Montana requires every LLC to name a registered agent in the Articles of Organization it files to form. Hiring a paid service is optional: in most states the LLC's owner, or another individual who qualifies, may serve as its registered agent, and the rules below set out who qualifies in Montana. See the rules below.

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 phone, email and chat support
Our pick: ZenBusiness
A $0 Starter formation plan, backed by an A from the BBB and a 4.8/5 Trustpilot score. Registered agent is not included in any plan: it is $99 for the first year when you form with them, then $199/yr.
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 Northwest's report filing service, which charges your saved payment method $100 plus state fees each time it files for you and 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. 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 attorney consultations, which come with LegalZoom's $299 formation plan (and in one version of its plans its $249 plan) for 30 days and then cost $49 or $99 a month until you cancel, depending on the version. Also 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 missing a deadline can cost the company its good standing or, in many states, its existence.
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 Montana law requires. This agent accepts service of process, dissolution notices, and IRS communications during regular business hours. If your LLC goes 60 days without a registered agent, the Montana Secretary of State can administratively dissolve it, 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. To establish your registered agent, name it in your Articles of Organization; to update it later, file a statement of change of registered agent with the Montana Secretary of State. Set up this requirement during initial formation or immediately if your current agent is relocating out of state.
Montana may administratively dissolve an LLC that goes 60 days without a registered agent or without filing a change of registered agent.
Beyond dissolution, operating without a registered agent exposes your LLC to serious consequences: you risk a default judgment if you cannot receive legal documents, and lawsuits may proceed against you by default.
To reinstate within 5 years after the dissolution, file an application for reinstatement with the Secretary of State and pay the $35 fee, together with every annual report not yet filed and an additional $35 for each year of delinquent reports. A certificate that Montana taxes have been paid may also be required. After 5 years, the Secretary of State may not order reinstatement.
**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 a statement of change of registered agent immediately with the corrected agent details.
# Expanded Answer
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. A professional registered agent service charges its own annual fee, which varies by provider. Some online LLC formation services include the first year of registered agent service when you use them for initial LLC formation, though you'll pay the standard fee in subsequent years. Northwest Registered Agent includes a year of registered agent service inside its paid formation package ($39 plus your state's filing fee), and charges $125 per year for the agent service after that. A registered agent service is listed as the agent in place of you, so your home address does not have to appear in that entry. Other parts of a filing can still show an owner's name or address. 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 service they provide.
Only in part. When you hire a registered agent service, the service is listed as your registered agent in place of you, so your home address does not have to appear in that entry. That is the only part of your LLC's record a registered agent changes. Other parts of a filing can still show an owner's name or address. Assume that what you file with the state can be seen by the public, and read the blank forms your LLC files with the state filing office to see what each one asks you to list.
Yes, you can change your Montana registered agent at any time by filing a statement of change of registered agent with the Montana Secretary of State's Business Services Bureau; check the Secretary of State's fee sheet for the current fee. 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, and 60 days without an agent is a ground for administrative dissolution. File the statement online through the Secretary of State's website or by mail. Your next step is to confirm your new agent's acceptance before submitting the statement.
