There are no VAT refunds counters in airports anymore. We get request from international clients & tourists to not charge tax items as they’re not for domestic consumption. We should have the functionality of De-taxing GST on these purchases at the POS level itself. This is a common practise in many countries abroad. They usually ask for passport some declaration forms and process items without tax. Note: most items are liable duties and taxes in their destination country. Charging them taxes here is unfair and unnecessary burden on international clients
