Why couldn't I claim child tax credit on my 17 year old daughter who lived with me the whole year and was in school?

Your child is  too old (over 16). 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.

Makes absolutely no sense!  18 is suppose to be considered an adult?! What is a 17 year old called "Adoldult"!
