Collecting sales tax in South Dakota

Now, let’s look at the steps to collect sales tax in South Dakota.

How to collect sales tax in South Dakota if you are not based in South Dakota (Out-of-State)

South Dakota’s economic nexus laws require out-of-state sellers to collect and remit sales tax once they meet the $100,000 sales or 200 transactions threshold from South Dakota customers in the current or prior calendar year.

To register for a South Dakota seller's permit, you must file on the Department of Revenue website if you do not have an in-state physical presence. Complete the online or paper application to receive your sales tax license.

Once registered, begin charging South Dakota state sales tax (4.5%) plus any applicable municipal taxes on all taxable sales shipped to South Dakota addresses. You must file regular sales and use tax returns even for periods without sales.

Carefully document all out-of-state sales and maintain thorough sales records. Detailed invoices, shipping reports, and exemption certificates ensure you can validate any sale claimed as exempt or shipped out of state during a South Dakota sales tax audit.

Consider sales tax automation software to accurately calculate rates, file returns, and integrate seamlessly with your accounting, e-commerce, POS, or billing systems. This eliminates compliance headaches so you can focus on growing your South Dakota customer base.

Should you collect sales tax on shipping charges in South Dakota?

If the products sold are taxable, then delivery and shipping charges by South Dakota sellers are generally considered part of the sales price and subject to state and local sales taxes.

However, if all products on the order qualify as exempt, then shipping charges tied directly to that order are also exempt. Ensure your invoices list shipping as a separate line item to avoid confusion. Maintain thorough recordkeeping on taxable vs. exempt sales and corresponding shipping charges.

Filing and paying sales taxes in South Dakota

All retailers registered for a South Dakota sales tax permit must file regular sales and use tax returns with the Department of Revenue, even for periods without taxable sales. You can submit returns and payments online, by phone, or by mail.
