Formation in sequence

  1. Section 1

    Confirm the name is not taken

    The records at the Mississippi Secretary of State show every name in use. Look yours up before preparing any forms, because Mississippi can refuse a duplicate.

    It helps to have a fallback name ready.

  2. Section 2

    Arrange the registered agent

    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.

    Each recommended service can act as your registered agent.

  3. Section 3

    Choose how the paperwork is prepared

    The state fee, $50, applies either way; the recommended services charge $199 for their part.

  4. Section 4

    Section four is the Certificate of Formation

    The Certificate of Formation (Form F0100) goes to the Mississippi Secretary of State with a fee of $50; the governing law is Miss. Code Ann. § 79-29-201. Once accepted, the LLC exists.

    Reference: Reference: sos.ms.gov, consulted August 2026

  5. Section 5

    Apply for a federal tax identification number

    After formation, an EIN identifies the LLC to the IRS and lets it open accounts in its own name. The Mainstay Filing annual price already includes this section.

  6. Section 6

    Record how the company will be run

    A one-member Mississippi LLC should still have a written operating agreement in its records.

  7. Section 7

    Handle the recurring Mississippi filing

    Mississippi asks for the annual report every year, due April 15 and charges nothing for it.
