You don't say if the person was related or not, so I am listing both options. The easiest way to tell if someone qualifies is to fill out the interview in TurboTax and we will let you know if the person (child) qualifies.
1) You can claim a child -
or grandchild - as a dependent on your 2017 taxes as long as they meet the
following requirements:
- They are related to you.
- They aren't claimed as a
dependent by someone else.
- They are a U.S. citizen,
resident alien, national, or a Canadian or Mexican resident.
- They aren’t filing a joint
return with their spouse.
- They are under the age of 19
(or 24 for full-time students). There is no age limit for permanently and
totally disabled children.
- They live with you for more
than half the year (exceptions apply).
2) 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 are 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.
- They made less than $4,050 in
2017.
- You provided
more than half of their financial support.
