KTO's official guide states that immediate tax refunds require a transaction of at least KRW 15,000, below KRW 1 million per purchase, and total purchases not exceeding KRW 5 million. Passport verification precedes payment of the tax-deducted amount. Confirm eligible shops, items and current limits at checkout.
Refund rules and available providers can change. Recheck the official KTO guidance and the participating shop or hotel before purchase.
