The South Carolina entry filing for LLCs formed elsewhere

To get in, an outside LLC files the Application for a Certificate of Authority by a Foreign Limited Liability Company (Form F0008) with the South Carolina Secretary of State and pays $110. The gate also asks for certificate of existence from the home-state Secretary of State, dated within 30 days.

Foreign LLCs send South Carolina nothing each lap.

What to carry

  • Certificate of existence from the home-state Secretary of State, dated within 30 days.
  • Registered home-state name and date of formation.
  • A registered agent based in the state (all of our picks offer this).
  • A budget for the $110 state fee.

The price of not registering

Registration has to come first if the LLC plans to sue in the state (S.C. Code 33-44-1008(a)). Its contracts are not voided (S.C. Code 33-44-1008(b)).

Reasoning for the order

For South Carolina, the criterion that decided the lead was steps the service takes over, at 27%.

Crossing into South Carolina means two states, and one provider for both beat SC Registered Agent.org.
