Thailand Freelancer Tax: Every Deductible Expense You Can Claim

From the 50% standard deduction to actual expenses — here's how Thai freelancers can legally minimize their tax bill.

Thailand offers one of the most generous deduction systems for freelancers in Southeast Asia. You get a 50% standard deduction on top of personal allowances — but you may be able to deduct even more if you track your actual business expenses.

The 50% Standard Deduction

Under Thai tax law, income from hiring of services, contracting, business, commerce, agriculture, industry, transport, or other activities qualifies for a standard deduction of 50% of assessable income, capped at THB 100,000.

For freelancers earning less than THB 200,000 per year from freelance income, the full 50% applies. For higher earners, the maximum standard deduction is THB 100,000.

Example: You earn THB 600,000 from freelance work. Standard deduction = min(50% × 600,000, 100,000) = THB 100,000.

Personal Allowances on Top

In addition to the standard deduction, you can claim these personal allowances:

Allowance Amount
TaxpayerTHB 60,000
Spouse (no income)THB 60,000
Child (each, up to 3)THB 30,000
Parent (over 60, dependent)THB 30,000 each
Disabled dependentTHB 60,000
Social Security contributionsActual amount (max THB 9,000)
Provident fund / GPFActual (max THB 500,000)
Health insurance premiumUp to THB 25,000
Life insurance premiumUp to THB 100,000

Actual Expenses vs Standard Deduction

Instead of the 50% standard deduction, you can choose to deduct actual business expenses if they exceed the standard amount. This requires proper documentation:

Expense Deductible? Documentation
Office rentYesLease agreement, receipt
Equipment (laptop, camera)Yes (depreciated)Invoice, depreciation schedule
Internet & phoneYes (business portion)Bills, allocation basis
Software subscriptionsYesReceipts, bank statements
Travel to client meetingsYesLog, receipts
Professional developmentYesCourse certificates, receipts
Marketing & advertisingYesInvoices, platform statements
Accounting & legal feesYesInvoices

For most freelancers with low overhead, the 50% standard deduction (up to THB 100,000) is more beneficial than tracking actual expenses. But if you have significant business costs — renting office space, buying expensive equipment, or traveling frequently — actual expenses may give you a bigger deduction.

Thai Tax Brackets for Freelancers (2025)

After all deductions and allowances, your net income is taxed at these rates:

Net Income (THB) Tax Rate
0 – 150,000Exempt
150,001 – 300,0005%
300,001 – 500,00010%
500,001 – 750,00015%
750,001 – 1,000,00020%

2,000,001 – 5,000,00030%
Over 5,000,00035%

Filing Deadlines

  • P.N.D. 94 (mid-year): File by end of September for income January–June. This is a half-year estimate.
  • P.N.D. 90 (annual): File by end of March for the full previous year. This is the final assessment.

As a freelancer, you're required to file both P.N.D. 94 and P.N.D. 90. The P.N.D. 94 payment is credited against your final P.N.D. 90 liability.

Example: How Much Tax Does a Thai Freelancer Pay?

Assume a freelance graphic designer in Bangkok earns THB 600,000 per year, is single, and has no other income:

  1. Gross income: THB 600,000
  2. Standard deduction (50%, capped at 100,000): THB 100,000
  3. Personal allowance: THB 60,000
  4. Social Security: THB 9,000 (estimated)
  5. Health insurance: THB 15,000
  6. Net taxable income: 600,000 – 100,000 – 60,000 – 9,000 – 15,000 = THB 416,000
  7. Tax: 0 on first 150,000 + 5% on 150,000 (THB 7,500) + 10% on 116,000 (THB 11,600) = THB 19,100
  8. Effective tax rate: 19,100 / 600,000 = 3.2%

That's remarkably low for someone earning THB 600,000 — thanks to Thailand's generous deduction system.
