Definition and issues of capital gains
Capital gains represent the positive difference between the sale price of a property and its purchase price. For the seller, it constitutes a major asset and fiscal issue: anticipating capital gains well allows for optimizing the proceeds from the sale and securing all procedures. In a sector as sought after and dynamic as the 9th arrondissement, it is common to observe significant gaps between the initial purchase price and the resale price, amplifying the importance of accurately calculating capital gains. Our advisors find that, even for informed clients, the constant evolution of tax rules and the complexity of the local market regularly raise questions about the taxation applicable to each seller profile.
How is capital gains calculated?
The calculation of capital gains takes into account several elements. The sale price is reduced by the acquisition price, increased by purchase fees (notary, registration fees) and any works carried out (under conditions). In 2026, the modalities remain governed by the General Tax Code, with deductions applicable based on the holding period. For a seller in Paris 9, taking into account technical diagnostics, the Carrez law measurement — fully covered by our agency — and the precise valuation of improvements made to the property are key factors for maximizing the deductible amount during the calculation of capital gains. For example, clients who entrusted the sale of their apartment to Guy Hoquet Paris 9 Saint Georges benefit from personalized support for each step of this calculation, ensuring reliability and peace of mind.
Taxation 2026: what taxes on capital gains?
