- The NFT represents the digital ownership of the underlying digital file.
- The transaction involves the sale of the digital certificate of authenticity, not the physical or digital file itself.
- The services of digital art, specifically the sale of NFTs, are considered electronically provided services that are subject to a 21% tax rate.
