For eg:
Product sales price = 100
tax A = 5%
tax B = 5%
tax Z = 12%
I need to add taxes A and B to the sales price ie 5+5=10%, adding it, total price will 110. This part is OK.
Then the Tax 12% is added on this price(110) not the original sales price(100). It is 13.2
The final price should be 110+13.2 = 123.2. How can I achieve this?
