Can I process requests for receipts issued in a previous fiscal year? /

Yes, you can process requests for receipts issued in a previous fiscal year.

If your customers receipt was stamped by customs within 3 months after the month of purchase, they are allowed to submit the receipt for a VAT refund until up to 5 years after the year of purchase. 

Our invoice for your customers VAT refund will be issued in your current book year. This way you can still help your customer get a VAT refund for an old purchase.
