AIRE registration and fiscal residency in Spain for Italians: complete guide 2026

AIRE registration is the first administrative act an Italian must perform after moving to Spain. Yet many neglect it, do it too late, or confuse it with other formalities. This guide clarifies precisely what AIRE is, what it is not, and how it interacts with fiscal residence in both countries.

What is AIRE and why is it mandatory?

The AIRE — Anagrafe Italiani Residenti all’Estero is the registry of Italian citizens residing abroad, established by Legge 470/1988 of 27 October 1988 and regulated by DPR 323/1989.

Registration is a legal obligation, not a choice. Any Italian citizen who establishes primary residence abroad for more than 12 months must register with AIRE:

• Within 90 days of establishing residence abroad
• With the competent consulate for their area of residence

What AIRE does

• Removes you from the Italian resident municipal register (anagrafe della residenza) of your former Italian municipality
• Registers you in the consular AIRE register for your Spanish district
• Gives you access to Italian consular services in Spain (document renewal, civil registration, emergency assistance)
• Allows you to vote in Italian elections from abroad (Estero constituency)
• Automatically notifies Italian civil and tax authorities of your change of residence status

What AIRE does not do

• It does not automatically make you an Italian fiscal non-resident
• It does not release you from filing a final Italian income tax return (Redditi PF) for the year of departure
• It does not close your partita IVA (separate process)
• It does not eliminate obligations under any ongoing Italian tax audits

The accertamento risk: understanding your exposure

The accertamento (tax audit) from the Agenzia delle Entrate is the main fiscal threat for Italians who do not properly manage their departure.

When can Agenzia delle Entrate challenge your non-residence?

The Agenzia can open an accertamento if it has evidence that you maintained effective residence in Italy despite AIRE registration:

• Primary home in Italy: furnished apartment you return to regularly, children in Italian schools, ongoing service contracts (gas, electricity, phone)
• Business activity in Italy: managing an Italian SRL from Italy, Italian clients met in Italy, prolonged Italian presence
• Significant assets in Italy: movements on Italian bank accounts can reveal undeclared presence
• CRS data: Italian banks automatically share account data with foreign tax authorities under the OECD Common Reporting Standard — and vice versa

Statute of limitations

Documents that prove Spanish residence in an accertamento

• Annual certificados de empadronamiento
• Rental contracts or property deeds
• Spanish IRPF filings
• Spanish bank statements showing regular transactions
• Spanish employment or activity records
• Spanish utility bills (electricity, phone, internet)
• Travel records (flight tickets, transport cards, card transactions in Spain)

Establishing Spanish fiscal residence: required steps

Step 1: Empadronamiento

Register at your Spanish municipality (ayuntamiento). Documents:

• Italian passport or identity card + NIE
• Rental contract or property deed
• Completed solicitud de empadronamiento form

The certificado de empadronamiento is the foundation document for all Spanish administrative procedures.

Step 2: NIE and EU citizen registration

At the Oficina de Extranjería or Comisaría de Policía (appointment required via cita previa):

• Form EX-18 (NIE only) or EX-16 (NIE + EU residency registration for stays > 3 months)
• Valid Italian passport + copy, 2 photos
• Administrative fee: €10.60 (Modelo 790, code 012)

Step 3: Modelo 030 with AEAT

File Modelo 030 with the Agencia Tributaria to officially declare your Spanish fiscal domicile. Available online at sede.agenciatributaria.gob.es (with Cl@ve or electronic certificate) or in person at your AEAT office.

Step 4: Spanish bank account

Open an account with a Spanish bank (BBVA, CaixaBank, Santander, Bankinter, etc.) using your NIE. Regular transactions on this account constitute evidence of active life in Spain.

Step 5: AEAT fiscal residence certificate

Request the Certificado de residencia fiscal from AEAT (procedure G305); the AEAT must issue it within 20 days (Art. 73 RD 1065/2007). This is your official proof of Spanish fiscal residence to present to:

• The Agenzia delle Entrate if audited
• Italian banks and dividend-distributing companies
• Italian withholding agents, to reclaim Italian tax withheld on a private pension (Art. 27)
• Any Italian entity applying withholding tax at source

Convention 1977: claiming reduced Italian withholding

Once you have the AEAT fiscal residence certificate, send it to Italian entities to apply Convention 1977 reduced withholding:

The transition year: coordinating Italy and Spain

Two returns for the year of departure

In the year you move to Spain, you will likely need to file returns in both countries:

Italian Redditi PF (year of departure):

• Income from 1 January to departure date: file as Italian resident (worldwide income)
• Income from departure date to 31 December: file as non-resident (Italian-source income only)
• Indicate departure date and new Spanish address on the return

Spanish IRPF (year of departure):

• Income from date of Spanish fiscal residence to 31 December
• Only if you spend more than 183 days in Spain in the year, or if your centre of economic interests moved to Spain mid-year

No automatic “split year” in Spain

Unlike the UK, Spain does not have a formal split-year treatment. Convention 1977 Art. 4 tie-breakers determine your residence for the full year. The timing of your move (before or after 2 July for the 183-day test) can have significant fiscal consequences.

Italian real estate and the Modelo 720

Owning property in Italy after moving to Spain creates obligations in both countries:

In Italy (as non-resident):

• IRPEF on rental income: 21% cedolare secca or standard IRPEF rate via Redditi PF Non-Residenti
• IMU (Imposta Municipale Unica): due on non-primary Italian properties

In Spain:

• Modelo 720: declare the Italian property if value > €50,000 (purchase price or cadastral value)
• IRPF: declare rental income from Italy in Spanish IRPF; Italian tax paid is credited via Convention 1977 Art. 22(3)
