I am creating custom module. In the Module Some Customer Groups doesnot apply the tax calculation and some custom functions. so i need to know the file name and function for tax calculation in cart and checkout page.


function is calcTaxAmount().

This the file and functions, you asked. and please dont make any custom code in core folder. it will affect your site when you update the magento version.
