What does NOT require registration in South Dakota 10 activities

South Dakota carves 10 activities out by statute. On their own, none of them requires a foreign LLC to register.

  • Maintaining, defending, or settling a lawsuit or proceeding
  • Holding meetings and carrying on internal company affairs
  • Maintaining accounts at financial institutions
  • Maintaining a transfer, exchange, or registration office for the company's own securities
  • Selling through independent contractors
  • Soliciting or taking orders that must be accepted outside the state
  • Creating or acquiring debts, mortgages, or security interests in real or personal property
  • Collecting debts, enforcing security interests, and holding property acquired that way
  • A single isolated transaction completed within 30 days and not part of similar transactions
  • Transacting business in interstate commerce

Under SDCL 47-34A-1003. South Dakota has NO property-ownership safe harbor, and subsection (b) reverses it: owning income-producing real or tangible personal property in South Dakota DOES constitute transacting business.

Whether your name reaches the public record depends on how you set the LLC up: South Dakota asks for manager names on the articles only if you elect manager-managed. What the annual report collects is not settled and we would rather say so than guess.
