August 2025
A remote seller must obtain a sales tax

• the business has a physical presence in South Dakota.
• the business does not have a physical presence but has more than $100,000 in gross sales into South Dakota in the previous or current calendar year.

Businesses without a physical presence in South Dakota are considered to be remote sellers.
Remote sellers are required to register by the first day of the month that starts at least thirty days after the threshold is met.
Example: license from the South Dakota
Department of Revenue.
Apply for a sales tax license online at www.sd.gov/taxapp or through the
Streamlined system at www.streamlinedsalestax.org.
An out-of-state seller's gross revenue for sales into South Dakota exceeds $100,000 on May 28. The seller would not be required to register and begin collecting South Dakota sales tax until July 1.
Gross sales or transactions include selling, renting, or leasing products or services (including products delivered electronically) into South Dakota (SDCL ch. 10-64). The Department understands it is important to partner with the business community to ensure a successful transition.
We understand there are preparatory steps remote sellers need to take before collections begin. If there are concerns about complying with this timeframe, please contact the Department of Revenue directly for further assistance.

How does a remote seller file and pay taxes with South Dakota?

• Once licensed, a remote seller can file, pay, and amend tax returns by using South Dakota's online tax filing system EPath. Will South Dakota go back and try to recover taxes that weren't collected and paid on purchases made prior to the ruling?
• No, the state cannot go back and retroactively collect sales tax from a remote seller. The state is legally precluded from enforcing retroactive tax collection on remote sellers for any sale made prior to November 1, 2018 (SDCL 10-64-6). Once a business reaches the threshold of gross sales of more than $100,000 into South Dakota, will the state tax all of that company's in-state transactions from the previous year?

If a business meets the $100,000 gross sales threshold in the previous calendar year, the business is required to

• become licensed and remit South Dakota sales tax for the following year.

If a business meets the $100,000 gross sales threshold during the current calendar year, the business is required

Does South Dakota require a remote seller to file separate returns for state and municipal sales taxes?
