Naming a Mississippi registered agent, task by task

  1. Task 1

    The Mississippi rule in brief

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

    Source: Official page sos.ms.gov, last read October 2026

  2. Task 2

    Who can take the role

    Any individual, corporation or LLC with a physical address in Mississippi. Agents that serve for hire register with the Secretary of State as commercial agents. Legal source: Miss. Code Ann. § 79-29-113.

  3. Task 3

    The address rule

    The address has to be a physical Mississippi street address that is the agent's business office. P.O. boxes are not accepted.

    With a service, the public record shows its address instead of yours.

  4. Task 4

    Settle on the person or company

    Qualify and you can serve yourself. A professional from the list runs $99 to $149 per year.

  5. Task 5

    Report the agent's details

    A new LLC lists its agent on the Certificate of Formation (Form F0100), sent to the Mississippi Secretary of State. An LLC that swaps agents files an amendment with the same office.

  6. Task 6

    Check the record every year

    Mail from the state about the annual report reaches your registered agent. The filing is free every year, due April 15.
