"Catch me if you can." IRS has a massive and sophisticated computer system matching information from many government and private entities, nationally and internationally. It is only a matter of time before IRS catches up with you.
This is not a situation to take lightly. Failure to file your tax return is a criminal offense with potential jail time of one year per each year not filed. Are you willing to risk your personal freedom for not filing your tax return(s)?
If you do nothing and allow the IRS to file your tax returns for you, (Substitute For Return), the IRS will file your tax return(s) in the best interest of the IRS - NOT you. IRS typically uses the least amount of deductions if any you are entitled to.
