Please be aware that I am not an accountant and the below information reflects my understanding of the situation. I highly recommend reading the links I’ve given at the end.
On 1 January 2015, European VAT law is changing. Instead of the old method of applying VAT at the seller’s location, it will now apply to the buyer. This means that if you sell directly to anyone in Europe, you will be liable to pay VAT to their country’s government – with all the administration that entails, including detailed record-keeping and quarterly returns to each of the 28 countries if you’ve sold even one item in each. Not fun!
