Is it advisable to acquire a second citizenship? Legal, tax and property implications

Acquiring a second citizenship is a far-reaching decision that goes beyond mere immigration. It involves legal, tax, and property consequences that must be assessed holistically.

Frequent motivations

• Greater international mobility: visa-free access to more countries

• A backup plan for your assets in the event of political or economic instability.

• Access to labor markets in other blocs (especially the EU)

• Succession planning and intergenerational transmission

• Tax optimization combined with change of residence

• Diversification of personal and property risks

Does Argentina allow dual citizenship?

Yes, without restrictions. An Argentine citizen can acquire another citizenship without losing their Argentine citizenship, and a foreigner who becomes a naturalized Argentine citizen is not required to renounce their original citizenship.

Not all countries have the same system. Before starting a naturalization process, verify whether the applicant's country of origin allows dual citizenship, as some require renunciation of previous citizenship.

The fiscal dimension: the most sensitive point

Tax residency —not citizenship— is generally the determining factor for tax obligations. An important exception: the United States taxes its citizens on worldwide income regardless of their place of residence. Many naturalization processes require actual residence, which can unintentionally create a new tax residency with tax consequences that must be anticipated.

Patrimonial dimension

• Estate planning: some countries tax inheritance differently depending on citizenship

• Opening bank accounts and investments in certain jurisdictions

• Access to markets regulated by the investor's citizenship

• Diplomatic protection in situations of risk abroad

A second citizenship is not a tax solution in itself. Its strategic value lies in its appropriate combination with the applicant's tax residency and wealth structure.
