In an order released in July 2021, the Illinois Tax Tribunal denied a taxpayer’s motion for summary judgment in a “unitary business” case, finding that there were disputed issues of fact as to whether the taxpayer was engaged in a unitary business with a company that the taxpayer sold. See Christopher v. Illinois Dep’t of Rev., 19 TT 131 (Ill. Tax Trib. Nov. 24, 2020, released July 2021). The taxpayer, T. Christopher Holding Company (“Holding Company”), claimed that it was not unitary with Vogue International, LLC (“Operating Company”), and thus its gain from the sale of Operating Company could not be included in Holding Company’s Illinois business income under U.S. constitutional principles and Illinois law. However, the Tribunal found that the Illinois Department of Revenue (“Department”) had presented sufficient evidence to establish a disputed issue of material fact that rendered summary judgment on this issue inappropriate.
