Ownership Structures for Foreign Investors in Thailand | BOI, FBL & More

Thailand remains one of Southeast Asia’s most attractive destinations for foreign investment, particularly in real estate, hospitality, manufacturing, and services. However, foreign investors cannot freely own businesses or land in Thailand without proper legal structuring.

Choosing the correct ownership structure is one of the most critical decisions when investing in Thailand. The structure determines:

  • Whether land ownership is permitted
  • Whether a Foreign Business License (FBL) is required
  • Whether BOI promotion is available
  • Long-term operational control and exit flexibility

This article provides a practical legal overview of ownership structures for foreign investors in Thailand, focusing on what is permitted, what is restricted, and how foreign investors typically structure their investments.

Why Ownership Structure Matters for Foreign Investors

Thai law distinguishes clearly between Thai-owned and foreign-owned businesses. An improper structure can result in:

  • Inability to operate legally
  • Rejection of licenses
  • Forced restructuring or divestment
  • Criminal and administrative penalties

For this reason, ownership structuring should be addressed before signing any acquisition or investment agreement.

Common Ownership Structures for Foreign Investors in Thailand

1. BOI-Promoted Company (Most Investor-Friendly Structure)

Projects promoted by the Board of Investment of Thailand (BOI) enjoy the most flexibility for foreign ownership.

Key features:

  • 100% foreign shareholding permitted
  • Possible approval for foreign land ownership
  • No requirement for a Foreign Business License
  • Ability to employ expatriates
  • Tax and customs incentives (subject to conditions)

Common uses:

  • Hotels and resorts
  • Manufacturing and technology
  • Large-scale or policy-supported investments

BOI promotion is not automatic and depends on project size, location, and economic contribution.

2. Thai Limited Company (Majority Thai Shareholding)

A Thai limited company is one of the most commonly used structures when BOI promotion is not available.

Legal requirements:

  • At least 51% Thai shareholding
  • Foreign ownership limited to 49%
  • Land ownership permitted if the company is genuinely Thai

Control mechanisms often used:

  • Preference shares
  • Different voting rights
  • Reserved matters in the articles of association

This structure is widely used but must be carefully designed to avoid nominee-shareholder risks.

3. Foreign Business License (FBL)

Under the Foreign Business Act, a company that is majority foreign-owned may be prohibited from engaging in certain business activities unless it obtains a Foreign Business License (FBL).

Key points:

  • Approval is discretionary
  • Authorities assess necessity and economic benefit
  • Processing time can be lengthy
  • Not all businesses are eligible

An FBL allows legal operation but does not override land ownership restrictions.

4. Leasehold Ownership Structure

Foreign investors may control property or business premises through long-term leasehold arrangements.

Key characteristics:

  • Maximum initial term of 30 years
  • Renewal subject to contract
  • Land ownership remains Thai

Leasehold structures are commonly used for:

  • Hotels and resorts
  • Commercial real estate
  • Industrial projects without BOI promotion

Strong legal drafting is essential to protect renewal and transfer rights.

5. U.S.–Thailand Treaty of Amity

U.S. investors may rely on the U.S.–Thailand Treaty of Amity, which allows American companies to operate businesses in Thailand on a similar basis to Thai nationals.

Benefits:

  • Majority or full foreign ownership allowed
  • Exemption from certain Foreign Business Act restrictions

Limitations:

  • Land ownership restrictions still apply
  • Some business sectors remain excluded

6. Lease of Business or Operating Company

In some cases, investors choose to lease a business or operating company rather than acquiring shares or land.

This structure can:

  • Reduce regulatory exposure
  • Allow operational control
  • Limit capital investment

However, it requires strong contractual safeguards and careful risk allocation.

Which Ownership Structure Is Right?

There is no single “best” structure. The correct approach depends on:

  • Investor nationality
  • Business sector
  • Whether land ownership is required
  • Investment scale and duration
  • Exit strategy

Early legal advice is critical to avoid costly restructuring later.

Conclusion: Structuring Foreign Investment in Thailand

Ownership structuring is the foundation of any successful foreign investment in Thailand. Whether through BOI promotion, a Thai limited company, an FBL, or leasehold arrangements, each option carries different legal, tax, and operational implications.

Foreign investors should always consult experienced legal and tax professionals before committing to an investment.
