State laws on economic nexus vary and it’s hard to keep up if you’re doing business in multiple states. We’ve done the research for you and here’s all the information you need to know about economic nexus in South Dakota.

What is economic nexus in South Dakota?

With the recent South Dakota v. Wayfair Supreme Court ruling in favor of South Dakota, states are now free to pursue sales tax from eCommerce businesses who have a “significant presence” in their state.

Significant presence or “nexus” was preciously defined as having a physical presence (brick & mortar store or inventory in a fulfillment center like FBA). But with this recent ruling, this definition has been expanded to include economic activity in a state as well. This concept of triggering sales tax responsibility because of your economic activity in a state is now referred to as economic nexus.

Most importantly, what this means is that if you pass a state’s economic threshold for total revenue in that state and/or number of transactions in that state, you’re now legally required to register, collect and remit sales tax for that state.

What’s the threshold for economic nexus law in South Dakota?

• State: South Dakota
• Threshold: Sales of $100,000 in South Dakota in the state in the current or last calendar year. Note: As of July 1,  2023, South Dakota removed the 200 transaction requirement.
• Summary: According to the state, sellers that meet the sales thresholds are required to register for a South Dakota sales tax permit, collect sales tax on sales that ship into South Dakota, and remit sales tax to the state.
