Permanent establishment risk is the possibility that employing someone in another country gives your company a taxable presence there. It is decided by what the person does, not by which payroll route paid them.
It is about activity, not about payroll
The question is whether your company has a fixed place of business or a dependent agent habitually concluding contracts in that country. Those tests look at the substance of the role, so the arrangement that paid the person does not settle it. Treaties, where one applies, set out the tests and the exclusions, and the detail differs between them.
The roles that raise the question
Sales people who negotiate and close, country managers with real authority, and anyone holding themselves out as running a local operation. Back office, support and engineering roles are ordinarily lower risk, though nothing is automatic. The reliable signal is authority: the more a role can bind the company locally, the sharper the question becomes.
An employer of record does not make it go away
This is the most common misunderstanding in the category. An EOR employs the person lawfully and handles local payroll and benefits; it does not change what the person does for your business. Good providers say so plainly. Treat the EOR as solving employment compliance and keep the presence question under separate review.
Document the role and review it as it grows
Write down what the person is authorised to do and what they are not, keep the contract and the job description consistent with it, and revisit when the role changes. Risk usually accumulates quietly, as a support hire gradually starts negotiating. Where the answer matters, take local tax advice rather than relying on a general rule.
Questions people ask about permanent establishment risk
Does one remote employee create a permanent establishment?
Not automatically. It depends on what they do, where they do it and which treaty applies, if any.
Is a home office a fixed place of business?
It can be in some circumstances, particularly where the company effectively requires it and the work is core. It is fact specific.
How is this usually managed?
By limiting authority in the role, documenting it, and taking local advice for senior or revenue-generating positions.
