South Dakota Business Tax Nexus
What is Tax Nexus in South Dakota?
Nexus is the legal connection between a business and South Dakota that requires the business to collect and remit sales tax. South Dakota enforces both physical and economic nexus standards for sales and use tax purposes. Since there is no income tax, nexus for income tax purposes does not apply.
Physical Nexus
- Maintaining an office, store, warehouse, or place of business in South Dakota
- Having employees, agents, or independent contractors operating in the state
- Storing inventory in South Dakota, including FBA fulfillment centers
- Operating vehicles or equipment within state borders
- Owning or leasing real or tangible personal property in South Dakota
Economic Nexus (Remote Sellers)
| Threshold Type | Detail |
|---|
| Sales Threshold | $100,000 in South Dakota sales in the current or prior calendar year |
| Transaction Count Threshold | 200 or more separate transactions into South Dakota |
| Effective Date | March 1, 2019 (post South Dakota v. Wayfair, 2018) |
Click-Through & Affiliate Nexus
South Dakota enforces click-through and affiliate nexus. If an out-of-state seller enters into agreements with South Dakota residents who refer customers through links or other means, and cumulative sales exceed $10,000 annually from those referrals, sales tax nexus is established.
South Dakota State Income Tax
Corporate Income Tax
South Dakota does not impose a corporate income tax. C corporations, S corporations, LLCs, and all other business entities are not subject to state-level income or franchise tax on business profits. This is a key advantage for businesses choosing to incorporate or operate in South Dakota.
Individual Income Tax
South Dakota does not levy a personal income tax on individuals. Residents pay no state tax on wages, salaries, investment income, retirement distributions, or any other form of personal income. This makes South Dakota one of only nine states with no individual income tax.
