IRS Form 15110 – Fillable PDF (Additional Child Tax Credit)

Form 15110 is the Additional Child Tax Credit Worksheet the IRS sends when you receive a CP08 notice. It lets you claim any refundable portion of the child tax credit that wasn’t captured on your original return.

What Is Form 15110 and When Do You Need It?

This one‑page worksheet collects:

  • Taxpayer contact information
  • Social Security numbers for you, your spouse, and each qualifying child
  • Eligibility details for each child (age, relationship, residency, etc.)

If the IRS has told you to complete Form 15110, you must return it with any required supporting documents to claim the additional credit.

Common Mistakes & Tips for a Smooth Submission

  • Social Security numbers: Double‑check every SSN. A missing or transposed digit will delay processing.
  • Child eligibility: Verify that each child is under 17, lives with you > ½ year, and is a U.S. citizen or resident.
  • Address changes: Use the most recent address on your last filed return; update it in the form if needed.
  • Signature: The fillable PDF allows you to type a digital signature. Make sure it’s legible.
  • Supporting documents: Attach any required proof (e.g., birth certificates) as separate PDFs when you upload your response.

    No. With Formize you can fill out the form directly in your web browser. If you prefer, you can also download the PDF and use any standard PDF reader.

  • What is a CP08 notice?

    A CP08 notice is sent by the IRS when they need additional information to process your claim for the Additional Child Tax Credit. The notice includes Form 15110.

  • Can I use an ITIN instead of an SSN for my children?

    No. For the child tax credit and additional child tax credit, each qualifying child must have a Social Security Number before the tax return due date.

  • How many children can I list on Form 15110?

    You can list up to three qualifying children on a single Form 15110 worksheet. If you have more, you must submit additional worksheets.

  • Is there a filing deadline for Form 15110?

    You should return the completed Form 15110 as soon as possible after receiving the CP08 notice. Late submissions may result in a reduced credit.

  • Do I need to attach proof of residency for each child?

    Typically the IRS only requires the worksheet, but if they request additional documentation, you may need to provide school records, medical bills, or a lease showing the child lived with you > ½ year.
