What is a DBA (doing business as)?

The acronym for DBA stands for ‘doing business as.’ It is any registered name that a company or individual uses to do business that isn’t its legal name.

The legal name of a company differs depending on its structure. It’s the company name for a limited liability company (LLC). And, for sole proprietors, the legal name of their business is their personal legal name.

DBAs are also referred to as fictitious names, trade names, or assumed names. In Colorado, a DBA is most commonly referred to as a trade name. 

A DBA only changes the name of a business and nothing else.

For instance, if you own a business, its legal name is your own name (e.g., Frank Williams). Frank Williams is looking to start an industrial cleaning business. He understands that he can’t just use his personal name because people won’t understand the services he is offering. So, Frank Williams registers the DBA trade name Frank’s Fire Cleanup, and it becomes the name of his new business. It changes nothing else about the business structure or legal entity of Frank’s Fire Cleanup.

Frank Williams is able to operate under a new name, and it no longer defaults to his legal name.

DBA vs business trade name

  • In Colorado, a DBA is most often referred to as a trade name.
  • As a sole proprietor, you must register a DBA in Colorada if you wish to operate a business under a name other than your legal name.
  • Companies in any industry can register a DBA. It includes sole proprietorships, LLCs, corporations, franchises, and non-profits.
  • A DBA is a business alias. This means that a DBA and a business trade name are the same things.

Who needs a DBA?

Colorado law mandates that all sole proprietors, LLCs, partnerships, and corporations file a DBA if they wish to operate under any trade name that isn’t their legal name.

However, certain non-profits that file Articles of Incorporation in Colorado may not be required to register a trade name.

DBAS benefits all types of businesses in a variety of ways. It is also dependent on a business entity and the personal preference of a business owner.

  • New businesses. Colorado requires a new business to register a DBA if they want to operate under a different name that isn’t the legal name.
  • Sole proprietors. Sole proprietors share a legal name with their business unless they file a DBA. This is because sole proprietors share the same entity with their company.
  • LLCS. Without a Colorado DBA, an LLC would have to form a new company every time it purchased and operated a business using a different trade name.
  • Corporations. Corporations that intend to operate a business using a name that is not their company must file a DBA. Commonly, corporations use DBAs when they open and operate businesses in different industries.
  • Franchises. Franchises also use DBAs to operate under a name that isn’t the company name. For instance, if you buy into a Kentucky Fried Chicken franchise, it is formed as an LLC and listed as 888 Kentucky Fried Chicken LLC. In order to shorten the name to simply Kentucky Fried Chicken, you must file a DBA in Colorado.

Small business owners and startups benefit the most from filing a DBA. It is because it gives an individual the creative freedom to name their business. And, it helps eliminate the need for a small business to form an expensive and complicated LLC to merely change the name.

Why do you need a DBA?

  • DBAs help to avoid the complicated and expensive process of forming a separate LLC. A DBA is a cost-effective and straightforward way for a sole proprietorship to operate using a different business trade name.
  • DBAs benefit corporations and LLCs. DBAs allow LLCs the freedom to operate various businesses without having to form a separate LLC for every company they wish to run. For example, if Johnathan’s Soda LLC opens a soda bar called Fresh Spring. To operate the soda bar under a business trade name, the LLC must register a DBA name in Colorado.
  • DBAs protect the privacy of the business owner. A sole proprietor in any line of business must put their own name on public-facing material unless they register a DBA name.
  • A DBA separates your personal assets from your business assets. DBAs do not offer any legal protections or liability protection on their own. A DBA does prove that your business assets and personal assets are independent of one another and decrease personal liability.
  • A DBA makes business banking easier. Banking institutions require you to register a DBA in order to open a  separate business bank account. Also, it is a best business practice to open a separate business bank account from your own to protect your assets and credit scores.
  • A DBA makes branding easier in Colorado. Initially, you catch the attention of potential clients with the name of your business. For example, without a DBA, Frank’s Fire Cleanup would be his name, Frank Williams. In Colorado, a business owner must register a DBA before legally using a business trade name or claiming a brand name.
