What Is a Registered Agent for a Montana Corporation?
A registered agent is a person or entity designated to accept service of process, official notices, and legal demands on behalf of a Montana corporation. Under MCA § 35-7-113, the registered agent is “authorized to receive service of any process, notice, or demand required or permitted by law to be served on the entity.” Montana adopted the Model Registered Agents Act — codified as Title 35, chapter 7 of the Montana Code Annotated — to govern all aspects of registered agent eligibility, appointment, duty, resignation, and change for every entity type, including corporations. The statute applies uniformly to domestic for-profit, domestic nonprofit, domestic professional, and registered foreign corporations.
The registered agent’s function is strictly a statutory compliance role. The agent holds no corporate office, does not manage the corporation’s day-to-day operations, and is not a general commercial representative. The duties codified in MCA § 35-7-114 are confined to forwarding process, notices, and demands to the entity at the address most recently provided, and keeping the information on file with the Secretary of State current. Alongside the agent, every Montana corporation must maintain a registered office — the physical Montana address where the agent may be personally served — filed continuously with the Secretary of State from formation through dissolution or withdrawal.
Is a Registered Agent Required for a Montana Corporation?
Every corporation that forms in Montana or registers to transact business in the state must designate and continuously maintain a registered agent and a registered office. MCA § 35-14-501 states that each corporation “shall continuously maintain in this state a registered office and a registered agent in compliance with Title 35, chapter 7.” The statute expressly defines “corporation” to encompass both domestic corporations and registered foreign corporations, so no category is exempt. The obligation attaches as soon as the Secretary of State files the corporation’s articles of incorporation or foreign registration statement and persists through dissolution, withdrawal, or termination.
The requirement applies to each of the following corporation types:
- Domestic for-profit corporations — organized under the Montana Business Corporation Act, MCA Title 35, chapter 14
- Domestic nonprofit corporations — organized under the Montana Nonprofit Corporation Act, MCA Title 35, chapter 2
- Domestic professional corporations — organized under the Montana Professional Corporation Act, MCA Title 35, chapter 4, which incorporates the Business Corporation Act by reference
- Foreign corporations — registered to do business in Montana by filing a foreign registration statement or certificate of authority
A lapse of 60 days or more without a registered agent or registered office is a ground for administrative dissolution of a domestic corporation under MCA § 35-14-1420 or administrative termination of a foreign corporation’s registration under MCA § 35-14-1511.
Who May Serve as a Registered Agent for a Montana Corporation?
Montana law divides registered agents into two categories: commercial registered agents and noncommercial registered agents. Under MCA § 35-7-102, a commercial registered agent is an individual or a domestic or foreign entity that has filed a commercial registered agent listing statement with the Secretary of State under MCA § 35-7-106. A noncommercial registered agent is any individual or domestic or foreign entity that serves as an agent for service of process but has not filed a commercial listing. Both types must keep a physical address in Montana available for service. The corporation itself may not serve as its own registered agent — the agent must always be a separate individual or entity.
Option A — Commercial Registered Agent — An individual or entity files a listing statement under MCA § 35-7-106 affirming that it is in the business of serving as a commercial registered agent and providing the address of a place of business in Montana. Professional registered agent companies typically operate under this designation. A single commercial filing allows the agent to accept appointments from any number of entities, and a single address-change filing under MCA § 35-7-110 automatically updates the records for every entity the agent represents.
Option B — Noncommercial Registered Agent — An individual residing in Montana, or a domestic or foreign entity authorized to do business in the state, may serve as a noncommercial registered agent. The agent’s name and Montana street address appear directly in the corporation’s registered agent filing. This approach is standard when an incorporator, officer, or director personally serves as agent.
Under MCA § 35-7-105, the filing of articles of incorporation or a foreign registration statement naming a registered agent constitutes “an affirmation by the represented entity that the agent has consented to serve.” Montana does not require a separate consent form filed with the state. Every filing must include an actual street address or rural route box number in Montana under MCA § 35-7-104; a mailing address may be added if it differs from the street address.
| Requirement | Permissible | Not Permissible |
| Address type | Physical street address or rural route box number in Montana | P.O. Box only |
| Service accessibility | Personal service during business hours | Solely a mailbox or forwarding service |
| Agent identity | Individual resident or separate domestic/foreign entity | The represented corporation itself |
| Location | Anywhere in Montana | Outside Montana |
Note: Montana draws an administrative distinction between commercial and noncommercial agents, but either category satisfies the legal requirement. A corporation that appoints a noncommercial agent should confirm that the individual keeps a Montana street address and remains available to accept service during normal business hours.
How to Designate a Registered Agent on Your Montana Certificate of Formation
The registered agent and registered office are designated within the corporation’s articles of incorporation at the time of filing. Under MCA § 35-14-202, a for-profit corporation’s articles must set forth “the street and mailing addresses of the corporation’s initial registered office and the name of its initial registered agent at that office.” For a nonprofit corporation, MCA § 35-2-213 requires the information specified in MCA § 35-7-105(1), achieving the same result. Because filing the articles constitutes an affirmation that the agent has consented to serve, the designated agent’s agreement must be secured before the formation documents are signed and submitted.
- Obtain consent from the intended registered agent before completing the articles. Montana does not mandate a separate consent form filed with the Secretary of State — the formation filing itself affirms consent.
- Complete the registered agent section of the articles of incorporation, listing the agent’s full legal name and the registered office’s street and mailing addresses in Montana.
- Verify that the address satisfies MCA § 35-7-104 — an actual street address or rural route box number, with a mailing address if different.
- Submit the completed articles to the Secretary of State by filing online through the Montana Secretary of State’s online filing portal or by mailing the documents to the Secretary of State, P.O. Box 202801, Helena, MT 59620-2801. In-person delivery is accepted at the State Capitol, Room 260, 1301 6th Avenue, Helena, MT 59620.
- Pay the applicable filing fee.
Montana employs different formation filings and fee amounts for each corporation type. The table below summarizes the formation filing and its cost, as published on the Business Services Filing Fees page.
| Corporation Type | Formation Document | Filing Fee |
| Domestic for-profit corporation | Articles of Incorporation (MCA § 35-14-202) | $35 |
| Domestic nonprofit corporation | Articles of Incorporation (MCA § 35-2-213) | $20 |
| Domestic professional corporation | Articles of Incorporation (MCA §§ 35-14-202, 35-4-111) | $35 |
| Foreign for-profit corporation | Foreign Registration Statement (MCA § 35-14-1503) | $70 |
| Foreign nonprofit corporation | Certificate of Authority (MCA § 35-2-822) | $15 |
Note: A domestic professional corporation pays the same $35 articles-of-incorporation fee as a standard for-profit corporation. The Montana Business Corporation Act applies to professional corporations except where the Professional Corporation Act provides otherwise, and no fee distinction exists between the two.
Registered Agent Requirements for Professional Corporations in Montana
A professional corporation formed in Montana is subject to the identical registered agent rules that govern standard for-profit corporations. MCA § 35-4-111 provides that “the Montana Business Corporation Act applies to professional corporations, domestic and foreign, except to the extent its provisions are inconsistent with this chapter.” The Montana Professional Corporation Act, codified at Title 35, chapter 4, contains no provisions addressing registered agents at all — no alternative eligibility criteria, no special forms, and no distinct fees. The standard rules under MCA §§ 35-14-501 and 35-7-105 therefore apply without modification.
The features that set a professional corporation apart from a standard for-profit corporation relate to who may own and manage the entity, not to how the entity designates its registered agent. Under MCA § 35-4-301, shares may be issued only to natural persons licensed to render a professional service permitted by the articles, to qualifying general partnerships, or to qualifying professional corporations. Under MCA § 35-4-207, at least one-half of the combined directors and officers — other than the secretary and treasurer — must be qualified persons licensed in the relevant profession. The corporate name must include “professional corporation” or the abbreviation “P.C.” under MCA § 35-4-206.
| Requirement | Standard For-Profit Corporation | Professional Corporation |
| Registered agent eligibility | MCA §§ 35-7-102, 35-7-105 | Identical |
| Consent required | Yes (affirmed by filing) | Identical |
| Registered office address | Physical Montana street address | Identical |
| Corporation may not be its own agent | Correct | Identical |
| Shareholder eligibility | No professional license required | Licensed natural persons, qualifying partnerships, or qualifying PCs only (MCA § 35-4-301) |
| Director/officer eligibility | No professional license required | At least half (excluding secretary and treasurer) must be licensed (MCA § 35-4-207) |
| Formation filing fee | $35 | $35 |
The Registered Agent’s Role in Corporate Governance and Legal Proceedings
The registered agent holds a specific, statutorily defined position within the framework of corporate governance. Its function is separate from — and should not be confused with — the responsibilities of the corporation’s directors, officers, and shareholders.
Primary Role — Designated Agent for Service of Process — Under MCA § 35-14-504, the corporation’s registered agent “is the corporation’s agent for service of process, notice, or demand required or permitted by law to be served on the corporation.” When a lawsuit is properly delivered to the registered agent at the registered office, service is perfected against the corporation, starting the clock on the corporation’s deadline to respond. The agent’s only statutory duty is to forward the documents to the entity at the most recently supplied address.
Substitute Agent — The Secretary of State — If the corporation has no registered agent, or the agent “cannot with reasonable diligence be served,” process may instead be sent by registered or certified mail to the corporate secretary at the principal office. If that method also fails — or if a foreign corporation has withdrawn its registration or had it terminated — the Secretary of State becomes the substitute agent on whom duplicate copies of the process may be delivered. The Secretary of State then forwards one copy by certified mail to the corporation at its last known address. Service is effected at the earliest of actual receipt, the date on the signed return receipt, or five days after mailing by the Secretary of State. The practical risk is real: when service routes through the Secretary of State, the corporation may miss it entirely, sharply increasing the chance of a default judgment.
Governance Implications — The board of directors bears responsibility for keeping a qualified registered agent and a compliant registered office continuously on file. Any change must be promptly reported using a statement of change under MCA § 35-7-108. A 60-day lapse triggers grounds for administrative dissolution or termination, a consequence that can deprive the corporation of good-standing status and the ability to conduct business in Montana.
Registered Agent Information in Corporate Bylaws
Montana law does not require a corporation to identify its registered agent or registered office anywhere in its bylaws. Under MCA § 35-14-206, the bylaws “may contain any provision that is not inconsistent with law or the articles of incorporation,” but no statutory provision mandates the inclusion of registered agent details. The legally operative designation of the registered agent resides in the articles of incorporation filed with the Secretary of State, and any subsequent change is accomplished by filing a statement of change — not by revising the bylaws.
Bylaws are internal governance documents. A corporation must maintain its current bylaws at its principal office under MCA § 35-14-1601, but bylaws are not filed with the Secretary of State, and amending them has no legal effect on the registered agent designation. Still, a corporation may find it useful to reference the registered agent in its bylaws as a practical governance measure — for example, to provide directors and officers with a centralized reference to the current agent, to establish an internal notification procedure when the agent or office changes, or to document the process for appointing a replacement agent after a resignation.
What Happens to a Montana Corporation Without a Registered Agent?
A Montana corporation that fails to maintain a registered agent or registered office faces administrative dissolution if domestic, or administrative termination of its registration if foreign. Under MCA § 35-14-1420, the Secretary of State may commence dissolution proceedings when a corporation “is without a registered agent or registered office in this state for 60 days or more.” For foreign corporations, MCA § 35-14-1511 sets out parallel grounds and a corresponding termination procedure.
The process follows a defined timeline. On or before September 1 each year, the Secretary of State compiles a list of corporations with one or more grounds for dissolution and serves each with written notice. Under MCA § 35-14-1421, a domestic corporation has 90 days after delivery of notice to correct the deficiency. For a foreign corporation under MCA § 35-14-1511, the cure period is 60 days. If the corporation fails to act, the Secretary of State signs a certificate of dissolution or termination and files it. An administratively dissolved corporation “may not carry on any business except that necessary to wind up and liquidate its business and affairs,” although the dissolution does not terminate the authority of any registered agent that was in place.
| Consequence | Statutory Authority |
| Administrative dissolution (domestic corporation) | MCA § 35-14-1421 |
| Administrative termination of registration (foreign corporation) | MCA § 35-14-1511 |
| Secretary of State becomes substitute agent for service of process | MCA § 35-14-504(3) |
| Corporation limited to winding-up activities only | MCA § 35-14-1421(4) |
| Risk of default judgment without the corporation’s knowledge | MCA § 35-14-504(2)–(3) |
Reinstatement — A dissolved domestic corporation may apply to the Secretary of State for reinstatement within five years under MCA § 35-14-1422. The application must confirm that the grounds for dissolution have been eliminated and that the corporate name still satisfies naming requirements. The corporation must also submit a certificate from the Department of Revenue showing all taxes are paid, the reinstatement filing fee ($30 for a for-profit corporation or $10 for a nonprofit), and all delinquent annual reports with a penalty of $35 per delinquent year. When granted, reinstatement relates back to the dissolution date, and the corporation resumes business as if the dissolution had never occurred.
How to Change a Registered Agent for a Montana Corporation
Any Montana corporation — domestic or foreign, for-profit, nonprofit, or professional — may change its registered agent by filing a statement of change with the Secretary of State under MCA § 35-7-108. The filing requires only the name of the corporation and the new information to take effect. A notable feature of Montana law is that the interest holders and governors of a domestic entity need not approve the filing of a statement of change — an authorized signer may file it directly. The change takes effect on filing, and Montana charges no fee for the filing, regardless of corporation type.
- Confirm that the new registered agent has consented to serve. Filing the statement of change constitutes an affirmation of the agent’s consent under MCA § 35-7-108(3).
- Prepare the statement of change, providing the corporation’s name and the new agent’s name and Montana street address.
- File the statement through the Montana Secretary of State’s online filing portal or by mail to the Secretary of State, P.O. Box 202801, Helena, MT 59620-2801. In-person filing is accepted at the State Capitol, Room 260, 1301 6th Avenue, Helena, MT 59620.
- No filing fee is required.
The uniform no-fee policy is confirmed on the Business Services Filing Fees page, which lists “Statement Of Change – Registered Office/Agent/Both” as no fee under both domestic and foreign filings.
| Corporation Type | Change-of-Agent Filing Fee |
| Domestic for-profit corporation | No fee |
| Domestic nonprofit corporation | No fee |
| Domestic professional corporation | No fee |
| Foreign corporation | No fee |
When a noncommercial registered agent itself changes its name or address, the agent files a separate statement of change for each represented entity under MCA § 35-7-109. A commercial registered agent files a single statement under MCA § 35-7-110 that updates the records for every entity it represents — a significant administrative advantage for agents serving many corporations.
A registered agent may resign at any time by filing a statement of resignation under MCA § 35-7-111. The resignation takes effect on the earlier of the 31st day after filing or the appointment of a new agent by the entity. The resigning agent must promptly notify the corporation of the filing date.

Montana Corporation Registered Agent Frequently Asked Questions
Can a Montana corporation serve as its own registered agent?
No. The registered agent must be a separate individual or entity — either a commercial agent listed under MCA § 35-7-106 or a noncommercial agent that is an individual or a domestic or foreign entity distinct from the represented corporation. Under MCA § 35-7-102, a noncommercial registered agent is defined as “a person that is not listed as a commercial registered agent … and that is an individual or a domestic or foreign entity that serves in this state as the agent for service of process of an entity.” The statutory framework requires the agent to be a person other than the corporation it serves.
Can a sole incorporator of a corporation serve as its registered agent?
Yes. A sole incorporator who is an individual residing in Montana and who maintains a physical Montana street address may serve as the corporation’s noncommercial registered agent. By filing the articles of incorporation with the agent’s name, the incorporator affirms under MCA § 35-7-105 that the agent has consented. The incorporator’s street address will appear in the public filing records maintained by the Secretary of State. No separate consent form is required.
Does a corporation need a registered agent separate from its officers and directors?
No. Montana does not require the registered agent to be someone other than a corporate officer or director. Any individual who resides in Montana and maintains a qualifying street address may serve, regardless of whether that person also holds a corporate office. The sole prohibition is that the corporation itself may not act as its own agent. The statutory designation of a registered agent does not override or substitute for other service-of-process methods permitted under Montana law.
Must a registered agent be designated before filing formation documents?
Yes. Under MCA § 35-14-202, the articles of incorporation must include the name of the initial registered agent and the street and mailing addresses of the initial registered office. The articles cannot be filed without this information. Because filing the articles constitutes an affirmation of the agent’s consent, the designated agent must agree to the appointment before the formation documents are signed and delivered.
Is the corporation’s registered agent required to be listed in the corporate bylaws?
No. Under MCA § 35-14-206, bylaws may contain any provision consistent with law and the articles, but no Montana statute requires registered agent information in the bylaws. The official designation is set forth in the articles of incorporation and is updated by a statement of change filed with the Secretary of State. Bylaws are internal governance documents maintained at the principal office and are not filed with the state.
Can I change my corporation’s registered agent online?
Yes. A statement of change may be filed electronically through the Montana Secretary of State’s online filing portal. There is no filing fee for a statement of change of registered agent or registered office, regardless of corporation type. The change takes effect on filing under MCA § 35-7-108(4). Paper filings sent by mail or delivered in person are also accepted.
Do Professional Corporations (PCs) have different registered agent requirements?
No. Under MCA § 35-4-111, the Montana Business Corporation Act applies to professional corporations except where the Professional Corporation Act provides otherwise. Because the Professional Corporation Act contains no provisions addressing registered agents, the standard rules apply in full. The differences between a professional corporation and a standard for-profit corporation relate exclusively to shareholder eligibility, director and officer licensing, and corporate name requirements under MCA Title 35, Chapter 4, not to registered agent obligations.
Can the same individual or service act as registered agent for multiple Montana corporations?
Yes. Montana law places no cap on the number of entities a single individual or service may represent. Commercial registered agents that file a listing statement under MCA § 35-7-106 routinely serve hundreds or thousands of entities. When a commercial agent relocates its office within Montana, a single filing under MCA § 35-7-110 automatically updates the records for every entity it represents, making multi-entity representation administratively efficient.
What happens if my corporation’s registered agent moves out of Montana?
The individual would no longer maintain a physical address in Montana as required by MCA § 35-7-104, rendering the appointment non-compliant. The corporation must promptly file a statement of change under MCA § 35-7-108 to appoint a new qualified agent. If the corporation remains without a registered agent or registered office for 60 days or more, the Secretary of State may commence administrative dissolution proceedings under MCA § 35-14-1420. If the agent relocates to a new address within Montana rather than leaving the state, a noncommercial agent may file a statement of change under MCA § 35-7-109 to update the address without requiring the corporation to submit a separate filing.
Is there a different registered agent fee for nonprofit corporations changing their agent?
No. Montana charges no filing fee for a statement of change of registered agent or registered office, regardless of whether the filing is made by a for-profit corporation, a nonprofit corporation, a professional corporation, or a foreign corporation. The Business Services Filing Fees page lists “Statement Of Change – Registered Office/Agent/Both” as having no fee for all corporation types under both the domestic and foreign filing categories.
