Avalara has been set up to determine the Tax for the Sales Order into the system. However, Avalara calculates the Tax on the Net Value and Freight value, whereas you expect it should calculate only on the Net Value.
You reached out to the Avalara, they provided below feedback:
"SAP is not able to pass the <TaxCode/> code at the line level, hence Avalara can not filter the Tax calculation" , I have also attached the Request data the we have received from the Avalara.

When we use Avalara we send the price lines , freight lines along with orgin , destination codes only. We do not send a tax code along with it.
This might be an issue with the freight tax code mapping in your Avalara configurations.
The payloads of request and response from our internal systems using Avalara to not include freight for the state CA. Checking them its clear we do not need tax code in the request payload. It might be more to do with the configurations.
The configurations in Avalara are not done by us and we only work with the external payload returned to us by Avalara. Please reach out to Avalara on how this should be done.
