FYI - for 2017 the personal exemption you got for each person on your return was $4,050. It has been suspended for 2018 and instead you get a double Standard Deduction. But the amount for 2018 would be $4,150. You can't claim someone as a dependent if they make over $4,150 for the year unless they are your child under 19 or under 24 and a full time student.
