China → Portugal · tax
In plain termsOne treaty, two systems. Portugal counts 183 days or a habitual home; China keeps its six-year rule and domicile test. The DTA breaks a tie — it does not erase the home rules.
There is a treaty — in force since 2000
An in-force China–Portugal DTA exists (yes), signed 1998-04-21 and in force from 2000-06-08. Portugal's own door is more than 183 days — read Portugal tax residency.
Dual residence — a full cascade
Art 4 picks one: permanent home → centre of vital interests → habitual abode → nationality → mutual agreement.
China-side traps — Portugal does not delete them
Client trapChina's six-year rule, domicile concept and hukou clearance stay in force (yes). Compare the live beachhead pair: China → Vietnam · tax.

Common questions
Is there a China–Portugal tax treaty?
Yes. The Agreement was signed on 21 April 1998 and entered into force on 8 June 2000. It sets reduced withholding rates and an Article 4 residence tie-breaker.
How does the dual-residence tie-breaker work?
Article 4 runs the full OECD cascade: permanent home → centre of vital interests → habitual abode → nationality → competent-authority mutual agreement.
Does moving to Portugal switch off Chinese rules?
No. China's six-year rule for worldwide taxation of residents, the domicile concept and hukou-related clearance are domestic and survive the move.
