Bringing a foreign LLC into South Dakota
The fee to register is $750, paid when the Application for Certificate of Authority, Foreign Limited Liability Company is filed with the South Dakota Secretary of State. Alongside it, the state asks for certificate of Existence.
After that comes the annual report ($55), 1st of the anniversary month.
Documents to collect
- Certificate of Existence.
- Home state record: legal name and formation date.
- A registered agent with a street address here; each provider ranked above can supply one.
- Budget for the $750 filing fee.
Consequences of staying unregistered
What the LLC signed is still enforceable (SDCL 47-34A-1008(b)).
Why Mainstay Filing leads
Requirements handled settled first place in South Dakota; it carries 24% of the score, and the other criteria are service cost across three years, renewal behavior, state-specific fit, pass-through of state fees.
A foreign LLC lives in two states, and coverage settled the order.
