The CP66 notice is sent by the IRS to notify taxpayers that they are eligible for a refund based on their filed return; however, additional information or verification is required before the refund can be issued.
Key points about CP66:
- The notice specifies the amount of the refund due and outlines the reasons why further verification is necessary.
- Taxpayers are given instructions on what information or documentation they need to provide to expedite the processing of their refund.
- Failure to respond promptly may delay the issuance of the refund.
Taxpayers receiving CP66 should act quickly to provide the requested information to ensure their refund is processed without unnecessary delays.
