Buying a Business in Thailand as a Foreigner

This is the complete 2026 playbook. From the macro market to the micro detail of licence transferability, every chapter is built from real deals and current regulations. Start at the beginning or jump to the section you need — the sidebar will keep you oriented.

1. Market Overview 2026

Thailand enters 2026 with a stable post‑election government, tourism arrivals back above 35 million annually, and the Board of Investment (BOI) reporting a 22% year‑on‑year increase in foreign project applications. Private equity and high‑net‑worth individuals from Europe, the US, China, and the Middle East are deploying capital into Thai SMEs, particularly in F&B, wellness, e‑commerce, and boutique hospitality. The Thai baht has stabilised in the 34–35 THB/USD range, making acquisitions more predictable for foreign buyers. Combined with the May 2026 FBA amendment removing eight service categories from List 3, the market is the most accessible it has been for foreign investors in over a decade.

2. Foreign Ownership Restrictions (FBA 101)

The Foreign Business Act (FBA) divides economic activities into three lists:

• List 1: Strictly prohibited for foreigners (e.g., media, farming, land trading).
• List 2: Activities related to national security or culture (e.g., weapons, antiques) — Cabinet approval required; minimum 40% Thai equity.
• List 3: Activities where Thai nationals are not yet competitive (e.g., restaurants, retail, legal services, tour guiding) — a Foreign Business Licence (FBL) is required unless a BOI promotion, Treaty of Amity, or the 2026 exemption applies.

The May 2026 Cabinet resolution removed eight service categories from List 3, allowing 100% foreign ownership without an FBL, BOI, or treaty. The implementing regulation is expected to be gazetted by Q3 2026. Until then, confirm your target sector with a Thai corporate lawyer.

3. Legal Ownership Structures

4. Nominee Risk & Compliance

The Department of Business Development (DBD) investigated over 820 companies in 2024–2025 for nominee shareholder violations. A nominee arrangement — where Thai shareholders hold shares on behalf of a foreigner to circumvent the 49% cap — is illegal under the Foreign Business Act and can result in the company being dissolved, fines, and criminal liability. Safe alternatives include the structures in Chapter 3. If a Thai‑majority structure is your only route, ensure genuine Thai partners with real financial contributions and a transparent shareholders' agreement drafted by a reputable law firm.

5. Investment Capital Requirements

• Non‑B visa work permit: minimum registered capital of 2 million THB per foreigner (approximately USD 55,000).
• BOI promotion: minimum investment 1–3 million THB depending on category.
• SMART Visa (startup): 500,000 THB minimum investment.
• LTR Wealthy Investor: personal income of 80,000 USD/year or assets of 1 million USD (including property and investments).

The purchase price of the business is on top of these capital requirements. Most deals in the 5–50 million THB range are funded by a combination of offshore transfers and local equity.

6. Visa & Work Permit Pathways

7. Sector-by-Sector Pricing Guide

Total acquisition cost = (EBITDA × multiple) + key money + refundable lease deposit + inventory. The next two chapters cover lease and licence costs in detail.

8. Lease & Property Framework

Commercial leases in Thailand are typically 3‑year terms, often renewable. The key points for a foreign buyer:

• Assignment clause: The lease must explicitly permit assignment to a new company or shareholder. “Landlord consent required” without a clear right to assign is a deal‑breaker.
• Landlord consent: Obtain written consent from the landlord before signing the SPA. A verbal promise is worthless.
• Key money: A one‑off payment to the landlord at lease signing, often 3–12 months' rent. This is additional to the purchase price.
• Lease registration: Leases over 3 years must be registered at the Land Office to be enforceable.

9. Licence & Permit Transferability

Not all licences transfer automatically in a share sale. Key examples:

Always confirm the transferability of every licence with the issuing authority during due diligence. An asset sale may be necessary if key licences cannot be transferred via a share deal.

10. Tax & Revenue Department Standing

A clean tax record is non‑negotiable. During due diligence, verify:

• VAT registration and filing history for the trailing 12 months.
• Corporate income tax (CIT) returns for the last 3 years.
• Withholding tax compliance on salaries, supplier payments, and cross‑border remittances.
• Tax clearance letter: Request a “letter of tax compliance” from the Revenue Department before closing. Any outstanding assessment becomes your liability.

11. Financial Due Diligence

• 3 years of audited or management accounts — bank statement reconciliation is essential.
• EBITDA recast: document every add‑back (owner salary, personal expenses, non‑recurring items).
• Cash vs. declared revenue gap — common in cash‑heavy F&B businesses.
• Related‑party transactions: rent paid to owner's property company, management fees.
• Outstanding creditors, supplier deposits, and employee severance accruals.

12. Legal Due Diligence

• DBD register: verify current shareholder list and check for any pledge or encumbrance on shares.
• Articles of association: confirm no transfer restrictions or pre‑emption rights that could block the deal.
• Litigation check: civil, criminal, labour disputes.
• Nominee shareholder flags: Thai shareholder profiles inconsistent with the business scale.

13. Operational Due Diligence

• Employment contracts: severance obligations, non‑compete, and social security compliance.
• Key supplier and customer agreements: are they with the company or with named individuals?
• Inventory valuation and condition.
• IT systems, point‑of‑sale, and intellectual property (trademarks, domain names).

14. Key-Man Risk & Transition Planning

In Thailand, the owner is often the brand. Quantify key‑man dependency on a spectrum: revenue concentration, operational reliance, and brand association. Mitigation tools include:

15. The Letter of Intent (LOI)

The LOI is where you lock in key commercial terms before exclusivity is granted. Negotiate here:

• Purchase price and payment structure (cash at close, deferred, earnout).
• Exclusivity period (30–45 days standard) with milestone‑based extension.
• Conditions precedent: lease assignment, BOI endorsement, licence transfer, landlord consent.
• Due diligence access timeline and data room SLA.
• Break fee (on deals above 30M THB) — protects your DD costs if the seller withdraws.

Your leverage is highest before exclusivity; renegotiating later is significantly harder.

16. Share vs. Asset Sale Mechanics

17. The Acquisition Process Timeline

1. First enquiry & matching — 1–2 weeks
2. NDA execution & IM release — 1 week
3. Site visit & initial LOI — 2–4 weeks
4. Due diligence — 4–8 weeks
5. SPA negotiation & signing — 2–4 weeks
6. Conditions precedent fulfilment — 2–6 weeks
7. Closing & payment — 1 day

18. Financing the Deal

Most foreign acquisitions are funded by offshore capital — personal savings, family office, or private equity. Practical considerations:

• Offshore transfer: funds must be remitted in foreign currency and converted to THB. Keep the Foreign Exchange Transaction Form (FETF) as proof for future repatriation.
• Local bank accounts: a Thai corporate account can be opened once the company is registered; a personal account is available with a long‑term visa.
• Seller financing: common in Thailand — 10–30% of the price deferred over 12–24 months, often with interest or earnout provisions.
• Equity partnerships: bringing in a Thai minority partner (genuine) can satisfy FBA requirements and provide local market access.

19. Post‑Closing Integration

After the SPA is signed and funds transferred, the following must be completed within 30 days:

• Update DBD registration (new shareholder list, directors).
• Change bank account signatories.
• Transfer VAT registration and notify the Revenue Department.
• Notify Social Security Office of any change in employer status.
• Update work permits and visa extensions for any foreign staff.

20. Ongoing Compliance & Reporting

• Annual audit: required for all Thai limited companies; must be filed with the DBD and Revenue Department.
• Board meetings: at least one per year; minutes must be recorded.
• Social Security & VAT: monthly/quarterly filings.
• Visa renewal: Non‑B and work permit must be renewed annually; LTR and SMART visas have their own reporting cycles.

21. Common Deal Killers (and How to Avoid Them)

• Lease assignment rejected by landlord — always get written consent before SPA.
• Nominee shareholder flags in DBD audit — resolve structure before offering.
• Tax clearance letter reveals hidden liabilities — request early and address.
• Key licence is personal and non‑transferable — switch to asset sale or reapply.
• Key‑man departs with no transition — lock in retention and transition terms at LOI stage.

22. Working with Local Advisors

Your core team should include:

• Thai corporate lawyer: bilingual, experienced in foreign business acquisitions and BOI/treaty applications.
• Accountant/auditor: local firm to recast financials and handle post‑closing compliance.
• Buy‑side M&A advisor: vets deals, structures the process, and provides a buffer between you and the seller.

Verify credentials through the Lawyers Council of Thailand, the Federation of Accounting Professions, and client references. Fee structures: lawyers typically bill hourly (3,000–8,000 THB/hour); advisors may charge a retainer + success fee.

23. Case Studies (Anonymised)

24. Off‑Market Opportunities & Deal Flow

Many of the best businesses never appear on public listing platforms. Sellers prefer confidentiality — they don't want staff, customers, or competitors to know the business is for sale. Off‑market mandates are shared only with qualified, NDA‑signed buyers. We maintain a curated pipeline of off‑market opportunities across F&B, wellness, e‑commerce, and hospitality. Access is granted after an initial buyer consultation.
