The question a foreign hire asks in the first week is almost never about the rate. It is: if I pay into this for four years and then go home, do I get anything back?
The answer is more favourable than most expatriates expect, and it is one of the few places where the rules for foreign nationals are more generous than those for Chinese citizens. It also runs against what a lot of HR teams believe, which is that foreign staff can opt in or out.
Who has to be enrolled
Enrolment is mandatory, not optional. Article 97 of the Social Insurance Law says foreigners employed in China participate by reference to that law, and MOHRSS Order No. 16 turns that reference into an obligation.
Article 2 of the Order defines who counts: a non-Chinese national lawfully working in China, holding a work permit or foreign correspondent card together with a residence permit, or holding a permanent residence ID. Two employment routes are covered by Article 3:
- Directly hired by an entity registered in China — the employer and the employee both contribute.
- Seconded by a foreign employer to a branch or representative office in China — the Chinese host entity and the employee both contribute.
So a secondee whose salary is still paid in Tokyo is not outside the system. The Chinese host entity enrols them and pays the employer share.
Two limits worth noting. The employee must be below the statutory retirement age — someone who has already reached it is not enrolled. And the obligation is triggered by lawful employment, so it starts with the work permit, not with the first payday.
Article 4 sets a hard deadline: registration within 30 days of the employment certificate being issued. Late registration does not extinguish the liability; it accrues from the date it should have happened.
The five contributions
Article 3 lists all five: basic pension, basic medical, work injury, unemployment, and maternity. There is no reduced package for foreign nationals — the common assumption that only work injury insurance applies is wrong.
Contribution rates are set locally, so they differ between cities, but the structure is consistent:
| Scheme | Employer | Employee | Notes |
|---|---|---|---|
| Pension | ~16% | 8% | Employee share goes entirely to the personal account |
| Medical | ~9-10% | 2% | Employee share partly to a personal account in some cities |
| Work injury | ~0.2-1.9% | 0 | Rate varies by industry risk class |
| Unemployment | ~0.5-0.8% | ~0.2-0.5% | Varies by city |
| Maternity | ~1% | 0 | Merged into medical in some cities |
The base is capped. Each city sets a floor and a ceiling, usually tied to a multiple of the local average wage — commonly 60% to 300%. A foreign executive earning far above the ceiling contributes on the ceiling, not on actual salary. That matters for planning: the marginal cost of a large package flattens once the cap is reached.
The contribution base in practice
The rates are the visible part; the base is where the money actually is. Each city publishes a floor and a ceiling annually, tied to the local average wage — typically 60% and 300%. Contributions are computed on the actual monthly wage, clamped into that range.
Take a city where the average monthly wage is 12,000 yuan, giving a range from 7,200 to 36,000. Two employees, one on 25,000 and one on 80,000:
| Monthly salary | Contribution base | Employee pension 8% | Employer pension 16% |
|---|---|---|---|
| 25,000 | 25,000 | 2,000 | 4,000 |
| 80,000 | 36,000 | 2,880 | 5,760 |
The second employee earns more than three times the first and contributes 44% more. For a company budgeting an expatriate package, that flattening is material: above the ceiling, a salary increase costs nothing in social insurance, and a package structured with allowances rather than base pay does not reduce the contribution either — the base is total wages, not base salary.
The eleven treaty countries
China has signed bilateral social security agreements with a number of countries, and eleven are in force:
Germany, Korea, Denmark, Canada, Finland, Switzerland, the Netherlands, Spain, Luxembourg, Japan and Serbia.
France and Kyrgyzstan have signed but their agreements are not yet in effect. A French national working in Shanghai today is therefore fully liable, and should not be treated as exempt on the strength of the signature alone.
The purpose of these agreements is to stop double contribution — a secondee posted to China for three years should not pay into both systems for the same period. What each agreement covers differs: some exempt pension only, others pension and unemployment, and the exemption usually applies for a defined period, commonly five years, sometimes extendable.
The exemption is not automatic. Article 9 of MOHRSS Order No. 16 defers to the agreement, and every agreement requires a certificate of coverage issued by the social security authority of the home country. Without that document in hand, the Chinese entity must enrol and contribute. Being a German national is not itself an exemption — the certificate is. HR teams that discover this after a payroll run usually discover it as arrears plus late fees.
What happens when they leave
This is where the rules are better for foreign nationals than for Chinese citizens, and it is the part worth explaining carefully to the employee.
Article 5 of MOHRSS Order No. 16 gives two options for someone who leaves China before reaching pension age:
- Keep the account. The personal account is preserved, and if the person returns to work in China, contribution years continue to accumulate from where they stopped.
- Close it and take the balance. On a written application to terminate the social insurance relationship, the balance of the personal account is paid over in a lump sum.
Compare that with the general rule for Chinese nationals, under which early withdrawal is permitted only in narrow circumstances — leaving the country and losing Chinese nationality being the main one. A foreign employee does not have to give up nationality, and does not have to wait. A written application is enough.
Be precise about what comes back. Only the personal account balance is refunded — in pension terms, the 8% the employee contributed plus accumulated interest. The employer's 16% went into the pooled fund and is not refundable. An expatriate who has been told "you get it all back" will be disappointed at the counter; one who understands they recover roughly their own contributions plus interest will not be.
Article 6 adds that on death the balance of the personal account passes to the estate. Article 7 requires anyone receiving a monthly benefit from outside China to verify survival status annually.
Interaction with individual income tax
Contributions within the prescribed scope are deductible before individual income tax is computed, on the same basis as for Chinese employees. The employee's own share reduces taxable wages; the employer's share is not treated as taxable income to the employee.
There is a related sequencing point that catches people out. For a foreign national who has chosen the duty-free allowance route rather than the special additional deductions — the election described in the expatriate IIT note — social insurance contributions still come off first. The two are not alternatives to each other; the deduction for contributions applies regardless of which allowance election was made.
Records and transfers
Individual contribution records are visible through the local social insurance app or the online portal, and a new foreign hire should be shown how to open them — the account is the only independent proof of what has been paid.
Two mechanics matter. Moving between cities inside China, pension and medical accounts transfer: contribution years carry across, and the pooled portion moves under the rules agreed between the two localities. And on departure, the lump-sum payment requires an application and the closure of the relationship, so an employee who has kept their own record of contribution months will find the process considerably shorter than one relying on a former employer's files.
Secondment: who carries the obligation
Where a foreign parent seconds staff to its Chinese subsidiary, the obligation sits with the Chinese host entity, even though the employment contract is with the overseas parent. Article 3 of MOHRSS Order No. 16 says so directly.
That is a commercial issue as much as a compliance one. A secondment agreement that is silent on social insurance leaves the Chinese entity bearing roughly a quarter of payroll in employer contributions with no contractual right to recharge it to the parent. The fix is a clause, not a tax position — but it is routinely omitted, and the cost lands on the entity that has the weaker negotiating position.
Where employers get it wrong
- Treating enrolment as voluntary. It is not. "The employee preferred the cash" is not a defence.
- Enrolling secondees only in work injury. Article 3 lists five schemes for secondees as well.
- Assuming treaty nationality equals exemption. The certificate of coverage is the operative document, and it must be obtained before enrolment, not after.
- Missing the 30-day window. Registration is tied to the employment certificate date, which HR often receives later than the start date.
- Contributing on full salary above the ceiling. Over-contribution is harder to unwind than under-contribution.
- Promising a full refund on departure. Only the personal account balance returns.

Status note. The list of treaty countries changes as agreements are ratified, and the count has moved from six in 2017 to eleven today. Verify the current position for the specific nationality before relying on an exemption. Contribution rates and base ceilings are set city by city and are revised annually.
