Get your taxes done using TurboTax

A 16 year old is presumed to be a student and is your qualifying child dependent -- whereas a 19 year old might or might not be a qualifying child dependent.   If your 19 year old is not a student they cannot be claimed as a qualifying child and might not be a dependent at all if they had over $5050 of income.  Asking if she was a student helps to determine if you can claim a 19 year old as a dependent.

 

WHO CAN I CLAIM AS A DEPENDENT?

 

You can claim a child, relative, friend, or fiancé (etc.) as a dependent on your 2024 taxes as long as they meet the following requirements:

Qualifying child

  • They're related to you.
  • They aren't claimed as a dependent by someone else.
  • They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
  • They aren’t filing a joint return with their spouse.
  • They're under the age of 19 (or 24 for full-time students).
    • No age limit for permanently and totally disabled children.
  • They lived with you for more than half the year (exceptions apply).
  • They didn't provide more than half of their own support for the year.

Qualifying relative

  • They don't have to be related to you (despite the name).
  • They aren't claimed as a dependent by someone else.
  • They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
  • They aren’t filing a joint return with their spouse.
  • They lived with you the entire year (exceptions apply).
  • They made less than $5050 in 2024 (not counting Social Security)
  • You provided more than half of their financial support.

When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them. There may be other tax benefits you can get when you claim a dependent.
