A New Era of Global Compliance

In an increasingly globalised world, corporate tax reform has become a central issue for governments, businesses, and regulators. The ability of multinational corporations to shift profits to low-tax jurisdictions has prompted concerns about base erosion, declining public revenues, and unfair competitive advantages. As a response, global frameworks such as BEPS (Base Erosion and Profit Shifting) and the global minimum tax are reshaping the international tax landscape.

At Savings UK Ltd, we recognise that evolving OECD tax rules, tighter transfer pricing standards, and complex tax treaties require a proactive approach to compliance and strategy. In this article, we explore the key drivers of reform, the risks of profit shifting, the significance of BEPS, and how businesses can navigate this era of enhanced multinational compliance.

Understanding Base Erosion and Profit Shifting (BEPS)

Base erosion and profit shifting refers to tax avoidance strategies that exploit gaps and mismatches in international tax rules. Through these strategies, multinational enterprises (MNEs) artificially shift profits to tax havens or low-tax jurisdictions, eroding the tax base of higher-tax countries.

Common BEPS techniques include:

• Manipulating transfer pricing to move profits between related entities

• Exploiting hybrid mismatch arrangements

• Treaty shopping to gain access to favourable tax treaties

• Locating intellectual property in low-tax jurisdictions

• Thin capitalisation and excessive interest deductions

These practices, while often legal under existing national laws, undermine the fairness and sustainability of the global tax system. According to the OECD, countries lose an estimated $100–240 billion annually due to BEPS—equivalent to 4–10% of global corporate income tax revenues.

The OECD BEPS Framework: A Global Response

To tackle this challenge, the Organisation for Economic Co-operation and Development (OECD), together with the G20, launched the BEPS Project in 2013. This initiative led to a set of 15 action plans, known as the OECD BEPS framework, aimed at closing loopholes in international tax rules.

Key components include:

• Action 13: Country-by-Country Reporting (CbCR) – Requires large MNEs to report revenues, profits, employees, and taxes paid in each jurisdiction.

• Action 7: Preventing the artificial avoidance of Permanent Establishment (PE) status

• Action 8–10: Aligning transfer pricing outcomes with value creation

• Action 6: Preventing treaty abuse

• Action 5: Countering harmful tax practices, especially related to intellectual property regimes

These measures, adopted by over 135 jurisdictions in the Inclusive Framework on BEPS, are transforming how companies structure their cross-border operations and report income.

At Savings UK Ltd, we assist clients in implementing BEPS-compliant structures and ensuring transparency with tax authorities through improved reporting.

The Global Minimum Tax: Ending the Race to the Bottom

Perhaps the most ambitious component of corporate tax reform is the introduction of the global minimum tax, led by the OECD under Pillar Two of its Inclusive Framework.

In 2021, over 140 countries agreed to a global minimum corporate tax rate of 15% for large multinationals (typically those with revenues over €750 million). The goal is to reduce incentives for profit shifting and ensure that corporations pay a fair share of tax regardless of where they operate.

Key Mechanisms:

• Income Inclusion Rule (IIR): Parent entities are taxed on low-taxed income of foreign subsidiaries.

• Undertaxed Payments Rule (UTPR): Denies tax deductions for payments made to related entities in low-tax jurisdictions.

• Subject to Tax Rule (STTR): Allows source countries to impose tax on certain intra-group payments if they are subject to low or no tax.

This new regime represents a paradigm shift, challenging traditional tax haven models and compelling multinationals to reassess how they allocate profits and where they base their operations.

Transfer Pricing: Aligning Value with Taxation

Transfer pricing—the pricing of transactions between related parties within an MNE—is central to the debate over base erosion. When pricing is not set at arm’s length, profits can be artificially shifted across borders.

The OECD has tightened its transfer pricing guidance under BEPS, requiring companies to:

• Demonstrate how value is created in different parts of the business

• Document transfer pricing policies in Local and Master Files

• Provide Country-by-Country Reports (CbCR) to tax authorities

For example, a tech company may house its intellectual property in a tax haven and charge high royalties to subsidiaries in high-tax countries. Under BEPS, tax authorities now have tools to challenge such arrangements if they lack economic substance.

Savings UK Ltd works with clients to ensure their transfer pricing strategies are aligned with the OECD’s arm’s-length principle, mitigating audit risks and penalties.

The Role of Tax Treaties

Tax treaties are bilateral agreements between countries designed to prevent double taxation and promote cross-border investment. However, they have also been exploited through treaty shopping, where companies route income through jurisdictions offering the most favourable terms.

The OECD’s Multilateral Instrument (MLI) allows countries to swiftly amend existing tax treaties to implement BEPS measures. The MLI introduces:

• Principal Purpose Test (PPT) to prevent abuse of treaty benefits

• Enhanced dispute resolution mechanisms

• Provisions to address hybrid mismatches and permanent establishment status

These changes mean that companies must now review their treaty networks not just for benefits, but also for compliance obligations and risk exposure.

Corporate Tax Reform at the National Level

While global coordination is essential, corporate tax reform also requires domestic legislation. Countries are updating their tax laws to comply with BEPS, implement the global minimum tax, and safeguard their own tax base.

Examples of National Reforms:

• UK: Introduced a Digital Services Tax and adopted BEPS recommendations into transfer pricing law.

• USA: Passed the Tax Cuts and Jobs Act (TCJA), including Global Intangible Low-Taxed Income (GILTI) and Base Erosion Anti-Abuse Tax (BEAT).

• EU: Launched the Anti-Tax Avoidance Directive (ATAD), with measures against hybrid mismatches, exit taxation, and CFC rules.

These reforms aim to close loopholes while promoting investment, innovation, and economic fairness. However, they also create a more complex and dynamic compliance environment.

Challenges and Compliance for Multinationals

As tax authorities gain more data and tools, enforcement is intensifying. Multinationals face growing expectations to provide transparent, consistent, and defensible tax positions.

Key compliance challenges include:

• Navigating multiple reporting requirements (CbCR, Master File, Local File)

• Reconciling financial and tax data across jurisdictions

• Managing intercompany agreements and documentation

• Evaluating the impact of the global minimum tax

• Responding to audits, disputes, and tax authority queries

Failure to comply can result in hefty penalties, reputational damage, and even criminal investigations. That’s why at Savings UK Ltd, we help clients establish robust governance frameworks and risk controls around their international tax operations.

The Road Ahead: A More Transparent and Equitable Tax System?

While much progress has been made, corporate tax reform remains a work in progress. Key questions continue to arise:

• Will the global minimum tax be uniformly enforced?

• Can developing countries access a fairer share of tax revenues?

• How will digital taxation evolve with the rise of AI and e-commerce?

Despite these uncertainties, the direction is clear: the age of tax opacity and aggressive base erosion is ending. The future lies in multinational compliance, transparent reporting, and tax policies that reflect where real economic activity occurs.

Conclusion: Aligning Strategy with Global Tax Standards

As international efforts to combat base erosion and profit shifting accelerate, businesses must rethink how they manage their global tax footprint. The era of easy tax arbitrage is giving way to a more regulated, transparent, and accountable system.
