In today’s interconnected economy, tax avoidance has become one of the most pressing concerns for governments, regulators, and global institutions. While multinational companies (MNCs) are expected to pursue efficiency and maximize shareholder value, governments rely on tax revenues to fund development, infrastructure, and welfare. This natural tension has given rise to increasingly sophisticated tax planning practices and equally complex countermeasures.
Below are some key themes that often come up in discussions on international taxation, based on the industry observations.
Profit Shifting: Domestic vs. Cross-Border
A common claim is that profit shifting across borders amounts to tax avoidance, while shifting within the same country does not. This distinction, however, oversimplifies the issue.
Profit shifting, regardless of geography, can be problematic when it lacks economic substance and is purely designed to exploit loopholes. Even within a single country, companies may move profits to jurisdictions or entities with favourable tax treatments, undermining the spirit of the law. Across borders, the risks are amplified because they erode national tax bases and allow companies to arbitrage between tax systems.
The real question, therefore, should not be where profits are shifted but why and how. If the transactions align with genuine business operations and value creation, they may be justified. If not, they risk falling squarely into the realm of tax avoidance.
Thin Capitalization and Transfer Pricing: Necessary but Not Sufficient
Thin capitalization rules which limit excessive interest deductions have improved the international tax landscape. They make it harder for MNCs to strip earnings through intra-group financing structures. Yet, on their own, these rules cannot fully curb aggressive tax planning. To be effective, they need consistent application across jurisdictions, integration with broader anti-avoidance regimes, and strong enforcement.
The same holds true for transfer pricing. The arm’s length principle has been the cornerstone of international tax for decades, requiring related-party transactions to be priced as if they were between independent entities. While this provides a framework, it is not always practical. Complex corporate structures, intangibles like intellectual property, and global supply chains often make “arm’s length” more theoretical than real.
This has fuelled debates around alternative methods, from formulary apportionment (allocating profits based on sales, assets, and employees) to simplified approaches for low-risk transactions. It has also led to initiatives like the OECD’s Global Minimum Tax, which aims to create a baseline floor for taxation.
The Global Minimum Tax: Promise and Complexity
The introduction of a 15% Global Minimum Tax (GMT) under the OECD’s Pillar Two is a historic milestone. For the first time, there is an international consensus that companies should pay at least a minimum level of tax, no matter where they are headquartered or where their profits are booked.
Yet, the GMT is not without challenges. The calculation itself is highly complex, involving detailed assessments of multinational groups’ profits, taxes paid, and adjustments for carve-outs. For developing countries, which may lack administrative capacity, this complexity can be overwhelming.
Moreover, a 15% floor may not meet the fiscal needs of every country. Developing and less-developed economies often rely more heavily on corporate tax revenues and may prefer higher effective tax rates to sustain growth. Smaller companies, which are economically significant in some jurisdictions, are also largely excluded from the current scope.
Thus, while the GMT is an important step toward fairness, it is far from a comprehensive solution.
Corporate Inversions and Tax Havens: Short-Term Gains, Long-Term Risks
Another widespread practice is corporate inversion, where a company shifts its legal headquarters to a subsidiary in a low-tax jurisdiction. While the business operations remain largely unchanged, the tax benefits can be significant. Unsurprisingly, such moves are generally considered a form of tax avoidance.
Tax havens present a similar dilemma. By lowering tax rates or offering preferential regimes, countries can attract foreign investment and boost GDP figures in the short term. However, the long-term risks are substantial. Investments motivated purely by tax advantages tend to be “footloose,” generating little local employment or real development. Furthermore, reliance on tax haven behaviour undermines international cooperation and exposes countries to potential retaliation from larger economies.
Balancing Corporate Tax Rates with Economic Growth
Many countries have experimented with lowering corporate tax rates as a way to counter tax avoidance and attract investment. While this can boost business activity and employment, it comes at the cost of reduced government revenue. For nations with limited fiscal capacity, this trade-off is particularly dangerous.
The effectiveness of such policies depends on how they are structured. If lower rates are coupled with robust anti-avoidance rules, incentives for real job creation, and targeted support for domestic industries, they may yield positive outcomes. Without such safeguards, however, the long-term fiscal damage may outweigh short-term gains.
What Works Best, A Multi-Pronged Strategy?
There is no silver bullet to curb tax avoidance. A multi-pronged strategy is essential:
• Domestic enforcement must remain strong, with transparent disclosure requirements.
• International cooperation is critical, particularly between developed and developing nations.
• Simplification and harmonization of rules can reduce compliance burdens while closing loopholes.
• Technology and data analytics should be used to detect aggressive tax planning in real time.
• Finally, policies should incentivize genuine business activity, rather than rewarding artificial tax-driven structures.
The Road Ahead
As tax systems continue to evolve, the guiding principle should be substance over form. Profits should be taxed where value is truly created, not where legal entities are conveniently located. Achieving this requires more than just technical fixes; it demands collaboration, innovation, and a commitment to fairness.
Tax avoidance is not an issue that any one country can solve alone. But through coordinated global action, supported by strong domestic frameworks, we can move closer to a system where businesses contribute equitably, governments protect their tax bases, and economies thrive sustainably.
