If you don't file then if you do get audited then you loose the benefit of the doubt when you are trying to prove your innocence. Remember that to the IRS, you are guilty until proven innocent. So if they think you are evading taxes, then had you filed at least you could claim you tried, but fucked up.

Great way of putting it in terms of guilty before proven innocent.
So, I’m better off speeding through it and fucking up than to not do it at all. For “legal” reasons.
If they decide to flag you for an audit, all they have to do is send you a letter
If it's really bad you could get insurance
