Father claimed me on his taxes despite living several hundred miles away and me being an adult? Long story short, I'm renting from my father's mother, but my father's name was still on the bills relating to the home until very recently. Because of this, my father claimed me as a dependent on his taxes; to do this, he would have also had to state that I am disabled in some way and at least 50% dependent on him. Neither of those are true, and he has apparently upheld these falsehoods for years.

What are my options? What can I do in this situation? Would there be any repercussions toward me were I to report him, and how can I report him?
