Who needs to register for a Washington Trade Name?
Washington Statutes 19.801 outlines the requirements for registering a Trade Name, which vary depending on the type of business entity.
Sole proprietorships and general partnerships are the most common business structures for registering for a Washington DBA. By default, the name of a Washington 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 business’s legal name. 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.

Washington Trade Name FAQs
How much does a Washington Trade Name cost?
Registering a Washington Trade Name with the Washington State Department of Revenue is $5. If you are starting a business, the $5 Trade Name fee is in addition to the $19 business license application fee.
After registering the Trade Name, can someone use my business name?
While registering your Trade Name will keep someone else from registering the exact same name in Washington, it does very little to stop someone else from operating that business name in other states. If stopping others from using your business name is important, you can protect it through a trademark.

Does a DBA need an EIN?
An EIN or Employer Identification Number is a unique nine-digit number that some businesses register for through the Internal Revenue Service (IRS). An EIN is required for partnerships, corporations, multi-member LLCs, or any business with employees.
Sole proprietorships and single-member LLCs without employees can use the owner’s social security number to identify the business.
There is no cost to get an EIN when registering directly from the IRS.
Are there any words you can’t use in a Trade Name?
DBAs can’t be registered using words related to banking unless the business is licensed to provide those services.
