On March 6, 2017, the South Dakota Sixth Judicial Court ruled that the state’s economic nexus legislation is unconstitutional. The legislation – which became effective May 1, 2016 – requires remote sellers without a physical presence in the state to collect and remit South Dakota sales and use tax on sales in the state if the retailer makes in-state sales exceeding $100,000 or makes 200 or more separate sales transactions in the previous or current calendar year. In the ruling, the state acknowledged that under Quill Corp. v. North Dakota, the State of South Dakota is prohibited from imposing the sales tax collection and remittance obligations. The state agreed that the statute was unconstitutional and agreed with the summary judgement finding. This was expected as the case progresses towards an appeal to the U.S. Supreme Court in an effort to overturn Quill. For our previous news item, see South Dakota Enacts Economic Nexus Legislation.
