How to form an LLC in Missouri

  1. Pick a name with “LLC” or “Limited Liability Company” in it, and check that it’s free on the Missouri Secretary of State business records.
  2. Name a registered agent: a Missouri resident, or a corporation authorized in Missouri, whose business office is the registered office.
  3. File the Articles of Organization (LLC-1) with the Missouri Secretary of State and pay $50.
  4. Get an EIN from the IRS. It is free and comes after the LLC is formed.
  5. Sign an operating agreement among the members. It sets ownership and voting rules and stays with your records.
  6. Stay in good standing. Missouri has no annual report for LLCs.

Mainstay Filing takes care of the agent, the filing, the EIN application for $199 a year plus Missouri’s fees.
