Sales tax reporting

How is sales tax collected?

When a business makes a sale of 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 that is charged 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.  To find sales tax rates, see the sales tax rates by address page from the South Dakota Department of Revenue.


When are South Dakota sales tax returns due?

The Department of Revenue will determine a filing frequency based on the expected volume of sales, which will be monthly, quarterly or annually. 

Filings are due the 20th day of the month following the reporting period, unless the 20th falls on a weekend or federal holiday, in which case would move to the next business day.

Even if the business had no sales during the reporting period, a filing is still required indicating no sales occurred.

Sales tax on purchases for resale

A business is able to purchase items to resell without paying state sales tax.  The tax liability is passed from the wholesaler or distributor to the retailer who will then charge sales tax to the end user of the item. 

Wholesalers and distributors will require a sales tax number and a completed South Dakota Certificate of Exemption form to document the items being purchased are for resale.
