In Thailand, it is generally necessary for a foreign investor to have Thai participation in its venture, although 100 percent foreign investment is possible, but only in certain key industries. A person, Thai or alien, may engage in business in the form of a single proprietorship, limited company, partnership, a joint venture, a branch of a foreign corporation, or a representative/regional office.


Three types of partnerships in Thailand differ principally in the liability attached to each. An unregistered ordinary partnership has partners who are all jointly liable, without any limitation on the partnership’s total obligations. This type of partnership is not a legal entity, and is subject to taxation as if it were an individual. A registered ordinary partnership is a juridical entity having a separate and distinct personality from each of the partners by virtue of its registration with the Commercial Registrar. A registered ordinary partnership is treated as a corporate entity for income tax purposes. A limited partnership is one in which there are one or more partners whose individual liabilities are limited to their respective contributions, and one or more partners jointly liable without any limitation on all the obligations of the partnership. A limited partnership is taxed as a corporate entity.

Private Limited Company

A Thai private limited company is similar to what is commonly referred to as a corporation. The company may be wholly owned by aliens. However, in those business activities reserved for Thai nationals, aliens’ participation is generally allowed up to 49 percent. The liability of the shareholders is limited to the par value of the authorized capital. The liability of the directors, however, may be unlimited if so provided in the company’s memorandum of association or the articles of incorporation. The limited company is managed by a board of directors according to the company’s charter and by-laws. Although there is no established minimum level of capitalization, the private limited company’s capital must be sufficient to accomplish its objectives. All of the shares must be subscribed to, and at least 25 percent of the subscribed shares must be paid up. Both common and preferred shares of stock may be issued, but all shares must have voting rights. Thai law prohibits the issuance of shares with no par value; it also stipulates that only shares with par value of THB
5 or above may be issued. Thai corporate law has some features, which may be unfamiliar to foreign business people. Among these is the prohibition on treasury shares, and a rule that a private limited company’s shareholders must never be fewer than three at all times. In addition, nonvoting stock, whether common or preferred, is not permitted; and the original authorized capital stock must be subscribed in full.

Joint Venture

A joint venture may be described in accordance with general practice as a group of persons (natural and/or juristic) entering into an agreement in order to carry on a business together. It has not yet been recognized as a legal entity under the Civil and Commercial Code. However, income from a joint venture is subject to corporate taxation under the Revenue Code, which classifies it as a single entity.

Branch of a Foreign Corporation

A company incorporated under foreign laws may establish a branch office to do business in Thailand. Branch offices are required to maintain only those accounts relating to the activities of the branch in Thailand. It is important, however, to clarify beforehand what constitutes income subject to Thai tax because the Revenue Department may consider revenues directly earned by the foreign head office from sources within Thailand as subject to Thai tax. As a condition for approval of an Alien Business License for a branch of a foreign corporation, minimum capital amounting to THB3 million must be brought into Thailand. This amount may be changed by subsequent ministerial regulations. A branch office may exist for an indefinite period up to its date of dissolution.

Representative Office of a Foreign Corporation

A foreign entity may establish a representative office in Thailand to engage in limited non-revenue earning activities. These activities are restricted to:

  • Searching for local sources of goods or services for its head office, inspecting and controlling the quality and quantity of goods procured by its head office.

  • Providing advice in various fields relating to products directly sold by its head office to local distributors or consumers.

  • Disseminating information about new products and services of its head office.

  • Reporting to its head office on local business developments and activities.

The minimum capital contributions with respect to branches are also applicable to representative offices.

Regional Office of a Multinational Corporation

A multinational corporation may establish a regional office in Thailand to engage in limited non-revenue earning activities. These activities are restricted to:

  • Contacting, coordinating, and supervising the activities of affiliated businesses in the region.

  • Providing services to affiliated branches or subsidiaries such as: advisory and management services; training and personnel development; financial management; marketing control and sales promotion; and product research and development.

All expenditures incurred by the regional office must be borne by the head office of the multinational corporation. The minimum capital requirements in respect to branches are also applicable to regional offices.
