TL;DR: Argentina now uses a single tax ID for property, the CUIT (it replaced the old CDI that foreigners once received). You need it to buy. To rent the property out and declare the rental income, you keep that same CUIT but register it for economic activity and file accordingly. In short: one CUIT to own, plus activity registration and filing once you let. An accountant sets this up; it is routine.
Argentina's tax identifiers confuse every foreigner, and the old CDI-versus-CUIT split no longer applies. Here is the clean, current version.
| ID | Who it is for | Used to |
|---|---|---|
| DNI | Residents and citizens | National ID — not needed to buy |
| CUIT | Everyone: locals and foreigners alike (foreigners once got a CDI instead) | Buy and hold property; and, once registered for economic activity, declare income such as rent |
You do not need a DNI to buy property; you need a CUIT. That is covered in our note on getting a CUIT. Registering that CUIT for economic activity is the next step only if you generate income from the property.
Your CUIT lets you own. The moment you rent the property out and earn income, you enter the territory of declaring that income — which means registering your CUIT for economic activity and filing on it. Rental income in Argentina is taxable, and a compliant foreign landlord files on it.
This is not a hurdle so much as a step: an accountant registers the activity and handles the filings. Foreign owners who let their property do this as a matter of course.
Yes. A foreigner buys with a CUIT — the single tax ID Argentina issues to residents and non-residents alike, which replaced the old CDI. Renting the property out later doesn't need a different ID; it adds registering that CUIT for economic activity.
Yes. Foreign buyers used to be issued a CDI (Clave de Identificación). Argentina has unified that into the CUIT (Clave Única de Identificación Tributaria), the same numeric tax ID residents carry. If an older guide mentions a CDI, read it as today's CUIT.
Yes. Rental income earned in Argentina is taxable, and a compliant foreign landlord registers the activity and files on it, with a CUIT and an accountant.
Yes. Registering the CUIT for economic activity and handling rental-income filings is routine work for a local accountant, and foreign owners who let their property normally do exactly this.
Owning and operating are two different tax steps, and getting the second right keeps your rental income clean. To set up the right structure before you let, book a call.
