Can I get the Child Tax Credit for a child with an ITIN, not a social security number?
Yes, with an individual tax identification number (ITIN), you can claim the Child Tax Credit if you otherwise qualify. The Child Tax Credit can only be claimed by the parent claiming the child as a dependent.
Please refer to the Form 1040 Instructions or the Form 1040A Instructions index for the Child Tax Credit. The referenced pages will explain who qualifies for the Child Tax Credit, and how to calculate it.
