  • The company must have a company name approved by the Department of Business Development (DBD). For more information, please see our blog post here

What documents are required to register a Thai Limited Company?

Power of attorney empowering the authorized director(s): A power of attorney is required to empower the branch office’s authorized director(s) to act on behalf of the parent company.

What documents are required to register a Representative Office?

The registration process for a Representative Office in Thailand involves submitting specific documents to the Department of Business Development (DBD) in Bangkok or the Provincial Office of Business Development in other provinces. The following documents need to be submitted:

  • An official document mentioning the company’s name, capital, objects, location of operation, list of directors and authorized signatories, and financial records for the previous three years.
  • The total number of shareholders, their countries, and the number of shares they own.
  • Office location in Thailand and confirmation of ownership or occupancy of the Representative Office’s office space.
  • Employees’ numbers, names, and salaries
  • Detailed explanation of the following:
    • A business forecast for the following three years
    • The type, size, and intended period of the business
    • The stages of operations
    • The proposed machinery and/or office equipment to be used
    • The impact on the Thai economy: what will the Representative Office add to the Thai economy?
    • An estimation of the spending on fixed assets and operational expenses in Thailand for the first three years, as well as an estimation of the benefits of the Thai economy
    • A plan for the import and transfer of foreign technology and for research and development (if any)
  • A declaration that the applicant, directors, managers, or appointed representative meet the requirements and do not have a forbidden characteristic under section 16 of the Foreign Business Act.
  • A representative can be the authorized signatory in charge of business activities in Thailand. A certificate of appointment, a copy of the chosen representative’s passport, and proof of his or her Thai residence (or evidence of permission to enter Thailand) will be required.
  • A power of attorney to the person representing the applicant during the process (along with a copy of his or her passport, if appropriate). 

After submitting the necessary documents to the Department of Business Development, the Representative Office can commence operations within two weeks in practice. Upon approval, a certificate or registration number is issued to the office.

What are the documents required to obtain a BOI promotion?

As mentioned above, a BOI company is a Thai Limited company that has been awarded a promotion from the BOI. To apply for a BOI promotion, the following documents are required.

As part of the application process, companies must submit application forms relating to the company’s specific business category.

Information required by the BOI includes:

  • The total amount of registered capital and how the company will provide this capital.
  • Detailed information on the company’s project and what they intend to do and how it will bring value to the Thai economy.
  • Employee details e.g. the number of foreign and Thai employees the company anticipates hiring
  • Information regarding the management team’s skills and experience
  • A copy of the passport of the applicant and his resume
  • Estimated earnings and expenses of the company for its initial three years
  • Once the application is submitted, a BOI officer will review it and often ask for complementary information. The BOI Officer notably checks that the numbers input in the business plan match and make economic sense. The back and forth can continue until the BOI officer is satisfied with the complementary answers (from 2 to more than 10 for complex projects with high capital investment).
