Travellers who are not resident in Turkey can claim a refund of the tax paid on many goods bought in the country. At the airport this is a two-counter job in a fixed order: the customs desk stamps your paperwork, and only then does a refund point pay you. Get the stamp before your purchases disappear into the hold.
Who can claim
The refund is for travellers not resident in Turkey, on goods bought in the country and taken out with them. It is not the same thing as duty-free shopping: goods bought in the duty-free stores after passport control are sold without the tax in the first place, so there is nothing to reclaim on them. The refund covers what you bought in ordinary shops in the city.
The three steps
The airport sets out the process in three steps, and each one has a thing you must have in your hand.
In the shop. When you buy the product, ask the shop staff for a tax refund check. A shop that cannot issue one is not part of the scheme, and no stamp later will fix that.
When you leave Turkey. Present your purchases, the tax refund check and your passport at the customs desk, and have them stamped.
After stamping. Present the stamped check, your passport and your credit card at Global Blue Customer Services or at a partner refund point.
Why the order matters at an airport
Step two says to present your purchases. That is the step travellers lose, because it only works while the goods are still with you — once a suitcase goes over the belt at bag drop, you can no longer show what is inside it. If the things you are claiming for are going into checked luggage, the customs stamp has to happen first.
The same logic sets your timing. Two counters, in sequence, before a flight that is also asking you to check in and clear security, is not a five-minute errand — see how early to arrive for the rest of that calculation.
What the airport does not publish
Three things travellers reasonably expect to find here, and where they actually come from:
Where the counters are. The airport names the customs desk and Global Blue Customer Services but does not publish their location by terminal, or their hours. Ask at an information desk on arrival in the departures hall rather than planning around a floor plan that does not exist.
The minimum purchase and the refund percentage. These are set by Turkish tax legislation and by the refund operator, not by the airport, and the airport publishes neither. The terms that apply to your purchase are the ones printed on the check the shop gives you — read it in the shop, not at the airport.
Which shops take part. Being handed a tax refund check is the test, and it happens at the till.
The operator
The refund point the airport names is Global Blue, alongside unnamed partner refund points. That matters for one practical reason: your check is issued by a specific operator, and it is paid by that operator's desk. A check from one scheme is not redeemable at another scheme's counter, so the name printed on your paperwork decides which queue you join.
