March 2008

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.

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.
