Ready to file your annual report?
Go directly to the Montana Secretary of State portal.
You must file Montana's Annual Report of Limited Liability Company (Form LLC-4) with the Montana Secretary of State by April 15 annually, using their online business services portal at sos.mt.gov. The filing fee is $25. Your report must include your LLC's legal name, Montana Organizational Number, registered agent name and street address (not a P.O. box), principal office address, and the name and mailing address of at least one member or manager. Missing the April 15 deadline results in automatic administrative dissolution—your LLC loses legal status and liability protection until reinstatement is filed with a $50 reinstatement fee. This means you cannot legally conduct business, enter contracts, or maintain corporate protection during dissolution. File immediately through the Secretary of State's online portal to avoid this costly consequence and maintain your LLC's good standing status.
If you miss Montana's April 15th annual report deadline, the Montana Secretary of State will assess a $5 late fee on top of the standard $15 annual report filing fee for a total of $20. You must file Form LLC-4 (Annual Report) through the Montana Secretary of State's Business Services Bureau to cure this violation. Critically, filing late doesn't immediately dissolve your LLC, but continued non-compliance triggers administrative dissolution proceedings. Montana provides written notice at your registered agent address and allows a 60-day cure period before formally dissolving your business. During dissolution, your LLC loses legal standing to conduct business, and creditors may pursue personal liability claims against members. To avoid this cascade of penalties and business interruption, file your annual report immediately if you've missed the deadline. Contact the Montana Secretary of State's office at (406) 444-2034 or visit sos.mt.gov to submit your delinquent Form LLC-4 today.
Yes, Montana law requires every LLC to maintain a registered agent with a physical Montana address for receiving legal documents and official state correspondence. You can serve as your own registered agent if you maintain a Montana office or residence where you're available during business hours to accept service of process. Alternatively, you can hire a professional registered agent service, which typically costs $100–$300 annually through providers like LegalZoom or local Montana firms. The registered agent's name and address must be listed on your Articles of Organization filed with the Montana Secretary of State and updated annually on your LLC's biennial report due by April 15th. This requirement has significant practical implications: failing to maintain a registered agent can result in administrative dissolution of your LLC by the Montana Department of State. If you choose self-representation, ensure someone is reliably present at your listed address; missing service of legal documents can lead to default judgments against your business. Contact the Montana Secretary of State's Business Services Bureau at (406) 444-2034 to verify your current registered agent information and confirm compliance before your next filing deadline.
Yes, Montana LLCs have minimal but essential ongoing compliance requirements beyond the annual report. Your annual report, filed with the Montana Secretary of State by April 15th using Form LLC-4, costs $25. Beyond this, you must maintain detailed business records, including meeting minutes and financial documentation, as Montana's Secretary of State may request them during compliance audits. Your registered agent information must remain current—notify the Secretary of State immediately if your agent changes using Form LLC-3. Montana imposes no franchise tax or publication requirements, unlike many states, significantly reducing your compliance burden. However, you must comply with industry-specific licenses; for example, real estate LLCs need broker licenses from the Montana Department of Labor & Industry, while professional service LLCs may require additional credentials. Failure to maintain accurate records or update agent information could jeopardize your liability protection. Your next step: review your registered agent details now and create a compliance calendar marking the April 15th filing deadline to prevent accidental administrative dissolution.
