If you leave the European Union (EU) and have your residence outside the EU, you can have the value added tax reimbursed for goods that you have purchased in the EU. For the refund you require a U34 form, on which the export is confirmed by customs, and the bill. On presentation of the export confirmation at the bank, you then receive a cash payment of the value added tax minus a fee. Outside bank opening hours you can hand in the application for payout at the Information Desk. Attention: Here there is no cash payout, the documents are merely forwarded!
In Austria, for the purchase value there is a minimum limit of EUR 75.00.

Only goods may be transported in the hand luggage, that are exported directly from the EU. Otherwise the goods must be transported in the checked-in baggage. Notify staff at Check-in, that you require the export confirmation from customs for items in the luggage, as the goods must be confirmed before checking-in.
