Introduction
Selling a property is a key step in a homeowner's life. In Courbevoie, as elsewhere, calculating capital gains on real estate often raises questions and concerns, particularly regarding taxation and administrative procedures. At GUY HOQUET COURBEVOIE, we understand how essential it is to be well supported to understand each step, secure your transaction, and optimize the value of your assets. In this article, we guide you step by step to master the calculation of your capital gains, anticipate real estate taxes, and benefit from personalized support.
What is capital gains on real estate?
Capital gains on real estate corresponds to the difference between the sale price of a property and its acquisition price, once certain expenses and costs are deducted. It forms the basis on which any taxes payable upon sale are calculated. Understanding this mechanism is essential for any homeowner wishing to sell with peace of mind. Legislation evolves regularly, which is why it is wise to stay informed about the latest applicable rules in 2026 through trusted partners like GUY HOQUET COURBEVOIE.
Capital gains concern all real estate properties, except for the primary residence, which benefits from a total exemption. For secondary residences, rental investments, or professional properties, the calculation and taxation differ.
Calculating capital gains on real estate: key steps
Calculating capital gains on real estate is done in several simple steps, but support from a local expert remains a real asset to avoid errors. Here is the methodology to follow:
- Sale price: this is the amount actually received by the seller, including agency fees if they are the responsibility of the buyer.
- Acquisition price: this corresponds to the initial price paid at the time of purchase, to which certain costs (notary fees, registration fees, works under conditions) are added.
- Authorized deductions: certain works and costs (acquisition fees, construction, expansion, or improvement expenses, under conditions) can be added to the acquisition price. Notably, there is a flat rate for works if you have owned the property for more than 5 years.
- Final calculation: the gross capital gains correspond to the difference between the sale price and the acquisition price (adjusted for costs and works). The net capital gains are those subject to taxation after applying deductions for the duration of ownership.
To go further in simulating your capital gains, you can consult the tools offered by the public service or request a GUY HOQUET COURBEVOIE advisor for a personalized analysis.
Taxation: what taxation on capital gains on real estate in 2026?
In 2026, taxation on capital gains on real estate remains a major concern for sellers. Except in cases of exemption (primary residence, ownership duration over 30 years, certain specific sales), capital gains are subject to two types of taxes:
- Income tax: flat rate of 19%.
- Social contributions: overall rate of 17.2%.
Deductions for duration of ownership apply: you benefit from a total exemption after 22 years of ownership for income tax and 30 years for social contributions. At each step, it is important to anticipate the tax consequences with the support of a local agency like ours. For more details, consult the official page on taxes on capital gains on real estate.
Certain particular situations (selling a secondary residence to buy a primary residence, expropriation, first sales of land) entitle you to specific exemption regimes. Do not hesitate to seek advice from our teams to optimize your situation.
