I am not sure what the bank means by that statement? As far as I know anybody can make a payment for a bill as long as they have the payment code. Our local bank branch has just closed. A friend normally pays bills in that branch. It would be inconvenient for him to go to a different branch so I have told him I will pay it online from my account with a different bank and he can give me the cash. I haven't tried it yet but I expect to do so soon so I will report back. I don't see why you couldn't set up Direct Debit payments on your mother's account while you are in Greece and then you could simply transfer amounts to that account from your US bank if you wanted to pay them yourself. If she obtained an ID and password for her bank account and gave them to you you would be able to log onto the account and check that everything was working.

I wouldn't bank on that, no pun intended. As far as I know you can't open a Greek bank account without a Greek ΑΦΜ. The bank needs it to report bank activity to the tax office and they need the Greek tax ID in order to do that. Greek banks, like most other banks, have KYC rules, Know Your Customer, and so they would need your US Tax return to satisfy those rules, not instead of a Greek tax ID. All my UK friends who have remained tax resident in the UK have to provide a UK tax return but they still need a Greek tax ID. They may also need to satisfy FATCA rules, Foreign Account Tax Compliance Act, which could also involve your US tax return. I could be wrong. As you say, "Θα δούμε".
