Can i claim my adult child as a dependent?

Standard

Factors that affect whether an individual is a “qualified child” include:

Relationship. The individual must be your child, stepchild, foster child, sibling, stepsibling or a descendant of one of those (i.e., a grandchild).

Age. They must have been under age 19 at year’s end, or under 24 if the child was a full-time student for at least five months of the year.

Residence. The child must have lived with you for more than half of the year. There are some exceptions for children of parents who are separated or divorced.

Support. The child cannot have provided over half of his or her own support during the year.
