Frictions as a Constraint on Tax Planning

Abstract

In recent years, the government has enacted a series of narrow tax reforms targeting specific planning strategies. Sometimes these reforms stop the targeted planning, but sometimes they merely prompt a new, more wasteful variation. The difference often lies in so-called frictions, which are constraints on tax planning other than the tax law, such as fees, accounting or regulatory treatment, credit risk, and the like. While frictions are important, reformers often lack key information, and legal academics should help provide it. This Article offers general observations about frictions that deter end runs. Most promising are strong "discontinuous" frictions that impose significant costs when taxpayers depart, even in subtle ways, from the transaction covered by the reform. Costs of relying on frictions are also considered, including information costs and distributional effects. Two case studies also are offered involving tax-motivated use of derivative financial securities. These reforms use essentially the same statutory language, but taxpayers have responded differently - and frictions explain this difference. The first reform, the "constructive sale" rule of Section 1259, targets use of derivatives in effect to sell an appreciated asset without paying tax. The second, the "constructive ownership" rule of Section 1260, targets use of derivatives in effect to invest in a hedge fund (or other pass-through entity) without the usual adverse tax consequences (i.e., less deferral and a higher tax rate). Theoretically, taxpayers can avoid either rule through relatively modest changes in the derivative's economic return. This strategy is commonly used to avoid Section 1259, a reality that was understood by government and taxpayers alike when the measure was enacted. In contrast, this strategy is not commonly used to avoid Section 1260. The difference, which was not well understood by Section 1260's drafters, is that securities dealers cannot supply the derivative that theoretically avoids the rule.
