When does a corporation or limited liability company (LLC) file a DBA?
File a DBA registration if your company intends to do business under a name other than the legal name that appears on the corporation’s or LLC’s state-approved incorporation documents or foreign qualification documents (if registered to transact business in a state other than the state of incorporation). The corporation or LLC must file the DBA with the appropriate state and/or county agency in the state in which the company is formed or foreign qualified.
