Wayfair Ruling Redefines State Tax Filing Requirements for Businesses

As e-commerce continues to grow and evolve so do the states methods for the assessment and collection of sales and use tax. We wanted to take the opportunity to alert you of a recent Supreme Court ruling which will likely have a significant impact on numerous businesses’ sales tax compliance requirements moving forward. On June 21st, 2018 in South Dakota v. Wayfair, Inc. the Supreme Court standardized taxing rules for traditional retailers and online transactions, ruling that states and localities may collect sales tax on all purchases over the internet. This decision overrules the previous case law set in Quill Corp. v. North Dakota which ruled in favor of a physical presence requirement test for purposes of the assessment and collection of sales and use tax.

Specifically, in 1992 the Supreme Court ruled in Quill Corp. v. North Dakota that it was unconstitutional for states to demand that out-of-state sellers collect and remit sales taxes on all purchases. The court said that states could not extend their taxing authority to companies that had no stores, warehouses or “physical presence” within the state. As online shopping has grown exponentially since 1992, the state of South Dakota and 41 other states urged the high court to revisit the question and consider overturning Quill Corp v. North Dakota. In 2016, while states continued to push for the reversal of the Quill decision, South Dakota became the first state to enact a pure economic nexus statute for sales and use tax collection purposes. More specifically, South Dakota required all entities with annual South Dakota sales of at least $100,000 or 200 separate transactions in the state to collect and remit South Dakota sales and use tax. As a result of noncompliance, South Dakota v. Wayfair, Inc. became a significant Supreme Court case to determine the legality of a state’s right to collect sales and use tax from online retailers selling to customers located in their state. The Supreme Court concluded that the long-standing physical presence rule put businesses with a physical presence in the state at a competitive disadvantage compared to remote sellers because entities with a physical presence were required to collect and remit sales and use tax while remote sellers were not held to the same requirement.

The South Dakota v. Wayfair, Inc. case fundamentally redefines a taxpayers potential filing requirements in all states. Not only are additional sales and use tax filing requirements expected to be enforced, states may also begin to require income tax returns from taxpayers with economic nexus. It can be expected for other states to act quickly to enact their own economic nexus standards and thresholds to capture sellers without a physical presence in the state.  Specifically, the following states already have laws in place to allow them to begin enforcing economic nexus rules in the very near future; Alabama, Connecticut, Georgia, Hawaii, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Minnesota, Mississippi, North Dakota, Oklahoma, Pennsylvania, Rhode Island, South Dakota, Tennessee, Vermont, and Washington. Although many states do not currently have laws in place to enforce an economic nexus regime, it likely will not be long before they mirror the aforementioned economic nexus enforced states.

As we move forward with our internal analysis of this ruling along with monitoring various specific state developments, we feel it is important to be proactive in determining the states where economic nexus may exist.
