Thailand Adjusts Income Tax Exemption for Severance Pay

On July 17, 2024, Thailand issued the Ministerial Regulation under the Revenue Code regarding Revenue Tax No. 394 (B.E. 2567) to increase the personal income tax exemption amount on severance pay for terminated employees.

Under this ministerial regulation, terminated employees are exempt from personal income tax on their severance pay up to a severance pay amount equivalent to their last 400 days’ wages, capped at THB 600,000. This tax exemption does not apply to severance pay relating to retirement or the expiration of a fixed-term employment agreement.

Previously, this exemption, which has been in effect since 1998, only applied to an amount equivalent to their last 300 days’ wages, capped at THB 300,000. This aligned with the maximum severance pay rate specified in the Labour Protection Act B.E. 2541 (LPA). However, when the LPA was amended in 2019, the maximum severance pay rate was increased from a rate equal to employees’ last 300 days’ wages for those who have worked for 10 years or more, to a rate equal to employees’ last 400 days’ wages for those who have worked for 20 years or more. The recent ministerial regulation was enacted accordingly to align with the updated severance pay rate and account for Thailand’s rising inflation rate.

The new exemption rate applies to assessable income received from January 1, 2023, onward. For any excess severance pay withheld in 2023 and filed in 2024, individuals may request a tax refund from the Revenue Department, according to Revenue Department clarification. This should be done according to the applicable procedure within three years of the income tax return filing deadline.

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.

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
