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
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.
