How to File

  1. 1

    Choose Your New Registered Agent

    Select an individual who is a Montana resident or a business entity authorized to conduct business in Montana. Your new agent must have a physical Montana address (not a P.O. Box) and be available during normal business hours to receive legal documents.

  2. 2

    Obtain Written Consent

    Get written consent from your new registered agent before filing. This ensures they understand their responsibilities and agree to serve as your agent. Keep this consent in your LLC records for future reference.

  3. 3

    Complete the Statement of Change Form

    File a Statement of Change of Registered Agent and/or Registered Office online through the Montana Secretary of State website at sosmt.gov or submit a paper form. Include your LLC's name, current agent information, and new agent details.

  4. 4

    Pay the Filing Fee

    Submit the required $15 filing fee. Online filings can be paid by credit card, while paper filings require a check or money order made payable to the Montana Secretary of State.

  5. 5

    Update Your Records

    Once the change is processed, update your internal LLC records and notify banks, vendors, and other business contacts of your new registered agent information. The change typically becomes effective immediately upon filing.
