The short answer
China taxes people, not just income earned in China — but only if you are a tax resident. For foreigners, residency hinges on a single number: 183 days in a calendar year. Cross it and you are a resident taxpayer in principle; stay under it and China taxes only your China-source income. A second mechanism, the six-year rule, then decides when worldwide income actually enters the Chinese tax net. Here is how both work.
Who is a resident taxpayer
Under China's Individual Income Tax (IIT) Law, you are a resident individual if either:
you have a domicile in China (generally: Chinese household registration / habitual residence with no plan to leave), or
you have no domicile in China but have resided in China for an aggregate of 183 days or more in a tax year (January 1 to December 31).
Everyone else is a non-resident individual, taxed only on income sourced in China.
A critical counting detail: only days on which you are in China for the full 24 hours count toward the 183. The day you arrive and the day you leave — if either involves less than 24 hours in China — do not count (per Announcement 2019 No. 34).
What residents vs non-residents pay on
Resident individuals are in principle subject to IIT on worldwide income — but for foreigners without a domicile, the six-year rule (below) usually defers the foreign-income part.
Non-resident individuals pay IIT only on China-source income, typically via withholding at source, with no annual settlement filing for most employment income.
The six-year rule: when worldwide income actually bites
Being a 183-day resident does not immediately expose your foreign income. A foreigner without a domicile in China is exempt from IIT on income that is both sourced outside China and paid by an overseas entity or individual — until the six-year clock runs out.
The exemption is lost (and worldwide income becomes taxable) only if, in each of six consecutive tax years, the individual:
resided in China for 183 days or more, and
did not have a single absence from China of more than 30 consecutive days in any of those years.
The six-year count started on January 1, 2019, regardless of earlier years. That means 2025 was the first tax year in which anyone could have completed six consecutive qualifying years — the rule is now live, not theoretical.
The clock resets entirely if, in any year, you spend fewer than 183 days in China or take one single trip out of China lasting more than 30 consecutive days. Note: it must be a single continuous absence of 30+ days, not 30 days accumulated across several trips.
Two more conditions for the exemption: you must file a record with the competent tax authority claiming it, and the foreign income must be paid by a non-China payer (foreign income paid or borne by a Chinese entity is taxable in China regardless).
The annual settlement (汇算清缴)
Resident individuals with comprehensive income (wages, salaries, labor remuneration, author's remuneration, royalties) must complete an annual IIT settlement from March 1 to June 30 of the following year, reconciling withholding against actual liability — claiming extra deductions or paying any shortfall. Non-residents generally do not file the annual settlement.
Common mistakes
Counting travel days wrong. Arrival and departure days under 24 hours do not count. People who "feel" they spent half the year in China often land under 183 on the legal count — or over it when they assumed otherwise.
Ignoring the 30-day reset. One 31-day trip home in a year restarts the six-year clock. It is the single most important planning lever for long-term expats.
Forgetting the filing requirement. The six-year exemption requires an affirmative filing with the tax bureau — it is not automatic.
Assuming the old five-year rule still applies. The 2019 IIT reform replaced the old five-year lookback with the six-year rule and the 183-day test.
Mixing up domicile. If you hold Chinese household registration (hukou) or are otherwise domiciled, the six-year shelter does not apply to you at all — you are a resident taxpayer on worldwide income from day one.
Frequently asked questions
I spent 200 days in China in 2026 but left for 40 days straight in March. Am I a resident?
You likely meet the 183-day test and are a resident for 2026 — but the 40-day absence resets your six-year clock, so qualifying foreign-source income paid by overseas payers stays exempt for 2026.
Does rental income from my apartment back home count as foreign-source?
Yes, if the property is outside China and the tenant/payer is outside China. But once the six-year rule is exhausted, it becomes taxable in China — and you may need to claim foreign tax credits for tax paid abroad.
What if my foreign employer pays me through a Chinese entity?
Then the "paid by an overseas entity" condition fails — that income is China-connected and taxable in China regardless of the six-year rule.
Do short business trips out of China break the 30-day rule?
No — only a single continuous absence of more than 30 days resets the clock. Several 2-week trips do not.
Where do I file the six-year exemption record?
With the tax bureau in charge of your registration (usually where your employer withholds, or your local bureau). Your employer's payroll provider or a local tax agent typically handles it.
