This credit is for certain individuals who get less than the full amount of the child tax credit. The additional child tax credit may give you a refund even if you do not owe any tax.
Make sure you figured the amount, if any, of your child tax credit.
If you answered “Yes” on line 9 or line 10 of the Child Tax Credit Worksheet in the Form 1040, Form 1040A, or Form 1040NR instructions (or on line 13 of the Child Tax Credit Worksheet in this publication), use Parts II–IV of Schedule 8812 to see if you can take the additional child tax credit.
If you have an additional child tax credit on line 13 of Schedule 8812, carry it to Form 1040, line 67; Form 1040A, line 43; or Form 1040NR, line 64.
Taxpayer identification number needed by due date of return. If you do not have a social security number (SSN) or IRS individual taxpayer identification number (ITIN) by the due date of your 2016 return (including extensions), you cannot claim the child tax credit or the additional child tax credit on either your original or an amended 2016 return, even if you later get an SSN or ITIN. Also, neither credit is allowed on either your original or an amended 2016 return for a child who does not have an SSN, ITIN, or IRS adoption taxpayer identification number (ATIN) by the due date of your return (including extensions), even if that child later gets one of those numbers.
If you apply for an ATIN or ITIN on or before the due date of your 2016 return (including extensions) and the IRS issues you an ATIN or ITIN as a result of the application, the IRS will consider your ATIN or ITIN as issued on or before the due date of your return.
