I presume that the system will be one whereby it will be possible to ensure that people cannot evade their tax liability by accepting payments in cash in addition to the official payment by cheque which presumably they would receive. In other words, that they cannot have one official receipt and another receipt which is unofficial in respect of an amount levied in cash and which is over and above the amount appearing on the official receipt. A large number of the people who will be availing of the services of these professional bodies will not be registered for VAT and, consequently, there will be no question of their claiming VAT back. To put it another way, their records will not be coming back to the Revenue Commissioners by way of another person claiming VAT refunds on the payment made to the professional person. In respect of these ordinary people who will be using the services of these lawyers, what provision will there be to prevent evasion by reason of the professional person seeking a cash payment in addition to the official fee?
