If you buy a crate of apples and pay in oranges, you do not pay VAT on the ORANGES, you pay VAT on the APPLES.
The article explicitely states that "When using BTC as a MEANS OF PAYMENT, that PAYMENT is VAT-exempt" - NOT the goods you are buying!
For whatever reason they had to clarify this is beyond me.
I don't think that's right. Conventionally if you sell me a crate of apples and I pay you in oranges, IIUC there are effectively two taxable transactions going on: I'm selling you oranges, and you're selling me apples. So you have to charge me VAT on the apples I'm buying from you, and I have to charge you VAT on the oranges you're buying from me. (The way VAT works we may also get VAT credits that may cancel out, but that's a different issue.)
This is different from what happens if you sell me a crate of apples and I pay you in Euros. So the question was whether bitcoins were going to be treated like oranges or like Euros. Common sense obviously says they should be treated like Euros (or at least like a foreign currency) but it wasn't clear whether the letter of the legislation would allow common sense to apply here.
