I lived with a friend this past year until here recently. During that year I had a daughter who also lived with me. Now the friend and I are no longer living together, and are no longer friends. He wants to claim my daughter who is not his child on his taxes this year.
Is that even legal? He doesn't have her information to claim her (I would have to give it to him) and I'm not sure if I should allow this or not. I know his tax prepper, and she will allow him to continue claiming her each year despite her no longer residing with him, which I know is illegal. So should he be allowed to claim her this year since he did support her and I for the better part of 8 months? If I claim her, would it come back on me for an audit since our address was the same as his for most of the year?
