It depends. You may be able to claim your sister as a "Qualifying Relative." The requirements for a Qualifying Relative are below:
- 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. More info
When you add someone as a dependent, TurboTax will ask a series of
questions to make sure you can claim them. This is the easiest way to determine if someone is your dependent.
