When starting a company in Thailand, you should consider setting up one in the special economic zones around the country, as investors will be entitled to a vast range of incentives. We have put together a guide on understanding special economic zones in Thailand.
Let’s find out more in-dept information about special economic zones.
What are the special economic zones?
Special economic zones (SEZs) are special areas that support trade and investment opportunities across the borders of Thailand.
Investing in SEZs also provide investors with tax and non-tax incentives, one-stop service provisions, access to foreign workers and infrastructure development.
The SEZs in Thailand are located at the border of neighbouring countries: Tak and Kanchanaburi border Myanmar; Chiang Rai, Mukdahan, Nong Khai and Nakhon Phanom border the People’s Republic of Laos; Sa Kaeo and Trat border Cambodia; and Songkhla and Narathiwat border Malaysia.
Provinces situated near the borders will be able to access natural resources and cross-border trade routes between Thailand and neighbouring countries.
