Source: https://support.storeconnect.com/articles/tax-object-reference · Last modified 21 August 2026

## Overview

A Tax__c object represets a tax code used within StoreConnect and then can be associated with a specific product and zone. For example, you could have a tax code of "GST" which belongs to the Zone "Australia" which includes one Zone_Country "Australia". This would be then used against a product when the customer orders the product and their shipping address is found to be in Australia.
