Starting a Mississippi LLC, stage by stage

  1. Stage 1

    Confirm nobody else owns the name

    Do your name search at the Mississippi Secretary of State. Finding a clash now beats a rejected Mississippi filing later.

    See whether the web address is open while you are at it.

  2. Stage 2

    Get a registered agent in place

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

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

    Any of the services we phone can be your registered agent.

  3. Stage 3

    Pick your route

    Doing it yourself costs just the $50 state fee. A service adds $199 and takes over the forms; our ranking shows who we would phone.

  4. Stage 4

    Time to send in the Certificate of Formation

    What you need: the Certificate of Formation (Form F0100), a check or card for $50, and the Mississippi Secretary of State as the address. For the curious, see Miss. Code Ann. § 79-29-201.

    Check it yourself: sos.ms.gov, last viewed August 2026

  5. Stage 5

    Order a federal tax ID for the LLC

    State approval first, IRS number second. Mainstay Filing prepares the EIN application inside its package.

  6. Stage 6

    Document how the company runs

    The operating agreement is where the owners of a Mississippi LLC write down who owns what and how they decide things. You keep it with the company records; the state never sees it.

  7. Stage 7

    Deal with Mississippi's repeating filing

    Pencil the annual report into your calendar: no fee, every year, due April 15.
