Cross-border remote work has created a recurring tax question for many international companies:
Can an employee’s home office in another country create a permanent establishment (PE) for the foreign employer, with corporate tax exposure and ongoing compliance obligations (often described as “micro-PE” risk)?
In his Bloomberg Tax piece, Christos Theophilou (STI Taxand, Cyprus) explains that tax authorities have become more willing to test these fact patterns and that the OECD’s 2025 update to the Commentary on Article 5 is an attempt to bring structure and predictability to an area that was previously driven by abstract concepts.
What Christos says is the main shift
Christos’ key message is that the OECD has moved the analysis away from a highly subjective debate about whether the employer had the home “at its disposal,” and toward a more operational framework built around
(i) permanence/continuity,
(ii) measurable working-time allocation, and
(iii) the business rationale for the employee being in that country.
The updated commentary introduces a dedicated section for “cross-border working from a home or other relevant place” (not only homes but also locations like temporary rentals), recognising these settings are different from normal business premises because access is limited and control often sits with the individual.
The three Tests he highlights: permanence, the 50% threshold, and “commercial reason”
Christos explains that the home must first have enough permanence and continuity to be “fixed”; short or incidental periods generally won’t qualify.
The headline development is the OECD’s 50% working-time threshold over any 12-month period: where the individual works from that location for less than 50% of their total time for the enterprise, the location will generally not be treated as a place of business of the enterprise. If the 50% line is met or exceeded, PE does not arise automatically; the focus then turns to whether there is a commercial reason for the enterprise to have the individual physically present in that country, meaning the person’s presence there genuinely facilitates the enterprise’s business and is not merely incidental.
What makes PE more likely (and what makes it less likely)
In Christos’ breakdown, he mentions
PE risk is more likely where the employee’s physical presence in the host country is linked to real business outcomes, for example:
- ongoing meetings/engagement with local clients
- building or developing a customer base in that market
- identifying/managing suppliers or supplier relationships
- needing access to local resources, people, or expertise that supports the business
- delivering services that require on-site presence (not purely virtual delivery)
PE risk is less likely where the arrangement is mainly:
- the employee’s personal choice (or to retain the employee), rather than business necessity
- driven mainly by cost-saving (e.g., reducing office space costs)
- supported by only occasional/intermittent local interaction that is not central to the role
Preparatory/auxiliary activities still matter: if the home-office work is mainly support functions (rather than core business operations), PE risk is reduced even if other factors exist.
Higher-risk scenario: where a “single-person business” pattern exists, i.e., one individual effectively carries out most of the enterprise’s business from a home office in the host country for an extended period.
What this means for multinationals in practice
Christos’ practical takeaway is that groups should treat cross-border remote work as a governance issue, not a theory discussion. That means monitoring actual working patterns against the 50% threshold, documenting the real business rationale (or lack of it) for the employee’s location, and mapping the activities performed to determine whether they are core business functions or preparatory/auxiliary support.
The goal is to manage risk early, before a pattern hardens into an exposure that is costly to unwind.
