New Reports Find Little Good News in Capital Gains Tax Rate Hike
Two new reports were released in the Capital Gains Series from the Institute for Research on the Economics of Taxation (IRET) sponsored by The Searle Freedom Trust. The papers in this series discuss the taxation of capital gains and use quantitative tools to examine the economic and budgetary consequences of changes in the capital gains tax rate.
In The Relationship Between Realized Capital Gains And Their Marginal Rate Of Taxation, 1976-2004, Ohio State University Professor Paul D. Evans of Ohio State University finds that taxpayers are still sensitive to the tax rate on capital gains, and would report fewer gains if the rate were raised. Based on 2004 data, the revenue maximizing tax rate may be just under 10%. Raising the capital gains tax rate from the current 15% to 20% or more would reduce federal capital gains tax revenue. Additional revenue would be lost from other parts of the income tax and from other federal taxes due to reduced investment, employment, and income. The optimal capital gains tax rate to maximize public welfare, and to help the federal budget, is surely closer to if not zero.
The second study, The Effect Of The Capital Gains Tax Rate On Economic Activity And Total Tax Revenue, concludes that the tax rate increases would not raise anticipated revenues. About 91% to 95% of the revenue gains expected from the imposition of the 20%, 24%, and 28% rates would be lost due to lower incomes. Instead of raising income tax revenue by $30.7 billion, $54.7 billion, or $77.5 billion, respectively, the net income tax increases would be only $2.5 billion, $2.9 billion, and $4.0 billion in the three cases.
Lower levels of output, payroll, and consumption would reduce payroll taxes, corporate income taxes, excise taxes, and tariff revenue, resulting in net revenue losses. There would be further revenue reductions due to the decline in the capital stock, which would decrease the amount of capital gains available to be realized. The combined revenue effect would be losses of $24.9 billion, $46.2 billion, and $64.8 billion in the three cases. Lower wage rates would reduce federal budget outlays, but the combined effect would be a significant increase in federal budget deficits. State and local government budgets would be similarly hurt.
This and our recent post on the CBO’s take on capital gains make a pretty compelling case for maintaining the current capital gains tax rate. Sadly, a plan on lower capital gains tax rates is noticeably absent from President Obama’s new plan to aid small businesses.





"...to marshal more venture capital for more new industries -- the kind of efforts that begin with a couple of partners setting out to create and develop a new product -- we intend to lower the maximum capital gains tax rate."
"The tax on capital gains directly affects investment decisions, the mobility and flow of risk capital from static to more dynamic situations, the ease or difficulty experienced in new ventures in obtaining capital, and thereby the strength and potential for growth of the economy."
