Strategic Myths in the Era of Global Minimum Tax: Re-examining the OECD Two-Pillar Framework and the Competitiveness of Multinational Enterprises

Strategic Myths in the Era of Global Minimum Tax: Revisiting the OECD Two-Pillar Plan and Multinational Enterprise Competitiveness

Currently, global tax governance is at a tense historical juncture. The "two-pillar" international tax reform plan promoted by the Organisation for Economic Co-operation and Development (OECD) attempts to redefine the rules for allocating multinational enterprises' profits and set a global minimum effective tax rate. On the surface, this aims to curb "race to the bottom" competition and profit shifting, but a deeper look at its policy logic and empirical basis reveals that this grand agenda may be built on a set of exaggerated anxieties, and may even undermine the long-term competitiveness of multinational enterprises and the dynamic efficiency of the global economy.

Tax Competition: From the "Race to the Bottom" Myth to Development Driver

For a long time, the issue of multinational corporate tax burdens has often triggered concerns about a "race to the bottom"—that is, countries lowering tax rates to attract investment, leading to a loss of public revenue. However, as policy researchers have pointed out, this concern overlooks a key fact: tax competition has lowered nominal tax rates but has not led to a systematic decline in tax revenue. On the contrary, in the process of globalization, increased capital mobility has made countries more cautious when setting tax rates, and effective tax competition has prompted governments to optimize public expenditure structures and reduce corporate compliance costs, thereby improving overall economic efficiency.

For multinational corporations, tax rate differences are a legitimate strategic consideration in global layout, not merely "tax avoidance" behavior. Through location choices, firms reflect the quality of public services and regulatory environments across different jurisdictions, which is a normal part of market competition. Stigmatizing this process amounts to ignoring a key driver of corporate globalization.

Corporate Income Tax: An Institutional Legacy of the 20th Century

From a governance perspective, the modern corporate income tax was born in an era when national economic boundaries were clear and capital mobility was low. In the intangible economy of the 21st century, corporate value chains are highly dispersed, and digital services can be provided across borders instantly. Traditional tax systems based on physical presence and the arm's length principle are increasingly outdated. The complexity of corporate income tax—including transfer pricing rules, attribution, and residency determination—is itself a massive source of compliance costs and uncertainty.

Regarding corporate income tax as a "remnant of the 20th century" is not a radical statement, but a sober judgment on the direction of institutional evolution. In an era when intangible capital and ultra-large-scale platforms are at the core of value creation, profit-based tax bases can easily be reconfigured. This leads to a paradox: the more complex the tax system, the greater the incentive for firms to engage in tax planning, and the harder it is for tax authorities to respond.

The Two-Pillar Plan: An International "Tax Cartel" or Legitimate Governance?The essence of the OECD's two-pillar solution is an attempt to redistribute taxing rights over large multinational enterprises through coordinated action in the absence of a global fiscal authority. Pillar One aims to grant market countries taxing rights over a portion of profits, particularly targeting highly profitable digital enterprises; Pillar Two compresses the space for tax rate competition through a global minimum tax rate (15%). On the surface, this helps reduce base erosion, but its actual policy effects may vary by firm.

The design of Pillar One is highly focused on the most successful American multinationals, which has sparked intense controversy at the geoeconomic level. Indeed, many observers believe that the two-pillar solution is more a collective action by governments seeking new revenue sources in times of fiscal deficits than a rigorous tax system optimization. The global minimum tax rule will directly diminish the attractiveness of low-tax countries as investment destinations, potentially altering regional supply chain configurations, and also expose small and medium-sized open economies to greater capital outflow pressure.

For corporate strategy managers, such an uncertain tax environment in itself constitutes a risk. Multinationals need to reassess their holding structures, intellectual property arrangements, and profit repatriation strategies, while coping with overlapping compliance obligations across multiple jurisdictions.

Profit Shifting: Overstated Anxiety

Empirical research on profit shifting is far more complex than public discussion suggests. Several analyses point out that the profits booked by multinationals in low-tax jurisdictions are systematically overstated in statistics, while the actual economic scale of profit shifted out of high-tax countries is relatively small and has been shrinking in recent years. This implies that the core narrative of the OECD reform—"huge profits trapped in tax havens"—lacks a solid factual foundation.

If this narrative is exaggerated, then the global minimum tax designed on that basis may lead to untargeted over-regulation. For many businesses, tax compliance costs rise and the risk of double taxation increases, while the actual public interest gains may be limited.

Toward a Simpler International Tax Order

Faced with the institutional complexity brought by the two-pillar solution, some analysts advocating "bold reform" argue that the very foundation of international taxation should be thoroughly reconsidered. One direction is to shift back toward consumption-based taxation, for example using a destination-based cash-flow tax at its core to replace profit-based corporate tax. Such a system would avoid taxing normal returns on investment, thereby reducing distortions to investment decisions, while naturally adapting to global value chains.

Another idea is to simplify attribution rules, or even replace transfer pricing under the arm's length principle with formula-based allocation, thereby eliminating the costly "documentation game." Whatever the specific design, these reforms all point to the same principle: tax systems should remain as neutral, transparent, and predictable as possible, serving long-term investment and economic growth rather than merely short-term fiscal needs.For multinational corporations, this means that tax strategy must be elevated from a "compliance function" to a "governance issue." Changes in the tax system are not merely changes in financial parameters, but also a test of how enterprises restructure their global strategies, organizational structures, and stakeholder relationships. Those companies that can adjust flexibly and clearly understand the political and economic logic behind tax policies will gain competitive advantages amid uncertainty.

Conclusion

The controversy triggered by the OECD global tax reform goes far beyond the level of tax rates. It concerns how the contract between enterprises and states can be rebuilt in an era of deeply evolving globalization. Beneath the rhetoric of a "race to the bottom," what truly needs to be discussed is how to design a set of rules that can ensure the sustainability of public finances without excessively sacrificing economic vitality and cross-border investment freedom. The global minimum tax may be a policy shock, but the real remedy may lie in institutional innovation that is simpler, more long-term-oriented, and more respectful of market mechanisms.

For business leaders, the lesson of this issue is that taxation is no longer just a technical matter, but an organic component of an enterprise's long-term competitiveness strategy. In a global environment of low growth and high uncertainty, understanding and anticipating tax governance is becoming an indispensable part of the core capabilities of multinational corporations.
