Everything you need to know before buying real estate is included in our Argentina Property Pack
The CDI tax ID is an essential requirement for all foreigners purchasing property in Argentina.
Without this identification number, foreign buyers cannot legally register property ownership or complete the transaction process. The CDI system ensures tax compliance and provides legal identification for non-residents engaging in Argentine real estate transactions.

The CDI (Clave de Identificación) is a tax identification number specifically issued to foreigners who need to buy property in Argentina but don't qualify for local CUIT or CUIL numbers.
The process requires physical presence in Argentina, takes 1-2 weeks, and involves minimal fees while requiring a local address certificate.

What exactly is a CDI tax ID in Argentina and how does it differ from the CUIT or CUIL numbers locals use?
The CDI (Clave de Identificación) is a numeric tax identification code issued specifically to foreigners who need formal identification for property transactions in Argentina.
Unlike local identification systems, the CDI is designed for non-residents who don't qualify for standard Argentine tax numbers. The CUIT (Código Único de Identificación Tributaria) is assigned to individuals or entities engaged in regular business activities and tax obligations, while the CUIL (Código Único de Identificación Laboral) is for people working in Argentina or participating in the social security system.
The key distinction is that CDI holders are typically foreigners with no long-term plans to reside, work, or operate businesses in Argentina. They simply need official identification for specific transactions like real estate purchases. As of September 2025, the CDI system remains the primary pathway for foreign property buyers to establish legal identification with Argentine tax authorities.
The CDI enables property registration with Argentina's public registry system and ensures compliance with tax obligations related to property ownership, including annual property taxes and potential income tax on rental earnings.
Why is the CDI specifically required for foreigners who want to buy property?
The CDI requirement exists because Argentina's property registration system requires all owners to have official tax identification for legal and regulatory compliance.
Foreign property buyers must demonstrate their tax identity to complete property transfers and register ownership with Argentina's public property registry. Without a CDI, foreigners cannot legally complete property transactions or hold registered title to real estate. The system ensures that all property owners, regardless of nationality, are properly identified within Argentina's tax framework.
This requirement also facilitates future tax obligations related to property ownership, such as annual property taxes, potential rental income reporting, and capital gains tax when selling. The CDI creates a direct link between the foreign owner and Argentina's tax administration system.
It's something we develop in our Argentina property pack.
At what stage in the property purchase process do foreigners need to present the CDI?
Foreigners must obtain and present their CDI before completing the property purchase and registering the title with Argentina's public registry.
The CDI is typically required early in the transaction process, ideally before signing the final purchase contract. Most notaries and real estate professionals recommend obtaining the CDI during the due diligence phase, after identifying a property but before committing to purchase.
At the latest, the CDI must be available during the escritura (deed signing) process, which is when ownership officially transfers. The notary requires the CDI to complete property registration with the public registry and ensure legal compliance with Argentine property law.
Smart buyers obtain their CDI immediately upon deciding to purchase property in Argentina, as the 1-2 week processing time can potentially delay transactions if left until the last minute.
Which government office or authority issues the CDI to foreigners?
AFIP (Administración Federal de Ingresos Públicos), Argentina's federal tax authority, is the sole issuing body for CDI numbers.
AFIP operates offices throughout Argentina where foreigners can apply for their CDI in person. Major cities like Buenos Aires, Córdoba, Rosario, and Mendoza have multiple AFIP locations that handle CDI applications. The process must be completed at an official AFIP office, as no other government agency or private entity has authority to issue CDI numbers.
Applicants should locate their nearest AFIP office and confirm operating hours before visiting, as appointment systems may be required in some locations. The AFIP website provides office locations and current operational information for CDI applications.

What documents does a foreigner need to bring to apply for a CDI?
Foreign CDI applicants must bring their original passport, photocopies of passport pages, proof of Argentine address, and completed application forms.
The most critical requirement is the "certificado de domicilio" (domicile certificate), which proves the applicant has a verifiable address in Argentina. This certificate must be obtained from a local police station by showing documentation of where the applicant is staying, such as a hotel reservation, rental agreement, or letter from a host.
Additional required documents typically include completed AFIP application forms (often available at the office or online), and sometimes a power of attorney if the application is being handled through a legal representative or notary. Some AFIP offices may request additional identification verification depending on the applicant's country of origin.
All documents should be current and some offices may require certified translations for certain foreign documents, though this varies by location and officer discretion.
How long does it usually take to obtain a CDI once the application is submitted?
CDI processing typically takes 1-2 weeks after application submission, depending on AFIP's current workload and document verification requirements.
Processing times can vary slightly based on the specific AFIP office location and the time of year, with some locations potentially taking up to 3 weeks during busy periods. The verification process includes confirming the applicant's address certificate and cross-checking passport information with immigration records.
Applicants receive their CDI number electronically or can collect it in person at the issuing AFIP office once processing is complete. Some offices provide tracking systems that allow applicants to monitor their application status online.
Foreign buyers should plan for potential delays and apply for their CDI well in advance of any planned property purchase timeline to avoid transaction complications.
Is there a cost or fee involved in applying for a CDI, and if so, how much?
CDI applications involve minimal costs, with the primary expense being the domicile certificate fee of approximately 15 Argentine pesos (about USD $3.50 as of September 2025).
The actual CDI registration at AFIP is typically free or carries only negligible administrative processing fees. However, applicants should budget for potential additional costs such as photocopying documents, transportation to AFIP offices, and possible notary fees if using legal representation.
Some applicants choose to hire local attorneys or notaries to assist with the CDI application process, which can cost between $50-200 USD depending on the service provider and location. This additional cost is optional but can be valuable for foreigners unfamiliar with Argentine bureaucratic processes.
Overall, the direct government fees for obtaining a CDI remain very affordable compared to property transaction values, making cost a minimal barrier for foreign property buyers.
Does a foreigner need to have a local address or sponsor in Argentina to get a CDI?
Yes, foreigners must provide a verifiable local Argentine address to obtain a CDI, but no sponsor is required for the application process.
The local address requirement is fulfilled through the certificado de domicilio (domicile certificate) obtained from a local police station. This address can be temporary, such as a hotel, short-term rental, or accommodation with friends or family. The police station verifies the address exists and the applicant can demonstrate they are staying there.
No sponsor, guarantor, or local reference person is needed for CDI applications. However, many foreigners choose to work with local real estate attorneys or notaries who can provide guidance through the process and assist with address documentation if needed.
It's something we develop in our Argentina property pack.
The address used for CDI application doesn't need to be permanent or long-term, making it accessible for foreign buyers who are visiting Argentina specifically for property transactions.
Can the CDI be obtained outside Argentina, or does it require being physically present in the country?
Physical presence in Argentina is absolutely required for CDI applications - the process cannot be completed from abroad or through consulates.
AFIP requires in-person verification of identity and address documentation, which necessitates being physically present in Argentina. The domicile certificate requirement alone requires applicants to visit a local police station within Argentina, making remote application impossible.
This requirement means foreign property buyers must plan to travel to Argentina before or during their property search process. Many buyers combine their CDI application with property viewing trips to maximize efficiency.
Some legal representatives or notaries can assist with CDI applications, but the applicant must still be physically present in Argentina to provide documentation and complete the identification verification process at AFIP offices.

Is the CDI linked to taxes beyond property ownership, such as rental income or capital gains when selling?
Yes, the CDI serves as the primary tax identification for all tax obligations related to the foreign owner's Argentine activities, including rental income and capital gains.
When foreign property owners earn rental income from their Argentine properties, they must report this income using their CDI number. Argentina's tax system requires rental income declaration and payment of appropriate income taxes, with the CDI serving as the identification link for these obligations.
Capital gains taxes from property sales are also reported under the CDI number when foreigners sell their Argentine real estate. The CDI essentially becomes the foreign owner's tax identity for all property-related financial activities in Argentina.
Foreign owners should maintain records of all property-related income and expenses under their CDI number and may need to file annual tax returns depending on their total Argentine income levels. Consulting with Argentine tax professionals is recommended for understanding ongoing tax obligations.
What risks or complications can occur if a foreigner tries to buy property without a CDI?
Attempting to purchase property without a CDI makes it impossible to legally register ownership and complete the transaction, creating significant legal and financial risks.
Without a CDI, the property registration process cannot be completed with Argentina's public registry, meaning the buyer cannot obtain legal title to the property. This leaves the buyer without legal ownership rights and potential legal complications if disputes arise.
Additionally, transactions attempted without proper CDI identification may violate Argentine tax regulations and property laws, potentially resulting in penalties, blocked transactions, or legal proceedings. Banks and notaries will refuse to process property transfers without valid CDI documentation.
The financial risks include losing deposit money, facing legal costs to resolve documentation issues, and potential delays that could result in losing the desired property to other buyers who have proper documentation.
It's something we develop in our Argentina property pack.
Once a foreigner has a CDI, is it valid indefinitely, or does it need renewal or updates over time?
CDI numbers are valid indefinitely and do not require renewal or regular updates under normal circumstances.
However, if key information associated with the CDI changes - particularly the registered address in Argentina - the CDI holder may need to update their information with AFIP. This is especially relevant for foreign owners who change their Argentine address or contact information.
The CDI remains active and usable for all future property-related transactions, tax filings, and legal requirements without expiration dates. This makes it a one-time investment in establishing Argentine tax identification for foreign property owners.
Foreign owners should keep their CDI documentation safe and accessible, as they will need to reference this number for all future property-related activities, tax filings, and potential property sales in Argentina.
