Paying off a mortgage is a significant milestone for any homeowner, a moment that symbolizes the end of a long financial commitment and the beginning of a new phase of economic freedom. In Italy, a country with a strong homeownership culture and a solid tradition of property possession, this event holds special significance. However, once the last candle on the debt cake is blown out, a crucial question naturally arises: what happens to the tax deduction for interest payments? This benefit, which for years has lightened the tax burden for many taxpayers, doesn’t just vanish when the contract ends. Instead, it follows specific rules that are essential to know so you don’t miss out on the last opportunities for savings.
Italian tax law allows for a 19% deduction from IRPEF (Italian personal income tax) on interest and ancillary charges paid for mortgages taken out to purchase a primary residence. This benefit, however, is strictly tied to the existence of the debt. Once the mortgage is paid off, the interest payments cease, and consequently, so does the right to the deduction for future years. The issue, therefore, centers on the final tax return filed after the mortgage is paid off. It’s essential to understand how to correctly handle this last window of opportunity to maximize the tax benefit, in compliance with current regulations.
The Cash Basis Principle and the Final Deduction
For deducting mortgage interest, the Italian tax system is based on the cash basis principle. This means that expenses are deductible in the year they are actually paid, regardless of the accounting period they relate to. Therefore, if a mortgage is paid off, for example, in June 2025, the taxpayer will have the right to deduct all interest and ancillary charges paid from January 1st up to the payoff date on their 2026 tax return (for the 2025 tax year). This right also applies in the case of early mortgage payoff.
It is therefore crucial to carefully keep all documentation issued by the bank at the time of payoff. The lending institution will provide a final statement summarizing the total amount of interest paid in the final year. This document will be the key attachment for completing the Form 730 or the Redditi Persone Fisiche Form, certifying the last deductible amount. From the tax year following the one in which the mortgage was paid off, since there are no more interest payments, it will no longer be possible to claim any deduction related to that mortgage.
The Maximum Deductibility Limit
Even for the final year of payments, the deduction for interest on a mortgage for a primary residence is subject to a maximum spending cap. The law states that the 19% deduction is calculated on a maximum amount of €4,000. This limit is all-inclusive and refers to the total interest and ancillary charges paid during the fiscal year, up to the day of the payoff. It’s important to note that the €4,000 limit is per taxpayer and per property, and it is not prorated based on the number of months the mortgage was active during the year.
In the case of a joint mortgage, the maximum limit of €4,000 must be divided among the joint holders based on their ownership share and their share of the mortgage. For example, for two spouses who are 50/50 joint holders, each can deduct 19% on a maximum amount of €2,000. If one of the spouses is a tax dependent of the other, the latter can claim the deduction for both shares, still respecting the overall limit of €4,000.
Special Cases: Refinancing and Payoff with a New Loan
The life of a mortgage can be complex and not always straightforward. Situations like mortgage refinancing or replacement have their own specific rules, even when it comes to the final payoff. If you pay off one mortgage to take out a new one, for example, through refinancing or replacement, the right to the deduction transfers to the new loan. However, the basis for calculating the deduction cannot exceed the remaining principal of the original mortgage.
This principle aims to prevent taxpayers from benefiting from a larger deduction simply by changing contracts. The continuity of the tax benefit is guaranteed, but only within the limits of the original debt taken out to purchase the primary residence. Even in these scenarios, once the new mortgage (which replaced the old one) is paid off, the same rules apply: the deduction ceases with the last interest payment, which must be declared the following year according to the cash basis principle.
Ancillary Charges and Prepayment Penalties
In addition to interest, a series of ancillary charges related to obtaining the mortgage can also be deducted. These include, for example, loan origination fees, appraisal fees, notary fees for the mortgage deed, and the substitute tax. A common question concerns the deductibility of any early prepayment penalties. For mortgages taken out after February 2, 2007 (under the Bersani Law), there are no penalties for the early payoff of mortgages for the purchase or renovation of properties used as a residence or for conducting business or professional activities.
For contracts prior to that date, if a penalty was stipulated, the law considers it a deductible ancillary charge. Therefore, the amount paid as a penalty for early mortgage payoff can be added to the interest paid during the year and contribute to reaching the maximum limit of €4,000. This represents a small but significant tax recovery at the close of the relationship with the bank.
Conclusions
Paying off a mortgage is a moment of great satisfaction that closes an important chapter in a family’s financial life. While it marks the end of the debt, it also means the end of a significant tax benefit like the deduction for interest payments. The fundamental rule to remember is the cash basis principle: you are entitled to one final deduction in the fiscal year you actually paid off the loan, deducting all interest paid up to that point. It is crucial to keep the final certification from the bank to correctly document the expense on the subsequent tax return.
Understanding these dynamics allows you to manage the final act of your mortgage with awareness and precision, without missing the opportunity to recover a portion of the expenses incurred. Although the tax advantage ends, the financial freedom gained by paying off the debt is the real, great gain—a milestone that combines tradition and innovation in managing family assets within the Italian and European cultural context.

Frequently Asked Questions
No, the deduction for mortgage interest is no longer possible for the year following the payoff. The right to the deduction is based on the cash basis principle: you can only deduct the interest actually paid during the fiscal year. Consequently, on the tax return for the year after the payoff, there will be no interest to deduct.
If you pay off a mortgage and take out a new one (including through refinancing or renegotiation), you can continue to benefit from the tax deduction. However, the deduction is calculated on the remaining principal balance of the old mortgage. If the new loan has a higher amount, you can only deduct interest on the portion of the principal that corresponds to the remaining debt of the previous mortgage, plus any ancillary costs for the transaction.
On the last applicable tax return, the one for the year you paid off the mortgage, you can deduct all interest paid up to the payoff date. In addition to interest, you can also include ancillary charges incurred during the year, such as an early prepayment penalty, if stipulated in the contract. Remember that the maximum deductible amount is always €4,000 per year for mortgages on a primary residence.
The deduction is calculated on the amount of interest and ancillary charges you actually paid during the year, up to the time of payoff. You will add up the amounts from all the installments paid in that year and apply the 19% deduction to this sum, respecting the maximum cap of €4,000. The bank will provide you with an annual statement showing the total interest paid.
Yes, it is essential to keep all documentation even after paying off the mortgage. For the final return on which you claim the deduction, you must keep the payment receipts for the installments, the annual bank statement certifying the interest paid, and the mortgage payoff deed. These documents are necessary in case of an audit by the Agenzia delle Entrate (Italian Revenue Agency).
