Employment income
Spain taxes residents on worldwide income. Spanish nationals in China pay Chinese IIT on China-sourced income; Spain provides a credit for Chinese tax paid. The Beckham Law (régimen especial de trabajadores desplazados) may apply to Spanish nationals arriving in Spain from China for certain highly-paid positions, but this is the reverse direction of most China postings.
Pension and retirement income
[VERIFY: source needed — May 2026] Spanish state pension received abroad may be subject to Spanish withholding tax. Confirm with Agencia Tributaria.
Key notes for Spain nationals in China
Spain is the largest source of direct investment from Latin America's Spanish-speaking community into China (as a transit country), though Spanish nationals themselves are not among the largest expat groups in China.
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 Spain tax law and Chinese IIT.
- Bring your specific income sources, residency timeline, and family situation to the adviser — treaty application is always fact-specific.
