Sole proprietorship:

         In general foreigners are prohibited by Thai law to conduct business as a sole proprietor. One exception is for citizens of the United States of America who register with the countries Department of Business Development under the U.S. – Thailand Amity Treaty. By doing this the law allows them to run sole proprietorships in most industries.


         Two types of business partnerships are recognized and can be legally registered with the Commercial Registration Office. The registration fee will be assessed as 1 pct. of the registered capital and will cost between 1,000 and 5,000 Thai Baht.

Ordinary Partnerships:

          These can be established by law with a minimum of 2 owners. Ordinary partnerships have no requirement to register with the Commercial Registration Office, however, many individuals involved in such a partnership do so because they wish to be taxed as juristic individuals.

          These partnerships are required to issue annual financial statements and to pay corporate income taxes. If not, income has to be stated on each partner’s individual tax return.

Thai Limited Liability Partnership:

         This is known as a Thai LLP and allows for 2 types of partners.

  • General Partners: These individuals are permitted to manage the business. They are fully liable for the said partnerships financial obligations.
  • Limited Partners: These individuals are NOT permitted to manage the business. Their financial liability is limited to the sum of capital contributed to the LLP.

These partnerships must register with the Commercial Registration Office and tax wise are classed as corporate entities. Thai LLP’s are required to make an annual financial statement.

Thai Limited Companies:

        Limited companies are governed by Thailand’s Civil and Commercial Code. It is a requirement for every Private Limited company to register their Memorandum of Association and their Articles of Association.

        To establish a company, 3 promoters are required before registration can be accepted. Each of these promoters must be at least 20 years old and must hold at least one share in the company. Shareholders do not have to be Thai citizens. but foreign shareholders can only hold a maximum of 49% shares in a company.

       A Limited Company must have at least 3 shareholders at all times. This is a Thai law which should be adhered to.

        While all shares must be subscribed to upon incorporation, only 25 pct. of these have to be paid up. There is a minimum share price of 5 Thai Baht. It is possible for some shares to have preferential voting power attached, but every share must be given at least one vote.


Business Registration: 

All businesses operating in Thailand must be registered with the Department of Business Development (DBD) under the Ministry of Commerce. The registration process involves submitting the necessary documents, including the Memorandum of Association, Articles of Association, and details of shareholders and directors.

Some business activities are restricted for foreigners in Thailand, particularly under the Foreign Business Act. Certain sectors may require obtaining specific licenses or meeting ownership criteria to operate as a foreigner.

Businesses in Thailand are subject to various taxes, including corporate income tax, value-added tax (VAT), and specific business taxes. Understanding and complying with the tax laws, including filing tax returns and paying taxes on time, is crucial for businesses operating in Thailand.

Labour Laws:
