You are attempting to validate an exemption certificate but the error "Could not validate certificate. A Business Number Type under Customer Tax IDs must be provided." appears and all the information you entered disappears.
- You are a Streamlined Sales Tax (SST) participating customer, using Avalara as your SST CSP (Certified Service Provider), so you have additional requirements for the information required in certificate validation:
- Go to the Tax IDs tab (click < arrow in certificate validation)
- Make a selection in all drop down menus
- Click Validate
