Guidance based on the CGI protects under the CIBS too
The protection against changes of administrative position rests on article L. 80 A of the LPF. Its third paragraph is the one used most in practice: "Where the taxpayer has applied a tax provision in accordance with the interpretation that the administration had made known through its published instructions or circulars and had not withdrawn at the date of the transactions concerned, it may not pursue any reassessment by arguing for a different interpretation" (LPF, art. L. 80 A, our translation). Article L. 80 B extends the protection to formal positions on a given set of facts, that is, to individual rescrits, and article L. 64 B rules out the abuse-of-law procedures (articles L. 64 and L. 64 A) where the taxpayer consulted the central tax administration in writing before concluding the deed, supplying all relevant information, and received no reply within six months.
The difficulty was easy to state. Guidance comments on a text. When that text is repealed and rewritten elsewhere, under another number and sometimes in other words, a taxpayer could fear being told that the guidance relied on concerns a provision that no longer exists. The rescrit of 18 February 2026 already answered in the negative, asserting that the guidance remained binding under articles L. 80 A and L. 80 B on the basis of the rule of correspondence of references (art. 46, I, 1°). That was then the position of the tax authorities.
Since the ordonnance of 27 July 2026, the solution appears in the recodification ordonnance itself. Article 46, III of ordonnance n° 2025-1247 provides: "For the purposes of articles L. 64 B, L. 80 A and L. 80 B of the Tax Procedure Code, the administration's interpretation of the provisions of the General Tax Code relating to value added tax transferred to the Code of Taxes on Goods and Services by this ordonnance constitutes an interpretation of the provisions relating to value added tax appearing in that same code" (our translation). The publication of 7 October 2026 restates, in the rescrit itself, that the binding guidance is unchanged.
In practice, according to point 2.1 of the updated rescrit, the following are covered: all BOFiP commentary, answers to parliamentarians' written questions, and positions taken in individual rescrits, provided they have been neither withdrawn nor lapsed before 1 January 2027. A recent example is the guidance on VAT on the margin, which the Government confirmed on 1 October 2026 (our commentary on the ministerial answer): it continues to protect resellers after the switch, even though article 268 of the CGI becomes, in the numbering resulting from the ordonnance of 27 July 2026, articles L. 231-18 to L. 231-20 of the CIBS (the ministerial answer still cites the December 2025 numbering).
For transactions and disputes straddling 1 January 2027, the practical rule follows from the text of article L. 80 A: the binding guidance is the guidance not withdrawn at the date of the transactions concerned. A 2026 supply remains governed by the CGI and by the guidance then published; a 2027 supply falls under the CIBS, but the same guidance continues to protect it until withdrawn. In a claim or a brief, it is prudent to cite the CGI article commented on, the CIBS article that restates it, and article 46, III. The differences between the two versions that we have identified (leases conferring a right in rem, promises to sell) are set out in the section on the recodification that is not strictly substance-neutral of our reference page.
What the protection covers
The recodification itself: a change of number or wording does not allow the tax authorities to set aside guidance published under the CGI. It applies to the BOFiP, ministerial answers, individual rescrits (L. 80 B) and the prior-consultation procedure in abuse-of-law matters (L. 64 B).
What it does not cover
Guidance that the tax authorities later withdraw or amend. The BOFiP will be overhauled progressively along the plan of the CIBS: for transactions after a new publication, the new guidance will apply. Paragraph III also covers only provisions that were transferred: a genuinely new rule of the CIBS has no earlier guidance to rely on.
