Koh Samui is the most developed of Thailand's family-friendly islands. It has an international airport, a full-service Bangkok Hospital, several international schools, and a large, established expat community. Bophut and Maenam on the north coast have a relaxed, village feel ideal for families. It costs more than Koh Phangan but offers meaningfully better infrastructure.

Action checklist
Concrete steps to make this move happen, in order.
Click any step to jump to that section ↓
- 1Apply for the DTV at a Thai embassy before travelling — required for any stay beyond the initial tourist visa period
- 2Contact international schools (ISS, ACE) directly and apply 2–4 months before your intended start date
- 3Arrange international health insurance that includes Bangkok Hospital Samui and emergency airlift to Bangkok
- 4Research neighbourhoods before arrival: Bophut and Maenam are the established family areas on the north coast
- 5Find accommodation through a local property agency or online search before arriving
- 6On arrival: ask your landlord to file the TM30 address form with immigration within 24 hours
- 7Open a Thai bank account at Bangkok Bank's Samui branch — requires a non-immigrant visa and rental contract
- 8Arrange transport: Koh Samui has no public transit — a reliable car or motorbike is essential for families
- 9Plan around the monsoon season (Oct–Dec): the east coast gets the worst weather; Bophut and Maenam are more sheltered
Family fit
Great for
- Families who want island living without sacrificing infrastructure
- Parents who need reliable international schooling on the island
- Frequent travellers (Samui has a regional airport with direct flights to Bangkok and beyond)
- Families transitioning from a higher-cost Asian city like Singapore or Hong Kong
Watch out for
- Higher cost than other Thai islands — housing prices have risen significantly since 2020
- Monsoon season (Oct–Dec) brings heavy rain and rough seas on parts of the island
- Traffic on the ring road can be busy; motorbike safety concerns apply
- Island isolation — for major specialist medical needs, Bangkok remains the destination

Visa options
Reviewed Jan 2026
Reviewed Jan 2026
Thailand has no EU-style permanent residency for foreigners. Short visits use a visa exemption on arrival or a consular tourist visa. For families staying long-term, the two practical routes are the DTV (Destination Thailand Visa, launched July 2024) — 180 days per entry on a 5-year multiple-entry visa — and the Thailand Privilege Visa (formerly Thailand Elite, rebranded October 2023) — a 5-to-20-year membership for families who want stable stays without periodic visa runs.
Tap the ? next to a term for a quick definition.
Tourist Visa / Visa Exemption
Good for an initial scouting trip. Not suitable for long-term stays or remote work.
DTV — Destination Thailand Visa
Thailand's long-stay visa for remote workers, launched July 2024. The best option for most expat families.
Thailand Privilege Visa (formerly Thailand Elite)
Government-backed long-stay residency operated by Thailand Privilege Card Co. (Ministry of Tourism and Sports). Rebranded from Thailand Elite in October 2023 with restructured tiers and prices.
Tourist Visa / Visa Exemption — what it allows
- Visa exemption on arrival: 54 countries (US, UK, EU, Canada, Australia, Japan, Singapore, UAE and others) currently get 30 days on arrival. This was 60 days from July 2024 until a Thai Cabinet decision on 19 May 2026 reduced it back to 30 — older travel advice may still cite the 60-day rule, so always verify on the Thai MFA site before booking.
- Extension at any Thai immigration office: +30 days for ~1,900 THB (about $55), at the immigration officer's discretion — not guaranteed, so plan around 30 days rather than counting on the extension.
- TR (Tourist Visa) applied at a Thai consulate before travelling: 60 days on arrival, plus one 30-day extension at immigration. This is the safer route if you want a longer scouting trip.
- Visa on Arrival (the paid 15-day visa) is available to only 4 nationalities (India, Belarus, Serbia, Azerbaijan) — most travellers cannot use this route.
- You cannot legally work on a tourist visa — this includes remote work for a foreign employer.
- Do not attempt to live in Thailand on back-to-back tourist entries — Thai immigration actively monitors this pattern and may deny re-entry.
- Best use: an initial 2–8 week scouting trip to view neighbourhoods, visit schools, and apply for a long-stay visa from back home or in a neighbouring country.
DTV (Destination Thailand Visa) — how to apply
- Stay: 180 days per entry, extendable once inside Thailand for another 180 days — up to ~360 days per entry cycle. Valid for multiple entries for 5 years from issue.
- Savings requirement: 500,000 THB (~$14,500 USD) in liquid personal savings, shown via 3–6 months of consistent bank statements. Stocks, crypto, retirement accounts, and business accounts are not accepted.
- Per dependent: most Thai embassies require another 500,000 THB (~$14,500) per dependent (spouse and each child). A family of three typically needs to show ~1,500,000 THB (~$43,000) total — confirm the exact figure with the consulate you apply through.
- Apply only from outside Thailand via the official e-Visa system (thaievisa.go.th) or at a Thai consulate — you cannot switch to a DTV from inside Thailand on a tourist entry.
- Cost: 10,000 THB (~$275–$500 depending on consulate) one-time fee for the full 5-year multi-entry visa. The 180-day in-Thailand extension costs another ~10,000 THB (~$275).
- No work permit included — you cannot legally work for a Thai employer or client. Remote work for foreign employers is the intended use.
- Tax residency warning: if you spend 180+ days in a calendar year in Thailand you become a Thai tax resident. Foreign income remitted into Thailand can be taxable since 1 January 2024 — talk to a Thai tax advisor before remitting large sums.
- After arrival, ask your landlord to file the TM30 (the landlord's address notification to immigration) within 24 hours, and file a 90-day report every 90 days (online at imm.immigration.go.th or in person at your local immigration office).
Thailand Privilege Visa — long-stay membership
- Five tiers (all one-time fees; no savings, income, or age requirements):
- Bronze — 650,000 THB (~$18,000–$20,000) for 5 years. The cheapest entry point; dependents not included.
- Gold — 900,000 THB (~$25,000–$28,000) for 5 years. Includes 20 service points/year; dependents not included.
- Platinum — 1,500,000 THB (~$42,000–$47,000) for 10 years. Dependents can be added for ~1,000,000 THB each.
- Diamond — 2,500,000 THB (~$70,000–$78,000) for 15 years. Dependents can be added for ~1,500,000 THB each.
- Reserve — 5,000,000 THB (~$140,000+) for 20 years. Invitation only.
- Not a work permit — but widely used by remote workers because there are no in-Thailand reporting periods to manage and no DTV-style savings paperwork.
- Best for families wanting maximum stability without periodic visa runs, savings proof, or consulate appointments. Bronze (~$3,700/year over 5 years) is roughly comparable to DTV renewal costs but with much less paperwork. For families needing dependents covered, Platinum or Diamond is usually the cheapest route per person.
Apply for the DTV at least 4–6 weeks before your travel date — Thai consulates in major cities can get backed up. Always verify your nationality's current visa-exemption length on the Thai Ministry of Foreign Affairs website before booking — Thailand has revised the rules multiple times in recent years.
Registration & 90-day report
Reviewed Jan 2026
Reviewed Jan 2026
- Thailand has no residency permit system for foreigners — your passport and current visa stamp are your documents on the island.
- Your landlord must file a TM30 form (address registration with immigration) within 24 hours of your arrival — ask them to confirm this was done.
- All visa holders must report their address to Thai immigration every 90 days. File online at imm.immigration.go.th or in person at the Koh Samui Immigration Office in Na Thon.
- Keep copies of all visa stamps, extension approvals, and 90-day receipts — officers ask for them during renewals.
- For banking, school enrolment, and admin, your passport and current visa stamp serve as your complete identification.
Do your 90-day report online at imm.immigration.go.th — saves a trip to the immigration office in Na Thon.
Banking
- Bangkok Bank and Kasikorn Bank (KBank) both have branches on Koh Samui — Bangkok Bank is generally more accommodating for foreign visa holders.
- To open an account you typically need: passport, non-immigrant visa (DTV or similar), and a rental contract as proof of local address.
- Use Wise or Revolut for receiving international income and converting to Thai Baht — bank wire fees are high.
- ATMs are widely available across the island; markets and smaller shops are still largely cash-based.
- Keep $14–$56 in cash on hand at all times for local transactions.
Bangkok Bank's branch on Koh Samui is the most established for expats — bring your passport, DTV visa, and rental contract.
Housing
Koh Samui is more expensive than Koh Phangan or Chiang Mai, but still very affordable by Western standards. A 3-bedroom villa near Bophut or Maenam rents for $700–$1,800/month. Long-term rentals (6–12 months) often come with significant discounts.
Where to search
These are the main platforms used to find long-term housing on Koh Samui.
Search 'Koh Samui' inside each platform to filter local listings.
Tip: spend 2–4 weeks in a short-term rental on the north coast (Bophut, Maenam) before committing — it is much easier to find a good deal once you are already on the island.
Typical monthly rents
- 1-bed condo or apartment, Bophut / Maenam: $330–$560 / month
- 2-bed house, north coast family areas: $560–$1,060 / month
- 3-bed pool villa, Bophut / Maenam / Plai Laem: $1,110–$2,080 / month
- Furnished short-stay apartment (bills included): $700–$1,530 / month
Best areas for families
What you need to rent
- Passport and current visa stamp
- 1–2 months security deposit in cash
- Monthly rent is usually paid by cash or Thai bank transfer
- Rental contracts are often bilingual (Thai and English) — read both versions before signing
- Ask your landlord to file the TM30 address registration form with immigration within 24 hours of your arrival — required by Thai law
Schools
Koh Samui has several international schools serving the expat community. Options are limited compared to a major city, but quality is solid and fees are very affordable.
Public system
Thai government schools on the island teach entirely in Thai. Not suitable for most expat children without extensive Thai language support.
International options
Two main accredited international schools serve the English-speaking expat community on Samui: ISS and ACE. Both cover Early Years through secondary. The schools are small by international standards, which some families see as a positive. For IB or British A-Level, families typically board their children in Bangkok or Chiang Mai.
Language notes
English is the language of instruction at both main international schools. Thai language classes are included in the curriculum. The expat community on the north coast communicates almost entirely in English.
Options are limited — contact schools early, as class sizes are small and spots fill quickly.
Education options
British / Cambridge curriculum international schools
Small selection of accredited schools serving the island's expat community. Limited capacity.
Local Thai private bilingual schools
Thai private schools with some English-medium instruction — significantly cheaper than international campuses at ~$2,000–$5,000/year. Curriculum follows the Thai national system. A viable option for younger children (under 8) whose parents want Thai language immersion alongside English, or for families on a budget who plan a multi-year stay.
Childcare
Koh Samui has more childcare options than Koh Phangan, with several licensed nurseries and a large pool of experienced Thai nannies.
Daycare & nurseries
- Private nurseries operate in the main expat areas on the north coast — a smaller selection than a mainland city but generally sufficient
- Typical fees: roughly $196–$504 / month; bilingual (English/Thai) programmes are available at most private nurseries
- Most nurseries accept children from 18 months old
- Visit in person — quality and English fluency of staff varies; community recommendations are your best guide
Nanny & au pair
- Full-time Thai nannies are widely available — typically $336–$588 / month for a live-in arrangement
- Part-time nannies: roughly $5–$7 / hr
- Many nannies have worked with expat families for years and have community references
- English fluency varies — build in a settling-in period and use vetted community referrals
Where to find childcare
- Search 'Samui Expats' on Google — most common starting point for nanny referrals on the island
- Search 'Samui Families' on Google — family-specific group with local recommendations
- Search 'Koh Samui International Community' on Google — broader community group
- Local property and relocation agencies sometimes maintain nanny referral lists
Healthcare
Reviewed Jan 2026
Reviewed Jan 2026
- Bangkok Hospital Koh Samui has a 24/7 emergency department, specialist clinics, and English-speaking doctors — the best medical facility on the island.
- For routine GP visits, children's appointments, and minor emergencies it is generally reliable and fast.
- For serious emergencies — complex surgery, major trauma, or difficult births — medical evacuation to Bangkok is typically required. Most expats arrange dedicated medevac (medical evacuation) insurance.
- Bangkok Hospital Samui can arrange emergency airlift to Bangkok through their partner network — the flight takes roughly 1 hour.
- Pharmacies are well-stocked across the island for everyday medications.
Arrange medical evacuation insurance that covers airlift to Bangkok — affordable and removes the biggest healthcare risk of island living.
Optional insurance option
Some families prefer to have private international medical coverage for the first period abroad. SafetyWing is one option to check if you want a flexible plan while relocating.
Check SafetyWingAlways confirm that any insurance you choose matches your visa, residency, and healthcare needs.
Safety
- Violent crime against residents is rare — the family-oriented north coast (Bophut, Maenam) is calm and low-crime.
- Road safety is the biggest daily risk: the ring road is busy, local driving standards vary, and motorbike accidents are common among expats. Use a car where possible, especially with children.
- Water safety matters for families with young children — some beaches have rip currents and seasonal jellyfish. Check local conditions before swimming.
- The Chaweng and Lamai areas are busier and noisier than the north coast — less suited to family daily life.
- Petty theft occurs in tourist-heavy spots — keep bags secure and avoid leaving valuables visible on the beach.
FAQ
Is Koh Samui good for families?
Good — especially for families who want beach life with more infrastructure than Koh Phangan. Better hospital, more school options, and a wider range of restaurants and services.
How much does a family typically need per month here?
Budget $3,000–$5,000/month for a family of four. Rent for a 3-bedroom villa runs $1,200–$2,500/month. International school fees are the largest single cost.
Is housing hard to find here?
Moderate. Popular areas like Bophut and Maenam have consistent availability, but quality villas move quickly. Start searching before you arrive rather than on landing.
Do children need international school here, or can local schools work?
International school is required. Thai government schools teach entirely in Thai and are not suitable for expat children. There are a handful of English-language international schools on the island — check availability and capacity before committing to a move.
Is healthcare easy to access as a newcomer?
For most day-to-day needs, yes — Bangkok Hospital Koh Samui has 24/7 emergency care and English-speaking staff. For complex surgery or specialist cases, Bangkok is the right destination. International health insurance with medical evacuation coverage is strongly recommended.
Do you need a car on Koh Samui?
Yes. There is no public transport on the island. A car is the practical choice for families — essential for school runs, grocery shopping, and daily errands.
How difficult is the paperwork and bureaucracy after moving?
Simple. Same as all Thai destinations: no residency system, no local ID needed. Keep your visa current, complete 90-day address reports to Thai immigration, and ensure your landlord files the TM30 (address registration form) within 24 hours of your arrival.
What usually surprises families after arrival?
How expensive it feels compared to Chiang Mai or the mainland. Samui's popularity with tourists has pushed housing costs up significantly — families expecting typical Thai prices are often caught off guard. Budget accordingly.
