This hint may help anyone struggling with inputting information about foreign accounts - not bank or building society accounts, but ISAs or share accounts (and maybe other type which I don't have).

If, like me, you accidently delete previous years' declared entries for foreign accounts, you cannot retrieve them and have to enter the information again.  If you are declaring ISAs or share accounts you are now asked for far more detail than before.  If you give any incorrect/inappropriate information you cannot proceed to the next item.  So, after entering the date of opening the account, account number and name address of the holding company, you are then asked for the duration and completion date of the contract.  In the completion date box, simply write 'Viager' and it's like saying 'Abracadabra'.
