New data from the IRS show that in 2007 the richest 400 taxpayers in America increased their incomes by 31 percent over the previous year, increased their share of total income in America, and paid an even lower effective tax rate than ever before.
Writing for Tax Analysts, David Cay Johnston finds that the average income of the richest 400 grew from $263.3 million in 2006 to $344.8 million in 2007. Meanwhile, their effective income tax rate fell from 17.17 percent in 2006 to 16.62 percent in 2007.
As usual, a major cause of the low effective tax rates is the preferential rate for capital gains and stock dividends, which are taxed at a top rate of 15 percent instead of the top rate of 35 percent that applies to other income for the very rich. Capital gains made up 66.3 percent of income for the top 400 in 2007, up from 62.8 percent in 2006.
The data seem to highlight the need to allow the Bush tax cuts, which cut the top rate for capital gains and stock dividends to 15 percent, to expire as scheduled at the end of 2010.
The report released last week by Citizens for Tax Justice on the President's budget argued that Congress should at least allow the Bush tax cuts to expire for the rich (which Obama defines as married couples with incomes above $250,000 and unmarrieds with income above $200,000) and should enact at least as many revenue-raisers as the President proposes.
