When you are selling your goods online via an online marketplace, the rules may deviate from the general VAT regulations for e-commerce in Europe.
Sales of goods made via an online marketplace such as Amazon or eBay will, in some cases, make the marketplace liable for VAT on that supply. This means that it is the marketplace, and not the seller, who will collect VAT from the final client and transfer that VAT amount to the relevant tax authority.
