DBA is a shortened acronym that stands for ‘doing business as.’ A DBA is a registered name that a company or individual uses to do business under that is not their legal name.

The legal name of a company is different depending on the business structure. For a limited liability company (LLC), the legal name defaults to the company’s name. For sole proprietors, the legal name is the individual’s personal name.

A DBA is sometimes called a fictitious name, trade name, or assumed name. In South Dakota, they keep it simple by referring to a DBA name as a business name.

For example, if you open a business, the legal name will be your own name (e.g., Amanda Jones). Amanda Jones wants to open a candy shop. She doesn’t want the business’s name to be her name, Amanda Jones. So, she files a DBA in South Dakota to change the name of her company to Mandy’s Candies. Mandy’s Candies is now the name of the business.

The DBA changes absolutely nothing else about the business. The DBA only allows Amanda Jones the freedom to use a business name that best describes what she offers.

DBA vs business name

  • A business name, or DBA, is how businesses operate using a name that is the business’ legal name in South Dakota.
  • The only difference between a DBA name and a business name is that a DBA is only an alias.
  • A DBA must be associated with a legal business entity.
  • A DBA and a business name are the same things in South Dakota.

Who needs a DBA?

South Dakota requires all sole proprietors, partnerships, corporations, LLCs, LPs, and LLPs to register a DBA name if they plan to conduct business using any name other than the company’s legal name.

A DBA benefits a business in various ways. The benefits depend on the business structure and the owners’ personal preferences.

  • New businesses. South Dakota requires new businesses to acquire a DBA before operating using a different name. DBA registration is a recommended business practice for all new companies.
  • Sole proprietors. Without a DBA, the business name for a sole proprietorship defaults to the owner’s full legal name. It is because they share the same legal entity with their business.
  • LLCsAll LLCs in South Dakota must register a DBA name when operating a new business outside of their primary LLC. Without a South Dakota DBA, every company that an LLC owns and operates would share the LLC name.
  • Corporations. A DBA allows incorporations the freedom to operate companies in various industries and many types of business. In South Dakota, a corporation that intends to run a company using a company name that isn’t the corporation’s name must register a DBA.
  • Franchises. Franchisees utilize DBAs. For example, if you buy a Little Caesars franchise. Little Caesars is an LLC. The new franchise would be listed as “5751 Business LLC”. To change the franchise from the numerical listing to simply Little Caesars, you will need to file a DBA to alert South Dakota that you now are ‘doing business as’ the franchise.

A DBA allows a small business owner or startup the creative freedom to choose their business name. A DBA also gives entrepreneurs the benefit of avoiding the costly and time-consuming process of forming and registering an LLC just to use a new name.

Why do you need a DBA?

  • A DBA helps keep things simple for small business owners and startups. A DBA only changes the name of a business. However, a DBA accomplishes more than that. Filing a DBA is a straightforward and cost-effective way for sole proprietors to use a business name without the complication of forming a separate LLC or corporation.
  • LLCs and corporations benefit from DBAs. A limited liability company (LLC) would have to form separate LLCs for each business it purchases without a DBA. For example, Vick’s Rubber LLC wants to open a tire shop named Tough as Tires. The LLC would file a DBA in South Dakota to change the name. Tough as Tires would remain owned and operated by Vick’s Rubber.
  • A DBA protects the privacy of sole proprietorships and general partnerships. In South Dakota, sole proprietors and co-partnerships must use their full personal names on public-facing material unless they file a DBA.
  • A DBA simplifies business banking. Most financial institutions and banks require companies to file a DBA before opening a business bank account. It is safest to open a bank account for a new business because it separates your business banking account from your personal business account. It is recommended to protect personal assets and credit scores. A DBA by itself offers no legal protection or liability protection.
  •  A DBA keeps branding affordable and straightforward. Your brand name is what alerts your audience that you exist and leaves the first impression. The company name listed on signage and business cards tells potential customers what you offer. For example, had Amanda Jones not filed a DBA, her customers would now know she opened a candy shop.
