Just need to know if I can file my fiances taxes from 2006?? I am his power of attorney and he has been incarcerated since June of 2006 but was working up until he took his plea. I just dont want him to come home with yet another problem hanging over our heads. I have all the paperwork i need to file (i think). If i can do his taxes can I do like Turbo Tax or do I have to go to some place like H&R Block??? Thanks in advance for your help!!
