Spain does allow triple citizenship in practice, even though its nationality law never uses that term. Whether you can hold a Spanish passport alongside two others depends on two things: whether one of your other nationalities comes from a country Spain has agreed to exempt from its renunciation rule, and whether the third country’s own law lets its citizens acquire foreign nationality without losing their status. Get both answers right and Spain has no objection to the number of passports in your drawer.
Spain’s Renunciation Rule and Why It Often Doesn’t Bite
Anyone becoming Spanish through residence, naturalization, or the option process must do three things: swear allegiance to the King and the Constitution, register the acquisition with Spain’s Civil Registry, and formally declare renunciation of any prior nationality.1Ministerio de Justicia. Spanish Civil Code – Article 23 On paper, this sounds like Spain forbids holding a second passport.
In reality, that renunciation is a declaration required by Spain, not an act that actually cancels the other citizenship. Spain’s Directorate General of Registries and Notaries clarified in a 1993 resolution that the acquisition of Spanish nationality cannot be made dependent on whether a foreign country treats the renunciation as effective. If the other country’s law says citizenship can only be lost through a specific process before its own authorities, a declaration made in front of a Spanish registrar has no legal effect there.
A British citizen who declares renunciation before a Spanish registrar keeps British citizenship, because losing it requires a separate process through the UK Home Office. The United States takes a similar position: a renunciation made to a foreign official does not cost you your U.S. nationality. That gap between what Spain asks for and what other countries recognize is what makes multiple citizenships workable for so many people.
The Countries Spain Exempts From Renunciation
The Spanish Constitution authorizes the government to negotiate dual nationality arrangements with Latin American countries and other nations sharing special ties with Spain.2Constitute Project. Spain 1978 (rev. 2011) Constitution – Section 11 Nationals of these countries do not need to renounce anything when they become Spanish, and Spaniards by birth who acquire one of these nationalities do not lose their Spanish citizenship either.3Ministerio de Justicia. Spanish Civil Code – Article 24
The exempt countries are:
- All Latin American nations: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, the Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, and Venezuela
- Andorra
- The Philippines
- Equatorial Guinea
- Portugal
- France, added through a bilateral agreement signed in March 2021 and in force since April 1, 20224La Moncloa. Nationality Agreement Between Spain and France Enters Into Force
Citizens of these countries also qualify for a shorter residency requirement when applying for Spanish citizenship: two years instead of the standard ten.5Ministerio de Justicia. Spanish Civil Code – Article 22
How Three Citizenships Fit Together
Spanish law contains no cap on the number of nationalities you can hold. What the Civil Code addresses is whether you must renounce a prior nationality when becoming Spanish, and under what circumstances you lose Spanish nationality later. Satisfy both, and a third passport is nothing Spain concerns itself with.
The cleanest path to holding three nationalities including Spanish looks like this. You already hold citizenship in one of Spain’s exempt countries. You acquire Spanish nationality without renouncing. You also hold, or later acquire, a third nationality from a country whose own law permits multiple citizenships. A common example is someone with both Argentine and Italian citizenship, which is a frequent combination given historic Italian migration to Argentina. Argentina is on Spain’s exempt list, and Italy does not strip citizenship for acquiring another. Add Spanish naturalization and the person holds three passports with no legal conflict.
The U.S. Department of State has confirmed that American citizens may hold more than two nationalities.6U.S. Department of State. Dual Nationality So a Colombian-American who naturalizes as Spanish ends up with all three: Colombia is exempt on Spain’s side, and the United States does not revoke citizenship for acquiring a foreign one.
The math is harder when your original country is not on Spain’s exempt list. A Chinese citizen who naturalizes as Spanish makes the formal renunciation declaration in Spain, and whether China actually strips its nationality is governed by Chinese law. If it does, you are left with only Spanish citizenship, and adding a third country later raises a different question, addressed below.
How a Third Passport Can Cost You the Spanish One
Acquiring an additional nationality after becoming Spanish can trigger loss of Spanish citizenship, and the rules differ depending on how you became Spanish in the first place.
If You Are Spanish by Birth
A Spaniard by birth who lives abroad and voluntarily acquires another nationality outside the exempt list loses Spanish citizenship after three years, unless within that window they formally declare their intent to keep it. Acquiring nationality from any Latin American country, Andorra, the Philippines, Equatorial Guinea, or Portugal does not trigger the clock at all.3Ministerio de Justicia. Spanish Civil Code – Article 24
Evidence that you have “used” your Spanish nationality during those three years also protects it. Renewing your Spanish passport, voting in Spanish elections from abroad, or using the passport for an official act such as marriage will count.
If You Are Naturalized
Naturalized Spaniards face a stricter version of the same idea. You lose Spanish nationality if you exclusively use the nationality you declared you were renouncing for a period of three years. Loss also follows from voluntary service in a foreign country’s armed forces or from holding public office there against Spain’s explicit prohibition. And a court can annul the citizenship within fifteen years if it was obtained through fraud or misrepresentation.7Ministerio de Justicia. Spanish Civil Code – Article 25
That first rule is the one triple-citizenship holders need to plan around. If you naturalized as Spanish after formally renouncing Colombian nationality (which Colombia did not actually strip), then spent three years living in Colombia using only your Colombian passport, Spain can treat your Spanish citizenship as lost. Naturalized citizens have to be deliberate about using Spanish nationality regularly.
Tax Reporting Follows You
Holding multiple passports creates overlapping reporting duties that surprise people every year.
Spanish tax residents with assets outside Spain worth more than €50,000 in any single category (bank accounts, securities, or real estate) must file a Modelo 720 declaration by March 31 each year. The original penalty regime was struck down by the European Court of Justice in January 2022 as disproportionate. Fines are now €20 per missing item, with a minimum of €300 and a maximum of €20,000, and the standard four-year statute of limitations applies.
If one of your citizenships is American, the United States requires you to report foreign bank accounts whose combined value exceeds $10,000 at any point in the year, even if you live entirely outside the U.S. and earn no U.S.-source income.6U.S. Department of State. Dual Nationality The U.S. also requires citizens to enter and leave on a U.S. passport regardless of what else they carry. Penalties for missed foreign account reports can reach tens of thousands of dollars per violation, with steeper consequences for willful failures.
Three Scenarios That Show the Pattern
A Mexican citizen who also holds French nationality moves to Spain and naturalizes after two years of residence. Mexico is exempt, France has been exempt since 2022, and no renunciation is required for either. Three citizenships, no friction from Spain.
A U.S.-born child of a Peruvian parent holds American and Peruvian citizenship from birth, then moves to Spain and naturalizes. Peru is on Spain’s exempt list, so Peruvian nationality is protected. The renunciation declared before the Spanish registrar has no effect on U.S. citizenship because the United States does not recognize renunciations made to foreign officials. Three citizenships in practice.
A German citizen naturalizes as Spanish and formally renounces German nationality before the Spanish registrar. German law causes loss of citizenship when a national voluntarily acquires another, unless they obtained a retention permit (Beibehaltungsgenehmigung) beforehand. Without that permit, the German nationality is genuinely gone and only Spanish citizenship remains. The formal renunciation and the foreign law lined up to the same result, and advance planning would have been the only way to change the outcome.
Spain’s own rules are one piece of the puzzle. Whether triple citizenship works for you depends just as much on what your other two countries do when you become Spanish, and on whether their laws treat that Spanish renunciation declaration as meaningful.
