You are able to configure the default tax settings by navigating to Finance Settings within the Configuration tab of the Operator Portal.
These changes allow you as the Operator to set the specific default tax percentage on Postage, Merchant Fee, Commission and Items. Importantly, the Item code is a default rate and if you have set a tax rate on Category, this will take precedence.
Changing these setting will not change historic records and will only apply to orders placed or created after the settings have been changed.
Changes to these settings are stored in the Audit Logs which can be found within the Reporting tab of the Operator Portal.
