2Choose your 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.
Every class favorite here can be your registered agent.

7Keep the LLC active
Missouri skips the yearly report. Keep the registered agent up to date and you pass.

|---|---|---|

How we graded the Missouri picks

Without a report to bundle, the lead over MO Registered Agent.org is thin.
