EFFECT OF REAGAN, KENNEDY, AND BUSH TAX CUTS ON REVENUES
EFFECT OF REAGAN TAX CUTS ON REVENUES - SHORT ANALYSIS
The argument that the near-doubling of revenues during Reagan's two terms proves the value of tax cuts is an old argument. It's also extremely flawed. At 99.6 percent, revenues did nearly double during the 80s. However, they had likewise doubled during EVERY SINGLE DECADE SINCE THE GREAT DEPRESSION! They went up 502.4% during the 40's, 134.5% during the 50's, 108.5% during the 60's, and 168.2% during the 70's. At 96.2 percent, they nearly doubled in the 90s as well. Hence, claiming that the Reagan tax cuts caused the doubling of revenues is like a rooster claiming credit for the dawn.
Furthermore, the receipts from individual income taxes (the only receipts directly affected by the tax cuts) went up a lower 91.3 percent during the 80's. Meanwhile, receipts from Social Insurance, which are directly affected by the FICA tax rate, went up 140.8 percent. This large increase was largely due to the fact that the FICA tax rate went up 25% from 6.13 to 7.65 percent of payroll. The reference to the doubling of revenues under Reagan commonly refers to TOTAL revenues. These include the above-mentioned Social Insurance revenues for which the tax rate went UP. It seems highly hypocritical to include these revenues (which were likely bolstered by the tax hike) as proof for the effectiveness of a tax cut.
Hence, what evidence there is suggests there to be a correlation between lower taxes and LOWER revenues, not HIGHER revenues as suggested by supply-siders. There may well be valid arguments in favor of tax cuts. But higher tax revenues does not appear to be one of them.
EFFECT OF BUSH TAX CUTS ON REVENUES AND GDP
There have been three major tax cuts under Bush. Briefly, the 2001 tax cut created a new 10% individual tax rate and phased in the lowering of individual tax rates. It also phased in an increase in the child tax credit, marriage penalty relief provisions, an increase of the estate tax exemption, an increase in the IRA contribution limit, and the repeal of limits on itemized deductions and personal exemptions. The 2002 tax cut was chiefly aimed at business, creating 30% expensing for certain capital asset purchases, extending the exception under Subpart F for active financing income, and increasing the carryback of net operating losses to 5 years. Finally, the 2003 tax cut lowered the top individual income tax rate on dividends and capital gains and accelerated most of the phased-in provisions of the 2001 tax cut. For a more complete description of the tax cuts, see page 14 of Revenue Effects of Major Tax Bills.
As mentioned above, the real growth in individual income tax receipts was 5.77% from 1998 to 2008 and -19.36% from 1999 to 2009. These are the lowest growth rates of any of the 60 10-year spans from 1940 to 2009. However, these two spans begin before the initial Bush tax cut in 2001. Hence, it may be better to look at a shorter time-span to try to judge the effects of the Bush tax cuts. A good choice might be eight years as this would cover the span from the year of Clinton's last budget (2001) to the last year for which there is actual data (2009). The growth of receipts by source, outlays, and GDP over every 8-year period since 1940 is shown in the following graph:

The actual numbers and sources can be found at recgro8y.html. As can be seen in the second table and graph, real individual income tax receipts declined 25.06% from 2001 to 2009. Even total receipts declined -13.93% over that period. Finally, real GDP grew just 13.36% from 2001 to 2009. This was the lowest real GDP growth over any 8-year span since 13.33% from 1966 to 1976. Hence, although it's been just about eight years since the 2001 tax cut and six years since the 2003 tax cut, the evidence to this point is that the Bush tax cuts decreased revenues over what they would have been, at least over the short term. This was true even in my prior analysis based on data through 2007, before the financial crisis of 2008.
