Me and my girl friend are living together she has a child 3 years old, I am wondering how we should file our taxes we have lived with each other over a year. Side note, she doesn't get to claim her child this year or next. I made more money then she did should we file together and me head of house hold or should we file separate? and her head of house hold. If you have any questions about the situation to make it more clear please feel free to ask thanks!
