What is tax-free shopping? / Shopping tax-free is, in essence, claiming a VAT (value added tax) refund after you have paid the VAT in-store.

VAT is a consumer tax and varies between 4% and 27% in the EU. You are eligible for a VAT refund if you live outside the EU and export goods to your country of origin. A VAT refund is only possible over goods, not services. The VAT is included in the purchase price. You therefore pay it in the store and claim it back afterwards.
