All our orders are processed by our official e-commerce resellers (2Checkout and Paddle) and according to EU regulations, all customers located within the EU are required to pay VAT unless they have a valid VAT ID, in which case they are exempt from VAT.
For a list of EU members and their standard VAT rates, as well as more details on the VAT Regulations, please check out the full documentation and the European Commission Jan 1, 2015 Updates.
