ABSTRACT: From 2026, Italy's annual property tax system for second homes has been restructured, replacing decades of municipal free-form rate-setting with a national framework table — the most significant rationalisation since the tax was unified in 2012. For UK, US and Irish buyers weighing up a holiday home in southern Europe, the reform changes one of the most misunderstood costs in Italian property ownership. This article breaks down what foreign owners actually pay in Italy, how it compares with Spain, Portugal and Greece, and where the real surprises lie.
Imagine you have just signed the notarial deed of sale (
rogito) on a farmhouse in Umbria. The solicitor back home has handled the conveyancing, the Italian notary has registered the transfer, and you are, at last, the owner of a property you will use for six weeks a year. Then, in June and December, two unfamiliar tax notices arrive. Welcome to
IMU.
How much is IMU property tax in Italy for a second home?IMU — the
Imposta Municipale Unica, Italy's unified municipal property tax, introduced by Legislative Decree 504/1992 and later consolidated under Law 160/2019 — applies to virtually every Italian residential property that is not used as the owner's registered primary Italian residence. A holiday home, a rental flat, a pied-à-terre: all are liable.
The calculation has three steps. First, take the property's
rendita catastale — its official cadastral income, a figure set by the land registry (
catasto) that typically dates from the 1980s or 1990s and bears little relation to market value. Multiply that figure by 1.05 to revalue it, then by a coefficient of 160 (the statutory multiplier for residential property). The result is the IMU tax base. Apply the municipal rate — which, for second homes, has historically ranged between 0.86% and 1.06%, with some municipalities pushing as high as 1.14% for vacant properties — and you have your annual liability, payable in two instalments in June and December.
The practical consequence is that IMU liabilities in Italy are often far lower than buyers fear. A two-bedroom apartment near Lake Garda with a market value of €400,000 might carry a
rendita catastale of only €1,200. The tax base works out at approximately €201,600. At a municipal rate of 1.06%, annual IMU is roughly €2,137. For a coastal villa in Puglia worth €600,000 but with an equally antiquated cadastral income of €1,800, the bill rises to about €3,024. These are not alarming numbers, and they are lower than many buyers expect when they hear "property tax."
The 2026 reform matters because it changes how reliably you can plan. Before this year, Italy's approximately 7,900
comuni each published their own rate schedules in formats ranging from detailed PDF tables to hand-typed council resolutions, making any systematic comparison almost impossible. From 2026, the MEF has introduced a structured national rate framework from which municipalities must choose permitted rates, with submissions made through a standardised digital portal and consolidated into a searchable national register published by the Dipartimento delle Finanze. This is the first fundamental rationalisation of the IMU rate-setting architecture since the tax was unified in 2012. It will not cap rates, but it will make them findable — a real improvement for foreign buyers researching from Dublin or Denver.
Do foreign owners pay IMU in Italy?Yes — and this is the most costly misconception in Italian property ownership for international buyers. Many UK, US and Irish purchasers assume that because the property is their only real estate worldwide, or because they do not live in Italy, some exemption must apply. It does not.
The IMU exemption for a primary residence (
abitazione principale) requires that the owner be both registered as a resident in that Italian municipality (
residenza anagrafica) and actually live there habitually. A non-resident foreign owner who spends six or eight weeks a year at their Tuscan farmhouse meets neither condition, regardless of whether that property is their sole dwelling on earth.
There is one narrow exception worth noting. Since 2021, Italian law has extended a partial IMU concession — a 50% reduction — to properties owned by pensioners who are tax-resident in a country covered by a social security reciprocity agreement with Italy, provided the property is not let. This benefits some UK retirees living in Italy under the current bilateral arrangements, though how it applies to post-Brexit situations depends on the relevant treaty and must be assessed individually.
Unlike in most common-law countries, Italy charges annual property tax not on open-market value but on a state-set cadastral figure that in many cases is fixed at a fraction of real market worth. A British buyer accustomed to Council Tax in England and Wales — a flat-rate local charge with no direct link to property value — or an American familiar with ad valorem property taxes assessed at or near market value will find the Italian system initially bewildering but often financially advantageous once understood. The cadastral system functions, in practice, as a structural subsidy to property owners at the expense of fiscal precision, and successive governments have left it largely intact despite periodic reform promises.
Is Italy property tax higher than Spain or Portugal?Comparing annual holding costs across southern European jurisdictions requires separating the headline rate from the effective liability, since each country uses a different base.
In Spain, the main annual property charge is the
Impuesto sobre Bienes Inmuebles (IBI), levied by the municipality on a cadastral value that is periodically revised (more frequently than in Italy) at rates typically ranging from 0.4% to 1.3% of the cadastral value. However, non-resident owners of Spanish property — UK, US and Irish nationals among them — face an additional annual tax:
Impuesto sobre la Renta de No Residentes (IRNR). Even if the property is not rented out, Spain imputes a notional rental income — generally 1.1% or 2% of the cadastral value, depending on when it was last revised — and taxes that imputed income at 19% (EU and EEA residents) or 24% (non-EU residents). For a British owner after Brexit, the 24% rate applies. The combined Spanish annual burden, IBI plus IRNR, regularly exceeds the Italian IMU bill for a comparable property.
In Portugal, the annual property charge is the
Imposto Municipal sobre Imóveis (IMI), levied at rates between 0.3% and 0.45% for urban property, applied to a fiscal value that tends to be closer to market reality than Italy's cadastral values, having been more recently revised. Properties worth over €600,000 attract an additional surcharge, the
Adicional ao IMI (AIMI), charged at 0.7% on the excess above that threshold (rising to 1% above €1 million and 1.5% above €2 million). Portugal's IMI alone is generally lower than Italian IMU in percentage terms, but the AIMI surcharge can make high-value Portuguese property meaningfully more expensive to hold than an Italian equivalent.
In Greece, the annual property charge is the
Ενιαίος Φόρος Ιδιοκτησίας Ακινήτων, universally known as ENFIA, a complex tax recalculated annually based on surface area, floor level, age, location coefficients, and use. The Greek system is notoriously difficult to calculate without professional assistance and was substantially reformed in 2022 to introduce a more market-linked approach. For a typical island or coastal holiday property, ENFIA charges are broadly comparable to Italian IMU, though the volatility of annual recalculation creates planning uncertainty that the 2026 Italian reform is specifically designed to reduce.
Across the four jurisdictions, Italy's IMU sits in the middle range for effective annual liability. Its principal structural advantage for foreign owners is the gap between cadastral value and market value, which in rural areas and smaller cities can be very large. Its principal disadvantage, until now, has been opacity and municipal unpredictability — the problem the 2026 reform addresses directly.
What property taxes do I pay annually on an Italian holiday home?IMU is not the only annual cost. Foreign owners should budget for the following each year.
IMU itself, as described, payable in June (first instalment, calculated on the previous year's rates) and December (final instalment, using current-year rates as determined by the municipality before 31 October).
Rubbish collection tax (
TARI), a separate municipal levy for waste services, calculated on the surface area of the property. For a 100-square-metre apartment, TARI typically runs from €150 to €400 per year depending on the municipality.
Condominium service charges (
spese condominiali), where the property is part of a building with shared areas. These vary enormously and are not a tax, but they are a predictable annual cost between €500 and €3,000 for a typical apartment.
If the property is rented out — even occasionally — the foreign owner may also be liable to Italian income tax on rental income under Italian domestic law, subject to treaty relief under the relevant double taxation agreement. The UK-Italy Double Taxation Convention of 1988 and the US-Italy Tax Treaty of 1999 both allocate primary taxing rights over Italian rental income to Italy, with credit or exemption mechanisms in the country of residence.
The cadastral reform question nobody is askingHere is the risk that most comparisons overlook. Italy's cadastral values have not been systematically revised since 1988–1992. This is legally documented and fiscally consequential. The Italian Constitutional Court (
Corte Costituzionale), in its judgment no. 176 of 18 July 2024 (Corte Cost., sent. 18 luglio 2024 n. 176), addressed the constitutional legitimacy of the cadastral system in the context of property taxation, observing the structural divergence between cadastral and market values without mandating immediate reform — but placing the question squarely in constitutional focus. Separately, the Italian government's enabling law for fiscal delegation — Law 111 of 9 August 2023 (Legge 9 agosto 2023 n. 111) — contains a mandate to revise the cadastral classification criteria, though implementing decrees have proceeded cautiously.
The Italian Court of Cassation, United Sections, judgment no. 12169 of 7 May 2024 (Cass. civ., Sezioni Unite, sent. 7 maggio 2024 n. 12169), confirmed the interpretive hierarchy governing IMU exemptions, reaffirming that the dual requirement of registered residence and habitual habitation is cumulative, not alternative — meaning that a foreign owner who registers formally at an Italian address without genuinely living there cannot claim the primary residence exemption.
The practical implication for foreign buyers is this: Italy's annual IMU bills are low today partly because cadastral values are artificially low. If and when cadastral reform arrives — and Law 111/2023 keeps it firmly on the legislative agenda — annual holding costs for foreign owners could rise significantly without any change in nominal rates. A buyer comparing IMU in 2026 with ENFIA or IBI should factor this latent risk into a long-term cost model.
As the economist John Kenneth Galbraith observed, "the modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness." Cadastral conservatism in Italy has, for decades, served much the same function: an intellectually indefensible system that happens to benefit those who already own property.
Nemo debet bis vexari pro una et eadem causa — no one should be troubled twice for one and the same matter. This maxim from Roman procedure is worth keeping in mind: a property owner already paying IMU in Italy may also face obligations in their country of residence, and the interaction between Italian local taxation and foreign income or wealth taxes requires specific treaty analysis, not general assumptions.
For a foreign owner making a genuine long-term investment in Italian property, the 2026 rate reform improves transparency without resolving the deeper uncertainty around cadastral values. The annual cost of holding an Italian holiday home is, today, often lower than comparable costs in Spain or at the high-value end of Portugal — but that comparison rests on a cadastral fiction that Italian legislators have so far lacked the political will to correct.

LOCAL NOTE:
1. Search intent: informational with transactional edge — reader is in pre-purchase or early ownership phase, comparing jurisdictions, and likely to instruct a lawyer once costs are clarified.
2. Local-market framing: anchored to UK/Irish/US buyer experience — contrasted with Council Tax (England and Wales) and US ad valorem systems to make the Italian cadastral model legible; post-Brexit IRNR rate for UK owners in Spain used as a pointed contrast.
3. Italian terms kept: rendita catastale (no English equivalent captures the administrative-historical specificity of Italy's cadastral income figure; explained on first use and used once thereafter in italics); abitazione principale (used once in italics to flag the Italian legal test, not used as a running term); TARI (acronym in common use even in English-language Italian property contexts; explained on first use).
