China’s social-insurance system covers basic pension, basic medical, unemployment, work-injury and maternity insurance. Employers must enroll covered employees and make accurate contributions under the rules of the relevant location. A contract promising higher net pay or a cash allowance generally does not replace a statutory contribution duty.
The national framework is implemented through local contribution bases, rates and procedures. Foreign employees are covered under specific national measures, subject to any applicable bilateral social-security agreement and its certificate requirements. Employers should verify the employee, employing entity, work location, payroll base and current local rules instead of applying one national percentage.
Direct answer
Register the employing entity, enroll each covered employee promptly and calculate contributions using the current local base and rates. Reconcile payroll, employment records and agency filings every month. Keep proof of enrollment, declared wages, employer and employee contributions, payments and corrections.
Do not combine social insurance with the housing provident fund. They are separate systems with different authorities, accounts, contribution rules and remedies. A complete benefits review should cover both, but each requires its own calculation and evidence file.
The five social-insurance schemes
The Social Insurance Law establishes basic pension, basic medical, work-injury, unemployment and maternity insurance. The allocation of contributions differs by scheme. For example, work-injury insurance is funded by employer contributions under the national law, while other schemes can include employer and employee portions under applicable rules.
Benefits, eligibility, pooling and administration also differ. Avoid describing social insurance as one account or assuming that payment into one scheme cures a gap in another.
Employer registration and employee enrollment
The national law requires an employer to complete social-insurance registration and to apply for employee registration within the statutory framework. Current integrated government systems may exchange establishment data between authorities, but the employer remains responsible for checking successful setup and accurate employee records.
At onboarding, confirm the legal employer, actual start date, work location, identity information, employment category and prior account. Align the employment contract, payroll entity and contribution entity. Cross-entity payroll or secondment arrangements need specific analysis rather than informal allocation within a group.
Contribution base and local rates
Contribution calculations depend on the locally applicable base, floors, caps, rates and annual adjustment cycle. The employee’s previous-year average monthly wage is often relevant, but new hires, transfers, bonuses, allowances and exceptional payments require current local treatment.
Use a city-specific calculation sheet that records:
- scheme and employer/employee rate;
- effective period;
- wage items included or excluded;
- minimum and maximum base;
- employee-specific base;
- rounding and filing method; and
- source notice and retrieval date.
Do not publish or contract around a national “total rate.” Local rules change and may distinguish employer categories or work-injury risk classes.
Payroll withholding and proof
The employer declares and pays contributions and withholds the employee portion where applicable. Payslips should show deductions clearly. Reconcile payroll deductions to authority records and bank payments; a deduction without remittance creates both employee-relations and compliance risk.
Employees have rights to query and verify their contribution and benefit records. Preserve monthly declarations, employee lists, base calculations, payment receipts, corrections and communications with the authority.
Foreign employees
The Social Insurance Law states that foreigners employed in China participate by reference to the law. The Measures for Foreigners Employed in China, revised in December 2024, cover legally employed non-Chinese nationals holding qualifying work, residence or permanent-residence documentation and address employees of China entities and certain overseas employers’ China establishments.
Do not assume all foreign employees are exempt or that local non-enforcement is a legal waiver. Confirm enrollment in the work location and coordinate the employee’s work authorization and identity records.
Bilateral social-security agreements
An agreement between China and the employee’s home state may prevent double contribution for specified schemes and categories. Coverage is not automatic merely because an agreement exists. Check whether it is in force, which schemes and assignments it covers, the maximum period and whether a certificate of coverage or local filing is required.
Keep the certificate, translation, filing receipt and expiry date. Reassess when the assignment, employer, location or term changes. An exemption for one scheme does not necessarily exempt every social-insurance contribution or the housing fund.
Transfers between locations
When an employee moves, identify whether the employment relationship changes, which pooling area becomes responsible and how pension and medical records transfer. Preserve the prior account details, contribution history, transfer application and confirmation.
Do not open duplicate accounts casually or stop contributions before the receiving location is ready. Benefits during the transition, especially medical access, should be planned with current local guidance.
Work injury and operational reporting
Social-insurance compliance is not only payroll. A workplace injury can trigger immediate reporting, evidence preservation, work-injury recognition and benefit procedures. Failure to contribute may expose the employer to costs that would otherwise be borne by the fund, depending on the circumstances and governing rules.
Coordinate HR, safety, payroll and legal teams. Preserve the incident report, medical records, employment evidence, contribution status and authority filings.
Underpayment and correction
An employer that fails to pay contributions fully and on time may be ordered to pay or make up the amount and can face late charges and further sanctions under the Social Insurance Law. Collection authorities have statutory enforcement tools. The employee may also raise contribution issues through available administrative and dispute channels.
Before correcting historic contributions, map affected employees, periods, wage bases, employee portions, tax/payroll records, limitation or local acceptance issues and benefit consequences. Do not alter wage records or request a waiver that contradicts actual employment.
Transactions, restructuring and exit
Benefits diligence should compare the employee roster, contracts, payroll, tax filings, social-insurance accounts and payments by location. Identify contractors treated as employees, cross-entity arrangements, missing months, understated bases, foreign-worker treatment and pending claims.
For a transfer, merger, closure or mass change, plan ongoing coverage, account transfer, final payroll, employee communications and responsibility for arrears. Corporate restructuring does not automatically eliminate historic contribution liabilities.
Compliance checklist
- Confirm the legal employer and each work location.
