Limit Tax Expenditures

The National Tax Journal asks for views on a recent proposal from Len Burman to limit tax expenditures. My answer: I couldn’t agree more.

With regard to the politics, one would have to see whether the phrase “cut tax expenditures” polls more like the phrase “cut expenditures,” which I assume polls well, or like the phrase “raise taxes,” which of course polls horribly.  I have no idea.  But at least there is a hope of breaking through the mindless artificial “Taxes versus Spending” rhetoric that dominates Washington.

With regard to the merits of the idea as economic policy — in a context where strong measures to reduce the budget deficit will be necessary in coming years — Burman is completely right.   Most tax expenditures tend by nature to be distortionary.   Many of them are convoluted ways of making what would otherwise be a subsidy look like a tax deduction.

Agreeing to the general principle of limiting tax expenditures is easier than agreeing to all the detailed implications.   Looking at the list of the actual 12 largest tax expenditures would give most people pause.   But much less so for economists.    The only one on the list that gives me serious pause, personally, is #7:  the “charitable deduction (other than education and health).”   But the top two deserve to be cut, as part of a larger fiscal package, not just because they would save a lot of money, but also to get economic incentives right.  Those top two are the exclusion for employer-sponsored health insurance and the mortgage interest deduction.

A proposal to eliminate the mortgage interest deduction would of course get zero support in Congress, because it is political suicide with middle class voters.   A more moderate proposal to freeze the amount of the deduction would also be unpopular.  The same with four other pro-housing tax expenditures out of Len’s list of 12:    deduction for property taxes, exclusion of net imputed rental income, capital gains exclusion on home sales, and property tax deduction.   All politicians and voters (excluding economists) continue to believe that public policy should tilt in favor of home ownership.   Notwithstanding the recession that began with the sub-prime mortgage crisis of 2007, economists have not made even a dent in popular perceptions, with our arguments against artificially tilting the field away from rental housing and the rest of the capital stock, which is what you do when you tilt toward owner-occupied housing.   That the bias is toward high leverage in home ownership makes it worse.  To take another example, whatever happens ultimately to Fannie Mae and Freddie Mac, they certainly won’t be abolished.    Americans believe too strongly in the dream of home ownership to absorb fully the point that you are not doing a family a favor if getting them into their own house means burdening them with debt that they will probably not be able to repay.

“Political impossibility” is not a reason not to try.  After all, our country will not get through the next few decades, fiscally, unless we make some “politically impossible” changes.   But I emphasized the housing issue in the preceding paragraph to make a different point.   Almost all commentators on the financial crisis, whether from the left or right, talk as if the causes of the crisis are obvious and our leaders are idiots for not having acted to fix the problem ahead of time.  Needless to say, those on the left blame the right, for deregulation, and those on the right blame the left, for moral hazard.   And yet there is still zero support for fixing the housing policy parts of the problem, on which economists have almost unanimous agreement (and did ahead of the crisis).

The Mortgage Interest Tax deduction not only helped fuel the housing bubble, but more importantly it’s the cause of impossible-to-value toxic assets (MBS). The tax deduction allows people to borrow money cheaply, which is an incentive to keep it for a long time. We’re one of only a few countries with 30 year mortgages, thanks to the deduction. The deduction must be ended to restore fiscal health. As for political support, yes it’s controversial, but the majority of Americans don’t benefit from it. In fact they subsidize it. http://decouple.org/the-news/54-end-mitd

Why the interest rate tax deduction? Promote home ownership, there use to be deductions for second homes and interest on credit cards I believe. Lets face it, no matter how much revenue comes in it will never be enough! At the rate we are going I think it is best if the we go bankrupt.I read the columns on this blog written by highly educated people and I am amazed how small their ideas are.
