ATIN Questions and Answers

Q.1. What is an ATIN?

A.1. An ATIN is an Adoption Taxpayer Identification Number issued by the Internal Revenue Service as a temporary taxpayer identification number for the child in a domestic adoption where the adopting taxpayers do not have and/or are unable to obtain the child's Social Security Number (SSN). The ATIN is to be used by the adopting taxpayers on their Federal Income Tax return to identify the child while final domestic adoption is pending.

ATIN Questions and Answers

Q.3. Why do I need an ATIN?

A.3. Recent tax law changes require that when you list a person's name on your federal income tax return, you must provide a valid identifying number for that person. During the adoption process, you may not have been able to obtain an existing or a new Social Security Number (SSN) for the child who may already have been placed in your home. If you are eligible to claim the child as your dependent, and you don't have the child's SSN, then you will need to request an ATIN in order to claim the child as a dependent and ( if eligible) to claim the child care credit.

Q.9. What is placement documentation?

A.9. Placement documentation is the signed documentation placing the child in your care for legal adoption. In general, one of the following documents will satisfy this requirement:

  • A placement agreement entered into between you and a public or private adoption agency.
  • A document signed by a hospital official authorizing the release of a newborn child to you for legal adoption.
  • A court order or other court document ordering or approving the placement of a child with you for legal adoption.
  • An affidavit signed by an attorney, a government official, etc., placing the child with you pursuant to the states' legal adoption laws.

The placement documentation is sometimes referred to as "Placement Agreement"; "Surrender Papers"; "Temporary Placement Paperwork"; "Placement Order" etc. This documentation termed differently from state to state must clearly establish that the child was placed in your home for purposes of adoption by an authorized adoption agency (or agent), and must include the following information:

  • Adoptive Parent(s) full name
  • Child's full name
  • Name of the Placement Agency or Agent
  • The date the child was placed in the adoptive parents home.
  • The signature of the parent or parents (the adopting taxpayers) and that of an official representative of the authorized placing agency or agent.

ATIN Questions and Answers

Q.11. How long is the ATIN valid?

A.11. As soon as the adoption becomes final, the adopting parents should obtain an SSN for the child and notify the IRS of the new SSN. When the IRS is notified of a new SSN for the adopted child, it will deactivate the ATIN. If the adopting parents do not notify the IRS within two years, the ATIN will be automatically deactivated.

ATIN Questions and Answers

Q.12. Why does the ATIN deactivate after two years?

A.12. The automatic deactivation of the ATIN after a two year period is necessary because the ATIN is an identification number issued for temporary use until a valid SSN can be obtained for the adopted child. It is not a permanent valid identification number. A reminder notice will be sent eighteen months after the taxpayers receives the ATIN, informing the adopting parents, that the ATIN will expire in 6 months.

Q.13. What can I do if the ATIN expires before the adoption is finalized?

ATIN Questions and Answers

Q.16. Can I use an ATIN to claim the Earned Income Tax Credit?

A.16. No. You can only use an SSN to claim the EITC. However, if you are entitled to the EITC without using the adoptive child as the qualifying child, you can still claim the EITC.

When the adoption is final and the child has an SSN, you may file an amended return for an earlier year if you find that you could have claimed EITC in the earlier year except for the fact that the child did not have an SSN. Use Form 1040X, Amended U.S. Individual Income Tax Return, and Schedule EIC. The Statute of Limitation for filing an amended tax return is normally three years from the due date of the individual income tax return. More detailed information on filing the amended individual tax return is available in the 1040X Instructions. You can also get copies of any of the forms and instructions mentioned here by calling the IRS at 1-800-829-3676.
