Registered Agents in Missouri: What the Law Requires

Missouri requires every LLC, corporation, and registered business entity to maintain a registered agent. The agent holds a physical address in the state and is available during business hours to accept legal documents and official correspondence on your behalf. Here is what you need to know about the role, the requirements, and your options.

The Registered Agent's Job

Your registered agent is the designated point of contact between your business and the legal system. When any of the following need to reach your entity, they go through your agent:

• Courts serving you with lawsuit papers
• The Missouri Secretary of State sending compliance notices
• State tax authorities delivering assessments or correspondence
• Government agencies issuing regulatory communications

The agent accepts these documents and ensures they reach you. In our case, we scan and forward them the same day via email and your online portal.

Missouri's Unique Rules

Missouri has a few quirks in its registered agent law worth knowing:

Only individuals and corporations. Under RSMo 351.370, Missouri only explicitly authorizes individuals and corporations to serve as registered agents. LLCs are not specifically mentioned as eligible to serve in this role. This is unusual compared to most states.

No self-appointment. Your business entity cannot designate itself as its own registered agent. You need a separate person or corporation.

PO box rule. Missouri allows a PO box as part of the registered agent address, but only in conjunction with a physical street address. A PO box alone does not satisfy the requirement.

Office identity requirement. The registered agent's business office must be identical to the registered office address listed in your filings.

Residency for individuals. Individual agents must be Missouri residents, age 18 or older.

Why Most People Choose Professional Service

Serving as your own registered agent (or asking a friend to do it) creates practical challenges:

• The address goes on public record with the Secretary of State — searchable by anyone
• Someone must be physically present at that address during business hours every weekday
• A missed service of process delivery can result in a default judgment against your business
• Relocating means filing an update with the state ($10-$25 fee each time)
• Process servers arrive at your door during work hours

Professional service eliminates all of these issues for $99/year.
