Foreign Business Act in 2019

Businesses involving foreign investors in Thailand are typically registered as a Limited Company and must have the status of a Thai legal entity. This means that more than 50% of the company’s shares must be held by Thai citizens or Thai companies.

Legal Framework

This requirement is based on the Foreign Business Act.
If 50% or more of the shares are owned by foreign shareholders, the company is classified as a foreign legal entity.

The law includes a list of business activities restricted to Thai entities, divided into three categories:

Restricted Business Categories

Category 1 — Completely Prohibited for Foreign Companies

  • media (press, radio)
  • agriculture
  • land trading

Category 2 — Related to National Security, Culture, or Natural Resources

  • weapons industry
  • antiques
  • mining and natural resource extraction

Foreign companies may engage in these activities only with special permission.

Category 3 — Businesses Where Thais Are Not Ready to Compete

  • accounting services
  • legal services
  • architecture
  • advertising

Foreign companies may operate in these sectors only after obtaining a Foreign Business License.

Practical Reality

These lists cover almost all types of business activities:

  • Category 1 → completely closed to foreign businesses
  • Categories 2 & 3 → require a Foreign Business License, which is difficult to obtain

For example:

  • companies promoted by the Thailand Board of Investment (BOI) may obtain such a license
  • but only after receiving a BOI certificate

However, many common businesses do not qualify, including:

  • real estate sales
  • restaurants
  • consulting services
  • agency services
  • guesthouses

New Regulation (June 25, 2019)

The Ministry of Commerce issued a regulation exempting certain activities from the Foreign Business Act. These relate to intra-group (operational) services, including:

  • lending funds to affiliated or subsidiary companies
  • leasing office space to branches or subsidiaries (including utilities)
  • providing consulting services in:
    • management
    • marketing
    • human resources
    • information technology

to affiliated or subsidiary companies

Definition of Affiliated and Subsidiary Companies

The regulation defines such companies as those where:

  • a company holds 25% or more of shares in another company

In such cases:

  • a company may be 100% foreign-owned
  • if its activities are limited to the exempted services listed above
