How a Missouri LLC is formed

  1. Procedure 1: Select a name

    The first observation to make is a name search at the Missouri Secretary of State, before any filing is prepared under a name already in use.

    TipA spare name saves a second round.

  2. Procedure 2: Appoint a registered agent

    Every LLC must name a registered agent with an in-state street address. A Missouri resident, or a corporation authorized in Missouri, whose business office is the registered office.

    The address has to be a physical street address in Missouri. A P.O. box can be listed only together with a street address.

    TipThe registered agent role is part of each ranked service.

    Specimen: revisor.mo.gov (observed October 2026)

  3. Procedure 3: Compare filing alone with engaging a service

    Without a service the whole bill is the state's $50. Each of the ranked services adds $199 and handles the paperwork.

  4. Procedure 4: Prepare the Articles of Organization

    Deliver the Articles of Organization (Form LLC-1) and $50 to the Missouri Secretary of State. That filing forms the LLC.

    Specimen: sos.mo.gov (observed October 2026)

  5. Procedure 5: Apply to the IRS for an EIN

    The IRS issues EINs, not Missouri. Apply after approval and pass the number to the bank. Mainstay Filing performs the EIN application as part of its package.

  6. Procedure 6: Draft the operating agreement

    The operating agreement records who owns the Missouri LLC and how decisions are made. It stays in the company records and is never sent to the state.

  7. Procedure 7: Maintain good standing in Missouri

    With no report required, the registered agent is the only standing obligation.
