Should my 19 year old full time college student not qualify for child tax credit -- I am single parent head of household?

[Hal_Al · Accepted solution]

Yes. That's the law. Any "qualifying child" dependent, over 16, does not also qualify for the Child tax credit.

 This comes as a big surprise to many parents the year their child turns 17. A child over age 16 no longer qualifies for the Child Tax credit (CTC). Although a child can still be a student dependent through age 23, and a qualifying child for EIC,  the Child Tax Credit expires the year they turn 17 and you no longer get the $1000 CTC.
