Isn’t the maximum Thai social security contribution ฿750 a month?

It was — for thirty years. The §33 wage ceiling was frozen at ฿15,000/month from 1995 through 2025, making the 5% employee maximum ฿750. From 1 Jan 2026 the ceiling is ฿17,500 (maximum ฿875), rising to ฿20,000 in 2029 (฿1,000) and ฿23,000 in 2032 (฿1,150). Any answer of ฿750 — from an AI, a payroll article, or an old HR memo — is out of date.

Does my employer pay more too?

Yes. Under §33 the employer matches your 5% on the same capped wage, and the government adds 2.75%. At the 2026 ceiling that is ฿875 from you, ฿875 from your employer, and ฿481.25 from the state each month.

I earn well above the ceiling — what is my real contribution rate?

Lower than 5%. You contribute 5% of the capped wage, not your full salary — at ฿30,000/month in 2026 that is ฿875, an effective 2.9%. The mirror image: your SSO benefits, including the old-age pension, are computed on the capped wage too.

Did the 2026 change affect Section 39 or Section 40?

No. §39 stays a flat ฿432/month (9% of a base frozen at ฿4,800 since the scheme began), and §40’s ฿70/฿100/฿300 options are unchanged. Only the §33 employee ceiling was unfrozen.

Why is my payslip showing less than 5% right now?

Two possibilities: your wage is above the ceiling (you pay 5% of the cap, not your wage), or your employer is registered in one of the 9 southern flood-relief provinces where a temporary measure cuts the rate to 3% from Dec 2025 to May 2026. Everywhere else the standard 5% applies.

Thailand Social Security Contribution (2026 ceiling unfreeze)

Computes your Thai Social Security Office (SSO) contribution for Section 33 (employees), Section 39 (voluntary ex-employees), or Section 40 (informal workers). The Section 33 wage ceiling was frozen at ฿15,000/month from 1995 until the Royal Gazette announcement of 12 Dec 2025 raised it to ฿17,500 from 1 Jan 2026 — so the maximum employee contribution jumps from ฿750 to ฿875, with further phases to ฿20,000 (2029) and ฿23,000 (2032). Thirty years of the old number mean general AI and much of the Thai web still answer ฿750; this tool uses the phased schedule, and knows §39 stays on its frozen ฿4,800 base.

실무자의 해석

알아둘 점

The ฿15,000 ceiling stood for 30 YEARS (1995–2025), so “maximum contribution ฿750” is burned into every AI model and half the Thai web. From 1 Jan 2026 the ceiling is ฿17,500 — maximum ฿875/month — rising to ฿20,000 in 2029 (฿1,000) and ฿23,000 in 2032 (฿1,150). This calculation already uses the 2026–2028 (฿17,500) ceiling.

좋은 신호

At ฿30,000 you only contribute on the ฿17,500 ceiling — an effective rate of 2.9% of your actual wage, not 5%. The flip side: your benefits are computed on the capped wage too, so the cap that saves you money now also caps your pension later.

좋은 신호

The higher ceiling is not just a bigger deduction — SSO benefits are keyed to the capped wage. The old-age pension is a percentage of your average (capped) wage over the last 60 months, so contributing on ฿17,500 instead of ฿15,000 raises the wage your pension is computed from. For anyone earning above the old cap, the unfreeze is a benefits raise wearing a deduction’s clothes.

알아둘 점

Footnote: a temporary relief measure cuts the 5% rate to 3% from Dec 2025 to May 2026 in 9 flood-hit southern provinces only. If your employer is registered there, your slip will show less than this calculation for those months — everywhere else, the standard 5% applies.

알아둘 점

This computes the statutory SSO contribution only — it is not advice on which section or option to choose. §33 employee contributions are also deductible for personal income tax, and moving between sections (e.g. §33 → §39 within 6 months of leaving a job) has its own deadlines worth checking with the SSO.

Section 33 (employees): employee and employer each contribute 5% of the monthly wage, and the government adds 2.75%, with the wage clamped between the ฿1,650 floor and the ceiling. The ceiling was ฿15,000 from 1995 through 2025; the Royal Gazette announcement of 12 Dec 2025 raises it to ฿17,500 from 1 Jan 2026, ฿20,000 from 2029, and ฿23,000 from 2032 — maximum employee contributions of ฿875, ฿1,000, and ฿1,150 respectively.

Section 39 (voluntary continuation after leaving employment): a flat ฿432/month — 9% of a fixed ฿4,800 base that has never been updated and was not changed by the 2026 reform. There is no employer or government share on §39 in this tool’s scope.

Section 40 (informal workers): flat monthly options — ฿70 (option 1), ฿100 (option 2), or ฿300 (option 3) — buying successively more benefit branches. Unchanged by the reform.

The year selector picks the phase ceiling only; it does not prorate within a year. The temporary 3% rate (Dec 2025 – May 2026, 9 southern flood-relief provinces) is surfaced as an insight, not a compute path — it is regional, temporary, and employer-registration-dependent.

Benefits context: SSO old-age pension is computed as a percentage of the average capped wage over the final 60 months of contributions, so the ceiling directly bounds the pension base. This tool computes contributions, not benefits.
