Why do you need to do a business entity search?
To submit a Texas LLC application, you must choose a unique name that no other entity has registered with the Texas Secretary of State, including foreign businesses operating under a fictitious name.
If you don’t do a business entity search and file your LLC Certificate of Formation (Form 205) using a name already in use, the state could reject your LLC formation application, which has a $300 filing fee.
Then you’ll be back at square one, having to come up with a new business name and file again.
Texas state naming guidelines
Another reason the Texas Secretary of State might reject your name application is not complying with the Texas naming guidelines, which include:
- Mandatory inclusions: Your name must include the terms limited liability company or limited company or an abbreviation like LLC, L.L.C., LC, L.C. or Ltd. Co.
- Restricted words: Your name can’t suggest that your business is a government agency.
- Restricted or approval words: Some words need approval or are restricted by law. For example, names with “bank” or “trust” need approval from the banking regulator, and words like “college,” “university” or “Olympic” are restricted.
- Distinguishable: Your name must be distinguishable from other names on file with the Secretary of State, including reserved names (BOC §5.053). The rules for what counts as distinguishable are in 1 TAC ch. 79.
Conducting a business name search in Texas: Step-by-step guide with tips
You must file your LLC with the Texas Secretary of State, who lists all registered entity names and whether they are active or dissolved.
You check that list to ensure your chosen name is available in Texas by running a business name search.
Here’s how:
Perform a Texas entity search
You can conduct an online Texas business entity search in 2 ways:
- Use the Secretary of State’s SOSPortal to search business records. You need an account, and each search costs $1.
- Visit the Texas Comptroller website, which enables you to search for Texas taxable entities.
For our example, we’ll use the Texas Comptroller:
Texas Comptroller’s taxable entity search tool website
First, visit the Comptroller’s website, which will bring you to the page below, where you’ll see an entity name search box.
Type your chosen LLC name into that box (I’ll use Texas Car Wash as an example) and click search:

Reviewing the results
The taxable entity search results page shows any registered entities that match your search query along with the business name, Taxpayer ID number, and Zip code.

If you’re specifically checking LLC details, like whether a company is active, dissolved, or who its registered agent is, you can perform a Texas LLC lookup to access complete entity information directly from the Secretary of State’s records.
Next, click the entity name you’d like to review for further information, including the entity’s current status (active or inactive), mailing address, state of formation, Texas SOS file number (a number given to a registered entity by the Texas Secretary of State), and registered agent contact details.
The Comptrollers’ site shows the company’s current status as “whether it has the right to transact business in Texas.”

Pro tip:
You can call the Secretary of State at (512) 463-5555 to request their preliminary decision on your name’s availability. You can also email [email protected]. However, the SOS office can only make their final decision after processing your application.
DBA/assumed name
A DBA (Doing Business As), an assumed name in Texas, is a name other than your registered LLC name you can use to promote your business.
Texas doesn’t check assumed names for conflicts, so a quick Texas DBA name search helps you avoid a name another business already uses.
To register a DBA for an LLC, file Form 503 (Assumed Name Certificate) with the Secretary of State online through SOSPortal or by mail to P.O. Box 13697, Austin, TX 78711-3697. The fee is $25 (check or money order by mail).
What can you do once you have an available business name?
Now that you have an available Texas LLC name, you can check its online availability and ensure another company has not trademarked it.
You can also reserve your new LLC name in Texas to ensure no one else registers it.
Consider name reservation
You can reserve your new business name online through SOSPortal or by mail with the Application for Reservation of an Entity Name (Form 501). A reservation lasts 120 days, and you can renew it during the 30 days before it expires ($40).
Texas registration fees:
- Reserve a business name: $40.
- Form a Texas LLC: $300 (Certificate of Formation).
- File a DBA: $25.
Include all fees in your business financial plan to keep your LLC in Texas cost under control.
Consider trademarking your name
Once you confirm your name’s availability and reserve it, you can apply for a trademark to secure it nationwide.
To avoid trademark infringement, begin by running a name search using the federal trademark database to confirm another business (or person) hasn’t already “marked” your new LLC name.
Register your trademark with the United States Patent and Trademark Office, or with the Texas Secretary of State for protection in Texas only.
Consider domain registration
Most new businesses (including physical ones) need an online presence that often includes a Google Business Profile, social media platforms, and a website.
Here’s where choosing an LLC business name available as a domain and on your social platforms can help establish an effective branding strategy.
Confirm your name’s availability as a domain using a domain site like GoDaddy and perform a name search on your chosen social media platforms.
If your name isn’t available as a domain and unavailable on social media, consider changing it before registering your LLC with the Texas Secretary of State office.
Conclusion
Registering a name with the Texas Secretary of State is easy once you comply with the state’s naming requirements and confirm availability.
Remember, if you’re not ready to form your LLC, you can reserve your name online through SOSPortal for 120 days.
FAQ
Before forming your entity, ensure your chosen LLC name is available so the Texas Secretary of State will accept your application.
Use the Comptroller’s taxable entity search or the Secretary of State’s SOSPortal business search. You can also call the Secretary of State at (512) 463-5555 or email [email protected].
The name reservation filing fee is $40.
If your business uses a name other than its legal name, Texas requires an assumed name certificate. LLCs file with the Secretary of State. Until you file, you can’t bring a lawsuit over business done under that name, and intentional violations are a misdemeanor.
In Texas, your LLC name must include “limited liability company,” “limited company” or an abbreviation such as LLC, must be distinguishable from other names on file, can’t suggest a government connection, and may need approval if it uses regulated words such as “bank.”
You could register a DBA or choose a different LLC name that isn’t registered with the Texas Secretary of State’s office and is available as a trademark and a domain.
