Setting up in Thailand: how foreign companies should choose between a Thai limited company, branch office and representative office

Choosing the right entity is one of the first decisions foreign companies make when expanding into Thailand. Learn how Thailand’s primary business structures compare and what factors should guide your decision.

Thailand continues to attract foreign direct investment, making it an increasingly attractive destination for international expansion.

In 2025, Thailand’s Ministry of Commerce approved 1,078 foreign business operators, with total investment reaching THB 324.1 billion—a five-year high. Nearly half of those approvals came through Thailand’s Board of Investment (BOI).

As more international businesses establish operations in the country, one of the first decisions they face is how to structure their presence.

In practice, that usually means choosing between a Thai limited company, branch office and representative office.

For most foreign companies, a Thai limited company is the preferred long-term structure. A branch office can work well for businesses operating directly through the foreign parent. A representative office is designed for non-commercial activities such as market research and liaison services.

Choosing the right entity, however, isn’t simply a legal decision.

The right structure depends on your business activities, ownership requirements, hiring plans and long-term expansion strategy. BOI eligibility, Foreign Business Act (FBA) restrictions and workforce planning often influence the decision just as much as the entity itself.

This guide compares Thailand’s primary business structures, explains where each one fits and outlines the regulatory considerations that can shape a successful market entry.

Key takeaways

• A Thai limited company is the preferred structure for most foreign companies establishing long-term operations.
• Branch offices can conduct commercial activities but remain legally part of the foreign parent company.
• Representative offices support non-commercial activities only and cannot generate revenue.
• BOI promotion and the FBA often have a greater impact on entity selection than the legal structure itself.
• Companies that need employees before establishing an entity may benefit from using an Employer of Record (EOR).

Choosing the right structure starts with the right questions

Many companies begin their Thailand expansion by asking a straightforward question: Should we establish a Thai limited company, a branch office or a representative office?

It’s an important question, but not the first one that should be answered.

Four questions to answer before choosing an entity

Before selecting a business structure, organizations should first consider:

• Will the business conduct commercial activities in Thailand?
• Is the proposed activity eligible for BOI promotion?
• Will the FBA restrict foreign ownership?
• How quickly does the company need to hire employees and begin operating?

The answers often narrow your options before entity registration even begins.

For example, a representative office cannot generate revenue regardless of ownership.

Likewise, a company that qualifies for BOI promotion may be eligible for up to 100% foreign ownership, while another operating in a restricted sector may require a Foreign Business License (FBL).

Choosing the right entity, therefore, isn’t simply about comparing three legal structures.

It’s about selecting the operating model that best supports your commercial objectives today while creating flexibility for future growth.

Comparing Thailand’s business structures

Before exploring each option in more detail, here’s how Thailand’s three primary business structures compare across the areas that matter most to foreign investors.

Thai limited company vs. branch office vs. representative office

Three observations stand out.

• A representative office is designed exclusively for non-commercial activities. It cannot sell products or services, issue invoices or sign commercial contracts. However, it is legally permitted to directly hire local and foreign staff specifically to carry out its permitted non-commercial functions, such as market research, product inspections, and sourcing.
• Branch offices are strictly ineligible for BOI promotions. If an expanding business wants to utilize BOI tax incentives, investment protections and 100% foreign ownership benefits, it cannot use a branch structure. The project must instead be incorporated as a local Thai Private Limited Company.
• Both a Thai limited company and branch office support commercial operations, but they create very different structures. For most organizations planning a long-term presence in Thailand, the real decision is whether a Thai limited company or branch office best aligns with the company’s operating model and long-term expansion strategy.

Thai limited company: The default route for long-term operations

For most foreign companies, a Thai limited company is the preferred structure for establishing a long-term presence in Thailand.

A Thai limited company is a separate legal entity under Thai law. It can sign contracts, issue invoices, own assets and hire employees directly.

Unlike a branch office, a Thai limited company creates a legal separation between the Thailand business and the foreign parent. This helps limit the parent’s exposure to operational liabilities.

For organizations planning to build a local team, serve customers in Thailand and grow over time, this structure provides the greatest flexibility.

When a Thai limited company is the right choice

A Thai limited company is often the best option when:

• The business needs to invoice Thai customers and generate local revenue.
• Employees will be hired directly in Thailand.
• Local contracts need to be signed.
• The company plans to establish a long-term commercial presence.
• The business qualifies for BOI promotion or operates outside sectors restricted under the FBA.

Compliance considerations before registering

Choosing a Thai limited company is only part of the decision.

Ownership structure, regulatory requirements and future business plans should all be considered before incorporation.

Before registering, organizations should confirm:

• Whether the proposed business activity appears on the FBA restricted list.
• Whether the business qualifies for BOI promotion.
• Whether the ownership structure complies with Thailand’s foreign ownership rules.
• Whether future fundraising, local investors or exit plans should influence the company’s shareholding structure.

Addressing these questions early helps reduce compliance risk and avoids costly restructuring as the business grows.

Branch office: Best suited to parent-controlled operations

A branch office allows a foreign company to establish a commercial presence in Thailand without creating a separate legal entity.

Instead, it operates as an extension of the foreign parent company. Contracts are entered into by the parent, and the parent remains legally responsible for the branch’s activities.

This structure can work well for organizations that want to maintain centralized control while operating directly through the foreign parent.

When a branch office makes sense

A branch office may be appropriate when:

• The foreign parent wants to retain direct operational control.
• Commercial activities will be conducted in the parent’s name.
• There are no plans to introduce local shareholders or outside investors.
• The Thailand operation will remain closely integrated with the overseas business.

Where a branch office falls short

Although a branch office can generate revenue, it has several important limitations.

Unlike a Thai limited company, it is not eligible for BOI promotion. FBA restrictions still apply, and certain activities may require an FBL.

A branch office can also make it more difficult to raise local capital, bring in equity partners or separate the Thailand business from the foreign parent in the future.

For companies planning long-term growth, a Thai limited company often provides greater flexibility with similar compliance obligations.

Representative office: Useful for research, not for selling

A representative office is the most limited business structure available to foreign companies in Thailand.

Rather than conducting commercial activities, its role is to support the foreign parent through market research, supplier coordination and other liaison activities.

Because it cannot generate revenue, a representative office is best suited to organizations evaluating the Thai market before making a larger investment.

What a representative office can do

A representative office can:

• Conduct market research and feasibility studies.
• Source goods or services on behalf of the foreign parent.
• Perform quality control and inspection activities.
• Coordinate with suppliers and customers.
• Promote the parent company’s products or services without selling them directly.

What a representative office cannot do

A representative office cannot:

• Issue invoices or receive payments from customers.
• Sign revenue-generating contracts.
• Import or export goods independently.
• Hire employees directly.
• Conduct commercial business in Thailand.

While a representative office can provide a low-commitment way to explore the Thai market, its limitations become apparent once a business is ready to generate revenue or build a local workforce.

At that point, organizations typically transition to a Thai limited company or consider an Employer of Record (EOR) while preparing for entity establishment.

Understanding BOI promotion and the FBA

Choosing the right business structure is only one part of entering the Thai market.

Before registering an entity, foreign companies should also understand how the BOI and the FBA may affect ownership, licensing requirements and long-term expansion plans.

For many organizations, these regulatory considerations influence the optimal market entry strategy more than the entity itself.

How BOI promotion supports foreign investment

Thailand’s BOI promotes investment in industries that support the country’s long-term economic development.

Companies approved for BOI promotion may qualify for incentives such as:

• Up to 100% foreign ownership in eligible sectors.
• Corporate income tax exemptions or reductions.
• Import duty exemptions on qualifying machinery and raw materials.
• Simplified work permit and visa processes for foreign employees.

BOI promotion is not available for every industry. Eligibility depends on the nature of the business activity rather than the entity structure alone.

For qualifying companies, BOI approval can significantly simplify market entry while reducing operational costs.

How the FBA affects foreign ownership

The FBA regulates the types of business activities foreign-owned companies may undertake in Thailand.

Certain activities are restricted or require an FBL before commercial operations can begin.

Because these restrictions depend on the proposed business activity, companies should assess FBA implications before selecting an entity structure or ownership model.

Understanding both BOI opportunities and FBA restrictions early helps organizations avoid unnecessary delays and build an expansion strategy that aligns with Thailand’s regulatory framework.

Hiring employees before establishing an entity

Entity registration isn’t always the fastest way to begin operating in a new market.

Many companies want to hire local employees, launch projects or test the market before completing the incorporation process.

Using an EOR during market entry

An EOR enables businesses to legally hire employees in Thailand without first establishing a local entity.

The EOR provider becomes the legal employer, managing payroll, employment contracts, tax withholding and statutory compliance. The client company directs employees’ day-to-day work.

For many organizations, an EOR provides a practical way to:

• Hire employees quickly.
• Test the market before making a long-term investment.
• Begin operations while entity registration is underway.
• Reduce administrative complexity during early expansion.

As operations grow, companies can transition employees from the EOR to their own Thailand entity when the timing is right.

Which structure is right for your business?

There is no single “best” entity for every foreign company entering Thailand.

The right choice depends on your commercial objectives, hiring plans, ownership requirements and long-term expansion strategy.

Choosing the right market entry strategy

The most effective market entry strategies consider more than legal structure alone.

Companies that evaluate regulatory requirements, hiring needs and future growth plans from the outset are better positioned to scale efficiently while maintaining compliance.

Frequently asked questions

Can a foreign company own 100% of a business in Thailand?

Yes, in some cases. Businesses that qualify for BOI promotion may be eligible for 100% foreign ownership. Other activities may be restricted under the FBA or require an FBL.

What’s the difference between a Thai limited company and a branch office?

A Thai limited company is a separate legal entity incorporated in Thailand. A branch office is an extension of the foreign parent company, which remains legally responsible for the branch’s operations.

Can a representative office generate revenue?

No. Representative offices are limited to non-commercial activities such as market research, supplier coordination and liaison services. They cannot sell products or services or issue invoices.

Can a representative office hire employees?

Yes, but strictly for non-commercial roles.

A representative office can directly hire local Thai personnel and sponsor work permits for foreign expat staff. However, they are legally restricted to tasks that support the foreign parent company (such as market research or quality control) and cannot hire staff to conduct sales or revenue-generating activities.

Can I hire employees before establishing a Thailand entity?

Yes. An EOR allows businesses to legally employ workers in Thailand before establishing a local entity, making it easier to begin operations while preparing for long-term expansion.

Choosing the right entity is only the beginning

Choosing between a Thai limited company, branch office and representative office is only one part of a successful market entry strategy. The right structure should align with your commercial objectives, workforce plans and long-term growth.

Companies that evaluate entity options alongside ownership requirements, hiring needs and future growth are better positioned to enter the market efficiently and scale with confidence.
