<prompt> Human: Non-native US resident here. I have been filing my taxes with tax experts. As I come from tech sector, I have many friends who earn in the same bracket but when such discussions arise, I usually hear a different tax refund for each one of them. Can anyone explain?  <response>: Different withholding, different deductions, a lot could be going on here. The consequences are that the IRS will penalize you heavily for tax fraud, and you can even go to prison for it.
