China Income Tax for Foreigners: Contracts, Probation and Payroll, by the Book

Quick answer: the four rules that govern your contract and your payslip

The contract. China's labor contract law requires a written contract within one month of your first working day, prescribes nine must-have clauses, and punishes the missing-written-contract case with double monthly wages. Three situations force an open-ended contract on the employer — including when you have already renewed a fixed-term contract twice.

The probation. Probation is capped by law (1–6 months), can only be imposed once per employer, has a wage floor (80% + local minimum wage), and comes with special protection against being fired during it.

The tax. Where your salary is taxed — and on what slice — rides on one number: 183 days of residence in a tax year. Residents get the standard deduction and a progressive annual calculation with a year-end reconciliation; non-residents pay monthly on China-source wages only.

The insurance. Legal employment plugs you into the five-insurance social system, with contributions from both sides. If your country has a bilateral social security agreement with China, part of that burden can be waived for the agreement's period — the list of countries and mechanics is below, differences noted honestly.

Labor contract must-have clauses: what Chinese law writes for you

Foreign employees sometimes treat the Chinese contract as a formality — the offer letter is in English, HR "will translate later", the stamped copy never arrives. The labor contract law (劳动合同法) says otherwise: establishing an employment relationship requires a written labor contract, concluded within one month of the day you start work. Miss that window and the law's penalty structure kicks in (below). The contract's minimum content is enumerated in Article 17:

• The employer's name, domicile and its legal representative (or main person in charge);
• The employee's name, address and ID / valid identity document number;
• The labor contract term (fixed term, open-ended, or task-based);
• The job description and the work location;
• Working hours, rest days and leave;
• Labor remuneration (the pay clause);
• Social insurance — it is a mandatory clause by law, not a perk;
• Labor protection, working conditions and protection against occupational hazards;
• Any other items required by laws and regulations.

Beyond the mandatory nine, the law lets the parties add optional clauses — probation, training and service periods, confidentiality, supplementary insurance and benefits. If any mandatory clause is unclear (pay standards, working conditions), the dispute-resolution ladder runs: renegotiate → apply the collective contract → equal pay for equal work / national standards.

The open-ended contract trigger: when renewal becomes permanent

An open-ended contract (无固定期限劳动合同) is one with no fixed termination date. Either side can propose one by agreement, but the law makes it mandatory — when the employee proposes or agrees to sign, the employer must conclude an open-ended contract — in three situations:

1. The employee has worked for the employer continuously for ten full years;
2. When the employer first introduces the labor-contract system, or re-contracts during restructuring of a state-owned enterprise, and the employee has worked there ten continuous years and has less than ten years to statutory retirement age;
3. The employee has concluded two consecutive fixed-term contracts with the employer, and has none of the dismissal-for-cause or redundancy-adjacent conditions — then the next renewal is open-ended unless the employee asks for a fixed term.

The third one is the trap employers (and recruiters) dance around: renewed a fixed-term contract once? The next renewal, if you agree to continue, is legally open-ended by default. A contract clause saying "renewals are always fixed-term" cannot override the statute.

Probation red lines: the legal caps matrix (期限上限 × 工资下限)

Probation (试用期) is not a free-design clause. The labor contract law fixes the maximum by contract length:

Three more statutory rules complete the matrix:

• Once only: the same employer may agree a probation period with the same worker only once — re-probation after renewal, transfer or "internal promotion" is unlawful;
• Probation-only contracts fail: if a contract stipulates only a probation period, the probation does not exist — that period counts as the contract term itself. Probation is part of the contract term, never an unpaid trial run;
• Protected exit: during probation the employer may not dismiss without cause — the lawful grounds narrow to a statutory shortlist, and any dismissal must state its reasons. "It's not working out" is not a ground.

The probation wage floor: 80% and the minimum wage

The probation salary has a double statutory floor: it must be at least 80% of the wage agreed in the contract or of the unit's same-position lowest wage — and never below the local minimum wage where the employer sits. An offer that "pays 60% during probation" violates the statute, however normal it looks in your home country.

China income tax for foreigners: the 183-day rule, deductions and the annual settlement

China taxes individuals by residence, and residence is a day count. In each tax year (calendar year), the thresholds are 90 days and 183 days, and the official announcement on non-domicile individuals draws the ladder:

Two mechanical notes from the same announcement: a day counts toward work days even for holidays and training taken inside China during a China work period (and a same-day in-out stop counts as half a day in the defined cases); and senior executives of Chinese resident enterprises follow special sourcing rules — bonuses and equity income are allocated by the work-day ratio, not by where the paycheck lands.

The standard deduction: CNY 5,000 a month (60,000 a year)

Resident individuals get the basic deduction — CNY 5,000 per month, 60,000 per year — before rates apply. Non-resident individuals also deduct it when their monthly China-source wages are computed. Beyond the standard deduction, resident employees claim:

• Special additional deductions (专项附加扣除): children's education, continuing education, medical expenses for serious illness, housing loan interest or housing rent, care for the elderly, and infant care — the same menu Chinese residents use, available to foreign residents;
• Special deductions (专项扣除): your social insurance and housing fund contributions;
• Other deductions permitted by law: enterprise annuities, occupational annuities, qualifying commercial health insurance, deferred commercial pension insurance and similar items.

One transition boundary worth knowing: expatriates used to enjoy eight tax-free allowances (housing allowance, language training fees, children's education fees and similar, reimbursed in kind). The official rules let foreign residents choose between the old eight-allowance treatment and the special additional deductions — but never both at once, and the choice-based transition window closed from 2022 per the announcement's own text. If your payroll still deducts "expat allowances" while claiming special additional deductions, that combination no longer exists.

What's the individual income tax rate for foreigners in China?

The same progressive comprehensive-income schedule Chinese employees use — nothing "foreigner-special". Resident individuals apply the annual rate table to comprehensive income after deductions; non-residents apply a monthly-converted table to monthly China-source wages; employers withhold monthly on the official withholding tables and the year-end settlement trues the total up. We deliberately don't reproduce bracket numbers here: the tables are published as attachments to the law and the official withholding measures, and payroll software applies them automatically — copying third-party bracket charts is how last-year's numbers get quoted as this year's law. Ask your payroll provider for the exact bracket printout or use the tax authority's official channels.

The annual reconciliation (年度汇算): March–June, refund or pay

Monthly withholding is an estimate. Resident individuals with comprehensive income — including no-domicile residents — settle the real annual bill after year end: total the four comprehensive-income categories, subtract the deductions, apply the annual table, and compare against what was withheld. The official term is annual reconciliation of comprehensive income (汇算清缴), run through the tax authority's official channels (the individual income tax app or the local tax service hall); the withholding rules state the principle plainly — over-withheld tax is refunded, shortfalls paid. If you leave China mid-year, plan the settlement before departure: it is much easier to claim a refund while you still have a bank account and a phone number.

Social insurance for foreigners in China: the five insurances, the card and the exemption agreements

Under the Interim Measures for Social Insurance of Foreigners Employed in China (a ministry rule, revised by decision effective December 2024), a foreigner employed legally in China — work permit plus residence permit — participates in China's social insurance on the same footing as Chinese employees: the five insurances (basic pension, basic medical, work-related injury, unemployment, maternity), with the employer and the employee both paying contributions and the employer registering you within 30 days of your employment document. Even staff dispatched from abroad and employed by a Chinese-incorporated office are covered. Two honesty notes we write deliberately:

• No national contribution-percentage table here. Contribution rates are set per jurisdiction and move over time — this page does not copy third-party rate tables. Your employer's HR and the local social insurance office hold the current numbers for your city;
• Enrollment is the employer's legal duty, not a negotiable benefit. Cash-in-lieu-of-insurance arrangements leave you outside the system you are legally required to be in — and outside the medical/pension protections you are paying for.

Your social security card for foreigners in China: what it is and how to get it

The social security card (社会保障卡) is the physical carrier of your enrollment: it identifies you to the medical insurance system and to the social insurance offices. It follows enrollment — your employer registers you, and you then apply for the card with the local human resources and social security department (passport and enrollment record are the usual documents; most cities also issue an electronic social security card through official channels). There is no separate "foreigner card" and no legitimate way to get one without proper enrollment — anyone selling a card without registration is selling you a future claim problem. Start at your local social insurance office or the national social insurance public service platform.

Social security agreements: the 12-country exemption list, honestly labeled

China has signed bilateral social security agreements to stop double payment for people who work in both countries. The official notice on implementing the agreements (2025) states the count: 13 signed, 11 in force at its issue date — Germany, South Korea, Denmark, Finland, Canada, Switzerland, the Netherlands, Spain, Luxembourg, Japan and Serbia — with France and Kyrgyzstan signed but not yet in force at that date. Kyrgyzstan's agreement then entered into force on October 14, 2025 per its implementation notice, bringing the in-force list to 12 countries; France remains signed-but-pending. Because this list moves, verify yours on the official topic page of the ministry before you plan around it.

How exemption works: if your country has an in-force agreement and your situation matches its covered categories (seconded employees are the classic case; each agreement defines its own covered persons, benefit types and duration), your employer obtains an official certificate of coverage (参保证明) from the Chinese authorities, and you present it in the partner country to be exempted from that country's covered contributions for the agreed period — while keeping up your home-side coverage. The scope genuinely differs: agreements cover different insurance branches per country, so the exemption you get in Germany is not the one you get in Japan. If your country isn't on the list, there is currently no exemption route: contributions are due in both systems as each requires.

The housing fund: mandatory for employees, revised effective September 2026

The housing provident fund (住房公积金) sits beside the five insurances: units — a list that explicitly includes foreign-invested enterprises — and their employees on the job both contribute, and everything in the account belongs to the employee. The regulation was revised in 2026 (State Council Decree No. 844, effective September 20, 2026) — a revision worth knowing about if you read older guides: the amendment keeps the floor at 5% of the employee's prior-year average monthly wage for each side, adds the national maximum rate cap, lets city committees set the actual rate with provincial approval, and adds a new article pushing digitized records, nationwide mutual recognition of contribution records, and smoother transfers and cross-city loans. Older blog numbers for "housing fund rates" predate this revision — the specifics are set city by city, so treat the 5% floor as the law and your city's notice as the rate.
