Property Capital Gains Tax Calculator Italy 2026

Property capital gains (plusvalenza immobiliare) refers to the profit realized when you sell a property in Italy for more than you originally paid for it. Under Italian tax law, specifically Art. 67, paragraph 1, letter b) of the TUIR (Testo Unico delle Imposte sui Redditi, D.P.R. 917/1986 — the consolidated income tax code), capital gains from property sales are classified as "redditi diversi" (miscellaneous income). This category covers income that does not fall under the typical headings of employment income, business income, or investment income, but instead arises from speculative transactions or the sale of assets for consideration.

Importantly, capital gains tax on property does not apply to every profitable sale. Italian law provides that the gain is only taxable when the sale occurs within 5 years of purchase (or construction of the property). If you have owned the property for more than 5 years, any capital gain you realize is completely exempt from tax. This rule is based on the legislative assumption that a sale within a short holding period is speculative in nature, whereas a longer holding period represents a genuine long-term investment that the lawmaker does not intend to penalize. For expats buying property in Italy, this 5-year rule is one of the most critical tax planning considerations when deciding whether and when to sell.

There is another extremely important exemption: capital gains are never taxable if the property has been used as the seller's (or their family members') primary residence (abitazione principale) for the majority of the ownership period. This means that if you purchased an apartment, moved your official residence there (residenza anagrafica), and lived in it as your main home, selling it even within the 5-year window does not generate any taxable capital gain. The condition is that the property must have served as your primary residence for more than half the period between purchase and sale. For example, if you bought a property 3 years ago and lived in it for at least 18 months and one day, the capital gain is fully exempt. This exemption is particularly relevant for expats who register their Italian residency at the property they purchase.

How to calculate the capital gain: sale price minus purchase price minus documented costs

The calculation of property capital gains is governed by Art. 68 of the TUIR. The basic formula is straightforward: the capital gain equals the difference between the sale price received (corrispettivo percepito) and the original purchase price or construction cost of the property, increased by all documented incidental costs. In formula:

The deductible incidental costs that can be subtracted from the purchase price include: notary fees for the purchase deed (but not notary fees related to the mortgage contract), taxes paid at purchase (registration tax / imposta di registro, VAT / IVA if applicable, mortgage and cadastral taxes / imposte ipotecarie e catastali), real estate agency fees paid at purchase (documented by invoice), and renovation and improvement costs incurred during the ownership period (provided they are documented by invoices and paid via traceable methods such as bank transfer or credit card). Routine maintenance costs and undocumented expenses are not deductible.

It is essential to keep all receipts and invoices for the entire period you own the property, because every euro of documented cost reduces the taxable capital gain. In particular, renovation expenses can have a very significant impact: a documented renovation of 30,000 euros reduces the capital gain by the same amount, yielding a tax saving of 7,800 euros (at the 26% flat rate) or up to 12,900 euros (at the 43% top IRPEF bracket). For expats who renovate their Italian property, this is a powerful deduction that should not be overlooked.

The two options: standard IRPEF taxation vs 26% flat-rate substitute tax

A taxpayer who realizes a taxable property capital gain has the right to choose between two taxation regimes:

Standard IRPEF taxation: the capital gain is declared in the RL section of the Modello Redditi PF (or the D section of Modello 730) and is added to the taxpayer's total taxable income. It is then taxed according to the progressive IRPEF tax brackets in force for 2026: 23% on income up to 28,000 euros, 33% on income from 28,001 to 50,000 euros, and 43% on income above 50,000 euros. Regional and municipal surcharges (addizionali) are added on top. The practical effect is that the capital gain is "stacked" on your ordinary income (salary, pension, etc.) and taxed at your marginal rate. For expats with moderate Italian income, this option can sometimes be advantageous.

26% flat-rate substitute tax (imposta sostitutiva): alternatively, the taxpayer can request the notary at the time of the sale to apply a fixed 26% flat-rate tax on the capital gain. This option is provided by Art. 1, paragraph 496, of Law 266/2005 and subsequent amendments. The tax is paid by the notary at the time the deed is registered and has a final, liberating character: the capital gain does not need to be declared in the annual tax return. This "pay and forget" simplicity makes it an attractive choice for many property sellers, especially those unfamiliar with the Italian tax return process.

When the flat-rate substitute tax is more convenient

The choice between the two options depends entirely on the taxpayer's marginal IRPEF rate. The reasoning is straightforward: the substitute tax is beneficial when your marginal IRPEF rate exceeds 26%. In practice:

If your marginal rate is 23% (income up to 28,000 euros), standard taxation is cheaper, because you pay less than 26%. If your marginal rate is 33% (income between 28,001 and 50,000 euros) or 43% (income above 50,000 euros), the 26% flat-rate tax is more advantageous. However, an important nuance must be considered: under standard taxation, the capital gain is added to your income and may push you into a higher bracket. A taxpayer earning 25,000 euros who realizes a 30,000 euro capital gain would see part of it taxed at 23% and part at 33%. In such cases, the calculation must account for this cumulative bracket effect. Our calculator uses the marginal rate as a simplified reference, but for complex situations it is advisable to consult a commercialista (Italian tax accountant).

You should also factor in the IRPEF surcharges (regional and municipal addizionali), which apply only under standard taxation and not with the substitute tax. These can add approximately 1.5% to 4% depending on your region and municipality of residence, potentially making the substitute tax more convenient even for taxpayers in the 23% marginal bracket if their local surcharges are particularly high. As an expat, checking the surcharge rates for the specific comune where you are registered is an important step.

Deductible costs: notary, agency fees, registration tax, documented renovations

Correctly identifying all deductible costs is essential to minimizing your taxable capital gain. The main costs that can be subtracted from the purchase price are:

Notary fees for the property purchase deed (atto di compravendita). However, notary fees related to the mortgage contract (atto di mutuo) cannot be deducted for capital gains purposes.

Taxes paid at purchase: registration tax (imposta di registro), typically 2% of the cadastral value for a primary residence or 9% for second homes; mortgage and cadastral taxes (imposte ipotecarie e catastali), 50 euros each for primary residences, or 1% and 2% respectively for second homes purchased from a private seller. If the purchase was from a developer and subject to VAT (IVA), the VAT paid (4% for primary residence, 10% for second homes) is also deductible.

Real estate agency fees paid at purchase, provided they are documented by invoice. Agency commissions paid at the time of sale are not deductible from the capital gain (though they may qualify for a 19% tax credit in the tax return for primary residence purchases, up to a maximum of 1,000 euros).

Renovation and improvement costs: all expenses for building works on the property during the ownership period, provided they are documented by invoices and paid via traceable instruments (bank transfer, credit/debit card). This includes extraordinary maintenance, renovation, extension, and any work that increased the property's value. Routine maintenance costs (minor repairs, interior painting) are generally not deductible. For expats who have invested in renovating an Italian property, systematically retaining all invoices paid by bonifico bancario is critical for tax optimization at the time of sale.

Inherited property: always exempt from capital gains tax

For properties acquired through inheritance (successione ereditaria), Art. 67, paragraph 1, letter b) of the TUIR provides a complete exemption from capital gains tax. The sale of an inherited property never generates a taxable capital gain, regardless of how much time has passed since the inheritance and regardless of the sale price. This exemption exists because the lawmaker considers that acquisition by inheritance is not speculative in nature.

It is important to distinguish this situation from that of a donation (donazione), which follows different rules (see the next section). The favorable treatment of inheritance is one of the reasons why many Italian families prefer the transmission of property upon death (mortis causa) rather than inter vivos donation. For expats who have inherited property in Italy from Italian relatives, this is a significant tax advantage worth knowing about.

Donated property: the acquisition cost is what the donor originally paid

For properties acquired through donation (donazione), the situation is more complex and often less favorable. Art. 68 of the TUIR establishes that when a donated property is sold, the capital gain is calculated using the cost originally paid by the donor as the purchase price (i.e., what the donor paid to acquire the property), increased by the documented incidental costs of both the donor and the donee. Furthermore, the 5-year exemption period is counted from the donor's original purchase date, not from the date of the donation.

Here is an example: a father buys a property in 2020 for 150,000 euros. In 2024 he donates it to his son. The son sells it in 2026 for 250,000 euros. The ownership period is calculated from 2020 (the father's purchase): that is 6 years, so the capital gain is exempt. However, if the father had purchased in 2022, the 5-year period would not yet have elapsed, and the son would need to pay tax on a capital gain of 100,000 euros (250,000 minus 150,000), reduced by any documented costs. This "backdating" rule is especially important for expats to consider when planning intergenerational property transfers.

Worked example: purchase at 200,000 euros in 2023, sale at 280,000 euros in 2026

Let us consider the case of James, an expat who bought an apartment in 2023 for 200,000 euros as an investment (not as his primary residence). At the time of purchase he incurred the following costs: notary fees 3,000 euros, real estate agency 5,000 euros, registration tax and mortgage/cadastral taxes 7,000 euros. Total purchase costs: 15,000 euros. During ownership he carried out a bathroom and kitchen renovation for 10,000 euros (documented by invoices and paid by bank transfer).

In 2026, James sells the property for 280,000 euros. His holding period is 3 years (2023–2026), which is less than the 5-year exemption threshold. The taxable capital gain is:

James has a gross annual salary (RAL) of 40,000 euros, placing him in the 33% marginal IRPEF bracket. Let us compare the two options:

Flat-rate substitute tax (26%): 55,000 x 26% = 14,300 euros. Net proceeds from the sale: 280,000 − 14,300 = 265,700 euros.

Standard IRPEF taxation (33% marginal rate): the capital gain is added to his income. With a RAL of 40,000 euros plus the 55,000 euro capital gain, part of the gain would fall in the 43% bracket (above 50,000 euros of total income). Approximately: 10,000 euros at 33% (up to the 50,000 euro threshold) + 45,000 euros at 43% = 3,300 + 19,350 = 22,650 euros, plus regional and municipal surcharges. Net proceeds from the sale: approximately 257,350 euros.

For James, the 26% flat-rate substitute tax is clearly more advantageous, yielding a saving of approximately 8,350 euros. The difference becomes even more pronounced when regional and municipal surcharges (which apply only under standard taxation) are factored in. This example illustrates why running the numbers before visiting the notary is so important.

The table below summarizes the applicable tax rates for property capital gains and the main legal references for 2026.

Taxes paid at purchase — typical amounts

The first table clearly shows that the 26% flat-rate substitute tax is advantageous for anyone with a marginal IRPEF rate of 33% or higher. For taxpayers in the lowest bracket (23%), standard taxation is slightly less expensive, although the difference shrinks when regional and municipal surcharges (which can add roughly 2% to 3.5%) are taken into account. The second table helps you estimate the purchase taxes you can deduct from the capital gain. All of these taxes paid at acquisition are fully deductible from the sale proceeds when computing the taxable gain. The recommendation is to carefully evaluate your overall tax situation before making a choice, ideally with the assistance of a qualified commercialista.
