Commercial duty avoidance is under increased scrutiny right now. The strategies in question are often perfectly legal, but they tend to exploit loopholes in the tax code, which can erode the domestic tax base and damage public faith. For the tax professional, that means more compliance checks, a greater need for solid documentation, and a significantly increased risk of penalties if the rules aren't properly observed. The response has been a raft of initiatives from the OECD, the G20, the UN, and the EU aimed at improving the fairness of the tax system and increasing financial openness.
This is about the key changes to international tax avoidance rules as of 2025. It covers the OECD BEPS framework, the G20 and the UN's role in the policy space, the CRS, the EU Anti-Tax Avoidance Directives (ATAD), and new approaches to digital taxation.
OECD and the BEPS Action Plan Setting the Global Standard
The Base Erosion and Profit Shifting (BEPS) project (launched by the OECD in 2013 and backed by the G20) underpins the international tax reform agenda. Its objective is to close legal loopholes that enable multinationals to shift profits to low- or zero-tax jurisdictions.
Crucial BEPS conduct
- Action 1: Addresses the duty challenges of digital frugality
- Action 5: Targets dangerous duty practices, including preferential administrations
- Action 13: Introduces Country-by-Country Reporting (CbCR) for MNEs to improve transparency.
In 2021, BEPS 2.0 was introduced, structured around two pillars:
- Pillar One reallocates taxing rights to requesting authorities, focusing on largely digitalised and consumer-facing businesses.
- Pillar Two enacts a global minimum effective tax rate of 15%, applicable to MNEs with consolidated group earnings in excess of 750m.
By 2025, over 140 countries have agreed to implement these measures, an important advance in cross-border tax co-operation (OECD, 2021a).
Best practice for financial institutions and large multinationals is to align their transfer pricing programmes and reporting systems with BEPS Action 13 to avoid penalties for non-compliance. That means putting in place full transfer pricing documentation, full local and master files, and systems to support the CbCR. You need the data to support it, good internal controls, and regular reviews of your intercompany transactions.
G20 and United Nations Aligning Global Precedents
The G20 has been a very important political player in the drive for international tax reform. It has endorsed the OECD's BEPS agenda and remains committed to a digital tax agreement, as well as broader inclusive frameworks.
In contrast, the UN Tax Committee champions developing countries. Many developing countries would argue that the OECD standards are inherently residence-based.
Crucial Differences
- OECD Model Convention Favours hearthstone-grounded taxation (serving capital-exporting nations)
- UN Model Convention Prioritises source-grounded taxation (serving capital-importing nations)
The UN text on safeguarding the tax base of developing countries is a practical guide to designing anti-avoidance rules, particularly in the areas of transfer pricing, interest deductions, and convention abuse (UN, 2021).
Policymakers in the developing world may opt for a blended approach, combining the OECD and UN model provisions to balance revenue and foreign investment.
Common Reporting Standard (CRS) promotes fiscal transparency
The Common Reporting Standard (CRS) - developed by the OECD in 2014 - is the global standard for the automatic exchange of financial account information (AEOI) between tax authorities.
CRS Conditions
- Fiscal institutions must identify and report non-resident account holders.
- Periodic information includes account balances, interest, tips, and gross proceeds from the trade of financial means.
- Over 120 authorities share in CRS as of 2025
Often referred to as the 'global FATCA', the CRS assists tax authorities in identifying undeclared offshore assets (OECD, 2023).
Compliance tip: institutions should carry out robust due diligence (self-certification and document verification) to ensure that their tax residency reporting is accurate. The key steps are to review the account holder's documentation, identify the controlling person(s) of any entity, verify the submitted self-certification forms, and regularly monitor accounts for any changes in circumstances. A simple due diligence checklist might include confirming the validity of ID documents, checking tax residency information against a reliable source, looking for indicators of conflicting tax residency, updating client records, and documenting all steps and findings in accordance with the CRS.
EU ATAD I & II Harmonising Anti-Avoidance Rules
To combat aggressive tax planning within its own borders, the EU adopted two key directives.
ATAD I (2016)
- Interest Limitation Rule: Caps deductible interest at 30% of EBITDA
- General Anti-Abuse Rule (GAAR): Denies duty benefits for artificial arrangements
- Controlled Foreign Company (CFC): rules cover passive income from subsidiaries in low-taxed jurisdictions.
- Exit Taxation: Taxation on asset transfers out of the EU
ATAD II (2017)
- Addresses hybrid mismatches with non-EU countries to prevent the situation where a country may be both double-deducted and double non-taxable as a result of a legal mismatch.
ATAD has been fully incorporated into national law in all EU member states, providing a consistent basis for corporate taxation across the EU (European Commission, 2022).
Regulatory insight: Any tax planning involving hybrid instruments or entities should be considered in the light of the ATAD II rules. The key areas to look at are whether any hybrid mismatches could lead to double deduction, double non-taxation, or tax deferral. Red flags to watch for include payments that are deductible in more than one jurisdiction, income that is not taxed in any jurisdiction, hybrid entities treated differently in different jurisdictions, and complicated financial instruments with uncertain tax treatment. It's important to periodically look at these areas to ensure you're not unintentionally creating any compliance issues in respect of hybrid arrangements.
Digital Taxation: A New Frontier
Digitalisation has brought traditional tax frameworks to their knees. The digital economy has made traditional tax systems obsolete. Companies like Meta, Amazon and Alphabet can make profits in jurisdictions where they have no physical presence. To address this, several countries have introduced Digital Services Taxes (DSTs) on the profits of internet platforms, advertising, and e-commerce. This has, in turn, led to real tensions between countries and the prospect of trade disputes. Pillar One under BEPS 2.0 is designed to allocate taxing rights based on where value is created. Several such schemes are in place in various regions (OECD, 2024).
Emerging trend: expect greater emphasis on digital 'endless establishment' (PE) definitions and 'stowear'-based profit criteria models.
Toward a Transparent Global Tax Ecosystem
By 2025, the international tax regime will be much more coordinated, data-driven, and focused on accountability. The tools available to us (BEPS, CRS, ATAD, UN guidance, etc.) will have enabled a much more coherent global tax system built on transparency, fairness, and enforcement.
It's still very much a work in progress, though. Capacity gaps in the developing world, the shift in digital business models, and ongoing global political frictions continue to impede the attainment of global agreement. For tax professionals and compliance teams, this is now a regulatory imperative. Organisations should consider developing a formal adaptation strategy, including staff training on the new regulations, periodic reviews and updates of internal compliance policies, and processes to monitor regulatory developments in key jurisdictions. Further preventive steps could include implementing compliance checklists, running mock audits to identify gaps, and ensuring explicit communication across the business about emerging risks. Taking these practical steps will go a long way toward improving the team's ability to deal with the changing international tax regime and reducing exposure to compliance risk.
