The government plans to raise the foreign tourist fee from the proposed 300 baht to 450 baht (about US$15). Collection could start as early as April 2027, after the regulation is published in the Royal Gazette and enacted within 180 days. Airfare collection would start first; land and sea arrivals would follow about a year later. Hotels, tour operators and tourism-linked shops should factor a higher cost of travel for foreign guests into 2027 pricing and planning. The ministry says the fee should not hurt tourism sentiment. The timeline is still provisional.
