A Grain of SALT: April State Focus – South Dakota

On April 17, the United States Supreme Court will hear oral argument in South Dakota’s case challenging the Court’s physical presence requirement for sales tax nexus. South Dakota v. Wayfair, Docket 17-494.

50 years ago, in National Bellas Hess v. Department of Revenue, 386 U.S. 753 (1967), the Supreme Court held that the Due Process and Commerce Clauses of the United States Constitution barred states from requiring remote retailers with no physical presence in a State to collect and remit sales tax. In 1992, the Court affirmed its prior ruling under the Commerce Clause. Quill v. North Dakota, 504 U.S. 298 (1992).

Quill has been at the center of state tax nexus controversy since the time of its issuance, as states have worked to restrict, and taxpayers have worked to expand the scope of the ruling. States and taxpayers have been continually tied up in disputes regarding the meaning of “physical presence” sufficient to trigger nexus. Concerned about the rapid growth of digital commerce, states have advanced increasingly aggressive theories of “physical presence” in an attempt to stem the loss of sales tax revenues from internet sales. Taxpayers, on the other hand, repeatedly have sought to apply the physical presence nexus standard to other types of taxes, principally income tax. Until South Dakota v. Wayfair, the Supreme Court declined to accept review of any case seeking further guidance with respect to the physical presence nexus standard. (more…)
