Getting a CUIT as a UK Buyer: Tax ID for Argentine Property Purchases
How to obtain a CUIT (Argentine tax ID) as a British citizen buying property: the process, documents needed, how long it takes, and what you can do once you have it.
Thomas SinclairWriter and editor · London
Every property purchase in Argentina requires the buyer to have a CUIT (Clave Única de Identificación Tributaria) — the Argentine tax identification number for individuals and businesses. This is different from the CUIL (which is for workers) and the CDI (a basic non-worker tax ID).
For a British citizen buying property without Argentine residency, obtaining a CUIT is straightforward but requires specific steps.

Who needs a CUIT
Any person buying, selling, or holding Argentine property needs a CUIT for:
- The property title registration (Registro de la Propiedad)
- Payment of stamp taxes and transfer taxes at closing
- Ongoing municipal property tax (ABL/ARBA) payments
- Income tax declarations if you rent the property out
- Bienes Personales (wealth tax) if applicable
Without a CUIT, the escribano cannot register the property in your name.
How to get a CUIT as a foreign buyer
Option 1: through an Argentine accountant (most common)
Your accountant (contador) or your escribano's office can handle the entire process:
1. You provide: passport copy, proof of Argentine address (can be the property address you are buying, or a hotel/Airbnb), and a notarised power of attorney (poder especial) if you are not in Argentina
2. The accountant submits the application to AFIP (Administración Federal de Ingresos Públicos) online
3. AFIP processes and assigns the CUIT number
4. You receive the CUIT within 3-7 working days
Cost: the CUIT itself is free from AFIP. The accountant's fee for handling the application is typically USD 100-300.
Option 2: in person at AFIP
If you are in Argentina, you can visit an AFIP office directly:
- Bring your passport, proof of address, and a completed formulario 460/F
- Queue at the AFIP office (bring patience and a book)
- The CUIT is usually issued the same day
This is cheaper (no accountant fee) but more time-consuming and language-dependent.
Once you have the CUIT
Your CUIT is a permanent number. it does not expire. Once issued, you use it for:
- Property purchase — the escribano registers the property under your CUIT
- Tax obligations — you file Argentine tax returns (if required) using the CUIT
- Monotributo — if you later become self-employed, the CUIT is your tax registration
- Business activities — if you set up a company, the CUIT connects to your entity
If you later obtain a DNI and Argentine residency, your CUIT links automatically to your new status.
Common questions
"Do I need to be in Argentina to get a CUIT?"
No. Your accountant can apply with a notarised power of attorney (poder especial) granted at the Argentine consulate in London or another city. This is common for UK buyers purchasing remotely.
"Is CUIT the same as CUIL?"
Different but related. CUIL is for workers (issued by ANSES). CUIT is for tax purposes (issued by AFIP). Some people have both with the same number in different formats. For property, you need the CUIT.
"Can I get the CUIT before I arrive in Argentina?"
Yes, through your accountant or escribano using power of attorney.
"Does the CUIT create tax obligations?"
Having a CUIT does not automatically create tax obligations. Only specific activities (earning income, owning property above thresholds, conducting business) trigger filing requirements.
Not tax advice. A CUIT is a tool; your actual tax position depends on residency, income sources, and property values. Consult an Argentine accountant before and after purchasing.

Frequently Asked Questions
How long does it take to get a CUIT?
3-7 working days through an accountant. Same-day if you visit an AFIP office in person. The application itself is simple — the wait is mostly processing time.
Does having a CUIT mean I pay Argentine taxes?
Not automatically. The CUIT is a registration number. Tax obligations arise from specific activities: earning income, owning property above thresholds, or conducting business. Property ownership may trigger property tax and wealth tax.
Can I buy Argentine property without being a resident?
Yes. Foreign non-residents can buy most urban property. You need a CUIT (tax ID) and typically an Argentine bank account for the transaction, but residency is not required.
How much does it cost to get a CUIT?
The CUIT itself is free from AFIP. An Argentine accountant handling the application charges USD 100-300. In person at AFIP is free but requires more time.
