On December 12, 2025, Thailand’s Ministry of Labor published a ministerial regulation prescribing the minimum and maximum wages used as a base for calculating social security contributions. The regulation, which takes effect on January 1, 2026, sets a flat minimum base wage of THB 1,650 per month and a phased increase of the maximum base wage over the following six years, as outlined in the table below. Impact on Social Security Benefits Not only will monthly contributions increase as a result of the adjustment to the maximum wages used as a base for calculating social security contributions, but the maximum benefits available to insured persons will also be enhanced, as shown in the next table. Employer Obligations From January 1, 2026, employers must correctly withhold wages and remit social security contributions for both the employer’s and employees’ portions in compliance with the revised thresholds. Failure to comply may expose employers to penalties under the Social Security Act B.E. 2533 (1990). Employers should ensure that payroll systems are updated as necessary to reflect these changes to the wage ceiling used for social security contribution calculations.

Thailand has amended the Labor Protection Act to significantly expand family leave benefits and strengthen employment protections, effective December 7, 2025. The Labor Protection Act (No. 9) B.E. 2568 (2025), published in the Government Gazette on November 7, 2025, provides enhanced maternity and paternity benefits, introduces new childcare leave provisions, and extends labor protections to certain public sector contractors.

This leave requires a medical certificate and is compensated at 50% of the employee’s regular wage. New Paternity Leave Male employees are now entitled to 15 days of paid paternity leave to support their spouse or partner during childbirth. This new leave allowance may be taken before or within 90 days after childbirth, with employers required to pay full wages for all 15 days. Protection for Public Sector Contractors The law extends protection to individuals engaged under service contracts with government agencies, including central, regional, and local administrations, state enterprises, and public organizations. When such workers are supervised or controlled in a manner similar to employees, the contracting government agencies must provide them with rights and benefits equivalent to those under the Labor Protection Act, including remuneration, weekly holidays, public holidays, annual leave, sick leave, regulated working hours, and rest periods.
