KPMG has released its annual survey of personal income tax rates around the world. The survey covers 86 countries, including all the high-income nations and many middle- and lower-income nations, such as Brazil, China, and India.

The chart shows the top personal income tax rates in 2009 for national governments, per the KPMG study. The current top U.S. rate is 35 percent, which is substantially above the 86-country average of 28.9 percent. The Obama administration plans to let the U.S. rate jump to 39.6 percent in 2011, which would be almost 11 points higher than the international average.

Worse still, the United States has state income taxes with rates up to 10 percent that are piled on top of the federal tax. Some of the nations in the survey (e.g. Canada) also have subnational income taxes, but many, or most, of them do not.

Finally, note that supporters of government health care expansion have been eyeing further increases in the top U.S. tax rate above 40 percent. Alas, we need more of the Global Tax Revolution to sweep across our shores.
