<prompt> Human: Just going through an existential crisis in realizing Im in my mid-twenties have held a cash paying job for the last 5 years, which I want to get out of now have not been paying taxes on. I have had a bank account for this whole time that I deposit most of my check into every 2 weeks. I want to take my experience get away from my current job that Im unhappy with advance into a legitimate job with an actual future. But Im scared now that Im going to get hit with some crippling back-taxes or penalties when I go back to W9 filing my taxes. Have I completely fucked myself or no? Any advice appreciated  <response>: All due respect, you deserve to get hit with back taxes. Paying taxes isnt optional, not doing it is a felony, and you owe income and FICA tax on that money whether your employer withheld them or not.
