The Top 1% of Taxpayers Paid More in Federal Income Taxes in 2006 Than the Entire Bottom 95%
In 2002, before most of the "tax cuts" went into effect, the share of income taxes paid by the top 1% was below 34%, and by 2006 that share increased to almost 40%. If we assessed tax policies by the share of income taxes paid by "the rich" (i.e. top 1%), the "Jobs and Growth Tax Relief Reconciliation Act of 2003" wasn't a tax cut, it was a tax increase, since it increased the tax burden on the top 1% to record levels (40%), and resulted in more tax revenue from the top 1% than the entire bottom 95% of taxpayers!
Now, it's also true that the share of adjusted gross income earned by the top 1% has increased over time, while the share of income earned by the bottom 95% has decreased (see chart below), although the income share of the top 1% has been fairly stable at around 20% for the last ten years.
