Montana LLC Annual Report: Filing Guide, Fees & Deadlines (2026)

Montana LLCs must file an annual report each year by April 15 to maintain good standing with the Secretary of State. The good news for business owners is that Montana has waived the annual report fee for reports filed between January 1 and April 15, in 2026 and again in 2027, making on-time compliance completely free.

What Is the Montana LLC Annual Report?

The Montana LLC annual report is a mandatory filing that all limited liability companies must submit to the Montana Secretary of State each year. This document serves as an official update to the state about your LLC’s current information, including its principal office address, registered agent details, and member or manager information. The requirement stems from Montana Code Annotated Title 35, Chapter 8, which governs limited liability companies in the state.

Every Montana LLC, regardless of size or business activity, must file this report annually to remain in good standing. This includes single-member LLCs, multi-member LLCs, domestic LLCs formed in Montana, and foreign LLCs authorized to do business in the state. The annual report ensures that the state maintains accurate records of all active businesses and provides a way for the public to access current information about your company.

Unlike some states that require biennial reports or have different requirements based on business type, Montana keeps it simple with a uniform annual filing requirement for all LLCs. The report itself is straightforward and can typically be completed in just a few minutes online through the Secretary of State’s business portal.

When Is the Montana LLC Annual Report Due?

Montana LLCs must file their annual report by April 15 each year, making it one of the earliest annual report deadlines in the United States. This deadline applies to all LLCs, regardless of when they were formed or registered to do business in Montana. The April 15 deadline coincides with the federal tax filing deadline, which can help business owners remember both important dates.

For newly formed LLCs, the first annual report is due by April 15 of the year following formation. For example, if you form your LLC on June 1, 2025, your first annual report would be due April 15, 2026. If you form your LLC on December 31, 2025, that same April 15, 2026 deadline still applies, giving you just over three months to file your first report.

The Montana Secretary of State typically sends reminder notices to the registered agent’s address approximately 30 days before the deadline. However, receiving or not receiving this notice doesn’t change your filing obligation. It’s the LLC’s responsibility to file on time regardless of whether a reminder is received. Many business owners set calendar reminders or work with registered agent services that handle annual report filings to ensure they don’t miss this crucial deadline.

How Much Does the Montana LLC Annual Report Cost?

Currently, there is no fee to file the Montana LLC annual report on time. The Secretary of State waives the fee for all annual reports filed between January 1 and April 15, a waiver announced for 2026 and again for 2027, as part of efforts to support small businesses and reduce regulatory burdens. After April 15 the fee is $35. This $0 filing fee applies to both online and paper filings, making Montana one of the most affordable states for LLC compliance.

While filing on time is free, late filers pay a fee. If you miss the April 15 deadline, the annual report fee becomes $35 — the $20 base fee plus a $15 late fee — and that single charge applies no matter how long you wait. There is no monthly penalty that accumulates: one day late and five months late both cost the same $35. This fee must be paid along with your annual report filing to bring your LLC back into good standing.

If your LLC fails to file the annual report for an extended period, it may face administrative dissolution. Reinstating an involuntarily dissolved LLC costs $35, plus an additional $35 for each year of delinquent annual reports. Additionally, during the period of dissolution, another business could potentially claim your LLC’s name, and you may lose certain legal protections that come with active LLC status. One year of delinquency therefore costs $70 to put right and two years $105, making timely filing the most economical choice.

How to File Your Montana LLC Annual Report: Step-by-Step

Step 1: Gather Required Information

Before starting your annual report, collect all necessary information about your LLC. You’ll need your LLC’s exact legal name, Montana Secretary of State filing number, current principal office address, registered agent name and address, and information about members or managers. Having this information ready will make the filing process much quicker and help avoid errors that could delay processing.

Step 2: Access the Montana Business Portal

Visit the Montana Secretary of State website at sosmt.gov and navigate to the business services section. Look for the “File Annual Report” option or search for your business using the business entity search tool. You’ll need your LLC’s name or filing number to locate your business in the system. The online portal is available 24/7, making it convenient to file at any time before the deadline.

Step 3: Verify and Update LLC Information

Once you’ve accessed your LLC’s record, carefully review all pre-populated information. The system will display your current registered information, including your principal office address, registered agent details, and member/manager information. Update any information that has changed since your last filing or since formation. Common updates include address changes, registered agent changes, or updates to member/manager information.

Step 4: Complete the Annual Report Form

Fill out all required fields in the annual report form. The Montana annual report is relatively simple compared to other states, typically requiring confirmation or updates to basic business information. Make sure all addresses include complete street addresses (not just P.O. boxes for the principal office), and verify that your registered agent has consented to continue serving in that capacity. Double-check all information for accuracy before proceeding.

Step 5: Submit and Confirm Filing

Review your completed annual report one final time before submission. Since there’s no filing fee for a report filed by April 15, you can submit the report immediately without payment. After submission, you should receive a confirmation email or filing number. Save this confirmation for your records as proof of filing. The report is typically processed immediately for online filings, updating your LLC’s status to current.

Step 6: Update Your Records

After successfully filing your annual report, update your LLC’s internal records to reflect any changes made during the filing. Set a reminder for next year’s April 15 deadline, and consider establishing a compliance calendar that includes all important LLC dates and deadlines. If you made any significant changes, such as a new registered agent or principal address, notify relevant parties like your bank, vendors, or clients as appropriate.

What Happens If You Don’t File?

Failing to file your Montana LLC annual report by the April 15 deadline triggers a series of increasingly serious consequences. Initially, the report fee rises to a flat $35 for any report filed after April 15, and that amount does not grow the longer you wait. During this time, your LLC remains active but is not in good standing with the state, which can affect your ability to obtain certificates of good standing needed for loans, contracts, or business licenses.

If your LLC continues to neglect its annual report filing obligation, the Montana Secretary of State will eventually move to administratively dissolve the company. Montana law does set a specific timeframe: an LLC that has failed for 140 days to file its annual report within the time required by law may be dissolved involuntarily by order of the Secretary of State, who compiles the list of delinquent companies by September 1 each year. Before dissolution, the Secretary of State serves or publishes a notice, and the company is dissolved if the grounds are not corrected within 90 days of that notice.

Administrative dissolution has serious consequences for your business. A dissolved LLC loses its name protection, meaning another business could register using your company name. Members do not, however, become personally liable simply because the company lapsed: under Montana law the failure of an LLC to observe the usual company formalities is not a ground for imposing personal liability on its members or managers, and after dissolution a member is liable only to the company itself for loss caused by an action inappropriate to winding up, with the company’s assets held in trust for liquidation. Additionally, a dissolved LLC cannot legally conduct business in Montana, enter into contracts, or maintain lawsuits. To reinstate the LLC, you must file all missing annual reports and submit a reinstatement application with a $35 reinstatement fee plus an additional $35 for each year of delinquent annual reports. The entire process can be costly and time-consuming, making timely annual report filing essential for maintaining your LLC’s good standing.

Frequently Asked Questions

Can I file my Montana LLC annual report before the April 15 deadline?

Yes, Montana allows LLCs to file their annual reports early. The filing period typically opens in early January each year, giving you approximately three and a half months to complete your filing before the deadline. Filing early is recommended as it ensures you won’t forget or miss the deadline due to unexpected circumstances. Many business owners make it a practice to file in January or February as part of their start-of-year business tasks.

Do I need to file an annual report if my Montana LLC had no business activity?

Yes, all Montana LLCs must file an annual report regardless of business activity level. Even if your LLC had no revenue, conducted no business, or remained completely dormant throughout the year, you’re still required to file the annual report by April 15. The annual report requirement is based on the LLC’s existence as a legal entity, not its business activity. If you no longer want to maintain the LLC, you should formally dissolve it rather than simply stop filing annual reports.

What’s the difference between the Montana annual report and tax returns?

The Montana LLC annual report and tax returns are completely separate filings with different purposes and agencies. The annual report is filed with the Montana Secretary of State and updates your LLC’s basic information like addresses and registered agent details. It’s a compliance requirement that maintains your LLC’s legal standing. Tax returns, on the other hand, are filed with the Montana Department of Revenue and the IRS, reporting your LLC’s income, expenses, and tax obligations. You must file both to remain compliant, and completing one doesn’t satisfy the requirement for the other.

Can I change my registered agent when filing the annual report?

Yes, you can update your registered agent information when filing your annual report. This is actually one of the most common changes made during annual report filings. If you’re changing your registered agent, make sure the new agent has agreed to serve in this capacity before making the change. In Montana, the registered agent must have a street address in the state (not just a P.O. box) and be available during normal business hours to receive legal documents. You should also notify your previous registered agent that they’re being replaced.

How do I know if my Montana LLC annual report was successfully filed?

After filing your annual report online, you should receive immediate confirmation on screen and via email if you provided an email address. This confirmation typically includes a filing number and timestamp. You can also verify your filing by searching for your LLC on the Montana Secretary of State’s business entity search portal, where the filing status should show as “Active” and “In Good Standing” once the report is processed. Keep your confirmation for your records, as it serves as proof of timely filing should any questions arise.

Bottom Line

Filing your Montana LLC annual report is a simple but crucial requirement for maintaining your company’s good standing. With no filing fee for a report filed by April 15 and a straightforward online process, there’s no reason to miss the April 15 deadline and risk the $35 late filing fee or administrative dissolution. The few minutes it takes to complete this annual filing protects your LLC’s legal status, name rights, and limited liability protection.

Set a recurring reminder for early March each year to complete your annual report filing well before the deadline. Consider filing as soon as the window opens in January to avoid any last-minute issues. By staying on top of this basic compliance requirement, you ensure your Montana LLC remains in good standing and can continue operating without interruption. Remember, while filing by April 15 is free now, a report filed after that date costs $35, making timely filing both legally necessary and financially smart.
