- Does South Dakota have a Click-Through Nexus?
To best understand your tax obligations, new businesses need to consider how they are doing business and the type of relationships they have with buyers and any third parties to their transactions.
Let’s discuss some questions that will help you understand the nature of your small business and the subsequent tax implications.
Is South Dakota an origin or destination-based sales tax state?
South Dakota is a Destination-based sales tax state. This simply means you’ll want to have your Point-of-Sales system configured to track sales tax based on your buyer’s location vs your business location.
Protip: Charge sales tax based on your buyer’s location rather than your location
What creates a tax nexus with the state of South Dakota?
Having nexus, also known as "sufficient business presence,” with South Dakota means your business has established a taxing connection with a state. When this happens, you are required to collect and remit sales tax in South Dakota because you created a sales tax Nexus.
Even if your business maintains its main headquarters in another state, you may still have to charge and pay sales tax to the South Dakota Department of Revenue even if you never step foot in South Dakota.
So, how do you create sales tax nexus in South Dakota?
A business establishes a nexus in South Dakota by:
- having a business location in South Dakota;
- having property stored in South Dakota;
- employing any person in South Dakota;
- contracting with a salesperson or other agent in South Dakota;
- leasing equipment used in South Dakota;
- performing services in South Dakota;
- licensing the use of intangible property in South Dakota, or transporting property in South Dakota using the taxpayer’s vehicles.
Let’s talk a bit more specifically about where your goods are stored, such as in the instance of an Amazon warehouse.
Does Amazon have fulfillment centers in South Dakota?
No, not at this time.
This is relevant for our customers that sell on Amazon or through Amazon’s FBA program.
In such cases we can help guide a small business through this regulatory maze! We use tools like A2X and Wherestock to identify where our clients' inventory is currently being held and shipped from so that we can keep them in compliance.
Does South Dakota have economic nexus?
Does it ever! Yes, South Dakota has the OG economic nexus law (Wayfair vs. South Dakota the landmark precedent-setting case). As of November 1st, 2018, remote sellers are liable to pay sales tax beyond a certain threshold. This means that even businesses without a physical presence or traditional nexus can be required to register for, collect, and pay sales taxes.
The threshold for registering is having a cumulative gross revenue of over $100,000 or more than 200 transactions in a year to South Dakota purchasers.
For more information see the South Dakota DOR’s remote sellers page here.
Does South Dakota have click-through nexus?
Yes, it does, with the same thresholds as above: $100k in a year or 200 transactions in a year. This impacts affiliate marketers or those who gain income by referring rather than transacting sales.
Is South Dakota a streamlined sales tax state?
Yep! Since October, 2005 South Dakota has been a full member of Streamlined Sales Tax.
If you are planning on taking advantage of the Streamlined Sales Tax as a business, it is recommended that you use a Certified Service Provider though businesses may opt to register themselves without a CSP. Ultimately the aim of streamlined sales tax is to simplify payment to multiple different states of sales and use tax. It isn’t required that you utilize them, but it can significantly reduce complexity to do so, especially if your business sells in multiple states.

Other common examples of an exempt buyer may include:
- Government agencies

- Out-of-state buyers (should their business not have nexus in their home state).
Note that a non-profit status doesn’t instantly confer tax exemption.
What should I do if my customer is exempt from sales tax in South Dakota?
Purchasers who are tax exempt must have completed resale certificate (PDF) and must present their completed exemption certificate at the time of purchase. It is then incumbent upon the seller to hold on to this exemption certificate. Failure to do so may leave you unable to justify tax exempt sales.
Remember, you always want to collect and file a copy of the exempt certificate. Such certificates must be produced upon request in the event of an audit to justify tax-exempt sales.
What happens if I lose a South Dakota sales tax exemption certificate?
Obviously this issue is best to be avoided! Imagine finding out you’ll be audited and discovering you cannot produce an exemption certificate for a buyer... That nightmare scenario would mean you could be held liable to pay all taxes on behalf of the buyer. This is a bad scene and can be avoided by taking proper care of your paperwork... Which happens to be one of our specialties! :)
