I believe this is what you need to do: https://help.shopify.com/en/manual/taxes/tax-overrides#override-the-taxes-on-a-collection-or-on-ship...
To sum it up with my own words:
In this case, the tax will change for each products that belongs to the "tax overide" collection.
I read but I couldn't fix my issue, to resume it :
I sell beer bottles on Shopify
It includes both the beer liquid as the bottle ( empties)
When I sell a beer 2,5 VAT included it actually needs to be split, for accounting purposes as following
- 2,4 VAT 21% sale
- 0,1 VAT 0% sale ( for the empties)
/ How do I do this in Shopify ?
Is there any app that could split it ?
