Türkiye charges its own citizens a departure fee, the yurt dışı çıkış harcı, each time they leave the country; foreign nationals do not pay it. Unless you are exempt, it must be paid before every departure, and police officers check the payment or exemption at the exit gate. Fee stamps are no longer used, so the fee is now paid through the Digital Tax Office, GİB Mobil, a bank, PTT or a tax office counter.
This guide shows how to pay on the Revenue Administration's password-free Quick Payments screen, how to pay for a whole family at once, who is exempt, what is checked at the exit gate, how to confirm that your payment has reached the police, and how to ask for a refund if your trip is cancelled.
