General Rules for LLC Names

These rules typically apply to all LLCs, regardless of what state they’re formed in.

Your LLC Name Must Be Unique

Your preferred business name cannot be used by any other LLC or formed entity in the State of Montana. This is why it's imperative to perform a Montana business entity search before you begin the filing process.

Your LLC Name Must Not Be Confusable with Another Business Name

Your LLC name should be original, but that’s not enough. It also cannot be similar to the name of a corporation or LLC in Montana. For example, you cannot use the following factors to say your name is different and distinguishable from the name of another business:

  • Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., Ltd., LLC, etc.
  • Definite articles, such as “A,” “An,” or “The”
  • The conjunction "And," or “&"
  • The singular, plural or possessive forms of words
  • Abbreviations, punctuation, symbols, fonts, typefaces, etc.
Your LLC Name Must Contain Certain Words

All LLCs must have the words “Limited Liability Company,” “L.L.C.” or “LLC” in their names, normally at the end of the name.

Your LLC Name Must Have Other General Restrictions

Most states will not allow you to form LLCs with names that:

  • Are very similar to the name of a federal or state agency or organization (e.g., FBI, FDA, Montana Comptroller, Montana Police, Treasury, etc.)
  • Suggest affiliation with a federal or state agency or organization
  • Use the term “Olympic” or any terms that are trademarks of the International Olympic Committee
  • Imply a purpose that would be illegal for your business to carry out

Specific Rules for Montana Business Names

As mentioned above, Montana requires LLCs to comply with the general naming rules. Unlike many other states, the state of Montana doesn't require further naming regulations to be met.

Trademarks and Service Marks

You must be careful that your Montana LLC name doesn’t infringe on the trademark or service mark of another business. The easiest way to make sure your proposed business name doesn’t do that is to complete a trademark search through Incfile. If no one else is using it, you can even register it as a trademark yourself.

Make sure your business is starting off on the right foot when it comes to intellectual property.

Montana DBA or Assumed Name

You may do business under a different name from your legal LLC name. In some states, this is called a DBA (doing business as), trade name or fictitious name. In Montana, it's referred to as an assumed name. You may decide to use a Montana assumed name for a variety of reasons.

For example, your business might be called Western Adventures, LLC, and under that company, you have a chain called Rocky Mountain Trails. You could file for an assumed name just for that company. You'll need to submit a Registration of Assumed Business Name to do business under an assumed or fictitious name with the Montana Secretary of State. Or you can have Incfile do it on your behalf through our DBA service.

Note: A trade name is not the same as a trademark. Learn more about trademark vs. DBA.

Register Your Business Name with the Montana Secretary of State (SOS)

Once you’ve completed a Montana business entity search, checked availability, followed the naming rules and decided whether you need a trade name, you can register your LLC name. There are a couple of ways to do this.


If you don’t want to form your LLC right now, you can reserve the business name. You can file a form for a Reservation of Name with the Montana Secretary of State. Your name will be reserved for 120 days once the application is processed, and may not be renewed. If you’re forming your Montana LLC right away, you won’t need to reserve a name.


If you’re ready to start your LLC now, you can file your Articles of Organization with the Montana Secretary of State or have Incfile do it for you.

Incfile can handle all your formation paperwork with the State of Montana for you — and we’ll do it for free!
