Self-assessed tax. Overseas owners generally do not receive an IMU invoice. Missing typical 16 June / 16 December deadlines can trigger penalties. Confirm each Comune’s rate every year — this page does not invent municipal rates.
Readers searching for property tax in Italy for foreigners, Italian property tax for non-residents, or IMU Italy AIRE usually need the same answers: Who pays? Is AIRE exempt? How do I pay from abroad? How does IMU relate to rent or a sale? This page stays focused on IMU while linking related filing and property steps.
What IMU is — and who usually pays
IMU (Imposta Municipale Propria) is Italy’s main municipal tax on buildings and land. Primary-residence exemptions are tied to living in the property as your Italian residence (with cadastral-category limits). Non-resident and AIRE owners almost always treat Italian homes as second homes for IMU purposes — AIRE registration confirms you are not resident in that Comune; it does not create a general exemption.
- Owners and holders of real rights (including many co-ownership / inheritance quote)
- Holiday homes, investment properties, vacant dwellings held from abroad
- Luxury cadastral categories that remain taxable even when used as a main home
Foreign and non-resident owner patterns
International owners typically face IMU because the property is in Italy, not because they live in Italy. Common patterns:
- U.S. or Canadian residents holding a second home or inherited share
- AIRE-registered Italian citizens living abroad
- Co-owners who must pay IMU in proportion to their ownership share
- Heirs who may face IMU timing questions from the date of death — confirm with the Comune and succession timeline

How it is generally calculated
IMU is typically based on cadastral income (rendita) revalued and multiplied by statutory coefficients, then by the municipal rate within legal bands. Each Comune publishes annual rates. Your Comune’s deliberation is the source of truth — not a generic English blog rate.
Deadlines and F24 — practical pain points
- 16 June — first instalment (acconto), often based on prior-year rates; full annual payment may be allowed
- 16 December — balance (saldo), adjusted to the current year’s approved rates
- Payment via Modello F24 (or authorised digital channels). Casual foreign-bank wires without a proper F24 path are a frequent failure mode
TARI, rentals, filing, and sales
TARI (waste tax) follows municipal billing and is separate from IMU. If the property is rented, income-tax filing usually sits beside IMU — see Italian income tax filing obligation and rental income for non-residents. A sale or capital-gains question is not solved by IMU alone — review selling property in Italy from abroad before accepting offers. Purchase-stage taxes are covered in the buying property guide.
A narrow 50% IMU reduction for certain AIRE pensioners under international totalisation conventions exists in statute, with strict conditions (typically one Italian residential property, not rented/loaned). Do not assume entitlement.
