The walkthrough, stage by stage

  1. Stage 1

    When registration is a must

    South Carolina expects an out-of-state LLC to register before it transacts business in the state. What can go wrong without registering: claims brought by the LLC will not be heard in South Carolina until it registers (S.C. Code 33-44-1008(a)) existing deals still stand (S.C. Code 33-44-1008(b))

    Check it yourself: We pulled this from dor.sc.gov in October 2026

  2. Stage 2

    Order the home-state certificate

    South Carolina asks for certificate of existence from the home-state Secretary of State, no older than 30 days.

    Ask for it shortly before you file.

  3. Stage 3

    Line up the South Carolina registered agent

    Every LLC must name a registered agent with an in-state street address. The address has to be a street address in South Carolina for the agent, stated in the articles. P.O. boxes are not accepted.

    Our ranking covers this role.

    Check it yourself: We pulled this from scstatehouse.gov in October 2026

  4. Stage 4

    Now deal with the Application for a Certificate of Authority by a Foreign Limited Liability Company

    Complete the Application for a Certificate of Authority by a Foreign Limited Liability Company (Form F0008), include $110, and mail or upload both to the South Carolina Secretary of State.

    Check it yourself: We pulled this from dor.sc.gov in October 2026

  5. Stage 5

    Look ahead to the repeating filing

    South Carolina has no yearly report for foreign LLCs.
