The Revenue spokesman said that the Division "monitors tax compliance through risk identification, assessment and evaluation programmes and processes that are supported by data analytics and by the interrogation of both taxpayer and third-party information".
"In line with Revenue's overall approach to managing compliance, the appropriate intervention is undertaken following appraisal of the risk factors identified in each case."
The Revenue spokesman said that there are currently 125 people at various grades working in the division across the full range of functions and responsibilities undertaken by the division.
