A Lower Corporate Tax Rate Increases Tax Revenues, Promotes Economic Growth

From Bloomberg Opinion, "Laffer Curve Pays Billions If Obama Just Asks" by Kevin Hassett:

The U.S. is about to have the highest corporate tax rate in the developed world because our competitors have noticed that revenue goes up as rates go down. Multinational corporations today nimbly move their profits to the friendliest environment, rewarding tax havens like never before.

It looks as if President Barack Obama and congressional Democrats are going to miss out on the single biggest policy opportunity for the U.S. this year because of their ideological resistance to the idea that lower rates can increase revenue, also known as the Laffer curve.***Corporate taxes “are the most harmful type of tax for economic growth,” according to a November 2010 report by the Organization for Economic Cooperation and Development.***The U.S. top corporate tax rate of 35 percent in 2010 was higher than all other OECD nations except Japan, which has embarked on a 5 percentage-point cut. The average rate in the OECD is 23.5 percent. Ireland’s rate is only 10.9 percent; Turkey’s is 13.1 percent.***The U.S. earns less federal corporate tax revenue, as a percentage of gross domestic product, than the average OECD country. Higher rates, lower revenue.

From 2000 through 2009, the U.S. average corporate tax revenue as a percentage of GDP was 2.06 percent, according to OECD data. The average for the rest of the OECD was almost a percentage point higher, at 3 percent.

In 2009, the U.S. ratio dropped to 1.64 percent. That year, the U.K., with a tax rate of 28 percent, raised 2.8 percent of GDP. South Korea raised 3.4 percent of GDP with a rate of 22 percent. Belgium raised 2.5 percent of GDP with a rate of 34 percent.

A number of studies have indicated that a Laffer curve exists for corporate taxes. One study I did with Alex Brill, looking at data for OECD countries from 2000 to 2005, found that the U.S. could maximize its tax revenue by cutting the top corporate rate 8.6 percentage points, to 26.4 percent.
