For foreign companies seeking to establish a foothold in Southeast Asia without committing to full-scale commercial operations, the representative office offers a strategic and legally recognized entry point. Thailand's stable infrastructure, central location, and pro-business environment make it an attractive destination for multinational corporations looking to explore market opportunities, conduct research, or coordinate regional activities . However, the representative office structure operates under strict legal limitations that foreign investors must understand before proceeding. This comprehensive guide provides an in-depth examination of representative offices in Thailand, covering the legal framework, permitted activities, requirements, establishment process, tax implications, and strategic considerations for 2026.

What Is a Representative Office?

A representative office is a form of business presence established by a foreign company to carry out specific non-commercial activities in Thailand on behalf of its head office abroad . It is not a separate legal entity but rather an extension of the foreign parent company . Unlike a branch office or Thai limited company, a representative office is prohibited from generating income, issuing invoices, or entering into contracts with customers in Thailand . All operating expenses must be funded exclusively by the head office through inward remittances .

This structure serves as a liaison or support arm, helping foreign companies understand the Thai market, build relationships with local partners, and prepare for potential future expansion without the complexity and regulatory burden of a full commercial entity .

The Legal Framework: Foreign Business Act Exemption

Representative offices in Thailand are governed primarily by the Foreign Business Act B.E. 2542 (1999) (FBA) , which generally restricts foreign entities from engaging in business activities in Thailand without a license . However, pursuant to the Ministerial Regulation Prescribing Businesses Which Do Not Require a Foreign Business Licence (No. 3) B.E. 2560 (2017), representative offices are exempt from the requirement to obtain a Foreign Business License (FBL) , provided they strictly adhere to permitted non-revenue activities .

This exemption makes the representative office an attractive alternative to the more burdensome FBL application process, which can be lengthy, costly, and uncertain . However, the exemption is conditional: any activity beyond the permitted scope may trigger FBA compliance requirements and subject the office to penalties or forced closure .

Permitted Activities of a Representative Office

Strictly prohibited activities include: accepting purchase orders, making sales offers, negotiating contracts with individuals or legal entities, providing services for compensation, issuing invoices, or receiving payments from customers . Any violation of these restrictions constitutes doing business in Thailand without authorization and may result in penalties under the FBA .

Requirements for Establishing a Representative Office

Parent Company Qualifications

The foreign parent company must be a legally registered entity in its home country and must have been operating for a reasonable period—typically at least one to three years . Authorities may request audited financial statements, certificates of incorporation, and corporate records to verify the parent company's legitimacy and financial capacity .

Capital Requirements

The Thai government requires a minimum capital investment of 2 million baht for a representative office . This amount must be remitted from the parent company to support operational expenses and must be maintained throughout the office's operations . While some sources suggest a higher operating budget may be required depending on staffing and business scope, the statutory minimum remains THB 2 million .

Office Address and Facilities

A representative office must maintain a physical office address in Thailand . Virtual offices are generally not accepted for registration, and the office must have appropriate facilities commensurate with its intended activities.

Staffing and Employment

Representative offices may employ both Thai and foreign staff. Foreign employees must obtain Non-Immigrant B visas and work permits from the Ministry of Labour . The number of foreign staff permitted depends on the nature and size of the office's operations, as well as the capital remitted . While there is no statutory ratio of Thai to foreign employees for representative offices, maintaining a reasonable balance supports the application's credibility.

Appointment of a Manager

The representative office must appoint a manager who resides in Thailand . This individual is responsible for overseeing operations, ensuring compliance with Thai regulations, and serving as the primary point of contact for regulatory authorities.

Registration Process: Step by Step

The establishment of a representative office is generally straightforward and takes approximately seven working days from the submission of a complete application . The process involves several key steps:

Step 1: Document Preparation

The parent company must prepare the following documents, all of which must be notarized and, in most cases, legalized by the Royal Thai Embassy or Consulate in the parent company's home country :

Certificate of incorporation

Memorandum and articles of association

Audited financial statements (typically for the last three years)

Board resolution approving the establishment of the representative office

Power of attorney appointing the Thai representative or manager

Description of intended activities in Thailand

Parent company's business profile and registration documents

Step 2: Application Submission

The application is submitted to the Department of Business Development (DBD) under the Ministry of Commerce . The DBD reviews the business objectives, activities, and financial capacity of the parent company to ensure compliance with the FBA and ministerial regulations.

Step 3: Approval and Registration

Upon approval, the representative office receives a registration certificate and may begin operations within the approved scope .

Step 4: Tax Registration

Although the representative office does not generate income, it must register for a Tax Identification Number with the Revenue Department . This is necessary for fulfilling withholding tax obligations and filing annual returns .

Step 5: Visa and Work Permit Applications

Foreign staff must apply for Non-Immigrant B visas at a Thai embassy or consulate abroad, followed by work permits from the Ministry of Labour in Thailand .

Taxation and Compliance

Corporate Income Tax Exemption

Because representative offices do not earn profits in Thailand, they are generally exempt from corporate income tax . However, there is a limited exception: interest earned from leftover funds provided by the head office must be included in the calculation for corporate income tax .

Withholding Tax and Other Obligations

Despite the CIT exemption, representative offices must comply with several tax and reporting obligations:ObligationDescriptionWithholding TaxTax must be withheld on employee salaries, rent, and certain service payments Social Security ContributionsEmployers must contribute to the Social Security Fund for Thai employeesPersonal Income TaxEmployees' salaries are subject to PIT, which must be filed and remitted by the employer Annual Financial StatementsAudited financial statements must be submitted to the DBD annually Tax ReturnsCorporate income tax returns must still be filed to confirm non-income status 

Failure to comply with these obligations can result in fines, penalties, or legal action .

Benefits of Establishing a Representative Office

1. Market Entry Without Full Commitment

A representative office allows foreign companies to test the Thai market with minimal financial and regulatory risk before committing to a full-scale subsidiary or branch .

2. Cost-Effective Expansion

Compared to establishing a Thai limited company or branch office, a representative office requires lower capital investment and simpler operational costs .

3. Enhanced Business Credibility

Having a physical presence in Thailand demonstrates commitment to the market and strengthens credibility with local partners, distributors, and customers .

4. Strategic Regional Hub

Thailand's central location in Southeast Asia makes it an ideal base for coordinating regional activities in neighboring countries such as Vietnam, Malaysia, and Cambodia .

5. Exemption from Foreign Business License

Representative offices benefit from the ministerial exemption to the FBA, avoiding the lengthy and uncertain FBL application process .

Transitioning to Full Business Operations

Many foreign companies use a representative office as a stepping stone toward more substantial business structures. Once market potential is confirmed and the company is ready to engage in commercial activities, the representative office can be transitioned to:

Thai Limited Company: The most common structure for ongoing commercial operations, offering limited liability and full revenue-generating capacity 

Branch Office: Allows the foreign parent company to conduct business directly in Thailand while retaining a single legal identity 

BOI-Promoted Company: For qualifying activities, Board of Investment promotion can provide tax incentives and foreign ownership privileges 

The transition requires careful planning to ensure continuity of operations and compliance with Thai law. Companies should consult legal professionals to structure the transition properly and avoid regulatory gaps .

Conclusion

Establishing a representative office in Thailand is an effective, low-risk strategy for foreign companies seeking to explore the Thai market, conduct research, and build relationships before committing to full-scale commercial operations. The structure offers a compliant pathway under the Foreign Business Act, requiring THB 2 million in capital and strict adherence to five permitted non-revenue activities.

However, the representative office is not a permanent solution for businesses intending to generate revenue in Thailand. Its strict limitations and dependence on head office funding make it suitable primarily for preliminary exploration and support functions. Companies with long-term commercial ambitions should view the representative office as a preparatory step toward a Thai limited company, branch, or BOI-promoted entity.

Given the complexity of Thai regulations and the consequences of non-compliance, engaging qualified legal professionals is essential to ensure proper registration, ongoing compliance, and a seamless transition to full operations when the time comes .
