BOI promotion
BOI-promoted companies can receive corporate tax holidays, import duty exemptions, 100% foreign ownership, land ownership and easier work permits. We check eligibility, prepare the application and handle the reporting afterwards.
Foreign Investment / BOI
Own and control your business in Thailand, legally
The Foreign Business Act limits foreign ownership in many activities. We find the legal route for yours (BOI promotion, a Foreign Business Licence or the Treaty of Amity) and take you through it.
This is for you if
- Your activity is on List 2 or List 3 of the Foreign Business Act and you want majority ownership
- You are considering BOI promotion for tax incentives, land ownership or foreign staff
- You are an American company or citizen and want to use the Treaty of Amity
- You want a representative or regional office, a joint venture or an acquisition
From THB 20,000Prices exclude 7% VAT and government fees.
Start with the right route, not the first one
Most foreign investors are told to use a Thai nominee to hold 51% of the shares. It is illegal, and the authorities actively check nominee structures. There are legal alternatives, and the right one depends on your activity, your nationality, your capital and your plans.
We test the options in order (BOI promotion, Treaty of Amity, Foreign Business Licence, office structures) and recommend the one that gives you control with the least cost and delay.
What we do for you
Foreign Business Licence
For majority foreign-owned companies in List 2 or List 3 activities. We build the file the Foreign Business Committee expects: business plan, economic benefits, capital and staffing.
US-Thai Treaty of Amity
American citizens and US companies can own a majority or all of a Thai company in most activities. We handle the certification with the US Embassy and the Ministry of Commerce.
Representative and regional offices
For market research, quality control or support to the head office, without revenue in Thailand. We register the office and keep it compliant.
Joint ventures
We structure and draft joint venture agreements, from project collaborations to joint venture companies, combining international practice with Thai law.
Mergers and acquisitions
From identifying the target to due diligence, negotiation and closing, with the tax structure reviewed before you sign.

Frequently asked questions
BOI, Foreign Business Licence or Treaty of Amity: which one do I need?
It depends on your activity and nationality. BOI promotion suits promoted industries and larger investments; the Treaty of Amity is only for US citizens and companies; the Foreign Business Licence is the route for other restricted activities. We check the three in that order.
How long does a Foreign Business Licence take?
Typically 60 to 90 days for List 3 activities, which the Director-General approves after the Foreign Business Committee. List 2 activities need Cabinet approval and take 6 to 12 months.
Is using a Thai nominee shareholder allowed?
No. Holding shares on behalf of a foreigner to get around the Foreign Business Act is a criminal offence for both the nominee and the foreigner. We help you move to a legal structure if you already have one.
