I just finished my Federal taxes for 2012 .....

56. My numbers in your format

And here are the effective tax rates:
Tax on Total Income: 20.8%
Tax on Adjusted Gross Income: 20.8% (I don't have any adjustments)
Tax on Taxable Income: 23.3%

Those numbers, based on the Form 1040, come from:

1) Line 61 / Line 22 (Total Tax / Total Income)
2) Line 61 / Line 37 (Total Tax / Adjusted Gross Income )
3) Line 61 / Line 43 (Total Tax / Taxable Income)

I was subject to the Alternative Minimum Tax this year. My AGI was down 36.7% from last year.

I am not retired. I'm in my prime earning years (late 40s). I'm very happy with my income and not bothered at all by my tax rates. Of course, I take advantage of many tax breaks to minimize my tax rate. In the last year, I converted money from an IRA to a Roth IRA, made contributions to a 401K, made contributions to a pension, received pre-tax health/dental/vision insurance, received a pre-tax life insurance benefit, contributed to a 529 college savings plan, and contributed to a Health Savings Account.

I still don't know how this would compare to a "1%er". I'm sure that if I looked at the comparable numbers on their tax form, it would look like they paid an even higher rate. I'm just as sure that the reality would be different because they would have done even more to avoid having income show up as income from tax purposes. So if I looked at Mitt Romney's final Form 1040 and compared the same lines, it would look like he was paying a really high tax rate, but the reality is that he is probably paying much, much less.
