Why do you need to collect sales tax in South Dakota?

If you’re selling goods and services in South Dakota then sales tax might apply! To determine your obligation, you need to understand “nexus,” which ties businesses to states for tax purposes.

Two types of nexus exist:

  1. Physical Nexus: Having a physical presence, like an office, warehouse, or employees in South Dakota, triggers this type. If you do, you likely need to collect sales tax.
  2. Economic Nexus: This kicks in when your sales within South Dakota exceed a certain economic threshold. Even without a physical presence, surpassing this threshold requires collecting sales tax.
