An Instance Where the Business Taxpayer Can Win Despite the Absence of Economic Substance !!! In Summa Holdings Inc. v. Commissioner, No. 16-1712 (Feb. 16, 2017), the Sixth Circuit Court of Appeals reversed the Tax Court decision below which held that payments a corporation made to a DISC were not DISC commissions but instead were to be characterized as dividends to shareholders followed by excess contributions to their Roth IRAs. Such recharacterization would have eliminated the tax benefits associated with the IC-DISC for the taxpayers.
