NIE for buying property in Spain: get it before the deposit contract

01What the NIE is — and what it is not

The NIE (Número de Identidad de Extranjero) is Spain’s identification number for foreigners. Under art. 206 of Royal Decree 557/2011 (RD 557/2011) it is assigned to foreigners who relate to Spain through their “economic, professional or social interests” — and buying property is the textbook economic interest. You do not need to live in Spain, plan to move there or hold any visa: the number identifies you before Spanish authorities, nothing more.

The second half of the definition matters just as much. The NIE grants no residence rights whatsoever — it is not a permit, not a visa, not a step towards either. And the reverse is also true: you do not need any “residency” to get it. A buyer who spends two weeks a year in Spain has exactly the same right to a NIE as one who is relocating.

One feature saves paperwork later: the number itself never expires. Once assigned, it is yours for life. What some banks and offices ask for in practice is a recently issued NIE certificate — often no older than about three months. That is a habit of practice, not a legal expiry of the number, and re-issuing the certificate is a far smaller task than the first application.

02Where the purchase actually needs it

In a property purchase the NIE doubles as your tax identification. The notary will not authorise the deed (escritura) without it, and every tax filing around the purchase runs on it: the transfer tax on resale property or the VAT-plus-stamp-duty forms on new builds (ITP or IVA/AJD), later the annual municipal property tax (IBI) and — for non-resident owners — the modelo 210 income-tax return. No NIE, no completion and no compliant tax file.

Here is the timing nuance most buyers discover too late: the deposit contract (contrato de arras) can be signed on a passport alone. Nothing stops you fixing the deal before the NIE exists. But the completion deadline written into that contract must leave enough time to obtain the number — a hard date with no NIE margin is one of the classic ways foreign buyers end up losing a deposit. How that deadline should be drafted is covered in our arras contract guide.

03Route 1: apply in person in Spain

If you are in Spain — even on a short buying trip — you apply at the designated national police station or the immigration office (Oficina de Extranjería) for the province. You need an appointment booked in advance (cita previa) through the official online system, and in busy provinces the free slots, not the paperwork, are the real bottleneck. Start hunting for an appointment as early as the trip is booked.

What you bring to the appointment:

• Form EX-15 — the standard NIE application filed at your own request (a instancia del interesado), completed and signed.
• Fee form 790, code 012 — the fee is paid at a bank before the appointment; ≈€10, check the current figure printed on the 790-012 form itself, as the amount is updated administratively.
• Passport — original plus a copy.
• Proof of the economic interest — for a purchase, typically the arras or reservation contract, or another document showing the transaction you are entering.

04Route 2: the Spanish consulate where you live

If you are not travelling to Spain soon, you can file the same application at the Spanish consulate serving your place of residence. The file is identical — form EX-15, the 790-012 fee, your passport and the document proving your interest — and the consulate forwards the application to Spain for the number to be assigned.

That forwarding step is why the consular route is usually the slowest of the three: in practice anywhere from days to a few weeks, depending on the consulate and the season. None of that is a statutory deadline — it is simply how the pipeline behaves — so treat consular timing as a planning input, not a promise, and build the purchase calendar around it.

The consular route suits buyers who are early in the process: you started before signing anything, the weeks of forwarding cost you nothing, and you land in Spain for completion with the number already assigned.

05Route 3: a representative in Spain with a power of attorney

You do not have to appear anywhere in person at all. A representative in Spain — your lawyer, an administrative agent (gestor) or a person you trust — can apply for the NIE on your behalf, provided they hold a notarial power of attorney (poder) that expressly covers the NIE application. A vague general text is not enough for Spanish practice: the faculty to request the NIE should be spelled out.

The poder can be granted before a Spanish notary, at a Spanish consulate (consuls exercise notarial functions), or before a notary in your own country with an apostille and a sworn translation into Spanish. If you are buying remotely you will very likely need a poder for the purchase itself anyway — so have the NIE faculty written into the same document from the start. How to draft one that a Spanish notary will accept is covered in our power-of-attorney guide.

For buyers on a tight completion deadline this is often the fastest realistic route: your representative fights the appointment system and stands in the queue while you stay home.

06Timing strategy — and the classic mistakes

The whole strategy fits in one sentence: start the NIE the moment the purchase becomes serious, and never sign an arras deadline that ignores it. These are the mistakes that actually cost buyers money and weeks:

• Starting after the arras, with a tight completion date. The deposit contract binds you to a calendar; the NIE queue does not care about your calendar. If the appointment or the consular forwarding runs long, you are negotiating an extension from a weak position — or risking the deposit.
• Confusing the NIE with residence. EU citizens who stay in Spain longer than three months register for the certificado de registro — a different procedure with different requirements and a different document. For buying property you need the NIE; neither document replaces the other, and no purchase requires you to become a resident.
• Waiting for the NIE to open a bank account. Practice varies between banks: some open a non-resident account on a passport and ask for the NIE later, others want the number upfront. Ask your chosen bank what it accepts instead of assuming — often you can run the account and the NIE in parallel and save weeks.
• Assuming the certificate lasts forever. The number does; the paper often does not, in the eyes of banks and some offices, which like a certificate no older than about three months (practice, not law). Time the certificate close to when you actually need it.
