The NIE Number for Spanish Inheritances: How Every Foreign Heir Obtains a Spanish Tax ID
Every foreign heir of a Spanish estate needs an NIE — the Número de Identificación de Extranjero, the Spanish tax identification number for non-nationals. Without it the inheritance tax return cannot be filed, the notarial deed of acceptance cannot be registered, and the bank cannot release the deceased’s funds. The NIE is administrative, not migratory: it does not give the heir the right to live or work in Spain, only the ability to interact with the Spanish tax and registry systems. It is, however, mandatory, and obtaining it is one of the first practical steps in any international inheritance file. This article explains who needs an NIE, the three main routes to obtain one (consular application, in-Spain application, or application through a power of attorney), the documents required for each route, the typical timeline and cost, and the common errors that cause applications to be rejected. We also cover the relationship between the NIE and the heir’s home-country tax residence, the steps to keep the NIE current if the heir later sells the property or receives ongoing rental income, and the value of using a dedicated inheritance lawyer in Spain to coordinate the NIE application with the rest of the inheritance file.
What the NIE is and why every heir needs one
The NIE is a unique identifier assigned by the Spanish Ministry of the Interior to every foreign national who has any economic, professional or social interest in Spain. It takes the form of a letter, seven digits and a check letter — for example, Y1234567Z. The NIE is the equivalent of the Spanish DNI for foreigners and is the indispensable key to interacting with Spanish authorities, banks, registries and notaries. For an heir, the NIE is required to file inheritance tax, to be named in the notarial deed of acceptance, and to appear in the Land Registry as the new owner of any inherited property.
A common misunderstanding is that the NIE is a residence document. It is not. The NIE is purely an identification number; it confers no right to enter, live, or work in Spain. A British heir living in London who inherits a Spanish flat needs an NIE to register the inheritance, but the NIE does not change his immigration status. Conversely, an EU national exercising free-movement rights in Spain is given an NIE as part of the registration certificate (Certificado de Registro de Ciudadano de la Unión), but the two documents are administratively distinct.
Who needs an NIE and when
Every individual heir named in the notarial deed of acceptance needs their own NIE. There is no exception for minors — a child who inherits a share of a Spanish property must have an NIE in their name, obtained through their legal representative. There is no exception for distant heirs who will renounce — even an heir who plans to walk away from the estate must have an NIE if the renunciation is to be made by notarial deed in Spain (the NIE is required for any signature before a Spanish notary).
The NIE is needed before the notarial appointment, not at it. A common scheduling error is to book the notary for week ten and start the NIE application in week eight, only to discover that consular appointment times have stretched to twelve weeks. The NIE application should be the first thing started after the death certificate is obtained — typically in week one of the file. We deal with NIE applications as part of our standard inheritance services.
Route one: applying at a Spanish consulate abroad
For heirs living abroad, the easiest route is to apply at the nearest Spanish consulate. The application is made in person, with the original passport, two recent passport photographs, a completed EX-15 form (or the consulate-specific form), and a written reason for the application — in an inheritance case, a copy of the death certificate and a brief statement that the applicant is an heir of the deceased, together with the deceased’s details and the location of the Spanish assets, is sufficient. The consular fee is around €10.
The bottleneck is appointment availability. The Spanish consulate in London typically runs an eight to twelve week wait for NIE appointments. New York is similar. Manchester and Edinburgh can be faster but vary. Smaller consulates (Birmingham, Bristol) are often the fastest because demand is lower. The practical advice is to check appointment availability across all the consulates within reasonable travelling distance and book the first available slot. The actual appointment is short — typically fifteen minutes — and the NIE is normally issued on the spot or within one to two weeks by post.
Route two: applying in Spain in person
An heir travelling to Spain can apply for the NIE in person at any police station with a Foreigners Office (Oficina de Extranjería) or at the central immigration office (Comisaría General de Extranjería y Fronteras) in Madrid. The application is made on the same EX-15 form, with the same documents (passport, two photographs, evidence of the reason for the application), and a small fee (around €10) payable at any Spanish bank using Model 790-012.
Appointment availability in Spain has been a recurring problem for years. The online appointment system (Cita Previa) often shows no availability in major cities for weeks at a time. The Madrid and Barcelona offices are usually the most heavily booked; smaller provincial offices are sometimes much faster. For an heir who has flown to Spain specifically to handle the inheritance, the inability to book an NIE appointment can be a serious problem. The work-around is to book the appointment well in advance of the trip — typically four to eight weeks before — or to delegate the application to a lawyer under a power of attorney.
Route three: applying through a power of attorney
The most efficient route for a foreign heir who cannot easily reach a consulate or travel to Spain is to delegate the NIE application to a Spanish lawyer under a power of attorney. The power must specifically authorise the lawyer to apply for an NIE on the heir’s behalf — a generic inheritance power is not enough. With the special power, the lawyer files the application at a Spanish police station in the lawyer’s home city and the NIE is issued within two to four weeks. The cost is the consulate fee plus the lawyer’s fee, typically €200 to €400 in total. The drafting of the power and the practical mechanics are covered in our article on the Spanish inheritance power of attorney.
This route is the standard for files we handle. It removes the bottleneck of consular appointments and allows the NIE to be in hand within four to six weeks of instruction, in parallel with the apostille and translation of the other inheritance documents. It is the fastest and most reliable route in 90% of international files.
Documents required across all three routes
The standard document pack is: original passport (with a clear photocopy of the data page), two recent passport-format photographs (35 × 45 mm, white background), completed EX-15 form (or its consular equivalent), evidence of the reason for the NIE (copy of the deceased’s death certificate, a brief statement of heirship, and a description of the Spanish asset that triggers the application), and proof of payment of the Model 790-012 fee. For applications through a power of attorney, the lawyer adds the original power and a copy.
Children under fourteen do not need photographs but must have their identity documented by the foreign equivalent of a passport or by a birth certificate apostilled and translated. The legal representative of a minor (usually the parent) must sign the application and produce their own NIE or DNI. Where both parents are abroad and one has died, additional documentary requirements (apostilled and translated parental authority documents) may apply.
Typical timeline and cost
The consular route, where appointments are available within four weeks, produces an NIE within five to eight weeks of starting the process. The lawyer-and-power-of-attorney route in Spain produces an NIE within four to six weeks. The in-person Spain route depends entirely on appointment availability and ranges from two weeks (in the best case) to four months (in the worst case). The total cost ranges from €10 (in-person consular application) to €400 (lawyer-delegated application including the power of attorney).
For an inheritance file with a six-month tax deadline, an NIE timeline of more than eight weeks is a problem. The longer the NIE takes, the less time remains to apostille and translate the other documents, draft the deed of acceptance, file the inheritance tax return and pay it. The recommended approach is therefore to start the NIE application as the first administrative step in the file, in parallel with the request for the death certificate. Files where the NIE application is left until month four or five almost always end up requesting the six-month extension.
Common errors and rejections
The most common reason for an NIE application to be rejected is an inadequate statement of the reason. A heir who simply writes “I am inheriting a property in Spain” without specifying the deceased, the asset and the relationship will see the application returned for further information. The statement should name the deceased, give the date of death, identify the asset (with the cadastral reference for a property, or the bank and account for a bank account), state the applicant’s relationship to the deceased, and reference the death certificate and the will (or the certificate of last will if no will exists).
Other recurring errors include using an out-of-date EX-15 form (the form is occasionally revised; the latest version is always on the Ministry of the Interior website), using photographs that do not meet the format requirements, and failing to pay the Model 790-012 fee at a Spanish bank before the appointment. None of these errors are difficult to fix but each adds a week or more to the timeline.
After the NIE: keeping it usable for the future
The NIE is permanent — it does not expire — but the supporting documentation (the certificate of assignment) may become outdated, particularly the address recorded with the Spanish authorities. If the heir later sells the inherited property, opens a Spanish bank account, or receives ongoing rental income from a Spanish property, the address recorded against the NIE should be updated to the current contact address. The update is made on Model EX-15 at any Foreigners Office or consulate. An out-of-date address is the most common cause of correspondence from the Spanish tax authority going unanswered, which in turn is the most common cause of unexpected tax-inspection procedures against non-resident heirs.
For heirs who will retain Spanish assets after the inheritance — most typically a Spanish bank account or a Spanish property held as a holiday home — the NIE remains the central administrative identifier for the rest of their interaction with Spain. Annual non-resident income tax (IRNR) is filed under the NIE; community fees, property tax (IBI) and utilities are billed against the NIE. Keeping the NIE active and the address current is a small ongoing task that prevents larger problems later.
