<prompt> Human: I turned 18 last year and Ive been working full time for a few months now. I live with my mother and Ive been anxious to do my taxes for the first time so I can get an understanding early on about the process. However, my mother keeps trying to prevent me from doing them because she hasnt filed in 2-3 years and shes worried if I file mine, the government will wonder where the rest of my families are. We have a close family friend that is an accountant and offered to do all of ours and says that it is better to file together. Does she have a reason to worry about it? Is it better to file together? This is all new to me. Thank you! Edit: I live in Ontario, Im sorry that I should have clarified that. We have up to 7 years to file back taxes. She makes 120,000year and get paid from a company not under the table. I make at 25,000 and get paid from the same company.Assistant: Your mother is trying to make you commit a federal crime. Dont do it. File.Human: I dont live in the U.S, Im sorry I should have clarified that. I live in Ontario and we have up to 7 years to file.  <response>: Canada also has a federal government. My own father in law hasnt filed his taxes in about 10 years. They have leveraged a quarter million dollar lein against his house until such time as he straightens it out.
