I'm a travel speech therapist from MI and live with my sister and parents there when not traveling for work. This is my first travel job, and I am in CA during the school year. I'm getting a tax-free stipend for housing, meals, living expenses, etc. I pay $300 to my sister every month as a shared cost/room rental for her house. I also pay my car insurance in MI, outside of the $300/month. Everything in my name is based out of MI - like bank accounts, car loan, credit cards, etc. Is keeping everything in my name with a MI address and the $300 enough to make the MI home my "tax home"? I wasn't sure if the $300 should be more or not.
Also, would it make sense to have a room rental agreement with my sister for the $300 to make it more official? And would my sister have to claim the $300 as income if we do that?
