The total number of tax convictions under the Tax Administration Act 1994 in each calendar year.
The information is supplied by the Ministry of Justice and may differ marginally from other analyses due to timing and differences in counting cases involving:
- multiple defendants
- multiple offences
- alternative charges, and
- representative charges.
However, the numbers are broadly representative of Inland Revenue's prosecution activity.
Due to changes in the methodology, the figures before 2013 differ from those published previously.
