China's taxpayer identification for foreign individuals
China uses a Unified Social Credit Code for entities and a Resident Identity Card (RIC) number for Chinese nationals as tax identification numbers. For foreign nationals, the Taxpayer Identification Number (TIN) is typically the number on your Work-type Residence Permit or, in some cases, your passport number.
This sounds simple — and in practice, for employed foreign workers, it largely is. Your employer's HR or finance team enrols you in the Individual Income Tax system on your behalf. They register your identity document number with the State Taxation Administration (STA), file your monthly IIT withholding, and issue you an annual tax certificate. For most employed expats, they never interact directly with the tax authority at all during the first years.
When you do need to take active steps
Active registration or interaction with the State Taxation Administration becomes necessary in these situations:
- You are self-employed, a freelancer, or operating a foreign-invested enterprise rather than receiving salary through Chinese payroll.
- You have income from multiple sources in China (two employers, or employer plus rental income, or investment income from Chinese sources).
- You are approaching or have crossed the six-year continuous-residency threshold and need to assess your global income tax obligations under the six-year rule.
- You are filing for a tax deduction on qualified expenses (children's education, housing loan interest, continuing education, elderly care, major medical expenses) — these deductions require a self-filing step through the individual tax app or a tax adviser.
- You are applying for a tax clearance certificate before leaving China.
Individual Income Tax app (个人所得税 APP)
The State Taxation Administration operates an official mobile app for individual income tax management. Foreign residents can register for the app using their foreign passport or residence permit number and a Chinese mobile number. Key functions available through the app:
- View your annual IIT withholding summary from all employers.
- Declare additional deductions for qualifying expenses.
- Submit the annual IIT reconciliation (which may be required if you have multiple income sources or deductions to claim).
- Download official IIT payment certificates for use in home-country tax filings or applications.
[VERIFY: source needed — May 2026] App registration for foreign nationals requires a Chinese mobile number verified under your real identity (having completed SIM card real-name verification). A valid work residence permit and a WeChat account linked to a Chinese bank account may also be required at the registration stage — requirements have changed as the app has been updated.
For business owners and the self-employed
Foreign nationals who register a Wholly Foreign-Owned Enterprise (WFOE), a joint venture, or a representative office in China go through the company registration process at the local Administration for Market Regulation (AMR), after which the company is automatically registered for corporate income tax purposes. The foreign national's personal TIN for IIT on salary drawn from their own company works through the same mechanism as for employed workers — payroll registration with the STA.
Freelancers or consultants receiving fees from Chinese companies without a formal employment relationship are in a more complex position. Chinese companies paying service fees to foreign individuals may be required to withhold a deemed IIT amount, but practice varies. A registered tax adviser is worth consulting before structuring these arrangements.
Linking the tax number to banking
The connection between your Chinese TIN (residence permit or passport number) and your bank account becomes relevant primarily in these contexts:
- Foreign exchange conversion and overseas remittance: banks may ask for a tax clearance or registration confirmation before processing large outward remittances.
- Interest income on deposits: bank interest is subject to a 20 per cent withholding tax in China; banks file this automatically.
- High-balance accounts: banks increasingly report high-balance foreign-national accounts to the STA under CRS (Common Reporting Standard) arrangements. Your Chinese bank balance information may be shared with your home country's tax authority if your home country is a CRS participant.
