South Dakota v. Wayfair, Inc.

The decision that changed sales and use tax rules for remote (online and off-line) sellers, nationwide.

Taxing remote sales has changed

On June 21, 2018, the Supreme Court of the United States ruled in favor of the state in South Dakota v. Wayfair, Inc. The decision overruled a longstanding physical presence rule, allowing states to require remote sellers to collect and remit sales tax.

Since Wayfair, most (but not all) states have adopted new rules defining what establishes a sales and use tax obligation, known as nexus. Unfortunately for businesses, no two state sales tax nexus laws are alike.
