Last year, I was only refunded a child tax credit for two of my three children. My son was 18, but living in my home full time and a full time student (senior in hs)

How do I get that tax credit if it is due to me?  I am a divorced mom, head of household and it was my year to claim the children. I must have made a mistake somewhere? What did I do wrong and how do I fix it?

You don't get it because it is not due to you. A child qualifies for the child tax credit only when the child is 16 or younger. The moment that the child turns 17, the child does not qualify for the child tax credit for the entire year. That is an absolute age limit. Nothing else matters, not student status or anything else. The moment that the child turns 17, the child does not qualify for the child tax credit for the entire year. That is the tax law and there are no exceptions to it.

Thank you, I didn't realize that- bummer!
