South Dakota Business Considerations · Small Business Addendum

South Dakota has no personal income tax and no corporate income tax, but it is notable as the state whose Supreme Court decision in South Dakota v. Wayfair established economic nexus for sales tax nationwide. If you sell to South Dakota customers above certain thresholds, you may have a sales tax obligation even without a physical presence there. This addendum covers the no-income-tax advantage, sales and use tax including economic nexus, annual report filing, business license requirements, registered agent obligations, and unemployment insurance. Written in plain English.
