Owning property in Italy comes with a unique set of tax obligations — but also a generous array of deductions and allowances that many owners overlook. Understanding Italy tax deductions 2025/2026 for property can save you hundreds or even thousands of euros each year. Whether you're a resident homeowner, an expat with a holiday villa, or a non-resident investor, this guide walks you through every major property tax allowance in Italy available for the 2025/2026 tax year.
Italy's property tax framework is complex, spanning municipal taxes (IMU), service levies (TARI), and income-related property charges. But within that complexity lie significant opportunities for Italy tax relief — from principal-residence exemptions and renovation bonuses to energy-efficiency superbonus credits and mortgage interest deductions.
Let's break it all down so you can claim every euro you're entitled to.
Understanding Italy's Property Tax System in 2025/2026
Before diving into deductions and allowances, it's essential to understand the main property taxes you'll encounter in Italy.
IMU (Imposta Municipale Unica)
IMU is the primary municipal property tax levied on real estate ownership. For 2025/2026, the standard base rate remains at 0.76% of the property's cadastral value (rendita catastale), although municipalities can adjust this rate between 0.46% and 1.06%. The cadastral value is calculated by multiplying the registered cadastral income by a category-specific multiplier (e.g., 160 for residential properties in category A, excluding A/10).
Key point: IMU is not levied on the owner's principal residence (abitazione principale), provided it falls into cadastral categories A/2 through A/7. This is the single most valuable property tax allowance in Italy.
TARI (Tassa sui Rifiuti)
TARI is the municipal waste collection tax. It is calculated based on the property's floor area and the number of occupants. While deductions are limited, certain municipalities offer reductions for composting, single-occupant households, or properties located far from waste collection routes.
Income Tax on Property (IRPEF / Cedolare Secca)
Rental income from Italian property is subject to either progressive IRPEF rates (up to 43%) or the flat-rate cedolare secca regime. For 2025, the cedolare secca rate is 21% for standard long-term rentals and 26% for short-term rentals (contracts under 30 days) on second and subsequent properties. Short-term rental income from a taxpayer's first short-let property remains at 21%.

Principal Residence Exemption: Italy's Biggest Property Tax Allowance
The most significant property tax allowance in Italy is the full IMU exemption for your abitazione principale (principal residence). If you live in the property as your habitual and registered residence, and it falls into non-luxury cadastral categories (A/2 to A/7), you pay zero IMU.
What Qualifies as a Principal Residence?
To claim this exemption, two conditions must be met simultaneously:
- Habitual residence (dimora abituale): You must actually live in the property on a day-to-day basis.
- Registered residence (residenza anagrafica): Your official civil registry address must match the property.
Following the landmark Constitutional Court ruling (Sentenza 209/2022), married couples or civil partners who live in different municipalities can each claim the principal residence exemption on their respective homes — a reversal of a previously restrictive interpretation.
Luxury Properties
Properties classified in cadastral categories A/1 (stately homes), A/8 (villas), and A/9 (historic castles and palaces) are still subject to IMU even if used as a principal residence, but they benefit from a reduced rate of 0.4% (adjustable by municipalities between 0.2% and 0.6%) and a EUR 200 deduction applied directly to the tax owed.
Pertinenze (Appurtenant Structures)
The principal residence exemption extends to up to three appurtenant structures (pertinenze), one for each of the following cadastral categories:
- C/2 — Storage rooms, cellars, attics
- C/6 — Garages, parking spaces
- C/7 — Covered enclosures, canopies
This means your garage, cellar, and covered parking space can all be IMU-exempt alongside your main home.
Renovation and Building Bonus Deductions (Bonus Ristrutturazione)
Italy offers one of Europe's most generous renovation tax credit schemes. For 2025, the Bonus Ristrutturazione allows homeowners to deduct a percentage of eligible renovation costs from their IRPEF liability.
2025 Rates and Limits
For the 2025 tax year:
- Principal residence: 50% deduction on expenses up to EUR 96,000 per property unit
- Other properties (second homes, rental properties): 36% deduction on expenses up to EUR 96,000
Starting from 2026 and 2027, the rates are scheduled to decrease:
- Principal residence: 36% (up to EUR 96,000)
- Other properties: 30% (up to EUR 96,000)
The deduction is spread equally over 10 annual installments in your income tax return.
Eligible Renovation Works
Eligible works include:
- Extraordinary maintenance (e.g., roof replacement, structural repairs)
- Restoration and rehabilitation of the building
- Installation of security systems (alarms, reinforced doors, CCTV)
- Removal of architectural barriers (accessibility improvements)
- Asbestos removal
- Measures to prevent break-ins
Common mistake: Ordinary maintenance (painting, minor plumbing fixes) on individual property units does not qualify — it only qualifies when performed on common areas of condominium buildings.
How to Claim
To claim the renovation bonus:
- Pay all expenses via bank transfer (bonifico parlante), specifying the fiscal code, VAT number of the contractor, and the relevant law reference.
- Retain all invoices and payment receipts.
- Report the expenses in your annual tax return (Modello 730 or Modello Redditi PF).
- For works exceeding EUR 70,000, ensure the contractor is compliant with the national collective labor agreement (CCNL).
Energy Efficiency Deductions (Ecobonus) in 2025/2026
The Ecobonus remains available in 2025, allowing property owners to deduct the cost of energy-efficiency improvements.
2025 Ecobonus Rates
| Type of Work | Principal Residence | Other Properties |
|---|---|---|
| Thermal insulation, high-efficiency boilers, solar panels | 50% | 36% |
| Heat pumps, biomass heating systems | 50% | 36% |
| Window and door replacements | 50% | 36% |
| Building envelope improvements | 50% | 36% |
Maximum spending limits vary by intervention type, ranging from EUR 30,000 (e.g., for boiler replacements) to EUR 100,000 (for comprehensive building envelope improvements).
For 2026–2027, rates drop to 36% for principal residences and 30% for other properties.
Superbonus: What Remains in 2025?
The once-headline-grabbing Superbonus 110% has been progressively scaled back. For 2025:
- The Superbonus rate is reduced to 65%.
- Only projects that had filed the appropriate building permits (CILA-S) by October 15, 2024 remain eligible.
- The invoice discount (sconto in fattura) and credit transfer (cessione del credito) options have been largely eliminated for new projects, with limited exceptions for social housing (IACP) and earthquake-affected areas.
In practice, most new property improvements in 2025 will fall under the standard Ecobonus or Bonus Ristrutturazione rather than the Superbonus.
Mortgage Interest Deduction and Other IRPEF Deductions
If you purchased your principal residence with a mortgage, Italy offers a valuable income tax deduction on mortgage interest.
Mortgage Interest Deduction (Detrazione Interessi Mutuo)
- Deduction rate: 19% of mortgage interest and related charges
- Maximum eligible amount: EUR 4,000 per year (for principal residence purchase loans)
- Maximum tax saving: EUR 760 per year (19% × EUR 4,000)
This applies to mortgages taken to purchase or build the taxpayer's principal residence. Refinancing loans also qualify, provided the original purpose was principal residence acquisition.
Example: If you pay EUR 5,500 in mortgage interest during 2025, you can deduct 19% of the capped EUR 4,000 = EUR 760 from your IRPEF liability.

Real Estate Agency Fees
Buyers of a principal residence can deduct 19% of real estate agency commissions up to a maximum of EUR 1,000, yielding a maximum benefit of EUR 190.
Rental Deductions for Tenants
Tenants (not just owners) benefit from property-related deductions:
- Standard rental deduction: EUR 300 for incomes up to EUR 15,493.71; EUR 150 for incomes between EUR 15,493.71 and EUR 30,987.41
- Young tenants (aged 20–31): A deduction of EUR 991.60 or 20% of rent paid (whichever is higher, up to EUR 2,000) for the first four years of a rental contract, provided total income does not exceed EUR 15,493.71
Property Tax Relief for Non-Residents and Expats
Non-residents owning Italian property face a different tax landscape but still have access to important Italy tax relief measures.
IMU for Non-Residents
Since non-residents typically cannot establish residenza anagrafica in Italy, they generally cannot claim the principal residence IMU exemption. IMU is due at the full municipal rate on all properties.
However, there is one notable concession:
- Italian pensioners resident in an EU/EEA country or a country with a tax treaty with Italy: For one property owned in Italy (not rented or given in free loan), IMU is reduced by 50% provided the pensioner receives a pension from the Italian social security system.
Reduced IMU for Historical or Unusable Properties
Property owners — resident or non-resident — can claim a 50% reduction in the IMU tax base for:
- Properties of historical or artistic interest declared under Legislative Decree 42/2004
- Properties declared structurally unusable or uninhabitable (with certification from the municipality or a sworn technical report)
Double Taxation Treaties
Italy has an extensive network of double taxation agreements (over 90 treaties) that determine how property income and gains are taxed when the owner is resident in another country. Under most treaties following the OECD model, Italy retains the right to tax income from Italian real estate, but the taxpayer's country of residence must provide relief — usually through a foreign tax credit mechanism.
For example, a UK resident earning rental income from an Italian apartment will pay Italian tax on that income but can offset it against their UK tax liability under the Italy-UK tax treaty.
Tip for expats: Always check the specific treaty between Italy and your country of residence, as provisions vary. Some treaties include special clauses for capital gains on property sales.
Frequently Asked Questions (FAQ)
Is the principal residence IMU exemption automatic?
No. While you don't file a separate claim, you must ensure your registered residence (residenza anagrafica) matches the property address and that you actually live there. If you move or change your registered address, you must update the municipality — failure to do so can result in back-taxes and penalties.
Can I combine multiple renovation bonuses on the same property?
Yes, in many cases. For example, you can claim both the Bonus Ristrutturazione for structural work and the Ecobonus for energy-efficiency upgrades on the same property, provided the expenses relate to different types of work and you do not claim the same expenditure under two different schemes.
Do I need to pay property tax on inherited property in Italy?
Yes. Inherited property is subject to IMU from the date of inheritance. If you inherit a property and establish it as your principal residence, you can claim the exemption. Otherwise, IMU applies at the standard municipal rate.
What happens if I miss the IMU payment deadline?
IMU is paid in two installments: the advance payment by June 16 and the balance by December 16. Late payments incur interest (currently at the legal rate) and penalties starting at 0.1% per day for the first 14 days (ravvedimento operoso), escalating the longer the delay. Timely voluntary correction is always more favorable than waiting for an official assessment.
Are property improvements by non-residents eligible for renovation bonuses?
Yes. Non-residents who pay Italian income tax (IRPEF) on their property income can claim renovation and energy-efficiency bonuses. The deduction is applied against their Italian IRPEF liability. However, if the non-resident has little or no Italian taxable income, the practical benefit of the deduction may be limited since unused credits generally cannot be refunded.
Conclusion and Key Takeaways
Italy's property tax system for 2025/2026 offers substantial deductions and allowances for those who know where to look. Here are the essential points to remember:
- The principal residence IMU exemption is the most valuable allowance — ensure your registered and habitual residence match to claim it.
