Be sure to read the whole piece, if for no other reason than to access the tables. The money quotes come in the last paragraph, which I’ve not quoted here.
“During my recent testimony before the Senate Budget Committee (found here), I cited an OECD statistic that the U.S. has the most progressive income tax system among industrialized nations.[1] This prompted one Senator to point out that if the richest 10% of taxpayers earn the most of any OECD country, shouldn’t it make sense that they bear the largest tax burden of any country?
The answer can be found in the OECD table below. This table shows the share of taxes paid by the richest 10 percent of households, the share of all market income earned by that group, and the ratio of what that 10 percent of households pays in taxes versus what they earn as a share of the nation’s income.
The first column shows that the top 10 percent of households in the U.S. pays 45.1 percent of all income taxes (both personal income and payroll taxes combined) in the country. Italy is the only other country in which the top 10 percent of households pays more than 40 percent of the income tax burden (42.2%). Meanwhile, the average tax burden for the top decile of households in OECD countries is 31.6 percent.
By contrast, column #2 shows that the richest decile in America earned 33.5 percent of the market income in the country in 2005 – the year in which this snapshot was taken, but little has changed since then. But, a few other countries do have a greater or similar concentration of income as does the U.S. For example, the OECD table shows that the wealthiest decile of households in Italy and Poland earn a greater share of their country’s market income than do our “rich” – 35.8 percent and 33.9 percent respectively – while the share of income earned by the top decile of households in the U.K. is about on par with those in the U.S. at 32.3 percent.”
