What Montana calls a DBA
The official term documented here is Assumed Business Name.
Montana calls this registration an Assumed Business Name. Its business-structures guide permits sole proprietors, partnerships, corporations and LLCs to use the route. A sole proprietor operating outside their own name must register; the general-partnership guidance says a partnership may register. Those are different statements, so this guide does not turn eligibility for every entity into a universal obligation.
If you plan to start a sole proprietorship and you are not planning to do business under your own name, you must Register an Assumed Business Name with the Secretary of State’s Office. Otherwise, no registration is required.
A general partnership may register with the Secretary of State by filing an Application for Registration of Assumed Business Name. The filing fee is $20. A partnership agreement is generally maintained by the partnership itself. However, if you choose, you may file a partnership agreement with the Secretary of State’s Office once the application for registration of assumed business name has been filed and there is a $20 filing fee to record the agreement. Partnership Agreements may also be uploaded as Supporting Documents when filing the initial application form.
An assumed business name can be used by: - a sole proprietor, - a corporation, - a partnership, - a limited partnership, - a limited liability company, - a limited liability partnership, or, - an association.

A general partnership may register with the Secretary of State by filing an Application for Registration of Assumed Business Name. The filing fee is $20. A partnership agreement is generally maintained by the partnership itself. However, if you choose, you may file a partnership agreement with the Secretary of State’s Office once the application for registration of assumed business name has been filed and there is a $20 filing fee to record the agreement. Partnership Agreements may also be uploaded as Supporting Documents when filing the initial application form.
Renewal, amendment, and abandonment
Montana’s registration instructions say an assumed business name must be renewed every five years. The renewal help distinguishes ABN renewals from LLC and corporation annual reports, even though they share the same portal. Renew the name before its expiration.
Annual reports (LLC, Corporations) and Renewals (Assumed Business Names, Partnerships) are filed via the same portal. To maintain good standing, submit your annual report before the deadline or renew your business before the expiration at biz.sosmt.gov/search/business.
The fee sheet lists $20 for renewal, $20 for an amendment to registration, and no fee for cancellation. The cancellation help directs the filer to their record’s Filing Actions, then Cancel an Assumed Business Name, and explains the online submission and confirmation email.

To change business structures from an Assumed Business Name to a Limited Liability Company, file a conversion to an LLC if the applicant on the registration is a partnership or an association.

When an individual ABN owner wants to keep the name while becoming an LLC, the official conversion help says to cancel the ABN and then register the LLC. Its conversion option applies when the ABN applicant is a partnership or association. This is a specific structure-change distinction, not a claim that every name amendment creates an LLC.
