Every year at this time, the Congressional Budget Office issues an interesting report on taxable income and federal taxes paid. It doesn't seem to attract much attention. Maybe we're just used to hearing how concentrated income -- and, in particular, income-producing wealth -- is in America. Maybe it just conflicts with our notions of "created equal" and "equal opportunity" and "equal liberty," and, not knowing how to deal with the reality, we skip over it.
But here it is. The report is at http://www.cbo.gov/ftpdocs/100xx/doc10068/effective_tax_rates_2006.pdf and historical data is at http://www.cbo.gov/publications/collections/taxdistribution.cfm The first report is short -- 5 pages with 2 tables (one for 2006, the other for 2005 -- 3 panels to each).
Here are some highlights.
1. The average federal tax rate, including individual income taxes, was 20.7% in 2006. That is composed as follows:
9.1% | individual income taxes |
7.5% | social insurance taxes |
3.4% | corporate income taxes |
20.7% | total federal taxes |
source: Table 1, Panel A, 6th column. |
2. While the average federal tax rate is 20.7%, the average tax rates within quintiles are as follows
average federal tax rate |
|
bottom 20% of us | 4.3% |
second 20% | 10.2% |
middle quintile | 14.2% |
fourth quintile | 17.6% |
only in the highest quintile does the overall federal tax rate exceed the "average" |
25.8% |
3. Within the top quintile, the table provides these data:
average federal tax rate |
|
top 10% of us |
27.5% |
top 5% | 29.0% |
top 1% | 31.2% |
4. I did a bit of spreadsheet work, and broke out the quantiles, which yields a very different picture from what the preceding four data points might suggest:
average federal tax rate |
|
top 1% of us |
31.2% |
next 4% | 25.6% |
next 5% | 22.5% |
next 10% | 20.8% |
5. Individual income taxes, so much on the minds of some of us at this time of year, represented 9.1% of income, or about 20% more than the 7.5% that social insurance taxes represented in aggregate. But only in the highest quintile do individual income taxes exceed social insurance taxes. [Table 1, fifth data column, 2nd and 3rd rows.]
6. Distribution of income and of taxes:
percent of pretax income |
percent of federal taxes |
percent of after-tax income |
percent of social insurance taxes |
|
top 1% of us | 18.8% | 28.3% | 16.3% | |
next 4% | 13.1% | 16.4% | 12.2% | |
second 5% | 9.7% | 10.7% | 9.6% | |
second 10% | 14.1% | 13.9% | 14.0% | |
[There may be some rounding error in there somewhere.] | ||||
top 20% | 55.7% | 69.3% | 52.1% | 43.5% |
The bottom 80% of us received less than half the aggregate income. |
7. Social insurance taxes place a signficant burden on people in the bottom 4 quintiles. The figures incorporate both the employee's portion and the employer's portion.

The bottom 20% of us pay more in Social Insurance Taxes than do the top 1%, though the top 1% have average pretax income 100 times as high and aggregate income 4 times as high.
In 2006, the FICA wage limit was $94,200. So the second pair of data columns suggests the distribution of wage income below $94,200.
7. Table 1, Panel 2 shows that 57.7% of capital income flows to the top 1% of us; a bit of spreadsheet work shows that 16.4% flows to the next 4% of us; 7.0% to the second 5% of us, and 6.7% to the second 10% of us; the top fifth of us gets 87.2% of that income. Remember that next time you hear about "Main Street" and "Small Business" as if they are enriching the middle class.
If we define the middle class as the middle 60%, we find that they have 41.8% of pretax income, 44.9% of aftertax income, pay 30.2% of taxes, and 52.7% of social insurance tax taxes
