Argentina Dual Citizenship: Rules, Taxes & Investor Guide (2026)

Does Argentina allow dual citizenship?

Yes. Argentine law does not require you to renounce your existing nationality when you naturalise as Argentine, so you can hold both passports at the same time. Your country of origin may apply its own rules on dual nationality, so it is worth confirming your home country's position before you proceed.

Growing Interest in Argentina’s Dual Citizenship Rules

With the introduction of Argentina's Citizenship by Investment program under DNU 366/2025 and Decree 524/2025, international investors are taking a closer look at how Argentina treats dual nationality and tax residency. For answers to the most common investor questions including dual citizenship, family inclusion, and tax implications, see our Complete Argentina CBI FAQ (2026).

For investors seeking flexibility, Argentina stands out for its liberal stance on dual citizenship and its clear distinction between citizenship and tax residency. These factors together make the country's Citizenship by Investment framework, once operational, uniquely attractive for global entrepreneurs, high-net-worth individuals, and mobile investors planning for long-term global mobility.

Argentina’s Constitutional Stance on Dual Nationality

Argentina is one of the few Latin American countries whose constitution and nationality laws fully recognize dual citizenship. This means that new citizens are not required to renounce their existing nationality when obtaining an Argentine passport.

The right to hold multiple nationalities has been reinforced by both the Nationality Law and Supreme Court jurisprudence, ensuring that Argentine citizens, whether by birth, naturalization, or investment, retain their original citizenship without restriction.

This approach aligns with Argentina’s international agreements with countries such as Italy, Spain, and Chile, where dual nationality is formally recognized. Even for citizens of non-treaty states, Argentina’s domestic law remains permissive, meaning no renunciation is required during the naturalization or future Citizenship by Investment process.

Implications for Foreign Investors

For international investors, this legal clarity is significant. Dual citizenship recognition simplifies the process of integrating Argentina’s new investment route with existing passports or citizenships.

It also means that investors who acquire Argentine citizenship through the program, once it is operational, would enjoy the benefits listed below. Note that while Argentina imposes no restrictions on dual citizenship, your home country's rules may vary. Most jurisdictions permit dual nationality, but you should verify your specific situation before applying.

• Uninterrupted global mobility, since they can retain their existing passports.
• Expanded access to regional markets, as Argentine citizens benefit from Mercosur freedom of movement across South America.
• Family continuity, since spouses and dependents can also be included under one family application.

Combined with a framework designed to require no prior residency, these features make Argentina's program convenient for global investors once it opens.

Tax Residency and Global Income Rules

One of the most appealing aspects of Argentine citizenship for investors is the country’s taxation principle based on residency, not citizenship.

This means that Argentine citizens who do not reside in Argentina are generally not taxed on foreign-sourced income. This distinction is crucial for internationally mobile investors managing income, dividends, or capital gains abroad.

How Argentina Defines Tax Residency

An individual is considered a tax resident in Argentina if they:

• Spend more than 183 days per year in the country, or
• Have their center of vital interests (economic, professional, or familial ties) located in Argentina.

Foreigners who become Argentine citizens but continue to reside abroad will typically not be deemed tax residents, as long as their primary income and personal base remain outside Argentina.

Argentina also has an expanding network of double-taxation treaties, reducing exposure for those who do hold business interests within the country.

Expected Treatment for Citizenship by Investment Participants

Argentina's tax exemption framework for CBI investors has been formally addressed under Law No. 27802, which provides specific protections for qualifying foreign investors. Citizenship obtained through investment does not by itself trigger tax residency or create new reporting obligations for non-residents. CBI participants are treated the same as any other Argentine citizen in terms of tax obligations, meaning taxation is based on residency, not on how citizenship was acquired. For a full breakdown of the investor tax exemption provisions, see our Argentina CBI tax exemption guide.

Treatment of Dual Citizens Under Decree 524/2025

DNU 366/2025 formally amended Argentina's nationality laws to allow direct acquisition of citizenship through investment without prior residency, and Decree 524/2025 built the program's administrative framework on top of that change. DNU 366/2025 was declared invalid by two federal courts in June 2026 and is now before the Supreme Court on the government's appeal. Decree 524/2025 itself remains formally in force. This does not change how dual nationality is treated, which is addressed below.

Dual citizens, whether by birth, descent, or investment, retain the same constitutional rights and responsibilities as any other Argentine national. They can:

• Vote and hold property in Argentina.
• Open local and international bank accounts as Argentine citizens.
• Enjoy consular protection from Argentina abroad.

Importantly, dual nationality does not limit rights or privileges, nor does it affect inheritance or property ownership under Argentine civil law. Investors who obtain citizenship through this new framework will therefore enjoy full constitutional parity.

Legal Considerations for Investors

While Argentina’s dual-citizenship policy is clear, investors should remain mindful of their home country’s stance on multiple citizenships. Some nations restrict or penalize the acquisition of a second nationality, while others allow it freely.

Additionally, global investors should ensure compliance with:

• International tax-reporting requirements (such as FATCA or CRS).
• Source-of-funds documentation to meet Argentina's due-diligence standards.
• Investment verification once Argentina's implementing regulation is published.

Investors preparing in advance by consolidating financial documentation and establishing compliance with global standards will be best positioned for a smooth application once the Argentina Citizenship by Investment program officially opens.

Treatment of Family Members

Dual citizenship in Argentina extends smoothly to family applications. Under the Ministry of Economy's announcement of 2 October 2026, a main applicant can include a spouse and children, each with an additional contribution: USD 100,000 for a spouse or an unmarried, childless child aged 18 to 25, and USD 25,000 for each child under 18. These figures are not yet codified in regulation.

This structure ensures family unity while maintaining Argentina’s constitutional commitment to equal citizenship rights. Once naturalized or approved through investment, dependents will hold the same nationality status and legal protections as the principal investor.

Conclusion: Clarity, Flexibility, and Global Opportunity

Argentina’s approach to dual citizenship combines constitutional openness with modern investment mobility. By allowing multiple nationalities and defining taxation based on residency rather than citizenship, it provides international investors with flexibility rarely found in other jurisdictions.

Argentina's tax framework for CBI investors is now formally confirmed under Law No. 27802, providing legal clarity that foreign investors obtaining citizenship through the Argentina Citizenship by Investment program would enjoy the same rights and tax obligations as any other Argentine national, with taxation based on residency, not citizenship.

As global citizenship options narrow across Europe and the Caribbean, Argentina's combination of legal transparency, economic reform, and global credibility positions it as one of the most promising destinations for forward-looking investors, once the program's legal foundation is settled.
