Are EU exports not exempt from the EU VAT?
VAT isn't charged on exports of goods to countries outside the EU. In these cases, VAT is charged and due in the country of import and you don't need to declare any VAT as an exporter. However, when exporting goods you will need to provide documentation as proof that the goods were transported outside the EU. Such proof could be provided by presenting a copy of an invoice, a transportation document or an import customs record to your tax authorities.
You will need to provide this proof to be able to fully deduct any receivable VAT that you have paid in a previous related transaction leading up to the export. Insufficient documentation may mean you won't have the right to a VAT reimbursement when exporting goods.
