First, you can't go to prison for not filing your taxes. You CAN go to prison for LYING on your tax forms (unless you're Hillary, then an apology makes everything all better). The taxes taken out of your paychecks are an estimate of your tax liability based on your wages. Say two people have the same job, making the same pay. Bob has no other income while Ashley gets $50,000 a year in dividends from stock she owns. Bob's income tax will be much less than Ashley's both have to file income tax returns to calculate the exact amount of their taxes; Bob will probably get a refund while Ashley will probably have to pay several thousand dollars more. If you haven't filed your taxes for several years, you need to consult a tax attorney.
