Amazon provides VAT refunds to business customers only in Italy who are eligible.
If a business customer is registered for VAT, they can request a refund for purchases made on Amazon.it that are eligible for VAT refund. The process for claiming the VAT refund involves submitting a reclaim form to Amazon, along with any necessary information or supporting documents.
Kallis, I’ve heard that in order to claim VAT in Italy, you must spend at least €154.94 at a single store; otherwise, you are not eligible for a VAT refund. Remember that this minimum applies to each shop, not to the total of your purchases throughout the trip. So, if your business customer has purchased something from you for more than €154.94, then he can apply for the refund.
