<prompt> Human: My parents are divorced, and my father has claimed me as a dependent in his 2013 tax forms even though I have only lived at his out-of-state residence for less than two weeks last year. I am 21 years old and a college student, but my father does not support me financially other than adding me to his health insurance. All housing, tuition, living expenses, and other insurance fees are paid from my personal bank account and by my mother. I did not consent to his claiming me as a dependent; in fact, I planned to have my mother file on my behalf because I reside with her when I am not in college, but she is apparently now unable to do so because my father has preempted that opportunity. Is there anything I can do about this, given that he has already turned the forms in?EDIT: Thanks everyone for your responses! To clarify, nothing regarding me or filing taxes on my behalf were mentioned in the divorce settlement because I was 19 when they divorced, so there wasnt a custody or child-related agreement. I live with my mom for less than half the year and she pays less than half my expenses, as Im a full-time student with a scholarship that covers my yearly expenses.  <response>: Same thing happened to me and my brother in college...really tricky and not so fun situation. I needed to be my moms dependent to fill out necessary paperwork, but my dad was claiming me first.Aside from going to the IRS directly, my parents werent really in tune with college fin aid, forms, etc they each just wrote me a small check here and there without questions. What I did was tell whichever parent was in the wrong that I already filed school financial aid paperwork and that it was cross referenced with parents SSN that I put on there, and that they warned against being Audited if things didnt line up. This generally scares the living hell out of parents...if theyre already being dishonest and claiming you, you know theyve claimed some other random stuff thats a no-go for the IRS.TL:DR tell the wrong parent doing this will get them auditedreported by school financial aid that youre directly working with, and theyll get scared out of messing your situation up.
