The discount applies within the limit of one vehicle per hearth.
Thus, you must not detain, on the date of 1re registration of the new vehicle, other vehicles having benefited from the reimbursement scheme for large families.
Example :
You benefit from a reduction of CO2 malus and mass malus November 17, 2022 for a vehicle registered on 18 August 2022.
You are selling this vehicle on February 6, 2023.
You buy a new vehicle, registered for the first time on November 5, 2023.
You can ask in 2025 the reduction of CO2 malus and malus mass for this vehicle registered in 2023.
The reduction of CO2 malus is 20 g/km per child or 1 chch : Horses per child.
The reduction of malus mass is 200 kg per child.
Example :
If your vehicle's CO2 emission rate is 186 g/km, you benefit from a reduction of malus CO2 of 20 g/km per child, i.e. for 3 children, 60 g/km (3 x 20).
The CO2 emission rate thus reduced is at 126 g/km (186 - 60) to which corresponds a malus of €330 (tariff in force between 1 March 2025 and 31 December 2025 applicable on 1re registration in France).
Considering that the tariff in force between March 1, 2025 and December 31, 2025 applicable to a vehicle emitting 186 g CO2/km is fixed at €48,901, the reduction of the malus allows you to get a refund of €48 571 (€48 901 - €330).
Example :
If the mass in running order of your vehicle is 1,865 kg, you receive a mass malus reduction of 200 kg per child, i.e. for 3 children, 600 kg (200 x 3).
The mass in running order thus reduced is to 1,265 kg (1 865 - 600) to which corresponds a malus mass of €0 (tariff in force in 2024 and 2025 applicable at 1era registration in France).
Considering that the tariff in force in 2024 and 2025 applicable to a passenger vehicle 1,865 kg is fixed at €2,975, the reduction of the malus masse allows you to obtain a refund of the total amount of the malus masse initially paid, namely €2,975.
The CO2 malus and the mass malus are to be paid at the time of registration of the vehicle.
Then you need to claim refund.
The application file shall include the following documents:
- Completed and signed application form for reimbursement of CO2 malus and mass malus taxes. See the package leaflet
- Carte grise Copy of the Certificate of Registration (C of R) of the vehicle issued in the name of the applicant
