Green Tax is payable for each day the tourist spends at a tourist establishment or vessel. This means that each 24-hour block between check-in time and check-out time will be considered as 1 taxable day. If the tourist spends 12 hours or more at the establishmen/vessel during that 24-hour block, the tourist must pay Green Tax for the block at the rate applicable for the respective tourist establishment type, on the date on which the 12-hour duration is completed. If the stay is less than 12 hours, Green Tax is not payable for that 24-hour block.
