Hello,
we had setup german tax and also tax on shipping cost. If we try to use a discount who will reach the full amount of shopping cart discount not working for shipping cost tax. It always display shipping tax on shopping cart... could anyone help?
It seems that disocunt wont apply to shipping cost tax. Only tax... 
I had also attach all settings.
So we had setting the tax page:
the shipping page:
setup a discount:
screen of checkout:
Here you can see it will use discount but the tax from shipping cost cant discount ...and i dont know why?
