A few points:
- Are we talking one big flat tax that covers everything, or are we simply talking about a flat income tax, accompanied by the existing panoply of regressive sales taxes, gas taxes, payroll taxes, etc.?
Because right now, we only have two progressive taxes, really: the income tax and the estate tax. All other taxes of any significance, AFAICT, are either already essentially flat (e.g. most states’ income taxes, which tend to hit the top rate at amounts like $12K), or regressive (like the taxes I just mentioned).
There’s an argument for making the overall system of taxation in this country a flat one. I disagree with that argument, but there’s an argument to be made for it. But I can’t see an argument for making the income tax flat, but accompanied by a panoply of regressive taxes that would insure that, overall, Joe and Jane Sixpack pay a higher share of their income in taxes than the rich.
- As others have pointed out ahead of me, tax simplification and the flat tax are two separate and independent notions. One can keep or get rid of deductions and exemptions just as easily with a flat or progressive tax structure.
I’m all for getting rid of all the deductions, and keeping only the personal exemptions and the standard deduction. I’d cheerfully give up my mortgage interest and property tax deductions, my deduction for charitable contributions, and all the rest, if all the other deductions I don’t use are also killed.
- I think the succinct logic for a graduated tax scheme can be encapsulated as follows:
a) the utility of the next dollar of income decreases as one’s income increases; and
b) the effort involved in gaining that next dollar of income also decreases as one’s income increases.
To someone making $20K a year, a $5K raise is a godsend. To someone earning $65K a year, it’s routine. To someone earning $200K a year, it’s a disappointment.
- In response to Martin Hyde’s list, I note that it includes the taxes paid by the top 1% and the top 10% at various times; I note as well the absence of the corresponding income number. If income is getting more concentrated in the top 1% or 0.1% or even 0.01%, they should pay a larger share of taxes, but I would hardly regard that as a net good.
What would be more illuminating is to see the taxes paid by the top 1%, 10%, etc. of income, rather than the top 1%, 10%, etc. of earners.
- If we take income and payroll taxes together, we already essentially have a flat tax (PDF - see Figure F on page 6), thanks especially to the 2003 tax cuts, which reduced the tax rate on dividends to less than what I pay on most of my wage income.
Figure F shows the average tax rates (including the Social Security payroll tax) on verious income groups, in 1979, 1989, 1999, and (the last line) what the average tax rates would have been for the 1999 tax cohort if the 2001 and 2003 tax cuts had been in effect then.
What it says is that the top 0.1% pay an average combined Federal income/SocSec tax rate of 22.57%. For the top 1%, excluding the top 0.1%, it’s 23.34%. Maybe this would be better in tabular form:
Income
Bracket . . . . Avg Tax
>0.1% . . . . . 22.57%
0.1 - 1.0% . . 23.34%
1 - 5% . . . . . 25.76%
5 - 10% . . . . 25.48%
10 - 20% . . . 23.81%
20 - 40% . . . 21.58%
40 - 60% . . . 18.25%
60 - 80% . . . 10.94%
80 - 100% . . . 6.97%
So it’s pretty flat until you get down towards the bottom, when it attains a bit of progressivity. And average taxes actually go down a bit as one gets into the top 1%, and more so in the top 0.1%.
I’m somewhat startled by the mildness of the progressivity in the 1979 numbers. It was a lot more progressive then than now, but still…31.92% average tax rate for the top 0.1% of earners, v. 17.35% for the middle quintile? That’s progressive, sure, but it’s hardly what I’d consider a crushing burden on the richest of the rich. (YMMV, of course.)
But if we combine the graph in Figure B (p.3) with the data in Figure E (p.5), we get something like what I was asking for at the end of part (4) above. In 1999, the top 0.1% earned just under 10% of the income, and the rest of the top 1% earned just over 10%, for a total of ~20% for the top 1%. In 1999, the top 1% paid 23.32% of the combined income and SocSec taxes. Outrageous, huh? Fortunately, help was on the way: if the 2001 and 2003 tax cuts had been in effect then, they would have only had to pay 20.83% of the taxes, on their 20% of the income.
So the rich weren’t exactly getting socked then, and even less so now.
