What A Montana LLC Is (and Why People Form One)
A LLC entity is the small-business entity that combines liability protection for the owner with simple tax treatment by default. Across Montana's business community, the LLC dominates as the small-business entity of choice for its protection-plus-simplicity package.
The $35 Montana LLC Filing Fee (and the Other Numbers)
| Item | Cost |
|---|---|
| Our LLC formation service | $199 one-time |
| State filing fee (Montana Secretary of State) | $35 one-time |
| Registered agent (required for every Montana LLC) | $99/year |
| State annual report fee | $20/year |
$199 is our filing service. The state fee is collected by Montana Secretary of State. Registered agent plan is a separate $99 per year line.
Montana notes worth knowing: the official Montana filing fee is $35, which makes this one of the cheapest states in the country to form an LLC. Forming a series LLC? The state's fee page lists that filing at $35 plus $50 for each series member named. After formation, the annual report is $20 a year, due by April 15, and a $15 late fee brings a late filing to $35 total.
The Articles of Organization (Montana's Formation Document)
The document that creates a Montana LLC is the Articles of Organization. The authority is Mont. Code Ann. § 35-8-201, which provides that "one or more persons may form a limited liability company consisting of one or more members by signing and filing articles of organization with the secretary of state."
There is no form number to look up. Montana's business filings are online only, so the Articles of Organization are completed and submitted inside the Secretary of State's Business Filing Portal rather than on a numbered paper form. There is no mail-in option.
The Steps to Form a Montana LLC
- Name your Montana LLC. The name must signal its entity type with an approved designator and must be distinguishable from every name already on the state's records. Run candidates through the Secretary of State's business search before you commit. Words that suggest a bank, an insurer, or a government body are restricted without the underlying licensure.
- Appoint your Montana registered agent. Every Montana LLC keeps an agent with a real street address in the state, and the agent's address becomes part of the public record. Our agent product in Montana is $99 a year; you list us on the filing and your own address never enters the public database.
- File the Articles of Organization online. Create or sign in to an ePass Montana account at biz.sosmt.gov and submit the articles: entity name, principal address, registered agent details, management structure (member-run or manager-run), and your organizers. Pay the $35 state fee at submission. Since the state retired paper filings, the portal is the only channel.
- Create your operating agreement. Montana never asks you to file one, but the agreement fixes ownership, profit allocation, decision rights, and member changes in writing. Skip it and Montana's statutory defaults govern the company by operation of law, whether or not they match your intentions.
- Get an EIN from the IRS. The federal tax ID for the LLC, needed for banking, payroll, and returns. Apply free at IRS.gov; the online application takes about ten minutes and issues the number immediately. Never pay a third party for this.
- Stay compliant after formation. Keep a registered agent with a Montana street address on file at all times, file the $20 annual report between January 1 and April 15 each year, keep business and personal finances strictly separated, and meet federal and state tax deadlines. Fall out of compliance and the Secretary of State can administratively dissolve the LLC, taking the liability shield with it until you reinstate.

Why the Registered Agent Rule Matters
All Montana LLCs must maintain a registered agent, and it's a statutory obligation rather than a recommendation. The agent's job is to:
- Keep an actual Montana location with a street address (a PO box alone won't satisfy the statute)
- Be reachable all through normal business hours to receive legal mail
- Pass along incoming state correspondence and legal documents fast enough to preserve the LLC's response time
Owners often use their home address as agent and later wish they hadn't. Process servers, marketers, and any curious party can pull it up at will.
$99/year buys you our agent plan. We handle the public side of the agent role for you.
