France is expanding its fuel aid program for "heavy users" to include the last three months of 2026, according to government sources. The 100-euro aid, initially provided between April and September, will now cover the period from October 1 to December 31. This expansion is expected to affect up to 5.5 million French people, compared to 3 million previously. The aid remains fixed at 100 euros and corresponds to an equivalent of 40 cents per liter for an average consumption. Eligibility criteria include income limits: a single person earning up to 2,035 euros of net salary, a couple with one child up to 4,070 euros, and a couple with two children up to 6,100 euros. Applicants must be fiscally domiciled in France and be at least 16 years old as of December 31, 2024. Additionally, individuals must use a personal vehicle for work-related travel, specifically for trips between their home and workplace, with distances exceeding 15 kilometers per trip, 30 kilometers round trip, or 8,000 kilometers per year in a professional context. The vehicle must be thermal or hybrid non-rechargeable and regularly insured. Electric or hydrogen vehicles, heavy trucks, and certain service or official vehicles are excluded. Those who already received the 100 euros for the April to September period will automatically receive the additional 100 euros by mid-October 2026. Those who did not previously qualify but now meet the expanded criteria will need to apply. A new simulator will be available online on impots.gouv.fr on October 12, with applications opening on October 22, 2026. Payments are expected within ten days of application validation.
