This article examines the challenges of international double taxation on cross-border services, particularly the complexities in tax treaty allocation rules that create uncertainty and opportunities for tax arbitrage. Business services, often managed through transfer pricing or dedicated service clauses, exemplify these issues. While transfer pricing can yield precise results without expanding tax treaty clauses, it requires substantial resources that may burden developing countries disproportionately. This raises a policy dilemma on whether the solution lies in refining norms, improving enforcement, or both. The article also questions whether developing countries should bear the cost of aligning with global transfer pricing standards or if developed nations should contribute more to capacity-building efforts.

This article explores significant inconsistencies in treaty law that have weakened the international tax regime, drawing on perspectives from public international law and survey data from treaty negotiators. It suggests that effective reform should incorporate greater formality, enhanced multilateral components, and the establishment of an independent tax forum to strengthen the regime.

This article examines the international tax challenges associated with private equity funds (PEFs), which are increasingly significant players in global mergers and acquisitions and capital markets. PEFs often avoid entity-level taxation through pass-through structures, enabling investors to reduce tax liabilities, particularly through low capital gains rates on carried interest. The article critically assesses whether PEF investments should be classified as active or passive, which could shift the primary taxing jurisdiction for cross-border income, including carried interest. It further explores tax neutrality issues, noting that while PEFs achieve tax neutrality domestically, international investments may result in over- or under-taxation due to the lack of multilateral pass-through rules. The article ultimately discusses strategies to improve tax neutrality in cross-border PEF investments.

This article assesses the potential tax burden across OECD countries from 2000 to 2021 using both Data Envelopment Analysis (DEA) and Stochastic Frontier Analysis (SFA) to evaluate tax capacity. The study identifies countries close to their potential tax capacity versus those further from it, determining whether they might sustain a higher or lower tax burden relative to comparable nations. Results indicate that countries like Belgium, Colombia, Finland, France, Italy, Latvia, the Slovak Republic, and Sweden consistently operate efficiently near their tax capacity frontier.

This article addresses the existential challenges facing the international tax regime (ITR) in the 21st century, focusing on the "trilemma" of balancing liberal democracy, national self-determination, and economic globalization. To tackle these conflicting forces, the article proposes a new global tax governance model that meets the UN's 2023 framework guidelines for international tax cooperation and aligns with the OECD/G20 BEPS Project.

The model is structured as two concentric circles representing an ecosystem with both top-down and bottom-up governance. The top-down aspect resembles a bicameral legislative structure, creating standardization agreements under UN oversight, while the bottom-up element adopts a pledge-and-review approach inspired by the Paris Agreement. This dual framework aims to integrate global tax governance through repeated cooperation, balancing consensus with voting, and ensuring fair stakeholder representation across the global North and South. The theoretical foundation draws on a two-sided platform perspective from antitrust and international law.

This proposed ninth directive on administrative cooperation in taxation would establish a framework for exchanging pillar 2 information from multinational entities among EU member states and with non-EU jurisdictions by transposing the OECD standard global anti-base-erosion information return into EU law.

This report sets out recent developments in international tax reform since July 2024, including on the Two-Pillar Solution to Address the Tax Challenges Arising from the Digitalisation of the Economy. It also covers progress made on the implementation of the BEPS minimum standards and tax transparency, as well as updates on tax policy, tax and inequality and tax administration. This report was prepared by the OECD ahead of the fourth meeting of G20 Finance Ministers and Central Bank Governors held under the Brazilian G20 Presidency from 23-24 October 2024, in Washington D.C., United States.

This article analyzes how di¤erences in production technology, nancial frictions, time discount rates, and tax policies collectively determine the long-run asset positions and wealth distribution between countries. It contributes to understanding how national policies and economic factors shape global wealth patterns over time.

In this update, the authors analyze new data from the US Treasury to examine historical revenue effects of TCJA’s international corporate tax provisions. They also provide updated conventional estimates to assess the revenue impact of scheduled 2026 rate increases on foreign income of US corporations and assess several proposals that aim to further increase tax revenue.

Taxation of cross-border services has been identified as a high priority issue in the UN negotiations to establish a new global framework for tax. This paper analyses the defects of international tax rules as applied to services, and their exploitation by multinational enterprises, focusing on the impact on developing countries. It analyses the restrictions on source taxation of services in tax treaties, particularly those based on the model of the OECD, and shows that their spread has been accompanied by a widening deficit in services trade of developing countries, while the weakening of their attempts to protect their tax base through withholding taxes has resulted in increasing losses of tax revenue. The analysis suggests that a new approach is needed for taxation of services, breaking with the residence-source dichotomy, and adopting formulary apportionment. This could be based on the standards agreed in the Two Pillar Solution of the OECD/G20 project on base erosion and profit shifting and developed now through the UN.
