What Happened in South Dakota v. Wayfair, Inc.

On June 21, 2018, the United States Supreme Court ruled in a 5-4 decision in South Dakota v. Wayfair, Inc., et al, that states can generally require an out-of-state seller to collect and remit sales tax on sales to in-state consumers even if the seller has no physical presence in the consumer’s state.  In doing so, the Court overruled 50 years of its own precedent.  The decision allows states to define a sales threshold (either by dollar amount or the number of transactions) which will trigger this collection requirement.  

Why Did Wayfair Happen?

Before Wayfair, businesses with no employees or property in a state (i.e., no physical presence) were not considered to have sales tax “nexus” and therefore had no requirement to collect and remit tax on these sales.  Instead, the consumer was responsible for reporting and self-remitting a use tax to the state at the same rate on those purchases – a scenario which unsurprisingly led to fewer tax dollars being collected by the state.  As a result, many state governments asserted that they were being unfairly hindered in their ability to collect taxes on these sales.  Likewise, many in-state taxpayers complained that they were being undercut by out-of-state remote sellers that were not required to collect the same sales taxes they were.

In a move to bring the issue to a head, South Dakota enacted a law in 2016 which required sellers to sell more than $100,000 of goods or services into the state or engage in 200 or more separate transactions for the delivery of goods or services into the state on an annual basis, to collect and remit sales tax on all taxable sales into the state.  Online retailer Wayfair challenged this law as being contrary to established Supreme Court precedent and unconstitutional.  In ruling in favor of South Dakota, the Court held that its prior rulings on the matter, some of which dated back to the mid-1960’s and required the seller to have in-state physical presence before it could be required to collect sales tax, were outdated and effectively caused market distortions with modern technology giving an advantage to e-commerce and out of state retailers over dealers with in-state locations.

What Does the Wayfair Sales Tax Case Mean?

As a result of this landmark decision, states now generally have the right to require out-of-state companies to collect and remit sales tax based on an objective measure of sales and/or transactions (“economic nexus”). Companies that previously relied on the physical presence test to avoid collecting other state’s sales taxes will now need to analyze their sales data to ensure they comply with individual state sales tax laws.

The District of Columbia and the 45 states that impose a sales tax followed the Wayfair case closely and unsurprisingly reacted swiftly and favorably to their newfound authority to tax previously untaxable transactions. As of early 2021, only 3 “holdout” states (Florida, Kansas and Missouri) had yet to enact an economic threshold similar to South Dakota’s although Kansas asserted the authority to tax any taxable sale into the state regardless of the dollar amount. However, Kansas and Florida enacted $100,000 thresholds based on Wayfair during their spring 2021 legislative sessions.  Finally on May 14, 2021, Missouri became the last jurisdiction to enact a Wayfair-type economic nexus threshold.

Clearly, the Wayfair decision has added complexity to compliance with state sales tax laws. In addition to the enactment of the new nexus thresholds that taxpayers must be aware of, some states have subsequently modified their provisions to change the initial dollar threshold (e.g., Tennessee decreased from $500,000 to $100,000) or eliminate the 200 transaction prong altogether (e.g., Kentucky, Louisiana, South Dakota, and Wyoming). Companies will need to proactively monitor and react to state law changes to thresholds, rates, and sourcing guidance.

Compliance and Planning Considerations

  1. Will this affect any non-sales taxes?
    • Will the states apply these type provisions to taxes other than sales taxes?
    • If so, will you be required to file for gross receipts or franchise taxes in addition to sales tax?
  2. Thresholds are determined on an annual basis. However, states have defined the starting point of this basis at different periods (i.e. Prior calendar year, state fiscal year, current calendar year, etc.).
  3. How will the states measure the dollar thresholds?
    • Do the states look to taxable sales only, or do they include all sales?
    • If the latter and your companies mostly sell to resellers, will your company be required to file 0 returns monthly?
  4. How will this affect account payables if vendors are to charge sales tax?
    • If they are not charging sales tax, are there circumstances where my company will need to include purchases for use tax?
  5. Does my company have a process to track and maintain exemption certificates?
  6. How does each state source sales?
  7. Does the state include sales delivered electronically or only for the tangible property?
  8. Does the state require the aggregation of affiliated businesses?
  9. Does my company have the capacity to comply with these changes?
    • Will we need to hire additional resources?
    • Will we need to engage with outside consultants?
    • Will we need to purchase or upgrade ERP systems?

Which States have Economic Nexus?

When reviewing the new sales tax economic nexus chart to determine the impact on your company, comparing your company’s sales-by-state to the threshold on the chart is just the beginning. The key is to comply without creating unintended consequences. Your company must take the proper steps to address the domino effect of issues created by the new sale tax nexus landscape before your company registers and starts collecting sales tax in new states.  (The thresholds are those currently in effect. These thresholds can and do change. Therefore, taxpayers should always check to make sure these thresholds are still current.)

What Actions Should I Take?

Companies should review their sales data to determine potential filing requirements. As part of that analysis, companies should review the taxability laws of states they haven’t had to address before and determine if any exemptions or exclusions apply. Items or services that are taxable in one state may not be in another.

Once this review is complete, companies should pause to determine whether they should register and start collecting or if there is an opportunity, based on the facts and a state’s law, to not register and collect. The Commerce Clause still applies, and Congress could act to regulate interstate commerce and impose limitations. Consequently, there is a need to act, but in a cautious and controlled manner. Voluntary disclosure agreements and amnesty programs may also come into play for companies who haven’t collected in prior years when they should have, even before this ruling.

Companies that haven’t had to file sales tax returns in many states and thus have filed manually, may now need an automated solution to comply with thousands of taxing jurisdictions. Companies should consider different providers to find the best fit for their industry and transaction volume.

Companies should follow state legislative actions and non-legislative actions closely. Don’t play the ‘wait and see’ game; prepare now regardless of how things shake-out over the next few months. Congress could act or new litigation and challenges could arise.

A 12-Step Program on How to Respond to Wayfair

Make your company audit-ready, and mitigate sales and use tax risk by completing the following steps:

  1. Determine Prospective Nexus. Compare the chart to your company’s sales-by-state for the last calendar year or prior 12-months (depending on the state). If your company is over the threshold in any state, move on to Step 2.
  2. Determine Prior-Year Nexus. Review your company’s connections or physical presence activity in prior years for the states you identified in Step 1.
  3. Evaluate State Income Tax Impact. Conduct both #1 and #2 for state income tax purposes to avoid collateral damage.
  4. Determine Taxability. The tax treatment (taxability) of what your company is selling (i.e., products, services, bundled transactions, etc.) may be different in each new state.
  5. Identify Exemptions. Determine if any exemptions apply to the products or services your company is selling in each new state.
  6. Get Your Use Tax Right. Perform a reverse audit of your company’s purchases (accounts payable) to determine overpayments/underpayments in preparation for more vendors charging your company sales tax.
  7. Obtain Exemption Certificates. Prepare to offer exemption certificates to vendors that start charging your company sales tax on your purchases.
  8. Mitigate Liability. Consider whether your company should enter into Voluntary Disclosure Agreements with any new states before collecting sales tax prospectively.
  9. Consider Tax Decision Software. Determine whether your company needs to acquire and implement new tax decision software or will continue to use a manual process.
  10. Assess Outsourcing Compliance. Determine whether outsourcing your sales tax compliance would be cost-beneficial.
  11. Register and File. Register in each new state for sales tax collection while considering the income tax impact and other taxes. File timely returns on a go-forward basis.
  12. Monitor and Maintain. Monitor state tax law changes and business changes. Maintain taxability engine rules or a manual taxability matrix for sales and purchases on an annually.
