The Social Security Office clarifies issues concerning the accumulated balance data of the 'old-age fund' on the SSO Plus app that does not match previous information.
On 5 Feb 2026 GMT+7, the Social Security Office explained that some insured persons found discrepancies between their accumulated old-age fund balances on the SSO Plus application and previous records.
The investigation revealed several causes: insured persons residing in areas where contribution rates were temporarily reduced, such as during flood crises with reduced contributions in certain areas; during the COVID-19 pandemic; or during economic downturns. Other causes include insured persons working for multiple employers simultaneously and those holding coverage under both Section 33 and Section 39 within the same month. The previous SSO Plus system did not account for these factors in its calculations.
Additionally, the Social Security Office has standardized the data presentation format across all channels, including the e-Self Service system, applications, government portals, and others, to ensure accuracy and consistency.
The old-age contribution data displayed on the SSO Plus app is calculated from a combined 6% contribution—3% from the insured person and 3% from the employer. For example, an insured person with a monthly salary of 15,000 baht would contribute a total of 900 baht monthly for old-age fund contributions from both parties.
The updated SSO Plus app accounts for periods when contribution rates were reduced proportionally. For instance, from May to July 2022 GMT+7, contributions were set at 1%, with 0.05% allocated to the old-age fund. An insured person earning 15,000 baht would thus accumulate 7.50 baht monthly for the old-age fund, totaling 15 baht from both parties.
Regarding old-age benefit eligibility, insured persons must end their coverage and be at least 55 years old. Those who contributed less than 180 months receive a lump-sum old-age benefit plus returns, which exceed the amount shown on the SSO Plus app. Those with contributions of 180 months or more receive a lifelong old-age pension plus returns. The Social Security Office announces annual return rates for lump-sum old-age benefits, which vary each year.
The Social Security Office apologizes for any inconvenience caused and has improved its service system to provide insured persons with accurate, transparent information and full benefits as mandated by law.
