If you're weighing up a property purchase in southern Europe, understanding the Portugal vs Italy property tax landscape is essential before signing any contract. Both countries attract a steady stream of foreign buyers—retirees chasing sunshine, digital nomads seeking lifestyle upgrades, and investors hunting for rental yields—but their property tax systems differ in important ways that can add up to thousands of euros every year.
In this comprehensive property tax comparison for the 2025/2026 tax year, we break down every levy you'll encounter when buying, owning, and selling real estate in Portugal and Italy. By the end, you'll know exactly which costs to expect, which exemptions you might qualify for, and how to model your own numbers using our free calculators.
Overview: How Property Tax Works in Portugal and Italy
Before diving into rates and thresholds, it helps to understand the structural differences between the two systems.
Portugal levies property tax primarily through:
- IMI (Imposto Municipal sobre Imóveis) — the annual municipal property tax
- IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) — the transfer tax paid on purchase
- AIMI (Adicional ao IMI) — a wealth-style surcharge on higher-value portfolios
- Stamp Duty (Imposto do Selo) — applied at purchase
Italy levies property tax mainly through:
- IMU (Imposta Municipale Unica) — the annual municipal property tax
- Imposta di Registro / IVA — the transfer tax or VAT paid at purchase
- Imposta Ipotecaria e Catastale — mortgage and cadastral taxes at purchase
- TARI — waste collection tax (separate but mandatory)
Both countries give municipalities considerable discretion over rates, so the exact bill depends on where the property is located. Let's explore each layer in detail.
Annual Property Tax: Portugal's IMI vs Italy's IMU
The annual property tax is the cost you'll pay every year for as long as you own the property, making it the single most important factor in a long-term tax comparison Portugal Italy.
Portugal — IMI (Imposto Municipal sobre Imóveis)
| Feature | Detail |
|---|---|
| Tax base | VPT (Valor Patrimonial Tributário) — the tax-assessed value, often below market value |
| Urban property rates | 0.3 %–0.45 %, set by each municipality |
| Rural property rates | 0.8 % flat |
| Reassessed properties | Some municipalities offer a reduced rate of 0.3 % for recently reassessed buildings |
| Payment schedule | April (single instalment if ≤ €100), April & November (if €100–€500), April, July & November (if > €500) |
Key point: The VPT is calculated using a formula that factors in location, age, construction quality, and size. It frequently sits 20–50 % below true market value, which keeps the effective tax rate quite low.
Practical Example — Lisbon Apartment
Suppose you buy an apartment in Lisbon with a market value of €350,000 and a VPT of €220,000. Lisbon's IMI rate for 2025 is 0.3 %.
- Annual IMI = €220,000 × 0.3 % = €660
Italy — IMU (Imposta Municipale Unica)
| Feature | Detail |
|---|---|
| Tax base | Rendita catastale (cadastral income) × revaluation coefficient × property-type multiplier |
| Standard national rate | 0.76 % (7.6 ‰), but municipalities can adjust between roughly 0.46 % and 1.06 % |
| Primary residence | Exempt from IMU (except luxury categories A/1, A/8, A/9) |
| Payment schedule | Two instalments — 16 June (advance) and 16 December (balance) |
Key point: Italy's cadastral values are notoriously outdated and typically represent only a fraction (sometimes 30–60 %) of market value. However, the multipliers (160 for most residential property) push the taxable base back up, and municipal rates can be steep.
Practical Example — Rome Apartment (Second Home)
You purchase an apartment in Rome with a market value of €350,000. The rendita catastale is €1,200.
- Revalued rendita = €1,200 × 1.05 = €1,260
- Taxable base = €1,260 × 160 = €201,600
- Rome's IMU rate for second homes in 2025 is 1.06 %
- Annual IMU = €201,600 × 1.06 % = €2,137
Head-to-Head: Annual Tax
For a comparable €350,000 property, a Portugal owner might pay around €660/year while an Italy second-home owner could face roughly €2,137/year — more than three times as much. This gap is one of the most significant findings in any Portugal vs Italy property tax analysis.
However, if the Italian property is your primary residence, IMU drops to €0 for most property categories, giving Italy a major advantage for people who actually live there.

Property Transfer Taxes: Buying Costs Compared
The upfront taxes paid when you acquire a property can significantly affect your total investment. Here's how Portugal and Italy stack up.
Portugal — IMT and Stamp Duty
IMT is a progressive transfer tax with rates that depend on the property value, type, and whether it will be your primary residence:
| Property Value (Urban, Primary Residence) | IMT Rate |
|---|---|
| Up to €101,917 | 0 % |
| €101,917–€139,412 | 2 % |
| €139,412–€190,086 | 5 % |
| €190,086–€316,772 | 7 % |
| €316,772–€633,453 | 8 % |
| Over €633,453 (or bought by non-habitual use) | 6 % flat (secondary) / 7.5 % (luxury) |
Note: For secondary or investment properties, a flat 6.5 % rate applies for most values, with a 7.5 % rate above €1,102,920 (2025 brackets — always verify current thresholds).
Stamp Duty (Imposto do Selo) is an additional 0.8 % of the declared purchase price or VPT (whichever is higher).
Example — Buying a €350,000 Primary Residence in Lisbon
- IMT ≈ €18,207 (after applying the progressive marginal formula)
- Stamp Duty = €350,000 × 0.8 % = €2,800
- Total transfer taxes ≈ €21,007
Italy — Registration Tax, Mortgage Tax, and Cadastral Tax
Italy's purchase taxes depend on whether you're buying from a private seller or a developer (VAT regime).
Buying from a private seller (most resale properties):
| Tax | Primary Residence | Second Home |
|---|---|---|
| Imposta di Registro | 2 % of cadastral value (min. €1,000) | 9 % of cadastral value |
| Imposta Ipotecaria | €50 fixed | €50 fixed |
| Imposta Catastale | €50 fixed | €50 fixed |
Buying from a developer (new build, subject to VAT):
| Tax | Primary Residence | Second Home |
|---|---|---|
| VAT (IVA) | 4 % of sale price | 10 % of sale price (22 % for luxury) |
| Imposta di Registro | €200 fixed | €200 fixed |
| Imposta Ipotecaria | €200 fixed | €200 fixed |
| Imposta Catastale | €200 fixed | €200 fixed |
Example — Buying a €350,000 Resale Property as a Second Home in Rome
Using the same cadastral base of €201,600:
- Registration Tax = €201,600 × 9 % = €18,144
- Mortgage + Cadastral = €100
- Total transfer taxes ≈ €18,244
Example — Buying the Same Property as a Primary Residence
- Registration Tax = €201,600 × 2 % = €4,032
- Mortgage + Cadastral = €100
- Total transfer taxes ≈ €4,132
Transfer Tax Comparison at a Glance
| Scenario (€350k property) | Portugal | Italy |
|---|---|---|
| Primary residence purchase | ~€21,000 | ~€4,100 (resale) |
| Second / investment home purchase | ~€25,500 | ~€18,200 (resale) |
Takeaway: Italy's primera casa (first/primary home) incentives are dramatically more generous than Portugal's progressive IMT scale. For primary-residence buyers, Italy offers a clear advantage on transfer taxes. For second-home or investment buyers, the difference narrows but Italy still edges ahead in most scenarios.
Wealth Surcharges and Additional Levies
Portugal — AIMI (Adicional ao IMI)
Portugal introduced AIMI as a supplementary tax on the aggregate VPT of all urban residential properties owned by a single taxpayer:
- VPT up to €600,000: exempt
- €600,000–€1,000,000: 0.7 %
- Above €1,000,000: 1.0 %
- Corporate-owned residential property: 0.4 % (general) or 7.5 % (if the owner is based in a blacklisted jurisdiction)
Married couples filing jointly effectively double the exemption threshold to €1,200,000.
Italy — No Direct Equivalent
Italy does not impose a comparable nationwide wealth surcharge specifically on property. However, Italian residents who own property abroad must pay IVIE (Imposta sul Valore degli Immobili all'Estero) at 1.06 % of the property's value — worth noting for Italian tax residents who also own Portuguese real estate.
Additionally, Italy's TARI (waste tax) is not trivial. Depending on the municipality and property size, TARI can range from €150 to €500+ per year, adding to the effective ownership cost.
Non-Resident Property Owners: Special Considerations
Many buyers of Portuguese and Italian property are non-residents — and both countries impose specific rules on them.
Portugal Non-Resident Rules
- Non-residents pay IMI at the same rates as residents.
- Rental income is taxed at a flat 25 % rate (or progressive rates if the taxpayer opts to be treated as a resident for tax purposes).
- Capital gains on property sales are taxed at 28 % on the full gain for non-residents (residents are taxed on only 50 % of the gain at progressive rates, making the effective rate lower).
- A tax representative in Portugal was historically required for non-EU/EEA residents, though rules have been relaxed for EU/EEA citizens.
Italy Non-Resident Rules
- Non-residents pay IMU at standard rates (no primary-residence exemption, since they don't reside there).
- Rental income can be taxed under the cedolare secca flat-rate regime at 21 % (long-term) or 26 % (short-term, applicable from the second short-let property onward, per 2024/2025 changes). Otherwise, standard progressive IRPEF rates apply.
- Capital gains on property held less than 5 years are taxable (26 % substitute tax or progressive IRPEF). Property held more than 5 years is generally exempt from capital gains tax — a notable advantage.
- Non-EU buyers face no additional restrictions but should verify municipal-level surcharges.

Double Taxation Treaties and Cross-Border Issues
Portugal and Italy have an extensive network of double taxation agreements (DTAs) with other countries. Under most treaties following the OECD model, property income and gains are taxable in the country where the property is situated, with the taxpayer's country of residence providing a credit or exemption to avoid double taxation.
Key Points to Remember
- Portugal–Italy DTA: If you are an Italian resident owning Portuguese property (or vice versa), the DTA between the two countries (signed in 1980) assigns primary taxing rights on real-estate income to the country where the property is located.
- EU residents generally find it easier to navigate compliance thanks to mutual information-exchange agreements.
- Non-EU investors (e.g., from the US, UK, Brazil) should verify treaty relief availability. Both Portugal and Italy have treaties with most major economies.
Common Mistakes
- Assuming primary-residence exemptions apply to non-residents. Italy's IMU exemption and reduced registration tax only apply if you genuinely reside there.
- Forgetting AIMI in Portugal. Buyers accumulating a portfolio often overlook the surcharge that kicks in above €600,000 in aggregate VPT.
- Ignoring municipal rate variation. A property in a low-rate Portuguese municipality (0.3 % IMI) vs. a high-rate Italian municipality (1.06 % IMU) produces vastly different annual bills.
- Overlooking Italy's 5-year capital gains rule. Selling after five years in Italy can mean zero capital gains tax, while Portugal always taxes non-resident gains at 28 %.
Frequently Asked Questions (FAQ)
Which country has lower annual property tax — Portugal or Italy?
For second homes and investment properties, Portugal's IMI is generally much lower than Italy's IMU. For primary residences, Italy wins because most homes are fully exempt from IMU, whereas Portugal still charges IMI regardless of residency status.
Do I pay property tax in Portugal if I live there full-time?
Yes. Unlike Italy, Portugal does not exempt primary residences from IMI. However, some municipalities offer temporary IMI exemptions for newly built or newly purchased properties (typically 3 years) and for lower-income families.
Is it cheaper to buy property in Portugal or Italy?
Upfront transfer taxes are usually lower in Italy for primary-residence buyers, thanks to the prima casa reduced rate of 2 % on cadastral value. Portugal's progressive IMT can be significant on properties above €200,000. However, ongoing annual costs tend to be lower in Portugal, making the long-term total cost comparison more nuanced.

Are there any property tax incentives for retirees?
Portugal's Non-Habitual Resident (NHR) regime—now replaced by the IFICI (Incentivo Fiscal à Investigação Científica e Inovação) regime for new applicants from 2024—offered income tax benefits but did not reduce property taxes. Italy's flat-tax regime for new residents (€100,000/year on foreign income) similarly does not affect property-level taxes. Both regimes focus on income tax, not IMI or IMU.
Conclusion: Portugal vs Italy Property Tax — Which Is Better?
The answer depends on your situation:
If you're buying a primary residence and plan to live there: Italy's IMU exemption and low 2 % registration tax make it the more tax-efficient choice at purchase and during ownership. Portugal will charge you IMI every year plus a higher transfer tax.
If you're buying a second home or investment property: Portugal typically offers significantly lower annual taxes (IMI of 0.3–0.45 % on a conservative VPT vs. IMU up to 1.06 % on a multiplied cadastral base). Italy's transfer taxes for second homes (9 % of cadastral value) are also substantial.
If you're building a portfolio above €600,000 in assessed value: Watch out for Portugal's AIMI surcharge, which can add 0.7–1.0 % on top of IMI.
If you plan to sell within five years: Italy's capital gains tax exemption after five years of ownership is a major planning tool that Portugal doesn't offer to non-residents.
