Tax for Non-Resident Individuals Providing Services in China: Temporary Work and Your Tax Burden

Meet Anna: A Three-Month Assignment, A Big Tax Question

Anna is a software engineer from Lyon. In March 2025, her French employer asks her to spend three months on a client project in Shanghai. She will receive her usual French salary, paid in EUR into her French bank account. Her HR department has sent her a confusing PDF: ‘China Income Tax for Non-Residents – Temporary Assignment.’ Anna wonders: Will she owe tax in China? The answer, depending on a few simple rules, could be ‘no.’ But understanding why requires unpacking what China calls a ‘non-resident individual,’ how it taxes service income from within China, and how tax treaties override domestic law in her favor.

If you are in a similar situation – or you manage employees who travel to China – this guide breaks down the exact rules and arithmetic.

Who Is a Non-Resident Individual Under Chinese Tax Law?

China’s Individual Income Tax Law distinguishes between two types of taxpayers:

• Resident individuals: those who have a domicile in China, or who have no domicile but have stayed in China for 183 days or more in a single tax year.
• Non-resident individuals: those who have no domicile and have not stayed in China for 183 days or more in a single tax year.

A tax year equals the calendar year from January 1 to December 31.

Note: ‘Domicile’ doesn’t mean having an apartment in Beijing. In Chinese tax law, domicile refers to habitual residence – the country where a person lives due to family, economic, and personal interests. Most foreign professionals in China on short assignments don’t have a Chinese domicile. So the key test is the 183-day stay rule.

Stay counting is mechanical: each day you are physically in China counts, including the day you arrive and the day you depart. So if Anna lands at Shanghai Pudong airport on May 1 and departs on July 31, she will be counted as present for 92 days – not 90, because both arrival and departure days are counted as full days.

Since Anna is present for fewer than 183 days and has no domicile, she is a non-resident individual for China tax purposes. That’s good news: only her China-source income would be taxable in China. Her worldwide salary? Not taxable.

Why Your Work Location Matters: The ‘China Source’ Rule

Non-residents are subject to Chinese income tax only on income that has a source in China. Salary earned as an employee falls under China-source income when the employee’s services are performed in China.

Example: Anna is working on-site in Shanghai from May to July. The compensation paid for those three months is income from personal services performed in China. Under China’s domestic law, that portion is China-source income, even though paid by a French company.

But here’s the catch – China’s domestic law provides a temporary exemption for certain short-term visitors, and tax treaties add another layer.

The 90-Day vs. 183-Day Rule: How Tax Treaties Change Your Result

Under China’s domestic rules (implementing regulations), a non-resident with total stay not exceeding 90 days in a calendar year gets an exemption on the portion of China-source salary that is:

• paid by an overseas employer, and
• not borne by that employer’s permanent establishment in China.

This 90-day exemption applies even if there is no tax treaty.

However, most of China’s double-taxation treaties follow the OECD model and provide a more generous 183-day threshold, subject to the same conditions (salary paid by a foreign employer and not borne by a China permanent establishment).

Because tax treaties prevail over domestic law, a non-resident with a valid treaty can remain exempt even if their stay exceeds 90 days but stays under 183 days.

Note: not all treaties are identical – a few older ones may have different wording or a 90-day threshold. It’s essential to check the specific treaty between China and the taxpayer’s residence country.

For Anna, France and China have a tax treaty that includes the standard 183-day article. So even if her stay is 92 days (over 90), she may still be exempt, provided:

• She is a French tax resident under the treaty (yes, she lives in Lyon).
• She stays in China for 183 days or less.
• Her salary is paid by a French employer (it is).
• The salary is not borne by a permanent establishment of the employer in China (we’ll see if that’s true).

If all these conditions are met, China cannot tax her salary. The right to tax remains solely with France.

A Step-by-Step Example: French Engineer in Shanghai for Three Months

Let’s plug in numbers.

Anna arrives in Shanghai on May 1 and departs on July 31, 2025. That’s 92 days.

If she were not exempt, how would tax be calculated?

For non-resident individuals, salary income uses the monthly consolidated income tax rate table. There is a basic deduction of RMB 5,000 per month, and no special additional deductions.

Suppose her French salary specifically attributable to her China work period is RMB 40,000 per month. Monthly taxable income = 40,000 – 5,000 = 35,000 yuan. Apply the monthly rate table:

• 35,000 yuan falls in the 25% bracket with a quick deduction of 2,660 yuan.

Tax per month = 35,000 × 25% – 2,660 = 6,090 yuan. For three months, that is 18,270 yuan.

However, under the France-China tax treaty, Anna stays only 92 days (≤183), her salary is paid by a French employer, and the employer has no permanent establishment in China bearing the salary. So she is exempt from Chinese individual income tax. If someone had simply looked at domestic law and ignored the treaty, Anna could have paid 18,270 yuan unnecessarily.

What About the Employer? Permanent Establishment Concerns

Anna’s exemption depends not just on her days but on whether her salary is ‘borne by a permanent establishment (PE)’ of her French employer in China.

What is a PE? Under Chinese tax law and treaties, a PE includes a fixed place of business (office, branch, workshop), a building site if it lasts over 6 months, and a service PE if employees provide services in China for a certain period – often 183 days within any 12-month period. If Anna’s employer has a classic PE in China, like a subsidiary or branch that pays her from its own account, the exemption fails. To preserve tax-free treatment, the foreign employer must pay Anna from abroad and the Chinese entity must not charge or reimburse the expense as a deduction attributable to the PE.

In Anna’s case, her French employer might have a wholly-owned subsidiary in Shanghai, but as long as the subsidiary is not acting as the legal employer or bearing the cost of Anna’s salary, she should still satisfy the ‘not borne by a PE’ condition. However, tax authorities will look at the substance, not just paperwork. If the French company invoices its Chinese client for fees that include Anna’s salary, the payer might argue that the salary is borne by the PE created through the service contract. That can get complicated. If the individual is on a consultancy or independent contractor status, rules differ – but here we focus on employees.

The broader question: when a foreign company sends an employee to a Chinese client, does that activity create a PE for the company? Under the China-France treaty, a service PE exists if the individual(s) are present in China for the same or connected project for more than 183 days in any 12-month period. Anna’s three-month stay is far below that, so her employer does not create a PE under the treaty. Therefore the salary is not attributable to a Chinese PE, and the treaty condition is satisfied.

Practical Compliance Tips for Temporary Assignees

Even if your tax liability is zero, you are not immune from paperwork. Here’s what Anna should do:

1. Confirm your treaty eligibility. Provide your Chinese employer or the client with a Certificate of Tax Residence from the French tax authorities.
2. Track your days meticulously. Keep entry/exit stamps and flight itineraries. You don’t want to accidentally exceed the 183-day threshold – that would make you a Chinese tax resident and subject your worldwide income to Chinese tax (though tax treaties mitigate double taxation).
3. Understand who withholds. Under China’s current system, if your salary is paid by a Chinese entity or a foreign entity with a Chinese PE, that entity must withhold individual income tax. If your salary is entirely paid abroad and no PE exists, there is no withholding agent in China. But that doesn’t mean you can skip reporting. The Chinese tax administration expects you to file a return if you have taxable income that has not been withheld. However, if your income is exempt under the treaty, tax law still expects you to claim the exemption – ideally by filing a treaty benefit application or an Individual Income Tax return. In practice, many short-term visitors with no China-source salary (because exempt) do not file, but the safest route is to file a non-resident return or provide the treaty claim to the tax bureau.
4. Protect against double taxation. France taxes Anna as a tax resident on her worldwide income, but she may receive a foreign tax credit for any Chinese tax paid. Since she pays zero in China, she just pays French tax normally.

For more complex cases, especially with stays over 183 days, longer projects, stock compensation, or home-office days, seek advice from a cross-border tax consultant.

Other Income from Services: Independent Contractors

Our discussion so far has centered on employment income. If you are an independent consultant providing services in China, different rules apply – you may be subject to withholding tax on service fees (often 20%–40% on gross income, approximated), and your presence may also trigger a PE for your own foreign firm. Chinese tax authorities also classify residents and non-residents similarly for service income, but the exemption rules for personal service income differ. Always verify with a professional before structuring short-term engagements.

Key Takeaways

• A non-resident individual is someone with no domicile in China and less than 183 days of presence in a calendar year.
• Non-residents are taxed only on China-source income.
• Salary for services performed in China is China-source.
• Domestic law exempts non-residents staying 90 days or less if paid by a foreign employer and not borne by a PE; many tax treaties extend this to 183 days.
• Meet the conditions? You can avoid Chinese tax entirely on a short assignment.
• If not exempt, non-resident wages are subject to monthly brackets, with a 5,000 RMB basic deduction.
• Stay compliant even when tax is zero: document your days, keep a tax residency certificate, and review your employer’s PE risk.

Anna’s story ends well: she completed her project, paid no Chinese income tax, and now can spend her salary on a weekend in Hangzhou. But the numbers only worked because she checked the rules before boarding the plane.

That is the real lesson for temporary work in China: know your days, understand your treaty, and don’t let a misleading PDF be the last word.
