Taxation in various countries differs considerably, and requires a quite different structure for the calculation. For technical reasons, Kartris has this value set in the web.config rather than in the config settings, meaning it is not changeable from the back end of Kartris.

This value gets set during the setup routine, and it's unlikely most stores would ever need to change this. But if for any reason you do, you can find the tag in the web.config file and change it manually.

The possible values are:

• EU
  
• US
  
• Canada
• SIMPLE
