International owners with exposure to French assets or French-group entities are operating in a more complex intersection of regulatory and tax change than in recent years. The simultaneous arrival of EU crypto-market rules, expanded cross-border information exchange, and successive French finance laws requires a targeted review of legal structures, reporting processes and operational tax controls.

This note explains the practical checks international owners should prioritise in France’s tax landscape after MiCA and recent finance-law moves. It highlights immediate compliance triggers, structural risks and operational actions to reduce exposure to new taxes, reporting obligations and transfer-pricing or audit challenges.

MiCA and crypto-tax interplay

The EU Markets in Crypto-Assets Regulation (MiCA) has clarified the supervisory and market framework for a wide range of crypto-assets and providers; certain MiCA provisions (notably for asset-referenced tokens and e-money tokens) entered application in mid‑2024, while the wider MiCA regime has moved into full application and supervisory convergence phases. Stakeholders should therefore expect tighter market conduct oversight and clearer licensing/registration requirements for entities active in the EU crypto space.

From a tax perspective, MiCA’s primary effect is indirect: it increases transparency and formalisation of crypto-asset service providers (CASPs) and issuers, which in turn facilitates tax administration access to crypto-related activity and documentation. Owners must therefore assume that previously informal arrangements or opaque chains of custody will be easier for administrations to trace.

Practically, international owners holding crypto-assets through French entities, wallets hosted in France or through EU CASPs should (i) validate legal status and licences of service providers, (ii) map token classifications for tax purposes, and (iii) ensure transaction and cost-basis records are robust enough to support gains/losses and VAT/indirect-tax positions on audit. The regulatory-normalisation trend under MiCA increases the probability that tax audits will rely on supervised market records.

DAC8 and reporting obligations for crypto assets

The EU Directive commonly referred to as DAC8 extended automatic information exchange to reportable crypto-asset transactions; the EU framework requires CASPs to report client-level data to tax authorities from 1 January 2026 (data collection and reporting cycles may start earlier for certain providers). This obligation materially increases the quantity and granularity of information French and foreign tax authorities will receive about cross-border crypto dealings.

France has implemented DAC8 measures at national level (including administrative decrees adapting reporting rules to French practice), which means CASPs and any entities acting as intermediaries must confirm whether French rules capture their activities and whether they face French filing duties or cooperation requests. International owners should therefore verify whether their custodians or platforms are in scope and what client data will be reported to the French tax administration.

Action items for owners: confirm contractual documentation with CASPs (representation on who reports), obtain annual statements that allow reconciling declared transactions with tax returns, and prepare to supply supporting documentation in France for fiscal years affected by DAC8 reporting. Consider also immediate remediation where historic records are incomplete, and assess voluntary disclosure where prior filings were inadequate.

New finance-law measures affecting cross-border owners

The French Finance Law for 2026 introduced measures that directly affect non-resident and cross-border structures, most notably rules creating a specific tax on non-operational assets held by certain holding companies and detailed exit/entry taxation provisions linked to changes in tax residence. These changes reflect a legislative intent to broaden the French tax base on passive or wealth-like assets held through corporate wrappers.

Key thresholds and conditions (for example minimum portfolio value, ownership levels and the passive income test) determine whether a holding vehicle becomes subject to the new asset tax; the measure generally targets holdings with significant non-operational asset values and substantial passive income ratios. The law sets compliance, valuation and reporting mechanics and fixes application to fiscal years closing from 31 December 2026.

International owners should therefore (i) run a value-and-income test on holding structures with French connections; (ii) determine whether indirect holdings or chains of control bring entities within the scope; and (iii) plan valuation methodology and documentation. Where thresholds are close, consider restructuring, reallocation of assets or operationalisation of passive assets to avoid unintended taxation once the rule becomes operative.

Pillar Two and multinational tax exposure

France transposed the OECD/GloBE minimum-tax rules into domestic law via recent finance laws and guidance, which means groups with French constituent entities must consider the 15% effective minimum tax (including the application of Qualified Domestic Minimum Top-up Tax (QDMTT) or top-up through the Undertaxed Profits Rule / UTPR). The practical consequence for many multinationals is higher consolidated tax burden in the presence of low-tax jurisdictions within the group.

For international owners, the critical checks are (i) whether an entity in the group located in France materially contributes to the group’s Pillar Two top-up; (ii) calculation and documentation of effective tax rate (ETR) by jurisdiction; and (iii) the interplay with French transfer-pricing positions, CFC rules and domestic tax incentives. France’s implementing rules also include reporting and payment schedules that interact with corporate tax returns.

Recommended steps include building a reliable jurisdictional ETR model, reconciling tax accounting to local filings, running simulations of the top-up exposure under QDMTT/UTPR scenarios, and deciding whether to elect a QDMTT (where available) or anticipate UTPR allocations. Early engagement with tax advisers and the French tax authorities can reduce surprises at assessment time.

Real estate, holding companies and the new asset tax

Real estate remains a central exposure for international owners of French assets. The 2026 finance law provisions on a tax targeting non-operational assets held by certain companies explicitly include real estate in the valuation base and set valuation, debt‑netting and aggregation rules. Owners using French or foreign holding companies to hold French property must therefore re-evaluate both ownership chains and financing arrangements.

Beyond the new asset tax, existing French taxation on real estate (income from French real estate, capital gains, local taxes and specific anti-avoidance rules) continues to apply to non-residents and to controlled corporate structures. With additional reporting and possible withholding implications, a holistic review of property ownership, intercompany leases and management fees is necessary to avoid mismatches and double taxation.

Concretely, international owners should consider: (i) whether property should be operated through an active French subsidiary rather than a passive holding vehicle; (ii) potential benefit of pre-closing restructuring prior to the law becoming effective for fiscal years closing on or after 31 December 2026; and (iii) tightening of intercompany documentation, valuations and arm’s-length proofs to withstand French audit scrutiny.

Preparing for audits, disclosures and operational compliance

Taken together, MiCA, DAC8 and French finance laws increase data flows to tax administrations and raise the probability of focused audits on crypto, passive asset holdings and cross-border profit allocation. French tax authorities have also updated administrative guidance and domestic reporting processes in recent years, reinforcing the need for robust, auditable records.

Operational checks for international owners should include (i) a documentation audit (transaction-level records, wallets, proof of ownership, valuations), (ii) contractual reviews with platforms, custodians and managers to allocate reporting responsibilities, and (iii) internal controls to ensure timely and accurate disclosures under DAC8, Pillar Two and domestic French filing requirements. Where records are incomplete, consider controlled voluntary disclosures and remediation plans.

Finally, consider strategic preventative steps: seek advance tax rulings where available, update transfer‑pricing documentation to reflect current operational facts, and re-evaluate entity-level elections (e.g., tax residency, QDMTT election options) with French counsel. Early dialogue with advisors and, where appropriate, with French tax authorities will reduce the risk of surprise assessments and sanctions.

In the short run, owners with crypto exposure or large passive asset holdings should prioritise record remediation, review of ownership chains and dialogue with service providers about DAC8 reporting. Over the medium term, structural changes, including recharacterisation of holdings or operationalisation of assets, may be necessary to align tax risk with commercial objectives.

Because the French tax and regulatory environment has evolved rapidly during 2024,2026, every international owner with French touch‑points should treat these developments as a prompt for a dedicated, documented compliance review. That review must combine legal, tax and operational teams and, where necessary, rely on French tax litigation and structuring specialists to preserve value and manage risk in cross-border holdings.
