Best Registered Agent Services for Montana LLCs (2026)
Affiliate disclosure: Northwest Registered Agent, Bizee, ZenBusiness and LegalZoom pay us a commission if you sign up through our link, at no extra cost to you. We list only the registered agent services we have an affiliate relationship with, so this is not a survey of the whole market.
This table is not scored. The four are listed cheapest annual renewal first, and the rows below it say which one fits which situation. The scored ranking, and the formula behind it, is on the formation services review, which orders them on three-year cost, BBB rating and Trustpilot score.
Note: Bizee holds a C rating from the BBB and is not accredited. BBB's profile carries a live alert describing a pattern of complaints about unexpected charges, difficulty canceling and filing delays, and Bizee has posted a response to it. We flag this so you can make an informed choice.
Prices are each provider's standard published rates; year-one pricing applies when you form your LLC through the same service. BBB and Trustpilot figures as recorded September 15, 2026, not re-checked since, and both sources update continuously. These are the dates the figures were last written to our dataset, which is the most we can show: they are not verification dates.

Which Registered Agent Is Best for Your Montana LLC?
You're forming a new LLC and want the agent bundled
Our pick: ZenBusiness
Registered agent is free for year one with their $0 starter formation plan, backed by an A from the BBB and a 4.8/5 Trustpilot score.
Your LLC already exists and you just need an agent
Our pick: Northwest Registered Agent
A flat $125/yr for registered agent service, the lowest renewal of the services listed here, and a privacy policy that says it does not sell your information. Registered agent customers are enrolled by default in annual report filing at $100 plus state fees, which you can cancel.
You want year one free and the cheaper renewal after it
Our pick: Bizee
Registered agent is free for year one on every Bizee plan and renews at $149/yr, $50/yr less than ZenBusiness, the other service listed here that includes year one free. Northwest renews lower still at $125/yr, but its first year comes inside a paid $39 formation package rather than free. Tradeoff: a C rating from the BBB, which cites a pattern of complaints about charges and cancellation, so read every auto-renewal term.
Complex legal needs alongside your filing
Our pick: LegalZoom
The only one of the services listed here with licensed attorney consultations, and the most expensive registered agent listed here at $249/yr, which is never included in their plans.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because the penalty for missing a deadline can be administrative dissolution of the company.
Frequently Asked Questions
A registered agent is a person or business designated by your Montana LLC to receive legal documents, tax notices, and official correspondence on behalf of your company. Montana law requires every LLC to maintain a registered agent with a physical street address (not a PO box) located in Montana, as mandated by the Montana Secretary of State under ARM 11.3.104. This agent accepts service of process, dissolution notices, and IRS communications during regular business hours. Without a registered agent, the Montana Secretary of State can administratively dissolve your LLC, and you may miss critical legal deadlines that could result in default judgments against your business. You can serve as your own registered agent if you maintain a Montana office, or hire a professional registered agent service (typically $75 to $200 annually). To establish or update your registered agent, file Form LLC-5 with the Montana Secretary of State at no additional fee beyond your standard filing costs. Set up this requirement during initial formation or immediately if your current agent is relocating out of state.
# Expanded Answer
Your Montana LLC faces automatic administrative dissolution if it lacks a registered agent. The Montana Secretary of State's office will issue a notice of intent to dissolve if your registered agent resigns or your agent's address becomes invalid, giving you 60 days to appoint a replacement before dissolution takes effect.
Beyond dissolution, operating without a registered agent exposes your LLC to serious consequences: you risk a default judgment if you cannot receive legal documents, lawsuits may proceed against you by default, and you forfeit the right to conduct business in Montana. The state can also assess penalties and back fees during the dissolution process.
Practically, this means missing a lawsuit, tax notice, or regulatory filing because your agent never received it, and having no legal defense. Your personal assets could become vulnerable if creditors pursue claims your LLC couldn't defend.
**Next step:** Verify your current registered agent's information on the Montana Secretary of State's business services portal (sos.mt.gov). If your agent has changed or the address is outdated, file an Amendment to Articles of Incorporation (Form LLC-5) immediately with the corrected agent details and contact information.

If you serve as your own registered agent in Montana, there's no additional cost beyond your standard LLC filing fees with the Montana Secretary of State. However, professional registered agent services in Montana typically charge $100 to $300 annually, with most reputable providers clustering around $150 to $200 per year. Some online LLC formation services, such as LegalZoom and Northwest Registered Agent, include the first year of registered agent services free when you use them for initial LLC formation, though you'll pay the standard fee in subsequent years. This cost difference has a significant practical implication: while self-serving saves money upfront, professional agents provide a business address for official documents, ensure compliance deadlines aren't missed, and maintain privacy by keeping your personal address off public records with the Montana Secretary of State. To determine the best option for your situation, compare quotes from at least three Montana-registered professional agents and calculate whether the annual fee justifies the liability protection and administrative relief they provide.
Yes, using a registered agent service in Montana substantially protects your privacy by keeping your personal address off public records filed with the Montana Secretary of State's Business Services Bureau. When you file your Articles of Organization (Form MCA 1-102) with the state, only your registered agent's business address appears in public filings and the searchable online business database. Your home or office address remains private. This prevents your personal information from appearing in competitor research, marketing lists, or public record searches. However, understand that this privacy protection applies only to state filings; the Montana Department of Revenue may still have your personal address for tax purposes, and creditors can potentially discover your identity through court records or business license applications. For maximum privacy, choose a professional registered agent service rather than listing an employee's address, since the agent's address becomes a permanent part of your public business record. To implement this protection immediately, file your Articles of Organization with a registered agent's address listed as your official address for service of process with the Montana Secretary of State.
Yes, you can change your Montana registered agent at any time by filing a Statement of Change of Registered Agent (Form LLC-5) with the Montana Secretary of State's Business Services Bureau. The current filing fee is $20, and processing typically takes 3 to 5 business days. You must ensure your new registered agent has a physical street address in Montana and is available during business hours to receive legal documents, as any gap in coverage could result in missed service of process and default judgments against your LLC. File the form online through the Secretary of State's website or mail it to Helena with the $20 fee. Update your registered agent immediately when changing agents to avoid service-of-process complications. Your next step is to confirm your new agent's acceptance before submitting the form to guarantee smooth legal protection for your business.
