It depends on how you define the tax rate:
Historically, the term “tax rate” has meant the average or effective tax rate — that is, taxes as a share of income. The broadest measure of the tax rate is total federal revenues divided by the gross domestic product.
By this measure, federal taxes are at their lowest level in more than 60 years. The Congressional Budget Officeestimated that federal taxes would consume just 14.8 percent of G.D.P. this year. The last year in which revenues were lower was 1950, according to the Office of Management and Budget.
Yet if one listens to Republicans, one would think that taxes have never been higher, that an excessive tax burden is the most important constraint holding back economic growth and that a big tax cut is exactly what the economy needs to get growing again.
The G.O.P. says global competitiveness requires the United States to reduce its corporate tax rate. But the United States actually has the lowest corporate tax burden of any of the member nations of the Organization for Economic Cooperation and Development.
So, how do Republicans get away with claiming that historically low tax rates are the opposite?
… They do so by ignoring the effective tax rate and concentrating solely on the statutory tax rate, which is often manipulated to make it appear that rates are much higher than they really are.
For example, Stephen Moore of The Wall Street Journal recently asserted that Democrats were trying to raise the top income tax rate to 62 percent from 35 percent. But most of the difference between these two rates is the payroll tax and state taxes that are already in existence. The rest consists largely of assuming tax increases that no one has formally proposed and that would be politically impossible to enact at the present time.
Nevertheless, one routinely hears variations of the Moore argument from conservative commentators. By contrast, one almost never hears that total revenues are at their lowest level in two or three generations as a share of G.D.P. or that corporate tax revenues as a share of G.D.P. are the lowest among all major countries. One hears only that the statutory corporate tax rate in the United States is high compared with other countries, which is true but not necessarily relevant.
The economic importance of statutory tax rates is blown far out of proportion by Republicans looking for ways to make taxes look high when they are quite low. And they almost never note that the statutory tax rate applies only to the last dollar earned or that the effective tax rate is substantially lower even for the richest taxpayers and largest corporations because of tax exclusions, deductions, credits and the 15 percent top rate on dividends and capital gains.
The many adjustments to income permitted by the tax code, plus alternative tax rates on the largest sources of income of the wealthy, explain why the average federal income tax rate on the 400 richest people in America was 18.11 percent in 2008, according to the Internal Revenue Service, down from 26.38 percent when these data were first calculated in 1992. Among the top 400, 7.5 percent had an average tax rate of less than 10 percent, 25 percent paid between 10 and 15 percent, and 28 percent paid between 15 and 20 percent.
The truth of the matter is that federal taxes in the United States are very low. There is no reason to believe that reducing them further will do anything to raise growth or reduce unemployment.
Meanwhile, back at the jobs and foreclosure crisis (emphasis is mine):
U.S. single-family home prices dropped in March, dipping below their 2009 low, as the housing market remained bogged down by inventory and weak demand, a closely watched survey said Tuesday.
But don’t forget: The economic priority is to cut spending. Remember: Home prices dipping below historic levels, foreclosures increasing, and jobs disappearing does not constitute an emergency. The deficit does. Because… well, because it’s crushing us. Because we are burdening our grandchildren with mountains of debt. As opposed to crushing our families and burdening our children with more foreclosures and a weakening housing market added to a grim employment outlook. How could anyone make a rational case that the burden to our current economy and to our currently living children with the immediate consequences of millions of Americans with no job, no prospect of a job, no home, and no income is a more immediate threat to the health of an economy than raising the national debt ceiling would be? Beats me. I guess you have to be a loony liberal to understand that one.
