Buffett Rule

[7] A White House statement released in January 2012 defined the rule as part of "measures to ensure everyone making over a million dollars a year pays a minimum effective tax rate of at least 30 percent ... implemented in a way that is equitable, including not disadvantaging individuals who make large charitable contributions.

[8] The United States Congress Joint Committee on Taxation released a letter in March 2012 estimating that the Buffett Rule would raise $46.7 billion over the next decade.

For example, the Joint Committee on Taxation assumes that many high-income taxpayers would reduce the amount of capital gains realized in one year to fall beneath the Buffett Rule threshold.

[18] The Joint Committee on Taxation calculated that the Buffett Rule plus the repeal of the Alternative Minimum Tax would increase the deficit by $793.3 billion in the next decade.

[19] The $793.3 billion loss projected did not take into account additional proposed measures, such as incremental increases in retirement age and payroll tax lifetime contributions raised to $190,000 by 2020, about $22,000 higher than it would be under current law.

An October 2011 study by the Congressional Research Service found that a 30% minimum tax rate rule would mean up to 200,000 taxpayers, equivalent to 0.06% of all U.S. citizens, paying more.

[14] Paul Krugman, The New York Times columnist and Nobel Prize–winning economist, wrote in January 2012 that "such low taxes on the very rich are indefensible".

[23] A CBS News/The New York Times poll released in January 2012 found that 52 percent of Americans agreed that investments should be taxed at the same rate as income.
