China social insurance affects statutory benefit protection, payroll deductions, employer cost and local employment compliance. This guide explains the five insurances, their relationship with the housing provident fund, calculation rules, foreign-employee participation and why a private waiver cannot replace statutory contributions.
What is China social insurance?
China social insurance is the statutory system covering basic pension, basic medical, unemployment, work-injury and maternity insurance. Maternity and employee medical insurance are implemented together while benefit protection continues. The housing provident fund is a separate housing-savings system, commonly administered alongside the five insurances through payroll.
In everyday HR language, companies often talk about “five insurances and one fund.” The “five insurances” are social insurance. The “one fund” is the housing provident fund. The housing fund is not technically social insurance, but it is closely linked to payroll and is often handled together with social insurance in employer cost planning.
Category | What it covers | Who usually contributes? | Employer relevance |
|---|---|---|---|
Pension insurance | Retirement income protection after contribution and retirement conditions are met | Employer and employee | Usually one of the largest social insurance cost items for employers |
Medical insurance | Medical expense support for illness or non-work-related injury | Employer and employee | Often administered with maternity insurance in city-level payroll practice |
Unemployment insurance | Support for eligible employees after involuntary unemployment | Employer and employee in many cities | Rates are usually lower than pension or medical insurance, but still require accurate filing |
Work injury insurance | Protection for occupational injury or occupational disease | Employer only | Rate can depend on industry risk and local rules |
Maternity insurance | Maternity-related medical expenses and maternity allowance where applicable | Employer side in most payroll practice | Often merged administratively with medical insurance in many cities, but remains part of the statutory benefit framework |
Housing provident fund | Long-term housing savings account for eligible employees | Employer and employee | Not social insurance, but usually included in “five insurances and one fund” cost planning |
For employers, social insurance is not optional. It should be built into payroll, onboarding, budgeting, and offboarding from the start of the employment relationship.
The NPC text of the Social Insurance Law, Article 2 identifies the five categories. National Healthcare Security Administration guidance explains the joint implementation of maternity and employee medical insurance, rather than abolishing maternity benefits. See medical insurance in China for the healthcare branch.
Why does social insurance matter for employers?
Social insurance matters because it affects both compliance and employment cost. A salary offer may look simple on paper, but the employer’s total cost is usually higher once employer-side social insurance and housing fund contributions are added.
For foreign employers in China, social insurance affects:
- Monthly payroll cost
- Employee deductions
- Employee net salary
- Employer statutory contribution cost
- Social insurance registration
- City-level filing procedures
- Annual contribution-based adjustments
- Employee benefit entitlement
- Labor-dispute exposure
- Offboarding and account transfer
- Foreign employee compliance
- Payroll documentation and audit readiness
For companies with an existing China entity, China payroll outsourcing can help manage salary calculation, individual income tax, social insurance, housing fund, payslips, and payroll reporting. For companies hiring in China without a local entity, China EOR can help manage employment and payroll through a compliant local structure.
How the framework has developed
The Social Insurance Law took effect in 2011. Later changes include the joint administration of employee medical and maternity insurance, updates to the foreign-employee participation rules in December 2024, and the Supreme People’s Court’s 2025 clarification on contribution-waiver arrangements. For employers, the practical response is to keep onboarding, payroll registration, benefit records and exit procedures aligned with the current rules, rather than carrying old settings forward.
These changes concern different obligations; broader social-security coverage does not make every benefit automatic or replace city-specific contribution and benefit-claim conditions. The law, NHSA implementation guidance, amended foreign-participation rules and court interpretation linked in this guide provide the relevant primary sources.
How are China social insurance contributions calculated?
Social insurance contributions are generally calculated by applying local contribution rates to an employee’s contribution base. The contribution base is usually determined by the employee’s wage income, subject to the local minimum and maximum base.
Because the floor, cap, and rates are locally administered, identical salaries can produce different employer and employee costs in different cities.
For accurate payroll, employers should check the social insurance rates and contribution bases by city instead of relying on a national estimate.
For a city-by-city comparison, see HROne’s 2026 China social insurance contribution rates, including employer and employee percentages, contribution bases, and calculation examples for Beijing, Shanghai, Guangzhou, and Shenzhen.
Payroll item | Basic calculation logic | Who bears the cost? |
|---|---|---|
Employer pension contribution | Local pension contribution base × employer pension rate | Employer |
Employee pension contribution | Local pension contribution base × employee pension rate | Employee, withheld through payroll |
Employer medical contribution | Local medical contribution base × employer medical rate | Employer |
Employee medical contribution | Local medical contribution base × employee medical rate | Employee, withheld through payroll |
Work injury insurance | Contribution base × employer work-injury rate | Employer only |
Unemployment insurance | Contribution base × local unemployment insurance rates | Employer and employee in many cities |
Maternity insurance | Often administered with medical insurance; local rate rules apply | Employer side in most payroll practice |
Housing fund | Housing fund base × employer and employee housing fund rates | Employer and employee |
The safest approach is to calculate social insurance city by city and employee by employee, especially when employees work in different locations or have different salary levels.
Worked Example: Shanghai Employee Earning RMB 15,000
Assume an employee earns RMB 15,000 gross monthly and both the properly determined social-insurance base and housing-fund base are RMB 15,000. A registered contribution base may reflect prior-year wages rather than the current salary; this equality is an explicit example assumption. Select ordinary housing-fund contributions of 7% per side and a Class I work-injury benchmark of 0.2%; the actual assessed work-injury rate can differ. No supplementary housing fund or special employee treatment is included.
| Insurance / fund | Employer rate | Employee rate | Assumed monthly base | Employer monthly amount | Employee monthly amount |
|---|---|---|---|---|---|
| Basic pension | 16% | 8% | RMB 15,000 | RMB 2,400 | RMB 1,200 |
| Medical, including maternity | 9% | 2% | RMB 15,000 | RMB 1,350 | RMB 300 |
| Unemployment | 0.5% | 0.5% | RMB 15,000 | RMB 75 | RMB 75 |
| Work injury | Assumed Class I benchmark: 0.2% | 0% | RMB 15,000 | RMB 30 | RMB 0 |
| Ordinary housing provident fund | Selected example: 7% | Selected example: 7% | RMB 15,000 | RMB 1,050 | RMB 1,050 |
| Total social insurance + ordinary fund | — | — | — | RMB 4,905 | RMB 2,625 |
Employer social insurance alone is RMB 3,855; adding the assumed ordinary housing fund gives RMB 4,905. Salary plus these employer contributions is RMB 19,905, before other benefits or service charges. Employee deductions total RMB 2,625, leaving RMB 12,375 before individual income tax and other adjustments.
Shanghai’s 2026 social-insurance base guidance gives a base range of RMB 7,546–37,731 from July 1, 2026. Its September 2026 employee contribution guide and employer-rate FAQ provide the relevant rate framework. The 2026 medical-insurance notice sets employer 9% and employee 2% from March 1, 2026 to February 28, 2027; Shanghai’s work-injury notice sets industry benchmarks subject to floating assessment.
The 7% housing-fund selection follows the 5%–7% per-side ordinary-fund framework in the management centre’s published guidance. Check the current annual policy notice and the actual registered base and ratio before applying the example; use the actual registered base and approved ratio for payroll, as annual adjustments may change the applicable limits.
For other locations and current local inputs, use social insurance rates and bases by city.
Is minimum wage the same as the social insurance contribution base?
No. China minimum wage is the applicable local wage floor. A social-insurance contribution base is the amount to which contribution rates apply, determined under local wage-income, floor and cap rules. Housing-fund bases follow their own local rules. Do not substitute the minimum wage for either registered contribution base.
What is the difference between employer cost and employee take-home pay?
Employer cost and employee take-home pay are not the same. In China, payroll normally has two separate views: the employee-side view and the employer-side view.
The employee-side view starts with gross salary, deducts employee social insurance, employee housing fund, individual income tax, and any lawful agreed deductions, then arrives at net salary.
The employer-side view starts with gross salary, then adds employer social insurance, employer housing fund, and any employer-only costs.
View | Formula | Why it matters |
|---|---|---|
Employee net pay | Gross salary − employee social insurance − employee housing fund − IIT − other lawful deductions | Shows what the employee receives after statutory deductions and tax withholding |
Employer total cost | Gross salary + employer social insurance + employer housing fund + employer-only costs | Shows the real monthly cost of employing the worker |
Minimum wage compliance | Gross wage must not fall below the applicable local minimum wage standard | Protects the employee wage floor, but does not replace social insurance calculation |
Employers should communicate salary in gross RMB terms and explain deductions clearly. If USD is used for overseas budgeting, it should be treated only as an approximate conversion, not the legal payroll basis.
What does housing fund add to the calculation?
The housing provident fund is a separate payroll-linked contribution system. It is not technically social insurance, but it is often managed together with social insurance because both affect payroll cost and employee deductions.
Under China’s housing fund framework, both the employer and employee make contributions to the employee’s housing fund account. The Regulations on Management of Housing Provident Fund provide that the monthly housing fund contribution is calculated based on the employee’s average monthly salary and the applicable contribution rate.
Housing fund matters because it can materially increase both employer cost and employee deductions. It also varies by city. Some companies underestimate China labor cost because they count only social insurance and forget housing fund. Others use the wrong housing fund base or apply outdated local contribution rules.
For more detail, see HROne’s housing provident fund in China.
Do foreign employees need to participate in China social insurance?
The MOHRSS Interim Measures on Social Insurance for Foreigners Employed in China, amended December 2024 require lawful foreign employees within their scope to participate in the specified insurances. Article 4 requires registration within 30 days of obtaining the relevant employment document; Article 9 addresses treaty treatment. Nationality alone does not establish a waiver.
Bilateral Social Security Agreements
The following agreements are identified as in force in the cited official material. Exemption applies only to persons, insurance branches and periods covered by the actual agreement and accepted certificate. It is not a waiver of all Chinese social insurance or a general exemption for anyone holding that passport.
| Country | Entry into force | Potentially exempt Chinese insurance branches | Required proof |
|---|---|---|---|
| Germany | April 4, 2002 | Basic pension and unemployment | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| South Korea | January 2013 | Basic pension and unemployment | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Denmark | May 14, 2014 | Basic pension | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Canada | January 1, 2017 | Basic pension | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Finland | February 1, 2017 | Basic pension and unemployment | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Switzerland | June 19, 2017 | Employee basic pension, resident basic pension and unemployment, as applicable to the covered person | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Netherlands | September 1, 2017 | Basic pension and unemployment | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Spain | March 20, 2018 | Basic pension and unemployment | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Luxembourg | May 1, 2019 | Basic pension | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Japan | September 1, 2019 | Basic pension | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Serbia | February 1, 2021 | Basic pension and unemployment | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
| Kyrgyzstan | October 14, 2025 | Employee basic pension and resident basic pension, as applicable to the covered person | Certificate of coverage from the competent home-country institution; local filing and approval of the covered period. |
For the pre-existing eleven-country branch summary, see the local HRSS published agreement table and the MOHRSS treaty texts and implementation notices linked by country. The MOHRSS October 2025 notice confirms Kyrgyzstan’s entry into force; older eleven-country lists do not include that later event. The Korean authority lists January 2013 as the entry-into-force month.
A certificate must identify the insured person, applicable legislation/branches and period. Submit it to the competent Chinese authority and retain the accepted filing; continue non-exempt contributions. The official national service-platform explanation describes the certificate process, but its older country-status summary must be read with later implementation notices. Follow the detailed handling guidance for bilateral social security agreements.
Can social insurance be waived or converted into cash salary?
No. A private promise to waive statutory contributions does not make non-payment lawful. Article 19 of the Supreme People’s Court Interpretation (II) on Labor Disputes, Fa Shi [2025] No. 12, effective September 1, 2025, provides that agreements or employee undertakings not to pay social insurance are invalid. Where the employer fails to pay as required and the employee terminates under Labor Contract Law Article 38(1)(3), the court supports the statutory economic-compensation claim.
The same article addresses return of a previously paid social-insurance subsidy after the employer makes the required back-payment. Keep statutory contributions, cash subsidies and employee compensation distinct; assess the facts and applicable collection and labor-dispute procedures before promising a settlement.
How should employers calculate China labor cost?
Employers should begin with the role, city, salary, contribution base, and employment structure. A useful budget should show at least four layers: gross salary, employer social insurance, employer housing fund, and other employer-side costs.
Planning step | What to check | Why it matters |
|---|---|---|
Confirm the work city | Where the employee will actually work and where benefits should be registered | Contribution rules, bases, caps, and housing fund practice vary by city |
Check local minimum wage | Monthly and hourly wage floors in RMB | Prevents below-minimum pay, especially for junior, part-time, probationary, or dispatched roles |
Determine gross salary | Base salary, allowances, bonus, commission, overtime, and other wage items | Salary structure affects payroll, IIT, contributions, and disputes |
Apply contribution bases | Local social insurance and housing fund floors and caps | Prevents underpayment and overpayment |
Separate employer and employee amounts | Employer-side cost versus employee-side deductions | Clarifies budget, offer communication, and employee net-pay expectations |
Update annually | Contribution base adjustment windows, wage updates, and city policy changes | China payroll assumptions can become outdated quickly |
For a broader payroll cost view, HROne’s guide on payroll and tax compliance in China can be used together with city-level social insurance checks.
Use the employee’s city, correctly determined bases, actual assessed rates and employment package to calculate employer cost.
How should employees understand their deductions?
Employees should understand that social insurance deductions are not the same as tax. Employee social insurance and housing fund contributions are statutory payroll deductions that support benefit entitlements or individual accounts. Individual income tax is a separate withholding item.
A clear payslip should help employees see:
- Gross salary for the month
- Employee pension contribution
- Employee medical contribution
- Employee unemployment contribution, where applicable
- Employee housing fund contribution, where applicable
- Individual income tax withholding
- Net salary paid
- Employer-side contributions, where the company provides this breakdown
Clear communication matters because employees may compare gross salary, minimum wage, net pay, and employer cost incorrectly. Employers should explain offer packages in RMB and show whether a salary is gross or net.
Common employer mistakes
Foreign employers often run into social insurance issues because they underestimate city-level rules or rely on overseas payroll assumptions.
Common mistakes include:
- Confusing the local wage floor with social-insurance or housing-fund contribution bases.
- Assuming one national social insurance rate. Rates, bases, caps, and housing fund practice vary by city.
- Confusing minimum wage with contribution base. Social insurance contribution bases often depend on wage income and local average-wage-based floors and caps.
- Leaving foreign employees out of social insurance without review. Treaty exemptions may exist, but they require eligibility and documentation.
- Trying to convert social insurance into cash salary. Social insurance obligations cannot be waived by private agreement.
- Ignoring housing fund. Housing fund is often a significant employer and employee cost item even though it is not technically social insurance.
- Failing to update payroll systems after annual base adjustments. Old contribution bases can create underpayment or overpayment risk.
- Not aligning contract salary, payroll, IIT, and contribution reports. Mismatches can trigger audit questions and employee disputes.
China social insurance checklist for employers
Compliance area | Employer action |
|---|---|
Minimum wage | Confirm the local RMB wage floor for the employee’s work location and employment type. |
Contribution base | Check local social insurance and housing fund base floors and caps before payroll setup. |
Employee registration | Register new employees for social insurance and housing fund within local required timelines. |
Foreign employees | Confirm work authorization, social insurance participation, and treaty exemption documentation if relevant. |
Payroll records | Maintain payslips, contribution reports, IIT records, employee files, and benefit payment proof. |
Annual updates | Review contribution base adjustments, minimum wage updates, and city policy changes every year. |
Employee communication | Explain gross salary, net salary, employee deductions, and employer contributions clearly. |
Audit readiness | Ensure contract salary, payroll, IIT filings, social insurance records, and housing fund contributions align. |
How HROne supports China social insurance compliance
For a company with its own China employing entity, outsourced social insurance administration supports the agreed payroll and contribution process. Where broader HR administration is needed, China PEO support operates alongside the company’s own employer responsibilities. For an eligible arrangement without a client-owned employing entity, China EOR services provide the agreed local employment and payroll structure.
Confirm the employing entity, employee location, registration, monthly approval calendar, contribution evidence, correction process and offboarding responsibilities in the actual service scope.

FAQ: China Social Insurance
What is China social insurance?
China social insurance is the statutory employee benefit system covering pension, medical, unemployment, work injury, and maternity insurance. It is established under China’s Social Insurance Law and applies to standard employment relationships.
What are the five insurances in China?
The five insurances are basic pension insurance, basic medical insurance, unemployment insurance, work injury insurance, and maternity insurance. They are often discussed together with the housing provident fund as “five insurances and one fund.”
Is China social insurance mandatory?
Yes. Social insurance is generally a statutory obligation for employers and employees under standard employment relationships in China. Employers should register employees and make contributions according to local rules.
Is housing fund part of social insurance?
No. Housing fund is not technically social insurance, but it is usually managed together with social insurance in payroll because it affects employer cost and employee deductions.
Is minimum wage the same as the social insurance contribution base?
No. Minimum wage is the local legal wage floor. The social insurance contribution base is the amount used to calculate contributions and is subject to local floors and caps. It is often linked to wage income and local average wage rules, not simply the minimum wage.
Do foreign employees need social insurance in China?
Foreign employees legally employed in China are generally required to participate in China’s employee social insurance system unless an applicable treaty exemption or local treatment applies. Employers should verify treaty eligibility and filing requirements rather than assuming exemption automatically.
Can employees waive social insurance contributions?
No. Employers and employees cannot validly agree to waive statutory social insurance contributions or convert them into cash salary. Social insurance is a legal obligation.
How are social insurance contributions calculated?
Social insurance contributions are usually calculated by multiplying the employee’s local contribution base by the applicable employer and employee rates. Contribution bases, caps, floors, and rates vary by city.
Why does social insurance affect employer cost?
Employer social insurance contributions are paid in addition to gross salary. This means the employer’s total monthly employment cost is higher than the employee’s gross salary.
How can payroll outsourcing help with social insurance in China?
Payroll outsourcing can help employers calculate social insurance and housing fund contributions, apply local contribution bases, manage monthly filings, prepare payslips, maintain payroll records, and reduce city-level compliance errors.
Does China have a social security system?
Yes. China has a statutory social insurance system covering pension, medical, unemployment, work-injury and maternity protection. Employer and employee contributions follow the applicable insurance and local rules. The housing provident fund is separate. Benefit entitlement depends on the relevant contribution history, insured status and claim conditions.
