When should your business collect Sales Tax in South Dakota?

If your business has a sales tax nexus in South Dakota, you must collect and remit sales tax. A sales tax nexus is established if you have a physical presence in the state (e.g., a storefront, office, or warehouse) or meet certain economic thresholds (e.g., $100,000 in annual sales or 200 transactions in a year).

Once you establish a sales tax nexus in South Dakota, you should begin collecting sales tax on your taxable sales. Keep in mind that the sales tax rate varies depending on the location of your business and where the sale is made, as local jurisdictions may impose additional sales tax.

  • Attending trade shows, fairs, or conferences within South Dakota.

If your business meets any of the above criteria, you must collect and remit sales tax on your taxable sales in South Dakota.
