So after helping my client I decided to drop in my Uncle. My Uncle explained that I had not filed taxes in 4 years and that on the first 3 of those it looks like I did not owe anything but the first 2 I would have been due refunds (no longer available). My Uncle was pleasant and assured me that I'm in no real trouble and told me how to get on with the paperwork.
Did you know that if it looks like you owe money and you don't file a return that the IRS will prepare a return for you (with zero deductions) and send you a bill? That is what I'm working on avoiding with this past year.
