The Missouri agent, in order
-
Step
1Learn what Missouri requires
Every LLC must name a registered agent with an in-state street address.
Where this comes from: Look it up at revisor.mo.gov; last checked October 2026
-
Step
2Check who qualifies as an agent
A Missouri resident, or a corporation authorized in Missouri, whose business office is the registered office. See RSMo 347.030.
-
Step
3Learn the address requirement
The address has to be a physical street address in Missouri. A P.O. box can be listed only together with a street address.
The agent's address, not your home, appears in the record when you hire a service.

Step
4Decide: serve yourself or hire someone
Our graded agents charge $99 to $149 a year; acting yourself is the other route if you qualify.
-
Step
5Get the agent on record
New companies list the agent on the Articles of Organization (Form LLC-1); changing agents later means filing with the Missouri Secretary of State again.
Where this comes from: Look it up at sos.mo.gov; last checked October 2026

6Watch the recurring filing
Since the state asks for no report, keeping the registered agent up to date is enough.
What you will pay
| Item | Paid to | Total |
|---|---|---|
| Registered agent service | The provider | $99 to $149 a year |
| Renewal | The provider | $99 to $149 a year |
