Washington Articles of Organization

Articles of organization form your Washington LLC.

Preparing and filing your articles of organization is the first step in starting your limited liability company (LLC). Approval of this document secures your business name and creates the legal entity of the LLC. Only after this approval can you obtain a Federal Tax ID (EIN), open a bank account, sign contracts, and otherwise conduct business.


Incorporating provides many important benefits:

  • Limits the liability of the members (owners) and managers
  • Fulfills statutory requirements to register your business name
  • Adds credibility
