Tax Profiles
In a lot of countries, a product can attract multiple taxes. Tax Profiles make this easy by allowing you to club tax rates together. Also, you can define which address (billing/shipping) is the basis of each contained tax rate.
* To create tax profile, you must set up tax rates first.
* Once you create tax profile, it can be selected while adding a new product.
When a buyer purchases that product, all applicable tax rates from the selected tax profile will get applied while checkout/payment process.
You have disabled 'Taxation' option. If you want to use taxation, you have to enable it from Quick2cart options.
