Business Structures in Thailand

Start Your Business in Thailand with Confidence

Thailand is one of Southeast Asia’s most dynamic economies, offering a strategic location, strong infrastructure, competitive labor costs, and access to regional and global markets. Establishing a company here can be an excellent opportunity for foreign investors and entrepreneurs. However, the process of company registration in Thailand requires careful planning, compliance with local laws, and the right legal guidance.

At Skyinterlegal, we provide end-to-end assistance to ensure that your business is set up smoothly, legally, and efficiently.

Types of Business Structures in Thailand

For many businesses, the real question is not just how to register a company in Thailand, but which type of entity is legally and commercially appropriate. A structure that is ideal for one investor may be unsuitable for another. For example, a foreign group conducting market research may prefer a representative office, while an operating business that will invoice customers in Thailand may need a private limited company.

Thus, when establishing a business in Thailand, choosing the right legal entity is a critical first step. Each type of company or business structure has unique features, advantages, and restrictions under Thai law. Below are the most common options for foreign and Thai investors:

1. Private Limited Company (Co., Ltd.)

  • A Thai private limited company is the most common structure for doing business in Thailand. It combines limited liability for shareholders with the ability to engage in a wide range of business activities.
  • Key Features:
    • At least 2 individual shareholders at the time of incorporation. Once the company is incorporated, the shareholders may later be changed to juristic entities.
    • At least one director (can be foreign or Thai).
    • Shareholders’ liability is limited to the unpaid amount on their shares.
    • Subject to corporate income tax.
    • Must maintain proper accounting records and file annual financial statements.

Pros:

  • ✔ Limited liability for shareholders.
  • ✔ Credibility with banks, partners, and clients.
  • ✔ Can employ staff and sponsor work permits.
  • ✔ Widely accepted structure for foreign investors.

Cons:

  • ✘ May face restrictions under the Foreign Business Act (FBA) if majority foreign-owned, unless BOI promoted or granted a Foreign Business License.
  • ✘ Requires ongoing compliance, accounting, and audits.

2. Public Limited Company (PLC)

  • A Thai Public Limited Company is a structure that is designed for larger businesses seeking to raise capital from the public or list on the Stock Exchange of Thailand (SET).
  • Key Features:
    • At least 15 shareholders.
    • At least 5 directors.
    • Can offer shares to the public and be listed on the Stock Exchange of Thailand (SET).
    • Subject to more stringent reporting and governance requirements.

Pros:

  • ✔ Ability to raise significant capital from public investors.
  • ✔ Suitable for large-scale enterprises or those planning an IPO.
  • ✔ Enhanced reputation and market visibility.

Cons:

  • ✘ Complex compliance and governance obligations.
  • ✘ High costs for setup and ongoing operation.
  • ✘ Not suitable for small or medium businesses.

3. Branch Office

  • A branch office allows a foreign company to operate directly in Thailand under its existing brand and corporate structure abroad. This structure may be suitable where the foreign parent wants direct operational control and is comfortable carrying on business in Thailand through the parent company structure.
  • Key Features:
    • Considered part of the parent company (not a separate legal entity).
    • The parent company is liable for the branch’s obligations.
    • Subject to corporate income tax on locally derived income.
    • Requires approval from the Ministry of Commerce; in many cases, a Foreign Business License is necessary.

Pros:

  • ✔ Direct extension of a foreign company. 
  • ✔ Easier control by the parent company.
  • ✔ Can generate income in Thailand.

Cons:

  • ✘ Foreign Business License permission may still be required depending on the activity.
  • ✘ Limited in scope of business activities.
  • ✘ Higher compliance burden compared to representative offices.

4. Representative Office

  • A representative office is designed for foreign companies that want to establish a presence in Thailand for non-commercial activities, such as coordination, sourcing support, information gathering, market study, or quality control — but not ordinary revenue-generating trade.
  • Permitted activities may include:
    • Sourcing goods or services in Thailand.
    • Inspecting and controlling product quality.
    • Providing information to the parent company.
    • Reporting local business developments to headquarters.
    • Marketing and promotion (without sales).
  • Key Features:
    • Funded entirely by the parent company abroad.
    • Cannot earn revenue or engage in profit-making activities in Thailand.
    • Requires government approval and compliance with reporting rules.

Pros:

  • ✔ No taxation on income.
  • ✔ Simple presence for market research and liaison.
  • ✔ Lower compliance burden compared to branch offices.

Cons:

  • ✘ Cannot issue invoices or sign contracts on behalf of the parent company.
  • ✘ Entirely dependent on parent company funding.
  • ✘ Limited scope of activity.

5. BOI-Promoted Company

  • A BOI promotion is not a distinct corporate form; rather, companies in targeted industries (e.g., technology, manufacturing, renewable energy, and digital services) may apply for promotion from the Board of Investment (BOI) to obtain specific benefits.
  • Key Features:
    • May allow 100% foreign ownership, even in restricted sectors.
    • Special tax incentives, such as corporate income tax exemptions or reductions.
    • Exemption from import duties on machinery and raw materials.
    • Facilitation of work permits and visas for foreign staff.
    • Streamlined procedures for bringing in experts and investors.

Pros:

  • ✔ Strong government support.
  • ✔ Significant tax savings and investment incentives.
  • ✔ 100% foreign ownership permitted in many cases.
  • ✔ Easier employment of foreign specialists.

Cons:

  • ✘ Only available for specific industries aligned with Thailand’s development goals.
  • ✘ Application process can be complex.
  • ✘ Ongoing compliance and reporting requirements to maintain BOI privileges.

6. Partnership

Partnerships are less common for foreign investors compared to limited companies, but they can be suitable for certain small businesses or joint ventures with Thai nationals. There are two main types:

6.1 Ordinary Partnership

  • Requires at least two partners.
  • All partners have unlimited liability for the debts and obligations of the partnership.
  • The partnership itself may or may not be registered with the Ministry of Commerce.
    • If registered, the partnership becomes a separate legal entity.
    • If unregistered, it remains legally inseparable from its partners.

Pros:

  • ✔ Simple and inexpensive to set up.
  • ✔ Flexible structure for small businesses.

Cons:

  • ✘ Unlimited liability for all partners.
  • ✘ Less credibility than a limited company.

6.2 Limited Partnership

  • Requires at least two partners:
  • There are two types of partners in the entity:
    • General Partners: manage the business and have unlimited liability.
    • Limited Partners: invest capital, but their liability is limited to their contribution.
  • Must be registered with the Ministry of Commerce.

Pros:

  • ✔ Limited liability for limited partners.
  • ✔ Clear division between management and investors.

Cons:

  • ✘ General partners remain fully liable.
  • ✘ Less common for foreign investors compared to limited companies.

FAQs – Business Structures in Thailand

  • Private Limited Company: Best for most small-to-medium foreign businesses or joint ventures. This structure is the most popular for foreigners and Thai investors due to its business scope, allowing full commercial activities with limited liability on shareholders. 
  • Public Limited Company: Best for large-scale enterprises seeking public investment or listing.
  • Branch Office: Suitable for foreign companies wanting to directly trade or service in Thailand while maintaining parent company liability.
  • Representative Office: Best for companies doing sourcing, quality control, or market research without commercial activities.
  • BOI-Promoted Company: Ideal for foreign investors in high-potential industries seeking incentives and full foreign ownership. 
  • Ordinary Partnership: Suitable for small family businesses or ventures among trusted partners.
  • Limited Partnership: Suitable when investors want to contribute funds but avoid management and liability.

Note: Foreign investors rarely use partnerships due to liability risks and restrictions under the Foreign Business Act, but they can be appropriate for local joint ventures in certain industries.

The private limited company is the most commonly used structure. It offers limited liability, flexibility in operations, and eligibility to apply for licenses and permits.

In general, foreign ownership is restricted under the Foreign Business Act. Most of service businesses require a Thai majority shareholding (at least 51%).

  • The company obtains a Foreign Business License
  • The business qualifies under international treaties (e.g., US–Thailand Treaty of Amity)

Yes, capital requirements vary depending on the structure and ownership:

  • Foreign-owned companies typically require at least THB 2–3 million
  • Branch and representative offices usually require at least THB 3 million (remitted in phases)
  • BOI-promoted companies depend on project size and approval conditions

Yes, through branch office and representative office. However, both options have limitations, especially under the Foreign Business Act.

BOI promotion offers significant incentives, such as:

  • Tax holidays and reductions
  • Fewer restrictions on foreign ownership
  • Easier work permit and visa processes
  • Additional operational privileges

The best structure depends on several factors, including business activity, ownership preferences, tax planning, and long-term expansion goals.

Legal advice is strongly recommended to ensure compliance and optimal structuring.
