Question: how much money do you need to make to claim a dependent?
Answer: Your relative must live at your residence all year or be on the list of “relatives who do not live with you” in Publication 501. About 30 types of relatives are on this list. Do they make less than $4,200 in 2019? Your relative cannot have a gross income of more than $4,200 in 2019 and be claimed by you as a dependent.
