Regional Head Office in Thailand 

Thailand has emerged as a key destination for multinational corporations seeking to establish a centralized base for managing operations across Southeast Asia and beyond. With its strategic location, competitive operating costs, and attractive tax incentives, Thailand offers a compelling environment for establishing a Regional Head Office (RHO), particularly under modern frameworks, such as the International Business Center (IBC) regime. 

However, while the opportunities are significant, establishing a Regional Head Office in Thailand requires careful legal, regulatory, and tax planning

What is a Regional Head Office in Thailand?

A Regional Head Office (RHO) is a business entity established in Thailand to provide centralized management and support services to affiliated companies, branches, or subsidiaries located in Thailand and abroad.

Typically, a RHO carries out functions such as:

• Strategic planning and business coordination
• Financial and treasury management
• Human resource management and training
• Marketing and regional sales support
• Research and development (R&D)
• Technical and advisory services

While the term “RHO” is widely used in practice, Thailand’s current legal and tax framework primarily supports such activities through the International Business Center (IBC) regime, which replaced earlier schemes, such as the ROH and International Headquarters (IHQ).

Legal Framework Governing Regional Head Offices

Establishing a Regional Head Office in Thailand involves compliance with several key laws:

1. Immigration Act B.E. 2522 (1979)

Governs the entry, stay, and work authorization of foreign personnel employed by the RHO.

2. Foreign Business Act B.E. 2542 (1999)

Regulates foreign ownership and business activities in Thailand. Certain service activities performed by RHOs may fall within restricted categories, requiring a Foreign Business License (FBL), or a Foreign Business Certificate (FBC). 

3. Civil and Commercial Code

Provides the legal basis for company incorporation, governance, and shareholder rights.

4. Revenue Code of Thailand

Governs corporate income tax, withholding tax, and eligibility for tax incentives under the IBC regime.

5. Investment Promotion Act B.E. 2520 (1977)

Provides additional incentives and privileges for companies approved by the Board of Investment.
