I have sometimes wondered about the possibilities of opening / keeping accounts in ireland if i should leave the country and give up my address here.. I think the UK and ireland might have similar policies ?!
I still have several accounts in the UK from when I was living there,
I believe to open an account it is absolutely necessary to have an address there at least (and one bank told me if i give up my address in the UK they won't maintain the account..)
the one bank used to pay me interest with no tax deducted,
after some years they told me i'd have to declare my agreement to pay
tax to maintain the account, then i found out that i can still get the tax back from the UK tax office after filling in a non-resident tax claim form.
I think this should be similar for Ireland..?!
