Setting Up a Company in Thailand: Legal Requirements and Step-by-Step Guide

Thailand remains one of the most attractive destinations for business investment in Southeast Asia. With a strategic location, developed infrastructure, skilled workforce, and government incentives through the Board of Investment (BOI), both Thai entrepreneurs and foreign investors regularly choose to establish companies here. This guide walks you through the legal requirements and practical steps for setting up a company in Thailand.

Types of Business Entities in Thailand

The most common business structures include the Thai Limited Company (both private and public), the Branch Office of a foreign company, the Representative Office, and registered partnerships (ordinary and limited). For most foreign investors, the Thai Private Limited Company is the preferred structure. It requires a minimum of three shareholders at the time of incorporation, though shares can be consolidated after registration. Public limited companies are required for businesses intending to list on the Stock Exchange of Thailand.

Foreign Business Act and BOI Considerations

The Foreign Business Act B.E. 2542 (1999) restricts foreign nationals from conducting certain business activities in Thailand. A "foreign" company is defined as one where foreign shareholders hold 50% or more of the shares. Businesses falling under Lists 1, 2, or 3 of the Act may need a Foreign Business License (FBL) or operate under BOI privileges. Companies that receive BOI promotion can enjoy significant benefits including permission for majority foreign ownership, corporate income tax exemptions for up to 13 years, permission to own land, and work permit facilitation for foreign employees.

Step-by-Step Company Registration Process

The first step is to reserve the company name with the Department of Business Development (DBD). The name must be unique and not similar to existing registered companies. Up to three name choices can be submitted, and approval typically takes one to two business days.

Next, the promoters must file a Memorandum of Association (MOA) with the DBD. The MOA includes the company name, location of the registered office, business objectives, registered capital, names and addresses of the promoters, and the number of shares each promoter subscribes to. The minimum registered capital is not prescribed by law, but a capitalization of at least 2 million THB is recommended for companies that will employ foreign workers requiring work permits.

A statutory meeting of shareholders must then be held to approve the MOA, elect directors, appoint an auditor, and approve any pre-incorporation contracts. Following the statutory meeting, the directors file the registration documents with the DBD. Upon approval, the company receives its corporate registration certificate and is officially established.

Post-Registration Requirements

After registration, the company must apply for a tax identification number with the Revenue Department, register for VAT if expected annual revenue exceeds 1.8 million THB, register for social security with the Social Security Office within 30 days of hiring the first employee, and open a corporate bank account. If the company employs foreign nationals, it must also apply for work permits through the Department of Employment and ensure proper visa processing.
