US Tax Revenues

I saw a post from one of my friends the other day, talking about relief for individual taxpayers.  I found the following graph on Wikipedia which shows the percentage of tax revenues from various sources.  It’s interesting the taxes from individuals have remained relatively flat at 40% over the past 60 years.  Tax receipts from corporations, on the other hand, have declined over this same period of time.  Payroll taxes which are partially paid by individuals and partially by corporations have increased dramatically.  Without a doubt individual taxpayers carry the lion’s share of the US tax burden.
