Individual income tax in China for foreign employees
Individual income-tax explainer
Start with four facts: your tax year, whether you are domiciled in China, how many days you are in China, and where the work that produces the income is performed. Then add the employer/payment route and any treaty question.
China's individual income tax system has specific rules for resident and non-resident individuals, including people without domicile in China. A general guide can explain the framework, but it cannot determine your personal liability without the facts.
01
1. Start with the tax year and the scope of the question
China's IIT tax year runs from 1 January to 31 December.
Before asking “What tax rate do foreigners pay?”, write down:
- arrival and departure dates;
- days physically present in China;
- whether you have a domicile in China under the tax-law concept;
- employer or employers;
- where work is physically performed;
- which entity pays or bears the compensation;
- China-source and overseas-source income;
- other comprehensive income;
- any tax treaty that may be relevant.
The Chinese legal text controls. Official English versions are useful for orientation but should not be treated as a substitute where wording matters.
A salary calculator cannot answer all of these questions.

2. Understand resident and non-resident concepts
Under China's IIT Law, an individual who is domiciled in China, or a non-domiciled individual who has been in China for 183 days or more in a tax year, is a resident individual for IIT purposes.
A non-domiciled individual who is in China for less than 183 days in a tax year is generally treated as a non-resident individual under the IIT Law.
That is only the first layer.
China also has special rules for individuals without domicile, including the well-known consecutive-year framework for overseas-source income. The implementation rules and 2019 residence-period announcement address when overseas-sourced income paid by overseas entities can remain outside Chinese IIT for qualifying non-domiciled individuals and how a single absence exceeding 30 days can affect the consecutive-year count.
Do not reduce this to “183 days means worldwide tax.” The correct answer depends on domicile, the six-year framework, income source, payer and other rules.
If a treaty is involved, tax-residence and employment-income articles may add another layer.

3. Separate employment income, withholding and final liability
For ordinary salary paid through a Chinese employer, the employer normally acts as a withholding agent and withholds/prepays IIT according to the applicable rules.
Keep:
- payslips;
- gross salary records;
- tax withheld;
- bonus records;
- equity or incentive records;
- overseas-paid compensation records;
- reimbursement and allowance evidence.
Payroll withholding is important evidence, but it is not a guarantee that every tax issue has been resolved.
Questions can arise when you have:
- two employers;
- overseas-paid salary;
- personal-services income;
- a bonus or equity event;
- days worked outside China;
- employer corrections;
- income not captured in payroll.
If the compensation relates to work performed partly inside and partly outside China, individuals without domicile can face source-allocation rules that require a more precise analysis than a monthly tax estimate.

4. Treat allowances, deductions and treaties as separate verification branches
Do not assume that a benefit called “housing allowance” or “school allowance” automatically has a particular tax treatment.
For any allowance or reimbursement, identify:
- legal basis for the treatment;
- your resident/non-resident and domicile status;
- effective period of the relevant policy;
- documentation required;
- whether the employer is treating it consistently in payroll.
China has extended certain IIT preferential policies for allowances and subsidies for foreign individuals, but the exact treatment and eligibility should be checked against the current tax notice rather than copied from an old relocation package.
Deductions are another branch. Resident comprehensive-income taxpayers may have access to statutory deductions when conditions are met, but the correct deduction depends on current law and personal facts.
For treaty claims, identify the treaty, your claimed treaty residence and the article being relied on. Do not use the phrase “183-day treaty exemption” without checking all treaty conditions.

5. Understand annual reconciliation and recordkeeping
China's current Administrative Measures for IIT Annual Reconciliation for Comprehensive Income took effect in February 2025.
The measures provide that taxpayers who need to complete annual reconciliation generally do so from 1 March to 30 June of the following year. The rules also describe who may not need to file, who must file, filing channels and the role of employers or authorised agents.
A non-domiciled taxpayer who will leave China before the annual reconciliation period begins may, under the current measures, be able to complete reconciliation before departure.
Before reconciliation, review:
- comprehensive income;
- tax prepaid;
- deductions;
- bank account details;
- personal data;
- employer records.
The measures require taxpayers and employers handling reconciliation on their behalf to retain relevant supporting information for the prescribed period.
Do not assume that because the employer withheld tax every month, no year-end action is possible or required.

6. Know when to move from self-service to professional advice
Self-service is usually enough to understand payroll and a straightforward annual reconciliation.
A more specific review can be justified when you have:
- multiple employers or payers;
- significant overseas income;
- workdays across countries;
- a treaty-residence question;
- equity or incentive compensation;
- an employer payroll error;
- an audit or tax notice;
- departure with unresolved filings;
- business or freelance income alongside employment.
Start with the State Taxation Administration and the Individual Income Tax APP/official electronic channels. If the official material does not resolve the fact pattern, take a written list of the facts to a qualified tax adviser.
A useful adviser question is precise: “How should this overseas-paid compensation for work partly performed in China be reported for this tax year?” It is better than asking for a generic “expat tax package.”
