There seems to be something going on with the banks updating their records, as we have also just been required to go through all that. We are also non-tax resident, but retired, and we have been asked to give our bank a copy of our UK pension statements as proof of income in the UK. We were also required to sign a fresh declaration that we have no employment or income in Greece; to confirm our passport details and address and contact details in Greece and the UK. It would be nice to think that this is all being linked with the Greek tax authorities to make the annual tax return process even smoother .. but I'll believe that when it happens. The bank official was a bit vague about why this is being done, but said all the ex-pats were being contacted for this information, so I wonder if it has anything to do with Brexit. I think the bottom line, Kriticat, is that they want proof that you can afford to own your property in Greece without having any income here, so as Warwick says, a P60 should do the trick.
