Readers' forum: Bright spark

My client sells lampshades and other light related goods through Amazon. Basically he delivers his goods to an Amazon warehouse in the UK but if the goods are ‘top sellers’ Amazon will transfer some of the items to hold as stock in its warehouses in Germany Spain Italy or France. Thus they are available at short notice to meet orders from customers in those countries.

My concern relates to VAT. When goods are sold Amazon sends a delivery note to my client also confirming the amount of the sale so that we can account for output tax on his UK VAT return. However correspondence received from the German tax authorities suggest that the client should be VAT registered there.

Can Taxation readers shed some light on this dilemma? And how will Brexit affect this arrangement? My client is adamant that he does not know...
