<prompt> Human: He most likely would have received a refund for those years. I know he cannot get money back prior to 3 years. He doesnt have any deductions or complications so his taxes should be strait forward. Does he need anything besides his w-2s? Should he bother filing for years further back than 3? Does he need a tax professional or can he use online tax software? My plan was to just goto HR block with him and be done with it.  <response>: Not knowing how much your brother makes, there are many nonprofit organizations that help people file their taxes if they make under a certain amount of money example 50,000 they will often help you pay back taxes or just file for free.
