This paper documents new facts on corporate taxation and the revenue potential of corporate minimum taxes, leveraging firm-level tax returns from 16 countries. First, effective tax rates follow a humped-shaped pattern with firm size: small firms benefit from reduced rates, while large firms take...

This paper characterizes profit shifting behavior across the size distribution of multinational enterprises (MNEs) to evaluate the targeting of the recently introduced Global Minimum Tax (GMT). Using German microeconomic administrative data with no reporting gaps for tax havens, we first...

This Perspective discusses the fiscal and economic impacts of the global minimum tax; currently being implemented by many countries around the world. The global minimum tax is expected to raise tax revenues, reduce profit-shifting, and allow jurisdictions to strike a better balance between...

Analysis of the international network of double tax treaties reveals a large potential for tax avoidance. Developing countries are, on average, not more likely to suffer from tax revenue losses than other countries. Yet, this average masks the fact that several countries, such as Bangladesh,...

We assess the welfare implications of the Global Minimum Tax (GMT) on corporate income in a multi-country macroeconomic model. The objectives of the GMT are to mitigate harmful tax competition and to curb wasteful profit shifting. The theoretical literature suggests that the welfare effects of...

This study assesses the impact of the Global Minimum Tax (GMT) on the attraction of foreign direct investment (FDI) in Vietnam. The authors rely on the analytical framework of UNCTAD (2022) and descriptive statistical methods to analyze and evaluate the impact of GMT on FDI attraction. The...

This chapter provides a description of one of the key anti-tax-avoidance rules to combat profit shifting by multinational corporations, so called Controlled Foreign Corporation (CFC) rules that directly target income in low-tax countries. We explain some key institutional features of CFC...

We develop a methodology to decompose the tax revenue impact of the global minimum tax introduced in 2024 into several components and quantify its potential impact on profit shifting. We apply it to 34 thousand multinational-country observations from tax returns, financial statements and...

The Global Minimum Tax (GMT) is applied only to firms above a certain size threshold, permitting countries to set differential tax rates for small and large firms. We analyse tax competition between a tax haven and a non-haven country for heterogeneous multinationals to evaluate the effects of...

International corporate tax system does not succeed very well in taxing the cross-border business of the multinational enterprises. Therefore, both the European Union (EU) and the Organization for Economic Cooperation and Development (OECD) have proposed several tax reforms. We recognize in this...

This paper shows that the OECD inclusive framework of Pillar Two fails to implement the claimed 15% minimum corporate tax for all subsidiaries of multinational corporations that are not shell companies. The reason is that the Substance-based Income Exclusion of Pillar Two allows to tax-deduct...

Transnational corporations (TNCs) act as unitary firms in an increasingly globalised economy, but taxes on their profits are levied by national states. Hence, international tax rules have from the start been riven by contradictory approaches: either to determine the taxable profits attributable...

This paper investigates the incentives for countries to implement and maintain the global minimum tax introduced by the G20/OECD’s Inclusive Framework 2021 agreement: Pillar 2. It argues that the agreement has sufficient elements to create incentives for large headquarters countries to...

Countries may soon adopt domestic minimum taxes in response to the global minimum tax under the Global Anti-Base Erosion (GloBE) regime. These taxes, which will have priority over the global minimum tax under GloBE, could become the primary measure of ensuring that multinational enterprises...

This paper articulates and, using newly-assembled data, explores how international taxation affects aggregate tangible cross-border investment. Spillovers from statutory tax rates abroad seem: As sizable as effects from the host's rate; larger than previous consensus values (attributed to a...

The OECD’s proposal for a global minimum tax (GMT) of 15% aims for a reversal of a decline of corporate tax rates. We study the revenue effects of the GMT by focusing on strategic tax setting effects. The direct effect from less profit shifting increases revenues in high-tax countries. A...

This paper shows that the OECD inclusive framework of Pillar Two fails to implement the claimed 15% minimum corporate tax for subsidiaries of multinational corporations. The reason is that the Substance-based Income Exclusion of Pillar Two allows to tax-deduct payroll costs and user costs of...

Schemes of residual profit allocation (RPA) tax multinationals by allocating their 'routine' profits to countries in which their activities take place and sharing their remaining 'residual' profit across countries on some formulaic basis. They have recently and rapidly come to prominence in...

The OECD’s proposal for a global minimum tax (GMT) of 15% aims for a reversal of a decades-long race to the bottom of corporate tax rates driven by competition over real investments and profit shifting to low-tax jurisdictions. We study the revenue effects of the GMT by focusing on the induced...

This paper studies how the global minimum tax shapes national tax policies and welfare in a formal model of international tax competition with heterogeneous countries. The net welfare effect is generally ambiguous from the perspective of non-havens. On the one hand, the global minimum tax raises...
