I propose to take Questions Nos. 86 to 88, inclusive, together. The statutory position is that if interest is to be avoided the taxpayer must pay the tax due within two months of the due date for income tax and capital gains tax and within one month of the due date for corporation tax. The tax due is the amount charged by the assessment unless that assessment is under appeal in which event the taxpayer may specify an amount which he is prepared to pay on account pending the outcome of the appeal. Tax under appeal is not otherwise payable but if the taxpayer wishes to avoid an interest charge, the payment on account must not be less than 90 per cent of the final liability.
The vast majority of appeals are settled by agreement between the taxpayer and the inspector and the negotiations are normally conducted by correspondence. An agreement in writing disposes of the appeal and interest on the balance of tax emerging for payment will arise only if that balance is not paid within the period of two months from the date of determination of the appeal. Where there is an oral agreement between the inspector and the taxpayer the terms of that agreement must be confirmed in writing by the inspector and the taxpayer can, if he is dissatisfied, repudiate the agreement within 21 days of the issue of the letter thereby keeping the appeal open. So long as the appeal remains open interest does not accrue. It will be seen that in such circumstances any delays in reaching agreements which are attributable to the Revenue do not give rise to an interest charge.
If, however, the assessment has not been applied or if a payment on account is not specified or if the payment on account is not adequate interest will run from the original due date.
I am satisfied that the provisions of the existing law are reasonable in that, where availed of, they provide adequate protection for the taxpayer.
