I have two children, both from different fathers. Last year my oldest and I moved in with my boyfriend who is the father of my second child. My oldest father is still in her life, but she was with me for all of last year. My question comes from when my boyfriend's mother offered to file his taxes (as she has done with him very year and with me last year). We previously had agreed that he would claim our son and I would work with my oldest father to determine how we would go about claiming her on taxes. Well, we have come to find out that his mother saved my oldest SSN and filed her on his taxes as well as a qualifying child. I made around $15000 last year, so I have to file and so does my eldest's father. Is he allowed to do this? If not, what should we do to avoid a super lengthy hold up if at all possible?
