2 In 2026, when you pay any remaining income tax owing on your 2025 investment
income: The balance remaining will depend on the tax method that you choose.
Capital losses can be offset against capital gains, see Factsheet No.9. The payment of tax on capital gains and losses on the sale of securities received in 2024 will be due to the tax authorities in September 2025.
To help you choose between the tax methods available to you, before you complete your 2024 tax return, we recommend using the tax authorities’ simulator available on the impots.gouv.fr website and choosing between the 2 options proposed in step 1 below:
Step 1
Option A, I opt for: the flat tax (PFU) of 30%
Option B, I opt for: the progressive scale
Step 2
The amount of my dividend, which is pre-completed by the tax authorities, is shown in Box 2BH of Form 2042 (Revenus déjà soumis aux prélèvements sociaux avec CSG déductible si option barème) and any advance withholding tax payment deducted when the dividend was paid is shown in Box 2CK (Prélèvement forfaitaire non libératoire déjà versé en 2024 voir Fiche Pratique n°4).
Step 3
If I made capital gains from sales in 2024, I must enter the amount of these gains in Box 3VG of Form 2042C (Capital gains before allowances), without taking into account allowances.
Step 4
Only for Option B
I enter any allowances for the holding period in Box 3SG of Form 2042C (Abattement pour durée de détention de droit commun).
Please note: the forms and boxes listed in the table above will be announced by the tax authorities in April 2025, after the publication of the 2025 Shareholder Factsheets.
