The only difference between the current system and a (still fictional) flat tax concept is that the evading schemes today are built in and ratified.
No. A flat tax revels in its simplicity. That basically eliminates most of the tax code and replaces it with a very simple single rate applied to all income. A flat tax is
never described as maintaining all of the complexity regarding what is income and when it is income of existing systems.
And they tend to change all the time. People still evade taxes today with the progressive tax system, so if you're saying that people wills still try to evade taxes whether it's a progressive tax or a flat tax - I would agree... there will always be those who attempt to evade taxes.
Depends what you mean by change. Yes changes happen here and there regarding items and brackets, but it the underlying treatment of what is income and when it's declared don't People will try to evade taxes under any system, but you take away bright line rules and it gets a heck of a lot easier to cheat. Furthermore, it actually becomes legal to cheat because there would be no complex laws preventing tax schemes.
Can you provide some examples of what you're talking about?
Let's start with the basics. Do you understand the concept of deferred revenue? How about reserve accounts? Tax law differs quite a bit from GAAP/IFRS.
To be fair, we don't know what a flat tax would look like in an actual implementation. You're making assumptions on what a flat tax would be based on what is reported in the media, what people write about, etc... we've actually never seen an actual blueprint of a flat tax so it may or may not address when and what is income.
Well, we've never really seen a true flat tax either. Eastern European is still somewhat progressive even as it's declared to be flat. Furthermore, I'm basing my argument off of the simplicity arguments regarding why a flat tax is better. I've never seen any politician argue for a flat tax that keeps much of the complexity regarding what and when. Perry's arguing right now for a tax system so simple it will fit on a single piece of paper. That is guaranteed to remove the laws prohibiting illegal shelters.
IMO the tax code does not have to be complex
Want to explain how we get around what is income and when with a simple code?
First, no one should be taxed on the return of capital. But there are ways currently that are prohibited that prevent the creation of fraudulent basis. Some of these rulings, procedures and regs are dozens of pages long. Most of them came about because someone gamed the system. If we go to a simple "Everything" is income, that renders a real risk of taxing things that aren't income, such as return of capital to taxation. Furthermore, it forces people to pay taxes on legitimately deferred income. It's pretty absurd to tax people on income they won't constructively receive for years.
A little example, if we remove the regulations regarding revocable trusts which are somewhat lengthy, people could donate money into trusts they can change and not pay taxes on it on their rates because it's no longer technically under them. The laws regarding revocable prevent this right now as a way of stopping people from hiding income. People use to put large amounts of assets that would generate income in the future into such trusts and then not pay at their rates but under trusts rates effectively avoid large amounts of tax.
There are
plenty of these kinds of historical examples that make up huge portions of the 3 trillion word tax code. You get rid of transfer pricing regulations and Exxon goes back to selling crude to its Cayman subsidiary for close to the price it sells to refineries in the US and results in exceptionally low corporate taxes. The tax code is complex partially because it HAS to be complex.
but it is to support the loopholes and deductions which politicians put in - and they put those things in there for selfish reasons, such as re-election, election / campaign support, etc.
To a certain degree yes, but to a certain degree no.
The tax code and the revenue it brings in is Congress's play thing. The more control that can be exerted over it, the more control over the money - and the more control over the money the more power, regardless of political affiliation.
I don't think you quite get the notion of the concept of what is income and when it is income. Like most people you seem fixated on the deductions/credit portions. Which really isn't that big of a concern.
