Capital gains on real estate is a topic that concerns anyone selling a property at a price higher than the purchase price. Understanding when a capital gain is taxable, how to calculate it, and what legal strategies exist to reduce its tax impact is essential for properly planning a property transaction. In this guide, we analyze the 2026 regulations in detail, with practical calculation examples and all the exemption cases provided by law.
What Is a Real Estate Capital Gain
A real estate capital gain is the economic profit realized when a property is sold at a price higher than the purchase (or construction) cost. From a tax perspective, it is governed by Article 67 of the TUIR (Consolidated Income Tax Act) and falls under "miscellaneous income."
In simple terms:
Capital Gain = Sale Price - Purchase Cost - Deductible Costs
Not all real estate capital gains are subject to taxation. The law provides specific time-based and usage conditions that determine whether or not the realized gain is taxable.
When Is the Capital Gains Tax Payable
The real estate capital gain is taxable in the following cases:
- Sale within 5 years of purchase: if the property is sold for consideration within 5 years of the date of purchase (or construction), the capital gain is subject to taxation
- Property not used as primary residence: if the property sold was not used as the primary residence of the seller or their family members for the majority of the ownership period
- Building land: capital gains on building land are always taxable, regardless of the ownership period
Cumulative Conditions
For the sale of buildings (not land), the capital gain is taxable only if both conditions are met simultaneously:
- The sale occurs within 5 years of purchase
- The property was not used as a primary residence for the majority of the ownership period
The 5-Year Exemption and Primary Residence
The 5-Year Rule
If a property is sold more than 5 years after the date of purchase (the date of the notarial deed applies), the capital gain is not taxable, regardless of the size of the gain realized. This rule applies to both properties purchased for consideration and those constructed.
Primary Residence Exemption
The capital gain is not taxable (even within the 5 years) if the property was used as the primary residence of the seller or their family members for the majority of the period between purchase and sale. "Majority" means more than half of the ownership period.
Example: if a property is purchased on January 1, 2024, and sold on January 1, 2026 (2 years of ownership), it is sufficient to have lived there for more than 1 year to benefit from the exemption.
How to Calculate the Capital Gain: Deductible Costs
The calculation of the capital gain is not simply based on the difference between the sale price and the purchase price. The law allows various costs incurred to be deducted, thus reducing the tax base:
Always Deductible Costs
| Type of Cost | Example | Notes |
|---|---|---|
| Purchase price | 200,000 EUR | As stated in the notarial deed |
| Registration tax or VAT | 18,000 EUR | Paid at the time of purchase |
| Notary fees at purchase | 3,500 EUR | Notary's fee + ancillary expenses |
| Brokerage fees (purchase) | 5,000 EUR | Real estate agent's commission |
| Renovation costs | 30,000 EUR | Only if documented with invoices and properly authorized |
| Improvement costs | 15,000 EUR | Works that increased the property's value |
Complete Calculation Example
Sale of an apartment purchased 3 years ago:
- Sale price: 280,000 EUR
- Purchase price: 200,000 EUR
- Registration tax paid: 18,000 EUR
- Notary fees: 3,500 EUR
- Agency commission (purchase): 5,000 EUR
- Documented renovation: 20,000 EUR
Calculation:
- Total purchase cost: 200,000 + 18,000 + 3,500 + 5,000 + 20,000 = 246,500 EUR
- Taxable capital gain: 280,000 - 246,500 = 33,500 EUR
26% Substitute Tax vs. Standard Income Tax (IRPEF)
Anyone who realizes a taxable real estate capital gain can choose between two taxation regimes:
Option 1: 26% Substitute Tax
The seller can request the notary, at the time of the sale, to apply a 26% substitute tax on the capital gain. This option is advantageous for those with medium-to-high incomes.
In the previous example: 33,500 x 26% = 8,710 EUR in tax
Option 2: Standard Income Tax (IRPEF)
The capital gain is added to the taxpayer's other income and taxed at progressive IRPEF rates:
| Income Bracket | IRPEF Rate 2026 |
|---|---|
| Up to 28,000 EUR | 23% |
| From 28,001 to 50,000 EUR | 35% |
| Over 50,000 EUR | 43% |
Practical Comparison: Which Is More Advantageous?
| Annual Gross Income | Capital Gain 33,500 EUR | 26% Substitute Tax | Standard IRPEF (estimate) | Best Choice |
|---|---|---|---|---|
| 15,000 EUR | 33,500 EUR | 8,710 EUR | ~8,600 EUR | Similar, slight advantage with IRPEF |
| 30,000 EUR | 33,500 EUR | 8,710 EUR | ~11,000 EUR | 26% Substitute Tax |
| 50,000 EUR | 33,500 EUR | 8,710 EUR | ~14,400 EUR | 26% Substitute Tax |
In general, the 26% substitute tax is advantageous when the taxpayer's overall income exceeds 28,000 EUR per year.
Special Cases: Gifts, Inheritances, and Primary Residence
Properties Received as Gifts
If the property was received as a gift, for the purposes of calculating the 5-year period, the reference date is the donor's original purchase date (not the date of the gift). This means that if the donor had purchased the property more than 5 years before the gift, the capital gain is not taxable even if the recipient sells immediately after receiving the property.
For calculating the capital gain, the reference cost is that incurred by the donor, increased by any taxes paid on the gift.
Inherited Properties
Capital gains from the sale of properties acquired through inheritance are never taxable, regardless of the time elapsed between the inheritance and the sale. This is one of the most important exemptions provided by the TUIR.
Primary Residence Tax Benefits
If the property was purchased with primary residence tax benefits and is sold within 5 years, the tax benefits are forfeited (difference between the reduced tax and the full tax) unless a new property is purchased within one year of the sale. However, if the property was used as a primary residence for the majority of the period, the capital gain remains exempt.
Capital Gains on Properties Renovated with the 110% Superbonus
From 2024, the legislation introduced specific rules for properties that benefited from the 110% Superbonus. If the property is sold within 10 years of the completion of the subsidized works, the capital gain is taxable and the costs of works eligible for the 110% deduction cannot be included among acquisition costs for the purpose of calculating the capital gain, if the seller opted for the invoice discount or credit transfer.
This rule does not apply if the property was used as a primary residence for the majority of the ownership period.
How to Declare the Capital Gain
The capital gain must be declared in the Redditi PF tax return (or in the 730 form if opting for standard taxation), in section RL (Miscellaneous Income), line RL6. If the 26% substitute tax is chosen, the payment is made by the notary at the time of the sale and it does not need to be included in the tax return.
Legal Strategies to Reduce the Capital Gain
- Wait for the 5 years: the simplest and safest strategy to eliminate taxation entirely
- Use the property as primary residence: if possible, transfer your residence there and live in it for the majority of the ownership period
- Document all costs: keep renovation invoices, notary receipts, brokerage receipts to maximize deductible costs
- Evaluate the most advantageous tax regime: always compare the 26% substitute tax with standard IRPEF taxation
Capital Gains on Building Land
Unlike buildings, capital gains on building land are always taxable, regardless of the ownership period. Neither the 5-year exemption nor the primary residence exemption applies. The calculation follows the same logic: difference between the sale price and the purchase cost (including documented improvement costs). For land as well, it is possible to opt for the 26% substitute tax as an alternative to standard IRPEF taxation. It is important to verify the urban planning classification of the land at the time of sale, since the "buildable" qualification depends on the current municipal urban planning instrument, not the cadastral designation.
Frequently Asked Questions (FAQ)
After how many years is no capital gains tax payable?
After 5 years from the date of purchase (date of the notarial deed), the capital gain on the sale of buildings is no longer taxable. For building land, however, taxation always applies, regardless of the ownership period.
Is capital gains tax payable on a primary residence?
No, if the property was used as the primary residence of the seller or their family members for the majority of the ownership period, the capital gain is exempt from taxation even if the sale occurs within 5 years.
How is the capital gain calculated on an inherited property?
Capital gains on inherited properties (acquired through succession) are never taxable. This exemption applies regardless of the time elapsed and the amount of the gain.
Can renovation costs be deducted from the capital gain?
Yes, provided that the works are documented with proper invoices, that they were actually paid (preferably by bank transfer), and that they increased the property's value. Ordinary maintenance expenses are not deductible.
Is the 26% substitute tax always advantageous?
No, it is only advantageous if the taxpayer's overall income is high enough to push the capital gain into IRPEF brackets above 26%. For low incomes (below 28,000 EUR total including the capital gain), standard IRPEF taxation may be more advantageous.
Is capital gains tax payable even if selling to a family member?
Yes, selling to a family member is a sale for consideration like any other, and the capital gain is taxable according to standard rules. Note: if the sale price is significantly below market value, the Revenue Agency may adjust the value for registration tax purposes.
How do capital gains work for gifted properties?
For properties received as gifts, the 5-year period is calculated from the original purchase date of the donor. The reference cost for calculating the capital gain is the cost incurred by the donor, plus any gift taxes and renovation costs incurred by the recipient.
