Texas LLC Naming Rules & Requirements (2026)
Your Texas LLC name must follow specific statutory requirements to be accepted by the Secretary of State. These rules govern what designators you must use, which words are prohibited, and how to verify your name is available before filing. Understanding these requirements upfront prevents rejection and delays in forming your LLC.
Required LLC Name Designator
Your Texas LLC name must include one of three mandatory designators: Limited Liability Company, LLC, or L.L.C. (Tex. Bus. Org. Code § 5.053). This designator is non-negotiable and must appear in your official business name filed with the Secretary of State. It clearly identifies your entity as a limited liability company rather than a corporation, partnership, or sole proprietorship.
The designator can appear at the beginning, middle, or end of your company name. "Tech Solutions LLC," "LLC Tech Solutions," and "Tech LLC Solutions" all comply with Texas requirements. You cannot abbreviate or modify the designator—using "Limited" alone or "Company" without the full phrase will not satisfy the legal requirement.
The Secretary of State will reject your Articles of Organization if your proposed name lacks this required element. Include the exact designator when you file to avoid resubmission delays.
Name Distinguishability Standard
Your proposed LLC name must be distinguishable from any existing entity name already on file with the Texas Secretary of State (Tex. Bus. Org. Code § 5.053). This means you cannot register a name that is identical or confusingly similar to another business entity's registered name in Texas, regardless of the other entity's type or industry.
The Secretary of State applies a strict comparison standard. Names that differ only in punctuation, spacing, or the LLC designator itself may not pass the distinguishability test. If "Smith Consulting LLC" already exists, you cannot register "Smith Consulting, LLC" or "Smith Consulting L.L.C." The state treats these variations as non-distinguishable.
You should conduct a thorough name search before filing to avoid rejection and delays. The free search tool at https://www.sos.state.tx.us/corp/sosda/index.shtml lets you check availability instantly.
Restricted and Prohibited Words
Texas law prohibits certain words in LLC names without special authorization. Under Tex. Bus. Org. Code § 5.054, you cannot use the following words without meeting additional requirements:
- Bank
- Trust
- Insurance
- University
- College
If your business legitimately operates in one of these regulated industries, you may be able to use the restricted word, but you must obtain written consent from the appropriate state regulatory agency before filing. For example, if you want to use "Bank" in your name, you need approval from the Texas Department of Banking. Similarly, "Insurance" requires approval from the Texas Department of Insurance.
Using a restricted word without authorization will result in your LLC formation being rejected. The Secretary of State will not process your Articles of Organization until you either remove the restricted word or provide proof of regulatory approval.
How to Search for Available Names
Before filing your LLC, search the Texas Secretary of State's business database to verify your desired name is available. The official search tool is located at https://www.sos.state.tx.us/corp/sosda/index.shtml.
This online search allows you to check whether your proposed name—or similar variations—are already registered. You can search by entity name, file number, or registered agent. The search results show active entities, dissolved entities, and entities with pending status. Running this search takes only minutes and can save you from filing rejection and resubmission fees.
The search database is updated regularly but may have a slight lag. If you find your exact name is available, you should file your Articles of Organization promptly, as another business could register the same name while you are preparing your paperwork.
Name Reservation Process and Duration
If you want to secure your LLC name before filing your Articles of Organization, Texas allows you to reserve the name for 120 days. The name reservation fee is $40.00, payable to the Texas Secretary of State.
To reserve a name, you submit a reservation request through the Secretary of State's online filing system at https://www.sos.state.tx.us/corp/sosda/index.shtml. Once approved, no other business entity can register that exact name during the 120-day reservation period. This is particularly useful if you are still in the planning stages, negotiating with partners, or waiting for regulatory approvals before formally establishing your LLC.
The 120-day reservation period begins on the date the Secretary of State approves your reservation request. If you need the name reserved longer, you can file a renewal request before the initial period expires. However, you cannot renew a reservation more than once—after two 120-day periods (240 days total), you must file your Articles of Organization to maintain the name.
Doing Business As (DBA) Requirements
If you plan to operate your Texas LLC under a name different from your registered LLC name, you must file a Doing Business As (DBA) certificate, also called a trade name registration. This is a separate filing requirement from your LLC formation.
For LLCs, you file the DBA with the Texas Secretary of State using Form 503. The filing fee is $25.00. For example, if your LLC is legally named "Smith Holdings LLC" but you want to conduct business as "Smith's Coffee Shop," you must file a DBA for the trade name.
The DBA filing must be completed before you begin operating under the assumed name. The Secretary of State will process your DBA application and issue a certificate of registration. You should keep this certificate with your business records and renew it as required by Texas law to maintain your right to use the trade name.
Name Approval Timeline and Processing
The Texas Secretary of State typically processes LLC name filings within 1-2 business days for standard online submissions. However, if your name raises any distinguishability concerns or includes restricted words, processing may take longer as the Secretary of State reviews your application more carefully.
If the Secretary of State rejects your name, you will receive notice explaining the reason for rejection. Common rejection reasons include:
- Name is not distinguishable from an existing entity
- Name contains a restricted word without proper authorization
- Name lacks the required LLC designator
- Name contains prohibited characters or formatting
You can then resubmit with a revised name or provide additional documentation (such as regulatory approval for a restricted word). Resubmissions are processed in the same timeframe as initial filings.
Filing Your LLC Name with the Secretary of State
You submit your LLC name as part of your Articles of Organization filing with the Texas Secretary of State. The Articles of Organization is the foundational document that establishes your LLC and must include your chosen name exactly as you want it to appear in the state records.
You can file your Articles of Organization online through the Secretary of State's website at https://www.sos.state.tx.us/corp/sosda/index.shtml or by mail to:
Texas Secretary of State
P.O. Box 13697
Austin, TX 78711-3697
Online filing is faster and recommended. The filing fee for Articles of Organization is separate from any name reservation fee. Once your Articles are approved and filed, your LLC name is officially registered and protected under Texas law.
