The following criteria must be met to claim someone as a qualifying child:
- Your child (including adopted and foster children), your sibling, or a descendent of any of them.
- Age 18 or younger at the end of the tax year OR under 24 (and younger than you and your spouse) if they are a full-time student
- Lived with you for more than 6 months during the tax year
- They did not provide more than half of their own support (social security does not count)
- They did not file a joint return, unless it was to claim a refund
- Have a social security number that is valid for employment
All of the above are true. I did not understand what is meant by, they did not file a joint return?
