2026-01-18Siam Advice FirmBOI Analysis

Category 5.8 is the most relevant BOI category for tech entrepreneurs. Let's explore exactly what it covers and how to qualify.

 

What Category 5.8 Includes

Software Development

  • Custom software solutions
  • Enterprise applications
  • Mobile app development
  • Web application development

 

Digital Platforms

  • SaaS products
  • Marketplace platforms
  • Booking/reservation systems
  • CRM and ERP systems

 

Cloud & Infrastructure

  • Cloud computing services
  • Data center operations
  • Cybersecurity solutions

 

Advanced Technologies

  • AI and machine learning development
  • Blockchain applications
  • IoT solutions
  • Big data analytics

 

Investment Requirements

For Category 5.8, the minimum requirement is typically expressed as salary expenditure rather than capital investment:

  • Minimum: 1.5 million THB annual salary to Thai IT staff
  • Example: 3 developers at 50,000 THB/month = 1.8M THB/year ✓

This makes it accessible for startups and small teams.

 

Benefits Specific to 5.8

  • 8-year corporate tax exemption
  • 100% foreign ownership
  • No 4:1 staff ratio
  • Fast-track work permits

 

Common Pitfall

Revenue from non-promoted activities is taxed normally. If you earn revenue from consulting, training, or non-software services, that portion doesn't receive the exemption.

Careful activity classification from the start is essential.
