Wayfair has, for now, answered the question (at least, in part) of whether economic activity creates substantial nexus under the Commerce Clause for purposes of sales and use taxes. However, questions remain regarding whether and to what extent business activity tax nexus standards could be impacted. While states had boldly asserted economic nexus in the business activity tax context pre-Wayfair, the response since has been somewhat muted, until recently. Three states, Pennsylvania, Texas, and Wisconsin, have recently sought to fill in the blanks with regard to business activity tax nexus, with varied and inconsistent results that may raise more questions and concerns than answers.
State efforts to undermine or challenge the Quill Corp. v. North Dakota, 504 U.S. 298 (1992) physical presence standard escalated this summer with the enactment of two sales and use tax laws targeting marketplace operators. Minnesota House File 1 (“H.F. 1”) and Washington House Bill 2163 (“H.B. 2163”), signed into law on May 30, 2017 and July 7, 2017, respectively, impose sales and use tax obligations on certain marketplaces that facilitate the sales of out-of-state third party retailers. Minnesota and Washington are the first two states to enact such laws, and similar legislation is currently pending in the Pennsylvania General Assembly.
