We are British retirees and do not earn money in Malta and therefore have not registered for tax and do not have a Maltese bank account. Our pensions are paid into our UK bank account. All our purchases are paid for with a British credit card and settled from a British bank account.
Because we recently asked our British bank to post communications to our address in Malta, they have forwarded a form to us asking us to declare that we are non-residents in the UK and want us to declare a Maltese tax number (a copy of this tax document to be certified by a local notary).
Does anyone know if there is a legal obligation for us to provide this to them, is it a UK HMRS condition that this has to be done. Help please.
