Form IT-213-ATT: Child Information for the Empire State Child Credit (2025)

Form IT-213-ATT is a supporting schedule issued by the New York State Department of Taxation and Finance. It’s used to report information about qualifying children when a taxpayer claims more children than can fit on the main Form IT-213, which is the form used to calculate the Empire State Child Credit. If you’re filing for the credit and have more than a handful of qualifying children, this attachment is where the additional details go.

The Empire State Child Credit is a New York State tax credit for residents with qualifying children under age 17. It works similarly in spirit to the federal Child Tax Credit, but it’s calculated separately under New York rules and claimed through the state return. Form IT-213 is the primary form for this credit, and it includes space for a limited number of children. When a household has more qualifying dependents than the main form can accommodate, IT-213-ATT picks up the overflow, listing each additional child’s name, Social Security number, date of birth, and relationship to the taxpayer.

Who Needs to File This Form

You’ll need Form IT-213-ATT only if you’re already filing Form IT-213 and you have more qualifying children than the primary form allows. In practice, this applies to larger families claiming the Empire State Child Credit for tax year 2025. If your household has just one or two qualifying children, you likely won’t need this attachment at all, since the main form has room for that information directly.

It’s worth noting that this form doesn’t stand on its own. It’s strictly a supplement to IT-213, so you can’t file it by itself or use it to claim the credit independently. Think of it as an extension sheet rather than a separate application.

When to Use Form IT-213-ATT

You’ll complete this form during the same tax season you’re filing your New York State income tax return, typically alongside Form IT-201 or IT-203. Since the Empire State Child Credit is tied to your state filing, the attachment gets submitted with your annual return package rather than at any other time of year. If you’re preparing your 2025 tax year return and realize partway through that you have more qualifying children than the main IT-213 form has space for, that’s your cue to pull this attachment into your paperwork.

Families sometimes overlook this requirement because they don’t expect to need a second sheet. If you’re unsure how many children the primary form accommodates, it’s worth checking the instructions for Form IT-213 before you start filling anything out, so you don’t end up redoing sections later.

How to Get and Fill Out the Form

Form IT-213-ATT is available as a fillable PDF directly from the New York State Department of Taxation and Finance website. Because it’s an AcroForm, you can type your entries directly into the PDF fields on your computer rather than printing it out and writing by hand. This tends to reduce errors and makes for a cleaner submission, especially when you’re listing several children’s information in a row.

When completing the form, you’ll need each additional child’s full legal name, Social Security number, date of birth, and relationship to you as the taxpayer. Double-check that Social Security numbers match what’s on file with the Social Security Administration, since mismatches are a common reason state returns get flagged for review. Once filled out, the form gets attached to your IT-213 and filed together with your full New York State return.

If you’re also claiming other New York credits this season, it helps to review related forms as part of your overall filing. For instance, if you have earned income and qualify for a similar benefit, Form IT-215 for the Earned Income Credit might apply to your situation as well. Taxpayers dealing with depreciation issues on property might also want to look at Form IT-211, and those with business investments should check out Form IT-212 for the Investment Credit to see if it fits their filing needs.

Keeping all these forms organized before you sit down to file can save a lot of back-and-forth later, particularly if your household qualifies for multiple state credits in the same tax year.
