Yeah, missed the cap bit, makes more sense now. You'd still be raising taxes massively on the lower portion of high earners. You literally have to make millions to pay anywhere close to an effective 30 percent tax rate as it is now. Someone making $400k right now is probably paying an effective tax rate of 20-25 percent. This would raise that by at least $20K and probably closer to $50k or $60k. No one making $400k right now is paying anywhere close to $120,000 in federal income tax.
I'm sure it could use some tweeking in regards to the rates and where they should be applied, but to have a tax code that could be printed on 1 or 2 ages is very attractive to me.
Honestly I don't know why people want such simplicity in something that's inherently complex. The very idea of a progressive income tax structure is that those with more income benefit more from government services. The problem is it's very difficult to determine just how much more they benefit and what their share of funding that government should be.
It's painfully obvious that a store owner benefits more from a well-maintained street than the individuals shopping in said store. If we were to put that store on an island accessed by one bridge and it failed, the shoppers are only out the items they would have purchased there. The owner has lost virtually his entire income.
So you have three parties all with vested interests, the owner, shoppers and the government which sees tax revenue from both. Now both the owner and shoppers have an obligation to pay the government to keep that bridge in working order. The question is how much does the government charge each individual? That's difficult to answer, and subject to change at any moment.
Advocating for a fair tax structure and and a simple tax structure are really two different things.
FWIW, under the current structure, a person making $400k would pay $117,658 for an effective tax rate of 29.4 percent even though they're in the 35 percent bracket. That total includes no deductions, exemptions, credits or deferments. It would be incredibly easy to knock that payment down well below $100,000 with those added in, especially if this person lives in a state that has an income tax.
As an example:
The Bidens reported total income of $379,178 on their 2010 tax return, which consists mostly of the vice president's salary of $255,888 and Jill Biden's salary as a college teacher of $82,488. The Bidens also itemized, taking deductions for state income tax, property tax, mortgage interest, and charity. Like many other taxpayers, the Bidens got hit with the Alternative Minimum Tax. The Bidens paid federal income taxes of $86,407, roughly 23% of their total income.
So even under the AMT, the Biden's paid an effective rate of 23 percent, well below the marginal rate of 35 percent. Also far less than what your plan would call for. And you're still going to need some form of deduction for state and local taxes on any plan.
