The paper assesses the impact of the global minimum tax (GMT) on the taxation of multinational enterprises (MNEs), based on a comprehensive dataset capturing the global activities of large MNEs. It has four key findings. First, the GMT substantially reduces the incentives to shift profits. Second, the GMT is estimated to very substantially reduce low-taxed profit worldwide through lower profit shifting and top-up taxation. Third, the GMT is estimated to increase CIT revenues. Finally, the GMT is estimated to reduce tax rate differentials across jurisdictions with potential impacts on the allocation of investment and MNE activity.

The paper analyses the current system of environmental taxation and environmental expenditure in Ukraine, identifies issues in the way environmental tax policy is currently designed and implemented and highlights main areas where environmental taxation and expenditure could be improved. It uses data on environmental tax revenue and budgets from expenditure reports of the State Treasury Service of Ukraine over the period 2010 - 2020. Where available, preliminary data for 2021 were also included. The paper aims to support the government of Ukraine in reforming environmental taxation and public funding for environmental protection. Ukraine’s Post-War Recovery and Reconstruction Plan outlines ambitious plans for reform, including in the environmental domain. It envisions restructuring the current environmental tax system, expanding it to energy and transport and harmonising it with that of the European Union. It also foresees an analytical study systematising current taxes and payments in line with Eurostat classification standards. This paper can support these efforts.

Under the BEPS Action 5 minimum standard, members of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS) have committed to counter harmful tax practices with a focus on improving transparency. One part of the Action 5 minimum standard is the transparency framework for compulsory spontaneous exchange of information on certain tax rulings. The exchange on tax rulings is a critical tool in improving access of tax administrations to information relevant to assess the corporate tax affairs of their taxpayers and to efficiently tackle tax avoidance and other BEPS risks. Over 140 countries and jurisdictions participate in the Inclusive Framework on BEPS and take part in the peer review process to assess their compliance with the transparency framework. Specific terms of reference and a methodology have been agreed for the peer reviews, focusing the assessment on five key elements: information gathering process, exchange of information, confidentiality of the information received, statistics on the exchanges on rulings, and transparency on certain aspects of intellectual property regimes. This report reflects the outcome of the seventh annual peer review of the implementation of the Action 5 minimum standard.

Dividend stripping is a type of fraud that is committed through a complex mechanism of trading, selling and repurchasing shares over a certain period to unlawfully avoid payment of dividend taxes, or to claim unjustified tax reimbursements. Dividend stripping in its many forms poses a great challenge to the tax bases of numerous jurisdictions and may create market distortions that corrode the integrity of the financial system. This report is intended to raise awareness of dividend stripping frauds and provides a number of recommendations for countries around recognising the risk, improving domestic co-ordination and expanding international co-operation. In particular, tackling dividend stripping requires strong domestic inter-agency co-ordination and international co-operation, as well as the sharing of information between jurisdictions. Countries may therefore wish to prepare targeted actions and comprehensive strategies against this phenomenon, including not only tax administrations and law enforcement, but also financial regulators and supervisory authorities, as well as anti-money laundering competent authorities. Legislative changes may also be required in some cases.

Data on government sector receipts, and on taxes in particular, are basic inputs to most structural economic descriptions and economic analyses, and they are increasingly used in economic comparisons. This annual publication gives a conceptual framework to define which government receipts should be regarded as taxes. It presents a unique set of detailed and internationally comparable tax data in a common format for all OECD countries from 1965 onwards. This year’s edition includes a special feature on tax revenue buoyancy in OECD countries.

The Global Forum on Transparency and Exchange of Information for Tax Purposes (Global Forum) is a multilateral framework for tax transparency and information sharing, within which over 160 jurisdictions participate on an equal footing. The Global Forum monitors and peer reviews the implementation of the international standards of Exchange of Information on Request (EOIR) and Automatic Exchange of Information (AEOI). AEOI provides for the automatic exchange of a predefined set of financial account information between tax authorities on an annual basis to assist them in ensuring the correct amount of tax is paid. To ensure the AEOI standard is fully effective, the Global Forum carries out a review of each jurisdiction’s domestic and international legal frameworks to ensure they are complete, as well as a review of the effectiveness of their implementation of the standard in practice. This report presents the latest conclusions of the peer reviews of the legal frameworks put in place by jurisdictions to implement the AEOI standard. It supplements the assessments of the legal frameworks and the initial reviews of the effectiveness of their implementation in practice published in 2022, for around 100 jurisdictions that were the first to commit to commence AEOI. This report also contains the results of the Global Forum’s initial peer reviews in relation to the effectiveness in practice of the implementation of the standard by jurisdictions commencing exchanges in 2019.

Successfully transitioning to net-zero greenhouse gas (GHG) emissions requires effective mitigation policy packages, which include carbon pricing measures: a cost-effective policy instrument that not only reduces emissions but also generates revenue to support the transition. This fourth edition of Effective Carbon Rates provides an overview of the carbon pricing landscape, examining fuel excise taxes, carbon taxes, and emissions trading systems (ETSs) through 2021, with updates on developments until 2023. The policy mechanisms examined directly impact the cost of emitting GHGs, influencing shifts in production, consumption, and investment towards low- or zero-carbon options. The analysis covers 72 countries which together account for approximately 80% of global GHG emissions. The report focuses on developments in ETSs and transport fuel taxes amidst the energy crisis and provides comprehensive and comparable data on the current status of GHG emissions pricing that can assist policymakers in identifying priorities and refining carbon mitigation strategies.
