Your employer’s real worry is not whether you can work from Spain. It is whether your spare room makes them taxable there. Here is the binding ruling that answers it, the facts it turned on, and how to put those facts in writing.

Permanent establishment (PE) is the concept in double tax treaties that decides when a company based in one country becomes taxable in another. It sits in Article 5 of the UK–Spain Double Taxation Convention.
If your working from Spain were held to create a PE for your UK employer, the consequences for them are serious and not merely administrative:
That is why a company that is entirely relaxed about remote work in general can still stall on Spain specifically. It is not obstruction. It is a real risk with a real number attached, and nobody in HR is equipped to price it.
The leading Spanish authority is binding tax ruling V0066-22, issued by the Dirección General de Tributos on 18 January 2022. It considered exactly this fact pattern — an employee of a foreign company working remotely from their home in Spain — and held that no permanent establishment arose.
Four facts carried that conclusion:
Read together, those facts mean the company had neither a fixed place of business at its disposal in Spain nor a dependent agent habitually concluding contracts there — the two routes by which a PE normally arises.
Because the ruling turns on facts, the risk is highest where the facts run the other way. Watch for:
| Amplifier | Why it raises risk |
|---|---|
| Seniority with sales authority | An employee who can bind the company looks like a dependent agent, which is an independent route to PE regardless of premises |
| Employer-paid Spanish premises or allowances | Funding a desk, an office or a co-working membership in Spain suggests a place of business at the company’s disposal |
| Customer-facing roles negotiating in Spain | Negotiation on Spanish soil is close to the conduct the dependent-agent test is aimed at |
| Spanish bank accounts in the company name | A visible commercial footprint in Spain, in the company’s own name |
| The company directed the move | Undoes the first and most important V0066-22 fact — that relocation was the employee’s choice |
Note how many of these are avoidable by design rather than by argument. Not taking a company-funded desk in Madrid is cheaper than defending a PE position later.
Being on the right side of V0066-22 is not much use if nobody wrote it down. The place to record it is the remote-work addendum to your employment contract — a short side-letter that sits alongside the employer letter in your visa file and in the company’s records.
The addendum should state explicitly that:
This does double duty. It is the evidence supporting the tax position, and it is the document that lets your employer say yes with something on file rather than on trust. The pack’s employer-letter template already carries this fact pattern as section 5, with the Rome I working-time clauses as section 6, worded so HR can lift them into a contract side-letter.
The conversation goes better when you separate the three things employers tend to fuse into one worry.
Two honest caveats. First, V0066-22 is a ruling on a set of facts, and your facts may differ in ways that matter — particularly if you are senior, client-facing, or if the company has any existing Spanish presence. Second, PE is only one of the tax questions raised by the move; your own Spanish tax position is a separate matter, and largely turns on whether you opt into the Beckham Law within the six-month Form 149 deadline.
If the amounts involved are significant, or if any of the amplifiers above apply to you, your employer should take Spanish corporate tax advice rather than rely on a web page. What this page is for is having an informed conversation, and knowing which document resolves which worry.
Next: the employer letter and addendum, or your own tax position under Beckham.
On the facts of binding ruling V0066-22, no. The Direccion General de Tributos held on 18 January 2022 that no permanent establishment arose where the employee relocated unilaterally, the company kept its UK office, the employer paid no allowance for Spanish premises, and the employee had no authority to conclude contracts. Risk rises where those facts are reversed.
It is a binding Spanish tax ruling (consulta vinculante) issued by the Direccion General de Tributos on 18 January 2022, dealing with an employee of a foreign company working remotely from home in Spain. It found no permanent establishment arose. Being binding, it constrains the Spanish tax administration in cases with the same facts.
Spanish corporate income tax at roughly 25% on the profits attributable to the establishment, plus full Spanish corporate tax registration and compliance obligations and the professional fees that go with them. Exposure can be retrospective if the position is challenged later.
Seniority with authority to conclude contracts, employer-paid Spanish premises or workspace allowances, customer-facing roles where negotiations happen in Spain, Spanish bank accounts in the company name, and the company having directed the relocation rather than the employee having requested it.
Through a remote-work addendum to your employment contract stating that you requested the relocation, that the company maintains an alternative UK workspace, that you have no authority to conclude contracts in Spain, that the employer pays no allowance for your Spanish workspace, and that no Spanish premises or company bank accounts exist.
If the amounts are significant, or if you are senior, client-facing, or the company already has any Spanish presence, yes. V0066-22 is a ruling on a particular set of facts, and differences in your facts can matter. This information is not a substitute for Spanish corporate tax advice.
