Renouncing Spanish citizenship is possible. But before doing so, you need to be very clear that it’s a decision with legal and tax consequences that are not always immediately reversible, and that in many cases there is an alternative most people are unaware of at the exact moment they need it most: dual citizenship.
This article explains exactly what renunciation involves, who genuinely needs it, how the process works, what tax obligations remain, and what options exist to recover Spanish citizenship if the decision is made and later reconsidered.
When Does Renouncing Spanish Citizenship Make Sense?
The honest answer is: in fewer cases than you might think. Most people asking this question do so because the country where they want to naturalize requires them to renounce their Spanish citizenship as a condition for granting theirs. That’s the most common scenario.
But there’s a lot of nuance here, because the picture changes significantly depending on the destination country:
| Destination Country | Requires Renouncing Spanish Citizenship? | Notes |
|---|---|---|
| Austria | Yes, except in very limited cases | One of the most restrictive nationality laws in Europe |
| Netherlands | Yes, in most cases | Exceptions exist for birth, inability to renounce, or marriage to a Dutch national |
| Japan | Yes | Requires choosing one citizenship before age 22 if both were held from birth |
| China | Yes, automatically | Does not recognize dual citizenship under any circumstances |
| Germany | No (since June 2024) | 2024 reform allows multiple citizenship without prior renunciation |
| France | No | Bilateral agreement between Spain and France since 2021 |
| United States | No | Only loses U.S. citizenship someone who acquires another with the express intent to renounce |
| United Kingdom | No | Allows dual citizenship; renunciation before Spanish authorities has no effect in the UK |
The first step, before considering any renunciation, is to verify whether your destination country actually requires it and whether a dual citizenship route already exists. To understand what options are available depending on your situation, our guide on dual Spanish citizenship covers all the current scenarios in detail.
There is also a second scenario, less common but real: people who want to renounce for personal, ideological, or estate planning reasons. In those cases the process is the same, but the tax implications deserve very careful analysis beforehand.
The Renunciation Process: Where and How It’s Filed
Express renunciation of Spanish citizenship is governed by Article 24.2 of the Civil Code, which states the following:
“In all cases, Spanish nationals who are emancipated and expressly renounce their citizenship shall lose it, provided they hold another citizenship and habitually reside abroad.”
Three conditions are cumulative and non-negotiable. The person must be of legal age or emancipated. They must hold another citizenship at the time of renunciation. And they must habitually reside abroad. If all three are not met simultaneously, the renunciation has no legal effect.
The procedure is carried out through an express declaration before the officer of the consular Civil Registry with jurisdiction in the applicant’s country of residence. It is not processed before a Spanish notary or before the Civil Registry in Spain. It is a personal act that cannot be delegated to a representative, and the standard documentation includes:
- Valid or expired Spanish passport proving Spanish citizenship
- Identity document from the other citizenship held
- Documentation proving habitual residence abroad (residence certificate from the destination country or equivalent)
- At some consulates: a specific renunciation declaration form
Once the renunciation is formalized and recorded in the Civil Registry, the loss of Spanish citizenship is registered. From that point on, the person ceases to be a Spanish citizen for all legal purposes.
The procedure is free. No administrative fees apply.

A Key Distinction: Renunciation Before Spain Is Not Binding on Other Countries
This point causes frequent confusion and has real practical consequences. A renunciation filed before Spanish authorities is a declaratory act under Spanish law. It does not automatically result in loss of citizenship in the renouncing party’s country of origin if that country does not recognize it.
Morocco, for example, does not recognize unilateral renunciation of Moroccan citizenship. A Moroccan citizen who renounces Spanish citizenship before the consulate remains Moroccan in the eyes of their country. The effect of the declaration is confined to the Spanish legal system.
The reverse also occurs: many Spaniards who naturalize in countries like the United States or the United Kingdom formally declare before the Spanish Civil Registry that they renounce their Spanish citizenship as a procedural requirement for acquiring the other. But that declaratory act does not necessarily result in the actual loss of the other citizenship under that country’s law, especially if that country neither requires nor recognizes such a unilateral renunciation.
The practical conclusion: before renouncing, it is essential to analyze both the Spanish Civil Code and the nationality law of the destination country at the same time.
Tax Consequences: Exit Tax and Pending Obligations
This is the section most frequently overlooked, and where the surprises can be most costly. There are two separate tax dimensions to consider.
1. Renouncing citizenship is not the same as losing tax residency. These are two distinct concepts. The Spanish Tax Agency considers anyone who spends more than 183 days per year in Spain, or who has their main economic or family interests here, to be a tax resident, regardless of their nationality. Renouncing Spanish citizenship does not automatically cancel tax obligations in Spain if the center of your life remains here.
2. The exit tax, governed by Article 95 bis of the Personal Income Tax Law (IRPF). This tax applies to unrealized capital gains on shares in entities when a taxpayer loses their tax residency in Spain. It is not triggered by renouncing citizenship, but by a change of tax residency. It applies exclusively to those who meet both of the following filters: having been a tax resident in Spain for at least 10 of the 15 years prior to the change, and holding shares whose market value exceeds 4 million euros (or at least a 25% stake in an entity worth more than 1 million euros).
For most people, the exit tax does not apply. But for those with significant business assets, it can represent a substantial tax bill before the transition is complete. If this applies to you, prior planning is essential. Our articles on Spanish taxes for foreigners and personal tax optimization in Spain provide useful context, and our tax planning in Spain service can help you structure the transition with the lowest possible impact.
There are also pending obligations that do not disappear with the renunciation of citizenship: prior tax debts, unfiled income tax returns, real estate in Spain subject to the Non-Resident Income Tax (IRNR) once tax residency is lost. Renouncing citizenship without having regularized the prior tax situation can lead to later claims with surcharges.

Can You Recover Spanish Citizenship After Renouncing It?
Yes, but with conditions. Article 26 of the Civil Code governs the recovery of Spanish citizenship for those who have lost it. The path is the same as for any other cause of loss: legal residency in Spain (unless you are an emigrant or child of an emigrant, in which case you can process it from the consulate), a formal declaration before the Civil Registry, and subsequent registration.
There is an important distinction in the case of voluntary renunciation: if the loss occurred under the causes in Article 24 of the Civil Code (including express renunciation), the recovery process is direct. It does not require prior Government authorization, unlike those who lost citizenship under the sanctioning causes of Article 25. The recovery process is explained in detail in our guide on how to recover lost Spanish citizenship.
What is worth anticipating is that recovery is not immediate. It involves a file with its own timelines, and during that period the person does not hold Spanish citizenship. If the renunciation was made to obtain another and is later reconsidered, the path back requires time and, in most cases, legal residency in Spain.
The Alternative Worth Considering First: Dual Citizenship
For many of the profiles that arrive at this search, dual citizenship is a real option that has not been fully evaluated. Spain allows you to retain Spanish citizenship simultaneously with that of another country in a significant number of situations: nationals of Latin American countries, Portugal, Andorra, the Philippines, Equatorial Guinea, and, since 2021, France.
Outside these explicit agreements, the situation is more complex but not necessarily impossible. As discussed above, renunciation of the previous citizenship declared before the Spanish Civil Registry has effects limited to the Spanish legal system and does not automatically result in the loss of the other citizenship if the corresponding country does not recognize it. This creates, in practice, de facto dual citizenship situations not formally covered by any treaty.
If you’re at this point and haven’t yet made any decision, the most efficient step is a prior analysis of your specific situation. The right decision depends on your country of origin, your destination country, your assets, and your tax obligations in each jurisdiction.

Frequently Asked Questions: Renouncing Spanish Citizenship
Can I renounce Spanish citizenship if I live in Spain?
No. Article 24.2 of the Civil Code requires the person renouncing to habitually reside abroad at the time of the declaration. Someone residing in Spain cannot formalize the renunciation. Additionally, the person must be of legal age or emancipated and must simultaneously hold another citizenship. If all three conditions are not met, the renunciation has no legal effect.
Does renouncing Spanish citizenship mean I no longer have to pay taxes in Spain?
Not automatically. Tax obligations in Spain depend on tax residency, not citizenship. If you continue living in Spain or have your main economic interests here, you will remain an income tax (IRPF) contributor regardless of your nationality. Renouncing Spanish citizenship without also changing your tax residency produces no relevant tax effect.
Does renouncing Spanish citizenship before the consulate mean I also lose my other citizenship?
No. A renunciation filed before Spanish authorities is an act of Spanish law with effects within the Spanish legal system. It does not result in loss of the other citizenship unless the corresponding country expressly recognizes it. Countries such as Morocco, the United States, or the United Kingdom do not recognize a unilateral renunciation made before a Spanish consulate, so in practice the person may retain both.
Is it possible to recover Spanish citizenship after renouncing it voluntarily?
Yes. Recovery is governed by Article 26 of the Civil Code. Someone who renounced voluntarily can recover citizenship without needing prior Government authorization, unlike those who lost it for sanctioning reasons. The requirements are: legal residency in Spain (except for emigrants and their children, who can process it from the consulate), a formal declaration of intent to recover it before the Civil Registry, and registration of the recovery.
What is the difference between express renunciation and automatic loss of Spanish citizenship?
Express renunciation is a voluntary, deliberate act: the person appears before the consular Civil Registry and formally declares that they renounce Spanish citizenship. Automatic loss (also governed by Article 24 CC) occurs without any express act when an emancipated Spanish national residing abroad acquires another citizenship and three years pass without having declared their intention to retain Spanish citizenship. They are different mechanisms with the same outcome: loss of citizenship.
