What This Notice Means

You asked the IRS to extend your child's adoption taxpayer identification number (ATIN) for 1 year. The IRS can't process that request yet. It needs more information from you first.

An ATIN is valid for 2 years. If you still don't have a Social Security number (SSN) for your child, you can request a 1-year extension. That's the request this notice is about.

What to Do

Complete Form 15100, Adoption Taxpayer Identification Number (ATIN) Extension Request. A copy comes with your notice. Send it back within 60 days. Your reply needs to include:

  • The reason you need an extension.
  • The reason you can't get an SSN for the child.
  • The status of your adoption.
  • Original signatures of the adoptive parents, or your child's SSN if you have received it.

How to Send Your Reply

The quickest way is the IRS Document Upload Tool. You can also fax your reply to the fax number printed in the notice, using a fax machine or an online fax service. If you use an online fax service, check its privacy and security policies before you send personal information.

Keep a copy of everything you send and note the date you sent it.

If You Don't Reply

The IRS can't extend the ATIN without the information it asked for. If no reply arrives, expect the extension request to be rejected. You would then have to start over with a new Form W-7A.

Once the Adoption Is Final

An ATIN is a temporary number. After the adoption is final, stop using the ATIN and get an SSN for your child from the Social Security Administration. If you already have the SSN, include it with your reply.
