Start Your Montana LLC in 7 Simple Steps

Form your Montana LLC with a $35 filing fee, lower than in all 49 other states.

By Edmond Hui · Last updated: October 2026

Filing an LLC in Montana costs $35 upfront and has a free annual report due April 15. Montana publishes no standard processing time. See breakdown below.

Montana publishes no standard LLC turnaround: its fee schedule prices expedited service but attaches no figure to the ordinary $35 filing

The Montana Secretary of State sells speed instead of promising it: $20 for 24-hour priority handling, and $100 for 1-hour expedite. Treat any specific day count you see quoted for Montana with suspicion. It didn't come from the state. Plan around the filing itself, and buy an expedite tier if your timing is genuinely fixed.

How to Form an LLC: Step-by-Step

  1. 1

    Choose Your Montana LLC Name

    Select a unique name ending with 'LLC,' 'Limited Liability Company,' or acceptable abbreviations. Check availability using Montana Secretary of State's business search tool. Your name must be distinguishable from existing Montana business entities.

    Pro tip: Reserve your name for 120 days with a $10 fee if you're not ready to file immediately.
  2. 2

    Appoint a Montana Registered Agent

    Designate a registered agent with a Montana street address to receive legal documents. This can be yourself, another person, or a professional service. The agent must be available during normal business hours and have a physical Montana address.

    Pro tip: A professional registered agent service puts its address, not yours, on the registered agent line of the public filing, and accepts legal papers during business hours.
  3. 3

    File Articles of Organization

    Submit Form LLC-1 to the Montana Secretary of State with the $35 filing fee. Include your LLC name, registered agent information, and principal office address. File online at sosmt.gov or mail to the Secretary of State's office.

    What You File in Montana

    In Montana, the formation document is the Articles of Organization, filed with the Montana Secretary of State, Business Services. The state filing fee is $35. Montana lets you fill in and file the Articles of Organization online. The form itself requires the LLC's name, the registered agent's name, the principal office address, the organizer's name, whether the LLC is member-managed or manager-managed and the LLC's duration.

    Processing Times

    • Online: Not published, Montana Secretary of State states no standard turnaround for online filings
    • Mail: Not published, Montana Secretary of State states no standard turnaround for mailed filings, and every state that comments says mail is slower than online
    • Expedited: $20 for 24-hour priority handling, and $100 for 1-hour expedite
    Pro tip: Online filing is faster and provides immediate confirmation of submission.

    Create an Operating Agreement

    Draft an operating agreement outlining ownership structure, management procedures, and member responsibilities. This page has not confirmed whether Montana law requires an LLC to have an operating agreement. A written agreement signed by every member is worth having either way: it records who owns what share, who makes decisions and how profits are divided.

    Pro tip: Even single-member LLCs benefit from an operating agreement to maintain separation between personal and business assets.
  5. 5

    Obtain an Employer Identification Number (EIN)

    Apply for a federal EIN through the IRS website, even if you don't plan to hire employees. This free process typically takes a few minutes online and provides the tax ID number most banks ask for when you open a business account.

    Pro tip: Get your EIN immediately after filing your Articles of Organization to avoid delays in opening business accounts.
  6. 6

    Open a Business Bank Account

    Separate your business and personal finances by opening a dedicated LLC bank account. Bring your Articles of Organization, EIN confirmation, and operating agreement to the bank. Most Montana banks offer business checking accounts with competitive rates.

    Pro tip: Shop around for business accounts with no monthly fees and convenient online banking features.
  7. 7

    Obtain Required Business Licenses

    Research and obtain necessary licenses and permits based on your business activities and location. Check requirements with Montana Department of Revenue for state licenses and your local city or county for municipal permits.

    Pro tip: Use Montana's Business Licensing Database to identify all licenses needed for your specific industry.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each Secretary of State publishes for forming an LLC, with the sources this page cites. It cannot tell you what your own filing needs: fees and forms change between our reviews, several occupations cannot use an ordinary LLC at all and must use a professional entity, and your city or county may require a registration of its own. Confirm the current fee and form with the filing office named on this page before you send anything.
