What is a DBA?

A DBA, also known as “Doing Business As”, Trade Name, Assumed Name or Fictitious Name is a name used by a business, that is different from the legal name of the business.   This name is often referred to as an Assumed Name in Kentucky.

When a business wants to operate under a name other than their legal name, the state of Kentucky, like most states, require the business to register their business name.  The registration requirement was designed to protect consumers from business owners hiding anonymously behind the name of a business.

Who needs to register?

The requirements and need to register for an Assumed Name vary, depending on the type of business entity. 

Sole proprietorships will commonly register for a DBA. 

The legal name of a sole proprietor can be the owner’s full first and last name, which can be used without registering.  For example, if John Smith starts a business repairing computers but doesn’t use a business name he doesn’t have to register.  If John decides to name his business John’s Computer Repair then he will need to register. 

General Partnerships, Corporations and Limited Liability Companies – General Partnerships will commonly register a DBA, however corporations and LLCs won’t as often since a unique entity name is created during the formation process.  Some will file for a DBA if they have another business they want to operate under their corporate/LLC umbrella to keep the liability protection without having to form another entity.
