Montana charges a $5 late fee for annual reports filed after the April 15 deadline each year. If your report remains unfiled 60 days past the deadline, the Montana Secretary of State will administratively dissolve your LLC without further notice. This dissolution immediately strips your business of liability protection, meaning you become personally responsible for company debts and legal judgments. Your business name also becomes available for others to use. To reinstate a dissolved LLC, you must file a Certificate of Reinstatement with the Montana Secretary of State and pay a reinstatement fee of $25, plus any outstanding annual report fees and late penalties. The reinstatement process typically takes 1–2 business days. To avoid this, file your annual report by April 15 through the Montana Secretary of State's online filing portal or by mail. Set a calendar reminder for early April to ensure timely filing.
You can file your Montana LLC annual report exclusively through the Montana Secretary of State website at sosmt.gov using their online filing system. Montana does not accept paper filings by mail for annual reports.
To file, log into your account on sosmt.gov, locate your LLC, and complete Form "Annual Report for Limited Liability Company." You'll need to update your principal business address, registered agent information, and list all current members or managers. The filing fee is $25, payable by credit or debit card during online submission.
Your annual report is due by April 15th each year. Filing online provides immediate confirmation and updates your LLC's good standing status instantly, which is critical since failure to file by the deadline results in administrative dissolution and loss of liability protection.
After submitting online, print your confirmation receipt and retain it with your business records for compliance documentation purposes.
Montana's LLC annual report filing fee is $15, payable to the Montana Secretary of State when you submit your report to the Business Services Bureau. You can pay online using a credit or debit card through the Secretary of State's filing portal, or by check or money order if filing by mail. If your annual report is not filed by the deadline (typically the last day of the month in which your LLC was formed), you'll face a $5 late penalty on top of the base fee, bringing the total to $20. This relatively low cost makes timely filing economical, but missing the deadline triggers the additional charge and could result in administrative dissolution of your LLC. To avoid penalties and maintain good standing, file your report through the Montana Secretary of State's online system at sos.mt.gov before your specific due date.
All Montana LLC annual reports are due by April 15 each year, regardless of your LLC's formation date. This fixed deadline applies uniformly to every LLC registered in Montana.
The Montana Secretary of State requires you to file Form LLC-4, the Annual Report for Limited Liability Company, by 5:00 p.m. Montana time on April 15. The filing fee is $25 when submitted by mail or $20 online through the Secretary of State's filing portal.
Missing this deadline carries serious consequences: your LLC's active status will be suspended 90 days after April 15, preventing you from conducting business legally in Montana. Once suspended, you'll need to file a reinstatement application with an additional $50 fee to restore your good standing.
To ensure compliance, submit your Form LLC-4 with updated member information and required details at least two weeks before the April 15 deadline. File online at sos.mt.gov for the lower fee and immediate confirmation of receipt.
No, there are no exemptions from filing annual reports for Montana LLCs. All active LLCs must file an annual report by April 15 each year with the Montana Secretary of State to maintain good standing with the state, regardless of business activity level or revenue. The annual report filing fee is $25, due alongside Form LLC-4 (the official Montana Annual Report form). Even LLCs with minimal or zero revenue, inactive operations, or single-member structures must comply. Failure to file by the deadline results in administrative dissolution, which removes your LLC's legal status and liability protection—making you personally liable for business debts. Reinstatement requires additional fees and paperwork. To stay compliant, mark April 15 on your calendar now and submit Form LLC-4 with the $25 fee to the Montana Secretary of State online at sos.mt.gov or by mail.
