Employee Termination — SSO Update
When an employee leaves a Thai company, the Social Security Office must be notified within 15 days of the departure. An employer that fails to file continues to be assessed for social security contributions for an employee no longer on the payroll. The departing employee's benefit eligibility records remain uncorrected, creating complications at their next employer. UnionSPACE prepares the termination notification, submits to the SSO, and delivers confirmation of the updated records — completed in 3–7 working days.
Why the 15-Day Filing Window Matters for Both Employer and Employee
The Social Security Act requires an employer to notify the Social Security Office of an employee's departure within 15 days of the last day of employment. This is not a formality — it has direct financial consequences for both the company and the departing employee.
For the employer: until the notification is filed and accepted, the company continues to be assessed for social security contributions for a person no longer on the payroll. Monthly contribution amounts accumulate. Reclaiming overpaid contributions requires a correction filing that adds further administrative cost and delay.
For the employee: their Social Security benefit eligibility — including unemployment benefits — is tied to their recorded employment status. An employee whose departure is not reported remains recorded as active at the previous employer, which can prevent them from claiming benefits when they register with a new employer. Properly filing the termination notification is an obligation that protects both parties.

Three Reasons Not to Delay the SSO Termination Notification
Each applies from the day after the employee's last day of employment
Continued Contribution Assessments
Until the SSO termination notification is filed and accepted, the company continues to be assessed for social security contributions for the departed employee. Each month of delay adds to the assessed contribution liability for a person who is no longer working. Reclaiming overpaid contributions requires a correction filing — an additional cost and delay that is entirely avoidable by filing promptly after departure.
Employee Benefit Complications
A departed employee whose SSO record shows them as still active at the previous employer may not be able to claim unemployment benefits or access their benefits entitlement at a new employer until the record is corrected. This creates a practical problem for the employee and can damage the company's relationship with the departing person — particularly where the departure is on good terms or involves a senior employee.
SSO Audit Exposure
The Social Security Office conducts employer record audits. A company whose SSO records show active employees who have in fact departed — particularly where contributions were not remitted for those employees during the gap — creates an inconsistency that attracts SSO scrutiny. Filing termination notifications promptly keeps the company's records accurate and reduces audit exposure.
From termination date confirmation to SSO records update — what happens at each stage
How We Handle an Employee Termination SSO Update in Thailand
Termination Review & Document Collection
We confirm the employee's name, Thai national ID or passport number (as registered with the SSO), the last day of employment, and the company's SSO employer registration number. We verify the employee's SSO record to confirm they are currently registered as active at the company — and identify whether the 15-day filing deadline has been met or whether a late filing explanation may be required.
Where multiple employees are departing within the same period, we identify all of them at this stage so the notifications can be batched into a single filing — more efficient and cost-effective than filing separately for each departure.
SSO Termination Form Preparation
We prepare the SSO termination notification form — stating the employee's name, SSO registration number, last day of employment, and reason for departure — in the format required by the Social Security Office area office responsible for the company's registered address. The completed form is reviewed before submission.
The SSO notification updates the Social Security Office records only. It does not automatically update the Revenue Department's records for withholding tax purposes. The departing employee should be removed from the next monthly Por Ngor Dor 1 withholding tax return — this is handled as part of the monthly accounting service where UnionSPACE also manages payroll and tax compliance.
SSO Submission & Records Confirmation
We submit the completed termination notification to the relevant SSO area office, manage any officer liaison, and confirm that the employee's record has been updated to reflect the departure. Confirmation of the update is delivered digitally.
Once the SSO records are updated, the company's monthly contribution assessment for the following period will no longer include the departed employee. If contributions were remitted for the employee after the departure date — due to delayed filing — the company may apply for a correction to reclaim the overpayment. We advise on this at the point of confirmation where it applies.
- Preparation: 1–3 working days from receipt of required information.
- SSO processing: 2–4 working days (area office dependent).
- Total end-to-end: 3–7 working days.
- Statutory filing deadline: 15 days from last day of employment.
Frequently Asked Questions — Employee Termination SSO Updates in Thailand
Answers to the questions we are asked most often
The Social Security Act requires notification within 15 days of the last day of employment. Filing after this deadline may result in continued contribution assessments for the period of the delay and may attract SSO queries. We recommend engaging us as soon as the departure date is confirmed — the 3–7 working day process fits comfortably within the 15-day window for most departures.
The company continues to be assessed for social security contributions for the departed employee. Monthly contribution amounts accumulate. The employee's benefit eligibility records remain uncorrected, preventing them from claiming unemployment benefits or registering with a new employer's SSO contribution scheme. The SSO may also flag the discrepancy during a routine employer audit.
No. The SSO and the Revenue Department maintain separate records. The SSO notification updates only the Social Security Office records. The monthly withholding tax return (Por Ngor Dor 1) must separately reflect the employee's departure by removing them from the payroll from the following month. This is managed as part of the monthly accounting and payroll compliance service.
Yes. Where multiple employees depart within the same period, their termination notifications can be submitted together in a single filing — more efficient than submitting separately for each employee. Contact us with details of all departing employees and we will confirm the most efficient approach and provide an adjusted quote where applicable.
Where contributions were remitted after the departure date — due to delayed filing or a payroll processing lag — the employer may apply to the SSO for a correction and reclaim the overpaid amount. The reclaim process requires a separate application and supporting documentation. We advise on this at the point of confirmation of the termination notification where an overpayment is identified.
No — this service covers the termination notification for a departing employee. Registering a new employee with the SSO is a separate process handled under the employee on-boarding compliance service. Contact us if you need assistance with new employee SSO registration and we will confirm the applicable process and fee.
