In 2025, taxes represent nearly a third of consumers' gas bills. This weight almost doubled between 2013 and 2025. Over the past two years, taxation on natural gas has been changing rapidly. Every item on the bill is affected, between a record increase in excise duties on gas and a single VAT rate.
Since the end of the tariff shield and the energy crisis, businesses and households have been under constant pressure on their energy budgets. How to anticipate, control and optimize your costs?
SirEnergies helps you understand fiscal mechanisms in a context of strategic change in the State.
Since 2022, the excise on natural gas has been the new name given to Domestic consumption tax on natural gas (TICGN). Over the past two years, its spectacular increase has weighed heavily on the energy bill of businesses and households.
Created in 1986, the TICGN initially aimed to encourage consumers to limit their use of natural gas and, therefore, to reduce CO emissions2 associates.
Since 2017, the TICGN has integrated two contributions:
Renamed excise on gas in 2022 to align with European law, this tax contributes to financing of energy policies, solidarity schemes and the development of biogas.
The 2025 finance law provides for a reduction in the excise duty on natural gas From the 1Er August 2025. Fixed at 15.43 euros/MWh, its amount remains however almost twice as high as that applied between 2018 and 2023.
After five years of fiscal stability, in 2025, the State affirmed its desire to regulate energy taxation.
Initially designed to increase gradually, the excise duty on natural gas has experienced a An unsteady evolution, against a background of economic and geopolitical turmoil.
In 2018, the tax has undergone a first jump of 43.7% with the integration of the carbon tax (climate-energy contribution — CIE). The excise on gas was then Frost until 2023 to protect consumers, under the effect of the Yellow Vests movement, the Covid-19 health crisis and the conflict in Ukraine.
Since 2024, the State has been engaged in a catch-up phase. In 2024, the amount of excise duty on natural gas almost doubled, with a 95% increase linked to the end of the tariff shield and galloping inflation.
2025 marks a slight relaxation with a price reduced from 17.16 euros/MWh to 15.43 euros/MWh. However, this amount represents a increase of 84% compared to 2023. This rate now includes:
An increase of 4.89 euros/MWh to ensure territorial equalisation and guarantee public service in non-interconnected areas, in Corsica and in overseas territories.

Value Added Tax (VAT) represents an important part of gas taxation. The 2025 finance law increases consumers' bills by homogenizing VAT rates to 20%.
VAT covers all elements of gas bill, from consumption to supply, including delivery costs and even taxes (gas excise and CTA)!
Until 2025, two VAT rates applied to natural gas:
With the 2025 finance law, the distinction between VAT rates disappears for electricity and gas.
From the 1Er August, one single VAT rate of 20% will be applied to all gas bill items, with an increasing impact on the energy budget of businesses and individuals.
This harmonization puts France in compliance with European law requirements, which imposes consistent VAT for the same service.
Since 2004, the Transport Tariff Contribution (CTA) has played a key role in financing the pension plan for the electricity and gas industries (IEG).
The CTA is calculated based on a Percentage applied to third party access rates to the transport network (ATRT) and to the distribution network (LATE) natural gas.
Its rates, set by the State, apply to the fixed portion excluding tax of transport costs, regardless of energy consumption. Since 2013, the rates have been as follows:
The CTA on natural gas is one of the few energy taxes that remains stable over the long term. Its rates remain unchanged since the 1Er January 2013.
With a limited impact on gas bills, CTA participates in thesocial balance in the energy sector. By supplementing the insufficient provisions accumulated by the State at the time when electricity and gas companies were nationalized, this tax ensures the sustainability of historic pension plans.
To conclude...
Over the past two years, tax decisions have redefined the rules of the game, with a sudden increase in the excise duty on natural gas and the homogenization of VAT. The objective is twofold for the State: to accelerate the energy transition by encouraging the reduction of fossil gas consumption, while at the same time replenishing public finances. However, this fiscal and environmental strategy raises a major social challenge, with the risk of worsening inequalities in access to energy for the most fragile businesses and households.
It is possible to stop being subject to taxes!
In a context of rising taxes, adopting a proactive energy strategy is no longer an option for businesses.

C'est le levier le plus rapide pour obtenir des résultats visibles. L'éclairage représente environ 40 % de la consommation d'électricité d'une commune.
Passer au LED avec pilotage intelligent permet de réduire la facture de 50 à 80 %, avec un retour sur investissement (ROI) rapide, souvent estimé à 2 ou 3 ans.

Même le bâtiment le plus moderne et le mieux isolé perd son efficacité si ses usages sont inadaptés. La technologie et les normes ne suffisent pas : la transition énergétique est avant tout une transformation humaine.
Derrière chaque kilowattheure consommé se cache une habitude.
Un collaborateur sensibilisé comprend qu'ouvrir une fenêtre alors que le chauffage est allumé ou laisser un ordinateur en veille consomme de l'énergie inutilement. En replaçant l'humain au centre de la stratégie de gestion de l'énergie, l'entreprise s'assure que ses équipements performants sont utilisés de manière optimale, garantissant ainsi une rentabilité durable et un impact environnemental réduit.

L'augmentation s'explique par la revalorisation de l'Accise sur le gaz à 16,39 €/MWh et la hausse de 3,41 % du tarif de transport (ATRT 8).
S'y ajoute l'entrée en vigueur des Certificats de Production de Biogaz (CPB), un nouveau coût réglementaire pour soutenir le biométhane.
Face à ces évolutions, Sirenergies vous accompagne dans l'achat de gaz naturel pour sécuriser vos prix malgré la volatilité du marché.
