based on what you provided he would be a qualifying child for 2020 unless he is over 24 at the end of the year. to be a qualifying relative (a dependent)  his gross earnings must be less than $4,300 for 2020.

Thank you yes he was a student for 8 months of the yr i will put him down as a full time student but now i am wondering when he gose to file his taxes cause he did work how will that affect his taxes or will it affect mine  he is only 19 yrs old 

So even if he was a full time student i still cant claim him just cause he made over 4300 and he is only 19yrs old and i pay everything for him 

Be sure he checks the box on his return that says someone else can claim him.
