This Article will address tax law's inconsistent treatment of gains and losses-focusing in particular on certain instances in which a taxpayer is prevented from shifting a built-in loss to another taxpayer but would be allowed to shift a built-in gain to another taxpayer. The article will explore whether any legitimate justification can explain the inconsistency. Finding no such legitimate justification for at least some of the examples, this Article will conclude that lawmakers ought to have also addressed gains and the failure to do so results from lawmakers crafting an overly narrow response that addressed only the most recent, high-profile gimmick in engineering transactions to reduce tax liability.
