BOI in Thailand: Benefits and How It Differs from SMEs

If you’re just starting a business in Thailand, understanding the BOI can give you a real competitive edge over a standard company. Here’s a clear look at what the BOI is, the privileges it offers, and how it compares to running an ordinary SME — so you can decide whether it’s the right path for you.

What Is the BOI?

The BOI (Board of Investment) is Thailand’s investment promotion agency. Its core role is to support and encourage investment for businesses under its scheme, helping them build capability and compete more effectively within Thailand. The BOI reduces start-up risk and lowers initial investment costs, helps businesses reach profitability sooner, and provides advisory and support services across the investment process. The broader aim is to stimulate the economy and develop the country sustainably — and when foreign investors see those opportunities, they’re more likely to invest here. To join the scheme, a business must meet the BOI’s specific eligibility criteria.

8 Business Categories the BOI Promotes

Agriculture and agricultural products (e.g. processed starch, medical-grade food); light industry (e.g. textiles, medical instruments); minerals, ceramics and base metals (e.g. glass, ceramics, construction materials); electrical appliances and electronics; metal products, transport equipment and machinery; chemicals, paper and plastics; services and public utilities; and technology and innovation development.

5 Target Industry Groups

Agriculture, medical and biotechnology industries; high-technology industries; basic and supporting industries; digital, creative and high-value-added service industries; and research, development, and targeted technology development.

Privileges for BOI-Promoted Businesses

Tax benefits:

  • Corporate income tax exemption of up to 13 years (depending on conditions and business type)
  • A 50% reduction in corporate income tax for 5 years (in designated investment promotion zones)
  • Exemption or reduction of import duties on machinery and raw materials
  • Exemption of import duties on items for research and development

Non-tax benefits:

  • 100% foreign ownership permitted (excluding businesses restricted by other specific laws)
  • The right to own land
  • Permission for skilled foreign specialists and technicians to work in Thailand
  • The ability for family members and dependents of foreign staff (parents, spouse, children) to reside in Thailand
  • Permission for foreign nationals to remit funds abroad

As you can see, operating under the BOI offers meaningfully more advantages than running a standard SME — particularly on the tax side, with substantial exemptions and reductions. That said, if you’re interested, you’ll need to pass the BOI’s assessment and run your operation in line with all the required conditions.
