Set shipping as non-taxable
You can set the Shipping total to be a non-taxable part of any Order. This means that your calculated tax total will not include the shipping amount you have entered for the order.
To set Shipping as a non-taxable component:
1. Navigate to your Order (or create a new Order)
2. On the form that appears, click the T icon to the right of the Shipping total textbox so that it appears crossed out.
3. Save the Order by clicking the Save Order button at the bottom of the page.
