France’s tax landscape for multinational enterprises and cross-border private clients has evolved rapidly since the global minimum tax (Pillar Two) began to bite and the EU introduced DAC8/CARF reporting for crypto-assets. This guide summarises practical obligations, key deadlines and defensive strategies relevant to groups and wealthy non-residents operating with a French nexus as of 26 October 2026.

It focuses on three intersecting risk areas: (i) the operational mechanics of Pillar Two compliance in France (forms, filing routes and top‑up tax mechanics); (ii) the new transparency and reporting obligations for crypto service providers under DAC8/CARF and their implications for taxpayers; and (iii) cross‑border defensive tools, documentation, treaty procedures and litigation planning, that preserve rights and mitigate exposures in audits.

Pillar Two essentials for France

France has transposed the GloBE/Pillar Two framework into domestic law and published operational filing routes for groups in scope, including notification, the GloBE Information Return (GIR) and a liquidation/top‑up tax return. French forms referenced by the tax administration include the notification (form n°2065‑INT‑SD), the GIR (form n°2259‑SD) and the liquidation/notice of payment (form n°2272‑SD).

The OECD model (GloBE) remains the policy basis and France follows the Inclusive Framework approach (IIR, UTPR and the QDMTT options). Practically, groups with consolidated revenues above the EUR 750 million threshold must assess local filing obligations and determine whether centralised filing (a single jurisdiction filing the GIR) is available and appropriate.

Deadlines and calendars have been published by the French tax authority: notification and GIR filing windows and the timing for payment of any domestic top‑up tax are defined in the tax code and in administrative guidance; the tax administration has also issued specific technical guidance to support electronic filing and payment. Compliance workflows should therefore be driven by the French schedule for the relevant fiscal year and the group’s chosen filing strategy.

Operational compliance and filing roadmap

First, identify the filing constituent entities and decide whether France will be the filing jurisdiction or whether the group will centralise filing in another implementing jurisdiction. The French notification (2065‑INT‑SD) sets the filing entity and enables access to the online GIR and payment channels.

Second, prepare the GIR (GloBE Information Return) data set in accordance with the OECD GIR XML schema and validation rules. The GIR system expects machine‑readable XML submissions (OECD schema) and many administrations, including France, expect validated XML that follows OECD guidance and the GIR MCAA exchange arrangements. Test your XML generation early and treat reconciliation to statutory accounts and tax returns as a mandatory control.

Third, plan top‑up tax payment mechanics and inter‑entity liability. If a domestic top‑up tax (DMTT) or under‑taxed profits rule (UTPR) exposure arises in France, the group must file the liquidation statement (form 2272‑SD) and follow French payment procedures; the French administration has published the relevant filing forms and practical notes for the first filing cycles.

Crypto specific obligations: DAC8, CARF and French transposition

The EU’s DAC8 (implementing the OECD CARF) and France’s transposition (Finance Act 2025 and Decrees No. 2025‑1276/1277) impose broad reporting duties on crypto‑asset service providers (PSCA), including exchanges, custodians and certain wallets and broker services. These rules came into force on 1 January 2026 with the first platform records to be collected from that date and first reporting to tax authorities scheduled thereafter.

French transposition identifies which providers are in scope (domestic PSCA and certain foreign providers with French nexus) and sets the timing and format for reporting to the DGFiP; national decrees and administrative instructions define data fields, due diligence and certification obligations for existing clients. Expect crypto reporting data to be exchanged automatically between EU tax authorities under DAC8/CARF.

For groups operating crypto businesses or holding material crypto positions, DAC8 dramatically increases the probability that tax administrations will receive transaction‑level intelligence about on‑chain activity, transfers to self‑custody, staking, lending and income‑like events, all of which can trigger reclassifications or inquiries. Treasury and compliance functions must therefore map platform data to tax positions and be prepared to explain valuation, timing and taxable events to the DGFiP.

Reconciling crypto with GloBE: valuation, timing and ETR issues

Pillar Two’s ETR computations and the treatment of ‘covered taxes’ depend on reliable financial accounting and tax reconciliations. Crypto positions raise valuation, timing and classification issues (crypto‑to‑crypto swaps, staking rewards, forks/airdrops, decentralized finance income) that can materially affect adjusted covered taxes and the numerator/denominator used in GloBE calculations. Robust reconciliations and consistent accounting policies are therefore essential.

Key operational points include consistent recognition dates for crypto income (market value at receipt or disposal), careful treatment of crypto taxes withheld or payable in other jurisdictions, and clear documentation of any carve‑outs (e.g., substance‑based carve‑out) relied on in GloBE computations. Groups should coordinate tax and treasury teams to capture taxable events and withholding correctly across jurisdictions.

Because DAC8/CARF will feed tax administrations with granular transaction data, gaps between reported platform data and group filings are likely triggers for enquiries. Anticipate data reconciliation requests and prepare standardized explanations: proof of trade flow, counterparty identity, ledger extracts, wallet‑to‑wallet transfer narratives and the accounting policy supporting recognition and valuation choices.

Cross‑border defenses: documentation, treaty remedies and MAP

Preparation is a defensive imperative. Maintain contemporaneous transfer pricing documentation, GIR workpapers, ETR support schedules, and crypto transaction ledgers that tie to audited financials. Administrative documentation reduces the risk of adjustment and fortifies positions in any competent‑authority engagement or litigation.

When disputes arise, treaty remedies (MAP) and the updated OECD Manual on Effective Mutual Agreement Procedures (MEMAP, 2026 edition) are core tools for cross‑border resolution. The MEMAP (2026) provides practical guidance and best practices for competent authority engagement and can inform protective steps, such as filing a timely MAP request and preserving arguments to avoid double taxation while MAP is pending.

Advance Pricing Agreements (APAs), unilateral or bilateral, and proactive pre‑filing with competent authorities (including protective disclosures where necessary) can materially reduce transfer pricing risk and the chance of costly Pillar Two disputes. Where available, arbitration clauses in treaties or EU dispute‑resolution directives should be considered as part of a structured dispute‑resolution plan.

Practical takeaways: audit readiness, liquidity planning and litigation posture

Liquidity planning: Pillar Two top‑up tax and potential adjustments from tax administrations require cash planning. Model scenarios for IIR, UTPR and DMTT exposures and build payment timing and funding options (inter‑company loans, local cash retention, payment allocations) into treasury forecasts. France’s payment channels and the 2272‑SD process should be integrated into that planning.

Audit readiness: for crypto positions, preserve chain‑level evidence, exchange statements, KYC/auto‑certification records and attestations prepared by PSCA. For Pillar Two, preserve GIR inputs, reconciliations, and the legal analysis underpinning positions taken on tax credits, paid taxes and carve‑outs. A clear audit file reduces both settlement risk and penalty exposure.

Litigation posture: involve counsel early. Where MAP is a realistic route, prepare a concise competent‑authority brief that explains the legal and factual basis for adjustments, preserve rights under domestic appeal procedures and monitor relevant case law (administrative and judicial decisions in France and EU precedents) that may affect argumentation on residence, characterization or retroactivity.

Conclusion: The convergence of Pillar Two, DAC8/CARF and enhanced GIR technical requirements means that French tax risk for groups and crypto‑facing taxpayers is both higher and more solvable with early, documented action. Compliance is now a combined exercise in tax technical work, IT/engineered reporting and classical treaty‑ and audit‑defence planning.

Key next steps for in‑scope groups and high‑net‑worth individuals: (1) map exposure and decide on centralised vs local GIR filing; (2) reconcile crypto and accounting systems to GIR and DAC8 reporting outputs; (3) secure documentation to support GloBE positions and be ready to engage competent authorities or invoke MAP if cross‑border disputes arise. Early, specialist advice and a coordinated tax‑tech playbook are essential.
