🇨🇳 Tax residency in China

China has two routes into tax residency. The first is domicile: individuals who habitually reside in China because of household registration, family, or economic interests are resident regardless of days. That route mostly captures Chinese nationals and long-settled families. The second is the one that matters for foreigners: 183 days or more of presence in China within a tax year (the calendar year) makes you tax resident for that year.

For a foreign nomad or expat, the calculation is therefore more mechanical than in many countries: count your days in the calendar year. What ties like an apartment or a local company change is not the entry test so much as your overall exposure: local-source income is taxable in China whether or not you are resident, and deep ties make an eventual domicile argument possible.

Residency means worldwide taxation in principle, with a top marginal rate of 45 percent on comprehensive income. That is the headline. The reality for most foreigners is softened by the six-year rule: for your first six years as a resident, foreign-source income is exempt from Chinese tax unless it is paid or borne by a China entity or individual. Note what the test is not. Remittance stopped being the test at the 2019 IIT reform, so bringing your own foreign-paid earnings into China does not make them taxable; what matters is who bears the cost of paying you. Once you pass the six-year mark as a continuous resident, full worldwide taxation applies.

The clock has a reset that is worth planning around: it starts over if you spend more than 30 consecutive days outside China in a tax year. One long trip out, taken deliberately, buys another six-year run. If you intend a long China stint, that is the single most important planning fact on this page.

On treaties: a US-China income tax treaty is in force and generally provides credit relief so the same income is not fully taxed twice; US citizens still file US returns every year regardless of where they live. For the UK, Germany, or any other home country, whether relief applies depends on whether a treaty is in force between that country and China and what it says about your income types; check the official treaty list rather than assuming coverage, because outcomes vary by country pair and income category.

Local professional help is worth it earlier here than in most countries. Engage an adviser if you are approaching 183 days in a calendar year, earning any China-source income, being paid by anything with a China entity behind it, running up against the six-year clock, or holding a Chinese company or property. Chinese individual income tax administration is document-heavy, and who pays or bears your income is exactly the point you want settled and evidenced in advance, not argued at filing time.

The short version: 183 days in a calendar year makes a foreigner resident, and the six-year rule decides whether that residency actually reaches your foreign income.
