There are two view files for the address format, one for the backend, and one for the frontend.
So both need to be modified.
However, since a few years back, you now have a setting "address format" understand the checkout tab of the HikaShop configuration.
So you should do the modification there (maybe it's already there) and save the configuration.
That will update / create automatically both view overrides for you and it should hopefully work fine after that.
I checked it again and it's both in the front and backend of the address_template files.
I just see save buttons, no other options and the {address_vat} line is there already.
Am I still missing something? It still doesn't add it to the emails (both customer as admin), but it's there when i check the order/contact in the interface.
EDIT: I also checked the address format and this is what it looks like.
