Certifying Acceptance Agents will receive various notices that generate from the processing of Form W-7 applications. A general explanation of the notices follow:

Form 14433 – Return of Original Documents

This IRS Letter is used for the purpose of returning the applicant’s original supporting documentation. This Letter is bilingual, displaying both English and Spanish.

CP-565 Notice – Individual Taxpayer Identification Number (ITIN) Assignment Notice

This notice is issued to provide applicants with their assigned or renewed ITIN. Duplicate notices may be sent for various reasons (i.e. a requested name or address change, non-receipt of original assignment letter, etc.). The letter is for informational use only and does not have the same purpose as a Social Security card. IRS does not authorize nor does it endorse its use for any reason beyond tax purposes.

CP-566 – Individual Taxpayer Identification Number (ITIN) Suspense Notice.

This notice acknowledges the receipt of the application and provides an explanation of the reason it cannot be processed, usually as a result of a missing U.S. Federal income tax return or incomplete or missing information. Selective paragraphs identify the individual conditions that prevent Form W-7 processing.

If you receive a CP-566 notice for an application you submitted on behalf of a client, clearly and legibly write the information in the space provided on the notice and return it to the IRS. If you are providing a copy of the “originally” filed Form W-7 make sure to notate in capital letters across the top of the Form W-7, “COPY

– DO NOT PROCESS”. This will prevent the copy from being processed as a new or duplicate application since this could further delay processing.

Note: If you do not respond to this notice within the given time frame, your Form W-7 application may be rejected.

CP-567 – Individual Taxpayer Identification Number (ITIN) Reject Notice.

This notice states that the application has been rejected for the reason specified. Examples of these reasons include (but are not limited to):

  1. The applicant has a valid Social Security Number

(SSN) and does not qualify for an ITIN. 2. The applicant already has an assigned ITIN; 3. The Internal Revenue Service does not authorize the

person who submitted the application to act as an Acceptance Agent; 4. The Acceptance Agent has been removed from the

Acceptance Agent Program; 5. A Form W-7 has previously been received and is

currently being processed. If a valid U.S. Federal income tax return was attached to the Form W-7, the tax return will be processed separately under a temporary Internal Revenue Service Number (IRSN). The Agent/applicant will have to submit a new Form W-7 with attached documentation to begin the ITIN process again.
