Thailand (TH)
Thailand is one of the world’s largest expat hubs, combining Bangkok’s regional business ecosystem, Chiang Mai’s remote-worker scene, Phuket and Pattaya’s retirement and tourism communities, and strong international schools and hospitals.
Social Security in Thailand
Benefits, contributions, and how the system works for expats.
Thailand social security is mainly employment-based for private-sector employees under the Social Security Office. Foreign employees with lawful employment are commonly registered and contribute alongside employers. The system is useful but not a full expat safety net: benefits are tied to contribution history, assigned hospitals and statutory caps, so most expats combine it with employer benefits or private insurance.
Social Security Office insured-person number
SSO insured person registration
Your employer registers you with the Social Security Office after employment starts. You provide passport, work permit or employment documents, address and bank details. Confirm registration on your payslip and request your SSO details from HR. If you change employer, do not assume the old registration flows perfectly to the new job: check the new employer contribution month, assigned hospital and whether there is any gap in coverage.

Contribution Overview
The standard employee and employer contribution is commonly 5% each, calculated on wages up to the statutory monthly ceiling used by SSO. The government also contributes. Temporary rate changes can occur by policy, so verify current payroll rates on SSO announcements and your payslip in 2026. Because the contribution wage ceiling is low compared with many expat salaries, SSO benefits do not replace a high income. Treat SSO as a statutory baseline, not as full salary protection or premium medical cover.
International Social Security Agreements
Thailand has more limited social-security coordination than EU systems. Do not assume your Thai SSO contributions combine with your home-country pension. Posted workers and employees sent by foreign employers should get specialist advice on double coverage, payroll location and treaty position. If you are paid offshore while physically working in Thailand, the social-security answer can differ from the immigration, tax and labour-law answer.
SSO is valuable but narrow. The assigned-hospital model, wage cap and benefit formulas mean high-earning expats should not rely on it as their only health, disability or retirement planning. Keep SSO records, payslips and work-permit files because benefit claims often depend on contribution proof. At each job change, download or screenshot contribution history, request final payroll documents and confirm whether voluntary continuation is available or useful for your situation. For families, coordinate SSO with private health cover so spouse, children and newborns are not accidentally outside both systems.
