The U.S. Supreme Court today handed down its anticipated decision in South Dakota v. WayfairSouth Dakota v. Wayfair was a 2018 U.S. Supreme Court decision eliminating the requirement that a seller have physical presence in the taxing state to be able to collect and remit sales taxes to that state. It expanded states’ abilities to collect sales taxes from e-commerce and other remote transactions. . The case challenges South Dakota’s application of its sales taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. 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 taxA sales tax is levied on retail sales of goods and services and, ideally, should apply to all final consumption with few exemptions. Many governments exempt goods like groceries; base broadening, such as including groceries, could keep rates lower. A sales tax should exempt business-to-business transactions which, when taxed, cause tax pyramiding. es 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 auditA tax audit is when the Internal Revenue Service (IRS) conducts a formal investigation of financial information to verify an individual or corporation has accurately reported and paid their taxes. Selection can be at random, or due to unusual deductions or income reported on a tax return. 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.

All eyes will now turn to Congress and the states. Congress has been stymied between alternate versions of federal solutions: the Remote Transactions Parity Act (RTPA) or Marketplace Fairness Act (MFA), which lets states collect if they agree to simplify their sales taxes, and a proposal from retiring Rep. Bob Goodlatte (R-VA) that would make the sales tax a business obligation rather than a consumer obligation, and have it collected based on the tax rate where the company is located but send the revenue to the jurisdiction where the customer is located. RTPA and MFA are more workable and more likely to pass, but Goodlatte controls what makes it to the House floor, so nothing has happened. Maybe today’s decision will change that.
In the states, a reminder, 31 states currently have laws taxing internet sales. Today’s decision will certainly change how states look at these laws but we may see states trying to see if their versions could survive even if they are less simplified and direct than South Dakota’s law. This ruling is not a blank check for states. The Court specifically observed that South Dakota’s law, and its tax laws generally, minimizes the burden on interstate commerce. Other states should craft their laws accordingly.
