Representative Offices and Branch Offices in Thailand | What They Can and Cannot Do, and How to Set Them Up [Series Part 2]

A detailed look at Thailand's representative office and branch office structures — their legal status, permitted activities, setup procedures, and costs. Part 2 of a 5-part series on Thailand market entry for Japanese companies.

Key Takeaways

  • A representative office is an extension of the Japanese parent — revenue-generating activities are not permitted
  • A branch office may conduct certain revenue-generating activities, but FBA-regulated business categories require a Foreign Business License (FBL)
  • In both structures, the Japanese parent company bears direct legal liability — the key difference from a Thai subsidiary

Introduction

Part 1 of this series provided an overview of Thailand’s five main entry structures. In Part 2, we take a closer look at the two structures with relatively straightforward setup procedures: the representative office and the branch office — examining their legal status, permitted activities, and setup process.


Representative Office

A representative office is a Thai presence established by the Japanese parent company. It does not have independent legal personality in Thailand — legally, it is treated as part of the Japanese entity.

Permitted Activities

Under rules established by Thailand’s Revenue Department and the Department of Business Development (DBD), a representative office is limited to the following types of activities:

Permitted ActivityExamples
Market research and intelligenceStudying market trends, gathering competitive information
Liaison with the parentCoordinating communications between parent and Thai parties
Quality control supportInspecting products or materials on behalf of the parent
Technical servicesExplaining or demonstrating parent company products
Sourcing/procurement supportIntroducing Thai suppliers to the parent (contracts remain with parent)

Not permitted: Accepting orders, entering into contracts, receiving payment, or any activity through which the representative office itself earns revenue.

Tax Treatment

Where a representative office operates strictly within its permitted scope, it generally does not generate taxable income in Thailand. However, if Thai tax authorities determine that the office is in fact conducting revenue-generating activities, it may be classified as a permanent establishment (PE) and subject to Thai corporate income tax.

Setup Procedure

Establishing a representative office primarily involves an application to Thailand’s Department of Business Development (DBD).

  1. Document preparation

    • Application form (as prescribed under the Foreign Business Act)
    • Japanese parent company certificate of incorporation (with Apostille, Thai translation)
    • Board resolution authorizing establishment of the Thailand office
    • Office lease agreement
    • Passport copies of the representative
  2. Application and review

    • Submit application and supporting documents to the DBD
    • Review typically takes approximately 2–3 months
  3. Certificate and registration

    • Obtain the Foreign Business Certificate
    • Arrange work permits and non-immigrant B visas for each working employee

Cost Indicators

ItemApproximate Range
Government feesSeveral thousand to tens of thousands of baht
Legal/accounting feesVaries by firm and scope
Registered capital requirementMinimum THB 3 million (remittance from parent required)

When a Representative Office May Be Appropriate

  • When the primary purpose is market research or partner identification before committing to a full market entry
  • When establishing a physical presence is the priority, with substantive operations planned for the future
  • When activities are primarily limited to parent company management or quality oversight

Branch Office

Like a representative office, a branch office is legally part of the Japanese parent — it has no independent legal personality in Thailand. However, unlike a representative office, a branch office may engage in certain revenue-generating activities. The activities permitted depend on whether the business falls within regulated categories under the Foreign Business Act (FBA).

FBA Implications for Branch Offices

If the branch’s business activities fall within the FBA’s restricted categories (Annexes 2 or 3), a Foreign Business License (FBL) is required.

  • Operating without an FBL in a regulated category can expose both the branch and parent to criminal liability
  • BOI promotion can in some cases exempt operations from FBA restrictions (though BOI promotion for branch offices is limited to certain activity types)
  • Categories listed in Annex 1 (absolute prohibitions) cannot be entered by any foreign entity, including branch offices

Parent Company Liability

All contractual obligations and damages arising from branch activities are the direct liability of the Japanese parent company. This is the most significant risk consideration for the branch structure.

Setup Procedure

  1. FBL application (if required)

    • Apply to the DBD or the Foreign Business Committee for a Foreign Business License
    • Review timelines vary and can extend over several months
  2. Branch registration

    • File branch registration with the DBD
    • Required documents include the parent’s incorporation certificate, board resolution, and power of attorney
  3. Registered capital remittance

    • Minimum THB 3 million in capital must be remitted (installment payments are permitted)
  4. Tax registration and work permits

    • Register for corporate income tax with the Revenue Department
    • Obtain work permits for foreign employees

When a Branch Office May Be Appropriate

  • When executing a specific project contract (e.g., construction or engineering) as a one-off engagement
  • When the Japanese parent is required to be the direct contracting party
  • When the company wishes to begin operations through a branch while planning to transition to a subsidiary later

Key Risks Common to Both Structures

Conducting Activities Beyond the Permitted Scope

If either a representative office or branch office conducts activities outside its permitted scope, legal and tax exposure can arise. A particularly common risk pattern is a nominally representative office that is in practice accepting orders or entering contracts with Thai customers — which may lead to PE recognition by Thai tax authorities.

Transitioning to a Subsidiary

As business activities expand, many companies reach a point where they wish to transition to a Thai limited company (subsidiary). This requires a separate incorporation process — meaning the total cost of a representative office followed by a transition may exceed the cost of incorporating a subsidiary from the outset.


Summary

A representative office is designed for market research and liaison functions. A branch office can conduct limited revenue-generating activities but carries the risk of direct parent liability. Neither structure has independent legal personality — the key distinction from a Thai subsidiary.
