When a foreign company decides to establish a presence in Thailand, one of the first and most important decisions it must make is choosing the right legal structure. While most people are familiar with company registration in Thailand in the form of a Thai limited company, there are two other entry vehicles worth understanding: the branch office and the representative office.
Each structure carries a distinct set of rights, restrictions, tax implications, and compliance obligations. Choosing the wrong one at the outset can result in costly restructuring down the line. This guide explains all three options clearly so you can make an informed decision from the start.
Option 1: The Thai Limited Company
A Thai private limited company (บริษัทจำกัด) is the most commonly used structure for foreign investors wishing to operate a business in Thailand. It is a separate legal entity, meaning the company can own assets, enter into contracts, employ staff, and conduct business entirely in its own name.
Key characteristics
- Separate legal entity from the foreign parent (if any)
- Can conduct any type of business, subject to the Foreign Business Act
- Shareholders' liability is limited to their invested capital
- Requires a minimum of two shareholders
- Subject to Thai corporate income tax at 20%
- Can open a Thai bank account, hold property, and obtain business licences
Who it suits: Foreign investors who want to actively conduct business in Thailand, either independently or in partnership with Thai shareholders. It is the most flexible and commercially powerful structure.
Key consideration: Under the Foreign Business Act (FBA), foreign nationals cannot hold majority shares in most categories of business without additional approvals — such as a Foreign Business Licence, BOI promotion, or the US-Thailand Treaty of Amity for American investors.
Option 2: The Branch Office
A branch office is an extension of a foreign parent company operating within Thailand. Unlike a limited company, the branch is not a separate legal entity — it is legally part of the foreign parent, which means the parent company bears full liability for the branch's activities and obligations in Thailand.
Key characteristics
- Not a separate legal entity — the parent company is fully liable
- Can generate revenue and conduct business in Thailand
- Subject to Thai corporate income tax on income derived from Thailand
- Must obtain a Foreign Business Licence (FBL) before commencing operations
- Requires registration with the Department of Business Development (DBD)
- Cannot own land in Thailand
Who it suits: Established foreign companies that want to conduct revenue-generating activities in Thailand while maintaining a direct link to the parent entity — for example, in construction, consulting, or services.
Key consideration: Because the branch is not a separate legal entity, the full financial exposure of the Thai operations rests with the foreign parent. This unlimited liability is a significant disadvantage compared to the limited liability protection of a Thai limited company.
Option 3: The Representative Office
A representative office is the most restricted of the three structures. It allows a foreign company to have a physical presence in Thailand but cannot generate income or conduct commercial transactions. Its purpose is limited to non-revenue activities on behalf of the foreign parent.
Permitted activities include
- Sourcing goods or services for the parent company
- Checking and controlling the quality of goods purchased in Thailand
- Providing advice and assistance to customers purchasing goods from the parent
- Reporting on business developments in Thailand to the parent company
- Marketing and promotional activities (but not direct sales)
Who it suits: Foreign companies that want a market presence in Thailand for sourcing, research, or liaison purposes — but are not ready or do not need to conduct direct business operations here.
Key consideration: The strict limitation on revenue-generating activity means a representative office is unsuitable for any company that intends to sell goods or services within Thailand.

How to Decide: Key Questions to Ask
Are you planning to generate revenue in Thailand?
If yes, eliminate the representative office. Your choice is between a limited company and a branch office.
Do you want liability protection from Thai operations?
If yes, a limited company is preferable. The branch office exposes the entire foreign parent to Thai liabilities.
Does your parent company want to operate under its own name and brand in Thailand directly?
If yes, a branch office may be appropriate — it operates as a direct extension of the parent rather than as a new, separately incorporated entity.
Are you only looking to source, research, or maintain a liaison presence?
If yes, a representative office offers the lowest cost and simplest compliance structure — provided you genuinely do not intend to generate income.
Are you a foreign national seeking majority or 100% ownership?
If yes, you need to plan carefully around the Foreign Business Act — regardless of whether you choose a limited company or a branch office.
Company Registration in Thailand: The Process Differs by Structure
The registration process for each structure is handled through the Department of Business Development (DBD) but differs in its requirements.
A limited company follows the standard multi-step process: name reservation, Memorandum of Association, statutory meeting, and registration with the DBD. A Foreign Business Licence may be required depending on ownership and business type.
A branch office requires the submission of the parent company's documents (including its own certificate of incorporation and Articles of Association), plus a Foreign Business Licence application. The process is generally more document-heavy and takes longer to complete.
A representative office also requires DBD registration and a Foreign Business Licence, but the application emphasises the non-commercial nature of the office's activities.
In all three cases, working with a specialist legal adviser in Thailand will significantly streamline the registration process and reduce the risk of delays or rejected applications.
