What does the Supreme Court’s Wayfair decision mean?
Last week, the Supreme Court handed down its much anticipated decision in the case of South Dakota v. Wayfair. It might sound dull, but it will have a big impact in Minnesota. Online shopping will probably become more expensive. It could lead to a $150 million windfall for the state government.
So, what is it all about? Joseph Bishop-Henchman of the Tax Foundation provides a good explanation.
The case challenges South Dakota’s application of its sales tax to internet retailers who sell into South Dakota but have no property or employees in the state. At issue is the case Quill Corp. v. North Dakota from 1992, which set the property or employees standard for sales taxes using the Court’s (debated) dormant commerce clause power to restrict state taxation of interstate commerce.
Drumroll…South Dakota won. The Court laid out why South Dakota’s law is no burden to interstate commerce but made clear that more complex or overreaching laws would be. This was not too surprising, as during oral argument the justices expressed such frustration with the issue that it’s easy to see why they wouldn’t want this to be just the first of many cases. Better to articulate the rule well here. (We had filed a brief in the case, in support of neither party, urging the Court to uphold South Dakota’s law but draw a clear line preventing more problematic laws from being held as valid.)
As Justice Kennedy’s opinion states:
“That said, South Dakota’s tax system includes several features that appear designed to prevent discrimination against or undue burdens upon interstate commerce. First, the Act applies a safe harbor to those who transact only limited business in South Dakota. Second, the Act ensures that no obligation to remit the sales tax may be applied retroactively. S. B. 106, §5. Third, South Dakota is one of more than 20 States that have adopted the Streamlined Sales and Use Tax Agreement. This system standardizes taxes to reduce administrative and compliance costs: It requires a single, state-level tax administration, uniform definitions of products and services, simplified tax rate structures, and other uniform rules. It also provides sellers access to sales tax administration software paid for by the State. Sellers who choose to use such software are immune from audit liability. See App. 26–27. Any remaining claims regarding the application of the Commerce Clause in the absence of Quill and Bellas Hess may be addressed in the first instance on remand.”
The majority opinion, which twice cited the Tax Foundation’s brief, was authored by Justice Anthony Kennedy, joined by Justices Clarence Thomas, Samuel Alito, Ruth Bader Ginsburg, and Neil Gorsuch. Justice Thomas concurred to write that he should have joined the Quill dissent in 1992. Justice Gorsuch concurred, joining the majority in full and adding that he questions Commerce Clause doctrine. Four justices (Chief Justice John Roberts, Justice Stephen Breyer, Justice Sonia Sotomayor, and Justice Elena Kagan) dissented, agreeing that the Court got it wrong before but arguing that Congress should fix it.
