Global Minimum Taxes Only Work When We Cooperate

Globalization has reshaped the way businesses operate, allowing goods, services, and cultural influences to flow seamlessly across borders. Nowhere is this more evident than in digital commerce, where multinational enterprises (MNEs) can generate profits in one jurisdiction while being taxed in another—or sometimes, barely taxed at all. However, while businesses have adapted to this borderless reality, tax systems remain largely tied to national laws and political boundaries. This disconnect has fueled tax-base erosion and profit shifting, prompting the need for a global approach to taxation. But how prepared are countries to cooperate and enforce a minimum global tax standard? 

The OECD’s Two-Pillar Initiative: A Framework for Global Taxation 

In response to growing concerns over tax avoidance by MNEs, the Organization for Economic Cooperation and Development (OECD) and G20 introduced the Two-Pillar Initiative in 2021. The goal? To combat profit shifting and base erosion through an internationally agreed-upon set of tax rules. This initiative consists of: 

• Pillar One, which seeks to ensure fair taxation of digital services by reallocating taxing rights to jurisdictions where revenues are generated. 

• Pillar Two, which establishes a global minimum tax of 15% on large multinational corporations to prevent tax competition among nations. 

  
  

While the initiative is ambitious, its success hinges on global cooperation. And that’s where the challenge begins.

A Patchwork of Implementation: Who’s On Board? 

Some countries, including Canada, Australia, and the United Kingdom, are actively working to implement the 15% minimum tax under Pillar Two. Their willingness to legislate this tax demonstrates a commitment to global tax fairness. However, other jurisdictions, such as the United States, remain hesitant, particularly when it comes to Pillar One’s digital services tax. This reluctance stems from concerns about ceding taxing rights and the potential impact on US-based tech giants. 

Even Canada, an early proponent of global taxation efforts, is growing impatient with waiting for full international cooperation on Pillar One. The concern is simple: without an agreement in place, US-based MNEs can continue to shift digital revenues out of other jurisdictions, eroding tax bases in countries that lack the power to enforce taxation on these revenues. 

The Stakes: Why Global Digital Taxation Matters 

The digital economy now represents 15% of global GDP, and its continued growth makes consistent taxation more important than ever. Without a globally enforced digital services tax, MNEs can cherry-pick favorable tax jurisdictions, minimizing what they owe and leaving countries with fewer resources to fund public services. This situation places enormous pressure on nations that want to tax digital revenues but face the risk of losing business to more tax-friendly locations. 

The Roadblock: How Do We Incentivize MNEs to Cooperate? 

One of the biggest unresolved questions is how to persuade corporations—particularly those based in the US—to willingly accept higher taxation. Without legal enforcement mechanisms, political agreements risk being ineffective. Some argue that economic penalties or trade barriers may be necessary. For example, China’s ban on Meta’s platforms offers an extreme example of how countries can exert control over digital services. While such an approach may be controversial, it raises the question: should jurisdictions consider restricting access to digital service providers that refuse to comply with global tax regulations? 

The Future of Global Tax Cooperation 

Right now, the path forward remains uncertain. The world is increasingly dependent on digital commerce, yet tax policies lag behind, creating gaps that multinational corporations continue to exploit. If countries fail to reach a consensus on a global minimum tax—particularly for digital services—many will struggle to maintain their tax bases while MNEs continue to benefit from an uneven playing field. 

To ensure fair taxation in the digital age, countries must move beyond political rhetoric and enact enforceable global tax policies. Until then, the future of global taxation remains a work in progress—one that can only succeed through true international cooperation.
