Want to start a C Corporation in Montana? The process begins with filing Articles of Incorporation with the Montana Secretary of State. Swyft Filings’ Basic Montana C Corporation formation package covers the essentials, including a name availability check, preparation and filing of your Articles of Incorporation, and ongoing support, all for a $0 service fee. You only pay Montana’s required $35 state filing fee. For additional support, you can upgrade to a paid package that may include corporate bylaws, stock authorization, EIN assistance, support for multiple share classes, and registered agent services available as an add-on.
Forming a Montana C Corp starts with choosing an available compliant C Corp name and appointing a registered agent to receive official documents for the company.
Next, determine your corporation’s share structure and file the Articles of Incorporation with the Montana Secretary of State. After your corporation is approved, adopt corporate bylaws, hold the initial organizational meeting, issue shares to the owners, and obtain an EIN to complete the setup.
Step 1: Choose a Name for Your Montana C Corporation
Before forming your Montana C Corporation, you need to choose a corporate name that meets the state's naming requirements. Under Montana law, your corporation's name must:
Use a corporate designator: Must include “Corporation,” “Incorporated,” “Company,” or “Limited,” or an allowed abbreviation such as “Corp.,” “Inc.,” “Co.,” or “Ltd.”
Make the name distinguishable: Must be distinguishable from relevant business names and other protected names already recorded with the Montana Secretary of State.
Don't rely on minor differences: Changing punctuation, adding or removing “Inc.,” or making other minor alterations may not make an otherwise similar name distinguishable.
Don't use misleading or deceptive language: Your name shouldn't falsely suggest an unauthorized corporate purpose or create a misleading impression about your business or its affiliation with another organization.
Now that you know the naming rules, start by coming up with a few potential names that reflect your business and are easy for customers to remember. You can also use Swyft Filings' free Business Name Generator to shortlist some better name ideas for your C Corp.
Then, search the Montana Secretary of State's online business portal to see whether your preferred name is already in use. The search can help you identify existing businesses with identical or similar names.
Yes. File a Name Reservation through the SOS Business Filing Portal for a \$10 fee, which holds your chosen name for 120 days while you finish preparing your formation paperwork. This is a smart move if you need time to line up a registered agent, finalize your share structure, or coordinate with co-founders before you are ready to file.
Yes. AI can help you brainstorm Montana C Corporation names by generating ideas based on your industry, audience, location, or brand style. You can also use the Swyft Filings free business name generator to explore name ideas. However, an AI-generated name isn't automatically available, so you should check it with the Montana Secretary of State before using it.
Search the Montana Secretary of State's business records to see whether your preferred name is already registered or is too similar to an existing business name. You should also check federal trademark records before settling on the name. A name being available for Montana registration doesn't necessarily mean it is free to use as a trademark.
If your Montana C Corp wants to conduct business under a name other than its legal corporate name, you can file a DBA with the Montana Secretary of State. Before filing, check that the name is available and does not conflict with an existing business name. Registering a DBA allows your corporation to operate under an alternate name, but it does not create a separate business entity or provide a separate liability shield.
Nothing is wrong with skipping name reservation if you are prepared to file your C Corporation formation documents. You can check the name's availability and submit your Articles of Incorporation to the Montana Secretary of State. Once the filing is approved, the corporation is registered under that name.
Step 2: Appoint a Montana Registered Agent
Every Montana corporation must maintain a registered agent with a physical street address in Montana for as long as it's active. This person or entity is the official point of contact for lawsuits, subpoenas, and state correspondence.
Individual agents must be Montana residents with a physical in-state street address. A P.O. box is not acceptable under Montana law.
Entity agents (a company acting as the registered agent) must be authorized to do business in Montana.
Availability during normal business hours to accept legal and state documents is expected of any agent, individual, or entity.
A third-party registered agent service can help protect your privacy by keeping your home address private and reducing the risk of legal documents being served at an inconvenient time or in front of clients, employees, or family. Swyft Filings' registered agent service can serve as your Montana corporation's registered agent.
Yes. You can serve as your own registered agent if you meet Montana's requirements. You must be a Montana resident with a physical street address in the state and be available during normal business hours to receive legal and official documents. A P.O. box alone is not sufficient. You can also appoint an eligible individual or choose Swyft Filings' registered agent service to handle this responsibility.
A registered agent is required so your Montana C Corp has a reliable point of contact for receiving lawsuits, subpoenas, tax notices, and other official state documents. The agent must maintain a physical street address in Montana where these documents can be delivered during normal business hours. Keeping a registered agent on record also helps your corporation remain in compliance with Montana's business requirements.
No. Montana requires a registered agent to have a physical street address in the state where legal and official documents can be delivered. A P.O. box alone cannot serve as the registered agent's address.
A Montana C Corporation must maintain a registered agent while it is active. If your corporation does not have one, it may fall out of compliance with state requirements and could face administrative consequences. Keeping your registered agent information up to date helps ensure your business can receive important legal and state documents.
You can change your Montana C Corp's registered agent by filing a Statement of Change with the Montana Secretary of State. There is no filing fee for this change. If your annual report is due, you can also update your registered agent information when filing the annual report instead of submitting a separate form. Don’t want to handle it on your own? Swyft Filings' change registered agent service can handle this responsibility for your business.
Step 3: Set Your Montana C Corp Share Structure
Montana does not require you to use a complicated share structure when forming a C Corp. You can set up the corporation around the ownership and funding needs of your business, whether you are starting with a small group of founders or planning to bring in investors later. Before submitting your Articles of Incorporation, decide how many shares the corporation will be authorized to issue and whether you will create one or more classes of stock.
For a Montana C Corp, consider these points:
Set your authorized share count: Decide how many shares your Montana C Corp can issue. The state's filing fee does not change based on the number of authorized shares.
Define your stock rights: Decide whether you'll create multiple stock classes or include provisions for cumulative voting or preemptive rights in your Articles of Incorporation.
Consider a close corporation: If the business will be owned by a small, closely held group, determine whether Montana's close corporation provisions fit your structure.
Keep shares available: Consider leaving some authorized but unissued shares available for future investors, employees, or other equity needs.
A Montana C Corporation can authorize shares of stock and divide them into one or more classes or series. The Articles of Incorporation can establish details such as the number of shares, different classes of stock, voting rights, and certain shareholder rights. Founders should decide on the structure before filing so the corporation's ownership and equity plan are clear from the start.
Multiple stock classes can give different groups of shareholders different rights. For example, a corporation may use common stock for founders and employees while creating another class with different voting or economic rights for investors. The right structure depends on the corporation's ownership, financing plans, and governance needs.
After forming the corporation, the founders can receive shares in accordance with the ownership arrangement approved by the corporation. The corporation should document the issuance through its organizational records, including the number and type of shares issued to each founder. Founders should also review any applicable vesting, purchase price, voting, or tax considerations before the shares are issued.
Step 4: File Your Montana Articles of Incorporation
Montana only accepts Articles of Incorporation online. There are no mail, fax, or in-person filing options for this document. So, start by gathering the information you will need for the Montana filing, such as:
Corporate name
Principal office information
Registered agent information
Authorized shares and applicable stock provisions
Incorporator information
Any optional provisions you want included in the Articles
Montana's Secretary of State notes that information submitted through its business filing system is public, so review it carefully before submitting.
Now that you have all the information, let’s discuss steps on how to file a Montana Articles of Incorporation for the C corporation online.
Open the Forms section available on the left side.
Under the available entity types, select Profit Corporations.
Choose the Articles of Incorporation for the Domestic Profit Corporation option, then select File Online to begin your application.
Complete the required information in the Articles of Incorporation. Fields marked with a red asterisk must be completed before you can submit the filing.
Review all the information carefully to make sure your corporation's name, registered agent details, share information, and other filing details are accurate.
Submit the completed Articles through the online portal and pay the \$35 Montana filing fee. The portal accepts payment by credit or debit card or e-check.
After submitting your application, you can track the status of your filing and monitor any updates from the Secretary of State.
You can file your Montana C Corporation's Articles of Incorporation online through the Montana Secretary of State's business filing portal. Create or sign in to your account, open the Forms section, select the appropriate Domestic form, and choose Profit Corporations. Then select the Articles of Incorporation form for a domestic profit corporation, complete the required fields, pay the filing fee, and submit the application for review.
The Montana Secretary of State currently charges \$35 to file Articles of Incorporation for a domestic profit corporation. The filing fee is paid when you submit the application through the state's online filing portal.
When filing Articles of Incorporation for a Montana C Corp, you will need to provide the corporation’s legal name, number of authorized shares, registered office address, registered agent’s name and address, and the name and address of each incorporator. Montana’s online filing system identifies required fields with a red asterisk.
Montana has moved its business filing system to online-only filing, so you generally won't use a paper PDF to submit your Articles of Incorporation. The Secretary of State's online portal provides the applicable form.
No. Montana's Secretary of State has moved business filings to an online-only system, so Articles of Incorporation for a Montana C Corp cannot currently be submitted by mail as a paper filing. You must use the state's online business filing portal to submit the formation documents.
Step 5: Adopt Bylaws for Your Montana C Corp
After your Montana C Corp is officially formed, put its internal governance rules in place by adopting corporate bylaws. Think of bylaws as the company's rulebook; they can address areas such as:
Define the number of directors, their roles and terms, and how vacancies are filled.
Set out the duties and authority of the president, secretary, treasurer, and other officers.
Establish procedures for shareholder and board meetings, including notice requirements and voting.
Explain how corporate actions are approved and how votes are counted.
Set rules for shareholder records, voting rights, and other ownership-related procedures.
Establish who may amend the bylaws and what approvals are required.
Once the board or incorporators formally adopt the bylaws, keep a signed or otherwise properly documented copy in the corporation's records. If you are not aware of how to do all of these, choose Swyft Filings' paid Montana C Corp formation service package, where our professionals will help with the preparation of customized Corporate Bylaws for you as part of the package.
Under Montana Code Annotated § 35-14-206, the incorporators or board of directors of a Montana corporation must adopt initial bylaws. The bylaws can establish the corporation's internal rules, provided they do not conflict with Montana law or the Articles of Incorporation. They may cover matters such as corporate governance, meetings, voting, director and officer responsibilities, and procedures for managing the corporation.
No. Montana C Corp bylaws are internal corporate documents and are not filed with the Secretary of State. After adopting them, the corporation should keep the bylaws with its official business records.
Montana law requires the incorporators or board of directors to adopt initial bylaws, so a corporation should not simply operate without them. Failing to adopt bylaws can leave the corporation without clearly documented rules for governance and decision-making, creating uncertainty in matters such as board actions, shareholder rights, meetings, and officer responsibilities. The better approach is to adopt bylaws after incorporation and maintain them with the corporation's records.
MCA § 35-14-206 requires the incorporators or board of directors to adopt the corporation's initial bylaws. It also states that bylaws may contain provisions that are consistent with Montana law and the corporation's Articles of Incorporation. Montana law specifically allows bylaws to address certain shareholder proxy and expense-reimbursement provisions related to director elections.
Step 6: Hold Your Organizational Meeting
After your Montana C Corp is formed and the bylaws are adopted, hold an initial organizational meeting to officially put the corporation into operation.
During the organizational meeting, you can:
Confirm the board of directors: Approve or confirm the initial directors responsible for overseeing the corporation.
Appoint officers: Formally appoint officers such as the president, secretary, and treasurer and define their responsibilities.
Adopt the bylaws: Formally approve the corporation's bylaws if they have not already been adopted.
Approve stock issuance: Authorize the initial issuance of shares to founders or other shareholders.
Approve banking arrangements: Authorize the corporation to open and operate its business bank account.
Approve key agreements: Review and approve important contracts, leases, or other arrangements entered into on behalf of the corporation.
For a small Montana C Corp, the meeting need not be complicated. The important point is to properly document the decisions that establish the corporation's governance and initial operations.
After incorporation of your C Corp, the organizational meeting is used to complete the corporation's initial setup. If the Articles of Incorporation name the initial directors, the directors hold the meeting; otherwise, the incorporator or incorporators hold it to elect the initial directors or board. Under Montana law, the meeting can be used to adopt bylaws, appoint officers, elect directors when necessary, and handle other startup business.
Have the corporation's Articles of Incorporation, proposed bylaws, initial director and officer information, and share issuance details ready for the meeting. You should also prepare an agenda and a record of the actions approved during the meeting. Afterward, keep the meeting minutes or written consents with the corporation's records.
There is no single state-required minutes template that every Montana C Corp must use. Your minutes should clearly document the corporation's name, meeting date, participants, and the decisions made. Depending on the circumstances, the record may include approval of the bylaws, election or confirmation of directors, appointment of officers, authorization of stock issuance, and other organizational actions.
Failing to complete the organizational process can leave important corporate decisions undocumented and create governance or recordkeeping issues. Also, it makes it harder to document who has authority to act for the corporation, to approve stock issuances, to establish banking authority, or to demonstrate that the required corporate formalities were followed.
Step 7: Apply for Your EIN
Once your Montana C Corp is officially formed and you have completed its initial organizational steps, the last thing to do is obtain an Employer Identification Number (EIN) from the IRS. You can apply for an EIN directly through the IRS. Have your corporation's formation information ready, including:
Legal business name: Use the exact name approved by Montana.
Responsible party: Provide the required information for the individual responsible for the corporation.
Business structure: Identify the business as a corporation.
Formation details: Keep your Montana incorporation information available.
Reason for applying: Select the reason that best describes why you're requesting the EIN.
The IRS generally issues an EIN immediately when you apply online, provided the application is completed successfully. Keep the EIN confirmation notice with your corporation's permanent records because you will use the number for federal tax and other business purposes. Want professionals to handle this for you? Let Swyft Filings apply for an EIN as part of our paid Montana C Corporation formation service package.
You'll need it to open a business bank account, hire employees, file federal and Montana corporate income tax returns, and apply for most local business licenses. If you plan to open a business bank account, also budget time to request a Certificate of Existence dated within the past six months, which most banks will ask for alongside your EIN confirmation.
You should obtain an EIN before opening a bank account for your Montana C Corp. While the exact requirements can vary by financial institution, the IRS recognizes obtaining an EIN for banking purposes, and many banks require an EIN when opening a business account for a corporation.
Yes. Not having employees does not eliminate the EIN requirement for a C Corp. The IRS states that corporations need an EIN even when they have no employees. You should apply after your Montana corporation has been legally formed and use the EIN for the corporation's federal tax and reporting requirements
What Are the Post-Formation Requirements for a Montana C Corp?
After your Montana C Corp is formed, you still have a few ongoing responsibilities to handle. These requirements help establish the corporation as a separate business, prepare it for tax and banking purposes, and keep its state registration current.
1. File Your Montana Annual Report
Montana corporations must file an Annual Report with the Montana Secretary of State each year. The report keeps the state's records current and gives your corporation an opportunity to review or update information such as its registered agent, business address, principals, and share details.
When preparing your annual report:
Review your corporation's information before submitting the filing.
Update your registered agent or business details if anything has changed.
Submit the report by Montana's applicable annual filing deadline.
Keep a copy of the completed filing with your corporate records.
You can manage many corporation filings through the Montana Secretary of State's Business Search and Filing Portal. To locate your corporation and its filed documents:
Search for your corporation using the business search.
Click the entity name in the search results to open its business record.
Open the corporation's record.
Select the "File Annual Report" button.
Follow the online instructions to review your information and complete the filing.
2. Plan for Montana Corporate Income Tax
A Montana C Corp is taxed as a separate business entity. Montana's general corporate income tax rate is 6.75%, and state rules include a \$50 minimum tax. Your corporation may also have federal corporate income tax obligations.
As you prepare for corporate taxes:
Track revenue, deductible expenses, and other financial activity throughout the year.
Keep receipts, invoices, payroll records, and supporting tax documents organized.
File the applicable Montana corporate income tax return.
File the corporation's required federal income tax return.
Budget for estimated tax payments when they apply.
Consider professional tax guidance if the corporation operates or earns income in multiple states.
3. Check Montana Licensing Requirements
Montana does not issue one general statewide business license that covers every corporation. General business licensing is typically handled by cities and counties, while Montana agencies regulate certain professions and industries.
Depending on your business, check for:
City or county business licenses.
Professional or occupational licenses.
Industry-specific permits or registrations.
Building, zoning, or location approvals.
Health, agriculture, alcohol, contractor, or other regulated-industry permits.
License renewals required after your business begins operating.
Feeling unsure about which licenses apply? Swyft Filings' business license research service can review your business details against federal, state, and local requirements and provide information on the licenses and permits your business may need, along with direct application links.
4. Open a Montana C Corporation Bank Account
A dedicated business bank account helps your Montana C Corp keep corporate money separate from shareholders' personal funds. It also gives you a cleaner record of revenue, expenses, payroll, tax payments, and other business transactions.
Your bank may ask for:
Your filed Articles of Incorporation.
The corporation's EIN.
Corporate bylaws.
Identification for authorized account holders.
A corporate resolution authorizing the account or account signers, if required.
Additional ownership or business information requested by the bank.
Once the account is open, use it consistently for corporate transactions rather than mixing business and personal funds.
5. Register for Employer Taxes If You Hire Employees
Hiring employees creates additional state responsibilities. A Montana corporation that pays Montana wages must generally register for a state withholding tax account, and businesses subject to unemployment insurance rules must register and file the required reports.
If your corporation hires employees:
Register for Montana wage withholding when required.
Collect the appropriate employee withholding forms.
Register for unemployment insurance if your corporation meets the applicable requirements.
Handling these requirements as your corporation grows can help you avoid missed filings and keep your Montana C Corp's business records organized.

Starting a Montana C Corp means filing Articles of Incorporation, appointing a registered agent, and staying current with the annual report. Swyft Filings has been helping businesses form and stay compliant since 2015. Our team knows the Montana Secretary of State requirements and can file your C Corp quickly, accurately, and in full compliance.
Yes. A Montana corporation can have a board consisting of one or more directors, so a small corporation can operate with a single director. Montana law also allows the same individual to hold more than one corporate office, such as president, secretary, or treasurer. Your Articles of Incorporation or bylaws can establish additional requirements.
No. Montana law does not require a corporation's directors to be Montana residents or shareholders unless the corporation's Articles of Incorporation or bylaws establish those qualifications. Your registered agent, however, must still satisfy Montana's separate registered agent requirements.
Yes, if the corporation meets the IRS eligibility requirements. An eligible C corporation can submit Form 2553 to elect S corporation tax treatment. S corporations generally must have no more than 100 shareholders, use eligible shareholders, and have only one class of stock. Making the election changes the corporation's federal tax treatment rather than creating a new Montana business entity.
Your corporation may need an amendment if important information in its Articles changes, such as certain stock provisions or other terms included in the original filing. After obtaining the approvals required under Montana law and your governing documents, file the applicable amendment through the Montana Secretary of State's business filing system. You can search for the corporation, open its record, select Filing Actions, and choose the appropriate filing.
The Montana Secretary of State may list a business as involuntarily dissolved when required filings or fees are missed or when the business fails to maintain a registered agent. Domestic Montana corporations are currently eligible to apply for reinstatement within five years of dissolution. Reinstatement generally requires completing missing annual reports, filing a reinstatement application, paying applicable fees, and obtaining a Montana Department of Revenue Title 15 Certificate when required.
