On June 14, 2022, the Senate Finance Committee heard testimony on the impact on small businesses and remote sales of the U.S. Supreme Court’s decision in South Dakota v. Wayfair, Inc., 138 S. Ct. 2080, 201 L. Ed. 2d 403 (2018).
In Wayfair, the U.S. Supreme Court ruled that a business’s physical presence in a state (or lack thereof) wasn’t determinative for purposes of whether a state could require the business to collect sales and use taxes from customers located in the state. Overturning decades of precedent, the decision effectively gave states the green(ish) light to force remote sellers to collect sales and use taxes.
Witnesses before the committee discussed a number of difficulties that remote sellers were having in complying with tax collection requirements across multiple states. These include dealing with varying dollar and transaction thresholds, different items subject to sales and use tax, the complexity of local taxes, and costs associated generally with staying compliant across multiple jurisdictions.
There were also calls for Congress to take action to regulate the states’ power to impose tax collection requirements on remote sellers (although how realistic this remains uncertain).

 Wayfair, 138 S. Ct. at 2099. The Wayfair decision turned on the Court’s interpretation of the Commerce Clause of the U.S. Constitution. The Commerce Clause gives Congress the power “to regulate commerce with foreign nations, and among the several states, and with the Indian tribes.” U.S. Const. art. I, § 8, cl. 3. The Court noted that, “[a]lthough the Commerce Clause is written as an affirmative grant of authority to Congress, . . . in some instances it imposes limitations on the States absent congressional action.” Wayfair, 138 S. Ct. at 2089. Going forward, the question of whether a taxpayer has substantial nexus with a taxing state is to be determined based on whether the taxpayer “‘avails itself of the substantial privilege of carrying on business’ in that jurisdiction.” Wayfair, 138 S. Ct. at 2099 (quoting Polar Tankers, Inc. v. City of Valdez, 557 U. S. 1, 11, 129 S. Ct. 2277, 174 L. Ed. 2d 1 (2009)).
 Cases holding that physical presence was a must in this context include National Bellas Hess, Inc. v. Department of Revenue of Illinois, 386 U.S. 753, 87 S. Ct. 1389, 18 L. Ed. 2d 505 (1967) and Quill Corp. v. North Dakota, 504 U. S. 298, 112 S. Ct. 1904, 119 L. Ed. 2d 91 (1992). The Court decided to reverse course in light of the far-reaching technological and social changes caused by the Internet in the years since the Quill decision came down. However, there’s still a live question of whether certain aspects of a state’s tax system may impose an undue burden on interstate commerce that would render its application to remote sellers unconstitutional. Wayfair, 138 S. Ct. at 2099-100.
