What is a CP566 notice?

Mark Steber

Chief Tax Information Officer

Published on: June 22, 2020

IRS notices are letters sent to inform taxpayers of important tax information. Each one is different, but we can explain what the CP566 is about.

Understanding your CP566 notice

You applied for an Individual Taxpayer Identification Number (ITIN) and the IRS needs more information. Likely, your application is incomplete, or you sent the wrong accompanying documents.

Type of Notice

Request for information

Why you received the CP566 notice

You have received a CP566 notice because the IRS needs more information to process your ITIN application.

Likely next steps

As always, read the notice carefully and then review your application for an ITIN to ensure you answered all the questions correctly and provided the correct documentation. You will need to complete and sign the response form at the end of the CP566 notice and mail to the IRS with any accompany documents required for your application.

CP566 Notice deadline

You have 45 days from the date of the CP566 notice to reply with the appropriate information and/or documentation.

If you miss the deadline

The IRS will reject your application for ITIN and you will need to reapply.
