Using Hikashop 4.4.0. As I realize, tax with free shipping coupon is not corect. So at checkout shipping tax is still there. Final sum is ok.
I set free shipping coupon. We have 22% tax on shipping.
Example on checkout:
Coupon-2,50 €
Shipping cost (here is 22%vat)2,50 €
VAT 5%0,95 €
VAT 22%0,45 €
Shipping byout (here is no vat)1,20 €
To pay21,10 €
There is in total 0,45€ of 22% vat. It should be zero 22% vat.
