How to file an assumed name (DBA) in Texas
By the Fair Permits licensing team · Updated · 3 min read
Short answer
A Texas business that operates under any name other than its exact legal name needs an assumed name certificate (a DBA). LLCs, corporations and limited partnerships file Form 503 with the Texas Secretary of State for $25. Sole owners and general partnerships file with the county clerk where they do business (about $25 in Harris County, about $15 in Fort Bend). A certificate lasts up to 10 years.

When you need one
If the name on the sign, the receipts or the bank account is not the company's exact legal name, Texas requires an assumed name certificate. "ABC Ventures LLC" operating a store called "Quick Stop Food Mart" needs one for "Quick Stop Food Mart". If you are unsure whether a shortened version of the legal name counts, file the certificate; it costs $25 and removes the question.
Getting the name right matters for the other permits. The sales tax permit, TABC permit, lottery license and SNAP authorization each show a business name, and agencies compare them. A mismatch between the sign, the DBA and the permits is a common reason for a TABC deficiency notice.
Where to file
| Who | Where | Fee |
|---|---|---|
| LLC, corporation, limited partnership, LLP | Texas Secretary of State, Form 503 | $25 |
| Sole owner or general partnership | County clerk of each county where the business operates | Set by the county (Harris about $25, Fort Bend about $15) |
Companies used to file in both places. Since September 1, 2019 (House Bill 3609), an entity files only with the Secretary of State; county clerks no longer take entity filings.
How to file
- Check the name. Search for conflicts and decide on the exact spelling and punctuation you will use on every permit.
- Complete the certificate. For an entity, Form 503 lists the assumed name, the company's legal name, file number, registered agent, the counties where it uses the name, and how long the name will be used. An officer, manager or other authorized person signs.
- File. Online through the Secretary of State's portal or by mail, with the $25 fee. Sole owners take the county form to the county clerk, often signed before a notary.
- Keep the certificate with the company records. Banks ask for it to open an account in the business name.
Filing usually takes a few business days.
How long it lasts
An assumed name certificate is effective for the period stated on it, up to 10 years. Renew it before it expires if you still use the name, and file an abandonment if you stop. If the company's details change (a new registered agent or address), file an amendment.
