France VAT-CIBS Reform: Complete Guide for Businesses (September 1, 2026)
On September 1, 2026, all French VAT rules transfer from the General Tax Code (Code général des impôts, CGI) to the new Code des impositions sur les biens et services (CIBS). This reform is described as legally neutral (à droit constant) — no changes to VAT rates, deduction rules, or exemptions — but carries concrete practical implications for every company operating in France.
US parallel: Think of this as a scenario where Congress reorganises the Internal Revenue Code — renumbering sections and modernising language without changing the underlying rules. All documentation, software, and legal references citing the old section numbers require updating, but the tax owed does not change.
What Is the CIBS and Why Does It Matter?
The Code des impositions sur les biens et services was created by ordinance in December 2021 and initially covered specific product taxes (tobacco, alcohol, electricity). It is now being expanded into a single, thematically organised code for all French indirect taxes on goods and services — replacing the patchwork of TVA articles spread across the CGI since the 1960s.
Scale of the reorganisation:
- ~230 CGI articles on TVA → replaced by ~1,000 CIBS articles in four thematic blocks
- New architecture: General Regime | Cross-sector Special Regimes | Intra-EU and International Transactions | Sector rules (agriculture, real estate, transport, digital, healthcare…)
- Terminology update: "intracommunautaire" → "intra-européen" throughout; terms realigned to current CJEU case law
What Changes vs. What Stays the Same
What does NOT change on September 1, 2026
| Element | Status after September 1, 2026 |
|---|---|
| Standard VAT rate (20 %) | Unchanged |
| Reduced rates (10 %, 5.5 %, 2.1 %) | Unchanged |
| VAT franchise en base threshold | Unchanged |
| CA3 / CA12 / OSS filing regimes | Unchanged |
| Deduction rules and pro-rata calculation | Unchanged |
| E-invoicing mandate timeline | Unchanged (reception Sept 2026; SME emission Sept 2027) |
| Reverse-charge / auto-liquidation rules | Unchanged |
What changes operationally
- Article numbering: legal references shift from CGI articles (e.g., Art. 256, 271, 283 CGI) to new CIBS article numbers. Legal documentation, internal tax notes, and compliance procedures require updating.
- Terminology: several French tax law terms updated to match current EU VAT Directive language. Affects contract drafting and internal compliance policies.
- ERP and software: any system auto-generating legal article references on invoices or VAT reports may need a configuration update.
- Audit readiness: audits covering periods both before and after September 1, 2026 require navigating both CGI and CIBS references simultaneously.
Transition Period: CGI References Valid Until December 31, 2027
The ordinance provides a 16-month transition window:
- References to old CGI VAT articles remain legally valid and enforceable until December 31, 2027
- Invoices issued before September 1, 2026 citing CGI articles do not need to be reissued
- BOFiP (official French tax doctrine) will be progressively updated; existing guidance remains valid until superseded
- CGI/CIBS correspondence tables will be published by the DGFiP to facilitate the transition
5 Practical Steps for Your Business
1. Inventory documents referencing VAT articles Identify internal tax manuals, process notes, standard contracts, invoice templates, and ERP configurations that cite specific CGI VAT articles.
2. Brief your finance and legal teams Ensure accounting, finance, and legal teams understand the CIBS framework before September 2026. For audits spanning the date boundary, both reference systems must be understood.
3. Contact your software vendors Check your ERP, invoicing, and accounting software vendors about their CIBS update roadmap. Any system generating article references on VAT documents should be updated in time.
4. Use the transition as a VAT health check The CIBS reform is a natural moment to review your VAT risk profile: are all applicable rates correct? Are intra-EU supplies properly documented? Catching issues before an audit is always cheaper than correcting them during one.
5. Foreign companies registered for French VAT If your foreign company has a French VAT registration, your fiscal representative must be aware of the article renumbering. Substantive obligations are unchanged, but compliance documentation referencing specific articles should be updated.
For Foreign Companies and International Groups
For foreign multinationals or US/international investors with French VAT obligations, the practical takeaway is:
- Your French VAT rate, deduction rights, and intra-EU zero-rating rules are unchanged
- Your CA3 quarterly filing cadence is unchanged
- Your VAT registration number is unchanged
- What changes: the legal citation numbering in formal correspondence with the French tax authority
Frequently asked questions
Does the CIBS reform require changes to my French VAT registration?+
No. Your VAT number, filing obligations, cadence, and procedures are all unchanged.
Will the CIBS eliminate any current VAT exemptions?+
No. The reform is explicitly à droit constant — all existing exemptions, reduced rates, and deduction rules are preserved.
Our company uses a fiscal representative in France — what should they do?+
Your fiscal representative should already be tracking the DGFiP's CGI/CIBS correspondence tables. Confirm they will update your VAT compliance documentation and formal correspondence in time for the September 2026 transition.
We are currently under a French VAT audit — does the CIBS affect it?+
Periods before September 1, 2026 use CGI references. Periods after use CIBS references. If the audit spans both, both systems apply simultaneously. Your tax adviser should manage this transition seamlessly.
