I have a child in my care all year, under 17, fulltime high school student, with a SS# but I'm not qualified for the tax credit?

[DaveF1006]

To clarify, is this your child?

[xmasbaby0]

You have not explained if the child is related to you in any way----we do not know how to interpret 
"under my care."    Are you asking about the child tax credit?  Or something else?

IRS interview to help determine who can be claimed:
