Tax reduction thus sets off a process that can bring gains for everyone, gains won by marshalling resources that would otherwise stand idle—workers without jobs and farm and factory capacity without markets. Yet many taxpayers seemed prepared to deny the nation the fruits of tax reduction because they question the financial soundness of reducing taxes when the federal budget is already in deficit. Let me make clear why, in today's economy, fiscal prudence and responsibility call for tax reduction even if it temporarily enlarged the federal deficit—why reducing taxes is the best way open to us to increase revenues. —President John F. Kennedy, Economic Report of the President, January 1963
If only more of today's leaders thought like JFK. Sadly, in the debate over whether to extend the 2001 and 2003 tax cuts, and if so whether the cuts should be extended to those people who are in the highest tax bracket, there is a false presumption that higher tax rates on the top 1% of income earners will raise tax revenues.
Anyone who is familiar with the historical data available from the IRS knows full well that raising income tax rates on the top 1% of income earners will most likely reduce the direct tax receipts from the now higher taxed income—even without considering the secondary tax revenue effects, all of which will be negative. And who on Earth wants higher tax rates on anyone if it means larger deficits?
Since 1978, the U.S. has cut the highest marginal earned-income tax rate to 35% from 50%, the highest capital gains tax rate to 15% from about 50%, and the highest dividend tax rate to 15% from 70%. President Clinton cut the highest marginal tax rate on long-term capital gains from the sale of owner-occupied homes to 0% for almost all home owners. We've also cut just about every other income tax rate as well.
During this era of ubiquitous tax cuts, income tax receipts from the top 1% of income earners rose to 3.3% of GDP in 2007 (the latest year for which we have data) from 1.5% of GDP in 1978. Income tax receipts from the bottom 95% of income earners fell to 3.2% of GDP from 5.4% of GDP over the same time period. (See the nearby chart).
