Thai company property purchase Koh Samui has become a popular route for overseas investors seeking flexibility, tax efficiency, and the ability to own multiple assets under one legal entity. In 2026, foreign buyers can enjoy potential tax savings of up to 15% and greater protection of personal assets, while still complying with Thai land‑ownership laws. This guide walks you through the three main structures—Thai Limited Company, BOI‑approved Company, and direct personal ownership—highlighting their benefits, drawbacks, and the steps required to secure your dream villa.
1. Why Consider a Company Structure?
1.1 Asset Protection
Using a corporate vehicle isolates the villa from personal liabilities such as business debts or legal claims, offering a layer of security that direct ownership cannot provide.
1.2 Flexibility for Multiple Properties
A single company can own several villas across Koh Samui, simplifying management, accounting, and eventual sale of assets.
1.3 Tax Planning Opportunities
Companies can deduct legitimate expenses (maintenance, staff, marketing) from taxable income, potentially lowering the effective tax rate compared with personal ownership.
2. Thai Limited Company (Thai Ltd) – The Standard Choice
2.1 How It Works
A Thai Ltd must have at least three shareholders, with a minimum of 51% Thai‑national ownership. Foreign shareholders hold the remaining 49% through shareholding, not land ownership.
2.2 Pros
- Clear legal framework: Well‑established, recognised by banks for financing.
- Ability to apply for a loan: Thai banks regularly lend to Thai Ltds, often up to 70% of the property value.
- Simplified transfer of ownership: Shares can be transferred without re‑registering the land title.
2.3 Cons
- Shareholding cap: The 49% foreign quota limits direct control.
- Annual compliance: Requires audited accounts, tax filings, and a minimum paid‑up capital of THB 2,000,000 (approx. $59,000).
- Potential withholding tax: Dividends paid to foreign shareholders may be subject to a 10% withholding tax.
3. BOI‑Approved Company – For Business‑Oriented Investors
3.1 What Is BOI?
The Board of Investment (BOI) offers incentives to companies engaged in promoted activities, such as tourism services, hospitality, or property development.
3.2 Pros
- Full foreign ownership: BOI permits 100% foreign shareholding, removing the 49% cap.
- Tax incentives: Corporate income tax exemption for up to 8 years, and 100% exemption on import duties for equipment.
- Land lease rights: BOI companies can lease land for up to 30 years, renewable for another 30 years, suitable for villa projects.
3.3 Cons
- Eligibility criteria: Must meet BOI’s promoted activity list and investment thresholds (typically THB 10,000,000 / $294,000).
- Longer setup time: Application and approval can take 2–3 months.
- Lease, not freehold: Land is leased, not owned outright, which may affect resale perception.
4. Direct Personal Ownership (Freehold Chanote)
4.1 Overview
Foreigners cannot own land freehold in Thailand, but can own condominium units on the 49% foreign quota basis. For villas, the only route is through a Thai‑owned company.
4.2 When It Still Makes Sense
- Short‑term holiday home: If you plan to stay < 6 months per year and do not need asset protection.
- Simple transactions: No corporate set‑up, lower ongoing compliance costs.
5. Cost Comparison – Thai Ltd vs BOI vs Personal Ownership
| Structure | Set‑up Costs (Legal & Registration) | Minimum Paid‑up Capital | Annual Compliance Cost | Typical Loan Availability | Tax Rate on Rental Income |
|---|---|---|---|---|---|
| Thai Ltd | THB 150,000 (approx. $4,400) | THB 2,000,000 (approx. $59,000) | THB 30,000–50,000 (approx. $880–1,470) | Up to 70% LTV | 15% corporate tax (plus 10% withholding on dividends) |
| BOI Company | THB 250,000 (approx. $7,350) | THB 10,000,000 (approx. $294,000) | THB 40,000–70,000 (approx. $1,180–2,060) | Up to 80% LTV (BOI‑backed) | 0% corporate tax for incentive period |
| Personal (Condos) | THB 80,000 (approx. $2,350) | N/A | N/A | Up to 60% LTV | 15% personal income tax |
All figures are indicative ranges for 2026 and assume exchange rate 1 USD = 34 THB.
6. Step‑by‑Step: Setting Up a Thai Ltd for Villa Purchase
6.1 Choose a Company Name & Reserve It
Submit three preferred names to the Department of Business Development (DBD). Reservation fee: THB 1,000.
6.2 Draft the Memorandum & Articles of Association
Include the business purpose (e.g., “investment in residential real estate”). A Thai lawyer typically charges THB 30,000–45,000.
6.3 Register the Company
Submit documents to the DBD, pay registration fee (0.5% of registered capital, minimum THB 5,000). Receive a corporate tax ID.
6.4 Open a Corporate Bank Account
Most major Thai banks require a board resolution and ID copies of all shareholders.
6.5 Transfer Funds for Paid‑up Capital
Deposit the agreed capital; the bank issues a confirmation letter for the Land Department.
6.6 Acquire the Villa
- Conduct due‑due diligence (title deed, land use, zoning). See our “/guides/due-diligence-checklist/” for details.
- Sign the sale‑and‑purchase agreement in the company’s name.
- Register the transfer at the Land Department (fees ≈ 2% of purchase price).
7. Managing the Villa Through the Company
7.1 Accounting & Tax Filing
Maintain proper books; hire a certified accountant to file annual corporate tax returns by March 31.
7.2 Rental Income Distribution
After deducting allowable expenses, profits can be distributed as dividends (subject to 10% withholding tax) or reinvested to grow the portfolio.
7.3 Exit Strategy
You can sell the villa and retain the company, or simply transfer shares to a new buyer. Share transfer avoids land‑title re‑registration, saving time and cost.
8. Choosing the Right Structure for Your Goals
| Goal | Recommended Structure |
|---|---|
| Asset protection & multiple villas | Thai Ltd (or BOI if you meet criteria) |
| Maximum tax incentives & 100% foreign control | BOI‑approved company |
| Simple, low‑maintenance holiday home | Direct personal ownership of a condo unit |
Consult a qualified Thai property lawyer to match your investment profile with the optimal structure.
9. Frequently Asked Questions
Q: Can I convert a Thai Ltd into a BOI company later? A: Yes, but you must apply for BOI promotion afresh and meet the activity and capital requirements.
Q: What happens if I sell the villa at a profit? A: Capital gains are taxed at the corporate rate (15%) for a Thai Ltd; BOI companies may benefit from tax exemption during the incentive period.
Q: Are there restrictions on foreign shareholders being directors? A: No. Foreigners can serve as directors, but at least one director must be a Thai resident for official correspondence.
