Frequently asked Questions about Marketplace Facilitator Laws

What exactly is a marketplace facilitator in South Dakota?

South Dakota law uses the term marketplace provider and defines this as: a marketplace provider is any person that facilitates a sale for a marketplace seller through a marketplace by:

  1. Offering for sale by the marketplace seller, by any means, tangible personal property, products transferred electronically, or services for delivery into this state; and
  2. Directly, or indirectly through any agreement or arrangement with third parties, collecting payment from a purchaser and transmitting the payment to the marketplace seller, regardless of whether the person receives compensation or other consideration in exchange for facilitating the sale or providing any other service

Online sales platforms like Amazon and eBay are considered marketplace facilitators under South Dakota law. 

Does this mean I can stop collecting South Dakota sales tax?

It depends. If you have nexus in the state (physical or economic) and you make sales to customers in South Dakota on platforms outside of the marketplace that are now automatically collecting and remitting, you will also need to collect tax on your end on the South Dakota orders that are processed on the other platforms. 

Does this mean I can cancel my South Dakota sales tax permit?

No, marketplace-only sellers should not cancel their sales tax permits. 

Do I still need to file a South Dakota sales tax return?

If you are registered to collect sales tax in South Dakota (i.e. you have an active South Dakota sales tax permit) then the state still requires that you file sales tax returns. Once you register for a license, you will be required to file a return based on the frequency the state has assigned you.

  • If you’ve previously registered, the state expects you to remain registered and continue to file returns (even if you are filing a $0 return).

What do I do with any South Dakota sales tax I have already collected?

If you have already collected South Dakota sales tax from buyers, it is vital that you remit that amount to the state. The only way to get in serious criminal trouble in sales tax is to collect sales tax from buyers on the state’s behalf but keep it in your own pocket.
