Tax Administration 2015 is a comprehensive survey of tax administration systems, practices and performance across 56 advanced and emerging economies (including all OECD, EU, and G20 members).

This report is the ninth edition of the OECD's Tax Administration Series. It provides internationally comparative data on aspects of tax systems and their administration in 59 advanced and emerging economies.

This report provides an overview of best practices in tax debt management, with a particular emphasis on how to better differentiate debtors when deciding how to best secure payment and what can be done to ensure that payment issues are considered earlier in the compliance and collection process.

This edition of the series provides internationally comparative data on aspects of tax systems and their administration in 55 advanced and emerging economies. It covers all jurisdictions that were members of the OECD's Forum on Tax Administration (FTA) at the launch of the 2016 tax administration survey. In addition, it includes information on Peru, that became a member of the FTA in March 2017; the non-FTA jurisdictions that are members of the European Union (i.e. Bulgaria, Croatia, Cyprus, Malta, and Romania); as well as Morocco (which increases the reports' geographical coverage).

This report examines the relationship between large business taxpayers and revenue bodies, five years on from the publication of the FTA’s Study into the Role of Tax Intermediaries.

Health at a Glance provides a comprehensive set of indicators on population health and health system performance across OECD members and key emerging economies. This edition has a special focus on the health impact of COVID-19 in OECD countries, including deaths and illness caused by the virus, adverse effects on access and quality of care, and the growing burden of mental ill-health.

A Tax Control Framework (TCF) is the part of the system of internal control that assures the accuracy and completeness of the tax returns and disclosures made by an enterprise. The TCF plays a central part in bringing rigour to the co-operative compliance concept. The objective of this report is to provide guidance that is meant to be helpful for businesses to design and operate their TCFs and for revenue bodies to adjust the risk management strategy for an individual large business in the context of a (voluntary) co-operative compliance relationship as laid out in the FTA report Study into the Role of Tax Intermediaries (OECD, 2008), the 2013 report, and the September 2013 BIAC Statement of Tax Principles for International Business (see Annex A). The broad conclusions of this report are that when the tax control framework of a multinational enterprise participating in cooperative compliance programme is determined to be effective, and when the enterprise provides complete disclosures that include relevant information and tax risks and is transparent to the revenue body, the extent of reviews and audits of the returns submitted to it can be reduced significantly. In these circumstances, the revenue body may rely on the returns submitted to it and trust that uncertain tax positions and other problematic tax positions taken in that return will be brought to its attention.
