In Washington, as in most states, the primary step in creating a limited liability company (LLC) is to file a certificate of formation with the state. This is an absolutely crucial document that helps define your business, so it’s important to do it correctly.

An LLC is a business entity that offers liability protection for owners, as well as pass-through taxation, much like a sole proprietorship.

The certificate of formation is a legal document you need to file with the state to form your LLC and officially become a legal entity. It will specify details about your company and establish your LLC as a registered business entity in Washington. 

The document is similar to the articles of incorporation you would file to form a corporation instead of an LLC.
