Economically, you sort of live in a flat tax. (https://www.nytimes.com/interactive/2019/10/06/opinion/income-tax-rate-wealthy.html https://www.nytimes.com/interactive/2019/10/06/opinion/incom...) I know that's not what you mean. But if you simply filed a 1040EZ, then paid a 20% penalty when the IRS sends you a letter saying pay the rest of what you owe, expect to pay... 28 percentage points effective instead of 26. This is to say that tax complexity is a red herring. You can already live in an almost zero-complexity tax obligation personally, as a wage earner, above and beyond what is officially prescribed. It's not really what it's about. It's probably not about saving money either.
