Marginal Tax Rates

Posted on by

I have been toying around with the idea of a free money allowance as a prebate for a unified flat income tax. The numbers are interesting, if a bit disheartening. I had hoped to push a 25% flat rate with possibly a higher rate for the really rich. (As long as Warren Buffet, George Soros, and Hollywood vote Democrat it is fair to say the really rich could use a bit more taxes.) Alas, it looks like a higher rate would be needed to break even for the well off.

Anyway, I think you will find the current tax rates to be instructive. I took five of the federal income taxes collected on working class. (I omitted unemployment insurance.) Then, I did a bit of algebra in order to to treat employer portions of FICA and Medicare as part of salary in order to be able to compare a single flat tax with the current array. For tax filers who simply take the standard deduction and personal exemptions, the following tax rates hold.

For single taxpayers:

Nominal Income Total Income Payroll Tax Income Tax Total Tax Average Rate % Marginal Rate %
14500 15609 2219 1209 3427 22.0 28.1

5000000 5079122 158243 1726366 1884610 37.1 37.4

For a couple without children:

Nominal Income Total Income Payroll Tax Income Tax Total Tax Average Rate % Marginal Rate %
14500 15609 2219 720 2939 18.8 23.5
25000 26913 3825 1818 5643 21.0 28.1

5000000 5085743 171486 1717753 1889239 37.1 37.4

And for a family of four (with no child tax credits applied; I am not up to date on the latest law on this score):

Nominal Income Total Income Payroll Tax Income Tax Total Tax Average Rate % Marginal Rate %
14500 15609 2219 0 2219 14.2 14.2
25000 26913 3825 1040 4865 18.1 23.5
30000 32295 4590 1540 6130 19.0 23.5
40000 43060 6120 2973 9093 21.1 28.1
50000 53825 7650 4473 12123 22.5 28.1
60000 64590 9180 5973 15153 23.5 28.1
75000 80738 11475 8223 19698 24.4 28.1
100000 107650 15300 13713 29013 27.0 37.4
200000 215300 30600 40156 70756 32.9 40.2
300000 317593 35186 71963 107149 33.7 35.4
500000 520493 40986 140198 181184 34.8 37.4
1000000 1027743 55486 315198 370684 36.1 37.4
2000000 2042243 84486 665198 749684 36.7 37.4
5000000 5085743 171486 1715198 1886684 37.1 37.4

As we can see, the marginal rates get up to 28% rather quickly, and peak at a bit over 37%. Dick Armey’s call for a 17% flat tax is a huge giveaway to the rich compared to current law.

I crafted a flat 40% tax plan which merged all these taxes which comes out as a tax cut for everyone short of around $200K/year/individual by having a $12,000/year prebate. Not sure how this would come out for the treasury, but if we count the prebate against all welfare and Social Security benefits, we could get most people off those other programs.

Of course, those who game the system pay less than the rates above. For example, state income taxes alone take many high income earners above the standard deduction. Throw in mortgage interest and property taxes and my estimate for the professional class (doctors, lawyers, full professors, engineers, etc.) is low. Furthermore, pay in the form of health insurance is not taxed. (Or is that was? I am not up on the details of Obamacare.) And professional class workers can defer income through 401(k) plans, HSAs, etc.

So my evil plan may be a wash for professionals. But even if it is a wash monetarily, it eliminates the need to play the government’s game to keep your cash. Those who want to save to start a business instead of save for retirement. We could expect a mini boom in entrepreneurship. Furthermore, employing others would much easier. One simple tax to collect. Multiply by 0.4 and send it in.

What think ye?
