What is a DBA (doing business as)?

The acronym DBA means ‘doing business as.’ It is the term for any registered name a business uses that is not their legal name.

The legal name of a company depends on its structure. It is the name of the company for LLCs and corporations. For sole proprietorships, the legal name is their own name.

A DBA can also be called a fictitious business name, trade name, or assumed name. In Delaware, it is primarily referred to as a business trade name. A DBA only changes the name of a business and nothing else.

For instance, when you open a business, it will default to your legal name (e.g., Kay Jones). Kay Jones is opening a convenience store. She doesn’t want the name of her business to become Kay Jones. So, she files a DBA in Delaware to change the business name to Kay’s Korner. Kay’s Korner becomes the name of her convenience store. Nothing else about the business structure of Kay’s Korner changes. Registering the DBA allows the business owner to operate using a trade name.

  • Filing a DBA is how a business operates under a name that isn’t its legal name.

Who needs a DBA?

Delaware requires that all businesses that wish to operate using a trade name file a DBA. It includes all sole proprietors, LLCs, partnerships, and corporations.

Registering a DBA is a good idea for businesses and is dependent on the owner’s needs, state and local requirements, and business structure.

  • New businesses. If you wish to use a trade name in Delaware, you must file a DBA. DBA names in Delaware must be unique and meet state requirements.
  • Sole proprietors. A sole proprietor shares the name with their business unless they file a DBA. It is because a sole proprietor and their business are the same legal business entity.
  • LLCs. In Delaware, LLCs must file a DBA if they wish to expand and operate separate businesses that do not want to use the company’s name. In the absence of a DBA, every new business your LLC buys and operates would have to use the legal name of the LLC regardless of the line of business.
  • Corporations. Corporations utilize DBAs regularly. It is because they operate businesses in a variety of industries. A corporation has to do business under the name of their company unless they file for DBA names.
  • Franchises. Franchises use DBAs all of the time. For instance, if you purchase a Dollar General franchise. Dollar General is an LLC. The new franchise would be listed as “907 Business LLC”. A DBA must be filed to change the franchise from the numerical listing to Dollar General Store. It alerts the state of Delaware that you’re ‘doing business as’ the franchise.

A DBA gives a small business owner the creative freedom to name their company.

DBAs also help startups and entrepreneurs avoid the costly and complicated process of forming an LLC or corporation to just use a different name for their business.

Why do you need a DBA?

  • DBAs help keep things simple. A DBA only changes the name of a business. However, they help small businesses in other ways, too. DBA registration is a straightforward and low-cost way that a sole proprietor can use to operate utilizing a trade name as the business’s name without having to form an LLC or corporation.
  • Limited liability companies (LLCs) and corporations benefit from a DBA. Delaware requires that LLCs and corporations file for separate DBA names for every business they wish to operate using a name other than the company’s name. For example, Joe’s Coffee Beans LLC wants to open The Morning Rise’s coffee shop. The LLC must file a DBA to change the name. The Morning Rise remains owned by Coffee Beans LLC.
  • A DBA helps alleviate privacy concerns. If you do not register a DBA in Delaware as a sole proprietor, you will have to use your personal legal name on public-facing materials. A DBA allows you to use your trade name on signage rather than your legal personal name.
  • Business banking is made easier with a DBA. Financial professionals recommend that all new businesses and startups open a separate business bank account from their personal one. It protects your personal assets and credit scores. Also, most banking institutions require new owners to register a DBA name before opening a bank account in the company name. A DBA does not offer any legal protection on its own.
  • Registering a DBA name makes branding simple. You draw in customers using the best branding and marketing tools available. Your signs, flyers, and business cards tell your customers or clients about the products or services you sell. You must file a DBA to use the trade name that best advertises your business. For example, if Kay Jones had not filed a DBA, her customers wouldn’t know or understand that she runs a convenience store.
