Permanent establishment, often abbreviated to PE, is a tax concept used to determine whether a business has a sufficient presence in another jurisdiction for that jurisdiction to tax certain business profits. It can become relevant when a company opens premises, sends people abroad, delivers projects or gives a local representative commercial authority. A company does not necessarily need to incorporate a subsidiary before the question arises.
For businesses hiring internationally, the key distinction is between employing a person compliantly and assessing the customer’s corporate tax position. An Employer of Record can provide an employment arrangement, but its involvement does not automatically prevent the customer from having a PE. Read this guide alongside what an EOR is and the relevant country directory before treating employment administration as the complete market-entry solution.
Begin with domestic law and the actual treaty
The analysis starts with the relevant domestic tax rules and any applicable tax treaty. A treaty may restrict a country’s taxing rights, but eligibility for treaty protection and the precise wording must be checked. If no treaty applies, it is unsafe to assume that a familiar model-convention threshold governs the arrangement.
The OECD and United Nations publish model conventions that inform treaty negotiation and interpretation. They are not substitutes for the agreement between the two countries involved. The UN’s explanation of its model illustrates that treaty models can take different approaches to allocating taxing rights. Protocols and subsequent instruments can also affect an existing treaty’s operation.
Give advisers the identity and tax residence of the enterprise, the country of activity, the proposed start date and the business model. Ask them to identify the domestic provisions, treaty articles and effective dates they are applying. A conclusion that merely says “below the threshold” is incomplete unless it explains which threshold and which activities were assessed.
Fixed place of business
One common route to PE is a sufficiently fixed place through which an enterprise carries on business. An office or branch is an obvious candidate, but the analysis is not confined to premises owned by the company. The use of space, its connection with the enterprise and the nature and duration of activity matter.
HMRC’s treaty guidance on permanent establishment describes the fixed-place concept and the separate dependent-agent route. For procurement, the practical implication is to record where work will actually happen. “Remote employee” tells an adviser less than a factual explanation of who chooses, funds and uses the location.
Ask whether the company requires a particular office, advertises a local address, stores stock or equipment there, or holds customer meetings at the premises. These questions collect relevant facts; none should be treated as a universal automatic trigger. The legal assessment must consider the applicable definition and the overall circumstances.
Home offices and remote work
A home office does not automatically become the foreign company’s PE whenever an employee works there. Conversely, describing a location as the employee’s private home does not automatically exclude it. The reason for working from that country, the pattern of use and the enterprise’s commercial connection with the location deserve careful assessment.
The OECD’s 2025 update addresses cross-border remote work. Its 2026 explanation discusses working patterns and commercial reasons for presence. This is interpretive guidance in a treaty context, not a blanket exemption that every country automatically applies to every remote worker.
An employee choosing to spend time abroad for personal reasons presents different facts from a business recruiting someone specifically to serve that market. Document the actual reason rather than selecting whichever explanation sounds safer. If the role changes from internal support to local customer development, revisit the assessment even if the employee remains at the same desk.
Dependent agents and contract authority
A business can also face PE questions because of the activities of a person acting on its behalf. Depending on the applicable rules, formal authority to sign contracts is not the only issue. Someone who routinely drives negotiations to a point where headquarters approves without meaningful changes may require attention even if the signature occurs elsewhere.
The UK provides a current example of why dates matter. HMRC’s domestic PE guidance explains an updated dependent-agent definition for chargeable periods beginning on or after 1 January 2026, including certain principal-role activities leading to contracts. That is a UK-specific development; other jurisdictions and treaties require their own analysis.
Map the sales process. Who finds prospects, agrees scope, negotiates price, resolves objections and authorises deviations? Preserve evidence of substantive decisions rather than relying only on a signature policy. If a written delegation says the local representative has no authority but commercial teams routinely accept their negotiated deals, advisers need to know.
Services and project provisions
Some treaties contain provisions under which sustained services or particular projects can create a PE without the same fixed-place analysis. Construction and installation work can have distinct rules. Service provisions may use day counts or conditions concerning projects and personnel, but the exact wording differs. There is no single international duration that answers every case.
HMRC’s guidance on services provisions notes the importance of the applicable treaty actually containing the relevant provision. A model or commentary example does not by itself insert a service threshold into a bilateral agreement. Read the provision before designing a travel or project policy around it.
Track activity at the enterprise and project level where required, not merely employee by employee. Rotating different staff members can leave a continuous commercial activity in place. Ask how related projects, overlapping days, subcontractors and interruptions are treated. A spreadsheet that counts each traveller’s days separately may miss the question the treaty asks.
Why 183 days is not a universal safe harbour
The number 183 appears in several international tax contexts, but it does not create a general permission to conduct business abroad without consequences. Employment income, individual tax residence, service PE and other provisions can use different counting periods and additional conditions. A test designed for one issue cannot be borrowed to answer another.
A company should therefore avoid policies stating that overseas work is automatically safe below 183 days. Some PE questions turn on a place or commercial authority rather than that threshold. Payroll withholding, social security, immigration and employment-law requirements may arise independently. Each should have its own assessment rather than sharing a single travel counter.
Ask the adviser to separate the conclusions: corporate PE, corporate residence, individual income tax, payroll, social security, immigration and indirect tax. That makes it possible to understand what an approval covers. A favourable answer on one topic should not silently become an approval of the whole arrangement.
What an EOR changes and what it does not
An EOR introduces a local employer and an employment-services relationship. That can address important practical problems, including contracts and payroll administration. It does not change the commercial substance of the customer’s business merely because a different company pays the individual. The worker may still perform activities relevant to the customer’s PE analysis.
For example, an EOR-employed representative who develops and negotiates local sales needs assessment based on those activities. The employing company’s identity is part of the facts, not a complete defence. Similarly, a customer’s use of a workplace or a sustained service project may remain relevant despite employment being outsourced.
Ask prospective providers exactly what their tax support includes. Do they gather facts, refer to an adviser, provide a written country assessment or simply administer payroll? Do their contracts exclude the customer’s corporate tax exposure? Our global EOR directory can help identify candidates, but the tax question should be scoped separately from provider selection.
Contractors and intermediaries do not remove the question
Using an independent contractor can change the contractual structure without necessarily removing all PE concerns. The person’s authority, activities and relationship with the enterprise may still need review. Independence for an agency provision is a specific legal issue, and should not be assumed merely because the worker submits invoices or operates through an intermediary.
Worker classification is a related but separate topic. Our employee misclassification guide explains why a contractor label may be inconsistent with actual working practices. A Contractor of Record may administer a commercial engagement, but it does not grant an exemption from corporate tax rules.
Include all relevant people when mapping the business presence: employees, contractors, directors, consultants and other representatives. The tax adviser needs to understand who performs the enterprise’s functions, not just who appears in its payroll report. Separate procurement channels should not produce separate factual pictures of the same operation.
What happens if a PE exists
A PE conclusion does not necessarily mean the entire worldwide profit becomes taxable in the host country. Profit attribution is a further analysis. HMRC’s business profits guidance describes attributing profits on the basis of the PE’s activities and a separate-enterprise approach in the treaty context. The applicable law and treaty remain decisive.
The business may need registrations, returns, records and a method for identifying relevant income and expenses. Penalties or interest can depend on missed obligations and local rules. Double-tax relief may be available under domestic law or treaty provisions, but timing, documentation and entitlement need attention. The administrative burden can matter even where net additional tax is limited.
Treat the finding as an operating decision. Sometimes the sensible response is to register and comply rather than redesign a commercially necessary activity solely to avoid presence. Compare that route with forming a subsidiary or changing the genuine scope of operations. Artificial paperwork changes are unlikely to provide a durable solution.
A proportionate pre-hire assessment
Before approving an international role, collect a concise business description, job duties, reporting lines, work locations and anticipated travel. Include customer-facing activity, pricing authority, contract involvement, use of premises and expected duration. Ask the business sponsor to confirm the information, because a generic job title can conceal materially different responsibilities.
Then obtain a written assessment identifying assumptions, uncertainties and actions. A useful conclusion explains what would change the answer. For example, an adviser might require a new review if the employee begins negotiating contracts or the company leases a dedicated office. Those triggers should be translated into instructions the manager can recognise and follow.
Keep the assessment with the hiring approval and review it when circumstances change. The purpose is not to freeze a role indefinitely; it is to make commercial changes visible before they create unplanned obligations. Finance, legal, HR and the business leader should know who owns the review and the next decision.
Monitoring an expanding operation
Early hiring arrangements often evolve. A single support employee becomes a team, a home-office arrangement becomes shared premises, or occasional customer meetings become a permanent sales function. Review the operation as a whole rather than extending the original assessment to each new hire without reconsidering the accumulated presence.
Build practical reporting into existing workflows. Travel approvals can collect location and duration; sales systems can show negotiation authority; procurement can identify office leases; HR can flag changes in duties. Those records should support a consistent account of what the enterprise does locally. A policy document alone cannot show how the business operated during a tax period.
When an issue is discovered, preserve records and seek advice on the period affected, registration requirements and any correction process. Do not backdate a different account of the working arrangement. Clear contemporary facts help advisers distinguish a manageable compliance obligation from a more significant historical problem.
Making the hiring decision
PE is one component of international expansion, alongside employment, immigration, data protection and operating permissions. The right answer may be EOR, direct employment, a local entity or a different commercial model. Compare those options using the real role and growth plan, then understand which risks each arrangement addresses and which remain with the business.
Use our UK, Brazil and other country directories to explore employment providers after defining the structure you need. Read EOR versus PEO if the service labels are unclear. Provider coverage is useful procurement information, but it does not establish a tax conclusion about your enterprise.
A sound decision rests on accurate facts, the applicable rules and an operating plan that matches both. Do not seek a universal guarantee that a payslip provider, short visit or overseas signature eliminates PE. Ask instead which activities create exposure, how obligations will be met and when the assessment needs to be revisited.
