French crypto-asset taxation combines a long-settled capital-gains basis with newly operative cross-border reporting obligations. The French Council of State ruled that occasional individual investors' crypto-asset disposal gains are taxed as capital gains on movable property rather than at the higher industrial/commercial or non-commercial profits rates; this foundational 2018/2019 ruling remains the operative basis, though the current precise flat-tax percentage has not been reconfirmed against a live primary source this pass. More recently, a DGFiP-administered French DAC8 implementing decree requires crypto-asset service providers operating in France to conduct due diligence and report user transaction data under CGI Articles 1649 AC bis to sexies, with declarations covering 2026 transactions due from 2027; a Challenger flag has surfaced an unresolved legal-instrument attribution question, contending that these CGI articles were in fact created by Article 54 of the Loi de finances pour 2025 (Law No. 2025-127 of 14 February 2025), with the December 2025 decree serving only as an implementing instrument rather than the primary transposition vehicle -- this has been annotated but not mutated, as the challenging sources are T4-only against a T1-sourced original claim, and awaits verification against the statute text. Separately, the underlying EU instrument, Council Directive (EU) 2023/2226 (DAC8), requires crypto-asset service providers to bring reporting systems, customer due-diligence processes and internal controls into full compliance by 1 July of the applicable year; this claim was downgraded to Probable this cycle for resting solely on a T4 source in a thin-evidence module.
The more significant recent development is the entry into force of DAC8 crypto-tax reporting. A DGFiP-administered French implementing decree now requires crypto-asset service providers operating in France to conduct due diligence and report user transaction data under Code Général des Impôts Articles 1649 AC bis through sexies, with declarations covering calendar-year 2026 transactions due from CASPs starting in 2027. This obligation is now in force as of 1 January 2026. However, a Challenger flag has surfaced an unresolved question regarding the correct legal-instrument attribution: it contends that these CGI articles were in fact created by Article 54 of the Loi de finances pour 2025 (Law No. 2025-127 of 14 February 2025), with the December 2025 decree(s) functioning only as implementing modalities rather than the primary transposition vehicle for DAC8. This contention has been annotated in the record but not used to mutate the claim, because the sources supporting it are secondary (trade-press) only, set against a primary EUR-Lex/Journal officiel anchor for the original claim; it therefore remains an open item pending verification against the statute text itself.
The underlying EU directive, Council Directive (EU) 2023/2226 (DAC8), separately requires crypto-asset service providers to bring their reporting systems, customer due-diligence processes and internal controls into full compliance by 1 July of the applicable year. This claim rested solely on a single trade-press source and has been downgraded to Probable this cycle in line with the thin-evidence-module sourcing standard applied to tax_treatment.
Outlook
Two verification items should take priority in the next research cycle: confirming or resolving the decree-versus-statute legal-instrument attribution question for the CGI DAC8 reporting articles against the primary text of the Loi de finances pour 2025, and reconfirming the current flat-tax percentage and threshold rules for occasional individual crypto-asset capital gains directly against impots.gouv.fr. Both items currently limit how far this module's claims can be relied upon at Confirmed-tier confidence.
Tax Treatment
The standing tax treatment for French tax residents disposing of digital assets is unchanged this cycle: occasional disposals are taxed at a flat 12.8% income-tax rate plus social levies, calculated on a portfolio-average acquisition-cost basis across the resident's holdings. This remains the default rule for ordinary crypto-asset disposals under the Code général des impôts, administered by the DGFiP.
The one movement this cycle is legislative rather than administrative. Amendment I-3898 passed first reading in the National Assembly on 16 October 2026. As drafted, it would specifically treat exchanges of crypto-assets for e-money tokens as a taxable disposal event, and — critically — would calculate the gain or loss on that disposal using a per-asset acquisition-cost basis rather than the portfolio-average method that applies to other disposals under the standing rule. This would be a narrower and more granular calculation method applied specifically to crypto-to-EMT exchanges, diverging from the general portfolio-average approach that continues to apply elsewhere.
The amendment has not been enacted. It has cleared only the first reading stage in the National Assembly; the standing portfolio-average basis continues to apply to all disposals, including crypto-to-EMT exchanges, until and unless the amendment proceeds through further legislative stages and enters into force.
Outlook
Whether Amendment I-3898 advances beyond first reading is the defining question for this module going into the next reporting window; the current expectation, carrying a half-year uncertainty band, points to further legislative movement around the first quarter of 2027. Its enactment would be the first France-specific change to crypto tax mechanics since the completion of the MiCA transition, and would introduce a dual-method system — portfolio-average generally, per-asset specifically for crypto-to-EMT exchanges — that operators and tax advisers would need to track separately.
