Any foreign investor who are interested in investing or setting up a BOI promoted companies should consider the restrictions along with the benefits. One of the main restrictions of setting up a BOI promoted company is the minimum investment requirement.
In general, the minimum capital investment is 1 million Thai Baht for eligible activities approved by BOI. However, in certain industries the capital investment requirement is much higher. For example:
- Activity 2.2.2 Health rehabilitation center: Project must have the minimum investment capital at least 30 million baht (excluding cost of land and working capital).
- Activity 4.2.5 Manufacturing of printed circuit board: The investment capital in machinery (including cost of installation and test run) used in the manufacturing process must not be less than 500 million baht.
As for knowledge-based activities, there may be no minimum investment capital requirement. Instead, the investment is based on the minimum annual salaries expense. For example:
- Activity 8.1 Development of software, digital platform or digital content: The minimum investment capital of each project must not be less than 1,500,000 baht per year calculated on the basis of the expenditure on salaries for Thai information technology personnel additionally employed after applying for investment promotion.

In conclusion, the precise minimum capital investment requirement is dependent on the type of activity of your company. Beside the investment capital requirement, there are requirements such as shareholding structure, value added, acquirement of ISO certification. I recommend all business owner to research about the BOI approval requirements so you have a good understanding before applying for BOI.
