Crypto Taxation in France After DAC8: Reporting, Audits and Voluntary Disclosure

From 1 January 2026, DAC8 – Directive (EU) 2023/2226 – applies across the European Union, requiring crypto-asset service providers to collect and report client data to national tax authorities, with France's Direction générale des finances publiques (DGFiP) as the designated receiving body. French holders of crypto-assets now face a materially higher risk of cross-border detection, coordinated audit activity and, where past filings were incomplete, potential penalties that compound over time. Understanding how the French legal and administrative framework intersects with these new EU obligations is an essential first step for any individual or entity with crypto-asset exposure in France.

DAC8 and DAC9: The EU Architecture in Brief

Directive (EU) 2023/2226 (DAC8) aligns the EU's automatic exchange of information framework with the OECD Crypto-Asset Reporting Framework (CARF). It imposes standardised due-diligence and reporting obligations on crypto-asset service providers operating within the EU, regardless of where their clients are tax-resident. The first reporting period covers data generated from 1 January 2026 onwards, meaning crypto-asset service providers must already be implementing the necessary technical and compliance infrastructure.

Alongside DAC8, Directive (EU) 2025/872 (DAC9) introduces EU-level exchange of GloBE information returns under the Pillar Two framework, ensuring that large multinational groups operating in France are subject to coordinated minimum-tax monitoring. Although DAC9's direct impact falls primarily on groups with consolidated revenues above the relevant threshold, the administrative machinery it creates sits within the same DGFiP infrastructure that will process DAC8 crypto data. The Commission opened infringement procedures on 30 January 2026 against member states that had not yet transposed these directives; France's transposition status should be verified against the latest official publications, as national implementing measures may have been adopted or remain pending.

The French Regulatory Landscape: DGFiP, AMF and ACPR

France has long maintained a relatively structured approach to crypto-asset oversight. The Autorité des marchés financiers (AMF) and the Autorité de contrôle prudentiel et de résolution (ACPR) share supervisory responsibility over crypto-asset service providers under the Prestataires de services sur actifs numériques (PSAN) regime, now evolving in parallel with the MiCA framework. DAC8 sits on top of this architecture: it does not replace the AMF/ACPR prudential and market-conduct rules, but it significantly extends the DGFiP's information base.

In practical terms, this means that a crypto-asset service provider registered or operating in France will simultaneously face AMF/ACPR compliance obligations and DAC8 reporting requirements flowing through to the DGFiP. For investors and corporate clients, the relevant consequence is straightforward: information that was previously self-reported – or not reported at all – will increasingly be supplied to the DGFiP automatically, without any action by the taxpayer. The Cour de cassation has in recent years addressed disputes touching on the tax characterisation of digital assets, and the DGFiP's audit capacity in this area has grown accordingly. Assuming that historical under-reporting will pass unnoticed is a posture that carries escalating risk.

Reporting Obligations Under French Law: What Has Changed

French resident taxpayers have for several years been required to declare foreign crypto-asset accounts on their annual income tax return, under obligations that predate DAC8. The significance of DAC8 is not that it creates an entirely new French domestic duty, but that it closes the enforcement gap by ensuring that data flows automatically from service providers to the DGFiP, making non-compliance far more detectable.

Key dimensions of the current French reporting picture include:

• Account declaration: French tax residents holding crypto-asset accounts with foreign platforms are required to declare those accounts. Failure to do so can trigger penalties and, in egregious cases, criminal referral.
• Capital gains reporting: Gains on the disposal of crypto-assets are subject to French tax. The applicable regime and rate depend on the taxpayer's status (individual, professional or corporate) and the nature of the activity. The rate applicable in any given situation is determined by French domestic law and, where relevant, applicable tax treaties; no specific rate is assumed here.
• DAC8 automatic exchange: From the 2026 reporting period, service providers must file standardised returns with the DGFiP. Cross-border exchange then enables other EU tax authorities to receive data on their residents' activity through French-registered platforms, and vice versa.
• Tax residency considerations: Individuals who have recently relocated – whether to or from France – should assess their tax residency status carefully. The DGFiP will receive data corresponding to accounts held during the reporting year, irrespective of when during that year the person was resident.

Audit Risk: How the DGFiP Is Likely to Use DAC8 Data

Tax administrations across the EU have been anticipating the DAC8 data flows for several years, and the DGFiP is no exception. The practical implication is that audit selection models will be recalibrated to incorporate crypto-asset information. Discrepancies between declared income or wealth and the activity visible in DAC8 returns are likely to trigger demandes de renseignements (requests for information) or formal vérifications de comptabilité and examens de situation fiscale personnelle (ESFP).

Several patterns of exposure stand out in the French context:

• Unreported foreign platforms: Taxpayers who held accounts with non-French platforms and did not declare them face simultaneous risk from DAC8 exchange and from France's existing foreign-account declaration rules.
• Mischaracterisation of activity: The boundary between occasional capital gains (flat-rate regime) and habitual trading (professional income, subject to a different regime) has been the subject of DGFiP guidance and litigation. Where the volume of DAC8-reported transactions substantially exceeds declared income, the DGFiP may reassess the applicable regime.
• Corporate and fund structures: Entities incorporated in France that hold crypto-assets on behalf of investors, or French branches of foreign funds, face their own reporting and tax obligations. DAC8 data will allow the DGFiP to cross-check entity-level filings against underlying transaction data.
• Inheritance and wealth transfers: Crypto-assets transmitted on death or by gift are in principle subject to French succession and gift taxes. Automatic exchange data may bring previously invisible assets into the DGFiP's view during estate or audit proceedings.

The enforcement timeline matters. Once the DGFiP opens a formal audit, the taxpayer's options narrow significantly. Statutory limitation periods, surcharge rates and the availability of penalty mitigation all differ depending on whether a disclosure is made proactively or after an audit has commenced. Acting before the DGFiP initiates contact is consistently the more favourable position.

Voluntary Disclosure: The French Framework and Its Limits

France does not currently operate a permanent, formalised voluntary disclosure programme equivalent to some other jurisdictions. However, the general principles of French tax procedure allow a taxpayer who spontaneously regularises a past filing to benefit from reduced penalties compared with those imposed following an audit-driven reassessment. The DGFiP has issued guidance over the years on regularisation for taxpayers with undisclosed foreign assets, and that framework – though not specifically designed for crypto-assets – remains relevant.

Key procedural points in the French voluntary disclosure context include:

• Amended returns: A taxpayer may file amended returns correcting past errors or omissions. If filed before any DGFiP notification, this typically attracts a lower interest charge and reduced penalties under the bonne foi framework.
• Service de traitement des déclarations rectificatives (STDR): The dedicated regularisation unit that handled the bulk of voluntary disclosures in the 2013–2019 period has closed, but the DGFiP continues to accept regularisation requests through ordinary procedural channels.
• Criminal risk: Where amounts are significant and the pattern of non-compliance is systematic, French prosecutors may pursue fraude fiscale charges independently of or alongside the administrative audit. Voluntary disclosure before any criminal referral materially changes the risk profile, though it does not automatically preclude prosecution.
• Penalty structure: Administrative penalties for non-declared foreign accounts and unreported income can accumulate quickly. The applicable surcharges depend on the nature and duration of the default; no specific rates are assumed here, as the applicable scale is determined by French domestic law and the facts of each case.

For clients with historic exposure in France, the window for proactive regularisation before DAC8 data begins to flow into DGFiP systems in a systematic way is narrowing. We would encourage affected parties to seek advice without delay. Please contact us at info@ferrazwhitmore.com or through our contact page.

Cross-Border Dimensions: Residency, Treaties and EU Exchange

DAC8 is, by design, a cross-border mechanism. Its value to the DGFiP lies precisely in the fact that it captures activity that previously fell outside France's direct visibility – accounts held with platforms established in other EU member states, and, through the OECD CARF alignment, potentially beyond the EU in time.

Several cross-border scenarios create particular complexity in the French context:

• Tax residency disputes: An individual who claims to have become non-resident in France before realising crypto gains may face scrutiny if DAC8 data suggests continuing activity through accounts held during the disputed period. The DGFiP applies the domestic definition of fiscal domicile under Article 4 B of the Code général des impôts, which looks at habitual residence, centre of economic interests and professional activity. Treaty tie-breaker provisions are available where the relevant convention applies, but the burden of establishing non-residence rests with the taxpayer.
• Portuguese and other EU connections: Clients with cross-border exposure between France and Portugal – for example, individuals who relocated between the two countries or who hold assets through structures in both jurisdictions – should be aware that both DGFiP and Portugal's tax authority will receive DAC8 data through the exchange network. Our analysis of DAC8 readiness in the Portuguese context may also be relevant: DAC8 Readiness – Portugal case analysis.
• Withholding tax on distributions: Where French-source income is paid to a non-resident (for example, staking rewards or income from a French-domiciled crypto fund), withholding tax obligations may arise. The applicable rate depends on the relevant tax treaty or, in its absence, domestic French withholding provisions. DAC8 reporting may surface payments that were previously unreported for withholding purposes.
• Pillar Two and DAC9: Large multinational groups with French operations should note that GloBE information returns exchanged under DAC9 will be available to the DGFiP for Pillar Two enforcement purposes. This is a distinct layer from DAC8 but operates through the same administrative infrastructure.

Strategic Considerations for Businesses and Funds

For corporate clients, funds and crypto-asset service providers operating in France, DAC8 creates both operational and strategic imperatives. On the operational side, platforms that are in scope for DAC8 reporting must ensure their client due-diligence, data-collection and reporting systems are capable of generating the required returns for the 2026 data year. On the strategic side, the existence of systematic exchange data changes the risk calculus for any structure that has historically relied on limited information exchange.

Entities that use French corporate vehicles as part of a cross-border holding or trading structure should review whether their arrangements remain appropriate in a post-DAC8 environment. In particular:

• Group structures involving French holding companies or branches may need to reassess intra-group pricing and substance in light of the information now available to the DGFiP.
• Investment funds distributed in France but managed from another jurisdiction should confirm that their French distribution arrangements do not create unexpected DAC8 reporting obligations or French permanent establishment risk.
• Family offices and private wealth structures with French beneficiaries should review whether existing entity arrangements adequately separate non-French assets from French tax exposure, particularly where French impôt sur la fortune immobilière (IFI) or succession tax positions have not been recently revisited.

Our corporate law practice in France works alongside our tax team to advise on the structural implications of these developments. An overview of our corporate services in the jurisdiction is available at our France corporate law service page.

Enforcement Mechanics: From Data to Assessment

It is worth tracing the practical path from a DAC8 data receipt to a formal tax assessment under French procedural law, as the timeline and available responses differ at each stage.

The DGFiP receives exchanged data and cross-references it against filed returns. Where a discrepancy is identified, the first step is typically an informal demande de renseignements or a demande d'éclaircissements ou de justifications. Responding to these requests accurately and promptly is important: the manner of the response can influence both the scope of any subsequent audit and the DGFiP's assessment of good faith.

If the DGFiP escalates to a formal audit – whether a vérification de comptabilité for businesses or an ESFP for individuals – the taxpayer acquires procedural rights including the right to be assisted by an adviser and, in the case of a business audit, the right to consult the interlocuteur départemental. A proposition de rectification triggers a formal response deadline, and the taxpayer may contest the proposed reassessment through the administrative hierarchy and, ultimately, before the administrative courts.

Debt enforcement in France – where a tax debt is established and unpaid – may eventually involve proceedings before a commissaire de justice (formerly huissier de justice) and, in commercial debt contexts, potentially an injonction de payer. These are late-stage mechanisms; the overwhelming majority of disputes are resolved at the audit or administrative review stage. Nonetheless, understanding the full procedural chain underlines why early engagement – whether by responding promptly to DGFiP enquiries or by proactively regularising a position before contact is made – is the more prudent course.

Outlook: What to Expect Through 2026 and Beyond

The first DAC8 reporting cycle covers data from 1 January 2026. Crypto-asset service providers are in the process of implementing the required systems; the DGFiP will begin receiving structured exchange data as reporting deadlines fall due under the applicable national rules. The practical impact on audit selection and enforcement activity in France will build progressively through 2026 and into subsequent years as the volume of exchanged data grows and the DGFiP's analytical capacity in this area develops.

Several developments merit continued monitoring:

• France's national implementing measures for DAC8 and DAC9, and the DGFiP's guidance on reporting procedures and penalty application.
• The AMF's and ACPR's evolving regulatory posture as MiCA implementation progresses alongside DAC8 reporting obligations.
• Further Cour de cassation or administrative court jurisprudence on the tax characterisation of crypto-assets, staking, lending and related activities.
• OECD developments in CARF implementation beyond the EU, which will progressively extend the geographic reach of automatic exchange to cover platforms currently outside the EU reporting framework.
