FAQ
Frequently asked questions
How many years of tax exemption does BOI grant?
It depends on the activity tier: A1 (advanced technology) up to 13 years, A2–A4 progressively less, and tier B receives no tax holiday but other rights such as 100% ownership and machinery import duty exemption. Check the latest BOI announcements when planning.
Can service businesses apply for BOI?
Some can — software, digital services, international headquarters (IHQ), and R&D, for example. The activity must be on the promoted list and meet specific criteria such as minimum personnel spending.
Must the company exist before applying?
You may apply before or after incorporation, but once approved the company must be formed and conditions met within the deadline. Getting the shareholding structure right from the start speeds up post-approval steps.
How does BOI help with work permits?
Promoted companies use the One Stop Service Center, where expert visas and work permits are considered without the usual capital and Thai-employee ratio requirements.
