This study was produced by the Tax Policy and Statistics Division of the OECD Centre for Tax Policy and Administration, with the financial support of the Korea Institute of Public Finance (KIPF).
The report was led by Sarah Perret and written by Bethany Millar-Powell and Sarah Perret. The authors would like to thank Bert Brys and David Bradbury for their guidance and feedback throughout the project. The report also benefited from significant input from Michael Stemmer on the simulations included in Chapter 2 and from very helpful comments from Pierce O’Reilly and Alastair Thomas. The authors would also like to thank Carlotta Balestra for supplying the underlying data used in Chapter 1 based on the OECD Wealth Distribution Database and for providing feedback on Chapter 1, as well as Sebastian Königs for his review of Chapter 1. The authors are also very grateful to Carrie Tyler, Natalie Lagorce, Julien Dubuc, Hazel Healy and Karena Garnier for their support with communications and formatting, and to Violet Sochay for her assistance with administrative matters. In addition to OECD colleagues, the authors would like to acknowledge Emma Chamberlain (OBE CTA Barrister, Pump Court Tax Chambers) and Daniel Waldenström (Professor, Research Institute of Industrial Economics – IFN Stockholm) for their thorough review and comments on the first draft of the report. Ricardo Guerrero (PhD candidate, King’s College London) provided some background research as input to Chapter 2.
The report would not have been possible without the significant involvement of the delegates of Working Party No.2 on Tax Policy Analysis and Tax Statistics (WP2) who replied to the “OECD Questionnaire on Inheritance, Estate, and Gift Taxes”, upon which the analysis in the report is largely based, and provided feedback on the draft report at various stages.
This report was approved by WP2 delegates on 15 March 2021 and by the delegates of the Committee on Fiscal Affairs (CFA) on 14 April 2021. The report was prepared for publication by the OECD Secretariat.
