Corporate Secretarial · Scenario S.20
Register Your First Employee with Thailand's Social Security Office
A Thai company must register with the Social Security Office within 30 days of hiring its first employee — establishing both the employer's SSO account and the employee's enrolment simultaneously. From that point, monthly contributions are due by the 15th of every following month. An employer that misses the registration deadline faces penalties and continues to accrue liability for unremitted contributions. UnionSPACE handles the employer and employee registration in a single engagement — completed in 7–14 working days.
Two Registrations Required at Once — Employer and Employee
A company hiring its first employee has a 30-day window to register with the Social Security Office under the Social Security Act. This registration has two components that must be completed together: registering the company as a new SSO employer and enrolling the first employee under that employer account.
From the month of registration, both the employer and the employee contribute 5% of the employee's monthly salary — capped at THB 750 per party per month — remitted together to the SSO by the 15th of the following month. These monthly contribution remittances begin immediately and must be made every month regardless of whether any other compliance activity is underway.
An unregistered employee has no access to the social security benefits they are entitled to — medical treatment at SSO hospitals, maternity, disability, and unemployment benefits — for the unregistered period. This is an obligation that protects the employee, not just a box the employer is required to tick. UnionSPACE completes the full registration within 7–14 working days from receipt of required documents.

Three Obligations That Begin the Month Your First Employee Starts
All three require the SSO registration to be in place first
Monthly Contribution Remittances
From the month of registration, the employer must remit both the employer contribution (5% of salary, capped at THB 750) and the employee's withheld contribution (also 5%, capped at THB 750) to the SSO by the 15th of the following month — every month without exception. These remittances are required even if the employee is on leave or the company has no other activity that month. Late payment attracts surcharges of 2% per month.
Employee Benefits Access
An employee enrolled with the SSO is entitled to medical treatment at SSO-registered hospitals, maternity and child benefits, disability and death benefits, and unemployment benefits — funded by the combined monthly contributions. An employee who is not correctly registered cannot access any of these benefits for the unregistered period. Registration is the employee's gateway to their entitlements, not merely an administrative requirement for the employer.
Additional Employee Enrolments
Once the employer SSO account is established, each subsequent employee must be enrolled within 30 days of their start date. This is not a separate employer registration each time — the employer account is already in place. Subsequent enrolments are simpler and faster than the first registration. UnionSPACE can handle subsequent employee enrolments as part of ongoing HR compliance support.
From employer obligations review to confirmed enrolment — what happens at each stage
How We Handle First Employee SSO Registration in Thailand
Employer Obligations Review & Document Collection
We confirm the company's SSO registration status — first-time employer or existing employer adding a first employee to a dormant account — and identify the correct registration forms for the SSO area office responsible for the company's registered address. We collect the company affidavit and registration documents, and the employee's name, Thai ID or passport number, and salary details.
The SSO area office that handles the registration is determined by the company's registered address — not by where the employee works. Where the employee works at a different location, we confirm whether a separate registration at a different area office is required. Using the wrong office causes the filing to be redirected and adds processing time.
SSO Application Preparation
We prepare both the employer registration form (establishing the company's SSO account and employer number) and the employee enrolment form (registering the first employee under that account). Both forms must be submitted together on first registration. We confirm the monthly contribution amount based on the employee's stated salary and advise on the first remittance deadline.
The contribution rate is 5% of monthly salary per party, calculated on a salary base capped at THB 15,000. The maximum contribution is THB 750 per party per month regardless of actual salary. We confirm the applicable rate and the first payment deadline so the payroll team can plan accordingly before the forms are submitted.
SSO Submission & Enrolment Confirmation
We submit both forms to the SSO area office, manage all officer liaison, and deliver confirmation of both the employer account and the employee enrolment once the registration is processed. We advise on the first contribution remittance deadline and the SSO hospital selection process so the employee can access medical benefits without delay.
SSO processing times vary by area office — typically 4–9 working days once the forms are submitted. During peak periods such as the beginning of the year, processing can extend. We track progress and advise if any additional documentation is requested by the officer.
- Preparation: 3–5 working days from receipt of required documents.
- SSO processing: 4–9 working days (area office dependent).
- Total end-to-end: 7–14 working days.
- Statutory registration deadline: 30 days from first employee's start date.
Frequently Asked Questions — SSO Registration for a First Employee in Thailand
Answers to the questions we are asked most often
Within 30 days of the first employee's start date. The registration covers both the employer (creating the company's SSO account) and the first employee (enrolling them as a contributor). Missing this deadline results in penalties and continued liability for unremitted contributions from the date employment began. Engage us as soon as the start date is confirmed.
Both the employer and the employee each contribute 5% of the employee's monthly salary, calculated on a salary base capped at THB 15,000. The maximum contribution is THB 750 per party per month, regardless of actual salary. The employer withholds the employee's share from salary and remits both portions to the SSO by the 15th of the following month. Late remittances attract a 2% per month surcharge.
Yes. Foreign employees who work in Thailand on a valid work permit are generally subject to the same SSO contribution obligations as Thai employees. The registration process is the same. UnionSPACE handles both domestic and foreign employee SSO registrations. Foreign employees who are also being registered with the Revenue Department (Scenario S.34) can have both registrations coordinated simultaneously.
A registered employee under Section 33 of the Social Security Act is entitled to: medical treatment at SSO-registered hospitals; maternity and child benefits; disability and death benefits; and unemployment benefits. These entitlements are funded by the combined monthly contributions and are not available to employees for any period during which they were not registered. Prompt registration protects the employee's access to their full entitlements from day one.
Yes — they are entirely separate. SSO registration covers social security contribution obligations and employee benefits eligibility. Revenue Department registration covers the employee's Tax Identification Number and withholding tax setup. Both are required for a new employee. UnionSPACE handles each as a distinct service and can coordinate both simultaneously for a new hire.
Once the employer SSO account is in place, each subsequent new employee must be enrolled within 30 days of their start date. The employer does not need to re-register — only the new employee enrolment form is required. These subsequent enrolments are simpler and faster than the initial combined employer and employee registration. UnionSPACE handles ongoing employee enrolments as part of continuing HR compliance support.
