NIE Number for Spanish Inheritance

Every Heir Needs a NIE

The Número de Identidad de Extranjero (NIE) is Spain's foreigner identification number. For a Spanish inheritance, every heir must obtain one to access applicable regional inheritance-tax reductions.

For the inheritance process, the NIE is especially important for:

• Accessing applicable regional inheritance-tax reductions
• Avoiding delay against the six-month Spanish inheritance-tax deadline

If a German family member dies in Spain and leaves any assets — a bank account, real estate, a vehicle, life insurance — every heir named in the will or entitled by law should start the NIE application promptly rather than wait for the estate to be settled.

How to Apply from Germany

German residents can apply for a NIE through a Spanish consulate in Germany. The consulates in Berlin, Munich, Hamburg, Frankfurt, Düsseldorf, and Stuttgart all process NIE applications.

What you'll need:

• EX-15 form — the standard NIE application form, available from the consulate or downloadable from Spain's public administration portal
• Valid passport and a photocopy
• Proof of reason — a letter or document explaining why you need the NIE (the death certificate and will, or a letter from a Spanish notary or attorney stating you are an heir to a Spanish estate)
• Consulate fee — confirm the current amount with the consulate before applying

Some consulates require an appointment booked weeks in advance. Processing can take several weeks or months. During peak periods or at high-demand consulates, it can take longer.

The Deadline Collision

Here's where the NIE becomes an urgent problem rather than a routine formality: Spain's inheritance tax must be filed within six months of the date of death. Heirs can request a one-time six-month extension, but that request itself must be filed within the first five months.

If you start the NIE application in month three and it takes two months to process, you'll receive it in month five — leaving almost no time to gather the remaining documents, calculate the tax, and file. A late NIE application can leave little time to meet the filing or extension deadline; a missed deadline triggers automatic surcharges of 5% to 20%.

Start the NIE application as soon as you learn you may inherit Spanish assets. Don't wait until you have all other documents assembled.

Alternatives: NIE via a Representative in Spain

If you cannot visit a Spanish consulate or the wait time is too long, a Spanish attorney can apply for a NIE on your behalf through a local police station (Comisaría de Policía) or foreigner's office (Oficina de Extranjeros) in Spain. This requires a notarized power of attorney (poder notarial) authorizing the attorney to act for you.

This route requires finding and engaging a Spanish attorney, which adds cost. Confirm the current procedure and processing time with the attorney and the relevant office before relying on it to meet a tax deadline.

One NIE per Person, for Life

Once issued, your NIE number is permanent. If you already have one from a previous property purchase, work period, or tax filing in Spain, you do not need a new one — use the existing number. Check old documents or ask the consulate to verify if one was previously assigned.
