Weekly Recap: Tax Fundamentals Mastered

This week we covered the foundational tax concepts every foreign investor needs. Here's your complete reference guide.

 

Key Concepts Covered

Tax Years (Day 3)

• Personal tax: Always calendar year (Jan 1 - Dec 31)
• Corporate tax: Choose calendar or fiscal year
• Recommendation: Calendar year for simplicity

 

CIT vs. PIT (Day 4)

• CIT: Company pays 20% on net profits
• PIT: You pay 0-37% on personal income
• Reality: Often taxed twice (company + personal level)

 

Dividend Withholding (Day 5)

• Rate: 10% on dividend distributions
• Impact: Reduces take-home from company profits
• Total effective tax: 28% (20% CIT + 10% withholding)

 

Service Withholding (Day 6)

• Rate: 15% on payments to foreign entities
• Applies to: Consulting, royalties, interest
• Treaty benefits: Can reduce to 10% or lower

 

Double Taxation Treaties (Day 7-8)

• Purpose: Prevent being taxed twice on same income
• Methods: Exemption or foreign tax credit
• Requirement: Must file documentation to claim benefits

 

The Tax Layers

As a foreign business owner, you face:

Layer 1: Corporate Income Tax

• 20% on company profits (0% with BOI)

Layer 2: Dividend Withholding

• 10% when taking profits out

Layer 3: Personal Income Tax

• 0-37% on salary and other personal income

Layer 4: VAT

• 7% on sales (if revenue > 1.8M THB)

 

Key Takeaways

1. Structure Matters

Your choice of salary vs. dividend significantly impacts total tax burden.

 

2. BOI is Powerful

Eliminating the 20% CIT layer saves millions over time.

 

3. Treaties Help

If you're from a treaty country, claim the benefits—they're substantial.

 

4. Documentation is Essential

All tax benefits require proper filing and documentation.
