New portal French diesel tax refund

Where traders submitted their applications through the customs portal for years SIDECAR Web has changed the procedure step by step since 2025. In the meantime, the French government has worked on a new online portal that is now live. This new environment makes the applications simpler and faster. Until the end of 2024, all refund applications were submitted through French Customs (DGDDI).

This new environment makes the applications easier and faster.

From 1 January 2025, responsibility was transferred to the French tax authorities (DGFiP). This means the refund process no longer runs through a separate customs procedure, but has become part of the tax authority system. The government also promises better integration with existing systems, enabling more transparent application status and payment processing.

The launch of this portal was initially planned for early 2025, but due to technical problems the launch was postponed. Since this summer, the essential errors in the system have been eliminated and the portal is now open for use. There is also good news for those entrepreneurs who have not yet applied for excise duty in France.

no permit or access procedure applies. There is still a retroactive period of 2 years. The remuneration of the French diesel tax is currently at € 0,1571 per litre. Should you need help with your French diesel tax returns, we at Delta may be of service to you.
