Published: April 15, 2024

This article is for informational purposes only and is based on publicly available Thai Revenue Department guidance and the Revenue Code. Tax rules change — verify current regulations at rd.go.th or consult a licensed Thai tax advisor before making financial decisions.

Freelancing in Thailand

Whether you're a digital nomad, consultant, or independent professional, understanding your tax obligations is essential for compliance and financial planning.

For the broader 2026 system this guide fits into — brackets, residency, foreign income, and filing — see Thailand Personal Income Tax 2026: The Complete Overview.

Income Categories for Freelancers

Thai tax law classifies income into categories under Section 40 of the Revenue Code. As a freelancer, your income likely falls under one of these:

Section 40(2) - Employment-like Services

  • Contract work resembling employment
  • Fees for services with specific deliverables

Section 40(6) - Liberal Professions

  • Doctors, lawyers, accountants, engineers
  • Architects, artists, and performers
  • Flat-rate deduction: 30% (up to 60% for certain professions)

Section 40(7) - Contractors

  • Construction and installation work
  • Project-based technical services
  • Flat-rate deduction: 40%

Section 40(8) - Business Income

  • Trading, selling goods
  • General services and consulting
  • Flat-rate deduction: 60%

Expense Deductions

You have two options for expense deductions:

Flat-Rate Method

  • Simple, no documentation required
  • Fixed percentage based on income type
  • Best for those with low actual expenses

Actual Expense Method

  • Requires detailed records and receipts
  • Better if actual expenses exceed flat rate
  • Must maintain proper accounting

Filing Requirements

PND90 (Annual Return)

  • Due by March 31 (or April 8 online)
  • Required if income exceeds 60,000 THB (single) or 120,000 THB (married)

PND94 (Mid-Year Return)

  • Due by September 30
  • Required for income received January-June exceeding thresholds
  • Acts as prepayment toward annual tax

Tips for Freelancers

  1. Track Everything: Keep receipts and records for all business expenses
  2. Set Aside Tax Money: Reserve 10-20% of income for taxes
  3. Understand Withholding: Clients may withhold 3% tax at source
  4. Consider Registration: Formal business registration may offer benefits
