The stages

  1. Stage 1

    The South Carolina rule in plain terms

    Every LLC must name a registered agent with an in-state street address.

    Check it yourself: scstatehouse.gov, seen in October 2026

  2. Stage 2

    Who counts as an agent

    A South Carolina resident, a South Carolina corporation, another LLC, or a corporation or company from another state authorized to do business in South Carolina. Legal basis: S.C. Code § 33-44-108.

  3. Stage 3

    Use an office address that qualifies

    The address has to be a street address in South Carolina for the agent, stated in the articles. P.O. boxes are not accepted.

    A service keeps your home address off public records.

  4. Stage 4

    Go solo or hire out

    A qualified owner can act as agent. Prefer to hand it off? Our recommended agents bill $99 to $149 yearly.

  5. Stage 5

    Report the agent's details

    The Articles of Organization asks for the agent's name and address, and the South Carolina Secretary of State also handles the change filing when you switch.

    Check it yourself: scstatehouse.gov, seen in October 2026

  6. Stage 6

    Update when something changes

    No report is due, so your single job is to keep the registered agent appointment up to date.
