Taxes for expats

Individual Income Tax (IIT) basics

China's Individual Income Tax applies to all income earned within China and, for tax residents, to worldwide income. Rates are graduated from 3% to 45% across seven brackets:

Before the bracket applies, the following are deducted: a standard deduction of ¥60,000 per year (¥5,000 per month), mandatory social-insurance contributions, and housing provident fund contributions. The result is your taxable income.

A single expat earning ¥300,000 per year in salary would pay roughly ¥38,000–¥45,000 in IIT after standard deductions and social insurance, landing in the 20–25% marginal bracket. A practical calculator is available through the State Taxation Administration (STA) app and on most major Chinese bank apps [VERIFY: source needed — May 2026].

Residency tests

Where you fall on the residency spectrum dictates your tax exposure:

• Non-resident (under 183 days in China in the calendar year): taxed only on China-sourced income, at a flat monthly withholding. No annual reconciliation required.
• Tax resident (183+ days in the calendar year): taxed on worldwide income. Must file the annual reconciliation (March–June). This is most working expats.
• The 6-year rule: foreign nationals who become tax residents are not taxed on foreign-sourced income not remitted to China for the first six consecutive years of residency. If you are abroad for 30 or more continuous days within any of those six years, the clock resets to zero.

The reset provision is widely used: many multinational employees arrange a home-country work trip of 30+ consecutive days in year five or six to restart the timer. This should be planned with an adviser rather than improvised — the STA records entry and exit dates via passport checks and can review historical records.

Day-counting runs on the calendar year (1 January – 31 December), not a rolling twelve months. Partial days in China count as full days.

The 183-day count in practice

Any day on which you are physically present in China, even for a few hours, counts. Transiting through Chinese airports on the airside does not count (since you have not cleared immigration). Crossing via land border for a same-day visa run does count.

If your situation is borderline — say 175–185 days — keep evidence: flight boarding passes, hotel receipts, and a personal calendar with a day-by-day log. Tax disputes about residency are not common, but they do happen, especially on departure when authorities review your overall file.

Tax-treaty implications

China has double-taxation treaties with most major economies, including the USA, UK, France, Germany, Australia, Canada, Singapore, and many others. Hong Kong has a separate arrangement under the Comprehensive Double Taxation Arrangement (CDTA).

Treaty provisions typically cover:

• Which country has primary taxing right on each income category (employment, dividends, royalties, pensions, etc.).
• Tie-breaker rules for dual-residency situations (e.g., you are tax-resident in both China and your home country simultaneously).
• Reduced withholding rates on cross-border dividends, interest, and royalties — these can reduce Chinese withholding from 10% to 5–7% in some treaties.
• Exclusions for certain government employees, students, and researchers.

Americans face a specific complication: the US taxes its citizens and permanent residents on worldwide income regardless of where they live, meaning US expats in China may owe tax in both jurisdictions. The US-China tax treaty helps at the margins, but many American expats engage a specialist dual-filer accountant [VERIFY: source needed — May 2026].

Allowable deductions

Beyond the ¥5,000/month standard deduction, specific deductions reduce taxable income:

Major medical expenses (over ¥15,000 in a year) and charitable donations to approved organisations are also deductible within annual limits.

Foreign allowances — housing, schooling, language training — were previously exempt for expats, but these were phased into the standard deduction system from 2022. Some transitional arrangements may still apply to pre-2022 employment contracts. Confirm your situation with your HR department or a tax adviser [VERIFY: source needed — May 2026].

Annual reconciliation (汇算清缴)

The annual reconciliation runs from 1 March to 30 June for the previous calendar year. Who must file:

• Comprehensive income exceeding ¥120,000 in the year.
• Unpaid or overpaid IIT from multiple employers.
• Claiming additional deductions (rent, mortgage, dependents) not already declared monthly.
• Foreign-sourced income received while a tax resident.

The process: download the STA IIT app (个人所得税 app), log in with your ID number and phone number, confirm pre-filled income data from your employer(s), add deductions, and submit. Refunds are typically paid directly to your bank account within 5–15 working days. Additional tax owed is paid through the app or via online banking [VERIFY: source needed — May 2026].

Most single-employer salaried expats with clean finances can complete the reconciliation unassisted in 20–30 minutes. Multi-source-income situations, equity grants, and foreign income take longer and often warrant professional help.

Social insurance contributions

Employers and employees both contribute to five mandatory social insurance funds (pension, medical, unemployment, work-injury, maternity) plus the housing provident fund. Rates vary by city but employee contributions typically run 10–12% of salary [VERIFY: source needed — May 2026]. These contributions are deductible from IIT.

Foreign employees at Chinese companies are generally required to contribute. Foreign employees at foreign-invested enterprises (FIEs) or on secondment from overseas may be exempt under bilateral social-security agreements (the UK, Germany, South Korea, Japan, and several others have such agreements with China [VERIFY: source needed — May 2026]). If your employer has been handling this, verify the arrangement when you consider leaving — unpaid contributions can complicate your departure.

Departing China

Leaving permanently adds tax obligations:

1. **File the annual reconciliation** for the current year, even if the 1 March – 30 June window has not opened. An early out-of-window filing is permitted when departing [VERIFY: source needed — May 2026]. 2. **Count all income through your final day:** last salary, any bonus, equity vesting, severance, and unused leave payouts all count toward the year's IIT. 3. **Deregister your tax ID** with your local tax bureau. You will need your passport, work permit, residence permit, reconciliation confirmation, and employer deregistration paperwork. Some bureaus require your employer to file a deregistration certificate on your behalf. 4. **Social insurance clearance:** confirm with HR that all contributions are settled and that there are no outstanding arrears. 5. **Bank fund repatriation:** repatriating large sums (typically over USD 50,000 equivalent [VERIFY: source needed — May 2026]) requires proof of tax compliance at your bank.

Allow four to six weeks before your final exit date for the full departure procedure. Starting it the week before your flight is asking for a very stressful final fortnight in China.

When to hire a tax agent

For routine employment situations, the STA app and your HR payroll team are sufficient. Consider a professional accountant or tax adviser if you:

• Hold equity in a Chinese or foreign company.
• Receive income from multiple sources or jurisdictions.
• Are approaching year five or six of residency (6-year rule planning).
• Are a US citizen (dual-filer complexity).
• Are a business owner, director, or independent contractor.
• Are departing and have complex assets to unwind.

Major accounting firms (Big 4 and several mid-tier firms) operate in all tier-1 cities and have dedicated expatriate tax practices. Fee estimates: ¥3,000–¥8,000 for a straightforward annual filing; ¥15,000–¥50,000 for complex multi-jurisdiction situations [VERIFY: source needed — May 2026].
