Case Brief Summary & Legal Analysis
tl;dr: The Supreme Court overruled its prior decisions in Quill and Bellas Hess, eliminating the rule that a business must have a physical presence in a state to be required to collect and remit sales tax. Economic and virtual contacts with a state are now sufficient.
Legal Significance: This decision fundamentally altered dormant Commerce Clause jurisprudence by replacing the formalistic physical presence test with a flexible standard based on economic nexus. It empowered states to require remote sellers, particularly in e-commerce, to collect sales tax, reflecting modern economic realities.

Case Facts & Court Holding
Key Facts & Case Background
South Dakota, facing significant revenue losses from untaxed online sales, enacted a law requiring remote sellers to collect and remit state sales tax. The law was designed to directly challenge existing Supreme Court precedent. It applied only to sellers who, on an annual basis, delivered over $100,000 of goods or services or engaged in 200 or more separate transactions into the state, and it was not retroactive. Respondents, major online retailers including Wayfair, Inc., met these thresholds but had no physical presence (e.g., employees, property) in South Dakota. They did not collect the state’s sales tax, relying on the physical presence rule established in National Bellas Hess, Inc. v. Department of Revenue of Ill. (1967) and affirmed in Quill Corp. v. North Dakota (1992). South Dakota sued for a declaratory judgment, conceding the law was unconstitutional under Quill but asking the courts to reconsider that precedent. The South Dakota Supreme Court affirmed summary judgment for the retailers, holding it was bound by Quill. The U.S. Supreme Court granted certiorari to reexamine the validity of the physical presence rule.
Court Holding & Legal Precedent
Issue: Does the dormant Commerce Clause prohibit a state from requiring an out-of-state seller with no physical presence in the state to collect and remit sales tax on goods sold to consumers within the state?
No. The dormant Commerce Clause does not prohibit a state from requiring Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
