to verify that you have reported all income earned from foreign assets.
  • Potential tax discrepancies: If your tax return does not align with the information the IRS has about your foreign accounts, they may request further clarification.

Pro Tip

Consider consulting a tax professional experienced in international tax issues if you’re unsure about responding to the CP406 Notice. They can guide you through documentation requirements and help you avoid potential penalties.

How the CP406 notice affects you

The CP406 Notice signifies that the IRS is scrutinizing your foreign assets, potentially due to incomplete or missing information. This can lead to:
  • Additional compliance obligations: You may need to provide specific documents or clarify details to satisfy IRS requirements.
  • Risk of penalties: Non-compliance with foreign asset reporting can result in substantial fines and penalties, particularly if the IRS believes you intentionally avoided disclosure.
  • Delayed tax processing: Your tax return processing might be delayed until the IRS receives the required information.
If you act promptly to address the CP406 Notice, you can mitigate potential risks and streamline the review process.

What to do when you receive a CP406 notice

Receiving a CP406 Notice requires careful action to ensure full compliance. Here’s what you should do:
  • Read the notice thoroughly to understand what specific information the IRS is requesting.
  • Review your tax records and ensure that all foreign asset details were reported accurately, including account balances and sources of income.
  • Gather documentation, such as account statements or records of asset purchases, to support the information on your tax return.
  • Respond to the IRS by the specified deadline to avoid further action or penalties.

  • Failure to report foreign assets accurately may result in penalties under FATCA and FBAR regulations.
  • The IRS might impose additional fines or pursue further enforcement actions.
