I have been unemployed for the last five years as I was attending school full time and trying to excel with my studies. I was lucky enough to have a cheap cost of living which was paid by my school refund. My questions are apropos to my taxes. I haven't filed because I had read that since I have no income, I wouldn't be required to file. I need to know if I should file; and if so, can I go back and repair the damage of not filing for a few years? I also would like to know if there are any tax breaks or rebates or credits I can get from my student loans? I had heard that there were a certain amount of rebates per credit. Is this information false?
