Hello, Gewoonbovenaan,
We have found that our code works the same way as the default WooCommerce’s one:
WooCommerce -> https://prnt.sc/EonmDapv-pBq
Ours -> https://prnt.sc/PycbLhCYKnsY
It means that showing the tax will be in those cases when next option -> https://prnt.sc/tV5Zg8iforlg will be set to “Excl.” because only in that way there are normal calculations of tax and if this option is set to “Excl.” then you will be able to modify the content of Emails with next shortcodes -> https://prnt.sc/_V2K6FFugOwp to get this result -> https://prnt.sc/CoM-IBq5iwSl
Do you prefer to switch that WooCommerce option and modify the content according to your needs or should we create some specific solution for the customers like you who wants to show “incl. tax” for Total of order ?
Kind Regards,
8theme team
