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 Guide to get information and links that will help you do the following:
- Create your business structure with the Washington Secretary of State. (Skip this step if you are changing to a sole proprietor or general partnership.)
- 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.
- Reapply for any applicable specialty, city, or county licenses (for example, liquor licenses).
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 and Industries.
