From BEPS to Pillar Two: How Anti-Avoidance Rules Are Reshaping Corporate Tax Planning

1. A New Era for Corporate Tax Strategy

Over the past decade, the global tax landscape has shifted from rate competition to rule tightening. The OECD/G20 Base Erosion and Profit Shifting (BEPS) project has rolled out a comprehensive set of anti-avoidance measures, and now Pillar Two’s global minimum tax is adding another powerful layer of protection for tax bases worldwide.

For multinational groups operating in or from the Caribbean and Latin America & the Caribbean (LAC), this is not just a technical change. It fundamentally alters where value can be booked, how structures must be designed, and what “tax efficient” really means.

The OECD’s Corporate Tax Statistics 2025 report shows just how far jurisdictions have gone in implementing BEPS-consistent rules:

• 45 jurisdictions have adopted rules neutralising hybrid mismatch arrangements under Action 2.

• 56 jurisdictions now have Controlled Foreign Company (CFC) rules in place, up from 49 in 2019, with adoption more common among high-income countries.

• 87 jurisdictions have interest limitation rules, covering 106 separate regimes, a sharp rise from 67 regimes in 2019.

• 65 IP regimes exist across 50 jurisdictions, with 46 already assessed as “not harmful” under BEPS Action 5 standards.

• 31 jurisdictions operate mandatory disclosure rules (Action 12), and 106 jurisdictions require Country-by-Country Reporting (CbCR) (Action 13).

Layered on top of this, the Pillar Two Global Anti-Base Erosion (GloBE) rules introduce a 15% global minimum tax, forcing groups to rethink the viability of low-tax structures even where domestic rules are still evolving. The same Corporate Tax Statistics report already treats certain levies (such as Zakat in some jurisdictions) as “covered tax” for GloBE purposes, highlighting how closely tax policy is now tied to the minimum tax framework.

For boards and CFOs, the message is clear: tax arbitrage space is shrinking, and tax planning must pivot from exploiting gaps to building robust, substance-rich, and data-defensible structures.

2. BEPS: Closing the Classic Profit-Shifting Channels

The BEPS Actions were designed to ensure that profits are taxed where economic activities take place and where value is created. The 2025 Corporate Tax Statistics show that many of the core BEPS measures are no longer theoretical — they are embedded in domestic law.

2.1 Hybrid mismatches (Action 2)

Hybrid mismatches exploit differences in how jurisdictions classify instruments or entities, leading to double deductions or deduction with no inclusion. Action 2 recommends rules that either deny the deduction or require inclusion of income to neutralise these mismatches.

By 2025:

• 45 jurisdictions have adopted measures to neutralise hybrid mismatches.

For corporate groups, this means:

• Funding structures using hybrid instruments are far more likely to be challenged.

• Complex cross-border financing now requires alignment of legal, accounting and tax characterisation.

2.2 CFC rules (Action 3)

CFC rules bring into the parent jurisdiction certain low-taxed profits of controlled foreign entities, targeting offshore structures that create indefinite deferral or non-taxation.

Key findings for 2025:

• 56 jurisdictions report having CFC rules, up from 49 in 2019.

• These rules are more common in high-income jurisdictions than in developing peers.

Practical impact:

• “Parking” IP, treasury, or service centre income in low-tax jurisdictions is increasingly likely to trigger pick-up in the parent jurisdiction.

• Groups must consider substantial activity tests, income categorisation (passive vs active), and exceptions when designing holding and IP structures.

2.3 Interest limitation rules (Action 4)

Excessive interest deductions are a classic profit-shifting mechanism. Action 4 links deductible interest to a measure of economic activity (often EBITDA) through fixed-ratio and group-ratio rules.

By 2025:

• 87 jurisdictions have interest limitation rules in place.

• Of 106 interest limitation rules globally, 45 are thin capitalisation rules and 29 are fixed-ratio rules.

For corporate treasury and finance:

• Highly leveraged, intra-group debt strategies are now constrained by interest-to-EBITDA caps, debt-to-equity ratios, and targeted anti-avoidance rules.

• MNEs must carefully calibrate group capital structure, not only for financial efficiency but also for tax deductibility thresholds.

2.4 IP regimes and harmful tax practices (Action 5)

Preferential IP regimes were once a powerful tool for profit shifting. Under Action 5, the nexus approach now conditions benefits on the extent to which R&D activities are conducted in the jurisdiction granting the benefit.

The 2025 statistics show:

• 65 IP regimes across 50 jurisdictions, of which 46 are assessed as “not harmful”, and 11 are already abolished.

• These non-harmful regimes provide tax reductions ranging from full exemption to about a 40% cut in the standard rate, commonly around a 50% reduction.

This reshapes planning by:

• Making substance (real R&D activity) central to IP planning.

• Requiring that any IP or patent box structure be aligned with genuine development, enhancement, maintenance, protection and exploitation (DEMPE) functions in the jurisdiction.

2.5 Transparency: MDR and CbCR (Actions 12 & 13)

The data also underline the growing transparency infrastructure:

• 31 jurisdictions have mandatory disclosure rules focussing on aggressive tax planning hallmarks.

• 106 jurisdictions require CbCR filing for fiscal year 2022.

CbCR is used for high-level risk assessment, audit selection and audit planning, rather than as direct evidence of BEPS.

For multinationals, this means that large discrepancies between profits, people and assets across jurisdictions now trigger visible risk indicators.

3. Enter Pillar Two: The Global Minimum Tax

While BEPS tightened the rules around how profits can be shifted, Pillar Two asks a more fundamental question: Is there a minimum level of tax that should apply regardless of where profits are parked?

Pillar Two introduces:

• A 15% global minimum effective tax rate on the profits of large MNEs (generally with consolidated revenues ≥ EUR 750m).

• A set of rules (GloBE) — including the Income Inclusion Rule (IIR) and the Undertaxed Profits Rule (UTPR) — designed to ensure that if one jurisdiction does not tax up to 15%, another jurisdiction will.

• The concept of “covered taxes”, which can include corporate income tax and other profit-based levies such as certain resource taxes or Zakat, provided they meet GloBE criteria. The OECD’s methodology for forward-looking effective tax rates already treats such levies as covered tax for GloBE purposes in some cases.

In practice, this means:

• The value of low-tax jurisdictions is capped: if profits are taxed below 15% locally, a top-up tax may be triggered in the jurisdiction of the ultimate parent or elsewhere in the group.

• Structuring purely for low statutory rates or preferential regimes becomes far less powerful unless combined with real economic substance and genuine activities.

4. How BEPS and Pillar Two Work Together

For tax planners, BEPS and Pillar Two are not separate projects; they operate as complementary layers:

1. BEPS Actions (2, 3, 4, 5, 12, 13)

   • Remove or restrict classic avoidance techniques (hybrids, excessive interest, IP regimes without substance, opaque planning schemes).

   • Increase visibility and risk of detection through CbCR and MDR.

2. Pillar Two

   • Ensures that, even where gaps remain or preferential regimes are still in play, the group’s global effective tax rate cannot fall below 15% (subject to GloBE design).

The combined effect is:

• A shift away from “where can we pay the lowest rate?” to

• “where does it make business sense to invest, given that we will pay at least 15% anyway, and how do we optimise within that constraint?”

5. Strategic Implications for Corporate Structures

5.1 Reduced payoff from pure tax-driven location choices

With many preferential regimes now amended, abolished or labelled non-harmful, and with Pillar Two setting a floor on effective tax rates, the incremental benefit of routing profits via zero- or low-tax jurisdictions is shrinking.

Groups must now:

• Reconsider the role of holding companies, finance companies and IP hubs.

• Re-evaluate whether complex multi-jurisdiction structures justify their compliance and governance cost.

5.2 Substance, people and data become central

Because CbCR reveals where people, assets and profits are located, tax strategies that misalign profit with real activity are more likely to draw scrutiny.

This pushes groups to:

• Align DEMPE functions with IP income.

• Ensure genuine management, decision-making, and operational functions exist in key jurisdictions.

• Invest in robust transfer pricing documentation, internal controls and data systems.

5.3 Financing and capital structure under pressure

Interest limitation rules now constrain debt-based planning, particularly where leverage exceeds recommended thresholds or where interest expense does not match real economic activity.

Treasury teams need to:

• Optimise group leverage within ILR constraints and Pillar Two effective tax modelling.

• Revisit hybrid tools, profit-participating loans, and related-party financing structures that may be neutralised under Action 2 and GloBE.

6. The Caribbean & LAC Perspective

For Caribbean and LAC jurisdictions, the Corporate Tax Statistics show that while effective tax rates and statutory rates vary widely, several jurisdictions historically relied on preferential regimes and low statutory rates to attract international business.

In a world of BEPS and Pillar Two:

• Jurisdictions must ensure their incentive regimes (e.g., IP, special economic zones, free zones) meet Action 5 standards and do not undermine the global minimum tax.

• MNEs headquartered in or investing into the region must adjust their structures so that:

  • Substance exists where profits are recognised.

  • The group’s global Pillar Two position is managed proactively to avoid unexpected top-up tax in other countries.

  • Regional investments remain attractive on a post-tax, post-Pillar-Two basis, particularly in sectors like financial services, energy, tourism, and digital services.

For regional groups eyeing international expansion, it also means:

• Early alignment with BEPS and Pillar Two expectations can reduce future disputes and reputational risk, making the group more attractive to global investors and lenders.

7. What Boards and CFOs Should Be Asking

To stay ahead, boards, audit committees, and CFOs should be asking:

1. Where does our group sit under BEPS measures?

   • Do we rely on hybrids, IP regimes, or high leverage that could be challenged?

   • How exposed are we to CFC rules in parent jurisdictions?

2. What is our expected Pillar Two effective tax rate by jurisdiction?

   • Where might we face top-up tax?

   • Are we capturing all “covered taxes” effectively?

3. Is profit aligned with people and assets as reflected in our CbCR?

   • Do our internal narratives, transfer pricing models and CbCR data tell the same story?

4. Are our governance, systems and documentation fit for purpose?

   • Do we have consistent tax risk management frameworks?

   • Are we ready to respond quickly to MDR obligations or information requests?

5. What restructuring options exist that improve resilience rather than just chasing lower rates?

   • Can we simplify the group structure while maintaining commercial and tax efficiency?

   • Should we relocate functions, intellectual property or treasury operations?
