A DBA ("doing business as") is a fictitious business name — the name a business operates under when it differs from its legal registered name. Unlike corporations and LLCs, DBAs are filed at the county level, not with the Secretary of State. This guide explains the process.
What Is a DBA?
- A trade name, not a legal entity. A DBA does not create a separate business structure or provide liability protection.
- Filed at the county level. Each county clerk maintains its own fictitious business name records.
- Required when the operating name differs from the owner's legal name or the entity's registered name.
Steps to File a DBA
- Search the county's records to confirm the name is not already in use in that county.
- Complete the Fictitious Business Name Statement with the business name, owner details, and address.
- File with the county clerk where the business operates. Fees vary by county (typically $40–$60).
- Publish the statement in a newspaper of general circulation in that county, usually for four consecutive weeks.
- File the proof of publication with the county clerk.
Renewal and Expiration
- DBAs expire after 5 years and must be renewed to stay valid.
- File a renewal before expiration if you want to keep using the name.
- File an abandonment if you stop using the name.
Important: A DBA does not protect your name statewide. Another business in a different county can register the same name. For statewide name protection, consider forming an LLC or corporation.
