Find out what business type is right for you

If you want to start a Texas LLC or corporation (also referred to as “registering your business”), you'll need to file a “Certificate of Formation Limited Liability Company” for a Limited Liability Company or a “Certificate of Formation For-Profit Corporation” for a corporation. Those documents are filed with the Texas Secretary of State.

Before you file, you must choose a name for your LLC or corporation. This name will be the official legal name of your company.

It’s a good idea to check if your desired business name is available before submitting your formation documents.

Texas has rules on what you can name your LLC or corporation

Choosing a business name is an important decision. Your business name is often the first impression you make on prospects, customers, investors, partners, and employees.

If you choose a business name only to discover that it’s already in use when you try to register your business with the Texas Secretary of State, it can be frustrating and time-consuming.

As with other states, Texas has rules on what you can name an LLC or corporation.

In Texas, the name of an LLC or corporation must be distinguishable from the names of domestic and foreign filing entities that appear in the records of the Texas Secretary of State. Filing entities include corporations, LLCs, limited partnerships, and limited liability partnerships. The name must also be distinguishable from names that have been reserved or registered with the Secretary of State, fictitious names of foreign companies, and the names of registered series of Texas series LLCs.

Entity names are distinguishable and available if they are sufficiently different from an existing name and meet one or more of the following criteria:

  • At least one different word: For example, “Matthew’s Property Services” is distinguishable from “Matthews Property Development”. However, “Haven Community” would be considered the same as “The Haven Community”.
  • The same keywords, but in a different order: For example, “Cyber One” is distinguishable from “One Cyber”.
  • The keywords/contractions of keywords derive from the same word: For example, “New Age Products” is distinguishable from “New Age Productions”.
  • The keywords are the same but in a different language: For example, “Tejas Irrigation Services” is distinguishable from “Texas Irrigation Services.” However, “El Paso” would be considered the same as “Paso” or “The Paso”.
  • The key words sound the same, but at least one word has a different meaning or connotation: For example, “Knight Plumbing” is distinguishable from “Night Plumbing”. However, “Express Plumbing” would be considered the same as “Xpress Plumbing”.
  • The key words are similar except for changes in prepositions that sufficiently distinguish the names: For example, “Designs for Living” is distinguishable from “Designs by People”. However, “Path to Success” would be considered the same as “Path Toward Success”.

When checking whether a name is available, the Texas Secretary of State only considers names of companies already registered in Texas and in its records.

If you violate this rule or other naming rules, your LLC or corporation's Certificate of Formation may be rejected by the Texas Secretary of State’s office.

Trademark considerations for Texas business names

When selecting a name for your Texas business, name availability is just one consideration. You should also determine whether the name is trademarked. Filing a formation document with the Secretary of State to create a corporation or other entity only prevents the Secretary of State from accepting another filing with a name that is indistinguishable from yours—they do not check your proposed name against trademark registrations.

So, it’s important to familiarize yourself with federal and Texas state trademark laws. These protect businesses from using similar names, logos, or other marks that could cause customer confusion.

The consequences of trademark infringement are serious and include:

  • Receiving a cease-and-desist letter from the trademark owner.
  • Being subject to a civil lawsuit by the trademark owner without warning.
  • Held liable for the trademark owner’s financial losses and any profits you have made using their trademarked name.
  • Potential criminal charges, including counterfeiting charges.

About trademarking your Texas business name

While conducting a trademark search is recommended, registering your business name as a trademark isn’t required. However, if you use your business name to distinguish your products or services, it may function as a trademark. You can establish trademark rights through use alone, even without registering with the U.S. Patent and Trademark Office (USPTO).

That said, federal trademark registration offers stronger legal protection, including enhanced rights if another individual or business infringes on your mark.

In addition, Texas offers state-level trademark registration. This registration lets others in Texas know that you own the trademark for your goods or services in Texas commerce. However, registering your trademark with the Secretary of State does not guarantee that someone else doesn’t already have a stronger right to use that name in business.

When the Secretary of State reviews an application to register a trademark, they only look at their own database of registered Texas marks and the ones registered with the USPTO. They do not check state or county assumed name records, nor do they review the legal names of corporations or other entities.

They also do not search phone books, the internet, or any other common law uses of trademarks in commerce. It is the applicant's responsibility to conduct a thorough search to avoid infringing on someone else's trademark (more on this below). Private companies can provide a detailed search for a fee.

How to find out if a business name is taken

There's no one place to check for conflicting business names for your Texas LLC or corporation. Use different search methods to ensure you cover all bases.

1. Check the internet

Look up the name you are thinking about using on a search engine. This will help you determine whether others are using a similar name for comparable products or services. Additionally, check the availability of the website domain you're interested in by simply entering the name into the search bar and pressing enter. You can also use the ICANN WHOIS Lookup tool for this purpose. ICANN oversees all domain names.

 

2. Search the Texas Comptroller Business Entity Database

Companies that do business in Texas are generally required to register with the Texas Comptroller's office. You can search for existing business names using the Franchise Tax Account Status search page.

Be aware that broad search terms can lead to an overwhelming number of results. For instance, searching for "Texas" yields over 60,000 entries. You may need to use more specific terms to refine your results.

3. Search the Texas Secretary of State Business Entity Database

The main database for Texas business filings is SOSDirect, overseen by the Texas Secretary of State.

To access SOSDirect, you must create an account using a computer (smartphones and tablets are not supported).

Once your account request is processed, you will receive your User ID and password via email.

There is a fee of $1 for each search conducted on the platform.

Tip: If you're still coming up with name ideas, start with the free Franchise Tax Account Status search. This way, you can avoid paying unnecessary fees before using SOSDirect.

4. Perform a trademark search

Trademark conflicts may occur if you choose a business name that another party has a superior right to use in commerce.. To prevent this, check for registered trademarks through the United States Patent and Trademark Office (USPTO).

The USPTO has a free online trademark database where you can look for exact matches and similar names that might confuse customers.

When searching, check for common misspellings and variations of your name. Even if your name isn’t identical to someone else’s trademark, a similar name could still lead to challenges based on potential confusion.

You can check if a trademark has been registered in Texas. Note that federally registered trademarks must be used in interstate commerce. If a trademark is used only within Texas, it may be listed only in the state database. The Texas Secretary of State provides a trademark search tool that requires you to create an account to access.

5. Check for DBA filings

A person or business can operate under a name different from its legal name. This name is commonly referred to as a DBA, which stands for “doing business as.” A DBA can also be called an "assumed name," "trade name," or "fictitious business name." In Texas, this is called an assumed name.

In Texas, LLCs, corporations and other filing entities that operate under a name other their legal name must file an Assumed Name Certificate. The state does not reject DBA filings based on name conflicts. This means multiple businesses can legally use the same assumed name. However, it’s best not to pick a name already used by a competitor. Sharing a name with another local business can create confusion for customers or lead to legal issues.

Depending on the type of business, you file DBAs either at the state or county level:

  • LLCs, corporations, and other entities file with the Secretary of State (you can search this using SOSDirect).
  • Sole proprietors and general partnerships file at the county level.

Keep in mind that the Secretary of State does not check assumed name/DBAs against existing ones. Before choosing a name, search SOSDirect and contact the County Clerk in the area where your business will operate to see if the name is already taken.

6. Check social media handles

Check whether your preferred handle is available on major platforms, including Instagram, Facebook, TikTok, LinkedIn, X, and Bluesky. Also, consider business listing sites (like Yelp) to prevent any mix-ups with other businesses.

Tips on selecting a business name for your Texas LLC or corporation

Before choosing a business name, make sure it follows Texas’s naming rules.

  • Include the right words: The name of your LLC or corporation must include specific words or abbreviations that identify the type of entity you are forming. For instance, an LLC name must include "Limited Liability Company," "Limited Company," or an abbreviation of those phrases. A corporation’s name must include the word "company," "corporation," "incorporated," or "limited", or an abbreviation of one of those words. Also, in Texas, a name cannot include certain terms—such as "Bank," "Trust," "College," or "Health Science Center"—without obtaining prior authorization from the appropriate state board.
  • Check business name availability: Conduct a business entity search on the Comptroller and Secretary of State's websites to determine if there is already a corporation, LLC, or other entity registered with the proposed name. Be sure to check additional sources as well. This will help you avoid having your Certificate of Formation rejected.
  • Reserve your business name with the state of Texas: You can secure a "lock" on that name through the Texas Secretary of State by filing a name reservation. This prevents anyone from forming a domestic entity or registering as a foreign entity with a name that is indistinguishable from your chosen name, or reserving or registering an indistinguishable LLC or corporation name until you have filed your Certificate of Formation. In Texas, a business name reservation is valid for 120 days, and you can reserve an entity name as many times as you like.

Even if the name meets Texas’s rule, you may also want to do a trademark search to make sure the name wouldn’t infringe on someone’s trademark rights.
