How this is calculated
Your monthly salary is annualized, the standard expense deduction and personal/spouse/child allowances and your social security contribution are subtracted, Thailand’s progressive tax brackets are applied, and social security is then also taken off pay as a payroll item — the same engine behind the full Income Tax Calculator, minus the optional deduction fields.
Take-home pay at a glance (2026)
Three worked examples from the calculator above, for a single employee with no children and no optional deductions. Social security is ฿875 a month at every level shown because the contribution is capped at a ฿17,500 wage.
| Gross salary / month | Income tax / year | Social security / month | Take-home / month |
|---|---|---|---|
| ฿30,000 | ฿1,975 | ฿875 | ฿28,960 |
| ฿50,000 | ฿20,450 | ฿875 | ฿47,421 |
| ฿100,000 | ฿122,375 | ฿875 | ฿88,927 |
Bonuses and part-year employment
A bonus is ordinary assessable income in the year it’s paid: it is added to your annual total and can push part of it into a higher bracket, so the tax on a bonus is usually more than your effective rate suggests. The Bonus Calculator works that out from your salary and bonus together.
If you start or stop work part-way through a year, your real annual income is less than twelve months of salary, so your actual tax is lower than this calculator’s full-year estimate. Thai employers withhold each month as if you will earn the full year, which is why part-year employees often overpay and get the difference back when they file — the Tax Refund Estimator estimates that refund.

Frequently asked questions
How is this different from the Income Tax Calculator?
Same underlying tax math, but this is the quick version — just salary, spouse, and children. The full Income Tax Calculator also covers insurance, RMF/TESG, and home loan interest deductions, plus a bracket-by-bracket breakdown.
What tax year does this use?
The 2026 personal income tax brackets and standard allowances.
Is social security included in the deduction?
Yes, in both places it belongs. It's shown as its own line because it's a payroll deduction that reduces your take-home pay, and it's also subtracted from your assessable income as an allowance before income tax is calculated — the same treatment as on a Thai tax return, so the tax line already reflects it.
