How to File a DBA in Arizona (Requirement, Cost, Fees and Steps)

DBA stands for “doing business as.” A DBA gives you the legal backing to operate your business under a different name other than your own name (in the case of a sole proprietorship) or the registered name of your business. A DBA is only used for branding purposes. A DBA isn’t a type of business structure and won’t protect your personal assets.

Please note that you can apply for a DBA when you first register your new business, or you can apply for a DBA later on if you decide to make changes to your business. It is important to state that a business can use a DBA to advertise, transact business, and open bank accounts.
