Contribution rates, caps and deadlines for the Social Security Fund and Workmen's Compensation Fund in Thailand.
The Social Security Fund provides coverage to employees in cases of injury, sickness, invalidity and death not caused by employment. Coverage also includes maternity, child allowance (up to 6 years), old-age (≥ 55 years) and unemployment benefits.
Company Directors are not subject to Social Security contributions unless they also hold an employee position.
Contributions are paid monthly by both the employer and the employee:
Employee contribution: ฿875 (deducted from salary)
Employer contribution: ฿875 (paid by company)
Total SSF contribution: ฿1,750 / month
Note: The ฿875 cap is reached at a monthly gross salary of ฿17,500 or above.
The WCF provides compensation to employees injured, sick, or deceased as a result of their work, regardless of date, time or place. This is an employer-only contribution — employees do not contribute.
The annual contribution rate ranges from 0.2% to 1% of total annual wages (capped at ฿240,000 per employee per year), depending on the industrial classification of the business.
Annual contribution: ฿240,000 × 8 × 0.2% = ฿3,840
| Contribution | Deadline |
|---|---|
| Social Security Fund (monthly) | 15th of the following month |
| Workmen's Compensation Fund (annual) | 31 January each year |
| WCF — first year (new employer) | Within 30 days from first hire |
| WCF — actual wage reconciliation | End of February (for previous year wages) |
How the WCF annual cycle works: Each year, the Social Security Office calculates an estimated total wage bill for your company and issues the corresponding WCF contribution amount (KT26K), which you pay in advance by 31 January. The following year, your company must declare the actual total wages paid during the previous year by end of February (KT20K). If actual wages were higher than the estimate, you pay the difference; if lower, you receive a refund — settled by end of March.
BizStep handles the preparation and submission of your SSF contributions and annual WCF reports (KT20K / KT26K) as part of our payroll service.
