Buying a home with a mortgage is a fundamental step in the lives of many Italians, an investment that intertwines personal dreams and future stability. In a country like Italy, where the home is a pillar of Mediterranean culture and a symbol of family tradition, understanding the tax aspects related to this commitment is crucial. Italian tax law offers several benefits for those who take out a mortgage for their primary residence, but navigating the deductions, charges, and requirements can be complex. This guide aims to provide clarity, offering a comprehensive and up-to-date overview of the tax benefits available in 2025, to turn a financial burden into a savings opportunity.

Navigating the tax system requires attention and knowledge. From the well-known deduction for mortgage interest to the incidental expenses that can be claimed, every element helps to lighten the economic burden of the mortgage. The goal is to provide practical tools and clear information, suitable for both those entering the real estate market for the first time and those who already have experience but are looking to optimize their tax situation. A thorough understanding of these dynamics means not only complying with legal obligations but also seizing all the opportunities that legislative innovation provides, in a perfect balance between tradition and modernity.

Understanding Mortgage Tax Deductions

The main tax advantage for those who take out a mortgage to purchase their first home is the 19% IRPEF deduction on interest payments and incidental charges. This means that a portion of the annual expenses for the mortgage can be subtracted from the gross tax owed, thus reducing the amount to be paid to the state. It is a mechanism designed to support families and individuals in purchasing their primary residence, an asset considered central to Italian social and economic culture. The legislation, despite various changes over time, maintains this core principle.

To benefit from this tax break, the mortgage must be a mortgage loan (mutuo ipotecario) and be intended for the purchase, construction, or renovation of the property that will become the primary residence of the taxpayer or their family members. Understanding these requirements is the first step to properly planning your real estate investment and maximizing tax benefits, an aspect that combines traditional prudence with the need to innovate personal financial strategies.

Deducting Mortgage Interest

The core of the tax benefit lies in the deduction of mortgage interest (interessi passivi), which is the portion of each payment that compensates the bank for the loaned capital. Italian law allows for a 19% deduction on this interest, calculated on a maximum amount of €4,000 per year. Consequently, the maximum tax savings obtainable for each tax year is €760. This limit applies to the total amount of interest paid, regardless of the number of contract holders.

It is essential that the mortgage holder is also the owner of the property. In the case of a joint mortgage, each holder can deduct their share of the interest, always respecting the overall limit. For example, two spouses with a joint mortgage can each deduct up to €2,000 of interest. Only if one spouse is a tax dependent of the other can the latter benefit from the deduction for both shares. Proper management of these aspects is essential, and for this, consulting a complete guide to a first-home mortgage can be useful.

Who Can Benefit from the Deduction

To access the tax deduction, specific requirements must be met. The first and most important is that the purchased property becomes the primary residence within one year from the date of the deed. A primary residence is defined as the one where the taxpayer or their family members habitually reside. If this requirement is not met, for example, by leaving the property vacant or renting it out, the right to the benefit is lost. There are exceptions, such as moving for work-related reasons, which do not cause the loss of the tax break.

Furthermore, the purchase of the property must occur in the year preceding or following the signing of the mortgage contract. The regulations provide different conditions depending on the mortgage signing date, with specific rules for contracts predating 2001. It is crucial to keep all documentation, such as the purchase deed and the mortgage contract, to prove eligibility when filing tax returns. The bank plays a key role, as it is required to issue an annual certification stating the amount of interest paid.

How to Calculate the Applicable Deduction

Calculating the mortgage tax deduction is an operation that requires attention to detail. The calculation is based on the mortgage interest and incidental charges paid during the tax year, up to the maximum cap of €4,000. The 19% IRPEF rate is applied to this amount. If the total amount of interest and charges exceeds €4,000, the deduction will still be calculated on this maximum figure, resulting in a saving of €760. If, however, the expense is lower, the deduction will be 19% of the amount actually paid.

An important aspect to consider is the ratio between the purchase cost of the property and the borrowed capital. If the mortgage amount exceeds the property’s purchase cost (including incidental charges), the deductible interest must be proportionally recalculated. For example, if you buy a house for €150,000 but get a €200,000 mortgage, the deductible interest will be reduced by 25%. This rule ensures that the tax benefit is strictly linked to the first-home investment. For a precise estimate, using an online mortgage simulator can help in planning expenses.

Finally, it is important to be aware of tax updates that may affect the calculation. For 2025, the Budget Law introduced a flat-rate cut of €260 on the total amount of 19% deductions for taxpayers with a total income exceeding €50,000. This measure also affects mortgage interest and must be considered when calculating the final net benefit.

Deductible Incidental Expenses

In addition to mortgage interest, tax law also allows for the deduction of a series of incidental charges related to the signing of the mortgage contract. These expenses, incurred as a one-time cost when the loan is taken out, contribute to the €4,000 maximum cap in the first year. This category includes various cost items that, when added up, can have a significant impact.

Among the main deductible incidental expenses are: the notary’s fee for the mortgage contract (but not for the purchase deed), technical appraisal fees for the property valuation, and loan-related taxes, such as the substitute tax or the tax for mortgage registration and cancellation. Commissions paid to banking intermediaries for their brokerage services are also included. It is essential to keep all invoices and receipts for traceable payments to document these expenses when filing tax returns.

Taxes on the Mortgage Deed

When you take out a mortgage with a bank for a term longer than 18 months, you are subject to a preferential tax regime that involves paying a substitute tax. This tax, as the name suggests, replaces a series of other taxes that would otherwise be due, such as registration tax, stamp duty, and mortgage and cadastral taxes on the loan agreement. The rate varies depending on the purpose of the mortgage. For the purchase, construction, or renovation of a “first home,” the rate is 0.25% of the loan amount disbursed.

If the mortgage is for the purchase of a home that does not qualify as a “first home,” the substitute tax rate increases to 2%. The bank acts as a withholding agent, deducting the amount due directly from the sum disbursed to the borrower and paying it to the Treasury. This mechanism simplifies the procedure for the taxpayer. It is important to verify that the mortgage contract expressly indicates the option for this advantageous tax regime. To learn more about the differences between various types of financing, it may be useful to read a guide on mortgage vs. unsecured loans.

Tradition and Innovation in the Italian Context

The concept of a “first home” is deeply rooted in Mediterranean culture, representing not just a material asset but a life project, a place of stability and tradition. The Italian tax system, with its benefits, recognizes and supports this social value. The deduction for mortgage interest is an example of how economic policy intertwines with citizens’ aspirations, facilitating a journey that for many is the biggest investment of their lives. This tradition of support is constantly renewed through legislative innovation, seeking to adapt to market changes and the new needs of families.

Innovation is also evident in the ways taxpayers can access benefits. The digitalization of Public Administration, with the pre-filled Modello 730, simplifies the declaration of mortgage-related data, making benefits more accessible. At the same time, new forms of financing such as green mortgages, designed for energy-efficient homes, introduce further tax advantages, combining the dream of homeownership with a growing awareness of environmental sustainability. This balance between the traditional value of the home and innovation in fiscal and financial policies defines the current mortgage landscape in Italy.

Tackling the purchase of a home with a mortgage is a complex journey where financial aspects merge with tax-related ones. A thorough knowledge of the available deductions and benefits is essential to optimize your investment and lighten the economic burden. The 19% IRPEF deduction on mortgage interest and incidental charges, with a cap of €4,000, represents the main savings tool for those purchasing a primary residence. It is essential to meet all requirements, such as designating the property as a primary residence within one year, and to meticulously keep all necessary documentation.

The Italian tax system, despite its complexity, offers concrete support for the value of homeownership, a pillar of the culture and society. The ever-evolving regulations seek to balance tradition and innovation, introducing new features such as changes for higher incomes or benefits for energy efficiency. Staying constantly informed and planning carefully allows you to navigate this landscape with confidence, turning tax obligations into conscious opportunities. Prudent management of your mortgage, supported by a solid understanding of the rules, is the key to achieving the dream of homeownership in a serene and advantageous way.

Frequently Asked Questions

What exactly can I deduct for a first-home mortgage?

You can deduct 19% of the mortgage interest and incidental charges paid on a mortgage loan for the purchase of a primary residence from your IRPEF (personal income tax). It is important to note that the deduction applies only to the interest portion and not to the principal repayment. Deductible incidental charges include, for example, loan origination fees, appraisal fees, notary fees for the mortgage deed, and the substitute tax.

What is the maximum amount I can deduct each year?

The maximum expense on which you can calculate the 19% deduction is €4,000 per year. This means the maximum tax saving you can achieve is €760 (19% of €4,000). If the interest paid in a year is less than €4,000, the deduction will be calculated on the amount actually paid.

How does the deduction work if the mortgage is jointly held?

If the mortgage is jointly held, the €4,000 limit is divided among the joint holders according to their share. For example, with two joint holders at 50% each, each can deduct 19% on a maximum of €2,000 in interest. To be eligible for the deduction, each joint holder must also be an owner of the property. An exception applies if one spouse is a tax dependent of the other; in that case, the spouse filing the return can also deduct the dependent spouse’s share.

What documents do I need to keep for my tax return (Modello 730)?

To benefit from the deduction, it is essential to keep several documents: the mortgage contract, the property purchase deed (rogito notarile), payment receipts for the installments or the annual certification from the bank summarizing the interest paid, and invoices for incidental charges (like the notary’s invoice for the mortgage deed). Although it is not necessary to attach them to the Modello 730, they must be presented in case of an audit by the Agenzia delle Entrate (Italian Revenue Agency).

Do I lose the deduction if I move or rent out my ‘first home’?

Yes, as a rule, you lose the right to the deduction starting from the year after the property is no longer used as a primary residence. However, there are exceptions: the right to the deduction is not lost in case of a move for work-related reasons or permanent admission to a nursing home, provided the house is not rented out. If you later return to reside in the property, you can resume taking the deduction for installments paid from that point forward.
