Montana LLC Cost FAQ

To form an LLC in Montana, you need to file the Articles of Organization with the Secretary of State. This can be done online and comes with a filing cost of $35. The Articles of Organization is a foundational document that includes information about your LLC such as its name, purpose, and the name and address of its registered agent.

Your Montana LLC's registered agent can be an individual resident of Montana or a business entity authorized to do business in Montana. The role of the registered agent is to accept legal papers and other official documents on behalf of your LLC.

In Montana, you can verify the availability of your desired LLC name through the Business Search on the Secretary of State's website. This is important to ensure your chosen name is not already in use by another business entity in the state.

In Montana, an “assumed business name” is the state’s term for a “doing business as” (DBA) name. This allows your LLC to operate under a name other than its legal name. Remember, to use an assumed business name, it must be registered with the state.

Every year, Montana LLCs must file an annual report with the Secretary of State. The fee for this is $20 if filed prior to April 15, and $35 if filed after April 15. The annual report helps the state maintain updated records about your business.
