Who needs to register for a Washington Trade Name?

Washington Statutes 19.801 outlines the requirements for registering for a Trade Name, and these requirements vary depending on the type of business entity.

Sole proprietorships and general partnerships are the most common business structures to register for a Washington DBA. By default, the name of a sole proprietorship and general partnership is the owner(s) legal name. If the small business owner wants to operate under a specific name, they will need to complete the Trade Name registration.

For example, if Helen Wheels starts an auto repair business operating under her legal name, Helen Wheels, she doesn’t need to register. However, if she decides to name her business Helen’s Auto Repair or even Helen Wheels Auto Repair, she will need to register.

Corporations and Limited Liability Companies won’t typically register for a Washington DBA since a unique entity name is created during the entity formation process. However, some will want to register for a DBA if they have another business or brand name they want to operate in addition to the legal name of the business. This can allow multiple businesses to operate with the liability protection of a Washington corporation or Limited Liability Company without having to form another entity.

What are the steps to file a Washington Trade Name?

Step 1: Verify Name Availability
