In September 2012, My Top Marginal Tax Rates Poster made it to the "Shortlist — Data Visualisation Category" The Information is Beautiful Awards!!
My popular Tax Rates poster which illustrates the top tax rate* over the last 95 years for individuals, corporations and capital gains from the sale of stocks or real estate. It gives you a historical overview of the different "income" taxes in the United States. The data for this poster is available at BuzzData.
*The top tax rate or marginal tax rate is the rate you pay on the “last dollar” you earn; but when you view the taxes you paid as a percentage of your income, your effective tax rate is less than your marginal rate, especially after you take into account the deductions and exemptions, i.e. income that is not subject to any tax.
