Alan Reynolds On The Problems Of High Taxes

See Obama's Soak-the-Rich Tax Hikes Won't Work: Income tax revenues have been remarkably stable at 8% of GDP, regardless of tax rates. The way to increase revenue is to grow the economy from the 4-14-11 WSJ. Excerpts:

"The individual income tax brought in 7.8% of GDP from 1952 to 1979 when the top tax rate ranged from 70% to 92%, 8% of GDP from 1993 to 1996 when the top tax rate was 39.6%, and 8.1% from 1988 to 1990 when the highest individual income tax rate was 28%. Mr. Obama's hope that raising only the highest tax rates could keep individual tax receipts well above 9% of GDP has been repeatedly tested for more than six decades. It has always failed.

Federal revenue from the individual income tax exceeded 9% of GDP only eight times in U.S. history—during World War II (9.4% in 1944), the recessions of 1969-70, 1981-82 and 1991-92, and the tech-stock boom-bust of 1998-2001. Revenues were a high share of GDP during the three recessions because GDP fell.

The situation of 1997-2000 was unique. Individual income tax revenues reached an unprecedented 9.6% of GDP from 1997 to 2000 for reasons quite unlikely to be repeated. An astonishing quintupling of Nasdaq stock prices coincided with an extraordinary proliferation of stock options, which the Federal Reserve's Survey of Consumer Finances found were granted to 11% of U.S. families by 2001, and with a reduction in the capital gains tax to 20% from 28%, which encouraged much greater realization of taxable gains through stock sales. Revenues from the capital gains tax rose to 10.8% of all individual income tax receipts in 1997 and 13% by 2000. The unexpected revenue windfalls in President Bill Clinton's second term were largely a consequence of lower tax rates on capital gains.

Using IRS data, Thomas Piketty of the Paris School of Economics and Emmanuel Saez of the University of California at Berkeley have estimated that realized capital gains accounted for just 13%-22% of reported income among the top 1% of taxpayers from 1988 to 2006, when gains were taxed at 28%—but that fraction swiftly reached 29%-32% in 1998-2000, when the capital gains tax fell to 20%.

The average tax rate of such top taxpayers was mechanically diluted by the greatly increased realizations of capital gains after 1997 and 2003, since a larger share of reported income consisted of capital gains. Yet the amount of taxes paid by top taxpayers reached record highs for the same reason—there was more revenue to be had from taxing many gains at a low rate than from taxing fewer gains a high rate. Nobody can be forced to sell assets in taxable accounts. To complain that a low tax on realized capital gains is "unfair" is to suggest it would be fairer for affluent investors to sit on unrealized gains, as though an unpaid tax is morally superior to one that collects billions."

"Among the top 400 taxpayers (rarely the same people from one year to the next), the average tax rate fell to 22.3% in 2000, when the capital gains tax was 20%, from 29.9% in 1995 when the capital gains tax was 28%. But that same IRS report also shows that real tax revenues from the top 400 more than doubled after the capital gains tax fell, rising to $11.8 billion in 2000 from $5.2 billion in 1995, measured in 1990 dollars.

The same thing happened after 2003, when the capital gains tax was further reduced to 15%. The average tax rate of the top 400 fell to 16.6% in 2007 from 22.9% in 2002. Even though there was no stock market boom as in 1997-2000, real revenues of the top 400 nevertheless doubled again—to $14.5 billion in 2007 from $6.9 billion in 2002. Instead of paying less when the capital gains tax rate went down in 1997 and 2003, the top 400 instead paid much, much more."
