This is definitely playing with fire.
Enough said
it’s the old common law concept of “domicile” that doesn’t reconcile with civil law “residence”, and leaves the door open to a number of interpretations. Which will always be favorable to the taxman, you betcha.Do you have a source for the claim that Spain doesn't consider people who are resident in Cyprus as non-resident if they claim the non-domicile exemption? It's the second time I hear about it and when I've checked it with lawyers in the alleged countries where this is the case, none have been able to confirm it.
What you're saying is that you can spend 365 days per year in Cyprus, claim non-domicile exemption, and still be taxed as if resident in Spain. From the lawyers I've spoken with, that isn't the case.
Anyway a non dom is supposed (in common law) not to have the intention to reside permanently in the host country, and that is enough to cause troubles.
Sorry it is an oversimplified explanation, there are many articles and case law out there that analyze all the details, it’s complex stuff and dangerous too. Better to play it safe.
