What Montana LLC Costs Really Mean for Small Business Owners
Montana charges a $35 filing fee to form an LLC and charges $20 annually for the Annual Report. Including a registered agent ($125/yr), the total first-year cost is $180. Across all 50 states plus DC, LLC formation costs range from roughly $50 (Kentucky, Arkansas, New Mexico) to over $800 (Massachusetts, California with its $800 franchise tax) — a 16x gap. Montana ranks #6 of 51 states on total first-year cost, which is 53% below the national average of $381.
According to Census Bureau Business Formation Statistics, Americans filed over 5.5 million business applications in 2024, with LLC filings accounting for the majority of new formal business entities. The LLC structure is popular because it provides limited liability protection like a corporation while allowing pass-through taxation (profits flow to the owner's personal return via Schedule C, K-1, or 1040), avoiding the double taxation of C-corps. IRS Statistics of Income data shows LLCs represent roughly 70% of new business entity formations nationally. Montana offers online filing through the Secretary of State, which typically processes faster than paper submissions. Standard processing in Montana runs 5-7 business days, with expedited service available for an additional $20 reducing this to Same business day.
Budget beyond the state's direct fees. Most small business owners also spend $500–$2,000 in year one on general liability insurance, $50–$500 on business licenses and permits (varies by city and industry), and optionally $0–$500 on operating agreement templates or attorney review. Federal EIN applications are free through the IRS. If you plan to hire employees, add state unemployment tax registration and workers' compensation insurance. The total "all-in" cost to launch a functional LLC in Montana — fees, insurance, licensing, and basic setup — typically lands between $680 and $2,680 in year one, depending on industry and coverage choices.
