Out-of-State Business Operating in Montana? Register Here First.

When an LLC or corporation formed elsewhere starts doing business in Montana, Montana's Secretary of State calls it a "foreign" entity. Such an LLC needs a certificate of authority before it transacts business here (MCA 35-8-1001), and its application names a Montana registered agent.

Montana Registered Agent.co provides that local presence for $99/year.

When Registration Is Required

Montana's LLC Act doesn't define transacting business. MCA 35-8-1001 gives a non-exhaustive list of activities that don't count:

• Bringing, defending or settling a proceeding
• Member or manager meetings and the company's other internal affairs
• Having a bank account
• Running a transfer or registration office for the LLC's own securities, or using a trustee or depositary to hold them
• Using independent contractors to sell
• Orders by mail, employees, agents or other means that need acceptance outside Montana before they're contracts
• Borrowing, lending, or placing a mortgage or lien on property
• Pursuing or securing a debt, including foreclosing on what backs it
• Holding real or personal property picked up while collecting a debt, if it's sold within 5 years, earns no income, or isn't used in the business
• A one-off transaction finished within 30 days that isn't one of a run of similar ones
• Interstate commerce

Two Montana-specific points: a contract with the state, a state agency or a local government counts as transacting business, and the Secretary of State's help center says an out-of-state business with a physical presence or significant operation here, such as an employee working remotely from Montana, generally needs to register. Consult a business attorney if your situation falls in a gray area.

What "Foreign" Means

Not international. In entity law, "foreign" means formed under the law of another state, tribe or country. A Wyoming LLC with Montana operations is a foreign LLC here. A Delaware corporation with Billings employees is a foreign corporation from Montana's perspective.

The Registration Process

Step 1: Check where you stand at home. The application includes a statement that your LLC has complied with the laws of the state where it was organized and exists there (MCA 35-8-1003). The statute's list for the application doesn't include a certificate of good standing, but keep your home-state filings current so the statement is true.

Step 2: Appoint a Montana registered agent. Montana's Model Registered Agents Act recognizes two types: commercial agents that file a listing with the state, and noncommercial ones, which can be a person or a domestic or foreign business serving a particular company. The Secretary of State says the agent needs a physical Montana address, not a P.O. box, and should be available during business hours. We satisfy all requirements.

Step 3: File for a Certificate of Authority. Montana files business documents online only: sign in at biz.sosmt.gov, open Forms, and choose the foreign form for an LLC. The state fee is $70 (plus $50 for each series named in a series LLC), paid by card or e-check. The application lists your LLC's name, home jurisdiction, date of organization and duration, principal office mailing address, registered agent, and managers if they differ from the members. If your name lacks an LLC ending, you can add "limited company," "l.l.c." or "l.c." for Montana; if it's unavailable, you can use an assumed business name filed with the Secretary of State.

Step 4: Await processing. You'll get an email once the office approves the filing. The Secretary of State doesn't publish a standard turnaround; 24-hour handling costs $20 and 1-hour handling $100.

Step 5: Maintain compliance. Your annual report window runs from January 1 to April 15 every year; keep your registered agent current, and handle Montana tax obligations for as long as you operate here. A report filed after April 15 costs $35, and a report more than 140 days late, or 60 days without a registered agent, is grounds for revoking your certificate after a 60-day notice. Withdrawing later has no state fee but needs a Department of Revenue tax certificate.

Consequences of Skipping Registration

Under MCA 35-8-1002, a foreign LLC that transacts business in Montana without a certificate of authority:

• Can't maintain a proceeding in a Montana court before it obtains the certificate, and a judge may stay its case in the meantime
• Is liable for a civil penalty of $5 a day, up to $1,000 a year, which the attorney general may collect
• Risks having a contract with the state or a local government voided

Its acts stay valid, and it can still defend a lawsuit in Montana.

Why Foreign Entities Need a Dependable Local Agent

You are managing Montana compliance remotely. A missed document or overlooked deadline has amplified consequences when you cannot personally check a Montana mailbox. A reliable agent closes that gap:

• Documents scanned and forwarded the same day they arrive, no matter where you are
• Annual report reminders before the April 15 deadline
• Secure portal access from any state, any device
• A physical Montana street address on file as your agent
• $99/year flat rate, the same as domestic entities

Montana's Advantages for Foreign Entities

• The annual report's standard $20 fee is waived for on-time filings through 2027, so filing by April 15 currently costs $0
• No state sales tax
• Changing your registered agent costs nothing (no state fee)
• Model Registered Agents Act provides clear, predictable rules

Combined with our $99/year service, the total ongoing compliance cost for a foreign-qualified entity in Montana is just $99/year through 2027 while the on-time report fee is waived (file late and the state charges $35).

Those figures cover the years after you are registered. Getting registered in the first place costs $199 for our filing work plus the state's $70 fee for an LLC or corporation, a one-time charge that also covers your first year of our agent service.
