Few cross-border exposures accumulate as quietly as a permanent establishment. Nothing is filed to create one, nothing is registered to announce it, and in most cases no single decision can be identified afterwards as the moment it came into being. A group signs its contracts at head office, issues its invoices from head office and books its revenue at head office, and concludes from this that it is taxable only at head office. The treaty test asks a different question: where, and through whom, is the business actually carried on. The distance between those two questions is where most permanent establishment assessments are found.
What the concept actually captures
A permanent establishment is a threshold. It marks the point at which the state where an enterprise operates, but is not resident, acquires the right to tax the business profits attributable to that operation. In treaty practice the definition sits in Article 5 of the applicable convention, with the taxing right and the attribution rule in Article 7. Alongside it sits the domestic law definition of the source state, which determines whether there is anything for the treaty to relieve in the first place. The United Kingdom definition stands on its own and is displaced by the treaty; the Dutch one adopts the treaty concept wherever a treaty applies and keeps its own wording only for relations that no treaty governs.
Two features make the concept awkward in practice. The first is that it is factual rather than formal. It does not depend on incorporation, registration, a bank account or a signature block; it depends on premises, people and patterns of conduct that are usually established by operating managers rather than by the finance function. The second is that the definition is not uniform. Each treaty is negotiated, and conventions depart from the model in both directions, with different durations for construction sites across a single treaty network. The Multilateral Instrument has amended many bilateral treaties, and by design not symmetrically: a state may reserve out of the permanent establishment articles, and where one of them replaces an existing treaty provision it applies only if both contracting jurisdictions notified that provision. The operative text has to be read as modified rather than as originally signed, and traced to the positions the two states deposited, which is why the synthesised texts administrations publish state that the authentic texts take precedence over them.
The fixed place of business
The primary limb requires a place of business, a degree of permanence, and business carried on through that place. Ownership is irrelevant. What matters is whether the place is at the disposal of the enterprise, and on that test it makes no difference whether the use is exclusive or shared, or whether the enterprise owns the place, rents it or occupies it with no right at all. The condition is satisfied more often than groups expect: a dedicated room within a client’s premises, desk space held continuously at a distributor, a site office, a workshop, in certain circumstances an equipment arrangement. Permanence is assessed by the character of the presence rather than by any single calendar figure, with six months as a working benchmark and exceptions for recurrent activity and for a business carried on exclusively in that country, so recurring seasonal use of the same location can qualify where isolated use would not.
The commercial reality that catches groups out is incremental. A representative presence opened to support a single customer acquires a second customer, then a technical function, then a manager with local authority. No step is significant on its own. The aggregate is a place through which the business of the enterprise is conducted.
Projects of extended duration
Construction, installation and assembly sites are dealt with by a specific rule that turns on duration. The threshold period is set by the applicable treaty and varies between conventions, so the only reliable statement is that it must be read in the instrument governing the relationship, not assumed from a model text or from another group company’s experience. Domestic law is often the broader of the two and is then overridden: United Kingdom law counts building sites and construction or installation projects without any duration qualification, while the Dutch rule for relations outside a treaty sets twelve months.
How the period is counted matters more than the length of any one contract. Time is measured by reference to the site or project rather than the contract, so a site is a single unit even where several contracts are involved, provided it forms a coherent whole commercially and geographically. Preparatory work on site counts, and temporary interruptions, seasonal or otherwise, are ignored. Subcontractor time is attributed to the general contractor. Dividing a single project into shorter contracts held by related entities is addressed directly by Article 14 of the Multilateral Instrument, which adds to the contractor’s own time the periods, each exceeding 30 days, in which closely related enterprises carried on connected activities at the same site, although a state may reserve the right not to apply that article at all. Where the convention contains an express services provision, the furnishing of services by personnel may create a presence on its own terms, without any site at all, typically once an individual has been present for more than 183 days in a twelve month period.
The dependent agent
The second limb dispenses with premises entirely. Where a person acts on behalf of an enterprise and habitually concludes contracts, or habitually plays the principal role leading to the conclusion of contracts that are then routinely entered into without material modification, that enterprise may be treated as having a permanent establishment in respect of the activities that person undertakes for it. That is Article 12 of the Multilateral Instrument, which names commissionnaire arrangements in its title and deliberately reaches conduct short of signature. The same wording is now the United Kingdom domestic test for chargeable periods beginning on or after 1 January 2026 and the Dutch test outside treaty relations. It is not universal at treaty level: the United Kingdom and Netherlands convention keeps the older test of an agent who has and habitually exercises an authority to conclude contracts, while taking on the anti-fragmentation rule and the definition of a closely related person.
The exception for independent agents has narrowed correspondingly. An agent acting exclusively or almost exclusively on behalf of closely related enterprises will not generally qualify as independent, as section 1142 of the Corporation Tax Act 2010 and the corresponding Dutch paragraph now provide, which removes a defence that intragroup sales companies once relied upon. In practice the analysis is evidential rather than contractual: what the local team’s correspondence, pricing discretion, discount approvals and customer expectations show about who decided the deal.
A permanent establishment is not created by a decision. It is created by a pattern of behaviour, and it is usually identified by someone other than the taxpayer.
What does not usually cross the threshold
Activities of a preparatory or auxiliary character are excluded. The traditional list covers the use of facilities solely for storage, display or delivery, the maintenance of stock for those purposes or for processing by another enterprise, purchasing goods, collecting information, any other activity of that character, and combinations of those activities. In domestic law the same idea appears as examples that illustrate the general expression without limiting it. Whether each listed activity is additionally subject to an overarching condition that it be genuinely preparatory or auxiliary when viewed against the business as a whole depends on what the two states chose: Option A of Article 13 of the Multilateral Instrument imposes that condition on every listed activity, Option B preserves the list as it stands, a state may choose neither, and an Option modifies a convention only where both chose the same one.
That qualification does real work. A warehouse is auxiliary to a manufacturer whose value is created elsewhere; the same warehouse may be an essential part of a distribution business whose proposition is delivery speed. The criterion is whether the activity forms an essential and significant part of the enterprise as a whole. Anti-fragmentation rules prevent a cohesive operation from being divided into separately harmless components held by connected parties in the same jurisdiction, and they now sit in the treaties, in the Dutch act and in the United Kingdom rule on fragmented business operations alike. The exclusions should therefore be treated as a conclusion reached after analysis, not as a category to which a function can simply be assigned.
Attribution of profit and the obligations that follow
Recognition of a permanent establishment is the beginning of the exercise rather than its end. The attribution analysis treats the establishment as a separate and independent enterprise engaged in the same or similar activities under the same or similar conditions, takes account of the functions performed, the assets used and the risks assumed through it and through the rest of the enterprise, recognizes its dealings with those other parts, and assumes, as the United Kingdom attribution rule puts it, such equity and loan capital as it could reasonably be expected to have. The pricing of those dealings answers to the same arm’s length standard that applies between associated enterprises, with the documentation duties that accompany it; groups with Dutch entities in the chain will recognize the analysis from the article 8b documentation obligation, a records requirement that applies without a size threshold.
The consequences are broader than a corporate return. A foreign legal person with a branch here is entered in the trade register; a non-resident employer becomes a Dutch wage tax withholding agent so far as it has a permanent establishment or a permanent representative here, on a definition that borrows the corporate one and adds cases of its own; and the fixed establishment for indirect tax is a separate test again, of sufficient permanence and a suitable structure of human and technical resources, which a VAT number alone does not create. Social security obligations for the personnel involved and adjustment of the home state’s relief mechanism may follow as well. Where the establishment is identified retrospectively on audit, the practical difficulty is rarely the quantum of attributed profit, which is often modest for a sales or support presence. It is the accumulated interest, penalties and late filings, the reopening of positions in the home state, and the evidential problem of reconstructing what people did in years for which nobody kept records for that purpose.
Remote work and distributed teams
The question has become materially more common because the underlying facts have changed. An employee who relocates and continues to work for the same employer raises the fixed place limb directly: whether the space used is at the disposal of the enterprise, and whether the presence is permanent enough. The worked examples published for mobile employees show where that line falls. A few weeks in an affiliate’s office, repeated once, fails the permanence test; a contractual right to spend a fixed three month period in the country each year meets it, as does a rotation of six colleagues through one office over nine months, because the changing identity of the personnel does not interrupt the employer’s presence. Permanence settles only that condition; the rest still have to be examined. An occasional accommodation of personal circumstances sits differently from a role for which no office exists.
Where the relocated employee has a commercial or customer-facing function, the agent limb becomes the more serious exposure, and it requires no office at all: a salesperson visiting clients has no fixed place of business, because the clients’ premises are not at the disposal of the employer, and may still create a dependent agent presence. Senior personnel abroad raise a further question about where management functions are actually exercised, which touches residence and substance as well as establishment; the considerations overlap with the substance expectations applied to Dutch entities. Payroll withholding, social security coordination and permanent establishment are three separate tests with different criteria: the wage tax definition starts from the corporate one and extends it, while the coordination rules subject a person to the legislation of a single member state, in principle the one where the activity is pursued, subject to the posting and multi-state provisions. A comfortable answer on one carries no implication for the others.
Managing the exposure before it is assessed
The controls that work are administrative rather than technical. Groups that avoid unpleasant findings tend to maintain a delegation of authority reflecting who genuinely decides commercial terms, to keep contract approval and pricing discretion where the legal structure says they sit, to record the location and duration of project personnel while the projects are running, to require review before an employee relocates rather than after, and to revisit the position whenever a representative function grows. Board composition, meeting practice and mandate design belong to the same discipline, and are addressed in our note on governance design for Dutch holding companies.
Where a taxable presence is unavoidable, or commercially desirable, the sensible response is to establish it deliberately, with a defined functional profile, an attribution basis prepared in advance and contemporaneous documentation, rather than to discover it several years later on someone else’s terms.
