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. In Washington state, this name is officially referred to as a Trade Name.

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

What is a DBA good for?

A DBA is required for many businesses in order to legally operate and provides information on the people operating a business.  In addition to the legal requirement, a DBA offers other benefits such as proving the existence of a business, opening a business bank account, registering a merchant account to accept credit cards, and others.

Who needs to register for a Washington Trade Name?

The requirements and need to register a Trade Name are organized under Washington Statutes 19.80.  These requirements vary depending on the type of business entity.

Sole proprietorships and general partnerships are the most common entity to register for a Trade Name.

The legal name of a sole proprietor or general partnership can be the owner’s full first and last name, which can be used without registering.  For example, if Helen Wheels starts an auto repair business operating under the name Helen Wheels she doesn’t need to register.  If Helen decides to name her business Helen’s Auto Repair or even Helen Wheels Auto Repair, then she will need to register.

Corporations and Limited Liability Companies won’t typically register a fictitious name 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.

Does a DBA need an EIN?

An EIN or Employer Identification Number is a unique nine-digit number that some businesses will register for through the Internal Revenue Service (IRS). An EIN is required for partnerships, corporations, multi-member LLCs, or any business that has employees.
