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.

Similar to other types of corporate disputes, tax-related conflicts often begin with an earnest attempt to resolve matters outside the courtroom. The prospect of engaging in tax litigation can be daunting, given the potential strain on commercial relationships, the legal expenses, and the uncertainty surrounding its resolution. However, there are instances when tax litigation becomes the sole avenue for seeking redress. For individuals and entities contemplating the pursuit of tax-related legal remedies, the Thai legal system offers an accessible, impartial, and equitable platform for dispute resolution. Tilleke & Gibbins’ latest update to Tax Litigation in Thailand provides an outline for navigating tax-related disputes within the Thai legal framework. It aims to equip readers with a fundamental understanding of procedures and practices within the Thai tax litigation landscape. The full guide is available through the button below.

Cross-border disputes often end with a judgment or arbitral award issued outside Thailand. When a party has assets or operations in Thailand, the key question becomes simple: will a Thai court enforce it? Thai law treats foreign court judgments and foreign arbitral awards very differently. Foreign court judgments cannot be recognized or enforced directly and must effectively be re-litigated. Foreign arbitral awards, however, benefit from a clear recognition and enforcement process under the New York Convention and Thailand’s Arbitration Act. Thailand’s Overall Approach Thailand does not have a general law or treaty that allows automatic enforcement of foreign court judgments. To rely on a foreign judgment, a party must initiate a new lawsuit in a Thai court, plead the claim under Thai law, and prove the case again. The foreign judgment can be used as evidence, but it is not binding, and the Thai court retains full discretion to reassess both the facts and the law. Foreign arbitral awards are treated more favorably. Thailand is a longstanding member of the New York Convention and has implemented it through the Arbitration Act. The act provides a straightforward process for asking a Thai court to recognize and enforce a qualifying award, without retrying the dispute, and subject only to limited refusal grounds. Foreign Court Judgments: Persuasive but Not Binding Although Thai courts do not recognize or enforce foreign court judgments, they may rely on them as persuasive evidence under certain conditions. Courts generally give more weight to judgments that are final on the merits, issued by a court with proper jurisdiction, and reached after proper notice and an opportunity for the defendant to be heard. Default judgments or rulings based primarily on procedural grounds carry less weight, and the ultimate relevance and weight are left to the court’s discretion. In practical

As Thailand transitions into an aged society, retirement policy and workplace protections for older workers have come into sharper focus. With public sentiment increasingly open to working beyond the traditional retirement age, questions about employee rights and employer obligations are more relevant than ever. In October 2025, Prime Minister Anutin Charnvirakul proposed increasing the statutory retirement age to 65 for government officers, citing Thailand’s aged-society status and the potential social and economic benefits of longer working lives. While academics and stakeholders have raised concerns about systemic impacts, public opinion remains divided, with many workers signaling a willingness to continue working beyond the current norm. Against this backdrop, it’s worth revisiting what the Labor Protection Act B.E. 2541 (1998) (LPA) requires in regard to retirement and severance pay. This article explains the current legal landscape under the LPA, with a focus on retirement and severance pay for employees over 60, recent judicial developments, and practical options for structuring postretirement engagements. Retirement as Termination Under the LPA Under the LPA, retirement—whether set by agreement between employer and employee or unilaterally stipulated by the employer—is deemed a termination of employment. As a result, employees who retire under such terms are entitled to severance pay. The law also adds a default rule: if there is no agreed or prescribed retirement age, or if the prescribed retirement age exceeds 60, an employee aged 60 or older may declare an intention to retire. The declaration takes effect 30 days after notice, and the employer must pay severance accordingly. In short, retirement triggered by agreement, the employer’s work rules, or an employee’s valid notice is treated as a termination, and statutory severance pay is owed. Hiring or Rehiring Employees Over 60 Practical issues arise when an employer’s work rules set a retirement age that does not
