Whether you’re searching for the right Texas business name or registering your LLC with the TX Secretary of State, we can help. We’ve got all the information you need on Texas business entity searches, LLC naming rules, fictitious names and registering your business.

General Rules for LLC Names

These rules typically apply to all LLCs, no matter what state they are formed in.

Your LLC Business Name Must Be Unique

The business name you have chosen cannot be used by any other LLC or corporation in the state of Texas. This is why you should check business name availability on the TX SOS website.

Your LLC Business Name Must Not Be Confusable with Another Business Name

It’s not enough for your TX LLC name to be unique. It also cannot be similar to the name of a corporation or LLC in Texas. For example, you cannot use the following factors to say your name is different from the name of another business:

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

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

Your LLC Business Name May 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 TX agency or organization (e.g., FBI, FDA, Texas Comptroller, Texas 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 Olympic organization
  • Imply a purpose that it would be illegal for your business to carry out

Specific Texas Rules for Business Names

In addition to the general rules listed above, the Texas Secretary of State has some specific business naming rules for your LLC. You will need to follow these rules if you want to name your TX business appropriately. Here are some direct quotes from the Texas Secretary of State:


Where prohibited by §31.005 and §181.004 of the Texas Finance Code, an entity name cannot include the words "bank," "bank and trust," "trust," "trust company" or a similar term, phrase or foreign language word unless accompanied by a no objection letter from the Banking Commissioner


Where prohibited by §61.313 of the Texas Education Code, an entity name cannot include the words "College," "University," "School of Medicine," "Medical School," "Health Science Center," "School of Law," "Law Center," or "Law School," whether in English or in another language, unless accompanied by a no objection letter from the Texas Higher Education Coordinating Board


Where prohibited by §5.062 of the Texas Business Organizations Code, an entity name cannot include the words "Veteran," "Legion," "Foreign," "Spanish," "Disabled," "War," or "World War" if the name implies the entity is created for the benefit of war veterans and their families, without written approval issued from a veterans organization pursuant to §5.062 of the Texas Business Organizations Code.


The words "insurance" or "surety" must be accompanied by other words that remove the implication that the entity purpose is to be an insurer

Texas Business Entity Searches

Once you have an idea what business name you’d like to use, you’ll need to complete a “Texas business entity search.” Incfile offers a fast, simple and convenient tool to look up your proposed business name. The Texas Comptroller also has a tool that lets you search the register of TX LLCs and corporations to see if someone already has your desired business name.

The Texas Secretary of State search tool lets you enter details and search for your TX LLC by the following fields:

  • Tax ID
  • Entity Name
  • File Number

If the business name is already used, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

DBA / Assumed Names for Texas LLCs

You might choose to do business under a different name from your legal LLC name. In Texas, doing business under a different name is known as an “Assumed Name.” You might choose to use a different name from your TX formal LLC name for a variety of reasons.

For example, your LLC might be called Texas Alternative Power Holding Company LLC and you have a chain called Home Solar Energy Systems. You should file an assumed name to let the Texas Secretary of State know. In Texas, you do that through an “Assumed Name Certificate” form or you can have Incfile do it on your behalf through our Assumed Business Name service.
