In response to the changing work patterns and the teleworking trends that persist since the COVID-19 pandemic, the OECD has updated its commentary (the “Commentary”) of its Model Tax Convention (the “MTC”) for Article 5: Permanent Establishment. The revised guidance clarifies when an employee’s home (or another personal workspace abroad) can be treated as a “place of business” of the enterprise and therefore create a PE.
To clarify, the update does not change the treaty wording of Article 5. Specifically, it clarifies how the existing “fixed place of business” test should be applied to modern remote-working patterns, including home offices.
The revised Commentary introduces clearer guardrails, most notably a 50% working-time reference point and a business-purpose (“commercial reason”) test, to distinguish low-risk, incidental remote work from arrangements that may amount to a PE.
The key changes to remote working, at a glance, are as follows:
Amendment | Explanation |
Home office at the disposal of the enterprise |
The 2025 update removes the older, narrower home-office text (former paragraphs 18–19) and replaces it with a dedicated section (paras 44.1–44.21) on cross-border working from a home or other relevant place (e.g., second home, holiday rental, friend/relative’s home).
The section is aimed at remote work performed from a private place in the other State that is not the enterprise’s premises and not a customer/supplier/associated enterprise premises. |
New conditions and clarifications on the analysis required |
The new section clarifies how to apply Article 5(1) to remote work:
|
New clarifications on what may constitute a ‘commercial reason’ |
The Commentary indicates that a business nexus may exist where the individual’s physical presence in the State facilitates the enterprise’s business in a meaningful way. Indicators include situations where:
These indicators apply regardless of whether the interaction is with independent third parties or associated enterprises. |
New clarifications on what does not constitute a ‘commercial reason’ |
A central clarification is what does not meet the “business nexus” condition:
|
Removal of Ambiguity |
The 2025 update also deleted outdated examples and wording that caused confusion. Previously, the commentary focused on whether the employer had “required” an employee to work from home (explicitly or implicitly) as a key test for a home office PE. This was subjective and led to uncertainty. The new guidance drops the “employer requirement” criterion. |
Final Remarks
The 2025 changes to the Commentary on Article 5 provide welcome clarity on how cross-border remote work should be analysed. By introducing clearer reference points and refining the concept of business nexus, the OECD has reduced uncertainty while reinforcing that outcomes remain highly fact-specific.
