Do I file my Missouri operating agreement with the state?

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 20, 2026 · Last updated Aug 20, 2026

No. The operating agreement is an internal document you keep with your business records. Missouri files only the Articles of Organization to create the LLC. The Secretary of State never sees or files the operating agreement.
