Do I need a DBA in California?
If a business is located in California and is using a Fictitious Name, then it is required to register a DBA (Doing Business As) in the county where the business is located.
For sole proprietors and partnerships, a DBA must be filed if the DBA name is something other than the names of the legal owners of the business.
For LLCs and Corporations, a DBA must be filed if the DBA name is something other than the legal name listed on the formation paperwork or articles of incorporation.
DBA’s are not required for running a business, but are often used to branding purposes or companies that want to expand and branch out.
However, anytime a name other than the legal name on formation documents is used, it must be legally registered as a DBA name.
