The idea of increasing revenue without raising rates is not new. It was implemented years ago when Congress placed a phase-out, which is a type of cap, on the personal and dependency exemption deduction and on select itemized deductions. The reason was an amazing bit of political manipulation. In Objections Raised to Elimination of Legislative Tax Deceit, I explained the background of this maneuver:
These two phaseouts [on itemized deductions and the deduction for personal and dependency exemptions] were enacted in 1990 as part of a Congressional subterfuge, or deceit, foisted upon the American citizenry. When public officials deceive citizens, problems arise. In this particular instance, Congress wanted to raise taxes without raising tax rates, because it concluded that it could tell Americans that it did not raise taxes by pointing to unchanged tax rates. However, "clever" minds figured out that if deductions, in this case itemized deductions and the deduction for personal and dependency exemptions, were reduced, the effect would be an increase in tax revenues. In other words, Congress "discovered" that it could raise taxes without raising tax rates and thus trumpet a self-serving proclamation that it had not raised taxes. The simple word for this is lying.I revisited the issue in When is a 15% Tax Rate Not a 15% Tax Rate?, in which I noted:
I wrote about this problem 16 years ago, in Getting Hamr'd: Highest Applicable Marginal Rates That Nail Unsuspecting Taxpayers, 53 Tax Notes 1423 (1991). It has been cited and quoted almost a dozen times. I doubt, though, that anyone in Congress has read it. That's too bad, because repairs could be made if members of Congress understood the wool that was pulled over their eyes and the eyes of the citizenry by the folks who shoved phaseouts into the tax law as a way of raising taxes without raising rates.When comparing the two approaches, I see only one advantage to the use of phase-outs, including deduction caps. Deduction caps permit legislators to claim that they have not raised tax rates, hoping that people interpret this claim as equivalent to not raising taxes. It is a misleading approach.
In contrast, I can identify more than a few disadvantages to using deduction caps. Each one by itself outweighs the seeming advantage. Because deduction caps are like phase-outs, the disadvantages of phase-outs that I examined in detail in Objections Raised to Elimination of Legislative Tax Deceit are no less applicable to deduction caps. I highlight these disadvantages, and others, in the following list.
First, deduction caps, like phase-outs, distort the progressivity of the income tax by creating higher average marginal tax rates for taxpayers not at the top of the income pyramid than apply to those at the top of the income pyramid. If nominal marginal tax rates have as much impact on economic decision making as tax-rate reduction advocates claim, average marginal tax rates have at least as much impact, and the skewing of those rates by the use of deduction caps is not beneficial.
Second, deduction caps, like phase-outs, complicate the tax law. The complication is unwarranted, detrimental, and cost-ineffective. The complication increases the chances of errors on tax returns.
Third, deduction caps, like phase-outs, do not increase tax revenue from all high-income taxpayers. Caps only affect those high-income taxpayers who claim the deductions that are subject to a cap.
Fourth, deduction caps, like phase-outs, do nothing to close the many loopholes used by high-income taxpayers to reduced their effective income tax rates, because most of those loopholes do not involve deductions.
Fifth, a deduction cap on the charitable contribution deduction probably will cause a reduction in charitable contributions by high-income taxpayers. In the long run, this outcome is much more harmful to the economy than raising tax rates.
Sixth, deduction caps, like phase-outs, exacerbate the marriage penalty. There are enough challenges with trying to eliminate that penalty without creating a penalty on unmarried individuals without making the task even more daunting.
Seventh, a deduction cap does absolutely nothing to stop the revenue losses arising from absurdly low tax rates on capital gains and qualified dividends. The current capital gains rates are much lower than they need to be to offset the inflation impact that serves as the justification for the lower rates.
About a year and a half ago, in A Foolish Tax Idea Resurfaces, I criticized the President for including a deduction phase-out in his fiscal year 2012 budget proposal. Apparently the President has seen the light, and according to this story, is rejecting deduction caps in favor of the much more transparent tax rate cut expiration. Two years earlier, in a Tax Change Ought Not Be Tax Redux, I criticized the President’s fiscal year 2010 budget proposal for suggesting that the itemized deduction and personal and dependency exemption phase-outs ought to be restored.
As explained in Objections Raised to Elimination of Legislative Tax Deceit, I successfully campaigned against the phase-outs and they were recently phased out of the tax law. It would be a step backwards to reinstate them, to let them be reinstated through inaction, or to adopt their deduction cap surrogates.
There are better solutions. Replacing deductions with credits is one. Repealing the special capital gains rates and indexing adjusted basis for inflation is another. Restoring progressivity to the tax law to undo a decade’s worth of economic damage caused by the discredited “trickle down” theory is yet another. Repealing special interest deductions is still another. It is time to start talking about genuine cures rather than playing around with attempts to hide the problems and mask the solutions. As I wrote in Tax Change Ought Not Be Tax Redux, “Let's face it. The days of using Pease and PEP to hide tax increases are long gone. Everyone knows the score. Aside from the impropriety of raising taxes using clandestine gimmicks, there's no need to do so. There's no genuine impediment to doing what needs to be done in the way it needs to be done. The bleating from the privileged few that taking away their capital gains break or their special dividend rate will destroy the economy should fall on deaf ears. The special interest groups have cried wolf too many times.”
