South Dakota v. Wayfair: Physical Presence Is Not Required for Sales-Tax Nexus

Decision: South Dakota v. Wayfair, Inc., 585 U.S. 162 (2018).

A remote seller cannot rely on the absence of an office or employees in a state as a complete sales-tax collection defense. Wayfair rejected that categorical physical-presence rule. It did not create one national sales threshold or decide every challenge to South Dakota’s collection system. Wayfair, 585 U.S. at 188–89.

South Dakota’s economic-nexus law

The South Dakota law reviewed in 2018 covered sellers delivering more than $100,000 of goods or services into the state annually or completing 200 or more delivery transactions. These are the historical thresholds described in the opinion, not a current nationwide registration rule. The three large national retailers met the law’s threshold but did not collect South Dakota sales tax. Wayfair, 585 U.S. at 169–71.

Why Quill’s rule failed

The Court concluded that Quill and Bellas Hess had created an unsound and incorrect physical-presence rule. Modern commerce allows a business to have extensive economic and virtual contacts with a state without property or employees there, and the old rule distorted markets and disadvantaged local businesses.

Substantial nexus without physical presence

The Court found substantial nexus from these respondents’ economic and virtual contacts and significant South Dakota business. It then separately noted the law’s protection for limited activity, bar on retroactive collection and simplified administration system. Those safeguards informed the burden discussion; they were not a holding that every state using a sales threshold satisfies every Commerce Clause requirement. Wayfair, 585 U.S. at 187–89.

Remand preserved other questions

The Court vacated the state judgment and remanded for consideration of any remaining Commerce Clause issues. Wayfair eliminated the categorical physical-presence barrier; it did not approve every state collection regime regardless of burden, discrimination, or nexus.

Key takeaways

• Physical presence is not constitutionally required for sales-tax collection duties.
• Economic and virtual contacts can create substantial nexus.
• Thresholds, retroactivity, and administrative burden remain important.
• Multistate sellers must evaluate each jurisdiction’s current economic-nexus rules.
