Expert-Comptable & Crypto Clients in France: Scope, Limits, DAC8 Prep

This is the France-specific spoke of the crypto-practice series: how the rules of the expert-comptable profession, and recent French law, shape what a cabinet can and cannot do for a crypto client. A French expert-comptable can serve crypto clients, and many specialise in it, but the role has a defined scope and limits under the rules of the Ordre des experts-comptables, and DAC8, transposed via the loi de finances 2025 and in force from 2026, changed what client readiness means. Where building a crypto practice is jurisdiction-neutral, this guide is the role, the limits, and the prep in a French context. It is hedged, because it is governed by French professional and tax rules.

The short version

• A French expert-comptable can serve crypto clients; the role stays within its professional-rules scope (the Ordre des experts-comptables, independence, and the boundary between accounting and attestation work and legal or tax advice).
• Legal and tax advice generally belongs to other professions, such as an avocat fiscaliste; the expert-comptable does not absorb it by default.
• DAC8 was transposed via the loi de finances 2025, is in force from 1 January 2026, and the first automatic exchange is in 2027, which adds reconciliation and client-readiness work to the engagement.
• The Règlement ANC n° 2026-01 recast crypto accounting (mandatory for financial years beginning on or after 1 January 2027, early application possible); the engagement follows the recast text, with no assumed PCG numbers.
• Crypto clients often need an avocat fiscaliste alongside the cabinet for legal and tax positions outside the accounting scope.
• This is governed by French professional and tax rules; confirm with the Ordre and a French avocat fiscaliste. This is not professional, legal, or tax advice.

The role and its scope

A French expert-comptable can serve clients with crypto-assets, and specialist firms exist. The role operates within a defined scope and the professional rules of the Ordre des experts-comptables, including independence and the boundary between accounting and attestation work and the legal or tax advice that belongs to other professions. Serving crypto clients applies those rules to a more complex asset; it does not change them. The exact scope is governed by French professional rules rather than assumed.

What is outside scope

The expert-comptable's mission is accounting and related attestation. Legal advice and certain tax-representation acts are generally the domain of other regulated professions, such as an avocat. The boundary matters more with crypto, because clients often need legal and tax positions, not just books. This guide does not define the exact frontier; it is set by French professional regulation and confirmed with the Ordre and counsel. The practical point is that the expert-comptable does not absorb the client's legal or tax advice need by default (see declaring crypto with an accountant in France).

What DAC8 changed

DAC8 was transposed into French law via the loi de finances 2025 and has been in force from 1 January 2026, with the first automatic exchange of crypto-asset data to tax authorities in 2027. For the expert-comptable, client books increasingly have to be reconciled against CASP-reported data, and clients made ready before the exchange (see DAC8 client readiness and the reconciliation workflow). The precise obligations sit with the client and the firm under tax and professional rules and should be confirmed with an avocat fiscaliste. The exact transposing article is not asserted here; confirm it against the current legislative text.

The ANC 2026-01 recast

The Règlement ANC n° 2026-01 du 9 janvier 2026 recast the French PCG "crypto-actifs et assimilés" section, mandatory for financial years opening on or after 1 January 2027, with early application possible. A French crypto engagement follows the recast text rather than an ad hoc approach, and the specific account treatment is read from the current ANC text with the expert-comptable (see ANC 2026-01 crypto accounting). This guide asserts no PCG account numbers.

Pair with an avocat fiscaliste

Crypto clients frequently need legal and tax-advice positions (residence, instrument characterisation, sanctions, structuring) that sit outside the accounting scope, so a French avocat fiscaliste commonly works alongside the expert-comptable. Clarify who owns which question at engagement time so the client does not assume the expert-comptable covers everything. The division of roles is governed by professional rules and should be confirmed rather than assumed.

Practical guidance

1. Serve crypto clients within the Ordre's scope, respecting independence and the accounting and attestation boundary.
2. Do not absorb legal or tax advice by default; it is another profession's domain.
3. Add DAC8 reconciliation and client readiness (loi de finances 2025; in force 2026; exchange 2027).
4. Follow the Règlement ANC 2026-01 (financial years from 2027) and read accounts from the current text.
5. Pair with an avocat fiscaliste and clarify the role division at engagement time.
6. Confirm scope and obligations with the Ordre and a French avocat fiscaliste. This is not professional, legal, or tax advice.

How vendor tools support the engagement

Cryptio and Bitwave provide the French-configurable crypto sub-ledger and reconciliation an expert-comptable can operate. Confirm the French chart of accounts is configured to the current Règlement ANC 2026-01 treatment. The tool supports the engagement; the scope, the ANC application, and the professional responsibility remain the expert-comptable's.

Where Wag3s fits

Wag3s for accountants gives a French cabinet a crypto sub-ledger with a configurable ANC-aligned chart of accounts, FEC export, reconciliation, and a DAC8 reconciliation surface. It is the cabinet's tooling layer, not its professional judgement: the expert-comptable's scope, the ANC application, the DAC8 obligations, and the legal and tax boundary stay professional-rules- and counsel-confirmed.
