to make over 500k income should be audited every year. Every freaking year.
Anyone that claims to make 50k income a year or less should be tax exempt.

to escape audits and taxes.

Audits are a necessary evil, from the wealthy on down. It's way too easy for the wealthy to shelter income from taxes as it is; your proposal would make it even easier. The Greeks have had major, major issues with this kind of tax evasion (their wounds are not entirely self-inflicted, but their taxation/tax collection issues have certainly hindered their ability to recover without completely cannibalizing the base of their economy).

Sadly even the poor must be audited sometimes; otherwise you will have people who are really wealthy claiming to be poor. The issue comes when the least of society are audited so much that the IRS spends more to audit than it recovers in funds from tax cheats, or when the IRS audits those least able to afford legal counsel, while looking the other way while people like Rmoney hide million$ offshore. I certainly don't advocate oppressive taxation (and people who really don't have the means to defend themselves in tax court should truly be offered legal assistance similar to what public defenders are supposed to do), but the possibility of an audit should always be there, for anyone who is obligated to file taxes. If a certain category of taxpayer is exempt, non-exempt taxpayers will lie, steal and cheat their way into the exempt category, by hook or by crook.

which is reported from your employer right? That's what I meant. Reported by your employer.
Where are the check and balances for those that file? Through the audits. We have it all backwards in this country. The employer should report your income, not individuals.

and if you have allowable deductions and/or your income changed, you would have the option to file an amended return. That's the way most countries do it. Employers already report that kind of information, so the IRS already has what it needs to do a W-2 tax return for the vast majority of Americans.

However, the same wealthy tax cheats that would abuse the shit out of a no-audit loophole are also the same wealthy tax cheats who have income from sources that are...less likely to be automatically reported to the IRS. Hence why they need to be audited, and the threat of an audit needs to hover over every taxpayer (else the tax cheats will cheat their way into an audit-exempt income bracket).

Tax preparer lobbyists, however, is why we can't have a good thing: Every time this comes up in Congress, the army of H&R Block, Intuit, Jackson Hewitt, etc. lobbyists come out of the woodwork to bribe our esteemed politicians to not make their employers redundant.

that understand what I meant. thank you.

You really don't see the obvious problem with this suggestion?

less people making enough money to justify an audit !

A big part of the auditing process used to be ensuring that all of the numbers YOU reported actually matched what everyone else said they gave you, or what you say you gave away. Nowadays most of that is submitted or processed electronically, so these conflicts are caught without the need for an actual audit. A few years ago I actually received a small additional check from the IRS without even asking for it. Apparently I'd mistyped one of my income numbers and made a math error when I was doing my taxes. Their computers caught it, recalculated my taxes, and they sent me a check for the difference when they found that it worked to my favor. I'd never even HEARD of that sort of thing before.

From that perspective, you COULD say that 100% of individuals are audited.
