If you buy products exclusively to resale in the state of South Dakota, you can avoid paying sales tax on your purchases by presenting a South Dakota resale certificate at checkout. Always keep in mind that you should only use your resale certificate to buy items you intend to resell, rent or that you intend to use as a component part of an item for resale. Any other use of the resale certificate is usually considered unlawful.
