You’re probably saying, ‘but what about the chocolate flavour?’, which, due to the cocoa butter content, is zero-rated for VAT under EU VAT Directive rules and the UK VAT Act. HMRC won this case on the basis that the strawberry and banana flavours were not, as Nestle had argued, critical to the creation of a new beverage.
It’s still milk. Flavoured yes, but different to adding sugar to coffee due to its singular use. You can do a lot with sugar. So next time you’re in the supermarket and look at the range of Nesquik on the shelf you can be ‘glad’ that we now know why the chocolate flavour is zero-rated and its brethren not.
