IRS Form 15100 Spanish – IRS Forms, Instructions, Pubs 2026 – If you are a Spanish-speaking adoptive parent in the United States and need to extend your child’s Adoption Taxpayer Identification Number (ATIN) or update the IRS about their Social Security Number (SSN), the IRS Form 15100 Spanish (Formulario 15100 (SP)) is the official document you need.
This free Spanish-language form lets you request a one-year extension of the ATIN, notify the IRS if you’ve received your adoptive child’s SSN, or report an address change. It is the exact Spanish translation of the English Form 15100 and is fully accepted by the IRS.
What Is an ATIN and Why Do You Need Form 15100 Spanish?
An Adoption Taxpayer Identification Number (ATIN) is a temporary nine-digit IRS-issued number for a child in a pending domestic (or qualifying foreign) adoption when the adoptive parents do not yet have the child’s Social Security Number (SSN).
You need an ATIN to claim the child as a dependent on your federal tax return or to claim the Child and Dependent Care Credit while the adoption is still pending. Without a valid identifying number (SSN or ATIN), you generally cannot claim these benefits.
- Initial ATIN validity: Up to 2 years.
- Reminder notice: The IRS sends CP561A approximately 3 months before expiration.
- Extension option: You can request one additional year using Form 15100 (or the Spanish version) if the adoption is not yet final.
Important: An ATIN cannot be used to claim the Earned Income Tax Credit (EITC)—only an SSN qualifies for EITC.
Who Should File IRS Form 15100 (Spanish Version)?
Use the Spanish Form 15100 (SP) if you are an adoptive parent who:
- Received a CP561A notice (ATIN expires in 3 months) and need to request the 1-year extension.
- Received a CP562C notice requesting more information for your prior extension request.
- Have now obtained the child’s SSN and want to notify the IRS (so the ATIN can be deactivated).
- Need to update your mailing address since you originally applied for the ATIN.
The form is designed specifically for Spanish-speaking families and uses clear Spanish terminology (e.g., “Solicitud de prórroga del Número de identificación del contribuyente en proceso de adopción (ATIN)”).
