<prompt> Human: Im 21 years old and I live with my girlfriend and our 6 month old daughter. I made 40k this past year and my girlfriend worked half the year making 13k14k. I think its also important to note that I cover all of our household expenses. We decided that she would claim our child without filing as head of household. Although Im not claiming any dependants, would I qualify to file as head of household?  <response>: You can not be head of household without supporting somebody. If you want HOH, you have to claim your daughter.
