South Dakota v. Wayfair
Background
On June 21, 2018, The United States Supreme Court ruled 5-4 in South Dakota v. Wayfair that states can mandate that businesses without a physical presence in a state with more than 200 transactions or $100,000 in-state sales collect and remit sales taxes on transactions in the state. This decision overturned the Court’s 1992 decision in Quill v. North Dakota and 1967 decision in National Bellas Hess. Since the decision was handed down by the Court, states and retailers alike have been asking “What’s next?”
