Employment income
South Korea and China have a close economic relationship and significant bilateral treaty infrastructure. Korean nationals in China pay Chinese IIT on China-sourced income; Korea provides a credit for Chinese tax. The large Korean manufacturing and business presence in mainland China means Korean company HR departments have well-developed processes for managing this.
Pension and retirement income
[VERIFY: source needed — May 2026] Korean national pension (NPS) contributions and income may be subject to specific treaty provisions when received abroad.
Key notes for South Korea nationals in China
South Korea is one of the largest sources of foreign business investment in mainland China, particularly in manufacturing. The treaty is actively used and Korean tax authorities have significant experience with cross-border China situations.
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 South Korea tax law and Chinese IIT.
- Bring your specific income sources, residency timeline, and family situation to the adviser — treaty application is always fact-specific.
