<prompt> Human: Hi reddit, so backstory I have been living with GF for over a year which for the majority of it I have been paying her Auto insurance, Rent, Food, everything but health insurance while we live together and she goes to school using FAFSA grants. Because of this I believe that I should be able to claim her but each of her parents ,who are divorced and she visits alternately would like to. Given that I am the one paying everything that isnt FAFSA i believe that I should be the one claiming her. Any thoughts welcomed!  <response>: The strange thing about qualifying child test is, the person claiming her does NOT need to support her at all! Sources: 1 2 Is your GF her parents QC? Likely, because: She is 21, full time student. She can be considered to have lived with her parent the entire year. Being in school creates the temporary absence exception. This test is probably the point you are arguing on. She is her parents daughter. She did not provide more than 50 of her support no income.
