<prompt> Human: Im a 21yo and Ive never filed taxes. Ive only been working for 3 years and I make 60kyr. My dad told me not to worry about taxes because he would still be claiming me as a dependent. I thought this made sense because I live in one of his rental properties rent free so I thought although I can afford everything myself I was still technically dependent on him for a place to live, all the bills are in his name but I pay for everything myself.For the last couple of years weve done it this way and everything seemed ok. He called me yesterday while visiting with his accountant and asked me if I had filed my taxes this year, I told him that he told me not to worry about taxes as long as I was living in his house but he seems to have no memory of this and told me not only will I be fined for paying late Ill also be fined for the years I didnt pay. Also this isnt a case of me misunderstanding something he said I talked to my mom and she also remembers him telling me not to worry about taxes.How serious is this? Am I looking at serious fines? Does this in any way affect my credit score, ability to mortgage a house on my own?  <response>: Sigh. You need to file your tax returns for the last three years that youve been working. Depending on how your withholding was, you may not owe much or anything.Your father will likely have to refile for previous years if he has been claiming you as a dependent.
