Missouri Registered Agent: Service and Requirements

Registered agent service for Missouri LLCs

Our registered agent service names our partner's Missouri agent on your LLC's record. The agent keeps a staffed street address in Missouri, accepts lawsuits and state mail in business hours, and forwards every document to you the same business day it arrives. Your own address stays off the agent line of the public filing, and the renewal reminder arrives 30 days before each year.

• Forming a new Missouri LLC: add the agent in the application; it is set up with the filing, so the company never goes a day without one.
• Already have a Missouri LLC: switch to our registered agent; we file Missouri's change-of-agent filing for you.
• Forming on America LLC Filing instead? You can add the agent while you form there.

Missouri's registered agent rules

Every state asks the same three things of the agent: a physical address in the state, a person there in business hours, and consent to serve. The details below are Missouri's, read on the state's own form and statute (RSMo 347.030); a row the state's pages did not confirm is left out rather than guessed.

The appointment is made on the Articles of Organization itself, so the agent has to be settled before you file. Naming someone who has not agreed leaves the company exposed if that person refuses papers; naming a PO box gets it returned.

What the Missouri agent actually receives

Three kinds of paper arrive at the agent's address, and each one starts a clock.

• Service of process. If the LLC is sued, the summons and complaint are delivered to the agent. The deadline to answer runs from that delivery, whether or not the owner hears about it, so an agent who is never there can cost the company a default judgment.
• State notices. Missouri's filing office writes to the agent about the company's record: confirmations, corrections and any notice that the company is out of compliance.
• Tax and agency mail. Some agencies and courts use the agent address as the company's address of record; garnishment orders and subpoenas for records arrive there too.

None of this is optional for the agent to receive, which is why the state cares who the agent is and where. The owner's job is to make sure whatever arrives reaches the right person the same day.

Can I be my own registered agent in Missouri?

Missouri lets an individual with a street address in the state serve as the agent, so an owner who lives in Missouri can name themselves. The job is simple but unforgiving: someone has to be at that address during normal business hours to accept a process server, and the state's notices (including the yearly report reminder) go there. Miss a lawsuit because nobody was home and a default judgment can follow.

It is free, and it is the right choice for an owner who works from a fixed Missouri address and does not mind that address being public. It is the wrong choice for an owner outside Missouri, one who moves often, or one who runs the business from home and would rather not publish that.

Three questions settle it. Will you be at one Missouri address in business hours for the life of the company? Are you comfortable with that address on a public record that data brokers copy? And if you move, will you remember to file the change before the state's mail starts bouncing? Three yeses and you are your own agent; one no and a service is the cheaper mistake to avoid.

Hiring a registered agent in Missouri

A commercial registered agent is a company with a staffed Missouri address that accepts papers for many companies and forwards them. The LLC lists the agent's address instead of the owner's, so the owner's address stays off the public filing and nobody has to keep office hours.

Our registered agent service puts our partner's Missouri agent and address on your filing, forwards legal and state mail to you the same business day, and sends a renewal reminder 30 days ahead. Nothing is charged at checkout; the first year's fee is charged when we appoint your agent. It comes ticked in the application with its yearly fee on the review screen, and you can untick it there. Once the agent is set up, you can turn renewal off from your order page.

Whoever you hire, check two things before the filing goes in: that the agent is authorized to act in Missouri, and that the address on the filing is the agent's staffed street address, not a mailbox. An LLC that already exists can switch to our agent at any time.

What becomes public in Missouri

Organizer name(s) and street address(es), registered agent. Members and managers are not listed. That is the practical reason owners who work from home hire an agent: the agent's address is what the public sees.

How to change your Missouri registered agent

The agent is not permanent. Missouri accepts a change at any time, and the new agent must meet the same street-address rule. File the change promptly if the agent moves or resigns: an LLC with no reachable agent can be penalized and eventually administratively dissolved.

1. Line up the new agent and get their consent.
2. File the Corp. 59 (01/2025), Statement of Change of Registered Agent and/or Registered Office by a Foreign or Domestic For Profit or Nonprofit Corporation or a Limited Liability Company and pay the $10 state fee.
3. Keep the old agent in place until the state records the change, then cancel their service so it does not renew.
4. Update the address on file with the IRS, your bank and any licensing agency that used the old agent address.

Processing follows the state's published timetable for the filing method you choose, online or by mail; we do not promise a date. The full 51-state comparison of forms, fees and portals is in How to change your LLC's registered agent. Or let us file it: we name our partner's Missouri agent and file the change.

If the agent resigns or you move

An agent can quit. Every state lets the agent file a resignation, and the agent's duty to the company ends a set number of days after it is filed, whether or not the company has found a replacement. A commercial agent resigns when the bill goes unpaid; an individual resigns when they move or lose patience. Either way the company, not the agent, is the one the state holds responsible for having a new agent on record.

Moving has the same effect from the state's side. If you are your own agent and move house, the address on the record is now wrong, and papers served there may never reach you. File the change (Corp. 59 (01/2025), Statement of Change of Registered Agent and/or Registered Office by a Foreign or Domestic For Profit or Nonprofit Corporation or a Limited Liability Company) as soon as the new address is fixed; a mail forward is not a substitute, since process is handed to a person, not posted.

If the LLC fails to appoint or maintain a registered agent, the Secretary of State is deemed its agent for service of process while the default exists (RSMo 347.033(3)). The fix is always the same filing: name a reachable agent and record it with the state.
