  4. The basic accounting principles practiced in the United States are accepted in Thailand, as are accounting methods and conventions as sanctioned by law. The Institute of Certified Accountants and Auditors of Thailand is the authoritative group promoting the application of generally accepted accounting principles.
Audited financial statements of juristic entities (that is, a limited company, a registered partnership, a branch, or representative office, or a regional office of a foreign corporation, or a joint venture) must be certified by an authorized auditor and submitted to the Revenue Department and (except for joint ventures) to the Commercial Registrar for each accounting year.
Auditing standards conforming to international auditing standards are, to the greater extent, recognized and practiced by authorized auditors in Thailand.
Public Limited Companies registered in Thailand may, subject to compliance with the prospectus, approval, and other requirements, offer shares, debentures and warrants to the public and may apply to have their securities listed on the Stock Exchange of Thailand (SET).
The simplest form for establishing and operating a business is the sole proprietorship. Sole proprietorships are unincorporated businesses established by one person, the owner, doing business on his own account. The owner is personally entitled to all profits and responsible for all losses arising from the business.
Thai and Western concepts of partnership are broadly similar. Thailand provides for three general types of partnerships:
  1. Unregistered ordinary partnerships, in which all partners are jointly and wholly liable for all obligations of the partnership
  2. Registered ordinary partnerships. If registered, the partnership becomes a legal entity, separate and distinct from the individual partners
  3. Limited partnerships. Individual partner liability is restricted to the amount of capital contributed to the partnership. Limited partnerships must be registered.
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 the joint venture is subject to corporate taxation under the Revenue Code, which classifies it as a single entity.
There is no special requirement for foreign companies to register their branches in order to do business in Thailand. However, those business activities fall within the scope of one or more laws or regulations which require special registration, either before or after the commencement of activities. Foreign business establishments must, therefore, follow generally accepted procedures..
As a condition for approval of an Alien Business License to a branch of a foreign corporation, working capital amounting to a total of five million baht in foreign exchange must be brought into Thailand within certain intervals over a four-year period.
The branch may be allowed to operate for a period of five years, unless a shorter period is indicated in the application as a result of a contract to be performed in Thailand. Extension of the original duration of the license to operate may be granted, provided the working capital required to be brought into Thailand is met.
A representative office of foreign corporations may also be established to engage in limited "non-trading" activities, such as sourcing of goods or services in Thailand for its head office or inspecting and controlling quality of goods which its head office purchases in Thailand. Other activities can cover disseminating information about new products and services of its head office, and reporting to its head office on local business development and activities.
The Alien Business Act describes an alien as a natural person or juristic entity without Thai nationality, including a company with half or more than half if its shares held by aliens, or company with half or more than half of its shareholders being aliens.
The Act classifies businesses into 3 categories, details of which may be summarized as follows:
  1. Category A
