China’s social security system is well-structured and mandatory for all employees working in the country, covering five types of insurance and a mandatory housing fund. Contribution rates, bases and administrative procedures vary by city, so employers operating across multiple locations need to manage compliance at the local level rather than relying on a single national framework.
This guide outlines the different insurance schemes, contribution rates and potential compliance risks for businesses.
- Chinese social security covers pension, medical insurance, unemployment insurance, work-related injury insurance, maternity insurance and mandatory housing fund.
- Contribution rates vary based on the city of employment. The employer and employee each contribute a percentage of the employee’s income towards different schemes.
- The social security contribution base is determined by the employee’s average income in the previous year.
- Despite the cost burden, social security contributions offer benefits such as tax deductions, risk resistance, talent recruitment advantages and support during maternity leave.
What does China’s social security system cover?
China’s social security system was established to provide financial protection for employees across key life and work events. It is administered nationally under the Social Insurance Law but managed locally, meaning rates, bases and administrative processes differ by city.
| Insurance type | What it covers | Who contributes |
|---|---|---|
| Pension | Retirement income based on contribution years and account balance | Employer and employee |
| Medical insurance | Treatment at designated public hospitals, with a portion into a personal medical account | Employer and employee |
| Unemployment insurance | Temporary income support if employment ends involuntarily | Employer and employee |
| Work-related injury insurance | Medical costs and compensation for workplace accidents or occupational illness | Employer only |
| Maternity insurance | Medical costs and income replacement related to childbirth | Employer only (integrated into medical in some cities) |
| Housing provident fund | Mandatory savings mechanism to support housing purchases or rental | Employer and employee |
In some cities, including Shanghai, maternity insurance has been integrated into the medical insurance pool, reducing the number of separately administered schemes to four plus the housing fund.
Social security contribution rates in China
The contribution rate for each scheme and fund is based on the location (city) of the employment. The table below provides an overview of the contribution rates in Shanghai:
| Benefit | Employer contribution rate | Employee contribution rate |
|---|---|---|
| Pension | 16% | 8% |
| Medical insurance | 10% | 2% |
| Unemployment insurance | 0.5% | 0.5% |
| Maternity insurance | 0.5% | 0% |
| Work-related injury insurance | 0.2% – 1.9% | 0% |
| Housing fund | 5% – 7% | 5% – 7% |
How the contribution base is calculated
The social security contribution base is calculated by the employee’s average income in the previous year using the following method:
Social security contribution base = Total income of previous year / 12
New employees in their first year use their starting salary as the base. The base is subject to a ceiling, typically set at 300% of the local average salary, and a floor linked to the local minimum wage or a fixed percentage of the average local salary.
Both the floor and ceiling are published annually by local authorities, usually taking effect in July. Employers need to update contribution bases each year in line with the official notices for each city where staff are based. For a full breakdown of how contribution bases interact with individual income tax withholding, see our guide on monthly payroll processing in China.
Risks of non-compliance with social security payments
Some companies attempt to cut costs by avoiding social insurance payments, choosing a lower base instead of using the previous year’s average salary. However, such practices are strongly discouraged for several reasons:
- If an employee reports underpayment to authorities, the Social Security Bureau generally sides with the employee. This could leave the company liable for underpayment, penalties and interest.
- The Social Security Bureau will recalculate the underpayment for both employer and employee portions and apply a late interest fine of 0.05% per day on overdue amounts.
- Companies undergoing due diligence for financing, IPOs or M&A deals need to avoid any irregularities that could impact their reputation or value.
- Non-compliance creates structural weaknesses in a company’s compliance management framework that can compound over time.
What are the benefits of social security for foreign investors in China?
Despite representing a significant payroll cost, social security contributions offer practical advantages that go beyond basic compliance. For most businesses operating in China, the benefits across tax, risk coverage, talent and workforce management outweigh the administrative burden.
Corporate income tax deductions
Employer’s mandatory social security payments for employees can be considered reasonable salary expenses and are deducted from corporate income tax.
Risk coverage
Work-injury insurance is crucial in high-risk industries like manufacturing. For minor injuries, employees can seek medical treatment with partial coverage from medical insurance. For serious injuries, the government reimburses medical expenses, but this relies on timely reporting by the employer. Failure to contribute can leave employers liable for these costs.
Talent attraction and retention
Social security compliance is a baseline expectation for employees in major cities. Companies that offer additional benefits, such as a supplementary housing fund, can use this as a meaningful differentiator in competitive talent markets.
Maternity leave support
During maternity leave in Shanghai, employers do not need to pay salaries; the government provides maternity allowances directly to female employees. This policy varies by city; in Beijing, companies pay salaries during maternity leave, with the government reimbursing later.
Social security exemptions under bilateral agreements
According to regulations, everyone working in China, including foreigners (though local practice might vary) contributes to social insurance. However, China so far has signed Totalisation Agreements with 12 countries to prevent double contributions, of which 11 are currently in force. Eligible nationals from these countries may be exempt from specific social security contributions while working in China, provided they remain covered under the corresponding system in their home country.
The 11 countries with agreements currently in force are Germany, South Korea, Denmark, Canada, Finland, Switzerland, the Netherlands, Spain, Luxembourg, Japan and Serbia. An agreement with France has been signed but is not yet in effect.
The scope of each agreement differs. Most cover pension and unemployment insurance only, while others may extend to additional categories. Employers need to apply through the relevant local social insurance bureau and submit supporting documentation, including a certificate of coverage from the home country authority. Foreign employees departing from China can also claim back certain contributions when closing their social insurance account.

Conclusion
The Chinese social security system provides protection to both employers and employees, but it can be a significant financial commitment, especially compared to other countries. Despite this, its extensive coverage offers substantial benefits.
These mandatory contribution obligations cannot be exempted by mutual consensus between employers and employees, and failing to make timely or sufficient payments exposes employers to compliance risk. It is recommended that businesses consult local experts to ensure accurate contributions, compliance with regulations and risk mitigation.
