Wholesalers and distributors will require a sales tax number and a completed South Dakota Certificate of Exemption form (also referred to as a resale certificate or sales tax exemption certificate) to document the items being purchased are for resale.

Sales tax reporting

How is sales tax collected?

When a business sells a taxable product or service, the business charges the appropriate sales tax rate to the customer. This tax is collected by the business who then sends it to the South Dakota Department of Revenue.

How much sales tax is charged?

The sales tax rate is based on the gross receipts of all retail sales and varies depending on the address of the business if the purchase is made in the store. When shipping in-state, the sales tax is based on the address of the purchaser.

In addition to the statewide tax, there are additional sales taxes that may be added by cities and municipalities. The municipal gross receipts tax (MGRT) is most commonly seen on the sale of alcoholic beverages, eating establishments, lodging accommodations, etc. To find sales tax rates, see the sales tax rates by address page from the South Dakota Department of Revenue.
