To claim a VAT refund at Dubai Airport, visit a Planet VAT refund kiosk with your passport, boarding pass, tax invoices, and purchased goods. Ensure items are unused and bought within 90 days. Scan your documents at the kiosk and get approval from customs if required. After validation, choose your refund method—credit card or cash. Refunds are available only for tourists leaving the UAE. Arrive early to allow time for the process.
