Reports

This report reflects on the implications of the evolving international tax policy landscape for international tax co-operation, and provides an update on the 2022 Report 'Tax Co-operation for the 21st Century' and the 2023 Progress Report. The principles of tax co-operation set out in those reports have become even more important in light of the implementation of the Global Minimum Tax, which took effect from the beginning of this year. This report sets out the advances being made in implementing the vision for co-operation amongst tax administrations with a specific focus on the Global Minimum Tax. It also sets out areas of tax co-operation beyond the corporate tax system looking at recent developments in the exchange of information between tax administration as well as other transparency initiatives with respect to taxation of individuals. Finally, it addresses the implications of these developments in the international tax system for developing countries with respect to both direct and indirect taxes as well as the digitalisation of tax administration. This report was prepared by the OECD to inform the discussions at the May 2024 meeting of G7 Finance Ministers and Central Bank Governors, at the request of the G7 Italian Presidency.

This guide builds on the Reform Management Fundamentals: Setting up a Reform Program reference guide to provide an understanding of recognized good practices to ensure the success of implementing tax administration reform programs. It presents proven management practices for implementing reform projects that have been applied by tax administrations around the world. It is part of a series of Virtual Training to Advance Revenue Administration (VITARA) reference guides that have been developed based on the content of the VITARA online modules.

This reference guide provides a good grounding in what tax administration reform is, why it is important, what is involved in implementing it, and who should be involved in the reform process. The materials covered in this reference guide are designed to cover the key practices that have been proven to assist the management of reform efforts and will give the tax administrations the best chance of success in developing and implementing reform programs. This guide is divided into five chapters highlighting key terms and definitions, processes to develop and manage a reform program, and how to plan and manage a reform project. It is part of a series of Virtual Training to Advance Revenue Administration (VITARA) reference guides that have been developed based on the content of the VITARA online modules.

This report compiles comparable tax revenue statistics over the period 1990-2022 for 27 Latin American and Caribbean (LAC) countries. It provides harmonised data on the level and structure of tax revenues based on the OECD classification of taxes, thereby enabling comparison of national tax systems on a consistent basis, both across the region and with other economies globally. The report includes two special features: one examines fiscal revenues from non-renewable natural resources in the LAC region in 2022 and 2023, while the second calculates equivalent fiscal pressure in the LAC region. The publication is jointly undertaken by the OECD Centre for Tax Policy and Administration, the OECD Development Centre, the Inter-American Center of Tax Administrations (CIAT), the Economic Commission for Latin America and the Caribbean (UN-ECLAC), and the Inter-American Development Bank (IDB).

This annual publication provides details of taxes paid on wages in OECD countries. This year’s edition focuses on fiscal incentives for second earners in the OECD and how tax policy might contribute to gender gaps in labour market outcomes. For the year 2023, the report also examines personal income taxes and social security contributions paid by employees, social security contributions and payroll taxes paid by employers, and cash benefits received by workers. It illustrates how these taxes and benefits are calculated in each member country and examines how they impact household incomes. The results also enable quantitative cross-country comparisons of labour cost levels and the overall tax and benefit position of single persons and families on different levels of earnings. The publication shows average and marginal effective tax rates on labour costs for eight different household types, which vary by income level and household composition (single persons, single parents, one or two earner couples with or without children). The average tax rates measure the part of gross wage earnings or labour costs taken in tax and social security contributions, both before and after cash benefits, and the marginal tax rates the part of a small increase of gross earnings or labour costs that is paid in these levies.

A key part of the OECD/G20 BEPS Project is addressing the tax challenges arising from the digitalisation of the economy. In October 2021, over 135 jurisdictions joined a ground-breaking plan to update key elements of the international tax system which is no longer fit for purpose in a globalised and digitalised economy. The Global Anti-Base Erosion (GloBE) Rules are a key component of this plan and ensure large multinational enterprise pay a minimum level of tax on the income arising in each of the jurisdictions where they operate. More specifically, the GloBE Rules provide for a co-ordinated system of taxation that imposes a top-up tax on profits arising in a jurisdiction whenever the effective tax rate, determined on a jurisdictional basis, is below the minimum rate. The Commentary to the GloBE Rules was originally released by the Inclusive Framework in March 2022. The Commentary explains the intended outcomes under the GloBE Rules, clarifies the meaning of certain terms and illustrates the application of the rules to certain fact patterns. This Consolidated Commentary incorporates Agreed Administrative Guidance that has been released by the Inclusive Framework since March 2022 up until December 2023. It provides tax administrations and taxpayers with guidance on the interpretation and application of the GloBE Rules in order to promote a consistent and common interpretation and application of those that will facilitate coordinated outcomes for both tax administrations and MNE Groups.
