ExpatWhy editorial.
Koh Samui is Thailand's third-largest island in the Gulf, international airport directly on the island, an established expat retiree community, and a structurally different climate pattern from western Thai coasts.
editorial
The case & the friction.
The case is the package: a working tropical island of about 70k residents + significant tourism inflow, the Big Buddha Wat Phra Yai, Lamai and Chaweng beaches, and the surrounding Ang Thong Marine National Park. The Samui International Airport handles direct flights from Bangkok, Singapore, Kuala Lumpur, Hong Kong. A 1-bed in Chaweng, Lamai, or Bophut runs ฿20,000-40,000/month ($560-1,120) furnished.
Same Thailand visa picture as elsewhere, DTV Destination Thailand Visa (2024), Elite Visa, Long-Term Resident Visa, 60-day visa exemption. Thai essential past expat contexts; English widely usable in tourist districts.
The friction is the Gulf-of-Thailand reversed monsoon, the western Thai coast's dry season is Samui's wet season (October-December brings the heaviest rain), and the western coast's wet season is Samui's dry. The island gets less rain overall than Phuket. Tourism load varies sharply by season; rents 30-50% higher during high season Dec-Feb. Air clean. No quake exposure; mild tropical storm exposure (the 2017 Tropical Storm Pabuk hit Samui directly, but storms are rare).

No tax carve-out for nomads. The DTV is a visa, not a tax regime: it changes neither residency (180 days or more in a calendar year) nor the remittance rule below.
tax treaty with
Since 1 January 2024 (Revenue Department orders P.161/2566 and P.162/2566), foreign-source income that a tax resident earned from 2024 onward is taxable when it is brought into Thailand, even in a later year; delaying the transfer no longer avoids it. Income earned before 2024, or in a year you were not resident, stays outside Thai tax when remitted. Work you physically do in Thailand is Thai-source wherever it is paid. Treaties, exemptions and your own facts change the outcome, confirm with a Thai tax adviser before relying on this.
