I am advised by the Revenue Commissioners that the correspondence in question is used in very limited circumstances for the purpose of establishing whether a particular person is accurately recorded in their tax register. Where the individual does not have a tax registration, the reply to the correspondence assists Revenue in assessing whether or not the individual should have one. The response to the correspondence also assists Revenue in matching information accurately to an individual in Revenue records.
Such a questionnaire is issued only where officers in the Revenue District are not fully satisfied that they have been able to match information accurately with an individual's tax registration, despite extensive searching of Revenue records.
I am further advised that Revenue will contact the person in question again to clarify they information they require.
