How registration works in Missouri
Move 1
Decide if the LLC must register in Missouri
If your out-of-state LLC does business in Missouri, register as a foreign LLC first. Skip registration and: A claim from an unregistered LLC will not go forward there (RSMo 347.163.1). Its contracts remain enforceable (RSMo 347.163.2).
Where this comes from: Source page dor.mo.gov , October 2026
Move 2
Request proof of good standing
Get certificate of good standing/existence from the home state, issued no earlier than 60 days.
Order it last so it is fresh when you file.
Move 3
Line up a Missouri registered agent
Every LLC must name a registered agent with an in-state street address. The address has to be a physical street address in Missouri. A P.O. box can be listed only together with a street address.
Each pick includes the registered agent.

Move 4
Finish and lodge the Application for Registration of a Foreign Limited Liability Company
That filing is the registration, and it costs $105.
