Does it make a difference regarding VAT added to the mint price if the mint is done from the buyer’s website or a third-party platform in a different jurisdiction?

It depends on the qualification of the underlying service for VAT purposes. In principle, the
creation of tokens and their sale to consumers can constitute digital supplied services, according to
Art. 58 of the VAT Directive (2006/112/EC). If NFTs or other tokens are sold via a platform, Art. 9a of
the VAT Regulation (EU No 282/2011) can be applicable. This shifts the VAT liability from the creator
to the platform operator. If this is a transaction subject to VAT, traders from third countries must also
report VAT, the so-called destination principle applies.
