The Revenue Department has published a draft Departure Tax Act: 1,000 baht per trip for air travellers leaving Thailand, Thai and foreign alike, capped at 5,000 baht per trip, with land and sea travel exempt. Airlines or ticket agents would collect it with the fare. Penalties for evasion reach twice the tax plus 1.5% monthly surcharge. The online hearing runs to 29 October at law.go.th, and the article notes it is unclear if it will be introduced. For tour and travel businesses, this could raise fares and affect outbound and inbound demand; it is not yet law, so plan for it as a possibility rather than a cost.
