France taxes capital gains on securities (shares, dividends, interest) by default under the Prélèvement Forfaitaire Unique (PFU, or 'flat tax'): 30% total, comprising 12.8% income tax plus 17.2% social contributions. Taxpayers may elect instead for the progressive income tax scale if their marginal rate is lower. Crypto gains are taxed slightly higher, at 31.4% (12.8% + 18.6% social contributions) since a 2026 change. Real estate capital gains follow separate rules, with a combined effective rate of 36.2% on taxable gains, plus a surtax on gains exceeding €50,000.
