Real Estate Capital Gains: What They Are and How to Calculate Them

Real estate capital gains are the profit realized from selling a property at a price higher than the purchase price. Under Italian tax law, this positive difference may be subject to taxation, but there are important exemptions and options that are essential to know before selling a property.

When You Pay Capital Gains Tax

Real estate capital gains are taxable in the following cases:

  • Sale of a property purchased or built less than 5 years ago
  • Sale of buildable land, regardless of the holding period
  • Properties received as a gift, if the donor owned them for less than 5 years

When You Do NOT Pay

Capital gains are not taxable if one of these conditions applies:

  • The property was owned for more than 5 years
  • The property served as the primary residence of the seller or their family for the majority of the ownership period
  • The property was received through inheritance

How to Calculate Capital Gains

The formula for determining taxable capital gains is:

Capital Gains = Sale Price – (Purchase Price + Deductible Costs)

Costs Deductible from Capital Gains

Several documented expense items can be subtracted from the calculation:

Cost Item Deductible? Notes
Registration tax on purchase Yes Or VAT if purchased from a builder
Notary fees (purchase) Yes Purchase deed and mortgage
Agency commission (purchase) Yes With invoice or receipt
Renovations and improvements Yes Only documented work with invoice
Urbanization fees Yes If incurred for building works
Routine maintenance No Does not increase property value
Mortgage interest No Not considered a related cost

Taxation: Substitute Tax or IRPEF

The seller can choose between two taxation regimes:

Option 1 – 26% Substitute Tax

A flat rate of 26% is paid on the capital gains, directly to the notary at the time of the deed. This is the simplest choice and often the most advantageous for medium-to-high incomes.

Option 2 – Ordinary IRPEF Taxation

The capital gains are added to other income in the tax return and taxed according to the 2026 IRPEF brackets:

Income Bracket IRPEF Rate
Up to €28,000 23%
From €28,001 to €50,000 35%
Over €50,000 43%

Choosing IRPEF is only advantageous if the total income (including capital gains) stays within the 23% bracket, i.e., below €28,000.

Practical Example

Mario purchased an apartment 3 years ago for €180,000, paying €8,000 in notary fees and taxes, €5,000 in agency commission, and €25,000 in documented renovation. Today he sells for €270,000.

  • Deductible costs: 8,000 + 5,000 + 25,000 = €38,000
  • Taxable capital gains: 270,000 – (180,000 + 38,000) = €52,000
  • Substitute tax (26%): 52,000 × 0.26 = €13,520

If Mario had waited another 2 years (exceeding 5 years of ownership), he would not have paid any tax on the capital gains.

How to Use the Calculator

Enter the purchase price, the sale price, the deductible costs incurred, and the ownership period. The calculator will determine the taxable capital gains and the tax due under both the 26% substitute rate and IRPEF taxation, allowing you to choose the most advantageous option.
