IRS Form 15101 – Provide SSN for Adoptive Child (Fillable PDF)

IRS Form 15101, Provide a Social Security Number (SSN) for Adoptive Child, is used by parents who have received an Adoption Taxpayer Identification Number (ATIN) and later obtain the child’s SSN. The form notifies the Internal Revenue Service (IRS) of the new SSN so the ATIN can be retired.

What Is IRS Form 15101?

This one‑page form collects basic contact information for up to two taxpayers, the child’s SSN, the child’s name, and the original ATIN. It is required only after the adoption is final and the child’s SSN is issued.

How to Complete the Form

Follow these steps to fill the form quickly:

Enter the name(s) and Social Security Number(s) of the adopting parent(s) at the top.
Provide your mailing address, phone numbers, and preferred contact times.
Enter the child’s SSN exactly as it appears on the Social Security card.
Write the child’s full legal name.
Enter the ATIN that was previously assigned.
Both parents must sign and date the form.

Common Mistakes to Avoid

Leaving the ATIN field blank – the IRS needs this to match the previous filing.
Using an outdated address – update your address on Form 8822 if it has changed.
Signing only one side when filing jointly – both spouses must sign.
Submitting the form before the child’s SSN is officially issued.

Where to Submit the Form

You can mail the completed form to the IRS address printed on the second page, or fax it to (855) 250‑1731. If you received a CP‑561C notice, attach the notice stub before mailing.

ABOUT

Internal Revenue Service (IRS) Forms

IRS Form 15101 is one of the official tax forms used in the United States to report income, claim deductions and credits, calculate tax liability, and fulfill other tax-related obligations. The IRS is the federal agency responsible for administering and enforcing the internal revenue laws in the United States.

Here are some examples of Internal Revenue Service forms:

Form 1040: This is the primary individual income tax return form used by most taxpayers. It is used to report various types of income, claim deductions and credits, calculate tax liability, and determine whether a taxpayer owes additional tax or is entitled to a refund.

Form 1099: There are different variations of Form 1099, such as 1099-MISC, 1099-INT, 1099-DIV, etc. These forms are used to report income received by individuals or businesses from various sources other than employment, such as self-employment income, interest income, dividend income, and rental income.

Form W-2: This form is used by employers to report wages paid to employees and the taxes withheld from their pay. Employees use the information on Form W-2 to complete their individual tax returns.

Form 941: Employers use this form to report employment taxes, including federal income tax withheld, Social Security tax, and Medicare tax, for their employees.

Form 1065: This form is used by partnerships to report their income, deductions, and tax liability. Partnerships themselves do not pay income tax; instead, the partners report their share of partnership income on their individual tax returns.

Form 1120: This is the corporate income tax return form used by C corporations to report their income, deductions, and tax liability.

Form 990: This form is used by tax-exempt organizations, such as nonprofits and charities, to report their financial information, activities, and compliance with tax laws.

Form 8862: This form is used by taxpayers who previously claimed the Earned Income Tax Credit (EITC) but had it disallowed, and now want to claim it again.

These are just a few examples of the numerous IRS forms that exist to fulfill various tax-related obligations. The specific forms required for an individual or business depend on their unique circumstances, income sources, and deductions. It's advisable to consult the official website of the Internal Revenue Service (www.irs.gov) or seek professional tax advice to obtain accurate and up-to-date information regarding the specific IRS forms relevant to your tax situation.
