<prompt> Human: Okay so Im 17 will be 18 in a few days, and I have 10 month old child, ive been living with my boyfriend also his daddy for over a year now, and he was wanting to file me and our child on his taxes, but my mom says he cant, she has to file me and my child because weve been on her insurance with her address. Note: hes took care of both of us as far as food, clothes, etc! Help! Is it true that he cant file us?  <response>: There are complicated rules, in IRS Publication 17 chapter 3. One first question: who did you live with during most of the year? If you did not live with your mother more than half the year, ... how much income did you earn?If under 4050, can your mother rightfully say she provided more than half the cost of your support? Housing, food, utilities, education, insurance, etcIf she cannot, and you lived with your BF and he did provide over half your support, you can be his dependent qualifying relative.Your child cannot be claimed by your mom if father lives with and chooses to claim the child.Ask your mom what insurance has to do with tax filing. She might be confused about definition of insurance dependent coverage. Or, if she covered you on an Obamacare plan, she may not know about what to do if you are no longer in her tax household.
