Complete Guide to Thai Salary Calculator: Net Pay, Tax & Deductions
Understanding your real take-home pay in Thailand is harder than it looks. A job offer of ฿50,000 a month sounds great — but after personal income tax (ภาษีเงินได้บุคคลธรรมดา), social security (ประกันสังคม), and provident fund (กองทุนสำรองเลี้ยงชีพ) contributions, the number that actually lands in your bank account can be noticeably smaller. Thailand uses a progressive tax system with seven brackets, a personal allowance of ฿60,000, and a range of deduction options that most employees never fully use.
That confusion is exactly why we built the Thai Salary Calculator. It takes your gross salary and instantly computes withholding tax, social security, provident fund contributions, and your final net pay — both monthly and annually. It uses the official 2024 (พ.ศ. 2567) tax brackets so the figures reflect what the Revenue Department actually expects.
Whether you are negotiating a job offer, reviewing your payslip, planning tax-deductible investments like SSF and RMF, or preparing for your annual tax filing (ภงด.91), this guide walks you through everything the calculator does and the concepts behind it.
Why Use a Thai Salary Calculator?
- Know your real take-home pay — Gross salary and net salary are two very different numbers. The calculator shows the gap clearly so you can budget accurately.
- Plan your deductions strategically — Contributions to a Provident Fund, SSF, RMF, and other approved investments can lower your taxable income by up to ฿500,000. See the impact before you commit.
- Understand Thailand's progressive tax — With seven brackets from 0% to 35%, small raises can push you into a higher marginal rate. The calculator shows exactly how much of each baht is taxed.
- Compare job offers fairly — Two offers with the same gross salary can have very different net outcomes depending on benefits, provident fund matching, and allowances.
- Prepare for annual tax filing — Withholding tax on your payslip is only an estimate. The calculator helps you anticipate whether you will get a refund or owe more when you file your yearly return.
- Avoid surprises — No one likes discovering they owe the Revenue Department money in March. Model your year ahead of time and adjust your deductions.

How to Use the Thai Salary Calculator
- Enter your gross salary. Type the amount your employer pays before any deductions, in Thai baht (฿).
- Select the period. Choose whether your input is a monthly or annual figure. The calculator converts between the two automatically.
- Toggle Social Security and Provident Fund. Turn SS on or off, and enter your provident fund contribution percentage (typically 3%–15% of salary).
- Add optional deductions. If you contribute to SSF, RMF, NSF, or other tax-deductible vehicles, enter them to see how they shrink your taxable income.
- Read your results. The calculator displays gross income, personal income tax, social security, provident fund, and net pay — both monthly and annually.
Understanding the Concepts
Thailand's progressive tax brackets
Thailand taxes personal income progressively. The more you earn, the higher the rate on the portion of income that falls into each band — not on your entire salary. For the 2024 tax year (พ.ศ. 2567) the brackets are:
| Annual taxable income (฿) | Rate |
|---|---|
| 0 – 150,000 | 0% |
| 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% |
| 5,000,001 and above | 35% |
Someone earning ฿600,000 a year, for example, pays 0% on the first ฿150,000, 5% on the next ฿150,000, 10% on the next ฿200,000, and 15% on the remaining ฿100,000 — not 15% on the whole amount.
Personal allowance and standard deductions
Every taxpayer receives a personal allowance of ฿60,000. On top of that, employment income qualifies for a standard expense deduction (currently 50% of income, up to ฿100,000). These two deductions alone can take a meaningful slice off your taxable income before anything else is considered.
Social security
Social security in Thailand is a flat 5% of salary, capped at ฿750 per month (or ฿9,000 per year). Both employer and employee contribute, but the calculator focuses on the employee portion — the deduction you see on your payslip.
Provident fund
A provident fund (กองทุนสำรองเลี้ยงชีพ) is a voluntary retirement scheme where the employee contributes between 3% and 15% of salary and the employer typically matches or exceeds that amount. Employee contributions are tax-deductible, which makes the provident fund one of the most effective ways to reduce taxable income while saving for retirement.
Practical Use Cases
To see how all of this comes together, here are three common salary scenarios — an entry-level, mid-level, and senior professional — calculated with social security and a 5% provident fund contribution included.
| Scenario | Gross / month | Income tax / month | Social security | Provident fund (5%) | Net / month |
|---|---|---|---|---|---|
| Entry-level | ฿25,000 | ฿0 | ฿750 | ฿1,250 | ฿23,000 |
| Mid-level | ฿50,000 | ฿1,250 | ฿750 | ฿2,500 | ฿45,500 |
| Senior | ฿120,000 | ฿8,750 | ฿750 | ฿6,000 | ฿104,500 |
Figures are estimates based on 2024 brackets, personal allowance, standard deduction, and the deductions shown. Your actual withholding may vary slightly.
Notice how the senior earner's tax jumps significantly — that is the progressive system at work. Also notice that social security stays at ฿750 for both the mid-level and senior cases, because both are above the contribution cap.
Best Practices
- Verify with your employer. Use the calculator as a planning tool, then confirm the actual numbers against your payslip and withholding tax certificate (หนังสือรับรองการหักภาษี ณ ที่จ่าย).
- Track deductions year-round. Keep receipts and records of SSF, RMF, life insurance, mortgage interest, and other deductible expenses so annual filing is painless.
- Maximize tax-deductible investments. Combined SSF and RMF contributions can reduce your taxable income by up to ฿500,000 and 30% of income — a powerful way to cut your tax bill while building wealth.
- Update annually. Tax brackets, allowances, and SS caps change every few years. Re-run the calculator each tax season with the latest figures.
- Consider non-cash benefits. Health insurance, transport allowances, and bonuses all have different tax treatments. Factor them in when comparing total compensation.
