Duquesne Light Holdings Inc v. Commissioner of Internal Revenue, No. 14-1743 (3d Cir. 2017)Annotate this Case
The Duquesne entities filed tax returns as a consolidated taxpayer, which requires a mixed approach: calculating some aspects of the group’s taxes as though the entities were a single taxpayer and calculating others as if each were a separate taxpayer, 26 U.S.C. 1502. There is, nonetheless, the potential for the group to deflect its tax liability by using stock sales to claim a “double deduction” for a single loss at a subsidiary. In 2001, the Federal Circuit invalidated Treas. Reg. 1.1502-20, which prevented double deductions when the parent’s loss on its sale of stock occurred before the subsidiary recognized its loss, leaving intact the regulatory prohibition on double deductions where the transactions are structured so that the losses occur in reverse order. Duquesne group then arranged a series of transactions, so that on its 2001 tax return, it carried back $161 million of loss and claimed a tentative refund of $35 million. In 2002 the IRS issued temporary regulations that applied to stock losses occurring on or after March 7, 2002. Duquesne group incurred further stock losses in transactions after March 2002. The IRS determined that it had claimed a double deduction and disallowed $199 million of these losses under the Ilfeld doctrine, that the Code should not be interpreted to allow the taxpayer the practical equivalent of a double deduction absent a clear declaration of intent by Congress. The Tax Court granted the IRS summary judgment. The Third Circuit affirmed, concluding that the Ilfeld doctrine remains good law.
