We have 2 sales orders for the same customer/ship to address. The customer is in Canada so they are subject to GST Tax. The GST tax is calculated for both orders. But on one order the tax is calculated based on the item subtotal and on the other order it is based on the item subtotal AND the freight amount.
The sales tax in the company setup is set to "Use shipping method when selecting Default tax Schedule". So I checked and the ship method on both orders is the same.
Is there something else I can check to see why the tax is only including the freight on SOME but not all orders?
Thank you!
