The Investment Promotion Act provides for tax and non-tax privileges. Tax privileges include exemption and reduction of corporation income tax to save profits of a company for reinvestment and creation of new projects, and exemption of import duties on machinery and raw materials. Non-tax privileges can be provided in the form of stays and work permits of foreign experts and technicians. To obtain both tax and non-tax privileges, an application for investment promotion and supporting documents must be filed with the Office of the Board of Investment of Thailand and the relevant procedures must be complied with.
