The figures quoted by the Deputy are not representative of the overall yield from the Revenue audit and investigation programmes in 1992. They ignore cases where the tax returns were accepted, as submitted, with no additional tax liability arising. In addition, the overall yield is distorted by a number of very large settlements in the period.
The total number of audits, covering both the self-employed and companies, completed under the self assessment audit programme for the calendar year 1993 — the latest period for which figures are available — was 2,537 yielding an average of £7,765 per case. This compares with audit figures of 770,1,496 and 2,482 cases for the three preceding years, 1990, 1991 and 1992.
Self assessment audits are only one element of the total Revenue audit programme which also includes PAYE employers, VAT, relevant contracts tax and investigation branch audits. Taking account of these additional programmes the total revenue audit programme for 1993 involved 24,000 cases, yielding an average of £4,250 per case.
Under the various Revenue audit programmes, cases are selected for audit and investigation following a detailed screening of the returns as filed. The selection procedures are based on certain perceived defects in the tax return and supporting accounts and/or by reference to information arising from external and other sources. The method of selection does, however, include a small proportion picked at random. This is considered necessary to further encourage compliance. Because of this inherent bias in the selection process, the results from cases audited or investigated cannot, therefore, be regarded as indicative of the overall level of compliance among the taxpaying community at large.
The Government and the Revenue Commissioners are conscious of the need for an active audit programme in the context of self assessment. The level of audits is kept under constant review to ensure compliance and to deter tax evasion. An indication of the commitment of the Government and the Revenue Commissioners to this end is the increase in the numbers of officers allocated to the various audit, investigative and compliance programmes from 212 in 1988 to a present level of some 600.
The number of cases impacted will vary from year to year depending on the issues involved and the types of cases forming the focus of the programmes in any particular year. Overall I consider the present audit/investigation programmes to be operating satisfactorily.
