AH0175 - Postponement applications: Interest on tax paid late and SA surcharge


Interest is payable on tax and Class 4 NIC paid late including tax and Class 4 NIC which have been the subject of a postponement application. It is therefore important that taxpayers are advised of the possible consequences of not making a realistic payment on account when an assessment is under appeal. The notes issued with returns and notices of assessment appeals all carry interest warnings. The taxpayer is clearly told that interest where due, will be charged on late payment.

If the taxpayer queries the amount of interest he is being asked to pay he/she should be referred to the appropriate Accounts/Receivables Office.

Interest is charged as a matter of course when tax eventually found to be payable following an appeal to the Commissioners or to the Courts is paid after the date indicated by the statutory rules. If the subject of the appeal was a point which has arisen in other cases concurrently, the hearing may have been deferred while a case is chosen for proceedings to go forward as a test case. If an appeal is awaiting the result of a test case and the taxpayer applies to postpone payment of all or part of the disputed tax explain to the taxpayer, when accepting the application, that if the tax is eventually found to be payable the normal rules governing the charging of interest will apply.

If an SA charge is postponed (stoodover) the reckonable date for calculating interest is not affected but the due date is deferred. The deferred due date is used for calculating any surcharge.
