Koh Tao is a sub-district (tambon) of Ko Pha-ngan district, not a province, so it has no Immigration Bureau, Land Office or Provincial Hall of its own -- see our separate Koh Tao immigration office guide for that side of things. What the island does have on-island: its own Police Station and Tourist Police unit, both in the south and centre of the island, and its Subdistrict Municipal Office in Chalok Baan Kao. Verified where possible against independent sources, with anything we could not confirm flagged rather than guessed.
Koh Tao has no Immigration Bureau or Provincial Land Office of its own. For 90-day reporting, visa extensions, TM30 and re-entry permits, see our Koh Tao immigration office guide. For land-title transfers, the relevant office sits on the Surat Thani mainland.
Primary and official sources are cited above. Government rules, fees and procedures in Thailand change over time and vary by office; always confirm current requirements with the relevant authority before relying on them. BAANLYY never takes paid placement in editorial content.
