Selling your goods to private individuals, e-commerce sellers, in multiple countries – especially in the European Union – creates VAT compliance obligations in multiple countries. It is illegal to trade in a country where you should be VAT registered but don’t have a VAT number. Tax authorities in the EU and across the world are implementing measures to identify and penalise non-compliant businesses, including forcing platforms such as Amazon and eBay to close accounts of non-registered sellers. Therefore, it is fundamental that your business registers for VAT wherever required.
