What are the Thailand income tax rates for 2025?

This calculator uses the latest published Thailand tax brackets and personal allowance for the 2025 tax year, sourced from Revenue Dept — 2025 PIT; SSF 5% capped ฿750/mo.. Enter any gross salary above to see the bracket-by-bracket breakdown, your effective rate, and your marginal rate.

How is take-home pay calculated in Thailand?

We start with your gross salary, apply the Thailand personal allowance and any standard deductions, run the result through the 2025 progressive income tax brackets, then subtract mandatory employee social-security and equivalent contributions. The number left is your annual and monthly net pay.

Does this include social security and other payroll deductions in Thailand?

Yes. The Thailand calculator models employee-side social security, pension, health, and any solidarity or surcharge components that apply to wages. Employer-side contributions are excluded because they don't reduce your take-home pay.

Is the Thailand calculator accurate for my situation?

It's a single-filer wage estimate that uses official 2025 rates. Your actual tax can differ based on filing status, dependants, regional or municipal taxes, salary-sacrifice arrangements, capital gains, and other personal credits. Treat the result as a strong first estimate, not tax advice.

What's the effective tax rate on a ฿100,000 salary in Thailand?

At ฿100,000 gross per year, the model returns an effective tax-and-social-security rate of about 0.0% and a marginal rate of about 0.0% — leaving roughly ฿95,000 as annual take-home. Enter your own salary above for a tailored breakdown.
