Exact Calculation of Real Estate Capital Gains: Methodology and Considered Elements
The real estate capital gain (CG) corresponds to the difference between the sale price of a property and its acquisition price, adjusted for certain fees and investments. For a French investor, the precise calculation of this CG is essential to anticipate the tax due.
General formula:
Gross capital gain = Sale price - Adjusted purchase price
Costs of renovation works carried out (under specific conditions)
Specifically:
Notary fees and registration duties: either their actual amount, or a flat rate of 7.5% of the purchase price (choice of the buyer). This flat-rate option is often used to simplify the declaration (source: Official Bulletin of Public Finances - BOFiP-Taxes).
Renovation costs: can be deducted if invoiced and carried out by professionals (excluding routine maintenance expenses). Since 2012, the owner can opt for a flat rate of 15% of the purchase price if no supporting documents are provided, provided the property has been held for more than 5 years.
Numerical example:
A property purchased for €200,000 in 2010, with actual notary fees of €15,000 and invoiced renovation works of €20,000 in 2015, sold in 2023 for €300,000.
This capital gain will be the taxable base before allowances for holding period.
Allowances for Holding Period: Income Tax (IR) Regime
The tax regime for real estate capital gains subject to income tax provides a system of progressive allowances based on the duration of ownership of the property.

Total exemption from income tax

Beyond 22 years of ownership, the capital gain is fully exempt from income tax. This is an important lever for investors wishing to optimize the taxation of their resale.
Allowances for Holding Period: Social Contributions (SC)
In addition to income tax, real estate capital gains are subject to social contributions at a global rate of 17.2% (CSG, CRDS, etc.). The allowance regime differs:

Total exemption from social contributions
Source: Article L. 136-6 et seq. of the Social Security Code, updated 2024.
Social contributions are only exempt after 30 years of ownership, i.e., 8 years longer than for income tax exemption. This differential is crucial for long-term tax planning.
Specific Exemption: Primary Residence
A fundamental point concerns the primary residence, which benefits from a total and permanent exemption from real estate capital gains tax, regardless of the amount or holding period. This measure aims to protect the main housing of French residents and is codified in Article 150 U, I-1° of the CGI.
Main conditions:
The property must be the primary residence at the time of sale.
It is possible to sell a property previously acquired or rented, but the sale must occur while the property is actually occupied as the primary residence.
There is tolerance for temporary situations (e.g., professional relocation) under certain conditions.
This exemption is a major asset protection lever, as it completely removes taxation on the capital gain, including social contributions.
Other Specific Exemptions and Allowances
Besides the cases of the primary residence and the holding period allowance, other partial or total exemptions may apply:
Small sale: sale of a property with a sale price below €15,000 (total exemption).
Exemption for elderly or disabled persons: exemption subject to income and age conditions (Article 150 U, III of the CGI).
Exemption for the first sale of a property other than the primary residence: subject to conditions related to the reinvestment of the sale proceeds for the acquisition of the primary residence.
These exemptions must be analyzed on a case-by-case basis and concern only a minority of transactions.
