How Your Thailand Freelance Tax Is Calculated
The Thailand calculator applies the Revenue Code's rules: 50% standard deduction, personal allowances, and progressive brackets:
Step 1: Apply the 50% Standard Deduction
Assessable Income after deduction = Gross Income × 50% (capped at ฿100,000)
This means if you earn ฿600,000, your assessable income after deduction is ฿500,000 (฿600K minus ฿100K cap). No receipts needed — this is a standard deduction available to all freelancers.
Step 2: Subtract Personal Allowances
Taxable Income = Assessable Income − Personal Allowances
Allowances include: personal allowance (฿60,000), spouse allowance (฿60,000), child allowance (฿30,000 per child, up to 3), and social security contributions. The calculator applies these based on your inputs.
Step 3: Apply Progressive Tax Brackets
Tax = Applied against 8 progressive brackets: 0% up to ฿150,000, 5% up to ฿300,000, 10% up to ฿500,000, 15% up to ฿750,000, 20% up to ฿1,000,000, 25% up to ฿2,000,000, 30% up to ฿5,000,000, 35% above ฿5,000,000.
Thanks to the 50% deduction, many freelancers earning under ฿500,000/year pay minimal or zero tax. The calculator shows your effective tax rate after all deductions are applied.

Thailand Freelancer Tax Guide
How is freelance income taxed in Thailand?
Thailand uses a progressive personal income tax system with 8 brackets (0%–35%). Freelancers get a 50% standard deduction on gross income (capped at ฿100,000) plus personal allowances. This means your effective tax rate is often much lower than the bracket rates suggest.
What allowances can I claim?
You can stack: Personal allowance (฿60,000), Spouse allowance (฿60,000 if your spouse has no income), Child allowance (฿30,000 per child, up to 3), and Social security / insurance contributions. These stack with the standard deduction, which means a freelancer earning ฿30,000/month could have taxable income as low as ฿50,000–100,000 — landing in the 0%–5% bracket.
When is the tax filing deadline?
The annual tax return (P.N.D. 90/91) is due by March 31 of the following year. A mid-year installment (P.N.D. 94) is due by June 30. Late filing carries penalties of 1–2× the tax owed plus interest.
Do I need a tax ID number?
Yes. You need a Thai tax ID to file returns. This is separate from a work permit. Many freelancers operate through a registered company structure with proper work permits and tax registration. If you're a foreigner, consult the Revenue Department for your specific situation.
What's the effective tax rate for most freelancers?
After the 50% deduction and personal allowances, many freelancers earning under ฿500,000/year pay minimal or zero tax. The nominal 15% bracket doesn't reflect the actual rate because deductions reduce taxable income substantially. Use the calculator to see your real effective rate.
What is the 180-day rule in Thailand?
If you spend 180 days or more in Thailand in a calendar year, you're considered a tax resident. This means you're taxed on income earned in Thailand AND foreign income brought into Thailand in the same year. Staying under 180 days generally avoids Thai tax residency.
Can I deduct actual expenses instead of the 50% standard deduction?
Yes, you can choose to itemize actual documented expenses instead of claiming the standard 50% deduction. This is beneficial if your actual business expenses exceed the standard deduction cap. Most freelancers find the standard deduction simpler and more generous.
