Change your business structure

The process to change a business structure (for example, change from a sole proprietorship to a corporation) is the same as starting a new business.

Use the Business Licensing Wizard to get information and links that will help you do the following:

  1. Create your business structure with the Washington Secretary of State. (Skip this step if you are changing to a sole proprietor or general partnership.)
  2. Submit a new Business License Application to apply for a new Business License. You will be given a new Unified Business Identifier (UBI) number to be used on tax returns and other documents.
  3. Reapply for any applicable state, and/or city endorsements (for example, Nursery endorsements in Lakewood).

Note: You will probably need to re-apply for all of the licenses you currently have. For example, if you are a building contractor, you will need to reapply for your contractor’s license with the Department of Labor & Industries.
