Starting October 1: Some business services are now subject to retail sales tax, as required by state law, ESSB 5814. When you buy these services, vendors should add sales tax to your bill. If you sell these services, you should begin collecting retail sales tax. Learn more about Services newly subject to retail sales tax.
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:
- 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 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.
