BOI Thailand Interview 2026: 6 Questions You Must Be Ready to Answer

You have submitted your application to Thailand's Board of Investment (BOI), and the interview date has been set. Many applicants treat this meeting as a mere formality. That mistake can cost months of delay or an outright rejection.

The BOI interview is a full defense of your project in front of a panel of 4-6 officers from the investment, technical, and legal departments. The session typically runs from one to two hours. How you answer their questions determines not only whether you receive tax incentives, but also whether you gain the right to operate in Thailand outside the restrictions of the Foreign Business Act.

Quick Answer

• Format: a project presentation followed by Q&A in front of a panel of 4-6 BOI officers

• Duration: 1 to 2 hours, longer for projects above 200 million THB

• BOI's core objective: assess the project's impact on the Thai economy, covering jobs, technology transfer, and exports

• Key benefit of approval: the ability to bypass Foreign Business Act restrictions and secure 100% foreign business ownership

• Tax incentives can include corporate income tax exemption for up to 8 years, depending on the project category

• The decision is made after internal panel review, not during the interview itself

Key Facts

• BOI (Board of Investment) is a Thai government agency established in 1966 to attract foreign investment, headquartered in Bangkok on Vibhavadi Rangsit Road

• Without BOI approval, foreign businesses fall under the restrictions of the Foreign Business Act B.E. 2542 (1999), which prohibits or limits foreign participation in dozens of business categories

• Projects on BOI's promoted activities list can qualify for exemption from import duties on machinery and raw materials

• The threshold for 'large projects' requiring enhanced review starts at 200 million THB (roughly $5.7 million at 2026 exchange rates)

• BOI gives strong preference to projects located outside Bangkok, in designated target provinces, where incentives are substantially higher

• The Thai-to-foreign staffing ratio is a mandatory evaluation criterion: the standard requirement is a minimum of 4 Thai employees per 1 foreign specialist to secure work permits

• Your presentation must include concrete figures: investment size, revenue projections, number of jobs created, and implementation timeline

For context on the broader legal landscape foreign investors navigate in Thailand, it is worth noting that outright land ownership remains off-limits to foreigners entirely, which is why structures such as 30-year leasehold registered under Section 540 of the Thai Civil and Commercial Code, paired with separate freehold ownership of the building, are the standard workaround property investors use, a parallel reminder that in Thailand, approval and structure matter as much as capital.

How to Start: Step by Step

1. Identify your project category. Visit the official BOI website (boi.go.th) and review the list of promoted activities. If your business does not fit any category, applying to BOI is pointless. Consider alternative routes such as a Foreign Business License instead

2. Prepare a business plan in English. Required sections: description of the product or service, investment volume, funding sources, 3-5 year revenue projections, a staffing plan with salary details, and a training program for Thai employees

3. Submit your application through the BOI system. Complete the form and attach your business plan, company financial statements (if the entity already exists), and documents proving the source of capital

4. Hire a consultant experienced with BOI applications. This is typically a Bangkok law firm specializing in investment law. A good consultant will help tailor your presentation to the panel's expectations and flag common red flags in advance

5. Prepare answers to 6 key questions:

• What goods or services will you provide, and who are your customers?
• Why is foreign ownership of this business specifically necessary?
• How will the project benefit the Thai economy (jobs, exports, technology)?
• Where does the capital come from, and what are realistic financial projections?
• What is the hiring plan: how many Thai staff, how many foreign staff, at what salaries?
• What technology will be transferred to Thai personnel?

6. Rehearse your presentation. Keep it to 15-20 minutes. Most of the meeting will be devoted to questions, and while you cannot prepare for every one, you can rehearse responses to the standard ones

7. Travel to Bangkok for the meeting. If you are booking accommodation near BOI headquarters, the Chatuchak area is convenient, as the office sits on Vibhavadi Rangsit Road. Arrive 15-20 minutes ahead of your scheduled time

8. Wait for the outcome after the interview. The decision is made during the panel's internal review, not on the spot. The standard timeline is 40 to 90 business days, depending on the scale of the project

FAQ

Can the BOI interview be done remotely?

BOI allows online meetings in certain cases, but for large projects above 200 million THB, in-person attendance is practically mandatory. Officers assess not just your paperwork but your competence in presenting the project.

What language is the interview conducted in?

English. If your business English is not confident enough for a formal presentation, bring an interpreter or consultant who can speak on the project's behalf.

What tax incentives does BOI approval provide?

Depending on the project category and location: corporate income tax exemption for up to 8 years, exemption from import duties on equipment, and streamlined work permits for foreign specialists.

Can BOI approval help with buying real estate?

No. BOI does not handle personal property purchases. The board evaluates business projects, manufacturing, IT, service companies, logistics, and other activities on its approved list.

How much does it cost to apply to BOI?

The application itself is free. Costs arise from document preparation, legal consultation, and travel to Bangkok. Market estimates put the full preparation cycle with a consultant at 100,000 to 300,000 THB.

What happens if BOI rejects the application?

Rejection does not prevent you from doing business in Thailand. You can reapply with a revised project or obtain a Foreign Business License through the Ministry of Commerce, though without the tax incentives.

Do I need a registered Thai company before applying?

No. You can apply before registering a company. However, once approved, you will have a limited window to register the legal entity and begin operations.

Which industries does BOI prioritize in 2026?

Priority sectors include electronics, digital technology, bioeconomy, medical tourism, automation, electric vehicles and charging infrastructure, and data centers. The full list is updated regularly on boi.go.th.

The BOI interview is the moment your project either gains or loses its competitive edge in the Thai market. Prepare your numbers, rehearse your answers, and demonstrate genuine value for Thailand's economy. The panel rewards specifics, not ambitious promises.
