Inland Revenue research project

About 400 high-wealth individuals have been selected to take part in a statistical research project to help NZ Inland Revenue fill a gap in their knowledge of effective tax rates relative to economic measures of income.

nz inland revenue ird copyThe project will use household income as the unit of analysis, so people taking part will be asked for financial information about themselves and their dependent children. Their partners will also be asked for financial information.

Individuals will be legally required to provide this information.

Participants will be asked for information in three stages:

  1. In November 2021, individuals will be asked to provide details of their partner and dependent children. This will provide accurate information about whose income will be included in the analysis.

  2. In January 2022, individuals and their partners will be asked for information about the entities and business undertakings they have an interest in. Individuals will also be asked about the entities their dependent children have an interest in.

  3. In May 2022, individuals and their partners will be asked to provide further information to help calculate measures of income for IRD's analysis.

All the information provided will be kept confidential and will not be used to reassess anyone’s tax liability.

The research will be published in a report to be made public in mid-2023. The project will not make any policy recommendations, but the analysis will improve future tax policy advice.

Inland Revenue has contacted the individuals’ tax agents to let them know their clients who have been selected to take part in the study.
