Expanding your business internationally is becoming common in today’s globalized business industry. Thailand is one of the countries that many entrepreneurs consider a prime location to grow their business. However, before starting a business in Thailand, it is crucial to understand the critical requirements for company registration in Thailand to ensure a smooth and successful process.

Business Structures in Thailand

In Thailand, there are several types of business structures, including sole proprietorships, partnerships, limited partnerships, private limited companies, public limited companies, and branches of foreign companies. The most common type of business structure for foreigners in Thailand is a private limited company.

Key Requirements for Company Registration (Thai company register)

To register a private limited company in Thailand, the following requirements must be met:

  • Business Name Reservation: The company’s name must be unique and not similar to any other registered companies in Thailand. It is advisable to reserve several names to increase the chances of approval.
  • Shareholder and Director Requirements: A minimum of three shareholders and one director is required for a private limited company. At least one shareholder and director must be a Thai citizen.
  • Registered Office Address: The company must have a registered office address in Thailand, where the company’s legal documents can be delivered.
  • Memorandum and Articles of Association: These are the company’s founding documents that outline the company’s objectives, shareholders’ rights and responsibilities, the board of directors’ duties, and other necessary information.
  • Paid-up Capital Requirements: A private limited company’s minimum registered capital requirement is THB 1 million, of which at least 25% must be paid within three months of the company’s registration.
  • Tax ID Registration: After registering the company, a Tax ID card must be obtained for the company to conduct business in Thailand legally.

Additional Requirements for Certain Business Types

Foreign-owned companies and companies in certain industries may require additional requirements. For example, if the company is wholly foreign-owned, it must obtain permission from the Foreign Business Act to operate in Thailand legally. Some industries, such as banking and finance, require additional licenses and permits from the relevant authorities.

When the company’s name is changed to another name, the company’s registration will automatically be cancelled, and a new letter of approval must be obtained.

The need to register a business in Thailand varies depending on the type of business. When starting a manufacturing or trading enterprise, it is advisable to register the business under a name that is not similar to other existing companies in Thailand or registered as a trademark to guarantee protection from any competitors’ infringement of trademarks and business names. 


In conclusion, understanding the critical requirements for company registration in Thailand is essential for any entrepreneur looking to expand their business in Thailand. These requirements include business name reservation, shareholder and director requirements, registered office address, memorandum and articles of association, paid-up capital requirements, and tax ID registration. Additional conditions may apply to specific business types, such as foreign-owned companies or companies in specific industries. Complying with these requirements will ensure a smooth and successful registration process in Thailand.
