Is Crypto Legal in France?

You hold crypto-assets, you realise a capital gain, and worry sets in quickly: tax audit, a forgotten foreign account, a misunderstood “professional” classification, or a non-compliant platform. French law treats crypto-assets as assets governed by Regulation (EU) 2023/1114 (MiCA), with a legal, tax and AML/CFT (anti-money laundering and counter-terrorist financing) framework aimed first at traceability and the prevention of money laundering. The rules remain technical, and errors often stem from a wrong reflex: reasoning “as if it were money”, when the tax authorities reason “as if it were an asset”.

Legal framework for crypto-assets: what the law classifies, and what it does not

In France, cryptocurrencies are not legal tender. Since 1 July 2026, French law has treated them as falling within the category of crypto-assets defined by the MiCA Regulation. This classification has practical consequences: you do not follow the regime of a bank account, but that of an asset whose value fluctuates. Generally, this approach calls for a logic of evidence: origin of funds, transaction history, proof of acquisition, and valuation records.

For the definition of crypto-assets, the Monetary and Financial Code refers to Regulation (EU) 2023/1114 (MiCA), which distinguishes in particular asset-referenced tokens, e-money tokens and other crypto-assets. This definition often serves as the entry point for classifying a transaction, and therefore for identifying the applicable obligations. Unique and non-fungible crypto-assets (NFTs) are excluded from the scope of MiCA. The law is not limited to the technology: it follows the economic function and the service provided.

You can cite Article L. 54-10-1 of the Monetary and Financial Code (in French) as the classification reference, without automatically inferring a single tax regime from it. Most often, taxation depends on the type of transaction carried out, its frequency, and the context of your activity. Barring specific circumstances, the same person may fall under different regimes depending on the exact nature of the flows.

Tax rules: basic principles, and common mistakes that prove costly

The taxation of crypto-assets rests on a simple principle: tax generally targets the disposal or the realisation of a gain, not mere holding. In practice, the difficulty lies in identifying the taxable event, calculating the capital gain correctly, and documenting the transaction. The most frequent confusions concern crypto-to-crypto exchanges, conversions, and the treatment of fees. Generally, incomplete records trigger the worst scenarios: unfavourable reconstruction, rejection of supporting documents, or penalties.

For individuals, the reference regime is set out in the Tax Code, based on capital gains on crypto-assets. The reference text remains Article 150 VH bis of the French Tax Code (CGI) (in French). Depending on the situation, tax arises on a taxable disposal, with specific reporting arrangements. In principle, you must reason on the overall capital gain, and not on a poorly framed “transaction by transaction” intuition.

Reporting is the other risk area. You must declare these gains in the prescribed form and keep the calculation records. Barring specific circumstances, failure to declare exposes you to sanctions, with penalties depending on the conduct found. Most often, the problem does not stem from organised fraud, but from an oversight or a poor tracking tool. The defensive strategy is to gather and preserve your supporting documents before any request from the tax authorities.

Accounts and platforms: what the tax authorities expect in practice

You use a foreign platform, a custodial wallet, or a service not established in France: the question of reporting obligations becomes central. With your income tax return, you must declare the crypto-asset wallets opened, held, used or closed abroad (Article 1649 bis C of the CGI (in French)). The tax authorities expect a minimum level of traceability: dates, amounts, counterparties, and valuation method. Generally, you must keep the documents for the applicable period, so that you can respond to a request for justification.

Sanctions for omissions can be high, but they depend on the circumstances and the applicable texts. Avoid any automatic extrapolation: the same irregularity does not always produce the same consequence. In practice, spontaneous regularisation can change the analysis, but it does not systematically remove all risk. Barring specific circumstances, you benefit from documenting before correcting, so as not to create inconsistencies.

Mining, staking, trading: when the tax authorities may switch to a “professional” regime

You mine, you stake, you trade frequently: the line between managing private wealth and a professional activity remains a sensitive area. In principle, the tax authorities analyse factual criteria: frequency, organisation, material resources, speculative intent, and the size of the income. You cannot rely on a label, a pseudonym, or a mere statement of intent. Generally, it is the body of evidence as a whole that decides the classification.

For mining, the tax authorities’ guidelines provide for taxation in the category of non-commercial profits (bénéfices non commerciaux, BNC; BOI-BNC-CHAMP-10-10-20-40), but the analysis depends on the exact arrangements. You must describe the activity, the costs, the regularity, and the income received, in order to classify the flow correctly. For intensive trading, gains fall within non-commercial profits (BNC) when the transactions are carried out under conditions similar to those of a professional activity (Article 92 of the CGI (in French)). Barring specific circumstances, rigorous bookkeeping and tracking are your best protection.

CASPs and AML/CFT obligations: what professionals must do, and what it changes for you

Players that provide crypto-asset services are subject to a specific regime, with compliance requirements. Since 1 July 2026, the former digital asset service providers (PSAN, former French regime) have given way to crypto-asset service providers (CASP, PSCA in French): they must be authorised in accordance with Article 59 of the MiCA Regulation (Article L. 54-10-4 of the Monetary and Financial Code (in French)), on an application filed with the AMF (French financial markets authority), and apply AML/CFT rules. You experience it every day: KYC, proof of the origin of funds, transaction monitoring, and sometimes frozen flows. Generally, these requirements increase with high volumes or patterns deemed atypical.

In AML/CFT matters, professionals must identify customers, analyse transactions, and report certain suspicions. The text and practice impose a level of vigilance proportionate to the risk. Never assume that a block stems from illegality: it may come from an automated compliance process or a missing document. Barring specific circumstances, you resolve matters faster by providing consistent supporting documents, rather than by multiplying contradictory explanations.

Platforms and user information: transparency, fees and risks

Digital platforms (in French) operating with the public must frame the information given to users, in particular on fees, risks, and execution arrangements. In principle, transparency aims to prevent misleading practices and contractual blind spots. You must read the terms, but above all you must understand the points that give rise to disputes: custody, withdrawal times, unilateral changes to the rules, and incident handling. Most often, legal risk arises from a misunderstanding of the exact service provided.

ICOs and tokens: regulation, liability and careful drafting

Public offers of tokens are subject to a framework that seeks to balance innovation and protection. The former optional AMF visa has disappeared: a public offer of crypto-assets (other than asset-referenced tokens and e-money tokens) falls under Title II of the MiCA Regulation, with notification of a white paper to the AMF (Article L. 552-2 of the Monetary and Financial Code (in French)). On the other hand, liability may be incurred if the information provided proves inaccurate, incomplete, or misleading. Generally, the main risk does not come from the word “ICO”, but from the commercial promise or the way the return is presented.

You must deal separately with the regulatory question and the tax question of the funds received. Raising funds may trigger, depending on the legal structure and the place of establishment, accounting and tax obligations. Barring specific circumstances, the analysis turns on the classification of the token, the use of the funds, and the consideration promised. Avoid categorical assertions, as structures vary enormously.

Income in crypto: salaries, services, gifts, estates

You receive income in crypto-assets, as salary, for a service, or as a payment: in principle, you must value it in a reference currency at the time of receipt. The classification depends on the legal relationship: employment contract, independent services, or other. Generally, the tax authorities expect a consistent and reproducible valuation method, with evidence of prices or conversion. Barring specific circumstances, the absence of valuation records makes the discussion unfavourable in the event of an audit.

Gifts and estates involving crypto-assets follow, in principle, the ordinary rules, with one specific difficulty: proving existence and value at a given date. You must plan for access to the keys, the inventory, and the traceability of origin. Most often, families discover the problem too late, when technical access is lacking. Barring specific circumstances, you preserve the evidence without exposing the keys, through careful estate planning.

Accounting and businesses: integrating crypto-assets without improvising

A business that holds or receives crypto-assets must record them in its accounts under French rules, with appropriate conversion and documentation. In principle, you record transactions in euros, with a stable and justifiable conversion method. You must also deal with valuation issues at year end, depending on the accounting classification adopted. Generally, the main risk comes from “manual” tracking that is incomplete and does not reconcile with the platform records.

For VAT, avoid shortcuts. The analysis depends on the nature of the service and the place of taxation, not on the fact that payment arrives in crypto. In principle, the invoice must show the equivalent value in euros, with the usual mandatory particulars. Barring specific circumstances, you do not “escape” VAT by magic just because the payment is unusual.

What a lawyer does: make your position legally sound, document, challenge, without promising an outcome

Facing the tax authorities, you rarely win with general arguments. Most often, you win with a file: proof of acquisition, history, calculation method, consistency of returns, and a factual explanation. That is exactly the approach of a cryptocurrency law firm: identify the applicable regime, make your reporting legally sound, and build a defensive position. The lawyer can also act during an audit, a request for information, or litigation, by framing the exchanges and avoiding irreversible mistakes. Barring specific circumstances, the priority is to reduce uncertainty, not to “guarantee” an outcome.
