Social Security & Universal Coverage for Foreigners

Social security 5% deduction / cap THB 750/month · free treatment at network public + private hospitals

AI Quick Answer

Foreigners working legally in Thailand (work permit + Non-B) pay Social Security Section 33 at 5% of salary, capped at THB 750/month (max base THB 15,000). Entitled to free treatment at the chosen network hospital (one per year) — covers OPD/IPD/surgery/ER/dental/maternity (after 12 contributions) + sick leave + childcare allowance + unemployment 50% × 90 days. After leaving employment, rights persist 6 months. Without a work permit, Universal Coverage (Bat Tong) is not available — private insurance is required.

Frequently asked questions

Does it cover everything?

Standard Thai health cover pays for outpatient visits, inpatient admission, surgery and emergency treatment inside the insurer's network. Cosmetic procedures, fertility treatment including IVF, most alternative medicine and experimental therapies sit outside the benefit schedule. Complex or specialist cases are commonly referred onward to a university hospital such as Siriraj or Chulalongkorn under the same referral rules.

Does my family get coverage?

Thai social security covers the insured employee only; a spouse and children are not automatically included. Families usually add a private policy for dependants, or register non-employed relatives under the voluntary Section 40 scheme, which offers several low-cost benefit packages with a modest monthly contribution but far narrower medical coverage than an employer-based Section 33 registration.

Can I combine with private insurance?

Combining the two is common and usually the most economical structure. Social security is used first at your registered hospital, and a private top-up policy then covers what the state scheme does not: a private room, treatment outside the registered hospital, a second opinion, additional specialist consultations and higher surgical limits. Tell both providers so the claims are coordinated correctly.

Maternity coverage?

12 contributions → THB 15,000/child normal delivery + 13,000 ANC + 5-day paternity leave + childcare allowance THB 800/month × 6 years.

Unemployment payout?

50% of salary cap THB 7,500/month × 90 days (lay-off) or 30% × 90 days (resign) — requires 6 contributions in 15 months.
