BOI and FBL in Thailand: How to Get 100% Business Ownership in 2026

Processing times for BOI certification and FBL licenses in Thailand have doubled. What used to take 3-4 months just a couple of years ago now stretches into 5-6 months or more in 2026, as the Board of Investment and the Department of Business Development work through a backlog of applications. If you plan to launch a business here, the time to file is now, well ahead of the high season rush.

For foreign entrepreneurs who want to operate in Thailand without a Thai partner, BOI and FBL remain the only legal routes to 100% foreign ownership of a company. The standard 51/49 structure relegates the foreign investor to a minority shareholder role. BOI and FBL change that equation entirely.

Quick Answer

• BOI (Board of Investment) certification grants full foreign company ownership plus corporate tax exemptions of up to 8 years

• FBL (Foreign Business License) allows foreigners to operate in normally restricted sectors: tourism, education, healthcare, IT, and logistics

• Both instruments let investors bypass the 51/49 rule that otherwise requires a Thai partner to hold a controlling stake

• Current processing times have stretched to 5-6 months or longer, up from the previous 3-4 months

• The optimal filing window is April-May 2026, so the business is operational before the high season begins in November

• Investors can open accounts, secure visas, and begin preparatory work while the application is still under review

Key Facts

• BOI tax holiday: exemption from corporate income tax (standard rate 20%) for up to 8 years

• Zero import duties on equipment and raw materials for BOI-approved projects

• Streamlined work permits: BOI fast-tracks visas and work permits for foreign specialists, bypassing standard Ministry of Labour bureaucracy

• Sectors accessible through BOI and FBL but closed to ordinary foreign-owned companies: tourism, education, healthcare, manufacturing, IT, and logistics

• A standard Thai company with 49% foreign participation does not grant full control: the Thai majority shareholder formally holds key decision-making power

• The Board of Investment updates its list of priority sectors annually; for 2026 the focus is on technology, green energy, medical tourism, and the digital economy

• According to industry legal advisors, BOI Promotion can, depending on category, extend tax holidays up to 13 years, alongside land ownership rights for offices and factories and removal of the foreign-to-Thai labor quota requirement

How to Start: Step by Step

1. Identify your business category. Review the BOI list of priority sectors at boi.go.th. FBL suits businesses that fall outside BOI criteria but still require access to protected sectors.

2. Prepare a business plan. BOI requires a detailed project description: investment volume, job creation, technology used, and a Thai staff training plan. Minimum investment thresholds vary by category, so confirm current figures before applying.

3. Gather documentation. You will need incorporation documents, the parent company's financial statements (if applicable), founders' passports, and a detailed project proposal with financial projections. FBL applications also require justification for foreign participation.

4. File in April-May 2026. This is the optimal window: given current review times, approval should arrive by October-November, right before high season begins.

5. Use the waiting period productively. Immediately after filing, open a company bank account, arrange visas for key staff, and begin marketing preparation.

6. Hire a lawyer with BOI/FBL experience. Self-filing is possible, but documentation errors can set the process back by months. A Bangkok-based lawyer specializing in investment licensing typically charges 50,000-150,000 THB for full support.

7. Plan an in-person visit for document signing. Some procedures require your physical presence. If you are already traveling, it is worth combining the trip with site visits and location scouting.

8. Secure approval and register the company. Once BOI approves the application, it issues a promotional certificate. Registration with the Department of Business Development (DBD) and obtaining a tax ID follow.

FAQ

How is BOI different from FBL?

BOI provides not only 100% foreign ownership but also tax incentives: corporate tax exemption for up to 8 years and zero import duties. FBL grants the right to operate in restricted sectors but without tax preferences. BOI suits large investment projects, while FBL fits service and trading companies.

Can I run a business in Thailand without a Thai partner?

Yes. Through a BOI certificate or FBL license, a foreigner can own 100% of shares in a Thai company. Without these instruments, foreign shareholders are capped at 49% under the Foreign Business Act 1999.

How much does obtaining a BOI certificate cost?

There are no government fees for reviewing a BOI application. Costs come from legal support (50,000-150,000 THB), business plan preparation, and company registration. Total launch budget starts from 200,000 THB, excluding the actual business investment.

Which industries are eligible for BOI in 2026?

Priority sectors include IT and digital technology, medical tourism, manufacturing, green energy, biotechnology, electronics, automotive, and logistics. The full list is updated regularly at boi.go.th.

How long does the BOI process take in 2026?

Current data shows the process has grown from 3-4 months to 5-6 months or more. The Board of Investment is dealing with a heavy application backlog, so plan for at least six months.

Can I stay in Thailand while my application is under review?

Yes. After filing, you can remain in the country, open company bank accounts, secure visas for staff, and carry out preparatory business activities.

What does BOI offer beyond tax breaks?

Streamlined work permits for foreign specialists, land ownership rights for industrial projects, and expedited visa processing. BOI effectively functions as a 'one-stop service' for investors.

Is BOI suitable for small businesses?

It depends on the sector. BOI has lowered entry thresholds for IT startups and digital projects. For manufacturing, minimum investment is typically 1 million THB or more. Small service businesses may find FBL a better fit.

What happens if I miss the high season window?

High season (November-March) is critical for tourism and service businesses. Missing one season means losing 5-6 months of peak revenue. For manufacturing and IT companies, seasonality matters far less.

The 2026-2027 high season starts in just a few months. Those who file this spring will be ready to launch by November. Those who wait will lose an entire year. In Thailand, preparing early is not just a saying, it is a business strategy.
