The most typical business structure chosen by foreign investors is a private limited company. The following table shows five easy steps to set up a company in Thailand.
STEP 1: Reserve your business name. To begin, reserve your company name on the DBD website; once approved, it will be valid for 30 days. Reserve your company name at Reserve DBD.
STEP 2: File the Memorandum of Association (MOA). The MOA is a legal document which the company’s founder is required to submit to the DBD. It contains information such as the company’s goals and objectives.
STEP 3: Set up a statutory meeting. A statutory meeting requires the attendance of all company founders and shareholders to decide and pay for the company’s registered capital and discuss the articles of association (AOA).
STEP 4: Submit a registration application. A registration application must be submitted either online or in person at a DBD office to show that you have completed the legislative requirements. You will then receive a business certificate confirming your company’s registration.
STEP 5: Register for corporate income tax (CIT) and value-added tax (VAT). After your company has been registered, you must apply for and receive a company corporate tax ID card from the Revenue Department within 60 days. Companies are required to pay corporate income tax (CIT) and file tax filings, according to the Revenue Department.
While the above five-step process is to set up a private limited company, other types of companies require slightly different procedures.
1. Sole proprietorship and non-registered ordinary partnership: Do not require official registration.
2. Registered ordinary partnership and limited partnership: Skip step 2 and step 3 and simply submit the registration application to the DBD office in the area where the company is located.
3. Public company limited: Requires extra documents authorized by the SEC in step 2 onwards.
Note: The application is only available in the Thai language, advice from a law firm or other qualified professional is recommended.
