Filing your tax return is a crucial annual event for every taxpayer. Among the various schedules that make up Form 730, Schedule E is particularly important for those who have taken out a mortgage to purchase their primary residence. Filling out this section carefully and accurately allows you to access significant tax deductions, lightening your tax burden and optimizing your financial situation. Understanding the rules, limits, and correct procedures for reporting mortgage interest and ancillary charges is essential to avoid missing out on a major savings opportunity.
This guide was created to provide clear, practical instructions for navigating Schedule E, with a specific focus on line E7, which is dedicated to mortgage interest. We will cover various scenarios, from eligible to excluded expenses, analyzing the requirements under Italian law. In an ever-evolving European economic context, where personal financial stability is a priority, taking advantage of every available tax benefit becomes a strategic choice. Combining the tradition of homeownership, so deeply rooted in Mediterranean culture, with the innovation of digital tax tools like the pre-filled Form 730, is the key to managing your finances wisely.

Schedule E of Form 730: The Heart of Deductions
Schedule E of Form 730 is the section for declaring charges and expenses that entitle you to a tax deduction or an income deduction. Tax deductions, like those for mortgage interest, are applied directly to the gross tax, reducing the final amount due. Income deductions, on the other hand, lower the total taxable income on which the tax is calculated. It is essential to distinguish between these two types of benefits to apply them correctly. Within this schedule, Section I is of greatest interest to borrowers, as it includes expenses eligible for a 19% tax deduction, including interest on a mortgage for the purchase of a primary home.
Reporting these expenses correctly is crucial. An error or omission can result in the loss of the tax benefit. Fortunately, the pre-filled Form 730, available on the Italian Revenue Agency’s website, already contains much of this information, transmitted directly by lending institutions. However, it is always the taxpayer’s responsibility to verify the accuracy and completeness of the reported data, adding to or modifying it if necessary. This review step is essential to ensure you have included all deductible expenses incurred during the relevant tax year.
Focus on Line E7: How to Deduct Mortgage Interest
Line E7 is the specific field in Schedule E where you must enter the interest, ancillary charges, and revaluation amounts paid on mortgage loans taken out to purchase a primary residence. A “primary residence” is the property where the taxpayer or their family members (spouse, relatives up to the third degree, and in-laws up to the second degree) habitually reside and have their registered residence. The eligible IRPEF deduction is 19% of the expenses incurred, calculated on a maximum amount of €4,000 for each mortgage holder. This means a single taxpayer can get a maximum refund of €760 (19% of €4,000).
Filling out line E7 requires care. You must report the total amount of interest and other ancillary charges paid during the year, regardless of the payment due dates (the so-called cash basis principle applies). The annual statement issued by the bank is the key document that summarizes the exact amount to report on your tax return. In the case of a joint mortgage, the €4,000 limit is divided among the joint holders, usually in equal parts. For example, two spouses who are joint holders can each deduct 19% on a maximum of €2,000.
Eligible Expenses for Deduction: More Than Just Interest
In addition to interest, which is the main expense item, tax regulations also allow for the deduction of a series of ancillary charges related to securing the mortgage contract. These expenses, when added to the interest, count toward the €4,000 maximum limit. It’s important to know what they are to maximize your tax benefit. Deductible ancillary charges include the notary fees for the mortgage contract (but not for the property purchase agreement), appraisal and loan processing fees, and the substitute tax applied to the loan principal.
Furthermore, commissions paid to lending institutions for their brokerage services are also deductible. The documentation you need to keep to prove these expenses includes the notary’s invoices and receipts for payments made. An important point to note is that, since 2020, to qualify for the deduction, payments must be traceable, meaning they must be made via bank transfer, postal order, or other electronic payment systems. Payment receipts for installments and the bank’s statement are considered valid proof of traceability.
What You Cannot Deduct: Important Exclusions
It is just as important to know which expenses, although related to the home purchase and mortgage, are not eligible for deduction. One of the most common exclusions is the notary fee for the property purchase agreement; only notary fees related to the mortgage contract are deductible. Likewise, you cannot deduct taxes related to the property transfer, such as the registration tax, VAT, and mortgage and cadastral taxes.
Another frequently excluded expense is the cost of insurance policy premiums on the property, such as fire and explosion insurance, even if required by the bank to grant the loan. The reason is that they are not considered strictly necessary for securing the mortgage contract itself. Finally, fees for collecting individual mortgage installments, a cost the bank charges for managing periodic payments, are not deductible. Understanding this distinction is crucial to avoid including non-eligible costs and facing subsequent adjustments from the Italian Revenue Agency.
Conditions and Requirements to Access the Benefit
To benefit from the mortgage interest deduction, you must meet specific conditions. The main one is that the purchased property must be designated as your primary residence within one year of the purchase date. In turn, the purchase must occur in the year before or after the mortgage is secured. This means you have a two-year “window” to complete the entire process: secure the mortgage, purchase the property, and establish residency there. Failure to meet these deadlines can result in losing the right to the deduction.
The deduction is available to the property buyer who is also the holder of the mortgage contract. However, there are exceptions. For example, if you relocate for work, you do not lose the right to the deduction even if you move your residence from the primary home. Also, in the case of a legal separation, the spouse who has left the property can continue to benefit from the deduction until the divorce decree is final, provided they were an owner and joint holder of the mortgage. To learn more about how different employment situations affect a bank’s assessment, it may be helpful to consult the guide on employment contracts and mortgages.
Special Cases: Construction, Renovation, and Refinancing
The interest deduction applies not only to mortgages for purchasing a primary home but also to those for its construction or renovation. In these cases, the deduction is available on a maximum amount of €2,582.28, and the taxpayer must designate the property as their primary residence within two years of the work’s completion. For these types of mortgages, specific codes are used on lines E8 to E10 of Form 730. For example, code 10 is used for mortgages taken out from 1998 to 2021, while code 46 is for those contracted from January 1, 2022.
Another common scenario is mortgage refinancing (known as ‘surroga’). When you transfer your mortgage from one bank to another to get better terms, you do not lose the right to the deduction. However, the tax benefit is calculated on the remaining principal balance of the original mortgage, plus any ancillary charges related to the refinancing transaction. In practice, you cannot deduct interest on an amount greater than what you would have been entitled to with the old loan. For those considering this option, the guide to choosing between refinancing and renegotiation can offer valuable insights.
Required Documentation: What to Keep
To take advantage of tax deductions and be prepared for any audits by the Italian Revenue Agency, it is essential to carefully keep all documentation related to the mortgage and the property purchase. The first document to save is the mortgage contract, which shows that the loan was granted for the purchase of the primary residence. The property purchase agreement is equally important.
Each year, the bank sends a statement that summarizes the interest and ancillary charges paid, along with the remaining principal balance. This is the reference document for filling out Form 730. You must also keep the notary’s invoices for securing the mortgage contract and the payment receipts for appraisal and processing fees. All these documents, which prove the expenses incurred, must be kept for the period required by law for potential tax audits. Proper record-keeping is a good habit that provides peace of mind and security.
Conclusion

Filling out Schedule E of Form 730 for the mortgage interest deduction is a task that requires attention and knowledge of current regulations. Although it may seem complex, being well-informed can turn this tax obligation into a real savings opportunity. From line E7 for a primary home purchase to the specific codes for renovations and construction, every detail is crucial for maximizing the 19% IRPEF benefit. Remembering the spending limits, like the €4,000 for a purchase, and the types of deductible ancillary charges is the first step toward a beneficial tax return.
In a landscape where the tradition of home buying meets the innovation of digital tools like the pre-filled Form 730, being an informed taxpayer makes all the difference. Always verifying the data provided by the Italian Revenue Agency and meticulously keeping all documentation, from the mortgage contract to invoices for ancillary charges, is not just an obligation but a way to protect your investment. Taking full advantage of tax benefits, like those described in our general guide to mortgage tax benefits, means managing your finances intelligently and lightening the burden of one of the most significant financial commitments in a person’s life.

This limit applies to mortgages for the purchase of a primary residence taken out on or after January 1, 2001.
In the case of a joint mortgage, the €4,000 expense limit must be divided among the joint holders. For example, if the mortgage is held 50/50 by two spouses, each can deduct 19% on a maximum amount of €2,000.

However, you may still be eligible for the deduction if, despite having moved, your family members (such as a spouse, relatives up to the third degree, and in-laws up to the second degree) continue to live in the property. There are also specific exceptions, for example, for those who relocate for work.
To claim the deduction, it is essential to keep certain documents to present in case of an audit by the Italian Revenue Agency. The main documents are: a copy of the property purchase agreement, a copy of the mortgage contract, payment receipts or the annual statement from the bank certifying the interest paid, and invoices for ancillary charges, such as the notary’s fees for securing the mortgage.
