What Tax Numbers Do I Need to Buy Property Abroad?

Every European country has its own tax identification system, and you cannot buy property - or even open a bank account - without one. Get yours before you start seriously looking at properties.

Portugal uses the NIF (Número de Identificação Fiscal). It's free. Visit any Finanças (tax office) with your passport and you'll have one in 15 minutes. If you're not in Portugal, hire a fiscal representative (€100-200) who can obtain it remotely. Required for property purchases, bank accounts, utility contracts, basically everything financial.

Spain uses the NIE (Número de Identificación de Extranjero). Cost is minimal (around €10). Get it at a Spanish consulate before traveling, or at a police station (Comisaría) once in Spain. Here's the frustrating part: processing times vary wildly. Some consulates handle it in a week. Some Spanish cities have 6-week backlogs. Apply early. Required for literally every legal and financial transaction.

Italy uses the Codice Fiscale. Free. Walk into any Italian consulate or Agenzia delle Entrate office with your passport. Same-day issuance is normal. It's essentially a tax identification number that also functions as your ID for contracts. Required for property purchase, phone contracts, utilities, banking.

Greece uses the AFM (Arithmos Forologikou Mitroou). Free. Obtain it at any DOY (tax office) in Greece. Same-day processing. You'll need your passport and potentially proof of address. Required for property purchase, banking, utilities.

What you'll need to apply: passport (always), proof of address from your home country (usually), passport photos (sometimes). Some countries accept apostilled documents, others want originals. Check specific requirements before you go.

Pro tip: get your tax number on your first visit to a country, even if you're just exploring. Having it ready speeds everything up when you find the property you want.
