When a company in China employs a foreign national under a local employment contract, it triggers two mandatory obligations: social insurance registration and individual income tax (IIT) withholding. These are separate from the work and residence permit processes but equally critical for legal compliance. Failure to register for social insurance or correctly withhold IIT can result in back payments, late-payment surcharges, and penalties for the employer, as well as potential disruption to the employee's visa status. Finerise Consultants provides clear guidance on exactly what is required, including the impact of China's social security agreements with other countries and the latest tax rules for foreigners.

➦ Part 1: Social Insurance for Foreign Employees

✔ Who Must Be Insured

• Under the Social Insurance Law of the PRC, any foreigner who has signed a local employment contract with a company in China is, in principle, required to participate in the full social insurance scheme, regardless of nationality.
• A foreigner seconded by an overseas parent company and not holding a direct China employment contract may fall outside the mandatory scope, but this must be assessed case by case.
• Representative offices that cannot directly hire local staff typically employ foreign nationals through third-party HR agencies; the employing agency is responsible for social insurance registration.

✔ Which Social Insurances Apply

China's social insurance system comprises five main schemes:

• Pension (Endowment) Insurance: Employer contribution ~16%, individual ~8% (rates vary slightly by city).
• Medical Insurance: Employer ~8%, individual ~2%, plus a small fixed amount for the maternity component (which has been merged into medical insurance in most cities).
• Work-Related Injury Insurance: Employer only; rate varies by industry (typically 0.2%–1.9%).
• Unemployment Insurance: Employer ~0.5%, individual ~0.5% (rate may vary).
• Maternity Insurance: Now combined with medical insurance in most jurisdictions; employer contribution only.

Actual rates and policies should always be verified with the local social insurance bureau, as Guangzhou, Foshan, Shenzhen, and other cities may have slightly different implementation rules.

✔ Social Security Agreements (Totalisation Agreements)

China has signed bilateral social security agreements with a number of countries to avoid double coverage and to allow the aggregation of insurance periods for pension eligibility. As of 2026, these agreements exist with, among others: Germany, South Korea, Japan, Canada, the Netherlands, Finland, Luxembourg, Denmark, Spain, and Switzerland. Each agreement specifies which categories of workers are exempt from contributing to China's pension and/or unemployment insurance for a defined period (typically 5 years, renewable). To benefit from an exemption, the foreign employee must present a Certificate of Coverage issued by the home country's competent institution.

✔ Contribution Base and Ceilings

Contributions are calculated on the employee's actual monthly salary, subject to local floors and ceilings (usually 60%–300% of the city's average monthly wage). The employer must register the employee with the social insurance bureau within 30 days of the employment start date and make monthly contributions through the electronic system.

➦ Part 2: Individual Income Tax (IIT) for Foreign Employees

✔ Tax Residency: Resident vs. Non-Resident

• Non-resident taxpayer: A foreigner who stays in China for fewer than 183 days in a calendar year is generally a non-resident and taxed only on income sourced from within China. No annual reconciliation is required if income is solely salary from the Chinese employer with tax correctly withheld monthly.
• Resident taxpayer: A foreigner who stays in China for 183 days or more in a calendar year is treated as a resident and is subject to IIT on worldwide income. They must file an annual tax return (March 1 to June 30 of the following year) if their annual income exceeds the threshold or if the employer has not fully withheld the tax.

✔ Taxable Income and Rates

Employment income (salaries, bonuses, allowances, etc.) is taxed under the comprehensive income category at progressive rates from 3% to 45%. The standard deduction is RMB 5,000 per month (RMB 60,000 per year).

✔ Special Deductions and the Foreigner Tax-Free Allowance Option

Under the 2018 IIT reform, foreign residents can choose either:

• Standard special additional deductions: the same deductions available to Chinese residents (child education, continuing education, housing loan interest, housing rent, elderly care, and, for children under 3, infant care). Or
• Tax-free allowances (the "old" foreigner benefit): a foreigner may claim reasonable tax-free reimbursement for housing rent, meal expenses, laundry, relocation expenses, language training fees, and children's education fees, if the employer's policy and proper invoices support such claims. This alternative is available until 31 December 2027 (extended by MOF/STA Announcement No. 29 of 2023). The two methods cannot be combined in the same year.

Employers must decide which method to apply for each foreign employee and implement it consistently during the year. Our payroll and tax team can model the most tax-efficient strategy for each individual.

✔ Withholding and Filing Obligations

The employer must withhold IIT from the employee's monthly salary and remit it to the tax authority by the 15th of the following month. For resident taxpayers, if the total annual income exceeds the threshold, an annual reconciliation must be completed by the following June 30. Non-residents do not need to file an annual reconciliation if only one employer withheld tax correctly.

➦ Why Choose Finerise for Payroll, Social Insurance, and Tax Filing?

We run a compliant monthly payroll for your foreign and local staff, calculate the correct IIT withholding, register and file social insurance contributions, and handle all related reporting — all coordinated with your work permit and residence permit status.

✔ Social Security Agreement Expertise

We determine whether your foreign employee can legally be exempted from China's pension and unemployment insurance under a bilateral agreement and assist in obtaining the necessary Certificates of Coverage from the home country.

✔ Tax Optimisation (within the law)

We advise on the choice between standard special deductions and tax-free allowances for resident foreigners, ensuring the employer does not miss the 2027 deadline and that claims are supported by proper documentation.
