Employment income
Japan and China have a longstanding tax treaty. Japanese nationals in China pay Chinese IIT on China-sourced income; Japan provides a credit for Chinese tax paid. Japan's exit tax (a deemed disposal tax on unrealised gains when a high-net-worth individual becomes non-resident) can be relevant for Japanese nationals departing for China.
Pension and retirement income
[VERIFY: source needed — May 2026] Japanese national pension (kosei nenkin) and kokumin nenkin income received while in China may have specific treaty treatment.
Key notes for Japan nationals in China
Japan has a large business and manufacturing presence in mainland China. Japanese company postings to China are very common; HR departments in Japanese companies operating in China typically have experience managing the Japan-China tax position.
How to use this information
This guide provides a starting point. For practical application:
- Locate the official treaty text (published by both countries' tax authorities and by the IBFD or PwC's worldwide tax summaries).
- Identify a tax adviser who holds qualifications or active practice experience in both Japan tax law and Chinese IIT.
- Bring your specific income sources, residency timeline, and family situation to the adviser — treaty application is always fact-specific.
