Top 400 Taxpayers: Income and Taxes Paid 1992-2005

This graph shows the average income reported to the IRS and the average taxes paid by the top 400, i.e. the 400 taxes returns with the highest adjusted gross income from 1992-2005. This does not represent not gains in the wealth of people like Bill Gates but instead shows the annual income of the superrich reported to the IRS. They accounted for 1.15% of total income reported in 2005, more than twice as large as their 0.49% share in 1995.

Federal Income Tax Rates by Household Income

I updated a previous graph, comparing the effective tax rates for the Federal Individual Income and Social Insurance (payroll) by adding Excise and Corporate Income. Additionally, I added the tax rates for the Top 1%. Note: the effective tax rate increases for both individual and corporate income the higher the household’s income, while the social insurance and excise tax rate decreases.

Tax Rates: Individual Income vs Social Insurance 2005

Inspired by the tax rate graph in my previous post, I created this graph comparing the effective tax rates for the Federal Individual Income tax and Social Insurance (payroll) tax by household quintile. The Earned Income Tax Credit accounts for the negative individual income tax rate for the lowest and second quintiles.

Historical Tax Rates by Income Group: Part 2

In an earlier post, I had a graph showing the Historical Tax Rates by Income Group using data from Pitketty & Saez. Here is another graph (found on Greg Mankiw’s Blog) which shows historical tax rates by income group but this time the data is from the Congressional Budget Office.

CBO total effective tax rate

Addendum 3/3/08
The large difference between the two graphs is due to the treatment of payroll taxes paid by employers and the corporate income tax. The Pitketty & Saez data assumes these taxes are actually paid by employees and stockholders but the CBO data in the above graph does not include them.
