One Employee Working Abroad Can Create a Tax Presence
Permanent establishment rules decide when a company becomes taxable in a country it never intended to operate in. Remote work has made the question far more common than it used to be.
The Threshold Question
A country generally taxes a foreign company only if that company has enough presence to justify the claim. The concept defining enough is permanent establishment, and it appears in domestic law and in nearly every double taxation treaty.
The purpose is to draw a line. A company selling into a country from abroad is not taxable there. A company operating a factory there plainly is. Permanent establishment rules determine where between those poles the obligation begins.
Permanent establishment does not require an office, a subsidiary or a decision to enter a market. It can be created by what a single person habitually does.
The Two Main Routes
Treaty definitions generally recognise two ways a presence arises.
A fixed place of business exists where the company has premises at its disposal through which business is carried on, with some degree of permanence. An office, a branch, a workshop or a factory qualifies. Purely preparatory or auxiliary activities, such as a warehouse used only for storage or an office used only to gather information, are typically excluded.
A dependent agent permanent establishment arises where a person acting on the company behalf habitually concludes contracts, or habitually plays the principal role leading to contracts routinely concluded without material modification. This second formulation, broadened in recent treaty revisions, is the one that catches remote sales activity.
| Activity abroad | Risk level |
|---|---|
| Storage or display of goods only | Generally excluded |
| Market research and information gathering | Usually auxiliary |
| Engineering work for internal products | Depends on facts and duration |
| Negotiating and closing customer contracts | High risk |
| Managing local staff and operations | High risk |
Why Remote Work Changed the Exposure
Traditionally a company knew where it operated because it chose those locations deliberately. Employees relocating on their own initiative, working from a home the company has never seen in a country it has no plans to enter, breaks that assumption.
The tax analysis does not care about intention. It looks at what the person does, how long they do it, and whether the arrangement has sufficient permanence. An employee working abroad for a few weeks is very unlikely to create a taxable presence. The same employee resident there for two years, concluding customer contracts, presents a materially different question.
Home offices complicate the fixed place test. Authorities have taken the position that a home office can be at the disposal of the employer where the employer requires or expects the work to be done there, particularly if the company provides no alternative workspace in that country.
What Follows a Permanent Establishment
The consequences extend well beyond a single tax return. The company must register with the local authority, file returns, and attribute an appropriate share of profit to the establishment, which is itself a transfer pricing exercise requiring analysis and documentation.
Payroll obligations frequently arise independently, since employment tax and social security rules follow their own tests and can be triggered at lower thresholds than corporate tax. Value added tax registration may follow. And penalties for late registration accumulate from the date the obligation arose, not from the date the company noticed it.
The administrative cost of compliance in a country where the company has one employee and negligible profit routinely exceeds the tax itself.
How Companies Manage It
Practical responses fall into a few categories. Many companies maintain an approved list of countries where they already have entities and permit remote work only there. Others impose day count limits per country and track them, which is imperfect since duration is only one factor.
Where an employee is valuable enough to accommodate, companies use an employer of record, a third party that legally employs the person locally and handles payroll and compliance, or they establish a local entity if the headcount justifies it.
Restricting duties is the other lever. Employees abroad may be prohibited from signing contracts or negotiating terms, since the agent route depends on what they do rather than on where they sit.
The Bottom Line
Permanent establishment rules were written for a world where companies chose their locations, and distributed work has pushed them into situations they were not designed for. The exposure is driven by duration, permanence and above all by whether the person is concluding or substantially negotiating contracts. For most employers the binding constraint is not the tax owed but the compliance obligations that follow, which is why policy responses tend to restrict where people may work rather than attempt to manage the liability afterwards.
