China Tax Residence, CRS and FATCA: What Foreign Individuals and Families Must Know

Introduction

A foreign individual living in China — or a Chinese-connected family holding wealth across borders — now sits at the intersection of three regimes that did not exist in their current form a decade ago: China's individual income tax residence rules, the Common Reporting Standard (CRS) and FATCA. Each asks a different question, and the three answers together determine what is taxed, what is reported and to whom. This note explains the three regimes and the planning points they create for foreign individuals and cross-border families.

China tax residence: the 183-day and six-year rules

China's Individual Income Tax Law, as amended effective 1 January 2019, defines a resident taxpayer as an individual domiciled in China, or an individual without domicile who has resided in China for 183 days or more in a tax year. Residents are taxed on worldwide income; non-residents are taxed only on China-sourced income. The threshold is deceptively simple, because the 183 days are counted cumulatively across years for the purpose of a separate rule: a foreign individual without domicile who has been resident for 183 days or more in a tax year for six consecutive years becomes subject to tax on worldwide income, subject to a break rule — a single departure from China of more than 30 days in any of those six years resets the six-year count. The precise mechanics and any updated administrative rules should be confirmed against the current guidance, but the shape of the rule is what matters: a long-staying executive or family member can quietly cross into worldwide taxation.

Alongside the residence rules sits the question of domicile (住所), which is a legal concept tied to habitual residence and family and economic ties rather than to nationality or a visa. An individual can be a China tax resident by domicile even while spending substantial time abroad, which is a common surprise for families who assume a foreign passport settles the question.

CRS: China reports financial accounts to other jurisdictions

China participates in the Common Reporting Standard, the OECD's automatic exchange framework for financial-account information. Chinese financial institutions report accounts held by tax residents of other participating jurisdictions to the State Taxation Administration, which exchanges the information with the account holder's home jurisdiction; the reverse flow brings information about China tax residents' offshore accounts back to China. The practical consequence is that a foreign individual who is a China tax resident, or who holds accounts in China while resident elsewhere, should assume the account exists on the tax authority's radar in both directions.

CRS reporting turns on the account holder's tax-residence self-certification and the financial institution's due-diligence rules. A mismatch between what a person declares and what the records show — an offshore address, a foreign phone number, a pattern of foreign transfers — is exactly what triggers a deeper look.

FATCA: the United States layer

FATCA (the Foreign Account Tax Compliance Act) is the United States' separate reporting regime for US persons' accounts held outside the US. China and the United States reached agreement in substance on a Model 1 intergovernmental agreement (initialed in 2014). It has not been formally signed or brought into force, but the US Treasury treats China as having an agreement in effect, and Chinese financial institutions identify and report accounts held by US persons on that basis. For a family with US connections — a US citizen or green-card holder, or a person who meets the US substantial-presence test — FATCA reporting runs in parallel with CRS and with China's own reporting. The regimes overlap but are not identical, and a person can be reportable under one but not the other.

What the three regimes mean together

Read together, the three regimes create a compliance picture that is easy to get wrong. A foreign executive who crosses the 183-day threshold becomes a China resident taxpayer and must consider whether the six-year chain has been broken; the same person's China accounts are reported under CRS to their home jurisdiction, while any US connection adds FATCA. An offshore trust or holding company does not remove the reporting — it usually adds a layer, because the reporting looks through to the controlling person and the beneficiary. The planning that worked a decade ago, built on the assumption that a foreign account or an offshore structure was invisible, no longer holds.

Planning points

• Track the 183-day and six-year residence tests deliberately, and decide whether a break year is available and worth taking.
• Do not assume a foreign passport decides tax residence; analyze domicile and the China-sourced income rules as well.
• Keep the self-certifications on financial accounts accurate and consistent with the person's actual residence, because a mismatch is itself a red flag.
• Model CRS and FATCA exposure together — a family can be reportable under both, and the reporting is automatic.
• Before settling or restructuring a structure or a gift, confirm the China tax consequences of the transfer itself, not only the annual reporting.

How we advise

We advise foreign individuals and families on China tax residence, CRS and FATCA as one integrated question rather than three separate ones. The first step is usually a residence and account inventory: where the person is resident, which accounts exist, what has been self-certified, and where the family's wealth and beneficiaries actually sit. From there we map the reporting and the China tax exposure, and only then consider whether restructuring adds value. The goal is a position that is accurate, disclosed and durable — not a structure that collapses on its first audit.
