How to File
- 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
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
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
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.

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.

This table is not scored. The four are listed cheapest annual renewal first, and the rows below it say which one fits which situation. The scored ranking, and the formula behind it, is on the formation services review, which orders them on three-year cost, BBB rating and Trustpilot score.
| Service | With formation, year 1 | Annual renewal | BBB | Trustpilot | Privacy |
|---|---|---|---|---|---|
| Northwest Registered Agent | Included with $39 formation | $125/yr | A | 4.1/5 (297) | Says it does not sell your information; runs its own servers |
| Bizee | Free year one | $149/yr | C (unaccredited) | 4.8/5 (26,100+) | No data-sharing commitment |
| ZenBusiness | $99, not included in any plan | $199/yr | A | 4.8/5 (32,500+) | Partial |
| LegalZoom | Not included, $249 extra | $249/yr | A+ | 4.6/5 (32,900+) | Partial |
Note: Bizee holds a C rating from the BBB and is not accredited. BBB's profile carries a live alert describing a pattern of complaints about unexpected charges, difficulty canceling and filing delays, and Bizee has posted a response to it. We flag this so you can make an informed choice.
Prices are each provider's standard published rates; year-one pricing applies when you form your LLC through the same service. BBB and Trustpilot figures as recorded September 15, 2026, not re-checked since, and both sources update continuously. These are the dates the figures were last written to our dataset, which is the most we can show: they are not verification dates.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because the penalty for missing a deadline can be administrative dissolution of the company.
