When you need to register
If your LLC was formed in another state but "transacts business" in South Dakota — an office, employees, or regular in-state operations — South Dakota generally requires you to register before you do business here. You file Application for Certificate of Authority with the South Dakota Secretary of State, Business Services; see the official fee.
Your home state keeps charging its own fees too, so the true cost is both states added together.
