Tax Zone

What is the difference between setting the Main Tax Zone in configuration with a specific country and clicking System > Taxes > Click New and setting the Zone there?

Do you need to set both for the tax zone in your country?

Hi,

1. As the documentation say :

You need to select your zone here. Some countries might have different taxes on a per-state basis so you will want to specify here your state rather than your country. That parameter will be used to calculate taxes. Also, before a customer enters his address, the system will also use this zone as the customer zone to calculate taxes
