Most expats who take up formal employment in Phuket get their first Thai social security (ประกันสังคม, pragan sangkhom) card in their first week, promptly file it somewhere, and give it very little thought thereafter. Meanwhile, 5% of their salary disappears each month to the Social Security Office (SSO) and they have no real idea what they get in return.
The honest answer is: it depends heavily on whether you engage with it or not. Thai social security provides real healthcare, maternity benefits, sick pay, disability and death coverage — but accessing these benefits requires knowing the system. This guide covers what you actually get, what it costs, and how to make the SSO work for you as an expat employee in Phuket.
Thai Social Security — Key Numbers 2026
- Employee contribution (Section 33): 5% of salary, capped at ฿750/month
- Employer contribution: 5% of salary, capped at ฿750/month
- Government contribution: 2.75% of salary
- Maximum monthly contribution (employee): ฿750 (on salary ฿15,000+)
- Hospital network: Designated hospital — you choose when registering
- Self-employed option: Section 40 — ฿70, ฿100 or ฿300/month voluntary
- Phuket SSO office: Wichit Songkram Road, Phuket Town
- Pension qualifying age: 55+ with 180+ months contributions
Section 33: Employed Worker Coverage
If you're employed by a Thai company on a Non-B visa with a work permit, your employer is legally required to register you with the SSO as a Section 33 insured person. This happens automatically — your employer deducts 5% from your salary each month and submits contributions on your behalf. You should receive a Social Security card within the first few months of employment.
Section 33 covers: illness and injury (including outpatient and inpatient care at your designated hospital), maternity benefits, child allowance, disability benefits, death benefits, and a pension after 180+ months of contributions. As an expat, the most immediately relevant are healthcare, maternity, and the disability/death protection.
Healthcare Under Section 33
This is where most expats get confused. Thai SSO healthcare does not provide free access to Bangkok Hospital or Siriroj Private Hospital — those are private facilities. SSO covers treatment at your designated government hospital or a specific hospital in the SSO network.
In Phuket, SSO network hospitals include Vachira Phuket Hospital (government), Patong Hospital, and some registered private network hospitals. When you register, you choose your designated hospital — and you generally need to use that hospital for non-emergency treatment to be covered.
⚠ Important: SSO ≠ Full Coverage
Most expats in Phuket maintain both SSO coverage through employment and separate private health insurance. SSO provides a safety net for major events (accidents, serious illness) through the government hospital network. Private insurance (Cigna, Pacific Cross, AXA) provides access to Bangkok Hospital, Siriroj, and the full private healthcare system. If your employer provides SSO, that's a good start — but it doesn't replace private international health insurance for most expats' needs.
Contribution Rates & Caps
| Contribution Type | Rate | Monthly Cap | Annual Cap |
|---|---|---|---|
| Employee (Section 33) | 5% of salary | ฿750 | ฿9,000 |
| Employer | 5% of salary | ฿750 | ฿9,000 |
| Government | 2.75% of salary | ฿412.50 | ฿4,950 |
| Section 40 Tier 1 | Flat rate | ฿70 | ฿840 |
| Section 40 Tier 2 | Flat rate | ฿100 | ฿1,200 |
| Section 40 Tier 3 | Flat rate | ฿300 | ฿3,600 |
The cap means that if you earn ฿15,000 or more per month, your monthly SSO deduction is fixed at ฿750 — regardless of whether you earn ฿15,001 or ฿150,000. High earners pay the same nominal amount as someone on the minimum qualifying salary.
Section 40: Voluntary Coverage for Self-Employed
If you're not in formal employment (for example, operating under a DTV digital nomad visa or working through your own Thai company structure), you can voluntarily enrol in Section 40. The three tiers offer different benefit packages at very low cost:
| Section 40 Tier | Monthly | Key Benefits |
|---|---|---|
| Tier 1 | ฿70/month | Work injury/accident: ฿50,000 disability, ฿50,000 death benefit |
| Tier 2 | ฿100/month | Tier 1 + old age pension (฿600/month from age 60) |
| Tier 3 | ฿300/month | Tier 2 + illness benefit (up to 30 days at ฿300/day) |
Section 40 is genuinely useful for freelancers and self-employed expats who want basic coverage for serious accidents and a token old-age benefit. At ฿70–฿300/month, it's not a substitute for health insurance — but the accident and death benefits provide a meaningful safety net.
Benefits You Can Actually Claim
Under Section 33, expats can claim the same benefits as Thai nationals. Practically, the most accessible are:
Medical care: Free or low-cost treatment at your designated SSO hospital. Present your SSO card when registering. Emergency treatment at any hospital is covered regardless of designation (up to a cap).
Sick pay: If hospitalised and unable to work, SSO pays 50% of salary (capped at ฿7,500/month) for up to 90 days per year. Requires doctor's certificate from SSO-registered hospital and employer documentation.
Maternity: ฿15,000 lump sum (one-time per pregnancy) plus sick pay at 50% of salary for 90 days maternity leave. Both mother and father on SSO can claim the ฿15,000 (but can only combine once per child). Requires 5 months of contributions in the 15 months before the birth.
Death benefit: If an insured person dies, SSO pays funeral costs (฿40,000 currently) to the next of kin, plus a survivor's benefit if sufficient contributions were made.
Insider Tip: Hospital Choice Matters
When you first register with SSO or transfer your designated hospital, choose carefully. In Phuket, Bangkok Hospital's SSO-registered outpatient clinics in some areas are in the network — but not the main private facility. Vachira Phuket Hospital (government) has the most comprehensive SSO-covered services in Phuket. For routine care (blood tests, prescriptions, minor ailments), the SSO government hospital system is functional and extremely cheap. The Phuket SSO office is on Wichit Songkram Road — or you can manage your account online at sso.go.th.
Claiming Back Contributions: The Lump Sum Question
A common question from expats leaving Thailand: "Can I get my contributions back?" The short answer is no — Thailand does not refund SSO contributions the way some countries (e.g., Japan) do for departing foreign nationals. Your contributions fund current beneficiaries in a pay-as-you-go structure.
The exception: if you have paid in for 180+ months (15 years) and are aged 55+, you become eligible for the old-age pension — either a monthly payment or a lump sum. Very few expats reach this threshold, but it's worth knowing if you're a long-term resident planning to retire in Thailand.

Get Private Health Insurance for Phuket
SSO provides a safety net but doesn't cover Bangkok Hospital or Siriroj Private. Most expats add a private plan for full Phuket healthcare access.
