Hi guys, My girlfriend is a student and just started investing late last year. She bought and sold a couple of stocks (literally) and bough and sold a few options, with very little profit mainly to get used to how things work. Now here is my question: does she have to file taxes even though she made maybe $50? I guess is also worth mentioning that she is a foreign student, so I was wondering how tax laws applies to her. Any help is much appreacited.
