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 |
|---|---|
| Taxpayer | THB 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 dependent | THB 60,000 |
| Social Security contributions | Actual amount (max THB 9,000) |
| Provident fund / GPF | Actual (max THB 500,000) |
| Health insurance premium | Up to THB 25,000 |
| Life insurance premium | Up 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 rent | Yes | Lease agreement, receipt |
| Equipment (laptop, camera) | Yes (depreciated) | Invoice, depreciation schedule |
| Internet & phone | Yes (business portion) | Bills, allocation basis |
| Software subscriptions | Yes | Receipts, bank statements |
| Travel to client meetings | Yes | Log, receipts |
| Professional development | Yes | Course certificates, receipts |
| Marketing & advertising | Yes | Invoices, platform statements |
| Accounting & legal fees | Yes | Invoices |
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 – 150,000 | Exempt |
| 150,001 – 300,000 | 5% |
| 300,001 – 500,000 | 10% |
| 500,001 – 750,000 | 15% |
| 750,001 – 1,000,000 | 20% |
| 1,000,001 – 2,000,000 | 25% |
| 2,000,001 – 5,000,000 | 30% |
| Over 5,000,000 | 35% |
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:
- Gross income: THB 600,000
- Standard deduction (50%, capped at 100,000): THB 100,000
- Personal allowance: THB 60,000
- Social Security: THB 9,000 (estimated)
- Health insurance: THB 15,000
- Net taxable income: 600,000 – 100,000 – 60,000 – 9,000 – 15,000 = THB 416,000
- Tax: 0 on first 150,000 + 5% on 150,000 (THB 7,500) + 10% on 116,000 (THB 11,600) = THB 19,100
- 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.
