Top 30 Sales Tax Questions About South Dakota v. Wayfair

by TaxJar June 28, 2018

More than 2,000 merchants joined us to discuss the fallout from South Dakota v. Wayfair.

Here are the biggest takeaways:

  • We all have questions!
  • In fact, there are more questions than answers as we publish this post. A lot of specifics still need to be determined.
  • The first impact of the Supreme Court’s ruling will be felt on July 1 when some economic nexus laws go into effect that will impact ecommerce businesses.

Got questions? You’re not alone.

After reading through more than 1,600 comments from the webinar, we found a lot of the questions asked were very similar. So to try and help everyone understand what’s happening and how they’re impacted, we’ve compiled the top 30 most common questions below.

First we’ll answer the 20 most asked questions related to sales tax and this ruling, and then we’ll dive into the top 10 TaxJar-related questions.

Top 20 ruling-related questions from our webinar

What did the SCOTUS ruling change about sales tax?

  • Skip to this discussion in our webinar
  • Prior to this ruling, nexus was based on “physical presence.” By ruling in favor of South Dakota, The Supreme Court has decided physical presence is not required in order for a seller to be obligated to collect sales tax from buyers in a state. States can now declare that any seller with “economic nexus” is required to collect that state’s sales tax.  This means that if you meet a certain state’s definition of economic nexus (for example, exceeding a gross sales amount OR meeting a transaction threshold for volume of sales) then you are now legally required to collect and remit sales tax to that state. Each state’s economic nexus laws are different, and some states have not even passed economic nexus laws yet. You can read more about economic nexus here.

Do I need to collect in all 50 states right now?

  • Short answer, no. There’s only state sales tax in 45 of the states plus Washington D.C., so right off the bat, things are looking better than you thought, right?  
  • The important answer is that you ONLY need to collect where you have ‘nexus’ or a significant presence defined by that state (ie: in South Dakota they are defining significant as exceeding $100,000 in sales in South Dakota OR 200 transactions into South Dakota).
  • Once you meet a state’s definition for having nexus in that state, then you are legally required to register for a sales tax permit, collect, and remit sales tax to that state.
  • If you don’t have nexus in that state and don’t meet any of their thresholds for economic nexus or physical nexus, then you don’t need to collect or remit sales tax to that state. I encourage you to read more on understanding when to collect sales tax in our 101 guides.

What do I need to do to prepare?

Do states actually penalize sellers who are not sales tax compliant?

What states have economic nexus laws already on the books?

Just tell me, do I need to do anything today or can I wait?

Does having economic nexus one year automatically mean I have economic nexus the follow year?

  • It depends on the state and how they have defined significant presence, nexus, etc. For some states, you’ll need to renew your sales tax permit each year. In other states, your permit will automatically renew the following year unless you take action.
  • In addition, some of the new economic nexus laws are actually based on your previous years sales, not the current year. For example, in Alabama, the threshold is defined as $250,000/year based on the previous calendar year’s sales. So you actually wouldn’t have economic nexus here until you’ve met that requirement the following year (this doesn’t take into consideration physical nexus, etc. which may trigger you to have to comply there sooner).

Is every state going to pass an identical $100,000/200 transaction law like South Dakota passed?

  • Skip to this question within our recorded webinar
  • The Supreme Court did not rule that economic nexus needs to be set at $100,000/200 transactions, only that the South Dakota economic nexus law is legal. With that said, $100,000/200 transactions is the path of least resistance for any state looking to implement their own economic nexus law . Only time will tell how many states follow South Dakota’s lead and how many choose to set different economic nexus thresholds. As new laws are passed, we’ll update our economic nexus list.

I’m an international seller. Does this ruling impact me and do need to pay sales tax?

Does nexus apply to the specific channel or is it across all my channels? Do I have to collect sales tax on Shopify if I have nexus due to FBA?

  • Skip to that part of the discussion in the webinar
  • If one sales channel triggers nexus for you in a state, all your sales across all your channels is subject to sales tax in that state. Using the example above, nexus triggered by your Amazon FBA sales in a state would mean your Shopify sales in that state would also be subject to sales tax.

How does this affect Software as a Service (SaaS) and digital goods?

I’m a smaller seller. Compliance is starting to add up. How should I manage this so I don’t go out of business? Is there some kind of minimum revenue I need to make before I have to start worrying about sales tax?

  • Start by reading this article on when to register for a sales tax permit.
