Carbon pricing very effectively encourages the shift of production and consumption choices towards low and zero carbon options that is required to limit climate change. Are countries using this tool to its full potential? This report measures the pricing of CO2-emissions from energy use in 44 OECD and G20 countries, covering around 80% of world emissions. The analysis takes a comprehensive view of carbon prices, including fuel excise taxes, carbon taxes and tradable emission permit prices. The 'carbon pricing score' measures how close the 44 countries, together as well as individually, are to the goal of pricing all energy related carbon emissions at current and forward-looking benchmark values for carbon costs. The report highlights the structure of effective carbon rates across countries and sectors in 2018 and discusses change compared to 2012 and 2015. It also provides an outlook on recent trends in emissions trading in China and the European Union.

This report compiles comparable tax revenue statistics over the period 1990-2019 for 27 Latin American and Caribbean economies. Based on the OECD Revenue Statistics database, it applies the OECD methodology to countries in Latin America and the Caribbean to enable comparison of tax levels and tax structures on a consistent basis, both among the economies of the region and with other economies. This 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 (ECLAC) and the Inter-American Development Bank (IDB). The 2021 edition is produced with the support of the EU Regional Facility for Development in Transition for Latin America and the Caribbean, which results from joint work led by the European Union, the OECD and its Development Centre, and ECLAC.

The report provides an overview of the tax measures introduced during the COVID-19 crisis across almost 70 jurisdictions, including all OECD and G20 countries and 21 additional members of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting. It examines how tax policy responses have varied across countries and evolved over the last year. It also offers some guidance as to how tax policy responses could be adapted to address the short-term challenges countries face and outlines future work that the OECD will be undertaking to help countries reassess their tax and spending policies in the longer run.

This report aims at assisting tax authorities in designing and implementing an effective Value Added Tax/Goods and Services Tax (VAT/GST) policy response to the growth of the sharing and gig economy. The rise of this phenomenon, powered by digital platforms, has transformed a number of industries within just a few short years. It involves large numbers of new economic operators (often private individuals), who monetise (often) underutilised goods and services by offering these, via digital platforms, for temporary ('shared') use by primarily private consumers. Questions have been raised whether existing VAT/GST policy and administration frameworks are sufficiently capable of dealing with this new economic reality notably with a view to protecting VAT/GST revenue and minimising economic distortions. This report sets out the core components of a comprehensive VAT/GST policy strategy for tax authorities to consider in response. It analyses the key features of the sharing and gig economy and its main business models; identifies the associated VAT/GST challenges and opportunities; and presents a wide range of possible measures and approaches to support an effective policy response. This includes detailed guidance on the possible role of digital platforms in facilitating and enhancing VAT/GST compliance in the sharing and gig economy.

Under Action 14, countries have committed to implement a minimum standard to strengthen the effectiveness and efficiency of the mutual agreement procedure (MAP). The MAP is included in Article 25 of the OECD Model Tax Convention and commits countries to endeavour to resolve disputes related to the interpretation and application of tax treaties. The Action 14 Minimum Standard has been translated into specific terms of reference and a methodology for the peer review and monitoring process. The peer review process is conducted in two stages. Stage 1 assesses countries against the terms of reference of the minimum standard according to an agreed schedule of review. Stage 2 focuses on monitoring the follow-up of any recommendations resulting from jurisdictions' Stage 1 peer review report. This report reflects the outcome of the Stage 2 peer monitoring of the implementation of the Action 14 Minimum Standard of Malta, which is accompanied by a document addressing the implementation of best practices.
