1. Click on 'Tools' > 'Tax Zone' to create Tax Information such as 'Tax Name' and select various Zones with tax charges from the multi-selection menu.

  2. Define tax 'Rate' in percent. (Note : Taxes that applied to a zone will be multiplied). For e.g. 10% (tax rate) x $ 80.00 (product price), so the total amount will be $ 88.00. If there are other taxes incurred, it will also be added and give you a whole lump sum.

  3. Once you're done, click on 'Add' button. Created tax information will be displayed in the list that you can edit the 'Rate' in the textbox and update it at instant.
