How a Mississippi LLC gets formed

  1. Task 1

    Name the company

    Open the business search run by the Mississippi Secretary of State before anything else; it shows whether the name already sits on the Mississippi register.

    If the first name fails, you want another ready.

  2. Task 2

    Line up a 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.

    This role comes with each recommended service.

  3. Task 3

    Do it yourself or hire a service

    Skip the services and you pay the state $50. Use one of our picks and you pay $199 extra to skip the forms.

  4. Task 4

    Work through the Certificate of Formation

    Here is the key filing: the Certificate of Formation (Form F0100) goes to the Mississippi Secretary of State with $50 (Miss. Code Ann. § 79-29-201), and that is what creates the company.

  5. Task 5

    Obtain an Employer Identification Number

    After Mississippi approves the LLC, ask the IRS for an Employer Identification Number; banks and payroll companies want it. This task is inside the Mainstay Filing package.

  6. Task 6

    Put the ownership rules on paper

    An operating agreement says who owns the Mississippi LLC and how decisions get made. It stays in your records and is not sent to the state.

  7. Task 7

    Handle Mississippi's recurring filing

    Put the annual report on your calendar: no fee, every year, deadline April 15.
