The real total depends on your registered agent choice, your residency status, and whatever add-ons a formation service bundles in. Some founders pay $35 and walk away. Others pay $400+ once agent fees, expedited processing, and compliance extras stack up.
This article breaks down the exact filing fee, the recurring costs, the fees people overlook, and how to budget correctly before you file.
Key Takeaways
- The $35 Montana state filing fee is fixed. No provider can waive it
- Annual maintenance ranges from $0 (self-agent) to $300+ (commercial agent plus extras)
- Non-residents almost always need a paid registered agent, which raises the true minimum cost
- No statewide sales tax gives Montana a cost edge over states like California
How Much Does It Cost to Form an LLC in Montana? (Pricing Overview)
The state-mandated Articles of Organization fee is $35 when filed online through the Montana Secretary of State's portal. That figure is the true "cost to form." Everything else is optional overhead layered on top.
Three mistakes trip up new founders constantly:
- Assuming a "free LLC" service eliminates the $35 state fee (it doesn't; the provider just waives its own markup)
- Forgetting that a registered agent isn't optional if you don't have a Montana street address
- Missing the annual report deadline and triggering a late fee plus dissolution risk
Here's how costs typically break down by filer type:
Basic Filer (Self-Agent, DIY)
Total: $35
State filing only. Best for Montana residents with a qualifying street address who can act as their own agent.
Standard Filer (Formation Service, No Agent)
Total: $35–$150
State filing plus EIN and an operating agreement template. Best for first-time founders who want guided filing without paying for an agent.
Nonresident/Full-Service Filer
Total: $150–$400+
State filing plus a commercial registered agent and compliance monitoring. Best for non-Montana residents or anyone who wants an added privacy layer.
Key Factors That Affect the Cost of a Montana LLC
Cost swings mainly come from four levers: who acts as your registered agent, how you file, whether you use a formation service, and which optional extras you add.
Registered Agent Choice
Self-agenting costs $0, but Montana requires a genuine physical address in the state, not a P.O. Box, plus availability during business hours. If you can't meet that bar, you'll need a commercial registered agent.
Commercial registered agent pricing varies widely:
- Montana Registered Agent LLC: around $45/year
- Harbor Compliance: $99 first year, $149/year renewal
- LegalZoom: up to $249/year
This is effectively mandatory for anyone without an in-state address, which includes almost every non-resident founder.
Filing Method and Processing Speed
Online filing runs $35. Need it faster? Montana offers expedited processing:
- 24-hour turnaround: +$20
- 1-hour turnaround: +$100
Formation Service vs DIY
DIY filing through the Secretary of State's portal costs only the state fee. Paid formation services usually run $79–$300+ and may bundle:
- EIN application
- Operating agreement template
- Registered agent service (on some packages)
Optional Add-Ons
- Name reservation: $10
- DBA/assumed name registration: $20
- Certified copies: $10
Cost Breakdown of a Montana LLC
Total cost has two layers: what you pay once to form the LLC, and what you pay every year to keep it in good standing.
| Item | One-Time or Recurring | Cost |
|---|---|---|
| Articles of Organization | One-time | $35 (mandatory state filing) |
| Registered agent | Recurring | $0 self-agent; $100–$300/year commercial |
| Annual report | Recurring | Often waived for on-time filers; $35 if filed after April 15 |
| Optional filings | Periodic | Name reservation, DBA, certified copies, as needed |
One detail catches people off guard: Montana's Secretary of State has waived the on-time annual report fee for recent filing years, but that waiver isn't guaranteed to repeat indefinitely. Always confirm the current-year status directly on the Montana Secretary of State's fee schedule before assuming it's free.
Montana vs Other States — Why Cost Comparisons Matter
Montana's $35 filing fee undercuts most of its regional neighbors:
- North Dakota: $135 to register an LLC, plus a $50 annual report
- South Dakota: $150 online for Articles of Organization, plus a $55 online annual report
Montana also has no general statewide sales tax, according to the Montana Department of Revenue. That cuts ongoing operating friction compared with states like California, which layer on sales tax, franchise tax, and higher minimum fees.
Forming in Montana only pays off if you actually live or operate there. If you're based elsewhere, you'll likely still need to foreign-qualify your LLC in your home state and pay that state's taxes and fees on top of Montana's. A cheap Montana filing fee doesn't cancel out obligations back home.
How to Estimate the Right Budget for Your Montana LLC
Budget around your residency status and long-term compliance needs, not just the lowest sticker price. Factors worth mapping out before you file:
- Self-agent eligibility versus a commercial registered agent if you lack a Montana address
- Whether you plan to hire employees, which triggers state withholding and unemployment insurance registration
- Local business license fees that vary by city and county (not on the state fee schedule)
- Cross-border tax exposure if you form from outside the US
That last point trips up a lot of international founders. A Montana LLC doesn't erase tax obligations in your home country—your domestic rules on foreign-earned income still apply.
VJM Global works with founders on this cross-border structuring, including treaty benefits, permanent-establishment risk, and double-taxation relief when both jurisdictions tax the same income.
What Most People Miss About Montana LLC Costs
A handful of assumptions cause the most expensive mistakes:
- Assuming "free LLC" eliminates the state fee. It never does. The $35 Articles of Organization fee is charged directly by the Secretary of State, not the formation company.
- Forgetting that non-residents can't serve as their own registered agent. Without a Montana street address, you're locked into a recurring $100–$300/year agent cost.
- Ignoring the annual report deadline. Miss the April 15 deadline and you owe a $35 fee. Repeated non-compliance risks administrative dissolution.
- Overlooking home-country tax obligations. Montana's tax simplicity applies only in Montana. It says nothing about what you owe your home state or country on income the LLC generates.
Conclusion
Forming a Montana LLC costs $35 at minimum. Realistic totals land anywhere from $35 to $400+, depending on your residency and which services you layer on. A quick recap of what drives the bill:
- State filing fee starts at $35
- Realistic all-in total: $35–$400+, based on residency and add-on services
- Registered agent rules and the annual report deadline are the items that trigger penalties if missed
Understanding the registered agent rule and the annual report deadline upfront saves you from penalties later.
Founders filing into Montana from outside the US often need help getting formation and compliance right on the first pass. VJM Global supports cross-border entity setup and ongoing US compliance so you are not fixing avoidable mistakes after the fact.
Frequently Asked Questions
How much does it cost to form an LLC in Montana?
The mandatory state filing fee is $35 online. This is the baseline cost no matter which formation service you use, since it's charged directly by the Secretary of State.
How much is a Montana LLC per year?
Budget for the annual report fee (often waived for on-time filers), plus $100–$300 per year if you hire a commercial registered agent instead of serving as your own agent.
What does it take to set up an LLC in Montana?
The core steps are a name search, appointing a registered agent, filing Articles of Organization, obtaining an EIN, and optionally drafting an operating agreement.
Is Montana a good state to form an LLC?
It's a strong choice for actual Montana residents due to low fees and no statewide sales tax. It's less beneficial for non-residents, who still owe taxes in their home state or country regardless of where the LLC is filed.
Can I avoid taxes with a Montana LLC?
No. Montana's lack of sales tax applies only to in-state transactions. Income earned elsewhere is still taxable in the owner's home jurisdiction.
