France recorded an estimated $9.4 billion in on-chain crypto gains, income, and payments during 2025 as European tax authorities begin collecting more detailed transaction data under new reporting rules.
The Chainalysis estimate does not represent unpaid tax or government revenue. It covers several types of economic activity that receive different tax treatment under French law.
France Logs $2.5B in Estimated Crypto Gains and $5.2B in Payments
Chainalysis divided France’s $9.4 billion into about $2.5 billion in realized gains, $1.7 billion in income and $5.2 billion in crypto payments. Income includes activity such as mining, staking and lending, while the payments category covers merchant services and peer-to-peer economic activity.
The analysis covers Bitcoin, Ethereum, Solana, Tron, BNB Smart Chain and Base. Activity taking place entirely inside centralized exchanges is not visible on-chain, meaning the estimate does not capture the full French crypto market.
French taxpayers separately reported €368 million in crypto capital gains for the 2024 tax year through about 24,000 filings. That figure cannot be directly compared with the $9.4 billion estimate because it covers a different year, currency and narrower category of activity.
DAC8 Collects Crypto Transaction Data Throughout 2026
The European Union’s DAC8 reporting regime began applying on January 1. Crypto service providers must collect identifying information and transaction records for reportable EU-resident customers throughout 2026.
Covered activity can include crypto-to-fiat exchanges, crypto-to-crypto transactions and transfers involving customer-controlled addresses. France has implemented the requirements through its domestic tax framework and is preparing its reporting infrastructure for DAC8 and CARF submissions.
EU Tax Authorities Exchange First DAC8 Data By September 2027
Providers will submit their first reports covering 2026 activity during 2027. Information concerning EU taxpayers must then be exchanged between national tax authorities by September 30, 2027.
France already requires residents to disclose qualifying crypto accounts and wallets held with foreign providers.
DAC8 will give French tax authorities an additional source of transaction information supplied directly by crypto businesses. The first reporting cycle will cover activity collected throughout 2026, with cross-border information exchange due by September 30, 2027.
