Quick Summary — What This Article Covers
When a company operates across borders, one question matters more than most: have you created a taxable presence in another country without realizing it?
This isn’t about VAT or payroll taxes. It’s about whether your business has crossed the threshold of being considered “established” abroad for corporate tax purposes. That threshold is known as permanent establishment (PE).
Get it wrong, and the consequences are real. You could face back taxes, penalties, and compliance obligations in a country you didn’t plan to operate in. Overcorrect, and you end up adding unnecessary entities, legal overhead, and operational complexity.
PE is no longer just a concern for large multinationals. A remote employee, a local sales agent, or ongoing work in another country can be enough to trigger it. The rise of distributed teams since 2020 has made this far more common.
The rules are evolving too. In November 2025, the OECD updated its guidance on permanent establishment, with direct implications for companies hiring and operating internationally.
This guide breaks down what PE actually means, how it’s triggered, and how to manage the risk without slowing down your global growth.
What Is Permanent Establishment?
A permanent establishment (PE) is the point at which a foreign business becomes taxable in another country. Once that threshold is crossed, the host country gains the right to tax the profits linked to your activities there. If you stay below it, taxation generally remains limited to your home jurisdiction.
Permanent Establishment (PE)
A permanent establishment exists when a business has enough presence in a foreign country, such as a fixed place of business, employees, or agents, for that country to tax the profits generated there.
At its core, the concept comes from Article 5 of the OECD Model Tax Convention, which defines a PE as “a fixed place of business through which the business of an enterprise is wholly or partly carried on.” That definition has been around for decades, but how it’s applied has evolved significantly as companies moved beyond traditional offices, branches, and on-ground teams.
It’s important to understand that the OECD Model itself isn’t law. It’s a framework countries use when negotiating tax treaties. The actual rules that apply come from those treaties or, if no treaty exists, from local tax law. And that’s where things can vary quite a bit.
Some countries take a more aggressive view; for example, India applies a 90-day threshold for certain service-based PEs, which is shorter than what many treaties allow.
There’s also the United Nations Model Tax Convention, which is commonly used in treaties involving developing economies. It gives more taxing rights to the country where the activity happens. If you’re expanding into regions like Africa, South Asia, or Latin America, you’ll often see PE triggered earlier under these frameworks.
Two ideas sit at the center of any PE analysis.
First, the difference between where a company is based (residence) and where it operates (source). PE rules decide when the “source” country can step in and tax.
Second, profit attribution. Even if a PE exists, the host country only taxes the profits connected to that local activity, not the company’s entire global income. Figuring out how much profit belongs there is a separate challenge, and often where things get complicated.
Recent updates have made this even more relevant. In November 2025, the OECD expanded its guidance on how PE applies to modern working models, especially remote work.
The core definition hasn’t changed, but what qualifies as a “fixed place of business” in a world of home offices and distributed teams is now much clearer and, for many companies, much harder to ignore.
The Six Types of Permanent Establishment
Permanent establishment isn’t triggered in just one way. There are several recognized paths, each with its own logic, thresholds, and risk profile. Understanding which category your situation falls into is the first step in assessing exposure.
1. Fixed Place of Business PE
This is the most traditional form. If a business operates through a physical location in another country, it may create a PE.
Common examples include:
- Offices, branches, and factories
- Workshops, mines, oil wells
- Warehouses used for more than storage
Ownership isn’t required. What matters is control and continuity. If the company has the right to use a space and does so on an ongoing basis, it can qualify. In some cases, even a dedicated workspace inside a client’s office has been treated as a fixed place PE.
2. Dependent Agent PE
A company can create a PE without any physical presence if someone in the country is effectively acting on its behalf.
This typically applies when a person:
- Regularly concludes contracts, or
- Plays a key role in securing contracts that are finalized elsewhere
Following BEPS reforms, the threshold is broader than it used to be. It’s no longer necessary for the agent to formally sign contracts. If their actions consistently lead to deals being closed, that can be enough.
This often comes up with:
- Sales representatives
- Country managers
- Business development teams working under close direction
3. Construction and Installation PE
Construction or installation projects create PE once they cross a duration threshold.
- Under the OECD Model: typically 12 months
- Under the United Nations Model: often 6 months
The timeline starts when work begins on-site, not when the contract is signed.
Splitting projects into smaller contracts to stay below the threshold doesn’t always work. Anti-fragmentation rules allow authorities to combine related activities when assessing duration.
4. Service PE
In some cases, simply providing services in another country for long enough can create PE, even without a fixed location.
A common threshold is:
- 183 days within a 12-month period
In certain jurisdictions, this is calculated across all employees collectively. So a rotating team, each spending short periods in-country, can still cross the threshold when combined.
This is especially relevant for:
- Consulting teams
- Technical support functions
- Project-based deployments
5. Agency PE (Commissionnaire Structures)
Before BEPS, many companies used commissionnaire arrangements to avoid PE.
In these setups:
- A local entity sold goods in its own name
- The foreign company retained most of the economic benefit
This structure relied on the idea that contracts weren’t technically concluded by the foreign enterprise.
That gap has largely been closed. Today, if a local party plays the principal role in driving contracts, a PE can arise regardless of whose name is on the agreement. Structures built on this model often need reassessment.
6. Installation and Exploration PE
Some activities trigger PE under specialized rules.
- Supervisory roles tied to construction or installation projects can create PE independently
- Natural resource activities (oil, gas, mining) are often covered by separate provisions
Recent updates from the OECD have expanded guidance in this area, particularly for extraction-related activities. These rules reflect the long-term and high-value nature of such operations, and in some cases allow countries to apply lower thresholds.
Six Types of Permanent Establishment
What Does Not Create a Permanent Establishment
Understanding what triggers PE is only half the job. Just as important is knowing what doesn’t. Many companies end up over-restricting perfectly safe activities, adding cost and friction where no real tax risk exists.
Under Article 5(4) of the OECD Model Tax Convention, certain activities are explicitly excluded from PE. The reasoning is simple: they support the business, but they don’t represent the business itself being carried out in that country.
Storage, Display, and Delivery
Using a facility only for storing, displaying, or delivering goods does not create a PE.
A warehouse that handles logistics, without any involvement in sales or contract negotiation, typically falls within this exclusion. The key word here is only. The moment that location starts doing anything beyond logistics, the protection can fall away.
Purchasing and Information Gathering
A fixed place used solely for:
- Purchasing goods, or
- Collecting information
does not create PE.
This covers setups like procurement hubs, research offices, or liaison functions that gather market insights. The boundary is clear: once these activities move into decision-making or operational roles, the risk changes.
Preparatory or Auxiliary Activities
This is the broadest and most debated exclusion.
If a location’s activities are supportive rather than core to the business, it may not create PE. But this is where tax authorities look closely. If the activity contributes directly to revenue generation or value creation, it becomes harder to argue that it’s merely auxiliary.
Anti-Fragmentation Rule (Post-BEPS)
This is where things tightened significantly.
Before BEPS, companies could split functions across multiple entities or locations, each qualifying as “auxiliary” on its own. In practice, those pieces often formed a complete business operation.
The anti-fragmentation rule closes that gap. Activities are now assessed collectively across related entities in the same country, not in isolation. If the combined activity looks like a full business, the exclusions may no longer apply.
Activities That Usually Do Not Trigger PE
Some activities are commonly misunderstood but generally safe when kept within limits:
- Short-term business travel
- Attending conferences or meetings
- Occasional client visits
- Running a website accessible in another country
- Hosting servers or selling online (on their own)
- Working with a genuinely independent agent
These do not typically create PE under current OECD guidance, though digital business models can introduce additional complexity.
Where Companies Get It Wrong
The real risk isn’t misreading the rules, it’s letting activities evolve over time.
- A liaison office starts handling customer queries
- A warehouse team begins processing returns
- A procurement function starts negotiating contracts
None of these changes look significant in isolation. But together, they shift the activity from “support” to “core,” which is exactly where PE risk begins to emerge.
The 2025 OECD Update: Remote Work and the Home Office PE
In November 2025, the OECD released its most significant update to the Model Tax Convention since 2017. A key focus was long overdue: how permanent establishment applies to cross-border remote work.
Earlier guidance barely touched this issue. The updated commentary now gives tax authorities a clearer way to assess whether a remote employee’s home office can create a PE for their employer.
Importantly, the legal definition hasn’t changed. What’s new is how it’s interpreted in practice.
The Three-Step Framework
The updated guidance introduces a structured way to assess risk. The logic is sequential:
1. Is the arrangement sufficiently permanent?
Short-term or temporary setups generally fall outside PE.
- A few weeks or months abroad
- Sporadic remote work from another country
These typically don’t meet the threshold. The key question is whether the arrangement looks ongoing rather than incidental.
2. Does the employee spend more than 50% of their working time there?
If the employee spends less than 50% of their time in that location over a 12-month period, it’s usually not treated as a place of business.
Once that threshold is crossed, the analysis moves forward. Time alone doesn’t create PE, but it becomes a meaningful factor.
3. Is there a commercial reason for the location?
This is the decisive step.
If the employee is working from another country purely for personal reasons, lifestyle, family, or preference, PE risk is generally low.
If their presence serves a business purpose, the picture changes. Examples include:
- Managing client relationships locally
- Covering a key time zone
- Supporting market expansion or local operations
At that point, the home office starts to look less like a personal choice and more like part of the company’s operating footprint.
What Counts as a Commercial Reason
The distinction here is subtle but important.
The OECD makes it clear that internal benefits like employee retention or cost savings are not enough on their own.
Stronger indicators include:
- Proximity to customers or suppliers
- Regular in-person client interaction
- Alignment with key markets or regions
- On-ground coordination with affiliates
In other words, the test isn’t just where someone works, but why that location matters to the business.
The “Sole or Main Operator” Exception
There’s an important edge case.
If one individual is effectively delivering most or all of the company’s services in a country, the usual thresholds carry less weight.
For example:
- A consultant working almost entirely from a foreign home office
- A single employee responsible for a market
In these cases, the activity itself is concentrated in that location. That makes it much easier for tax authorities to argue that a PE exists, even if the broader framework might suggest otherwise.
What This Means in Practice
Cross-border remote work can no longer be treated as just an HR or mobility issue. It now has direct tax implications.
Any long-term arrangement where an employee works from another country should be assessed against this framework.
There is some alignment with other rules, for example, the 50% threshold mirrors elements of the EU Regulation 883/2004 used in social security coordination. But that’s where the consistency ends.
The OECD guidance itself isn’t binding law. Each country applies it through its own tax rules and treaty interpretations, which means outcomes can still vary across jurisdictions.
OECD 2025 — Three-Step PE Framework for Remote Work
PE in the Digital Economy
The traditional PE framework was built for a different kind of business environment — one defined by factories, offices, and physical distribution. Presence was tied to people and property. For decades, that worked.
The digital economy changed that completely.
A SaaS company can generate significant revenue in a country without a single employee, office, or server located there. A platform business can build a dominant market position through nothing more than a website and payment infrastructure. Under the conventional Article 5 framework developed by the OECD, none of this activity creates a PE. No physical presence means no taxable nexus.
The Policy Gap
This disconnect has been recognized for years. In 2015, the OECD’s BEPS Action 1 report identified the taxation of the digital economy as a major unresolved issue. It stopped short of redefining PE, opting instead for continued monitoring. That pause led to something predictable: countries started acting on their own.
Digital Services Taxes
In the absence of a global solution, several countries introduced Digital Services Taxes. Jurisdictions including France, the United Kingdom, Italy, Spain, and India began taxing digital revenues generated within their markets, regardless of whether a PE exists.
These taxes:
- Apply to gross revenue, not profit
- Target activities like advertising, intermediation, and data monetisation
- Sit outside traditional corporate tax systems
DSTs were never meant to be permanent. They were designed as pressure tools to push for a multilateral agreement. In practice, they have also introduced real double taxation risk, especially for large technology companies operating across multiple markets.
Significant Economic Presence
Some countries have gone further by redefining what presence means altogether. The Significant Economic Presence concept allows a country to tax a foreign business based on:
- Revenue generated locally
- Size of the user base
- Level of digital interaction
All of this can apply without any physical footprint.
For example:
- India applies elements of this approach through its equalisation levy framework
- Nigeria introduced SEP rules for non-resident digital service providers in 2020
The underlying idea is straightforward: if a company derives value from a market, it should contribute tax there, even if it operates entirely remotely.
Pillar One and Amount A
The most comprehensive attempt to address this issue is OECD Pillar One, specifically Amount A. Under this model:
- The largest multinational groups, revenues above €20 billion, profitability above 10%
- Must allocate part of their residual profit to countries where their customers are located
This shifts taxation away from physical presence and toward market-based allocation. Implementation remains uncertain. In 2025, the US government signaled that the OECD Inclusive Framework would not be binding domestically, complicating global adoption. As of 2026, negotiations are ongoing and no final multilateral agreement has been fully implemented.
What This Means for Digital Businesses
For now, there is no single consistent rule. Digital businesses operating internationally need to navigate a layered system:
- Traditional PE rules still apply where there is physical presence
- DSTs apply in countries that have introduced them
- SEP rules apply in jurisdictions that have adopted them
- Additional unilateral measures remain a live possibility
The key takeaway is simple but often misunderstood: no physical presence does not mean no tax exposure. Each country applies its own mix of rules. That means every market needs to be assessed on its own terms, not through a single global assumption.
Digital Economy — Layered Tax Compliance Landscape
Why PE Matters: The Real Consequences
Most companies treat PE as an abstract compliance risk until they encounter it directly. The consequences of getting it wrong are concrete, cumulative, and in some cases irreversible.
Corporate Income Tax Exposure
Once a PE exists, the host jurisdiction gains the right to tax the profits attributable to it under Article 7 of the OECD Model Tax Convention. Key points:
- The taxable amount is not your global profit, it is the profit connected to the PE’s activities
- Liability arises from the moment the PE came into existence, not from when it was discovered
- Retroactive exposure can span multiple tax years
Withholding Tax Obligations
A PE triggers withholding tax on certain payments between the PE and the head office or related parties. Payments that might otherwise flow freely under a tax treaty, interest, royalties, and service fees can become subject to local withholding rates. This directly affects intercompany cash flows and transfer pricing arrangements.
Payroll and Employment Law Compliance
PE status almost always triggers local registration requirements. The enterprise must:
- Register as an employer in the host country
- Operate a local payroll and withhold employee income taxes
- Remit social security contributions under local rules
- Comply with local labour law on termination, notice periods, and statutory benefits
For companies that assumed home-country employment arrangements covered their overseas employees, this can create significant retroactive liability.
Social Security Reassignment
Where employees work in a country where their employer has a PE, social security affiliation can shift from the home country to the host country. In the EU, Regulation 883/2004 governs which country’s system applies. A PE finding can retroactively reassign contributions, creating back-payment obligations for both employer and employee.
Double Taxation
Without proper planning, the same profits can be taxed in both the home and host countries. Double Taxation Agreements provide relief mechanisms, tax credits, exemptions, and mutual agreement procedures, but these require:
- Correct and timely application
- Coordinated filings across both jurisdictions
- Often lengthy dispute resolution processes
Where no DTA exists between the two countries, double taxation is not a risk, it is a near certainty.
Penalties, Interest, and Back Taxes
Tax authorities that discover an undisclosed PE do not assess tax from the current period forward. They go back to the year the PE first existed. Typical consequences include:
- Back taxes for every year the PE existed
- Interest charged on all unpaid amounts
- Penalties for non-compliance, which vary by jurisdiction but can be substantial
- In some countries, deliberate failure to register a PE is treated as tax evasion with criminal rather than civil consequences
The OECD’s BEPS framework has prompted many tax authorities to significantly increase PE audit activity, particularly around cross-border employment and intercompany service structures.
Reputational and Operational Risk
A PE enforcement action is not a private matter. The downstream effects can include:
- Damaged banking and investor relationships
- Loss of eligibility for government contracts
- Regulatory scrutiny in the home country for businesses in regulated industries
The reputational cost of a publicly disclosed PE dispute frequently exceeds the financial cost of the back taxes themselves.
PE Consequences — What Gets Triggered and Who It Affects
Real-World PE Cases and Enforcement
Understanding PE rules in the abstract is one thing. Seeing what happens when those rules are applied, or ignored, makes the stakes tangible.
The pattern across every enforcement case is consistent: tax authorities look past the legal structure to the operational reality. How decisions are actually made, where contracts are effectively concluded, and where value is genuinely created determines the outcome, not what the contracts say on paper.
Real-World PE Enforcement — Case Reference
Google vs. France
France pursued Google for over €1 billion in back taxes, arguing that Google’s Irish entity had a dependent agent PE in France through its local sales operations.
Key facts:
- French tax authority argued Google France was effectively concluding contracts on behalf of Google Ireland
- In 2019, a French administrative court ruled in Google’s favour
- Google Ireland was found not to have a PE in France under the applicable treaty
The lesson: a company can generate substantial economic activity in a market and face no corporate tax there, simply because its legal structure keeps the contracting entity offshore. That gap is precisely what BEPS Action 7 was designed to close.
Apple and Italy
Italian prosecutors investigated Apple over allegations that profits had been channelled through Ireland to avoid Italian tax.
Key facts:
- In December 2015, Apple reached a €318 million settlement with Italian authorities
- The settlement covered back taxes and penalties for 2008 to 2013
- The case ran alongside the European Commission’s €13 billion state aid ruling against Apple’s Irish tax arrangements in 2016
The lesson: treaty-based PE planning does not insulate a company from broader regulatory scrutiny. PE disputes and state aid investigations can run simultaneously, compounding both financial and reputational exposure.
Philip Morris and Italy
Italian tax authorities argued that Philip Morris International’s local distributor, operating under close direction from the parent, constituted a dependent agent PE.
Key facts:
- Authorities found sufficient evidence of parental control over the distributor’s activities
- PE status was asserted, resulting in significant financial penalties and reputational damage
- The distributor’s contractual independence was not supported by operational reality
The lesson: operational independence must be real, not just documented. Tax authorities assess how decisions are actually made, not what the agency agreement says.
Roche Vitamins and Spain
This case went the other way, and shows what a successful PE defence looks like.
Key facts:
- Roche Vitamins demonstrated that its Spanish subsidiary made its own commercial decisions and bore genuine economic risk
- The subsidiary did not habitually conclude contracts on behalf of the Swiss parent
- Spanish authorities accepted independent agent status under Article 5(6) of the applicable treaty
- No PE was found
The lesson: genuine governance structures and documented operational autonomy are effective defences, but they must be evidenced, not merely asserted.
The Broader Enforcement Trend
These cases are not outliers. Several structural shifts have made PE enforcement more aggressive across the board:
- The OECD BEPS project has directly incentivised tax authorities to increase PE audit activity
- Many jurisdictions have created dedicated transfer pricing and PE audit units
- The EU Anti-Tax Avoidance Directives have strengthened the legislative toolkit for European authorities
- The post-pandemic expansion of remote work has created a new category of PE exposure involving far more companies than traditional enforcement targets
Managing and Mitigating PE Risk
PE risk is not eliminated by avoiding foreign markets. It is managed by understanding exactly which activities create exposure and structuring operations accordingly before entering a new jurisdiction — not after a tax authority raises questions.
Conduct a PE Assessment Before Every Market Entry
The starting point is a structured review of planned activities against the PE rules in the target jurisdiction. That means examining the applicable tax treaty, the domestic law fallback where no treaty exists, and any deviations from the OECD Model that the host country has adopted through the Multilateral Instrument.
The assessment should cover:
- What activities will be performed and by whom
- Whether any personnel will have authority to conclude or lead to contracts
- Whether any fixed location will be used and for how long
- Whether service delivery will exceed duration thresholds
- Whether the anti-fragmentation rule could aggregate activities across related entities
Structure Agent and Contractor Relationships Carefully
Dependent agent PE is one of the most common and most avoidable triggers. The key is ensuring that local representatives, whether employees, contractors, or distributors, operate with genuine independence and do not habitually conclude contracts or play the principal role in concluding contracts on behalf of the foreign enterprise.
Contracts should explicitly define the scope of authority. More importantly, operational reality must match the contract. As the Philip Morris case demonstrated, a contractual independence clause is worthless if the day-to-day relationship tells a different story. Regular governance reviews, documented decision-making trails, and clear reporting lines that reflect actual authority are essential.
Track Time and Activity for Every Cross-Border Worker
The 2025 OECD guidance has made time tracking operationally consequential in a way it never was before. The 50% working time threshold means companies need reliable data on where each cross-border employee is working and for how long. Relying on self-reporting or travel expense records is not sufficient.
This means:
- Implementing digital tools that log working location by day
- Setting internal thresholds below the 50% mark as an early warning trigger
- Building cross-border work approval processes that include a PE assessment step
- Maintaining records that can be produced to a tax authority if challenged
Use Employer of Record Services Strategically
An Employer of Record employs workers on behalf of a foreign company in a jurisdiction where that company has no legal entity. Properly structured, an EOR arrangement separates the foreign enterprise from direct employer status in the worker’s country, reducing fixed place of business and dependent agent PE exposure.
EOR is not a blanket PE solution. It addresses employment-related PE risk effectively. It does not eliminate PE risk arising from sales activities, contract authority, or long-term service delivery. Companies using EOR services still need to assess whether the underlying business activities, not just the employment relationship, create PE exposure independently.
Apply the Preparatory and Auxiliary Carve-Out Deliberately
Where activities genuinely qualify as preparatory or auxiliary under Article 5(4), structuring operations to remain within that carve-out is a legitimate and effective strategy. Liaison offices, market research functions, and procurement hubs that stay within their defined scope can operate without creating PE.
The discipline required is ongoing. These activities must be monitored regularly to ensure they have not drifted into operational territory. A single employee who begins answering customer queries or negotiating supply terms can convert an excluded activity into a PE trigger without any deliberate decision being made.
Engage International Tax Counsel Early
PE analysis is jurisdiction-specific, treaty-specific, and fact-specific. General principles provide orientation but do not substitute for advice tailored to the exact activities being planned in the exact jurisdiction being entered.
Engaging qualified international tax counsel before operations begin, rather than after a tax authority raises questions, is consistently the most cost-effective approach.
The OECD’s transfer pricing guidelines and the UN Practical Manual on Transfer Pricing are also relevant resources for companies that have already triggered PE and need to establish a defensible profit attribution position.
PE Risk Mitigation Playbook — Six Actions
Country-Specific PE Variations
The OECD Model provides the global baseline. But every country interprets, adapts, and in some cases significantly departs from it. For companies operating across multiple jurisdictions, local divergence matters as much as the standard itself.
Country PE Variation Tracker — Six Key Jurisdictions
India
India is one of the most aggressive PE enforcement jurisdictions globally.
Key divergences from the OECD standard:
- Service PE threshold in many Indian treaties is as low as 90 days — well below the OECD’s 183-day benchmark
- Domestic tax law defines “business connection” broadly, often capturing arrangements that would not trigger PE elsewhere
- The equalisation levy extends tax reach to non-resident digital businesses with no physical presence
The Central Board of Direct Taxes takes an expansive view of PE and enforcement has intensified. Companies sending employees for project work, technical services, or management oversight need to count days carefully and review the applicable treaty in detail.
Germany
Germany follows the OECD Model closely but applies it with precision. The Bundeszentralamt für Steuern takes a strict view on what qualifies as preparatory or auxiliary, and German courts have consistently rejected broad claims of exemption.
Key points:
- Germany has implemented the MLI — pre-BEPS commissionnaire structures using German distribution entities are now directly exposed
- Construction PE thresholds can fall below twelve months under older bilateral treaty agreements
- Fixed place of business assessments are fact-intensive and rigorously scrutinised
United States
The US is not a signatory to the OECD Multilateral Instrument, which creates a structurally different landscape.
Key points:
- US treaties have not been automatically updated by the MLI — PE analysis must be conducted treaty-by-treaty
- Where no treaty exists, the IRS applies the effectively connected income standard, which operates differently from but can overlap with PE concepts
- IRS scrutiny of cross-border intercompany service structures and transfer pricing arrangements has increased materially
China
China’s State Taxation Administration applies PE rules with significant enforcement discretion and a substance-over-form approach.
Key divergences:
- Construction PE thresholds in most China treaties are set at six months, not twelve
- Service PE applies at 183 days but enforcement is vigorous and fact-driven
- Management and control functions exercised by a foreign parent over a Chinese entity can trigger PE questions independently of physical presence
- Representative office activities are interpreted narrowly — the boundary between permitted activity and PE is closely policed
United Arab Emirates
The UAE introduced a federal Corporate Tax regime in June 2023, making PE analysis relevant for the first time.
Key points:
- Foreign companies with a PE in the UAE are now subject to 9% corporate tax on attributable profits
- The UAE follows OECD principles in defining PE and has an expanding DTA network
- Companies with employees, project sites, or agents in the UAE need PE assessments that simply were not required before 2023
United Kingdom
The UK operates its own treaty network independently post-Brexit. HMRC applies OECD-based PE rules and has ratified the MLI.
One critical UK-specific feature:
- The Diverted Profits Tax applies a 25% rate to profits artificially diverted from the UK — including through structures that successfully avoid PE
- This creates dual exposure: a company can argue no PE exists and still face DPT liability if HMRC concludes profits have been diverted
- The interaction between PE rules and DPT makes UK structuring particularly nuanced for multinationals with significant UK market activity
PE vs. Subsidiary vs. Branch vs. EOR: The Entry Structure Decision
When a company enters a foreign market, the structure it chooses determines its tax exposure, liability profile, speed, and cost. PE is not just a risk to manage, for many businesses it is the structure they are operating through without realising it.
Permanent Establishment / Branch
A branch is an extension of the parent company, not a separate legal entity. The parent bears full liability for its obligations and there is no structural insulation between the two.
From a tax perspective, a branch creates PE immediately. Profits attributable to it are taxed in the host country from day one.
Branches are relatively straightforward to establish, but the direct liability exposure makes them most appropriate where the parent is comfortable operating without a legal buffer between itself and the host jurisdiction.
Subsidiary
A subsidiary is a separate legal entity incorporated in the host country. It provides liability insulation, the parent’s exposure is generally limited to its equity investment.
A subsidiary does not automatically create PE for the parent. However, under OECD Article 5, it can still constitute a dependent agent PE if it habitually concludes contracts on the parent’s behalf.
Subsidiaries require full local incorporation, governance, and compliance infrastructure. They are best suited for established, long-term market presence at scale where the operational investment is justified.
Employer of Record
An Employer of Record allows a foreign company to hire employees in a country without establishing a local entity. The EOR is the legal employer, handling payroll, tax withholding, benefits, and labour law compliance.
Properly structured, an EOR arrangement reduces fixed place of business and dependent agent PE exposure significantly. It does not eliminate PE risk entirely, if the employee’s activities independently trigger PE through sales authority or contract conclusion, the underlying business exposure remains.
EOR is the fastest and most flexible entry option. It works best for market testing, small headcounts, or jurisdictions where entity setup is disproportionately slow or complex.
Representative Office
A representative office is a limited-purpose presence permitted in some jurisdictions, typically for liaison, market research, and promotional activities only. It cannot generate revenue or conclude contracts.
Where activities genuinely stay within these boundaries, a representative office falls within the preparatory and auxiliary exclusions under Article 5(4) and does not create PE.
Activity drift is the primary risk. Any step into commercial activity, answering sales queries, facilitating contract negotiations, supporting pricing decisions, converts excluded status into PE exposure without any formal structural change.
How to Choose
The right structure depends on the speed of entry needed, the scale of planned operations, the nature of the activities being conducted, and the parent’s appetite for direct legal and tax exposure in the host country.
No structure eliminates all tax risk. Every option carries trade-offs between speed, cost, liability, and compliance burden. The decision should be made with full awareness of what PE exposure each structure carries, not just what it costs to set up.
