Fuel prices: here’s why VAT is not decreasing

At the beginning of April 2026, French motorists are facing an uncomfortable situation with soaring fuel prices.

Due to geopolitical tensions in the Middle East and the partial blockage of the Strait of Hormuz, the price of diesel has surged by 52 cents in just five weeks, averaging €2.25 per liter. In response to this increase, pressure is mounting on the government to reduce VAT. However, the executive has firmly rejected such requests.

An Unaffordable Budgetary Gulf

The main reason is primarily arithmetic. In a context of closely monitored public deficits, the state cannot afford to lose revenue from fuel, the fourth-largest source of tax income in the country. A reduction of only 15 cents per liter would represent a cost of about 1 billion euros per month for public finances. With an already tight budgetary trajectory for 2026, Bercy refuses any notion of “whatever it costs” for global energy relief.

The VAT Mechanism: The Illusion of “Surplus”

While rising prices mechanically generate a VAT surplus for the state (estimated at 120 million euros for the month of March alone), the government emphasizes that this gain is largely offset by a decrease in overall consumption. The more expensive fuel is, the less French people drive, which reduces the taxable base. Furthermore, lowering VAT on a petroleum product is deemed “anti-ecological” by the Ministry of Ecological Transition, which prefers to redirect these funds towards social leasing or electric vehicle subsidies.

A Strategy of Targeted Measures

Instead of a general tax cut that would also benefit wealthier households, the government favors targeted assistance for the most vulnerable sectors (transporters, farmers, fishermen). For the general public, the state relies on the pricing strategies of distributors, such as price caps maintained by certain oil groups, while hoping for a return to calm in international markets to ease fuel prices.
