For multinational corporations, tax professionals, and policymakers, understanding these changes is paramount. This post breaks down the key updates, explores their implications, and offers actionable recommendations for navigating this new era of international tax policy.

Key updates in the 2025 OECD model tax convention

The 2025 update introduces several pivotal changes designed to modernise international tax rules. The core amendments address four main areas: the rise of remote work, the taxation of natural resources, dispute resolution, and transfer pricing.

1. Taxation of cross-border remote work

The global shift towards remote work arrangements has created significant uncertainty regarding tax obligations. The new guidance provides much-needed clarity on when a home office or other remote workspace constitutes a "permanent establishment" (PE) for a business, thereby creating a taxable presence in another country.

• The 50 per cent threshold as safe harbour: A central feature is a new benchmark specifying that, in general, a home office will not be considered a place of business for an enterprise if the employee works from there for less than 50 per cent of their total working time in a 12-month period. This introduces a practical safe harbour for businesses monitoring remote work arrangements. If this threshold is exceeded, whether the enterprise has a place of business at such location will be determined by the facts and circumstances, including consideration of whether there is a commercial reason for the activities.
• Commercial reason test: The update introduces the concept of a "commercial reason" for an individual’s presence in a specific country. If an employee’s location facilitates key business activities, such as direct client engagement, management of local suppliers, or access to business-critical resources, this increases the likelihood of a taxable presence. In contrast, remote work solely for employee convenience, cost-saving, or retention generally does not create a PE.
• Clarity for employers and employees: This framework enables organisations and staff to better manage tax risk and minimise the possibility of unexpected tax liabilities or double taxation.

2. A new framework for natural resource taxation

For decades, allocating taxing rights over income from natural resources like oil, gas, and minerals has been a complex issue, particularly for developing nations. The 2025 update introduces a new alternative provision that strengthens the taxing rights of the country where the resources are located (the source country).

• Reinforcing source-country rights: The new provision ensures that income from activities carried on in connection with the extraction and exploitation of extractable natural resources is taxed where those activities occur. This measure is especially significant for resource-endowed developing economies, helping them secure a fairer share of revenue from their finite resources.
• Lower “Permanent Establishment” threshold: The alternative provision establishes a lower threshold for creating a PE for extractive industries. Non-resident enterprises will be deemed to have a taxable presence after operating in a country for a bilaterally agreed period, which is often shorter than the standard PE threshold.
• Gains from asset disposal: The update also clarifies rules for taxing gains from the sale of assets related to extractive activities, including shares in companies whose value is derived from natural resources.

3. Enhancing dispute resolution and tax certainty

Tax disputes between countries can be lengthy and costly. The 2025 update strengthens the Mutual Agreement Procedure (MAP) under Article 25 to improve the efficiency and effectiveness of dispute resolution.

4. Refining transfer pricing and financial transactions

Transfer pricing remains a major focus for tax authorities. The updates to Article 9 provide clearer guidance on financial transactions.

• Interest deductibility: The commentary clarifies how domestic interest deduction limitation rules, such as those recommended under the BEPS Action 4 report, interact with tax treaty provisions. This helps prevent companies from using excessive interest payments to erode their taxable base.
• Debt vs. equity: The update addresses the re-characterisation of debt as equity, giving tax administrations a stronger basis for challenging financing arrangements that are not commercially sound. This ensures that the allocation of profits reflects the true economic substance of the transactions.

5. Exchange of Information

The 2025 update includes important changes regarding the exchange of information between tax authorities.

• Use of exchanged information: Information received through an exchange can be used for tax matters concerning persons other than those in respect of which the information was initially received.
• Taxpayer access and disclosure: The update reflects agreed interpretative guidance on taxpayer access to exchanged information and the disclosure of reflective non-taxpayer specific information about or generated on the basis of exchanged information. Such reflective information may be disclosed to third parties if it does not reveal taxpayer's identity

Implications for stakeholders

These updates carry significant implications for governments, multinational enterprises, and developing countries.

For governments:
The new rules offer enhanced tools to protect their tax base and ensure fair taxation of cross-border activities. The guidance on remote work provides a modern framework, while the provisions on natural resources empower source countries to claim a greater share of revenue.

For businesses:
While the updates provide welcome clarity, they also introduce new compliance challenges. Companies must review their remote work policies, transfer pricing strategies, and operations in the extractive sector to align with the new standards. Proactive planning will be essential to manage tax risks and avoid disputes.

For developing economies:
The focus on source taxation for natural resources is a major victory. By adopting these new provisions in their tax treaties, developing nations can significantly bolster their revenue streams from the extractive industries, providing vital funds for public services and infrastructure.

Recommendations for a smooth transition

To effectively adapt to the 2025 OECD Model Tax Convention update, consider the following OECD-supported actions:

• Review and update cross-border employment policies: Businesses should carefully assess existing remote work arrangements and cross-border employment contracts to ensure alignment with the new permanent establishment thresholds and the "commercial reason" test introduced by the OECD.
• Analyse extractive industry operations: For companies involved in the extraction of natural resources, it is essential to evaluate projects and service agreements under the revised, lower permanent establishment thresholds, ensuring activities are structured in compliance with the updated guidance. Companies should note that the provision covers both offshore and onshore activities
• Incorporate updates into bilateral tax treaties: Governments are encouraged by the OECD to adopt the revised Model Tax Convention provisions in their bilateral tax treaties, enhancing consistency and legal certainty in cross-border tax matters.
