France’s fiscal and regulatory landscape for cross-border groups and non-resident wealth has evolved rapidly over the last three years, driven by EU-level measures and domestic Finance Acts. Companies and high-net-worth individuals who hold assets across jurisdictions must now manage overlapping obligations, from global minimum tax compliance to new reporting duties for crypto wallets, while ensuring operational and corporate resilience.

This article outlines practical steps to secure international holdings and strengthen corporate resilience in light of France digital-asset rules and broader fiscal reforms. It is written for corporate groups, executives and non-resident clients who require concrete, compliance-focused guidance compatible with recent EU and French developments.

Regulatory snapshot: what has changed and why it matters

At the European level, the Markets in Crypto-Assets (MiCA) regulation established a harmonised regime for issuers and service providers active in crypto markets and began applying for many provisions from 30 December 2024; France has actively re-cast its national supervisory approach during the transitional period to align with MiCA requirements.

The EU also adopted enhanced tax-transparency measures for crypto assets through the Directive commonly referred to as DAC8, which requires member states to collect and exchange information on reportable crypto transactions starting in calendar year 2026. This significantly expands the cross-border reporting perimeter for intermediaries and platforms.

Domestically, successive French Finance Acts, most recently the 2026 Finance Act, and tax authority guidance have adjusted corporate rules, reporting thresholds and enforcement priorities relevant to cross-border groups and wealthy individuals. These fiscal reforms interact with new digital-asset requirements to increase both reporting obligations and audit risk for international holdings.

Reporting obligations for digital-asset holdings and wallets

France has introduced detailed reporting duties for certain digital-asset wallet references and positions, requiring taxpayers and entities to declare specified identifiers and holdings when applicable; these rules were integrated into the tax code and linked to MiCA-era obligations.

For intermediaries and platforms that service French persons (residents and certain non-residents), the combined effect of DAC8 and national measures means enhanced operational reporting, greater information exchange with other EU tax authorities, and potential use of exchanged data in tax audits. Companies must therefore map flows and identify which entities and systems are within scope.

Practical consequence: advisers and treasury teams should compile a precise registry of wallets, custodians, and third-party platforms used by group members and close clients, and validate chain-of-custody and KYC documentation to withstand cross-border requests and administrative exchanges. This registry becomes a primary defence in case of inquiries under the new reporting frameworks.

Tax structuring and Pillar Two resilience for multinational groups

The OECD’s Pillar Two (GloBE) minimum tax rules have been transposed and are operational across many jurisdictions, including measures applied in France for financial years starting on or after 31 December 2023; French administrative guidance and subsequent finance bills have clarified application details and transitional arrangements. Multinational groups must assess top-up tax exposure, reporting requirements and the interaction between local tax credits and the IIR/UTPR mechanisms.

Structuring that previously relied on low-tax jurisdictions or complex intra‑group financing arrangements must be reassessed for effective tax rate impact and for the administrative burden of new disclosures. Legal entities that hold international investments should model GloBE outcomes and document commercial rationale to reduce audit and dispute risks.

Actionable step: update the group’s tax-risk appetite and compliance playbook to include GloBE calculations, roles for finance and tax teams, and decision trees for whether to elect qualified domestic minimum top-up regimes or rely on international relief mechanisms.

Custody, operational resilience and supervisory expectations

The French market regulator (AMF) and other authorities have emphasised orderly transition to the MiCA framework and stronger oversight of service providers, particularly custodians and platforms that hold client assets. Supervisory priorities include safeguarding client assets, business continuity planning and orderly wind-down arrangements for unauthorised providers.

For multinational groups, this means verifying that custodial arrangements comply with both the host jurisdiction’s MiCA-aligned rules and the group’s internal segregation and insolvency protections. Where third-party custody is used, contractual protections, insurance and contingency plans must be reviewed and stress-tested.

Boards should require evidence of operational resilience from service providers (penetration testing, recovery time objectives, and client-data integrity checks) and establish escalation protocols linking operational incidents to tax and regulatory reporting obligations.

Audit preparedness and litigation risk management

Heightened reporting and more comprehensive information exchange translate into increased tax‑audit risk. French tax authorities and EU counterparts may use DAC8-derived datasets and national wallet reporting rules to trigger enquiries into undeclared income, valuation mismatches or transfer‑pricing anomalies involving digital assets.

To mitigate exposure, groups should: (i) centralise documentation that substantiates valuations and transactional purpose; (ii) reconcile on‑chain records with accounting systems; and (iii) maintain contemporaneous transfer‑pricing documentation where intra‑group digital-asset movements occur.

When disputes arise, an early litigation-readiness posture is essential: preserve evidence, obtain privileged tax and legal analyses, and consider pre-emptive disclosure where legal counsel advises it is beneficial to reduce penalties and interest.

Governance, controls and an operational checklist for executives

Executives must treat the evolving France digital-asset rules as both a compliance and a strategic risk issue. Key governance measures include appointing a senior owner for cross-border tax and crypto compliance, integrating tax and treasury teams, and ensuring the audit committee receives regular briefings on exposures and remediation plans.

A practical checklist: map entities and owners of offshore holdings; inventory custodians and wallet identifiers; run GloBE and local effective‑tax‑rate simulations; validate KYC and contractual protections with custodians; and document business rationale for cross-border arrangements.

Finally, ensure external advisers (tax, legal, custody) are coordinated and that a crisis playbook links operational incidents to tax reporting and disclosure obligations, this reduces response time and aligns communications with regulators and counterparties.

France’s fiscal and digital-asset regimes have increased transparency and compliance obligations for international holdings, but these changes also create an opportunity for groups to strengthen governance, clarify economic substance, and reduce long‑term tax and litigation risk. Proactive mapping, robust custody arrangements and clear governance will be decisive.

Advisers and boards should treat these developments as an urgent program: combine legal and technical expertise to update policies, run scenario testing against Pillar Two and DAC8/MiCA realities, and document decisions. Doing so secures value, preserves optionality and reduces exposure to surprise enforcement actions.
