Starting an LLC in Montana follows the same eight-step arc as every state: pick a name the state will accept, appoint a registered agent, file the formation document with the $35 state fee, then build the compliance layer that keeps the entity alive. This guide covers the Montana-specific numbers and hands you the state's full resource set; the deeper national treatment of each step lives in the complete formation guide.
The Five Steps in Montana
Two universal warnings apply with full force in Montana. The state's name approval is not trademark clearance: run the USPTO check before you commit (see trademarking your name). And the EIN is free at the IRS, instantly, so never buy it from a lookalike site; the walkthrough is in the EIN guide.
What It Costs in Montana
The formation filing fee is $35, paid once to the state. The recurring obligation is the Annual Report, and the state currently waives its fee for reports filed by April 15, with $35 charged after that date. A commercial registered agent adds $100 to $300 per year if you choose one over serving yourself; File.Business charges $149 with the first year included in a Montana formation. Where Montana sits against all 50 states, and whether forming elsewhere could ever make sense (for most Montana businesses: no), is covered in the cost breakdown and the best-state analysis.
Form your LLC
If you would rather not do this yourself, we prepare the articles, check name availability with the state, and file it for you. Or keep reading and file it on your own. This guide covers everything you need either way.
Where the Filing Goes, and What Montana Charges for Everything Else
Formation documents go to the Montana Secretary of State, Business Services division, through the state's filing system at biz.sosmt.gov. The document is the Articles of Organization and the state fee is $35. Standard review runs 5 to 7 business days; $20 moves the file to 24 hour processing. Before committing to a name, check it against the register through the Montana entity search.
What sets Montana apart is the price of everything that comes after formation. A Certificate of Existence costs $5, which is close to the lowest in the country, and Montana treats it as current for 90 days rather than the 60 that most states allow. That extra month is genuinely useful when a lender's underwriting drags on. The certificate also reports the entity's annual report compliance status, so it doubles as a self-audit: order one for $5 and you can see what a counterparty would see. The Montana certificate guide covers ordering and apostille.
Changes are priced in the same register. Articles of Amendment to alter the name or purpose cost $15. Articles of Dissolution to close the entity properly cost $15. A Statement of Change of Registered Agent under Mont. Code § 35-7-103 costs $15. An Assumed Business Name, Montana's trade name registration, is $20 at state level with a five year renewal. A business can correct its name, its agent and its trading name for less than the cost of a single filing in Massachusetts.
The agent requirement itself is conventional: a Montana street address, staffed during normal business hours, with 30 days notice if the agent resigns. What is not conventional is how often the appointment is the weak link here, because Montana attracts owners who do not live in the state and therefore depend entirely on a commercial provider staying current. The Montana registered agent guide covers the choice.
After Approval: the Montana Checklist
The stamped formation document plus the EIN letter opens the business bank account, and running every business dollar through that account is what keeps the liability shield real (the solo-owner version of this warning is in the single-member guide). Adopt the operating agreement the same week: the Montana operating agreement guide covers the state specifics. Then calendar the recurring obligations: start with the Montana annual report guide, or put the entity on compliance monitoring and let the calendar watch itself.

Montana vs the Famous Formation States
Founders operating in Montana regularly ask whether Wyoming or Delaware would be cheaper. The arithmetic answers it: an out-of-state LLC that operates in Montana must still register in Montana as a foreign LLC, pay Montana's fees, and maintain a second registered agent, so the famous state becomes a surcharge, not a substitute. The five-year comparison for a business that lives here:
| Structure | Formation cost | Recurring | Five-year state cost |
|---|---|---|---|
| Montana (home state) | $35 | Report fee waived | $35 while the waiver holds |
| Wyoming + Montana foreign registration | $100 + Montana filing | Two states, two agents | $400 + all Montana costs anyway |
| Delaware + Montana foreign registration | $110 + Montana filing | $300/yr DE tax + Montana costs | $1610 + all Montana costs anyway |
The genuine exceptions (venture-backed startups, non-US founders, pure holding companies) are mapped honestly in the best-state analysis. For a business operating in Montana, forming in Montana wins on cost, simplicity, and risk surface.
Five Montana Mistakes That Undo a Cheap Filing
Mistake 01: Pricing the state by its fees and forgetting its deadlines
Why it happensA $35 formation and an annual report with no fee read as a state that does not take any of this seriously.
ConsequenceMontana dissolves administratively at about 24 months delinquent, exactly like states charging ten times as much. The cheap fee bought the same obligation, not a lighter one.
PreventionPut April 15 in the calendar at formation and file in March. Deadlines by state shows how the date compares.
Mistake 02: Depending on an agent nobody has spoken to in years
Why it happensMany Montana entities are owned by people who live elsewhere, so the registered agent is the only address the state can reach and the only party watching for notices.
ConsequenceA lapsed or unresponsive agent means dissolution notices and service of process go unanswered, and the first news of a problem arrives from a bank rather than the state.
PreventionConfirm the agent appointment annually, and file the $15 Statement of Change of Registered Agent as soon as anything moves.
Mistake 03: Never ordering the $5 certificate
Why it happensCertificates are usually bought only when a third party demands one.
ConsequenceBecause the Montana certificate prints annual report compliance status, owners lose the cheapest self-audit available anywhere: $5 shows exactly what a lender will see, before the lender sees it.
PreventionOrder one after each annual report is filed and keep it on file; it stays current for 90 days.
Mistake 04: Forming here while operating somewhere else
Why it happensMontana's fee schedule is genuinely the lowest around, and that is a powerful argument in isolation.
ConsequenceA business that actually operates in another state has to register there as a foreign entity anyway, so it pays that state's fees plus Montana's report, plus two registered agents, forever.
PreventionForm where the business operates unless there is a specific, documented reason not to. The best-state analysis maps the genuine exceptions.
Mistake 05: Relying on Mont. Code § 35-8 to sort out the money
Why it happensMontana does not require an operating agreement, so a two-person company often starts on a handshake.
ConsequenceThe statute supplies member-managed operation, per-capita voting and capital-weighted distributions. Voting power and profit share therefore follow two different rules, which is a dispute waiting for a reason.
PreventionAdopt an agreement that states both, and document capital as it goes in. The Montana operating agreement guide covers the drafting.
Montana in Practice: Three Businesses
Example 01: A fly-fishing guide in Bozeman
He files the Articles of Organization for $35 in February, takes standard processing, and has the approval in six business days. He registers an Assumed Business Name for $20 because the guiding brand differs from the entity name, and it runs for five years. The EIN is free and immediate, and the operating agreement is signed even though he is the only member, because charging-order protection is easier to argue with documentation than without.
His annual duty is the Annual Report by April 15, currently at no charge. He orders a $5 Certificate of Existence straight after filing it, both as proof for his outfitter licence and as a check that the compliance status line reads correctly.
Outcome: Under $80 in state fees for a fully documented first year, with proof of standing that costs less than a tank of fuel.
Example 02: Three partners in a Missoula brewing company
Two partners fund the build-out and the third runs operations. Under Mont. Code § 35-8 they would vote per capita while distributions tracked capital, so the operating agreement sets both explicitly and appoints the operating partner as manager. They file for $35 and add the $20 expedite to get 24 hour approval, because the equipment supplier will not schedule installation without an entity to invoice.
The lender financing the tanks asks for proof of standing and receives the $5 Certificate of Existence, valid for 90 days, which comfortably covers a slow underwriting cycle. When they later add a fourth partner and change the registered office, that is Articles of Amendment at $15 plus a $15 agent change, covered in the Montana amendment guide.
Outcome: Installation goes ahead on schedule and the partners' economics are documented before the first barrel is sold.
Example 03: A Colorado consultancy holding a Montana property entity
The owners live in Colorado, run their consultancy there, and hold a Montana rental property in a separate Montana LLC. The consultancy stays registered in Colorado, where it operates. The Montana entity exists only to hold the property, so it is formed here for $35 with a commercial registered agent supplying the in-state address the owners cannot.
Their exposure is the one they cannot see: every state notice goes to the agent, not to them. So they file the Annual Report each April, order a $5 certificate afterwards to confirm the compliance line, and diarise an annual check that the agent appointment is still live. Had they instead tried to run the consultancy itself through the Montana entity while working from Colorado, they would have needed a foreign registration in Colorado as well, paying twice for one business. The Montana foreign qualification guide covers registrations in the other direction.
Outcome: A holding entity that stays in good standing because its owners treat the agent relationship as an annual checkpoint rather than a one-time purchase.
The Real Risk in a Cheap State
Montana's recurring obligation is an Annual Report, due April 15, and the state currently waives the fee for an LLC that files by that date. The fee after April 15 is $35. Those are the smallest numbers in this guide, and that is the problem: a filing that costs nothing on time and $35 late does not feel like something a business can be destroyed by, so it slides down the list until the entity is no longer there.
| Years behind | Late report fee per year | Total owed |
|---|---|---|
| One | $35 | $35 |
| Two | $35 | $70 |
| Three | $35 | $105 |
A hundred dollars of arrears is not what damages the business. Two things do. The first is visibility: because the $5 Certificate of Existence reports annual report compliance status, a delinquent Montana entity announces itself on the cheapest document in the state. Any bank, insurer or contracting officer who spends $5 sees the gap immediately, and there is no version of the certificate that omits it.
The second is administrative dissolution at roughly 24 months delinquent. From that point the liability separation the LLC was formed to create stops doing its work, the name is no longer held, and any business conducted in the meantime sits on a company the register says does not exist. For an owner who lives out of state and relies on a commercial registered agent for every notice, this can happen without a single piece of post reaching a desk that anyone reads.
Montana is comparatively kind about recovery. The cure is an Application for Reinstatement, the window runs 60 months from dissolution, and Montana does not require a tax clearance certificate first, which removes the second-agency dependency that adds weeks in Mississippi, Missouri and Maryland. You still pay $35 for every missed report, and you still spend the intervening period unable to show a clean certificate. If the business has ended, $15 of Articles of Dissolution closes it properly. If it has not, one filing each April keeps everything above intact. The Montana reinstatement guide covers the filing, the annual report guide covers the deadline, and compliance monitoring covers the memory.
$35 and a clean checklist
A Montana LLC is one filing, one agent, and a short follow-through list: agreement, EIN, licenses, bank account, and the recurring calendar. Do the follow-through and the entity does its job.
Frequently asked questions
How much does it cost to start an LLC in Montana?
The Montana state filing fee for LLC formation is $35, paid once when the formation document is filed. Recurring state cost after that: the Annual Report, currently waived if it is filed by April 15 and $35 after that date. Add $100 to $300 per year if you use a commercial registered agent. Full numbers: the Montana cost breakdown.
Do I need a registered agent in Montana?
Yes. Every Montana LLC must continuously maintain a registered agent with a physical street address in the state, available during business hours to accept legal documents. You can serve yourself (your address becomes public record) or use a commercial service; the trade-offs are covered in our registered agent analysis.
Does Montana require an operating agreement?
State law does not require one, but every LLC should adopt one: banks ask for it, it fixes ownership and exit rules, and it is your primary evidence of entity separateness. See the Montana operating agreement guide.
How long does it take to get an LLC in Montana?
Online filings in most states are approved within one to five business days, and Montana publishes current processing times on its filing portal; check them before filing if you are on a deadline. The full stage-by-stage timeline, including the instant EIN and bank onboarding, is in our timeline guide.
Is it cheaper to form in Wyoming instead of Montana?
Not if the business operates in Montana: an out-of-state LLC must register here as a foreign LLC anyway, so Wyoming's $100 fee stacks on top of every Montana cost instead of replacing it, plus a second registered agent forever. The five-year math is in the comparison table above and the best-state analysis.
What happens if I ignore Montana's recurring requirements?
Montana's recurring obligations escalate the same way every state's do: late penalties first, loss of good standing next (which blocks loans and certificates), then administrative dissolution, which ends the liability shield. Reinstatement means back filings plus penalties. Compliance monitoring exists to make this failure mode impossible.
What taxes will my Montana LLC pay?
By default the LLC itself pays no federal income tax: profits pass through to your personal return with 15.3% self-employment tax on active income, plus state obligations. The full picture, including quarterly estimates and the S-corp election, is in the LLC tax guide and franchise tax by state.
Form your Montana LLC with the state fee at cost.
Name check against the Montana record, formation prepared and filed, operating agreement, EIN, and a year of registered agent service. The $35 state fee passes through with no markup.
