Money-Saving Tips
BOI Zone 3 (outside Bangkok) offers maximum incentives — up to 13 years corporate tax exemption.
Combine BOI promotion with EEC (Eastern Economic Corridor) incentives for additional benefits.
BOI promotion allows majority foreign ownership — avoiding the need for Thai majority shareholders.
Apply for multiple activities under one BOI certificate to reduce per-activity costs.
BOI incentives and fees are subject to change. Actual investment requirements depend on the specific promoted activity. Consult a BOI-certified consultant.
