To add DBA to LLC Washington State, you must submit your application to the State Business Licensing Service, along with the prescribed filing fee. Obtaining a DBA, or Doing Business As, allows you to conduct business in a separate name than your own legal name. A DBA is usually obtained by sole proprietorship businesses since companies and corporations already have a separate name as part of their identity.

How to File a DBA in Washington

Secure Your Brand Name

In Washington, you don't need to register a sole proprietorship business, that is in your own name. However, to set up a business under a different name than your own legal name, you must pay a fee of $5 and register it with the State Business Licensing Service.

Before registering your business name, perform a name search with the Washington Secretary of State in order to make sure that it's not the same as or too similar to an existing business name. You should also conduct a search with the USPTO (United States Patent and Trademark Office) in order to avoid violating someone else's trademark or brand name.

Complete the Application

Take a printout of your business license application. Make sure you fill out the form correctly. If required, use assistance from a professional or someone experienced. Sign the application and submit it to the state agency. Note that a filing fee of $19 must be paid for submitting this form. You can also apply online but even if you do so, it's better to keep a hard copy with you for your record.

If you need any clarification or information on the online application process, you should visit Washington State's Department of Revenue website, and sign up for an account.

Submit the Application Form

Once you have completed the application form for a business license, get it notarized and sealed by an appropriate authority.

Remember that before applying for a business license, you must have an Employer Identification Number (EIN). If you haven't obtained it yet, you can apply for one online through the IRS website.
