Why Register a Company in Thailand?

Registering a company in Thailand offers several strategic advantages. Thailand is known for its open market policies, skilled workforce, and robust infrastructure. With free trade agreements, government incentives, and access to major ASEAN markets, it has become a preferred destination for foreign investment and business expansion.

Whether you plan to start a trading company, manufacturing operation, tech firm, or service-based enterprise, registering a company in Thailand provides the legal foundation for sustainable growth and local presence.

Common Types of Companies in Thailand

Understanding the types of legal entities available is crucial for choosing the right business structure. The most commonly registered company types in Thailand include:

1. Thai Limited Company (Private Limited Company)

This is the most popular business entity for both Thai nationals and foreign investors. A Thai Limited Company offers limited liability to its shareholders and requires a minimum of three shareholders and one director. It is ideal for most small and medium-sized enterprises.

2. Representative Office

A representative office can be set up by a foreign company to conduct non-revenue-generating activities such as market research, product sourcing, or quality control. It cannot earn income in Thailand and is suitable for companies exploring the market.

3. Branch Office

A branch office allows a foreign company to operate a revenue-generating business in Thailand under the parent company’s name. It must be registered and comply with Thai business regulations.

4. BOI-Promoted Company

Companies that qualify under the Board of Investment (BOI) are eligible for incentives such as tax exemptions and foreign ownership benefits. This is suitable for businesses in promoted sectors like tech, manufacturing, or clean energy.

Company Registration Requirements in Thailand

To register a company in Thailand, the following general requirements must be fulfilled:

  • Company Name Reservation
    Choose and reserve a unique company name that complies with the Department of Business Development (DBD) guidelines.

  • Shareholders and Directors
    A minimum of three shareholders (can be individuals or juristic persons) is required. At least one director must be appointed.

  • Registered Office Address
    A valid physical address in Thailand must be provided as the registered office of the company.

  • Memorandum of Association (MOA)
    The MOA must be filed with the DBD and include information such as the company name, registered capital, objectives, and shareholder details.

  • Articles of Association (Bylaws)
    These define the company’s internal management and rules.

  • Minimum Registered Capital
    The capital requirement depends on whether the business will employ foreign staff or apply for foreign business licenses. Typically, a minimum of 2 million THB is required for a 100% foreign-owned company, or 1 million THB per foreign work permit.

  • Corporate Income Tax Registration
    Once registered, the company must obtain a Tax Identification Number and, if applicable, register for VAT.

  • Social Security Registration
    Companies with employees must register for Social Security contributions.

Step-by-Step Company Registration Process in Thailand

Step 1: Name Reservation

Submit a name reservation application through the DBD’s online system. The name must not be identical or similar to existing registered companies.

Step 2: File the Memorandum of Association

File the MOA with the DBD, including the approved company name, business objectives, registered capital, and shareholder information.

Step 3: Convene the Statutory Meeting

During this meeting, the company adopts its Articles of Association, appoints the board of directors, and finalizes the share subscription.

Step 4: Company Registration

Submit the company registration application to the DBD within three months of the statutory meeting. The company is officially formed upon registration.

Step 5: Tax and VAT Registration

After incorporation, apply for a company tax ID. If your business exceeds the annual threshold for VAT registration (1.8 million THB), register for VAT with the Revenue Department.

Step 6: Open a Corporate Bank Account

Once the company is registered, you can open a business bank account in Thailand using the company documents and authorized signatory’s ID.

Step 7: Work Permit and Visa Applications (if applicable)

For foreign directors or employees, apply for a business visa (Non-B) and obtain a work permit from the Ministry of Labour.

Foreign Ownership Considerations

In general, foreigners can own up to 49% of a Thai limited company unless the company is BOI-promoted or obtains a Foreign Business License (FBL). Some business sectors are restricted under the Foreign Business Act, requiring legal structuring or special permissions.

To facilitate full foreign ownership, businesses may:

  • Apply for BOI promotion

  • Establish a US-Thai Treaty of Amity company (for US citizens only)

  • Use a nominee shareholder structure (subject to legal scrutiny and restrictions)

Our legal team ensures all ownership structures comply with current Thai regulations, avoiding risks of non-compliance.

Compliance and Ongoing Obligations

After registration, companies in Thailand must comply with local laws and fulfill annual requirements:

  • Accounting and Tax Filing
    Maintain monthly accounting records and submit annual financial statements and tax returns.

  • Annual Shareholders’ Meeting
    Hold a meeting annually to review the company’s performance and approve financial reports.

  • Work Permit Renewals
    Ensure work permits and business visas are renewed before expiry to maintain legal employment of foreign staff.

  • Company Updates
    Any changes to shareholders, directors, address, or capital must be registered with the DBD.
