One of the first and most common reasons Texas LLC filings get rejected is the name. Texas requires your entity name to be “distinguishable” from every other entity on file. Here is the exact process founders use in 2026.
Step 1: Search for Name Availability (Free)
- Go to the official Texas SOSDirect (free public search available without full login in many cases).
- Search the exact name you want (without the LLC designator first).
- Search variations: singular/plural, abbreviations, reordered words, common misspellings.
- Also run a general web + USPTO trademark search + county clerk assumed name searches in the counties where you’ll operate.
Tip: The SOS will reject names that are “deceptively similar” even if not identical. When in doubt, add distinctive words (location, service type, made-up brand element).
Step 2: Name Reservation (Optional but Smart)
File a name reservation with the SOS for $40. It holds the name for 120 days (renewable). Great if you are still finalizing operating agreements, raising money, or ordering signs/websites before filing the actual Certificate of Formation.
Reservation form is available through SOSDirect. A reserved name gives you priority and reduces last-minute panic.
Texas LLC Naming Rules You Must Follow
- • Must contain “Limited Liability Company”, “LLC”, “L.L.C.”, “Limited Company”, “L.C.” or “LC”
- • Must be distinguishable from existing Texas entities (including foreign entities qualified in TX)
- • Cannot imply a purpose different from what’s in your Certificate of Formation
- • Restricted words (bank, trust, insurance, university, college, etc.) require pre-approval or special licensing
- • No obscene or misleading names
- • You can use “Company” or “Co.” but still need the LLC designator
Assumed Name (DBA / “Doing Business As”) in Texas
If you want to operate under a name different from your legal LLC name (e.g., “Lone Star Coffee LLC” doing business as “Austin Roasters”), you generally file an Assumed Name Certificate (Form 503 or county equivalent).
- For state-level entities, file with the Texas Secretary of State (Form 503) and with the county clerk(s) where you conduct business.
- County filing is usually required even if you file at state level.
- Fee at county level is typically low (~$15–$25 per county).
- Renewal is usually every 10 years, but verify with your county.
