Opencart 2.0.3.1 (Different Tax for Options)

Hi all,

I am setting up a software store and for software paper licence, each product should have 5% VAT & 14% Service Tax to be charged. No problem with this. Works perfect.

But some software has a maintenance option as a service that can be bought. However there cannot be VAT component for maintenance being a service; Only 15% Service Tax can be charged on maintenance.

Currently if I add maintenance as options, it adds both VAT as well as Service Tax to maintenance cost;

How can this be fixed?

Thanks in advance.
