DBA (Doing Business As)

The acronym “DBA” stands for “Doing Business As” and allows your business to operate under a different legal name. If you run a sole proprietorship or partnership, the legal name of your business is, by default, your actual name. If you have an LLC or Corporation, your legal name is the company name that you registered with the state. Here’s a quick breakdown:

  • If you are operating a Sole Proprietorship (a.k.a. the sole owner of your business), the legal name of the business is your full birth name.
  • If you are operating a Partnership, the legal name of the business is the name given in your Partnership Agreement or, if this does not exist, the last names of the partners of the Partnership.
  • For LLCs (Limited Liability Companies) and Corporations, the business’ legal name is the one that was registered with the state government.

If you would like to continue operating your business as a sole proprietorship or partnership but do not want your legal business name to be your actual name (e.g. – John Smith), you can register a DBA or “Doing Business As” name. If you have already formed an LLC or corporation, you can change the name that your company operates under by filing a DBA with the state that you registered your business in.

In short, a DBA (“Doing Business As”) name, also known as a fictitious name, is a business name that you create that is different from your personal name (Sole Proprietorship), the names of your partners (Partnership) or the officially registered name of your LLC or corporation. Like LLC’s and Corporation registration, DBA names must be registered through your state government.
