Thailand Proposes Amendments to the Social Security Act: Expanding Coverage and Enhancing Benefits for Insured Persons
Introduction
On 3 November 2026, the Cabinet approved the draft Social Security Act (No. ..) B.E. …. (the “Draft Bill”), as proposed by the Ministry of Labor and revised from the version previously reviewed by the Office of the Council of State. The Draft Bill seeks to amend the Social Security Act B.E. 2533 (1990) (the “Social Security Act”) in order to modernize Thailand’s social security framework in response to current economic and demographic conditions, particularly the country’s ageing population.
The Draft Bill proposes amendments in the following key areas.
1. Governance and Administration of the Social Security Fund
- Social Security Committee: Empowers the Committee to issue regulations governing the write-off of bad debts, and introduces an additional disqualification that prevents members appointed by the Minister from simultaneously serving on the Workmen’s Compensation Fund Committee.
- Medical Committee: Extends the qualifications and disqualifications applicable to the Social Security Committee to members of the Medical Committee.
- Term of Office: Changes the term of the Social Security Committee, its advisers and the Medical Committee from two years (with the possibility of reappointment for up to two consecutive terms) to a single term of three years.
- Audit Committee: Clarifies its composition, qualifications and responsibilities, including the preparation of an audit charter and the review of internal controls, risk management and good governance.
- Appeal Committee: Revises the relevant provisions to provide greater clarity.
2. Social Security Fund Revenue
The Draft Bill revises the sources of revenue of the Social Security Fund to accommodate the introduction of Section 39/1 and the revised provisions on excess contributions and unclaimed benefits. The proposed sources include:
- Contributions from the Government, employers and insured persons under Sections 39/1, 40 and 46; and
- Excess contributions, surplus proceeds from the seizure, attachment or auction of assets, outstanding payments due to insured persons, and unclaimed benefits for which no refund has been requested.
3. Insured Persons under Section 33
- Maximum Age: Raises the upper age limit for compulsory insurance of employees from 60 to 65 years, or to such other age as may be prescribed by Royal Decree.
- Wage Base: Requires the minimum and maximum wage bases used to calculate contributions to be reviewed at least once every five years.
- Child Allowance: Allows eligible insured persons to continue receiving child allowance for six months after their employment ends. This period may be extended by Royal Decree, but may not exceed 12 months.
4. Continued Insurance under Section 39
- Increases the minimum contribution period required for former Section 33 insured persons to apply for continued insurance from 12 to 24 months.
- Requires eligible persons to notify the Social Security Office (the “SSO”) within six months from the date their Section 33 insured status ends.
- Imposes a surcharge of 2% per month on unpaid or underpaid contributions, capped at the amount of contributions payable.
5. New Section 39/1: Continued Coverage for Old-Age Pension Recipients
The Draft Bill introduces Section 39/1, which allows certain persons who have ceased to be insured under Section 33 or Section 39 and are entitled to an old-age pension to continue their social security coverage.
- Eligibility and Notification: Eligible persons may elect to continue coverage by notifying the SSO within six months from the date their insured status ends, while retaining their old-age pension entitlement.
- Contributions: The Government will contribute one part for every two parts contributed by the insured person, at the rates prescribed by Ministerial Regulation.
- Coverage: Continued coverage will provide benefits in respect of sickness or injury, disability and death. These rights will be non-transferable and not subject to execution.
6. Contribution Payments and Refunds
The Draft Bill clarifies employers’ obligations regarding contribution payments and revises the procedures for recovering excess contributions and surplus proceeds, as follows:
- Contribution Payments: Employers must deduct the insured person’s share of contributions from wages and submit both the employer’s and the insured person’s contributions, together with the prescribed form, to the SSO by the 15th day of the following month.
- Failure to Pay Contributions: Where an employer fails to submit contributions or submits an insufficient amount, an officer may issue a written notice requiring payment of the outstanding contributions and surcharge within a period of not less than 30 days from receipt of the notice.
- Excess Contributions under Section 33: Employers may offset excess contributions against contributions payable in the following period. Alternatively, employers, insured persons or other entitled persons may request a refund within one year from notification by the SSO.
- Excess Contributions under Sections 39 and 39/1: Insured persons may offset excess contributions against subsequent contributions or request a refund within one year from notification by the SSO.
- Surplus Auction Proceeds: Any surplus remaining after deduction of enforcement expenses, outstanding contributions and surcharges must be returned to the employer or other entitled person. The SSO must notify the entitled person to claim the amount within one year.
- Unclaimed Amounts: If an amount remains unclaimed three years after notification, the SSO must deposit it into a designated account. If it remains unclaimed after ten years, it will be transferred to the Social Security Fund as Fund revenue. The entitled person may subsequently claim the amount, together with the interest earned on the bank deposit.
7. Maternity and Disability Benefits
- Maternity Benefits: Extends the benefit period from 90 to 98 days, at 50% of wages, for up to two occasions. A different entitlement period may be prescribed by Ministerial Regulation.
- Disability Benefits: Increases the monthly income replacement benefit for non-work-related disability from a maximum of 50% to a maximum of 70% of wages.
8. Old-Age Benefits
The Draft Bill introduces greater flexibility in the payment and calculation of old-age benefits, including the following:
- Calculation of Benefits: Wages previously used as the basis for calculating old-age contributions will be adjusted to their present value when calculating benefits.
- Pension or Lump-Sum Gratuity: Insured persons with at least 180 months of contributions may choose between a monthly old-age pension and a lump-sum old-age gratuity upon reaching the age of 55 or upon termination of insured status, subject to the prescribed conditions.
- Payment Following Unemployment Benefits: Where an insured person remains entitled to unemployment benefits, payment of old-age benefits will commence only after the unemployment benefit entitlement ends.
- Advance Pension: Eligible pension recipients may apply for an advance payment of up to 60 times their monthly pension, subject to the criteria, procedures and discount prescribed by Ministerial Regulation.
- Partial Withdrawal: An insured person, or a former insured person with at least 60 months of old-age contributions, may withdraw part of their contributions before reaching the age of 55 or before their insured status ends, in the event of a serious disaster affecting their livelihood.
- Use as Loan Collateral: An insured person, or a former insured person with at least 60 months of old-age contributions, may use part of their old-age contributions as collateral for a loan from a financial institution that has entered into an agreement with the SSO.
- Withdrawal and Collateral Limits: The amount available for partial withdrawal or use as loan collateral is limited to 30% of the person’s old-age contributions and may not exceed twice the maximum wage base applicable to that person.
- Repayment and Restoration of Entitlement: Full old-age benefit entitlement may be restored upon repayment of the amount received, together with the Fund’s investment opportunity cost.
- Death Before Receiving Old-Age Benefits: The SSO may deduct the relevant outstanding amount from the benefits payable to a person who dies before receiving old-age benefits. Any remaining balance will be payable to the person’s heirs.
9. Unemployment Benefits
The Draft Bill clarifies the eligibility requirements for unemployment benefits. To qualify, an insured person must:
- Be aged 60 or below;
- Have made contributions for at least six months within the 15 months preceding unemployment; and
- Not be receiving old-age benefits at the time of claiming unemployment benefits.
10. Penalties
The Draft Bill revises certain penalties under the Social Security Act by replacing criminal penalties with regulatory fines under the Act on Imposition of Pinai Regulatory Fines, B.E. 2565 (2022), as follows:
- Survey Forms: Intentionally failing to complete or return a survey form, or providing incomplete information, will be subject to a regulatory fine of up to THB 5,000.
- Employer Reporting Requirements: Employers who fail to submit employee registration forms within 30 days from the date an employee becomes insured, fail to notify the SSO of changes to relevant information by the 15th day of the following month, or fail to submit contribution forms by the statutory deadline will be subject to a regulatory fine of up to THB 20,000, plus an additional daily fine of up to THB 5,000.
- False Information: Criminal penalties will continue to apply to employers who knowingly submit false information concerning insured persons, wages or other required particulars, or who submit false contribution statements. These offences remain punishable by imprisonment for up to six months, a fine of up to THB 20,000, or both.
11. Transitional Provisions
The Draft Bill includes transitional provisions to ensure continuity following its entry into force:
- Home Workers Protection Committee: Existing members will remain in office until the employer and insured-person representatives are appointed in accordance with the amended Section 8(3).
- Continued Insurance under Section 39: Former Section 33 insured persons who have contributed for at least 12 months, and whose insured status ended due to termination of employment, may continue insurance under Section 39 on the basis of the previous eligibility requirements, provided that they notify the SSO within six months from the date their insured status ends.
Current Legislative Status
Following the Cabinet’s approval on 3 November 2026, the Draft Bill will be submitted to the House of Representatives Coordination Committee before proceeding to the House of Representatives for consideration. Cabinet’s approval does not bring the proposed amendments into effect. The existing Social Security Act will remain in force until the Draft Bill completes the legislative process and the amendment is promulgated and enters into force.
The Cabinet also acknowledged the Ministry of Labor’s plan to prepare 18 subordinate legal instruments, comprising one Royal Decree, eight Ministerial Regulations, six regulations and three notifications. These instruments are expected to be prepared within 60 days from the date the Draft Bill enters into force.
