Social security contribution changes
Impact date: 1 January 2026 onwards The maximum monthly contribution per party (employer and employee) have been updated as follows:
- from 2026 – 2028, THB 875 (based on a maximum salary of THB 17,500)
- from 2029 - 2031: THB 1,000 (based on a maximum salary of THB 20,000)
- from 2032 onwards: THB 1,150 (based on a maximum salary of THB 23,000)
Employer implications/action needed Employers should update payroll systems to apply the new maximum salary base of THB 17,500, resulting in a maximum monthly contribution of THB 875 for both employer and employee, and ensure monthly SSO filings use the correct new ceiling.
Employer risk Underpaid or late contributions (i.e. filed after the 15th of the following month) attract a 2% monthly surcharge on outstanding amounts. An employer’s property may also be seized and auctioned to recover unpaid contributions.

Employee Welfare Fund
Impact date: 1 October 2026 In November 2024, Thailand issued a series of regulations implementing the Employee Welfare Fund (Fund). The Fund provides financial support to employees in cases of resignation, termination (regardless of any clauses) or death. The Fund will not apply if employers provide employees with a provident fund or an equivalent employee welfare fund managed by the employer.
Although originally intended to be effective from 1 October 2025, it has been deferred to 1 October 2026.
Employer implications/action needed From 1 October 2026 onwards, employers who employ 10 or more employees and who do not provide employees with a provident fund or an equivalent employee welfare fund are required to:
1. register employees with the Fund
2. deduct 0.25% from the employee’s wages and remit it to the Fund and
3. contribute 0.25% of the employee’s wages to the Fund
The deduction of employee’s wages (item 2.) and the employer’s contribution (item 3.) must be made on a monthly basis and remitted to the Fund by the 15th of the following month.
Employer risk Employers failing to remit the savings or contributions to the Fund by the 15th of the following month shall be subject to a late payment penalty, amounting to a 5% monthly surcharge. Employers failing to submit the required forms, notify changes or provide false information shall be subject to no more than 6-month imprisonment or a fine not exceeding THB 10,000 or both.
