createTaxGroup( )

Creates a tax group.

Add the taxGroupId to specific Stores products to categorize a group based on distinct tax treatment. Wix uses tax groups to calculateTax().

In addition to tax groups you create, default tax groups are already included in all Wix catalogs. Use listDefaultTaxGroups() to retrieve them. You can also use the Tax Groups Integration service plugin to create new default tax groups that can be applied directly to an entire catalog of products.
