The VAT reform in France planned for 2026 marks a structural evolution of tax law. From September 1, 2026, the VAT rules currently codified in the General Tax Code (CGI) will be transferred to a new framework: the Code of Taxes on Goods and Services (CIBS).
This reform, known as a “law-neutral” reform, aims to modernize and simplify the understanding of tax rules without changing their content. Its objective is to make VAT more transparent, consistent, and accessible for businesses and practitioners.
VAT and CIBS: a reform with no change in the law but with a strong operational impact
Even though the CIBS 2026 VAT reform does not fundamentally change the tax rules, it brings about significant changes:
Here’s what remains unchanged: the principles of VAT, the rules of taxation, and the mechanisms for deduction. However, it incorporates recent case law, particularly that of the CJEU.
And what’s changing: The structure of tax texts, the numbering of articles, the overall organization of VAT law
In practice, this involves a complete overhaul of the legal framework, with concrete impacts for businesses.
Transitional provisions: securing the transition to VAT under the CIBS system
To support the recodification of VAT in the Code of Taxes on Goods and Services (CIBS), transitional measures are planned to ensure legal continuity.
Administrative doctrine remains in effect subject to clarification from the tax authorities
The tax doctrine published in the BOFiP (Official Bulletin of Public Finances) and the rulings based on the French General Tax Code (CGI) are intended to remain useful references during the transition period. However, the conditions for their enforceability after the entry into force of the CIBS (Integrated Tax System for Business Continuity) still need to be clarified by the tax authorities.
Managing Time Periods (Before/After Reform)
Transactions carried out before the entry into force of the CIBS remain governed by the provisions of the French General Tax Code (CGI).
However, transactions carried out from September 1, 2026, onwards fall under the CIBS, which implies a temporary coexistence of the two frameworks in audits and disputes.
Scope of tax rulings
Rulings obtained under the French General Tax Code (CGI) remain valid for the situations they cover. However, their application must be assessed in light of the new CIBS guidelines, bearing in mind that the exact procedures for their enforceability after the reform comes into effect still need to be clarified by the tax authorities.
Administrative support tools
The administration will provide CGI/CIBS cross-reference tables to facilitate the identification of equivalencies between old and new articles, thereby facilitating the adoption of the 2026 VAT reform.
Temporary maintenance of regulatory texts
The current regulatory provisions remain applicable after the reform and will be gradually integrated into the CIBS. This avoids any disruption in the application of VAT rules.
CIBS VAT reform timetable for 2026 in France
Here are the main steps to remember:
- February – April 2026: Public consultation: As part of the 2026 VAT reform in France, the tax authorities have launched a public consultation on the transitional provisions related to the switch to the CIBS (Complementary and Interoperable Shared Accounting System). This consultation period runs from February 18 to April 15, 2026, to gather feedback from businesses and experts. This means that businesses can already rely on these provisions to ensure their VAT compliance practices are sound.
- September 1, 2026: Entry into force of the CIBS for VAT
- 2027: Finalization and ratification
This phased approach allows companies to anticipate changes.
Impact of the 2026 VAT reform on businesses
The reform of CIBS and VAT in France will have concrete consequences.
