What is Nexus?

You'll need to collect sales tax in South Dakota if you have nexus there. There are two main ways that sellers can be tied to a state when it comes to nexus: physical, or economic.

Physical nexus means having enough tangible presence, or activity in a state to merit paying sales tax in that state.

Affiliate Nexus

If your business is closely tied to another company in South Dakota, like a subsidiary or a parent company, this creates an affiliate nexus. It's about having strong business connections within the state.
