A new tourism tax is set to come into force in Thailand. Travellers will be charged 300 baht or S$11.80. Thailand is not the first country to impose this tax. Bali has imposed something similar and Japan is considering increasing its tourism tax to fund initiatives that address overtourism. Andrea Heng and Hairianto Diman assess the effectiveness of such tax and the impact it has on the tourism figures with Gary Bowerman, director, Check-in Asia and Asia Travel & Tourism Analyst
