In Washington, a business operating under a fictitious name will need to register a DBA.  Learn more about what a DBA is, who needs one and how to register.

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.   

When a business wants to operate under a name other than their legal name, the state of Washington, 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 an Assumed Business 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 entities to register for a DBA. 

The legal name of a sole proprietor or partnership 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 operating under John Smith he doesn’t need to register.  If John decides to name his business John’s Computer Repair or even John Smith’s Computer Repair then he 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.

How much does it cost to register?

The fee to register a Trade Name is $5.  If starting a business, this $5 is in addition to the $19 business license application fee.

Name Restrictions

DBAs can’t be registered using words that are related to banking unless the business is licensed to provide those services.  

Protecting your business name

While registering your Trade Name will keep someone else from registering the exact same name in Trademark, it does very little from someone else operating a business under that name in other states.  If stopping others from using your business name is important, you can protect it through a trademark.
