Home Office Permanent Establishment from 2026: Austria’s Ministry of Finance endorses the OECD update – what foreign businesses should do now
Remote work has become standard—but from a tax perspective, it can unexpectedly create a Permanent Establishment (PE) in another country. On 4 January 2026, Austria’s Ministry of Finance (BMF) issued an information paper summarising the OECD Model Commentary update (November 2025) on when working from a home office (or other private locations) may create a PE under Article 5 concepts.
For foreign entrepreneurs expanding into Austria, this matters immediately: if an employee (or key person) works remotely from Austria, the arrangement may trigger corporate income tax exposure on profits attributable to an Austrian PE, plus compliance and documentation duties. This is exactly where Heinz Kobleder – Tax Advisors supports international clients as a trusted Tax Adviser in Austria—turning complex treaty rules into workable operating models.
1. The concept: when a private place becomes a “fixed place of business”
A PE typically requires a fixed place of business with a sufficient degree of permanence, through which the company’s business is carried on. The BMF emphasises that the OECD’s new guidance applies not only to a classic home office, but also to other private places such as a second home or holiday accommodation.
Importantly, even if a place is “fixed”, treaty exceptions may still apply (for example, where activities are purely preparatory or auxiliary). In practice, the key is the actual function performed and whether it forms part of the enterprise’s core business.
2. The 2026 framework: two conditions that must be met together
Austria’s BMF highlights two criteria and makes clear they must be considered together:
2.1 Working-time indicator (the 50% benchmark)
A home office may generally constitute a PE where the individual spends at least 50% of their working time over a twelve-month period working from that home office.
Why this is tricky: tracking sounds simple, but definitions matter. How do you treat client visits, travel days, hybrid days, or “work from anywhere” periods? Businesses need a consistent method that stands up in practice.
2.2 Commercial reason test (economic reasons of the enterprise)
Even if the 50% benchmark is met, the BMF summarises that one must assess whether there is a commercial/economic reason for the enterprise to have the individual working from that state—typically where the person’s physical presence facilitates the enterprise’s business, for instance because relevant customers, suppliers, resources, or stakeholders are located there. Sporadic contact should not be sufficient, and enabling home office merely to retain the person is not meant to be enough on its own.
Rule of thumb: 50% working time + commercial reason = increased PE risk. If one element is missing, risk generally decreases, but an individual assessment remains essential.
3. PE risk patterns for foreign businesses operating in Austria
Common real-world scenarios include:
- Sales or account roles based in Austria, working mainly from home while serving Austrian customers.
- Service/project roles where being located in Austria materially helps delivery (customer proximity, local resources).
- Key-person structures where one individual carries the core business. The OECD commentary flags that different considerations may apply where the home-working person is the only or most important person performing the enterprise’s business.
For many SMEs, “one key person” is exactly the model: a country lead, business developer, or senior specialist can create real substance in Austria even if contracts are signed elsewhere.
4. When does this apply? Transition from 2025 to 2026
The BMF states that the OECD’s clarifications should generally be used to interpret Austrian tax treaties that align with Article 5 concepts. At the same time, the BMF notes that the prior administrative practice may still be applied until the end of 2025, while from 2026 the updated guidance is decisive.
For businesses with cross-border remote work already in place, 2026 should be treated as a trigger to refresh contracts, policies, tracking, and documentation—before a PE risk materialises unintentionally.
5. Practical steps to manage PE exposure
As your Tax Adviser in Austria, Heinz Kobleder – Tax Advisors typically recommends a structured approach:
- Review the policy and contractual set-up
- Is home office employee-driven, or enterprise-driven?
- Is there a realistic alternative workplace (office/coworking)?
- Implement PE-relevant working-time tracking
- Track time by country (tax-relevant, not only HR-relevant).
- Define what counts as “home office time” consistently.
- Document the commercial reason (or the absence of one)
- Why is it necessary or beneficial for the company that the person is in Austria?
- Be careful: customer-proximity arguments can help commercially, but can increase PE risk if not structured properly.
- Analyse functions and decision-making
- Who negotiates or concludes contracts?
- Where are key risks managed, and where is value created?
- Prepare a “managed PE” option
If a PE is likely, it may be more efficient to structure it correctly than to fight the facts later: profit attribution/transfer pricing, registrations, ongoing compliance, and a clear documentation file.
6. Conclusion: remote work needs tax design, not just HR and IT
The OECD update—endorsed by Austria’s BMF—puts measurable intensity (the 50% benchmark) and commercial reasons at the centre of the PE analysis. Foreign businesses with people working from Austria should treat 2026 as a natural point for a PE review, so that flexible work does not inadvertently become a tax and compliance burden.
