The Internal Revenue Service tracks the tax returns with the 400 highest adjusted gross incomes each year. The average income on those returns in 2007, the latest year for IRS data, was nearly $345 million. Their average federal income tax rate was 17 percent, down from 26 percent in 1992.
Over the same period, the average federal income tax rate for all taxpayers declined to 9.3 percent from 9.9 percent.
The top income tax rate is 35 percent, so how can people who make so much pay so much less than that in taxes? The nation’s tax laws are packed with breaks for people at every income level. There are breaks for having children, paying a mortgage, going to college, and even for paying other taxes. Plus, the top rate on capital gains is only 15 percent.
