Today, the U.S. Supreme Court issued its decision in South Dakota v. Wayfair, overturning Quill Corp. v. North Dakota, 504 U. S. 298 (1992) and National Bellas Hess, Inc. v. Department of Revenue of Ill., 386 U. S. 753 (1967), that required businesses to have a physical presence in a taxing jurisdiction in order to create nexus for sales and use tax purposes. The Court, overturning its own precedent, held that those cases were “unsound and incorrect.”  Additionally, the Court implied with this decision that its prior jurisprudence on the dormant Commerce Clause may be questioned.[1]
