We need to apply a custom shipping tax rate to the shipping amount. Present i configured flat
12% tax on shipping prices but i need to take highest tax percentage from all the products in
cart/checkout and needs to apply it.
For example in my cart page i have
two products which is under following tax rules.
Product A - 5% tax Product B - 12% tax
In this case i need to take
12% tax and added it to the shipping amount. How can i proceed on this?
