What Is a Foreign Filing Entity in Missouri?
A foreign entity in Missouri is any business organization formed under the laws of a jurisdiction other than Missouri — whether that jurisdiction is another U.S. state or a country outside the United States. Missouri’s General and Business Corporation Law, codified in RSMo Chapter 351, governs foreign corporations, while separate chapters address foreign LLCs (Chapter 347), foreign limited partnerships (Chapter 359), foreign LLPs (Chapter 358), and foreign nonprofit corporations (Chapter 355). Under RSMo § 351.572, a foreign corporation “may not transact business in this state until it obtains a certificate of authority from the secretary of state.” Each of the other chapters imposes an equivalent obligation on its respective entity type.
Registration with the Missouri Secretary of State is only the first step. Every registered foreign entity must also continuously maintain a registered agent and a registered office in Missouri for as long as its registration remains active. The registered agent serves as the entity’s designated point of contact for service of process, official notices, and government correspondence. Under RSMo § 351.370, every corporation — foreign or domestic — must keep both a registered office and a registered agent in the state at all times. Identical obligations apply to foreign LLCs under RSMo § 347.030 and to foreign LLPs under RSMo § 358.470. Losing either the agent or the office can set in motion proceedings that result in revocation or cancellation of the entity’s Missouri registration.
Which Out-of-State Entities Are Required to Register in Missouri?
Every type of foreign business organization that intends to conduct intrastate business in Missouri must register with the Corporations Division of the Secretary of State before beginning operations. Missouri does not limit this obligation to one or two entity types; it extends to the full range of business structures the state recognizes. The following foreign entity types must register:
- Foreign for-profit corporations (RSMo Chapter 351)
- Foreign nonprofit corporations (RSMo Chapter 355)
- Foreign limited liability companies (RSMo Chapter 347)
- Foreign limited partnerships (RSMo Chapter 359)
- Foreign limited liability partnerships (RSMo Chapter 358)
- Foreign limited liability limited partnerships (RSMo § 359.172)
- Foreign professional corporations (RSMo Chapter 356, following the Chapter 351 qualification process)
- Foreign cooperative associations (RSMo Chapter 274, following the Chapter 351 fee schedule)
Missouri’s statutes address the concept of transacting business by listing activities that fall outside the registration requirement. Under RSMo § 351.572, a foreign corporation is not considered to be transacting business in Missouri solely because it maintains or defends a lawsuit, holds meetings of its board of directors or shareholders, maintains bank accounts, creates or acquires indebtedness, secures or collects debts, completes an isolated transaction within thirty days that is not part of a pattern of similar transactions, or conducts business in interstate commerce. The statute specifies that this list “is not exhaustive.” A parallel set of excluded activities for foreign LLCs appears in RSMo § 347.163. The Secretary of State does not make individual determinations about whether a particular entity’s activities amount to transacting business — each entity must evaluate its own situation and consult legal counsel as appropriate.
Registered Agent Requirements for Foreign Entities Under Missouri Law
The registered agent rules that govern foreign entities in Missouri are identical to those that apply to domestic entities. Under RSMo § 351.370, every corporation must have and continuously maintain both a registered office and a registered agent, and these requirements extend to foreign corporations that have obtained a certificate of authority. The same obligation appears in RSMo § 347.030 for LLCs and in RSMo § 358.470 for LLPs. Regardless of entity type, the eligibility criteria and address standards are uniform.
Option A — An Organization. A domestic Missouri corporation, a foreign corporation already authorized to transact business in Missouri, or (in the case of LLPs) the partnership itself may act as the registered agent. The organization’s business office must be at the same address as the entity’s registered office. The foreign entity that is applying for registration cannot serve as its own agent under the corporation and LLC statutes. Written consent from the successor agent must be obtained and either included on the change form or attached to it before the designation is filed.
Option B — An Individual. Any individual who resides in Missouri may serve as a registered agent, provided that the individual’s business office is at the same address as the entity’s registered office. Written consent to the appointment is required before the filing is submitted to the Secretary of State.
The consent requirement is woven into the change-of-agent filing rules. Under RSMo § 351.375, a statement changing a corporation’s registered agent must include “the successor registered agent’s written consent to the appointment either on the statement or attached thereto.” The same language appears in § 347.030 for LLCs.
| Requirement | Rule |
| Address type | Physical street address in Missouri |
| P.O. Box | Permitted only in conjunction with a physical street address; cannot be the sole address |
| Mailbox or telephone answering service | Does not satisfy the registered-office requirement |
| Relationship to the agent’s office | The registered office address and the registered agent’s business office must be identical |
| Availability | Must be available during normal business hours for personal delivery of service of process |
| State location | Must be within the state of Missouri |
The registered agent and registered office must remain in place without interruption for as long as the foreign entity holds active registration.
How to Designate a Registered Agent When Registering a Foreign Entity in Missouri
A foreign entity designates its Missouri registered agent as part of the application it files with the Corporations Division to obtain authorization to transact business in the state. Every registration form — for corporations, LLCs, limited partnerships, LLPs, LLLPs, and nonprofit corporations — includes a dedicated line requiring the applicant to supply the agent’s name and Missouri street address. The designation is embedded in the registration filing itself rather than submitted as a separate document.
- Select an eligible registered agent. The agent must be either an individual who resides in Missouri or a corporation authorized to transact business in the state. The foreign entity filing for registration cannot act as its own agent under the corporation and LLC chapters.
- Obtain the agent’s written consent to serve. The consent may appear directly on the registration form or be attached as a separate page. Missouri does not publish a standalone consent form; the written consent is included with the filing.
- Complete the registered agent section of the registration form with the agent’s full legal name and Missouri street address. A P.O. Box may appear only alongside a physical street address.
- File the completed application with the Corporations Division. Filings may be submitted by mail to PO Box 778, Jefferson City, MO 65102, delivered in person to 600 W. Main St., Room 322, Jefferson City, MO 65101, or submitted online through Missouri Business Filings for entity types that support electronic filing.
- Pay the applicable filing fee. Refer to the registration forms table in the next section for the fee that applies to each entity type.
Note: A foreign corporation or foreign LLC that has been transacting business in Missouri without registration is subject to a fine of not less than $1,000 under RSMo § 351.574 and RSMo § 347.163, respectively, and cannot maintain any lawsuit in a Missouri court until it registers.
Registration Forms by Entity Type for Foreign Entities
Each type of foreign entity files a specific application form and pays a specific fee to register with the Missouri Secretary of State. All forms are available for download from the Fees & Forms page maintained by the Corporations Division.
| Entity Type | Form | Filing Fee |
| Foreign for-profit corporation | Application for Certificate of Authority (Corp. 42) | $155 |
| Foreign nonprofit corporation | Application for Certificate of Authority (Corp. 55A) | $25 |
| Foreign LLC | Application for Registration (LLC 4) | $105 |
| Foreign limited partnership | Application for Registration (LP 42) | $105 |
| Foreign LLP | Application for Registration (LLP 1) | $55–$105 |
| Foreign LLLP | Application for Registration (LP 25) | $30–$105 |
Foreign LLP fees depend on the number of partners at the time of the application: two partners pay $55, three partners pay $80, and four or more partners pay $105. Foreign LLLP fees are calculated at $5 plus $25 per general partner, with the total capped at $105. The for-profit corporation fee of $155 includes a $5 Technology Trust Fund charge and a $150 qualification fee.
Every foreign corporation, foreign nonprofit corporation, foreign LLC, and foreign limited partnership must attach a current certificate of good standing or certificate of existence from the entity’s home jurisdiction. The certificate must be dated within sixty calendar days of the Missouri filing date.
Note: Electronic payments made through the Missouri Secretary of State’s online system incur a small convenience fee that is not collected or retained by the state.
What Happens If a Foreign Entity Fails to Maintain a Registered Agent in Missouri?
The Missouri Secretary of State may initiate proceedings to revoke a foreign entity’s certificate of authority — or cancel its registration — when the entity is without a registered agent or registered office for thirty days or more. Under RSMo § 351.598, the grounds for revocation of a foreign corporation’s certificate include operating without a registered agent for thirty days, failing to inform the Secretary of State of a change or resignation, or failing to file annual registration reports. Parallel grounds exist for foreign nonprofit corporations under RSMo § 355.806, for foreign LLCs under RSMo § 347.183, and for foreign LLPs under RSMo § 358.470.
The revocation process for foreign corporations proceeds as follows:
- The Secretary of State serves the foreign entity with written notice identifying the grounds for revocation. Service is made under RSMo § 351.594, typically by certified mail to the entity’s secretary at its principal office.
- The entity has sixty days after service is perfected to correct the deficiency or demonstrate that the grounds do not exist.
- If the entity fails to cure within sixty days, the Secretary of State signs a certificate of revocation, files it, and serves a copy on the entity.
| Consequence | Authority |
| Loss of authority to transact business in Missouri | RSMo § 351.602 |
| Inability to maintain any lawsuit in the Missouri courts | RSMo § 351.574 |
| Fine of not less than $1,000 for transacting business without a certificate | RSMo § 351.574 |
| Secretary of State becomes the entity’s substitute agent for service of process | RSMo § 351.602 |
| Registered agent’s authority is not terminated by revocation | RSMo § 351.602 |
A foreign corporation whose certificate has been revoked may seek reinstatement under RSMo § 351.604. The application must include a certificate from the Missouri Department of Revenue confirming that all taxes have been paid or a payback plan arranged, and the entity must pay a $50 reinstatement fee plus any delinquent fees, penalties, and charges. Foreign LLCs may apply for rescission of cancellation under RSMo § 347.183, paying a $100 reinstatement fee plus delinquent amounts.
How to Change a Registered Agent for a Foreign Entity Registered in Missouri
A foreign entity registered in Missouri may change its registered agent, its registered office address, or both at any time by filing the appropriate statement with the Corporations Division. The process and form depend on the entity type, though the underlying mechanics are similar across all categories. The change takes effect upon filing with the Secretary of State.
For corporations and LLCs, the change is filed using Statement of Change of Registered Agent or Registered Office (Corp. 59). For limited partnerships and LLLPs, the filing uses Statement of Change of Registered Agent and/or Registered Office (LP 9). For LLPs, the change is governed by RSMo § 358.470, which uses its own fee structure.
- Obtain the new agent’s written consent. The consent must appear on the change form itself or be attached as a separate document.
- Complete the form with the entity’s legal name, the current agent’s name and address, the new agent’s name and street address, and a statement that the entity authorized the change.
- File the form by mail, in person, or through Missouri Business Filings.
- Pay the filing fee: $10 for corporations, nonprofits, LLCs, and limited partnerships. LLP change-of-agent fees are $37 for a combined agent-and-office change (plus $7 per additional LLP affected) or $22 for an office-address-only change (plus $7 per additional LLP).
If a registered agent changes the street address of their own business office, the agent may update the registered office address for every entity it represents by filing a single statement, provided the agent notifies each affected entity in writing. This agent-initiated process is authorized under RSMo § 351.375 for corporations and RSMo § 347.030 for LLCs.
Agent Resignation. A registered agent of a foreign corporation may resign by signing and delivering to the Secretary of State the original and two copies of a statement of resignation, under RSMo § 351.592. The resignation takes effect on the thirty-first day after the date the statement is filed, unless the entity appoints a replacement sooner. The filing fee for resignation is $10 for corporations, nonprofits, and LLCs. For LLPs, the resignation process carries a $10 fee, but the resignation does not become effective until 120 days after filing. If the LLP does not appoint a successor agent within that window, its registration is automatically cancelled under RSMo § 358.470.
Withdrawal and Termination of Foreign Entity Registration in Missouri
A foreign entity that stops conducting business in Missouri — or that ceases to exist in its home jurisdiction — must file the appropriate withdrawal or cancellation form to end its Missouri registration. Leaving the registration open without maintaining the required agent and office invites revocation and accumulating penalties. The forms and fees differ by entity type.
Voluntary Withdrawal — Foreign For-Profit Corporation. A foreign corporation still existing in its home state files Application for Certificate of Withdrawal (Corp. 48) with a $25 fee. The application must state that the corporation is no longer transacting business in Missouri, revoke its registered agent’s authority, appoint the Secretary of State as substitute agent for service of process, and provide a mailing address for forwarding any process. A Certificate of Tax Clearance from the Missouri Department of Revenue (Form 943) must accompany the filing. Under RSMo § 351.596, the corporation commits to notifying the Secretary of State of any address change for five years after withdrawal.
Voluntary Withdrawal — Foreign Nonprofit Corporation. A foreign nonprofit files Application for Certificate of Withdrawal (Corp. 49) with a $10 fee. A Certificate of Tax Clearance must also accompany the filing. The statutory requirements mirror those for for-profit corporations under RSMo § 355.801.
Cancellation — Foreign LLC. A foreign LLC files Articles of Cancellation (LLC 8) with a $25 fee. The form requires the LLC’s Missouri name, charter number, home jurisdiction, home-state name, and a mailing address for service of process.
Cancellation — Foreign Limited Partnership. A foreign LP files Certificate of Cancellation (LP 78) with a $25 fee. All general partners must sign.
Withdrawal — Foreign LLP. A foreign LLP files a written withdrawal notice under RSMo § 358.440(10) with a $20 fee. The notice must include the partnership name, last registration date, and a current street address.
Termination — Foreign Corporation Dissolved or Merged. When a foreign corporation has dissolved or merged in its home jurisdiction, a duly authenticated certificate from the home state’s filing authority may be filed with the Secretary of State. The filing fee for evidence of dissolution or merger is $25, as published in the Schedule of Fees and Charges.
Note: Both for-profit and nonprofit corporations must obtain a Certificate of Tax Clearance from the Missouri Department of Revenue before the Secretary of State will process a withdrawal application. The tax clearance is valid for sixty days from its issuance date.
| Entity Type | Form | Filing Fee |
| Foreign for-profit corporation | Corp. 48 — Certificate of Withdrawal | $25 |
| Foreign nonprofit corporation | Corp. 49 — Certificate of Withdrawal | $10 |
| Foreign LLC | LLC 8 — Articles of Cancellation | $25 |
| Foreign limited partnership | LP 78 — Certificate of Cancellation | $25 |
| Foreign LLP | Withdrawal Notice (RSMo § 358.440) | $20 |
| Foreign corporation — evidence of dissolution/merger | Filing Evidence of Dissolution or Merger | $25 |
Frequently Asked Questions: Foreign Entities and Registered Agents in Missouri
Does a foreign entity need a separate registered agent for Missouri, even if it already has one in its home state?
Yes. Missouri requires every registered foreign entity to designate a registered agent who independently meets Missouri’s eligibility standards. The agent must be either an individual who resides in Missouri and maintains a business office at the Missouri registered office, or a corporation authorized to transact business in Missouri with a business office at that address. An agent serving the entity in another state does not satisfy the Missouri requirement unless that same person or organization also qualifies under Missouri law. This obligation applies equally to foreign corporations, LLCs, limited partnerships, LLPs, and all other registered entity types under RSMo § 351.370 and corresponding chapter provisions.
What is the difference between a Certificate of Authority and a Certificate of Registration?
No single document name covers every entity type. Missouri uses the term certificate of authority for foreign for-profit corporations under RSMo Chapter 351 and for foreign nonprofit corporations under RSMo Chapter 355. Foreign LLCs, limited partnerships, LLPs, and LLLPs instead file an application for registration under their respective chapters. Both terms refer to the document that grants a foreign entity legal authorization to transact business in Missouri. The terminology differs by entity type, but the practical effect is the same — the filing confirms that the entity has satisfied all statutory prerequisites and may lawfully operate in the state. Current forms for each entity type are available on the Fees & Forms page.
Can a foreign entity use a P.O. Box as its Missouri registered office address?
No. Missouri requires the registered office to be a physical street address where the registered agent maintains a business office and where service of process can be personally delivered during normal business hours. A P.O. Box may appear only in conjunction with a physical street address — it cannot serve as the sole registered office address. A mailbox service or telephone answering service does not qualify. This restriction is reflected on every registration form published by the Corporations Division, including the Application for Registration (LLC 4), which explicitly requires a street address.
What happens if we close our Missouri office but our registered entity is still active?
No automatic withdrawal or cancellation takes place when a foreign entity shuts down a physical office in Missouri. As long as the entity remains registered with the Secretary of State, it must continue to maintain a registered agent and registered office in the state. If the entity has stopped transacting business, it should file the appropriate voluntary withdrawal or cancellation form. Leaving the registration open while failing to keep an agent in place can lead to revocation proceedings under RSMo § 351.598 and equivalent provisions for LLCs and partnerships.
Does registering a foreign entity in Missouri create a new legal entity?
No. Registration grants an existing foreign entity the legal authority to transact business in Missouri, but it does not form a new entity. The organization continues to be governed by the laws of its home jurisdiction for internal affairs. Under RSMo § 355.771, a foreign corporation with a valid certificate of authority enjoys the same rights as a domestic corporation of like character, yet Missouri “does not authorize this state to regulate the organization or internal affairs of a foreign corporation.” This principle applies regardless of whether the entity is a corporation, LLC, limited partnership, or any other type.
Is a foreign entity required to file annual reports with the Missouri Secretary of State?
Yes, but the requirement varies by entity type. All foreign for-profit corporations must file an annual registration report with the Secretary of State. The report is due at the end of the month in which the corporation obtained its certificate of authority. Filing fees are $20 online or $45 by paper, and late reports incur an additional $15 penalty for each thirty days of delinquency. Foreign nonprofit corporations file annual reports at $10 online or $15 by paper. Foreign LLPs must file an annual renewal of their registration at $105 plus up to $100 for added partners. Foreign LLCs and foreign limited partnerships do not file a separate annual report with the Secretary of State but may have reporting obligations with the Missouri Department of Revenue.
If my foreign entity’s registered agent in Missouri resigns, how long do I have to appoint a new one?
Yes, there is a defined period. For foreign corporations, the agent’s resignation becomes effective on the thirty-first day after the statement of resignation is filed with the Secretary of State, unless a new agent is appointed sooner, under RSMo § 351.592. The same thirty-day period applies to foreign LLCs under RSMo § 347.030. For foreign LLPs, the period is significantly longer — 120 days — under RSMo § 358.470, and if no successor agent is designated within that window, the LLP’s registration is automatically cancelled. In all cases, failing to appoint a replacement within the applicable period exposes the entity to revocation or cancellation proceedings.
Do I need a certificate of good standing from my home state to register in Missouri?
Yes. Every foreign corporation applying for a certificate of authority must deliver a certificate of existence or similar document “duly authenticated by the secretary of state or other official having custody of corporate records” in the home jurisdiction, under RSMo § 351.576. The certificate must be dated within sixty calendar days of filing. The same sixty-day requirement applies to foreign LLCs under RSMo § 347.153 and to foreign limited partnerships under RSMo § 359.501. Foreign nonprofit corporations must also submit a current certificate, as reflected on the Corp. 55A application form.
What is the filing fee to register a foreign LLC in Missouri?
Yes, there is a fixed fee. The filing fee to register a foreign LLC in Missouri is $105, paid when submitting the Application for Registration (LLC 4) to the Corporations Division. Electronic payments incur a small convenience fee not retained by the state. A foreign LLC that transacts business in Missouri without registering faces a fine of not less than $1,000 under RSMo § 347.163 and cannot maintain any lawsuit in Missouri courts until it registers. For filing fees applicable to other entity types, consult the Schedule of Fees and Charges published by the Secretary of State.
