China’s tax system has undergone significant changes to meet the demands of its rapidly expanding economy and the complexities of global financial integration. One of the most notable adaptations is the “six-year rule“. This rule says that after six consecutive years of living in China for 183+ days in each year, an expat becomes liable to be taxed on their worldwide income.

In this article, we explain how the 6 year rule works and what the exceptions to this rule are. “Since the six-year count reset in 2019, individuals who have lived continuously in China since then should review their position in 2026, as worldwide income taxation may apply from 2027 onward.

Overview of the Six-Year Rule

In China’s tax system, the Six-Year Rule is a critical component that influences the tax liabilities of individuals working within the country. It determines tax residency and the associated taxation of an individual’s global income.

Concept of the Six-Year Rule

The Six-Year Rule in China gives criteria under which individuals are considered tax residents. If an individual, either Chinese or foreign, resides in China for 183 days or more per year for six consecutive years, they are deemed a tax resident. This residency status has significant implications for their taxation responsibilities, including the taxation of their worldwide income.

Determining Tax Residency

The number of days spent in China is tallied over six years to determine if someone is a tax resident under the Six-Year Rule. Domicile, in this context, refers to living in China due to legal, family, or economic ties. Crucially, if an individual leaves China for over 30 consecutive days in any year, the six-year count resets. Expatriates and Chinese nationals must carefully monitor their presence in the country to understand their tax residency status.

Criteria	Requirement
Days in China	183 days or more per year
Consecutive Years	6 years
Reset Condition	Leaving China for more than 30 consecutive days in any year

Under China’s Six-Year Rule, tax treatment depends on how many days an individual spends in China each year, whether they have reached six consecutive years of residence, and whether they take a qualifying break abroad. Individuals who spend fewer than 183 days in China in a calendar year are generally treated as non-residents and are taxed only on China-sourced income. Those who spend 183 days or more in China but have not yet completed six consecutive years are typically considered tax residents, although foreign-sourced income may remain exempt until the rule is triggered. Once an individual has spent 183 days or more in China for six consecutive years without any absence of more than 30 consecutive days, worldwide income may become subject to Individual Income Tax from the seventh year onward. This is especially relevant for expatriates working remotely while based in China. Importantly, if the individual leaves China for more than 30 consecutive days in any year, the six-year count resets, which can defer worldwide income taxation. Since the timetable reset in 2019, expatriates who have remained continuously in China should review their position in 2026, as worldwide income exposure could begin from 2027 if no qualifying break is taken. Expats in regions such as the Greater Bay Area may also benefit from local individual income tax subsidy policies.

Tax Implications for Individuals

Once tax residency is determined, an individual must adhere to the Individual Income Tax (IIT) law and report worldwide income for taxation. The tax implications for individuals under the Six-Year Rule can be significant, as residents are subject to China’s taxation on their global earnings. In contrast, non-residents are taxed only on their China-sourced income. Therefore, those qualifying under the Six-Year Rule must plan their tax strategy carefully to comply with local tax regulations.

Annual Reconciliation and Reporting

China’s Individual Income Tax Law mandates that taxpayers carry out an annual reconciliation of their taxes to account for various sources of income, including worldwide and China-sourced income. During this period, taxpayers should report their annual earnings to the State Taxation Administration, which may entail additional payment or refund of taxes. Foreign individuals, in particular, must accurately disclose both their foreign-sourced income and China-sourced income to comply with tax obligations and benefit from applicable exemptions.

Reporting Requirement	Description
Annual Earnings Report	Report all sources of income to the State Taxation Administration
Income Sources	Worldwide and China-sourced income
Potential Outcomes	Additional payment or refund of taxes

Strategic Tax Planning for Foreign Individuals

Foreign individuals working in China can benefit from strategic tax planning, especially concerning the Six-Year Rule, which opens opportunities for tax breaks on their foreign-sourced income. Through careful tax planning, they can minimize their total tax liability by understanding the distinctions between China-sourced and foreign income. This involves informed decision-making on tax filing, employment arrangements, and leveraging potential exemptions.

Importantly, individuals who have been in China continuously since 2019 should seek advice in 2026 on whether a 30+ day break is needed to reset the residency clock before 2027.

The six-year rule allows foreign expatriates working in China to exclude 90% of gross income from Chinese tax if they have not resided in China more than six months in any given year—a substantial benefit for short-term assignees, but proper tax residency determination requires detailed tracking of presence days and calendar alignment. Miscalculating residency can result in back-tax liability on 100% of income. MSA Asia tracks expatriate tax status and optimizes annual planning. Speak with our advisors for China tax advisory.
