The present invention relates generally to the field of computers and in particular to methods and systems for processing tax refunds. Existing VAT refund systems are either expensive or overly cumbersome with paperwork. The present invention provides a solution to these problems by providing a tax claim system comprising a payment card system 1 suitable for accepting payment card transactions at a point of sale, the payment card system comprising a display for displaying information to a payment card system terminal user. The tax claim system further includes at least one data capture device for receiving card details from a payment cardholder and an indication receiving element for receiving an indication that a tax refund claim is required for a transaction. The system further provides a claim generation module for generating a tax refund claim in response to a received indication that a tax refund claim is required for a transaction and communicating this generated claim to an associated printer device.
