The Tourism and Sports Ministry has settled on a 450 baht per-trip levy on foreign tourists (TTF, "ground-stepping fee"). Phase one covers air arrivals only; land and sea crossings follow one year later. It still needs a 30-day public consultation, a National Tourism Policy Committee meeting, Cabinet approval and Royal Gazette publication, then starts 180 days after gazetting, at the earliest around April 2027. The levy is up from the 300 baht air / 150 baht land rate Cabinet approved in February 2023, and the ministry has spent 3-4 years on it without success. For a tourism-facing SME, this is a future cost to plan for, not a change to make now. Watch for the Gazette notice.
